Hence, earning profit is 2 the most important objective of business, but it can never be the 22 sole(a) The objective. principle highlighted in the given case is the principle of 1 contribution. (b) Many a times a person takes more than one policy to cover the same risk which is known as double insurance. According 2 to the principle of contribution, every liable insurer must share the losses in proportion to the sum assured by each of them. This principle basically gives a right to the insurer (who has paid an insurance premium and made a claim) to call upon other insurers who are liable to pay and contribute. For example, if a person has double insurance over the same property (double insurance does not necessarily mean two insurance policies, it can be more than two insurance policies also) and he claims money from one of the insurers. The insurance company pays out the amount of claim. After doing so, the insurance company which has paid the amount of claim has the right to call upon other insurers to pay the amount of claim in proportion to the sum assured by them or coverage offered by the insurance policy.

Hence, they are able to provide better information to manufacturers regarding customer’s tastes and 1 preferences, needs of customers, recent market trends and level of competition. This helps manufacturers to fulfil customers’ demands and make tailor-made products to suit customers’ requirements. 3) Financial assistance: Generally, wholesalers make payment of products in cash. This helps manufacturers to avoid blocking 1 their capital in stocks. Sometimes advance money is provided by wholesalers to manufacturers for bulk orders so that they do not face any shortage of finances and can complete the order on time. 4) Marketing activities: Wholesalers extend help in the distribution of products to a large number of retailers spread over a vast geographical area. This is beneficial for 1 manufacturers in a way that they are relieved from performing any marketing or promotional activities and only concentrate on production. OR Characteristics of fixed shop retailers: 1) They have greater resources which help them to operate at 1 a large scale as compared to itinerant traders. However, sometimes they operate on a small scale too. 2) They deal in a wide range of products—from durable to 1 non- durable products. 3) They have greater credibility in the minds of consumers 1 because of providing ancillary services such as home delivery, credit facility and guarantees for products.

Despite their contributions, two major areas which affect and slow down small businesses are finance and marketing. The government therefore has taken initiatives to get rid of these issues. They have established the following agencies to assist and support small businesses: 1) National Bank for Agriculture and Rural Development (NABARD) was established in 1982 with the intention of 2 promoting integrated rural development which involves agriculture, small-scale industries and cottage and village industries. 2) The Rural Small Business Development Centre (RSBDC) is a one-of-a-kind institute by the World Association for 2 Small and Medium Enterprises. It is sponsored by NABARD and works for the betterment of socially and economically disadvantaged individuals and groups and aims at promoting technical support in rural areas to current and prospective micro and small entrepreneurs. 3) National Small Industries Corporation (NSIC) was created in 1955 to encourage, assist and foster the growth of small 2 business units in the country.

Advantages of chain stores and multiple shops: 1) Economies of scale: These shops enjoy the benefit of 1 economies of scale as they have a centralised procurement system which fetches them huge discounts. 2) No bad debts: As these stores/shops only accept cash as a 1 mode of payment for any kind of sale, there is no chance of bad debt. 1 3) www.topperlearning.com Elimination of middlemen: These shops sell directly to 9 consumers; therefore, they are successful in

32 Factors determining the choice of form of organisation: 1) Cost of setting up a business organisation: Every form of business organisation needs some initial capital for its establishment. The company form of organisation incurs the maximum cost and involves complex formalities, whereas 1 the sole proprietorship form of business is the most inexpensive form with minimum legal formalities. In case of a partnership, there are less legal formalities and limited scale of operation, so the cost of setting up a partnership firm is low. 2) Nature of business: The type of business one wants to conduct is the most important factor in determining the form of business. If one wants to have direct personal contact with 1 customers, then a sole proprietorship would be the best form. If one is willing to set up a large manufacturing unit, then a company form of business would be preferred. However, for providing professional services, a partnership form of business would be most suitable. 3) Capital: It is one of the important factors which help in

www.topperlearning.com 1 1

determining the choice of the organisation. A sole proprietorship form of business requires minimum investment/capital. If one has adequate funds, then he can opt for a partnership form of business. However, huge 1 financial resources are required for a company. So, if the operations are carried out on a large scale, then the company form of business is the most suitable, whereas for medium or small businesses, a partnership or sole proprietorship form of business is most suitable. From the point of view of growth and expansion, a company is the most suitable form of business as it has the capacity to raise funds required to expand its scope of operations. 4) Liability: Liability of different forms of business organisations also plays an important role in choosing a suitable form of business organisation. In case of sole proprietorship and partnership, the liability of the sole proprietor and the partners, respectively, is unlimited. This means that the personal assets of the owners/partners will be utilised to pay off the debts (if needed). Under the joint 1 Hindu family business, only the karta has unlimited liability. Unlike other forms of business organisations, the liability of the members of a cooperative society and a company is limited, so the creditors can claim repayment of debt only to the extent of the assets owned by the business organisation. Taking into consideration the extent of liability and the risk involved, a company form of business organisation is considered most suitable. 5) Management ability: In a sole proprietorship, there is a single owner who performs all the functions of management. Hence, he cannot be an expert in all areas. On the other hand, professional experts are hired in case of business organisations like a partnership and a company. To enable efficient decision making, work must be divided 1 among different members so that they can specialise in a particular area or field of work. In some cases, this may also lead to conflicts due to difference of opinion among members. Additionally, if the operations are carried out by the organisation on a large scale and are of a complex nature, it will require professional management. In such cases, the company form of business organisation proves to be suitable. In cases wherein the operations are carried out on a small scale and are not very complex, the sole proprietorship or partnership form of business organisation must be adopted. In this way, the nature of operations/business activities and requirement of professional management is an important factor to be considered while choosing an organisation. 6) Continuity: In a sole proprietorship, continuity depends on www.topperlearning.com the people and the events which take place such as death 1 or insanity of owners, insolvency etc. However, the 1 2

cooperative society and company. So for short-term business plans, a sole proprietorship or partnership form of business organisation is most suitable. However, for a long- term and permanent business, the company form of business proves to be most suitable. OR Features/characteristics of a partnership: 1) Formation: The Indian Partnership Act, 1932, governs the partnership form of organisation. To form a partnership, there must be a legal agreement (oral or written) governing the terms of partnership between the partners to run the 1 business and share the risks and profits of the business. The purpose of this agreement should be lawful and must focus on earning profits. Any such agreement entered into for the purpose of charity will not constitute a partnership. 2) Liability: All the partners in the firm have unlimited liability. So, in case the assets of the partnership firm are insufficient to repay the debts, the partners will have to repay the debt using their personal assets. The partners are jointly and individually liable for debt payments which 1 means that all the partners are jointly responsible for payment of debt and they are individually liable up to the extent of their share in the partnership firm. 3) Risk-bearing and profit-sharing: In a partnership form of business organisation, risks are borne by the partners jointly, whereas if the business earns profits, these profits are shared as per the ratio mentioned in the partnership 1 agreement. Similarly, in cases of losses, they are also shared in the same ratio between partners. 4) Control and decision-making: The control over the business and decision-making power of the business is shared among partners. This means that all the decisions are taken with mutual consent. Joint efforts of all the partners are required to manage a partnership firm. 1 5) Number of partners: To start a partnership firm, a minimum of 2 partners are required. The maximum number of partners in a partnership firm is governed by Section 464 of the Companies Act, 2013. It lays down that the maximum number of partners in a partnership firm can be 100, subject 1 to the number prescribed by the government. As per Rule 10 of the Companies (Miscellaneous) Rules 2014, the maximum number of members at present can be 50. 6) Mutual agency: In a partnership form of business organisation, business is carried out by all or any of the partners on behalf of other partners. Hence, every partner is a principal and an agent. Here, the partner carrying out 1 business on behalf of the others is the agent. Being an agent www.topperlearning.com of other partners, he/she binds them through his/her 1 actions. He/she is also a principal in the sense that he/she 3

