Read the passage and answer the questions with complete sentences. (2 points each)</p><p>A team of scientists did an experiment to try to find out the effect that fluorinated water had on tooth decay. The dentists divided a large group of people into 4 different groups. Group 1 was given 10% fluorinated water. Group 2 was given 20% fluorinated water. Group 3 was given 30% fluorinated water. A 4th group was given unfluorinated water. The dentists expected the group that was given 10% fluorinated water to have the least number of cavities. The teeth of all groups were examined before and after the 12 week experiment. The results were as follows:</p><p>10 % fluorinated water group 3 cavities 20 % fluorinated water group 1 cavity 30 % fluorinated water group 5 cavities Unfluorinated water group 9 cavities</p><p>1.
