151) Benton City residents have adopted healthier lifestyles. A recent survey of city residents shows that the eating habits of city residents conform more closely to government nutritional recommendations than they did ten years ago. During those ten years, local sales of food products containing kiran, a substance that a scientific study has shown reduces cholesterol, have increased fourfold, while sales of sulia, a food rarely eaten by the healthiest residents, have declined dramatically. Because of these positive changes in the eating habits of Benton City residents, we predict that the obesity rate in the city will soon be well below the national average.

Write a response in which you discuss what questions would need to be answered in order to decide whether the prediction and the argument on which it is based are reasonable. Be sure to explain how the answers to these questions would help to evaluate the prediction.

claim:  the obesity rate in the city will soon be well below the national average.
data:1.the increasement of local sales of food products containing kiran
        2.the sales of sulia, a food rarely eaten by the healthiest residents, have reduced
Warrant: citizens eat more healthy food and less unheathy food.

Intro
According to a recent survey, the Benton citizens’ eating habits are more close to the government healthy suggestion than before. Given the fact that some positive changes of eating habits were kept, the writer argues that the obesity rate in Benton will decrease and be below the native average rate. Many assumptions are put forward in this argument, but it should be proved to strengthen this argument.

Middle
First, the conclusion come from a recent survey, but there is no data to show how many people join this survey which loses the reliability. Second, the writer believed that the increased sales of the food including kiran which decline the cholesterol indicated more citizens change to healthy life style. However, such a fact does not necessarily imply healthiness. It may be not only good for reducing the cholesterol but the cheaper price. Then, another assumption is the reduction of sulia, because of the reduction in heathiest citizens. There is no evidence to prove sulia is unfavorable to people and what kind of people buy it. In conclusion, it not adequate to obtain this argument.