partners. 33 Principles of insurance: 1) Utmost good faith: The contract of insurance is based on utmost good faith. According to this principle, both insurer and insured should display good faith towards each other with respect to the contract. It is the duty of the insured to disclose all the material facts, risks, details to the insurer and the insurer must clearly explain all the terms and conditions 1 of the contract. Thus, this contract binds the proposer to reveal all the material facts relating to the proposed insurance which will help the insurer to make decisions relating to the acceptance of the proposal, the amount of premium to be charged etc. In case the insured fails to disclose any material facts related to the contract of insurance, then the contract will be voidable at the option of the insurer. 2) Insurable interest: This principle states that the insured 1 should have some kind of insurable interest in the subject matter of insurance. Under a contract of insurance, the specific interest of the insured in the subject matter of insurance is insured. For example, in case a property is insured, the interest of the insured must exist at the happening of the event, whereas in case of life insurance, it is necessary to have an insurable interest at the time when the insurance is affected and not necessary at the time of maturity. Hence, having an insurable interest is a necessary condition, as without this, it would become a fraudulent activity not acceptable under law. 1 3) Indemnity: The insurer should compensate the insured for the entire loss so that there is no difference between the insured’s financial position before and after the loss. Here, the loss suffered by the insured and the compensation paid by the insurer are measured in terms of money. This principle is not applicable to life insurance because it is not possible to estimate the amount of loss incurred due to death. Example: If an individual has taken a policy worth Rs 1 lakh but suffered a loss of Rs 75,000, then the insurance company will compensate Rs 75,000 only and not Rs 1 lakh. 1 4) Subrogation: This principle states that after compensation is received by the insured, the insurer steps into the shoes of the insured, i.e. once the person claims the compensation for the loss, the ownership of that specific thing/property shifts to the insurer. This is because the insured has already received the amount for the loss, and thus, he is not allowed to sell the damaged property to make a profit. Example: A person who has damaged car parts in a car accident is entitled to receive compensation for those www.topperlearning.com parts. After receiving the compensation, the ownership of the 1 10 damaged parts will be given to the insurer.

after taking the insurance. Example: If a person has taken fire insurance for his factory and the factory catches fire. In this situation, the person should act prudently and take steps which will help in reducing the loss or damage and not act carefree because there is an insurance cover for the same. In case when such reasonable care is not taken, the insurance company can deny the claim made by the insured. 6) Proximate cause principle: According to this principle, an insured person can be awarded compensation only for losses which are caused by the risks covered in the policy. 1 Also, when there is more than one cause, the proximate cause (i.e. the forthright/direct cause) is considered by the insurance company for compensation. OR

(a) Yes, Rama provides a service to Mrs Shah. (b) Services are intangible economic activities which are consumed at the point of sale. These activities provide satisfaction of wants but may not necessarily involve the sale of a product. Also, such activities cannot be kept in 1 stock. Examples of services include the services of a lawyer or doctor. (c) Four features of service:

1) Intangibility: Services cannot be touched or seen but can

only be experienced. Hence, they are said to be intangible.

The quality of the service cannot be judged before

buying/experiencing the service. Thus, it becomes essential

for the service provider to offer an optimal service 1 experience which satisfies customers. For example, a

customer taking a treatment in a spa must have a good

experience of the service.

2) Inventory: One of the important characteristics of a service

is that it cannot be kept aside to be consumed in the future.

So, the need for maintaining an inventory does not exist. If

the service is not used at the right time, then it results in 1 the loss of that service. Therefore, the demand and supply

of services need to be regulated as it must be

provided/supplied as and when demanded by consumers. It

cannot be performed early and stored to be used later. For

example, the ticket to an amusement park can be preserved;

however, the experience of the amusement park can only be

enjoyed at the time when the service is provided by the

amusement park.

3) Inseparability: A service is an activity whose production

and consumption occur at the same place. Thus, these

activities seem to be inseparable in nature. It is possible in 1 case of goods that they are produced at a particular time and consumed later. The same is not possible in case of services, www.topperlearning.com 11 as after production, they need to be consumed immediately.

there are doctors available in the hospital but there are no patients, then no services can be provided. Hence, the production of service and the presence of consumers for its consumption are simultaneous and inseparable activities. 4) Involvement: In case of all the services, it is very important 1 for customers to participate in the process of service delivery. This provides a chance for customers to get the services modified according to their specific needs. 34 Procedure involved in importing machinery from France by Suchitra Pvt. Ltd.:

1) Trade enquiry: The first step in the import procedure is to make a trade enquiry. With the help of a trade enquiry, the 1 importer approaches various exporters in order to obtain information regarding the price and terms and conditions of goods. After receiving a trade enquiry, the exporter provides the details of goods such as quality, size, weight, price and terms and conditions in the quotation which is known as the pro forma invoice. 2) Procurement of import license: Every importer needs to have an Import Export Code (IEC) number which can be obtained after getting registered with the Directorate 1 General of Foreign Trade (DGFT) or Regional Import Export Licensing Authority. The IEC number is required to be mentioned in various documents in connection with the import. 3) Obtaining foreign exchange: The importer requires to obtain the currency of the exporter’s country to make 1 payment for the goods imported. For this, Indian currency needs to be exchanged in return for foreign currency. All the transactions involving foreign exchange are regulated by the Exchange Control Department of the Reserve Bank of India (RBI). However, many nations usually accept the US dollar to conduct international transactions. In this regard, banks and many authorised dealers provide foreign exchange. Every importer is required to obtain a sanction of foreign exchange by making an application in the prescribed form to the banks authorised by RBI for issuing foreign exchange. 1 4) Placing order or indent: Once the importer has obtained an import license, it can place an import order or indent requesting the supply of the specific goods required by the importer. This order contains details such as price, size, grade, quality of goods and instructions related to shipping, 1 packing, port of shipment and destination, insurance etc. 5) Obtaining a letter of credit: A letter of credit is obtained by the importer from its bank and then sent to the exporter. It ensures that there will be no non-payment risk www.topperlearning.com 12 from the importer’s side. 1

Ans: 2

7 ([1,2,’3’],’S’,3,4,6) () ‘TEA POTS’ ( 4 * 1/2 =2)

3 a) int('a) produces an error but the following expression having 2 int('a) in it does not return error, why? What is the output produced?

len('a')+2 or int('a')

When logical OR is used in expression – evaluates the first expression - if it is true,it ignores the second expression. -Hence the int('a') is ignored since len('a)+2 is a True value, more than 0 (1 1/2)

Output is 3 (1/2) b) Write a program to input a list of integers and find the difference 3 between the maximum value and minimum value of the integers in the list.

c) Wrtie a program that inputs a string and stores it as words in a 3 tuple. Then translate each word to Pig Latin and print it back as a string.

Eg: if the string is “The quick brown fox”. Then the tuple should be (“The”,”quick”,”brown”,”fox”). To make it in Pig Latin, take the first letter of each word, move it to the end of the word and add “ay” to it. So “The” becomes “heTay”, “quick” becomes “uickqay” ..... The string in Pig Latin should be “Hetay uickqay rownbay oxfay” s=input(“Etner the string”) t=tuple(s.split()) (1/2) nstr=” “ for word in t: nword=word[1:]+word[0]+”ay” (1) nstr+=nword+” “ (1/2) print(“New string is “,nstr) (1)

d) Write a program to input a list of integers. Then create another list 2 with the cumulative sum of the first list. Cumulative sum of list [a,b,c,....] is[a,a+b,a+b+c,...] Eg: if the first list is [2,3,4,5,6,7] then the second list is [2,5,9,14,20,27,..] ie 2,2+3,2+3+4,2+3+4+5,...

