The higher the level of certain vitamins and minerals in the bloodstream, the better a person's lung function, as measured by th
e amount of air the person can expel in one second. The lung function of smokers is significantly worse, on average, than that of nonsmokers. Clearly, therefore, one way for smokers to improve their lung function is for them to increase their intake of food that are rich in these helpful vitamins and minerals.Which of the following is an assumption on which the argument depends.(A) Smokers are less likely than nonsmokers to have diets that are rich in vitamins and minerals.(B) The lung function of smokers whose diets are rich in those vitamins and minerals is generally better than that of nonsmokers with comparable diets.(C) People whose diets are deficient in those vitamins and minerals do not typically have other health problems in addition to diminished lung function.(D) Stopping smoking will not typically improve lung function more than any diet change can.(E) Smoking does not introduce into the body chemicals that prevent the helpful vitamins and minerals from entering the bloodstream.
The correct answer is (E) Smoking does not introduce into the body chemicals that prevent the helpful vitamins and minerals from entering the bloodstream.
Explanation:
The correct answer is (E) Smoking does not introduce into the body chemicals that prevent the helpful vitamins and minerals from entering the bloodstream.
Since the premise that is necessary to take into account is that the higher level of vitamin and minerals in the bloodstream, the better a person's lung function, it would be necessary to consider that the diet can counter the amount of those levels in the bloodstream.
