今天听说一个逻辑题 说的是营养学家关于irradiation的好处坏处的 营养学家的研究都是什么什么赞助的 于是他们出的报告什么的 ~求考古 -- by 会员 214mike (2012/9/21 7:45:58)
不知道你说的是不是一道填空题~~~~~~是OG上的原题 答案E Which of the following most logically completes the
argument?
The irradiation of food kills bacteria and thus retards spoilage. However, it also lowers the nutritional value of many foods. For example, irradiation destroys a significant percentage of whatever vitamin Bl a food may contain. Proponents of irradiation point out that irradiation is no worse in this respect than cooking.
However, this fact is either beside the point, since much irradiated food is eaten raw, or else misleading,
since
(A) many of the proponents of irradiation are food distributors who gain from foods' having a longer shelf life
(B) it is clear that killing bacteria that may be present on food is not the only effect that irradiation has
(C) cooking is usually the final step in preparing foodfor consumption, whereas irradiation serves to ensure a longer shelf life for perishable foods
(D) certain kinds of cooking are, in fact, even more destructive of vitamin Bl than carefully controlled irradiation is
E)for food that is both irradiated and cooked, the reduction of vitamin Bl associated with either process individually is compounded-- by 会员 完整人生Lydia (2012/9/21 18:02:19)