ANSWER KEY 1. Monopolistic competition 2. Explicit cost 3. Maximum 4. PPC is downward sloping straight line. 5. Complimentary goods 6. Demand curve for bus travel will shift to the left. It happens because the price of its substitute ( train fare) has decreased , and it will make bus travel relatively expensive. 7. False. The difference between AC & AVC is AFC and AFC can never be constant. Since ATC tends to decline with increase in Q , the difference between AC & AVC must reduce as Q increases. 8. False , this is because in a situation of diminishing returns to a factor MP tends to fall. Fall in MP leads to TP increasing at a decreasing rate. 9. Price discrimination means charging different prices for the same product from different buyers at the same time.. since monopoly is a single seller in the market , it enjoys complete control over the price. In this regard it can follow price discrimination in order to gain maximum profits. 10. © Es>2 11. (b) Monopoly 12. Given Px= 1 Py=2 MUx =2 MUy=2

Equilibrium condition =

Here the consumer is not in equilibrium because

= 2/1> 2/2. The consumer would react to this situation by increasing the consumption of Good X in place of Good Y. 13. DD is the initial demand curve and SS is the initial supply curve. E is the initial equilibrium position where DD intersect SS. Correspondingly OQ is the equilibrium quantity and OP is the equilibrium price. With increase in demand , the demand curve shifts parallelly outwards to D’D’. On the other hand , with increase in supply , the supply curve shifts to S’S’. However, increase in demand is greater than increase in supply. The new equilibrium is at E’ where D’D’ intersect S’S’.So the equilibrioum price has risen to OP, and equilibrium quantity is OQ,. 14. ICDS is launched to improve the overall development of children in India. This would ensure that a healthy labour force is added to the existing stock of man power. Thus , PPC shifts to the right. 15. It is under perfect competition that AR=MR . under perfect competition price is given to a firm as determined by the industry. Constant price implies constant AR and thus AR=MR at all levels of output. Accordingly AR & MR under perfect competition are shown by horizontal straight line. 16.

18. (a) Large no. of buyers and sellers implies no individual sellers can influence the price of the commodity in the market. Any change in output supplied by a single seller will not affect the total output of the industry. To an individual seller the price is given. He can sell whatever output he wants at the given price ie, an individual seller is a price taker. Similarly , no individual buyer can influence the price of the commodity. (b) implication is that any attempt by any firm to charge a higher price than the prevailing market price will fail. The buyers will not pay higher price because they have perfect knowledge . there is no ignorance about factors operating in the market. The seller will not charge a higher price the buyers will not pay a higher price. 19. (a) Availability of close substitute (b) income of consumers (c ) number of uses of the commodity (d) time period. (explain ) 20. In the figure, DD is the market demand curve and SS is the market supply curve. Market Demand and market supply are equal at the point E. At point E OP is the equilibrium price and OQ is the equilibrium quantity. OP is the equilibrium price which is greater than the market price OP,. At the given price, there is excess demand = AB. In reponse to increase in market price , the price of quantity supplied tends to rise leading to an upward movement along the SS curve from point A to Point E. Also a rise in price leads to backward movement along the demand curve from Point B to Point E, indicating fall in quantity demanded. Movement along the Supply and Demand curve will continue to occur till excess demand is eliminated and equilibrium is restored. This occurs at point E , where Market Demand = Market supply.

ENGLISH SAMPLE PAPER GRADE XI Total- 80 Marks SECTION A – READING (20 MARKS) 1. Read the given passage carefully and then answer the questions based on it: [12] Read the passage given below carefully: 12 1. Fear of failure is an attitude problem. All of us postpone things. We procrastinate. We rationalize. We make excuses. We foolishly believe that to be creative and to have a positive attitude and to simply do things, we have to have all kinds of preconditions. 2. You can find several excuses for waiting to be more creative. But scratch the surface of these smooth and logical rationalizations, and if you are honest, you will see the face of a little demon, the fear of failure, hiding there. 3. Zig Ziglar reminds us that this is nothing but an attitude problem: “The future can be depressing or magnificent – it is not correlated to the present or the past, past failures or past successes. It is only our attitude towards these failures or successes which determines our future.” You can change yourself by changing your attitude without fear of error. 4. Problems cause stress and stress reduces our effectiveness. So it is very logical that once we solve our problems, we should be able to increase our efficiency and effectiveness. Incidentally, we can’t eliminate problems unless we have the final exit – the very thought of this itself is very stressful. 5. What causes our problems? Well, roughly speaking one-third of our problems are there because we are alive and kicking. Another one-third of our problems are created by ourselves; and the remaining one-third of our problems exist because of greed and ego. 6. When too many problems are causing you enormous stress and strain, do the following: (i) Think … there must be a better way to solve these problems. It helps to remember the crow and jug story! Recall similar stories and incidents. (ii) Ask, ask, ask…from yourself and from others, how to do things in better ways. May be certain things should not be done at all or should be clubbed with other activities! Don’t forget that even stupid questions will get your intelligent and common-sense answers.

2.Read the following passage carefully: [8] 1 The nine-letter word "interview" can perspire the most knowledgeable and strong people in the world. That may be one reason, political leaders and corporate giants normally do not agree for an interview. But the popular ones, or those who want to make an impact, willingly give interviews. In modern times, whether you like interview or not, your prospects depend on its success. So you must know what an interviewer expects from you. 2 First an academic question. What is an interview? It is a discussion in which an interviewer faces a candidate for a short while and asks questions to probe his knowledge and awareness on the subject. These are done to assess the personality of the interviewee. It is a very formal means of interaction with one person facing a group of persons, each of whom is a specialist in his or her field.

3 Knowledge is an important component of success in an interview. It has two aspects: range and depth. The former implies that you should know a lot beyond your own specialisation and the latter means an awareness of the various aspects of the topics under discussion. An in-depth knowledge is gained through reading and listening. Listening is more important than reading. Be a keen listener, store major facts in your mind and use them at the appropriate time.

4 Next comes appearance, which means your dress for the interview. You must be elegantly attired for the occasion. Wear a simple outfit that suits your physique and features. Women should wear sarees or any other sober dress. Casuals like kurta-pyjama should not feature in your selection of dresses.

5 Conducting yourself in an apt way is equally significant. The way you move yourself, sit on the chair, place your hands and your briefcase and talk to the members reflect your behaviour. Walking sloppily, talking loudly or inaudibly, getting irritated easily, and showing documents insistently are symptoms of bad behaviour. A better way is to enter the room smartly, move forward with dignity, greet the board, sit when asked to, and thank at the end before you leave. 6 Expression is the most important aspect of the interview. It conveys your views and opinions. For good expression, what you need is clarity of mind and speech. Show your balanced thinking to convey your views clearly. 7 Convey your view effectively. In an interview, you may be asked questions where you have to either agree or disagree. Whatever your approach, convince the board that it is unbiased. The board may not agree with your view. Even if you disagree, let not your face show it. Create an impact through your expressions. Give an impression of being a leader. Show that you can cooperate and get cooperation that you can share views and get people to accept your authority to reach decisions and implement them. 8 Finally, never consider yourself to be a perfect man. Being a human being makes you susceptible to flaws. However, try to conform to the highest standards and reach as close to perfection as possible.

