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.
有两个在2到90之间（包含2与90）的整数，主持人请甲和乙两个数字逻辑分析高手猜这两个数。先同时告知甲乙双方：两个数的和大于11、两数的积小于260。再单独告诉甲这两个数的和，单独告诉乙这两个数的积。由甲乙轮流发言，请甲先说。
第一步，甲：我不知道这两个数，但我知道乙也不知道这两个数。
第二步，乙:一开始我不知道之两个数，但知道甲也不知道这两个数：现在我仍然不知道是哪两个数。（乙还有一句话：“无法判断甲现在是否知道是哪两个数”没有说出来。）
