The higher the level of certainvitamins and minerals in the bloodstream, the better a person's lung function, asmeasured by the amount of air the person can expel in one second. The lung functionof 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 increasetheir intake of foods that are rich in these helpful vitamins and minerals. Which of the following is an assumption on whichthis argument depends?

(A) Smokers are less likely than nonsmokers to have diets thatare rich in vitamins and minerals.

(B) The lung function of smokers whose diets are rich in thosevitamins and minerals is generally better than that of nonsmokers with comparablediets.

(C) People whose diets are deficient in those vitamins and mineralsdo not typically have other health problems in addition to diminished lung function.

(D) Stopping smoking will not typically improve lung functionmore than any diet changes can.

(E) Smoking does not introduce into the body chemicals thatprevent the helpful vitamins and minerals from entering the bloodstream.