(a) Make notes on the above passage in any suitable format. Use recognisable abbreviations wherever necessary and give a title to the passage. (5) (b) Write a summary of the passage based on your notes. (3)

10. Short Answer ques – Any 5 (2x5= 10 marks) a. In the zoo in Lusaka, there is a cage where the notice reads “The world’s most dangerous animal” and inside the cage is a mirror where you can see a reflection of yourself. The point is to make people aware of their destructive nature. People play a vital role in making the world a better place to live in. This notice is a reminder to the people of their evil attitude towards the environment. b. Photographs are memories that are captured and kept for lifetime purposes. Shirley Toulson’s “A Photograph” captures one such moment when her mother was young and she went on a beach holiday with her cousins. Gone are these days of the mother and her cousins but the photograph manages to bring back those memories even after thirty years later. The laughter of the mother while seeing the photograph has become a past incident. But the photograph allows the poet to recall and revive the laughter through the image captured thirty years back. Therefore, photographs are indeed memories. c. Death is something that no one likes to hear about; every human being is scared of this inevitable reality. So, naturally when someone is diagnosed with terminal illness and has only limited number of days, that person and his near and dear ones are not happy at all; they have to accept this reality with pain and sadness. Shahid and his family had to accept the news of his imminent death; Amitav was also shocked. Everyone connected with Shahid was sad. However, Shahid decided to live the remaining numbered days of his life in the best possible manner. Quite frequently half-dozen or more people would gather at his apartment. There would be poetry, talks, singing, and discourses. Shahid would have delicious dishes cooked for his friends. Thus, there was always carnival at his apartment; and he was the center of this carnival. d. French painter Jean Dubuffet challenged the concept of ‘art brut‘ in the 1940s.Before that the art of untrained visionary was of minority interest. At about the same time an untutored genius was creating paradise‘. This was none other than Nek Chand, who cleared a little patch of jungle to make himself a garden sculpted with stone and recycled material is known to the world today as the Rock Garden, at Chandigarh. e. When John Byro saw the boys with the horse he could swear it was his horse tooth for tooth. His eyes told him that it was his horse. However, the fame of the boys‘ family for honesty was known to John Byro and his heart told him that the boys could not have stolen his horse. f. Ranga could never realise that what Shastri told them about his marriage was just a stage managed acting.Shastri did and said what he was tortured to do and say. But Ganga was totally impressed by shastri's productions. They suited him. So he declared that astrology was a science . The Shastra contained greater truth that people imagined.

Tut Value Points ● Mention the curse – death or misfortune to anyone disturbing the mummy ● Damage already caused by Howard Carter to the mummy ● Cooler fan of the CT scan machine suddenly stops working ● Strong winds outside- even nature appears angry ● The general feeling of nervousness among people ● The winds subside once the mummy is placed back in its resting place. ● Findings 112.Albert Ans. This biographical piece first presents Albert in confrontation with his history teacher. When the teacher asks him in what year the Prussians had defeated the French at Waterloo, Albert replies that he did not know and this leads to a heated exchange between them. When he is further asked why he did not try to learn them, he again replies honestly that there is no point in learning dates which could be checked in a book by anyone. This reply angers his teacher greatly who responds asking him again whether he saw no point in learning facts which forms the basis of school education at that time. Albert honestly replies that he did not see any point in learning facts. Now his teacher becomes sarcastic and asks him to tell the class the Einstein theory of education. Ultimately Albert says that he did not see any point in learning dates of battles or which army killed more men but he would be rather interested to know why those soldiers were trying to kill each other. This made his teacher go mad with anger and he scolded Albert viciously and asked him to stay back after school for an extra period. This exchange brings out the honesty of Albert as a child. He of course lacked tactfulness and was very straightforward. He spoke whatever was in his mind. Of course, he used to feel miserable in classes like that of history. His mind was a great mind of science which used to be in search of the true working of the universe and time and other dimensions.

OR Mother’s Day Answer: Value Points: Magic realism is a modern method used in fiction where magical elements are intermixed with the realistic description of everyday affair in such a way that the magical elements are taken as realistic description which help in emphasizing some basic aspect where the writer wants to give focus. Popularized by writers such as Gabriel Garcia Marquez, Salman Rushdie, Milan Kundera etc. In this play, Mrs. Fitzgerald changes her body with Mrs. Pearson, something which is impossible in real life. However, the reader does not object to this fantastic aspect in the plot line because this element has been used in such a way in the plotline that the reader overlooks the impossibility as his real focus is the real issues of the play which is highlighted by the dramatist.

13. The present world population is about 5.7 billion. Every four days the population increases by one million. As incomes rise, health improves and education spreads, fertility rate falls. Development is possible when we limit the population. The rich get richer and the poor produce more babies which makes them turn ever poorer. More children result in more number of unemployed people. If there is no proper system of voluntary family planning then it would most definitely lead to preservation of poverty and degradation of resources. This indicates that unless population control is given the utmost priority, more number of people are likely to die hungry and poor. We must raise awareness in people so that they are capable of choosing between control of population and perpetuation of poverty. Population plays a major role in distorting the future of human society. Hence, it must be checked and controlled for the smooth functioning of the society and for maintaining a balance in the ecosystem. OR Value Points ● Loving, caring, looked after her grandson in the village ● Gave a lot of importance to his education ● Very religious-- went to temple every day, muttered prayers the whole day, sang prayers to her grandson, prayed on her deathbed rather than talking to her family ● Cared for animals—dogs, sparrows ● Uncomplaining by nature—even when she was left alone ● Didn‘t show her disapproval of his new school or his going abroad ● Celebrated his return ● Beauty in her nature and character—serene, caring, calm

Family members can earn income

a. by using their human resources like knowledge, skills, interest etc .for eg.

- By producing vegetables in the kitchen garden

- By doing household chores like cooking, laundering etc

- Teaching children at home instead of sending them for tuition In case these jobs are not done by family members, then they have to spend money on them. This savings become a part of their income

REAL INDIRECT INCOME - commodities and facilities which are available to the family with the use of money or in exchange of goods .

- Services of paid workers

- Barter/exchange of goods

- Fringe benefits – conveyance, housing, medical facilites etc

Barter system

III. 1. What are selection statements? Give one example. (1)

Ans: A set of statements are selected for execution based on the true value of a condition. Eg: if statements

2. What will be the output of the following python statements? (1) x=2 # print(x)

Ans: No output will be generated, as print statement is commented.

3. Differentiate between equality(==) operator and assignment operator? (2)

Ans. Equality operator(==) is used to compare two values and if both values are same then it returns True otherwise it returns False. E.g.: if a==1: #here value of variable is checked to see if it is 1 Print(“the value of A is ”,a)

Assignment operator(=) is used to give a value to a variable. E.g.: a=1 # here variable a is getting a value 1.

Ans: (a) print(s1.replace(“a”, “*”)) (b) print(s1.find(“vo”)) (c) print(“Gre” in s1) (d) print(s1*3)

3. Write python code to allow user input a string. Find the number of vowels in the string. (2)

Ans: w=input(“Enter the String”) vowel=0 for letter in w: if letter in(‘a’, ‘e’, ‘i’, ‘o’, ‘u’): vowel=vowel+1 print(“The number of vowels in ”, w , “is ”, vowel) V. 1. Python lists are mutable. Substantiate this point with example (1)

Ans: A python list is a mutable sequence of values which can be of any type and is indexed by an integer. By mutable, we mean the items in a list can be changed. E.g.: lst=[10,20,30] lst[0]=40 print(lst) Output: [40,20,30] # the item in index zero changed to 40. 2. Pop() and remove() though removes an item in a list works differently. Explain. (2)

Ans: pop() – removes the element from the specified index and also returns the element which was removed. E.g.: lst=[1,2,3,4,5] a=lst.pop(1) # here element at index 1 (i.e. 2 ) is deleted and stored in a. print(lst)

output –[1,3,4,5]

remove() – removes the element specified from the list. E.g.: lst=[1,2,3,4,5] a=lst.remove(1) # here element 1 is deleted. print(lst)

output –[2,3,4,5]

3. Write python script to input a number and count the occurrence of the number in the given list. (2)

Ans: l=[10,20,30,40] num=int(input(“enter the number to be searched in list”)) count=0 for i in l: if num==i: count=count+1 print(“ the element ”, num, “ is present in the list ”, count, “ number of times”)

VI. 1. Why can’t lists be used as keys in a python dictionary? (1)

Ans: Lists cannot be used as keys in dictionary because they are mutable. A Python dictionary can have only keys of immutable types.

2. What are the two ways in which an empty dictionary can be created in python? (1) Ans: Method 1: using the statement d={} Method 2: using dict() E.g.: d=dict()

3. Suppose dict is a dictionary then differentiate following commands: - a)dict.clear b)del dict (1)

Ans: dict.clear() – removes all items in a dictionary. Del dict[key]- removes an item from the dictionary based on the key specified.

4. Create a dictionary to store names of any 5 states as keys and their capitals as values. Also write code to print it. (2)

Ans: dict = {'HP': 'Shimla', 'Punjab’: ‘Chandigarh’, 'Rajasthan': 'Jaipur', ‘Haryana’:’Chandigarh’, ‘MP’:’Bhopal’} print(dict)

VII. 1. Predict the output of the following code: (1) import math print(“MATH FUNCTIONS :”, math.ceil(3.4), math.floor(4.9), math.pow(2,4), math.sqrt(25), sep= “\n”)

Ans: MATH FUNCTIONS : 4 4 16.0 5.0

2. What is the purpose of arange()? (1)

Ans: arange() is used to create an array from a range. It takes a start index, stop index and a step value as arguments. Syntax is =numpy.arange(start index, stop index, step value)

SECTION B

21. Accused and the Right against Self-incrimination The right against self-incrimination is provided under Article 20(3) of the Constitution of India, which stipulates that "No person accused of an offence shall be compelled to be a witness against himself". However, the following restrictions are placed on the exercise of this right: Only such documents/statements are protected as are within the personal knowledge of the accused, and thus records that are maintained in fulfillment of a statutory requirement may not be protected. Further, the accused can be required to give a handwriting sample/blood/DNA sample as the same are not within the 'personal knowledge' of the accused. The protection against Article 20(3) protects the accused only against being compelled to produce documents. The Supreme Court has held that a search and seizure does not amount to 'compulsion to produce' and is thus outside the protection of Article 20(3). Summons under Section 91 CrPC cannot be issued to an accused person, however, a general search warrant under Section 93(1)(c) CrPC is not protected under Article 20(3) of the Constitution of India. 22. Marriage is defined as a social and legal union between a man and a woman; through this institution the spouses create kinship. Kinship is a system of social organization between people who are related by blood, marriage, or adoption. Marriage is a social union because both the spouses are entitled to each other's company and conjugal rights, which are mutual rights and privileges between two individuals that arise from the state of being married. These rights and privileges include affection, companionship, co-habitation, joint property rights, and sexual relations. 23. Inheritance is one of the means of acquisition of property. After the death of the owner, all rights belonging to the deceased with regard to the property are divisible into two classes, namely: (1) Inheritable rights, and (2) Uninheritable rights. A right is inheritable if it survives its owner. It remains functional even after the death of the person to whom it belongs and devolves on his legal representative; it is not inheritable if it dies with his person. Generally speaking, proprietary rights (rights attached to property) like debts are inheritable whereas personal rights (rights associated with the person) are not as they extinguish with the death of the deceased. 24. The third source was the Objectives Resolution adopted in the December 1949 Assembly session. The Constitution derived its spirit from this source. The Objectives Resolution laid down the philosophy and the Constitution expressed it through its many lengthy and detailed provisions. Jawaharlal Nehru, the first Prime Minister of India, had drafted the Objectives Resolution drawing upon the Congress Party documents of the previous two decades. The Objectives Resolution called for the integrity of the Indian Union and that its authority and power were derived from the Indian people. It stated that all the people should be secured with regards to justice, social, economic and political- equality of status, of opportunity, and before the law; freedom of thought, expression, belief, faith, worship, vocation, association and action, subject to law and public morality. Furthermore, the Objectives Resolution provided for adequate safeguards for minorities, depressed and backward classes, and underdeveloped and tribal areas. The Objectives Resolution can be summarized to consist of three interdependent salient features: . 1) protecting and enhancing national unity and integrity; . 2) establishing the institutions and spirit of democracy; and . 3) promoting a social revolution for the betterment of the citizens. 25. LEGISLATION AS A SOURCE OF LAW In modern times, legislation is considered as the most important source of law. The term 'legislation' is derived from the Latin word legis which means 'law' and latum which means "to make" or "set". Therefore, the word 'legislation' means the 'making of law'. The importance of legislation as a source of law can be measured from the fact that it is backed by the authority of the sovereign, and it is directly enacted and recognised by the State. The expression 'legislation' has been used in various senses. It includes every method of law-making. In the strict sense it means laws enacted by the sovereign or any other person or institution authorised by him. Kinds of Legislation The kinds of legislation can be explained as follows: Legislation (i) Supreme Legislation: When the laws are directly enacted by the sovereign, it is considered as supreme legislation. One of the features of Supreme legislation is that, no other authority except the sovereign itself can control or check it. The laws enacted by the British Parliament fall in this category, as the British Parliament is considered as sovereign. The law enacted by the Indian Parliament also falls in the same category. However in India, powers of the Parliament are regulated and controlled by the Constitution, through the laws enacted by it are not under the control of any other legislative body. Subordinate Legislation: Subordinate legislation is a legislation which is made by any authority which is subordinate to the supreme or sovereign authority. It is enacted under the delegated authority of the sovereign. The origin, validity, existence and continuance of such legislation totally depends on the will of the sovereign authority. Subordinate legislation further can be classified into the following types:- Indian Parliament . (a) Autonomous Law: When a group of individuals recognized or incorporated under the law as an autonomous body, is conferred with the power to make rules and regulation, the laws made by such body fall under autonomous law. For instance, laws made by the bodies like Universities, incorporated companies etc. fall in this category of legislation. . (b) Judicial Rules: In some countries, judiciary is conferred with the power to make rules for their administrative procedures. For instance, under the Constitution of India, the Supreme Court and High Courts have been conferred with such kinds of power to regulate procedure and administration. . (c) Local laws: In some countries, local bodies are recognized and conferred with the law-making powers. They are entitled to make bye-laws in their respective jurisdictions. In India, local bodies like Panchayats and Municipal Corporations have been recognized by the Constitution through the 73rd and 74th Constitutional amendments. The rules and bye-laws enacted by them are examples of local laws. . (d) Colonial Law: Laws made by colonial countries for their colonies or the countries controlled by them are known as colonial laws. For a long time, India was governed by the laws passed by the British Parliament. However, as most countries of the world have gained independence from the colonial powers, this legislation is losing its importance and may not be recognized as a kind of legislation. (e) Laws made by the Executive: Laws are supposed to be enacted by the sovereign and the sovereignty may be vested in one authority or it may be distributed among the various organs of the State. In most of the modern States, sovereignty is generally divided among the three organs of the State. The three organs of the State namely legislature, executive and judiciary are vested with three different functions. The prime responsibility of law-making vests with the legislature, while the executive is vested with the responsibility to implement the laws enacted by the legislature. However, the legislature delegates some of its law-making powers to executive organs which are also termed delegated legislation. Delegated legislation is also a class of subordinate legislation. In welfare and modern states, the amount of legislation has increased manifold and it is not possible for legislative bodies to go through all the details of law. Therefore, it deals with only a fundamental part of the legislation and wide discretion has been given to the executive to fill the gaps. This increasing tendency of delegated legislation has been criticized. However, delegated legislation is resorted to, on account of reasons like paucity of time, technicalities of law and emergency. Therefore, delegated legislation is sometimes considered as a necessary evil. 27. Article 326 confers on the citizens of India the right to vote in the general elections to the House of People and to the Legislative Assemblies of States. Every citizen who is not less than 18 years of age (reduced from 21 years by the Constitution(sixty-first Amendment) Act, 1988 and otherwise not disqualified under the Constitution or any other law on the grounds of unsoundness of mind, non- residence, crime or corrupt or illegal practice shall be entitled to be registered as a voter at any such election. There is one general electoral roll for every territorial constituency, as stated in Article 325 of the Constitution, for election to either House of Parliament or to the House or Houses of State Legislature. This Article further specifies that no person shall be ineligible for inclusion to the electoral roll on the grounds only of religion, race caste sex or any of them. Article 331 provides for representation for members of the Anglo-Indian community in the House of People. In the case of Indira Nehru Gandhi v. Raj Narain (AIR 1975 SC 2299), popularly known as Election case, right to free and fair elections has been declared to constitute the Basic Structure of the Constitution. 28. Article 368 of the Constitution provides for constituent powers of the Parliament, and lays down the procedure for amendment of the Constitution. In the exercise of its power of judicial review, the Supreme Court of India in Keshavananda Bharati case (AIR1973 SC 1461) popularly known as Fundamental Right's Case, held that the Parliament in exercise of its amending power under Article 368,could not alter the Basic Structure of the Constitution. Thus the basic structure limits the amending power of the Parliament. The Judges while deciding this case could not form a unanimous opinion on the provisions oftheConstitutionwhichconstituteitsBasicStructure. On a perusal of different cases decided by Supreme Court, the following features seem to emerge as the Basic Structure, so as to be beyond the amending power of the Parliament under Article 368: . Supremacy of the Constitution; . Republic and democratic form of Government; . Secular character of the Constitution and State; . Sovereignty of India; . Judicial Review and jurisdiction of courts under Article 32&Article 226 . Separation of Powers and Independent Judiciary (In the case of State of Biharvs. Bal Mukund Shah (AIR2000SC1296) . Right to Equality and Rule of Law It is, therefore, for the Supreme Court of India to determine finally the essential features constituting the framework of the Constitution. In other words, the Supreme Court has assumed to itself the constituent power in exercise of Judicial Review. In conclusion, the Indian Constitution has not adopted the doctrine of separation of powers in its strict sense. Nevertheless, the Constitution of India has sufficiently differentiated the essential functions of the organs and no organ shall assume to itself what essentially belongs to other. SECTION C 29. Domestic Violence The nature of violence against women varies based on the particular socio-cultural as well as political and economic contexts. It also varies based on spaces where it occurs: public spaces as well as private spaces of family and matrimonial relationships. Domestic violence against women happens in the private space. Domestic violence is largely forbidden in the Western countries. However, in many developing countries, domestic violence is either legally recognized or socially acceptable For example, the United Arab Emirates' laws allow the man the use of limited physical means to discipline his wife and children. Domestic violence is also a socially acceptable practice, including by women themselves, in many developing countries like Jordan, Guinea, Zambia, Sierra Leone, Laos, and Ethiopia. . The salient features of PWDVA are as follows: The PWDVA is a civil law. Its primary objective is to provide compensation as well as support to the woman. This is contrary to criminal law, which intends toprimarilypunishtheperpetrators. Enforcingcriminallawsdependonthe State, the police, and the prosecution lawyer. As a civil law, PWDVA is victim- driven; she has direct access to the court. The rights and reliefs under PWDVA can only be initiated with the consent of the woman. PWDVA describes 'domestic relationships' broadly to include, wives, mothers, sisters, daughters, and live in partners. All of these all are provided protection by the PWDVA.

The protection under the PWDVA is not limited to the matrimonial home but covers 'shared householder' to include mothers, sisters and daughters as well. . PWDVA provides for 'Stop Violence' orders that offer emergency reliefs to stop violence immediately. PWDVA is an additional law and allows women to enforce other laws, such as the divorce laws as well. . For the effective implementation of this law, PWDVA offers both access to justice as well as access to support systems. It provides for Protection Officers to operate as nexus between the court and the woman to ensure accessibility to the justice system. PWDVA also envisages Service Providers, i.e. non- governmental organizations who voluntarily register under the Act, to deliver her with essential support she might require, such as shelter and medical facilities. Service Providers are crucial, as women often would feel more comfortable approaching an NGO rather than the police or state authorities. . PWDVA stipulates for the 'single window clearance system' to aid women in accessing the justice system. This allows woman to use PWDVA to enforce other civil reliefs under other laws as well, such as the criminal law. For example, she can use one PWDVA suit to enforce her right not be dispossessed when a divorce petition is pending (Section 498 A of the Indian Penal Code). This helps her avoid filing of multiple of suits in various forums. . PWDVA provides that the magistrate may, at any stage of the proceedings of the case, direct either one or both the parties to the suit to undertake counseling with any member of the service provides who holds the required qualification and experience of counseling. Women groups are critical to the counseling provision as it is often seen as a tool for preserving marriage and placing the woman back in the violent situation. . PWDVA puts responsibility on the Central and State Governments for training and sensitization of the general public as well as the state authorities including the judiciary. 30. In the first phase between 1772 and 1864, three main developments occurred with respect to the Anglo-Hindu Law. First, the important Dharmashastra texts were compiled and translated by various British administrator-scholars including William Jones, Henry Thomas Colebrooke, J.C.C. Sutherland, and Harry Borrodaile. The rules from these texts were applied to Hindus in order to expand British rule in India. Second, the court pandits were used in the British courts to aid the British judges with the interpretation of the Dharmashastra texts and implementation of the Classical Hindu Law. Third, the court pandits became redundant due to sufficient proliferation and development of established case laws of some precedent value. 31. (i) Supreme Legislation: When the laws are directly enacted by the sovereign, it is considered as supreme legislation. One of the features of Supreme legislation is that, no other authority except the sovereign itself can control or check it. The laws enacted by the British Parliament fall in this category, as the British Parliament is considered as sovereign. The law enacted by the Indian Parliament also falls in the same category. However in India, powers of the Parliament are regulated and controlled by the Constitution, through the laws enacted by it are not under the control of any other legislative body.

Subordinate legislation further can be classified into the following types:- Indian Parliament . (a) Autonomous Law: When a group of individuals recognized or incorporated under the law as an autonomous body, is conferred with the power to make rules and regulation, the laws made by such body fall under autonomous law. For instance, laws made by the bodies like Universities, incorporated companies etc. fall in this category of legislation. .

This increasing tendency of delegated legislation has been criticized. However, delegated legislation is resorted to, on account of reasons like paucity of time, technicalities of law and emergency. Therefore, delegated legislation is sometimes considered as a necessary evil. 32. Rules of intestate succession among Hindus Heirs belonging to a Hindu male are classified into four categories i.e. class I, class II, agnates and cognates. Class I heirs are the most preferred heirs and include mother, wife, son as well as daughter and their descendants upto the third generation. Class II heirs include father, brother as well as sister and their children, maternal and paternal uncles and aunts, maternal and paternal grandfather and grandmother etc. Class II heirs will inherit property only in absence of Class I heirs. If there are no heirs belonging to Class I or Class II then property goes to agnates. When two persons are related by blood or adoption wholly through males, they are called agnates. For example, the son of a great grandson (son, grandson, great grandson being dead) and great grandson of P, SSSS1 is son of SSS and great great grandson of P. Here, SSSS1 is agnate to P as he is tracing relation wholly through males i.e his father (SSS), grandfather (SS), and greatgrandfather (S). No female has intervened in-between. P F FM FMF1 In case, all the above-mentioned heirs i.e. Class I, Class II and agnates are absent then property will go to cognates. When two persons are related by blood or adoption but not wholly through males, they are called cognates. For example father of paternal grandmother i.e. FMF1 is a cognate as female (father's mother) has intervened in between. . Rules of intestate succession among Muslims: There is no codified law for Muslims in the area of succession. They are governed by their religious texts. Among Sunnis, heirs are divided into three categories i.e. sharers (Quranic heirs), residuaries (agnatic heirs), and distant kindred (uterine heirs). Sharers are the most preferred heirs. First of all, sharers are allotted their Quranic shares. If something is left behind after allotting shares to them, then, it goes to residuaries. If their shares exhaust the entire estate, then sharers exclude residuaries and distant kindred. The distant kindred are not entitled to succeed so long as there is any heir belonging to the class of sharers or residuaries. But there is one case in which distant kindred will inherit with the sharer: when there is only one sharer i.e. the wife or husband of the deceased and no other sharer or residuary exist. Among Shias, heirs are divided into two categories i.e. heirs by consanguinity and heirs by marriage i.e. husband and wife. Heirs by consanguinity are further sub-divided into three classes. Class I includes parents and children. Class II includes grandparents, brothers and sisters, and their descendants etc. Class III includes paternal and maternal uncles and aunts of the deceased, and of his parents, grandparents etc. Among the heirs by consanguinity, the first group excludes the second and the second group excludes the third. The claimants in both the categories i.e. heirs by consanguinity and heirs by marriage succeed together, if there are heirs of both the categories.

Rules of intestate succession under the Indian Succession Act, 1925: The Indian Succession Act, 1925 is a central legislation and is applicable to every person, unless and until anyone is governed by any law particularly applicable to them. This Act is not applicable to Hindus and Muslims. Christians and Parsis are governed by this Act. Among Christians, the first preference is given to the spouse of the deceased and his lineal descendants i.e. children, grand children, great grand children or their remoter lineal descendants. When there are no lineal descendants then property passes on to the spouse of the deceased and those who are kindred (consanguinity is the connection or relation of persons descended from the same stock or common ancestor) to him. If there are no lineal descendants or one who is kindred to him, then entire property goes to his or her spouse. In the absence of such spouse, property passes on to lineal descendants or to those who are kindred to him. How it has just been established there are such lineal / kindred descendants! The rules pertaining to interstate succession are more or less same in all the communities. The first preference is given to the husband or wife of the deceased and their lineal descendants. In their absence, the preference is given to collaterals that are close to the deceased. In their absence, property goes to remote agnatic heirs and then to cognatic heirs. A rule of escheat is applicable in all the communities. If no heir is present then property goes to the Government by this Rule. 33. Fundamental Rights The Constitution of India guarantees its people certain basic human rights and freedoms known as 'Fundamental Rights', which are listed in Part- III of the Constitution (Articles 12 to 35.) These are broadly rights of equality (equality before laws and prohibition of discrimination on grounds of religion, race, caste, sex or place of birth; equality of opportunity in matters of public employment; abolition of untouchablility and titles); right to freedom ([rights regarding freedom of speech such as freedom of speech and expression, right to free movement, to form associations, to practice any trade or occupation]; protection in respect to conviction for offences; protection of life and personal liberty; protection against arrest and detention in certain cases); right against exploitation, right to freedom of religion; cultural and education rights and right to constitutional remedies. The right to education was inserted as Article 21A vide the Constitution (eighty-sixth Amendment) Act, 2002. Fundamental Rights stated under Article 14 and 21 are even conferred to non-citizens. The Fundamental Rights guarantee to the people certain basic rights. The legislative and executive actions which infringe upon or violate the Fundamental Rights are declared ultra vires the Constitution. The Supreme Court shall have power to issue directions or orders or writs, including writs in the nature of habeas corpus, mandamus, prohibition, quo warranto and certiorari, whichever may be appropriate, for the enforcement of fundamental rights under Article 32;and the High Courts under Article 226 of the Constitution. The speedy and effective remedy under Article 32 is itself guaranteed as a Fundamental Right. Therefore, these guaranteed rights are termed justiciable rights. SECTION D 34. JUDICIAL PRECEDENT AS A SOURCE OF LAW In simple words, judicial precedent refers to previously decided judgments of the superior courts, such as the High Courts and the Supreme Court, which judges are bound to follow. This binding character of the previously decided cases is important, considering the hierarchy of the courts established by the legal systems of a particular country. In the case of India, this hierarchy has been established by the Constitution of India. Judicial precedent is an important source of law, but it is neither as modern as legislation nor is it as old as custom. It is an important feature of the English legal system as well as of other common law countries which follow the English legal system. In most of the developed legal systems, judiciary is considered to be an important organ of the State. In modern societies, rights are generally conferred on the citizens by legislation and the main function of the judiciary is to adjudicate upon these rights. The judges decide those matters on the basis of the legislations and prevailing custom but while doing so, they also play a creative role by interpreting the law. By this exercise, they lay down new principles and rules which are generally binding on lower courts within a legal system. Given this background, it is important to understand the extent to which the courts are guided by precedents. It is equally important to understand what really constitutes the judicial decision in a case and which part of the decision is actually binding on the lower courts. Judicial decisions can be divided into following two parts: (I) Ratio decidendi (Reason of Decision):'Ratio decidendi' refers to the binding part of a judgment. 'Ratio decidendi' literally means reasons for the decision. It is considered as the general principle which is deduced by the courts from the facts of a particular case. It becomes generally binding on the lower courts in future cases involving similar questions of law. (ii) Obiterdicta(Saidbytheway):An'obiterdictum'referstopartsofjudicialdecisionswhich are general observations of the judge and do not have any binding authority. However, obiter of a higher judiciary is given due consideration by lower courts and has persuasive value. 35. abeas Corpus Mandamus Quowarranto Certiorari Prohibition You may have the body We command By what warrant (or authority)? To be more fully informed To forbid or to stop. Purpose of issue To produce a person who has been detained, whether in prison or in private custody, before a court and to release him/her if such detention is found illegal A command issued by the court to any public or quasi-public legal body that has refused to perform its legal duty. It is an order by a superior court commanding a person or a public authority to do or forbear to do something in the nature of public duty. It is an order issued by the court to prevent a person from holding office to which he is not entitled and to oust him from that office. It is a writ issued by a superior court to an inferior court or body exercising judicial or quasi-judicial powers to remove a suit and adjudicate upon the validity of the proceedings or body exercising judicial or quasi-judicial functions. It is issued by a superior court to an inferior court in order to prevent the inferior court from dealing with a matter over which it has no jurisdiction. The aim of this writ is to keep the inferior courts within the limits of their jurisdiction. 36. Roman Empire The Romans established a form of government - a republic - that inspired several countries for centuries. For instance, government of the United States is hugely is influenced by the Roman model. The Roman State passed through three different periods. The first period was that of the monarchies state. Monarchy was succeeded by a Republic under which civil and military power were in the hands of two consuls who were elected annually. The Patricians controlled the administration. There were struggle between the patricians and plebians for the control of power. Ultimately, both of them got equal political and civil rights. The Republic gave way to the Roman Empire which at one time extended over most parts of Europe, Asia Minor and the whole of the Mediterranean coast. Rome put before the world the ideals of unity, order, universal law and cosmopolitanism. The law of nations developed during this period. Political thinkers like R.G Gettle and historian Edward Gobbin (1737-1794) have attributed the decline of the Roman Empire to reasons such as the sacrifice of individual liberty for the sake of unity, moral depravity of the , failure to make rules for the succession of Emperors, and internal feuds. D. Feudal States They emerged from the long and continuous conflict between the barbarians and the Roman political institutions after the downfall of Roman Empire. Feudalism emerged as a consequence and compromise. Vast territories of disintegrated Rome fell into the hands of powerful nobles. Nobles were the patricians of the Roman Empire, who shared political power with the Monarch. They were the members of families by way of wealth and social prestige. They became high council officials after the decline of the empire. Oriental Empire Nomadic tribes generally settled down in places where their basic needs of food, water and pasture for their cattle were fulfilled. The early nomadic tribes made the valleys of river Ganges and Indus in India, in the valley of Huang Hoangho and Yang Tse-Kiang in China, the Euphrates and Tigris in Mesopotamia and Nile in Egypt as their homelands. Tribal centres became kingdoms and empires by conquests and re-conquests, as in the case of Aryans and Sumerians. Some of the important features of this empire included concept of private property, settlement on definite territorial area, and authority of the eldest member of the family or the person with highest physical force. 37. International Law and Municipal Law and its subdivisions.

It has the large Chaitya-Vihara and is decorated with sculpture and paintings (murals). Ajanta is the only surviving example of the painting of the first century BCE and the fifth century BCE. Major paintings are in cave Nos. 1, 2, 16 and 17. Paintings have a lot of typological variations. Figures in the paintings are heavy like the sculptures of western India. Cave excavation and painting were a simultaneous process and dating of the paintings follows the date of the cave excavation. Almost in all the finished excavations, pictures have been painted, but very few have survived. Various skin colours in the paintings represent multi-coloured society. The themes of the paintings are events from the life of Buddha, the Jatakas and Avadanas. events happened are separated by their locations. Jungle or at palace . Images of Padmapani and Vajrapani are very common in Ajanta. Another important cave site located is Ellora. It is located 100kms away from Ajanta. There are 32 Buddhist, Brahmanical and Jain caves. It is unique art historic site in the country as it has monasteries associated with the three religions dating from fifth century CE onwards to eleventh century CE. Confluence of many styles at one place. There are 12 Buddhist caves having many images belonging to Vajrayana Buddhism. Buddhist caves are big in size and are of a single, double and triple storey. The triple storey of Ellora is a unique one.

Pillar designs grow from Buddhist caves and when they reach Jain caves (9th century CE), they become very ornate and the decorative forms gain heavy protrusion. Most of the caves of Brahamanical faith are dedicated to Shaivism. The different avatars of Vishnu are also depicted here. Cave no.16 is known as Kailas Leni or kailasa temple. It is a rock cut temple which is carved out of a single rock.

It was built in the 8th century CE. The grand sculpture of Ravana attempting to lift Mount Kailash, with his full might is a landmark in Indian art. Elephanta caves and other sites: Elephanta caves located on Elephanta Island near Mumbai were originally a Buddhist site which was later dominated by the shivite faith. It is contemporary with Ellora. The other noteworthy cave site is Bagh located near Indore, MP. The Bagh cave also contains paintings and a painting which represents a group of dancers resembles the Garba Dance of North India (originated in Gujarat). When the early history of the country depends on collective public patronage, the post sixth century CE depends more on political patronage. Cave tradition in Eastern India Like in western India, Buddhist caves have been excavated in eastern India, mainly in the coastal regions of Andhra Pradesh and Odisha. One of the main sites in Andhra Pradesh is Guntapalle in Eluru district. Guntapalle is a unique site where the structural stupas, viharas and the caves are excavated at one place. The other important site is Rampaerrampallam. In Ankapalli, near Vishakapattanam, a huge rock-cut stupa was carved out of the hillock during 4th-5th century CE. It is a unique site as it has the biggest rock cut stupas in the country. Another important cave site is the Udayagiri-Khandagiri caves located in Odisha. These caves are scattered and have inscriptions of Kaharvela Kings, the caves were meant for Jain monks. There are numerous single cell excavations here. The upper part of the cell is decorated with a series of Chaitya arches and narratives that still continue in the folklores of the region.

5. Earliest civilizations found with civic planning – Bronze age – 2500 – 1500 BC – various art forms found were seals, stone sculptures , terracotta figures , gold and pottery. To major cities Harrapa in north and Mohenjadaro in south - roads cut across in 90 deg. Angles - city divided into blocks – drainage system - delineation of human and animal figures were realistic in nature. . Fury and charge on the bull shows detailing on stones 0r clay or bronze metal. – another very important bull picture very often repeated was the Zebu bull - representing the most powerful clan symbolically representing the top officials of Mohenjadaro & Harrapa - cord around the neck – head turning to right – recurring theme in many of rituals and decorative art of Indus – carved on seals with short inscriptions

7

Thousands of seals were found - made of steatite , as well as bronze but most commonly found seals showed – unicorn, rhino, bull, tiger, bison buffalo etc., - for commercial purpose – made as amulets as ID’s - standard size was 2x2 sq inch – found in gold & ivory Depicts a human figure seated crossed legged – elephant & tiger on the right and rhino & buffalo on the left are seen 2 antelopes are seen below , fig has a 3 horned head with inscriptions above. Cire Perdue also known as the lost wax technique – model is made of wax covered with clay – after it is dry wax is melted there is a hole below the mould through which melted bronze metal is poured in after it is cooled clay is removed. Eg. Dancing girl. And Dancing Natraja from Chola Period.

30. Boltzmann's law of equipartition of energy states that the energy of a molecule (gas) is equally partitioned (divided) 1 into different degrees of freedom that the molecule has. The energy per partition (degree of freedom) is equal to 1/2 k T per molecule or 1/2 xRT per mole. T = absolute temperature, k = Boltzmann's constant,

R = Universal gas constant

A diatomic molecule has 5 degree of freedom. 1 Total energy of diatomic gas per mole = Q = 5/2 R T ½ dQ/dT at constant volume = Cv = 5/2 R Cp = Cv + R

In the region from A to B, stress and strain are not proportional. Nevertheless, the body still returns to its original dimension when the load is removed. The point B in the curve is known as yield point (also known as elastic limit) and the corresponding stress is known as yield ½ strength (Sy) of the material. If the load is increased further, the stress developed exceeds the yield strength and strain increases rapidly even for a small change in the stress. The portion of ½ the curve between B and D shows this. When the load is removed, say at some point C between B and D, the body does not regain its original dimension. In this case, even when the stress is zero, the strain is not zero. The material is said to have a permanent set. The deformation is said to be plastic deformation. The point D on the graph is the ultimate tensile strength (Su) of the material. 34.

1.) Time of Flight u = u sin α a = −g v = 0 (at highest point) Now, Using the first equation of motion, ½

v = u + at 0 = u sinα− gt gt = u sinα t = u sinα/g ½

Since t is only half of the total time, therefore we can

calculate total time of the journey as T = 2t, T= [2 u sinα]/g ½ ½ 2.) Maximum Height:

Applying Law of Conservation of Energy,1/2mu² = mgH ½ 1/2 m(u sinα)²= mgH

1/2 mu²sin²α = mgH

H = u²Sin²α/2g

3.) Horizontal Range: ½ Since, the projectile is in the air for a duration T R = u in x direction × T ½ R = u cosα × 2u sinα/g R=u² 2sinα cosα/g ∴ R=u²sin2α/g 36. a)It has two free surfaces. 1 b)As per Bernoulli's principle, atmospheric pressure reduces under the paper.

Let us consider the simple pendulum makes an angular displacement θ as shown in figure. At this position the forces are weight of the bob of pendulum and Tension acting 1 on the string as shown in figure. Let us resolve the weight mg, the gravitational force into two perpendicular components as shown in figure. One component (m g cosθ) is in the direction of tension T that equalizes the tension which is giving necessary centripetal force for circular motion. The other perpendicular component (m g sinθ) is the restoring force acting on the bob to bring to its equilibrium position. 1

The restoring force Fx is written as, Fx = -mgsinθ (-ve sign indicates, the displacement is in opposite direction to force ) for small angular displacement sinθ ≈ θ, hence Fx = -mgθ = - mg (x/L) = -(mg/L)x ...... (1) here we have assumed the displacement x is nearly equal to the arc length Lθ .

Above eqn(1) indicates the restoring force is directly proportional to displacement, hence the oscillatory motion 1 is simple harmonic.

we know that for simple harmonic motion, F = -kx, where k is the force constant and period T of oscillation is given by,

we can see that the bracketed term of the right hand side of equation(1) is the force constant for the simple harmonic motion of pendulam. hence we can write for the period T of simple pendulam as,

Huffington Post India, July 19, 2015, 12.00 am IST Wondering if it’s time to give your child a smartphone. We don’t blame you. It only makes sense that you’d want that kind of 24/7connectivity with your child. But, smartphone use is linked with diminished attention span, sore wrists and disrupted sleep in children. The key to avoiding these problems is mindful use, which requires a level of responsibility and self-control that comes with age. John Breyault, who worked on a study about kids and cell phone use, says, “ ask questions like why does your kid need a cell phone? And ‘ is your teen matured enough to use the phone responsibly and avoid viewing or sending inappropriate content? before buying one". Doctor”Michael Rich, who has studied the impact of media on children extensively says, ‘there is much concerns about overtly harmful activities like cyber bullying. The greatest risk to their long term development and well- being is distraction from real people and experiences. How about benefits? he notes. “If children are guided towards thoughtful, focused and effective use and do not get distracted from more productive experiences, these can be integrated into their lives with minimal risk “. If you have plans to give your kids cell phone, make sure you lay down rules first, if you don’t want them using apps or even texting, make that clear. Parents should first review and agree with their child on what the phone is to be used for, what it is not to be used for and the consequences of unauthorised use. a).Why is peer pressure considered as social pressure? b) How do use of smartphones among teens become a boon or a bane?
