标题: 问一道GWD逻辑题 [打印本页] 作者: xiaowei0804 时间: 2010-10-30 15:01 标题: 问一道GWD逻辑题 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 B1 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 food’s 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 food for 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 B1 than carefully controlled irradiation is E. for food that is both irradiated and cooked, the reduction of vitamin B1 associated with either process individually is compounded
为啥是E?作者: zhangyunkai5 时间: 2010-10-30 16:09
This fact is misleading指的是irradition不比cooking差这个事实(意思就是在毁坏营养元素方面)是misleading A 支持者是什么样的人(无关) B 杀菌不是irradiation唯一的影响(无关) 说的是irradiation的影响有哪些 C cooking是准备食物的最后一步 irradition是为了保证食物怎么样 也没有说到营养元素的事 D 某种特定的cooking怎么样 原文没说过的事 范围不对 E 只有E在说两种方式对VB1的毁坏问题 考试时直接选E了 解释:irradiate和cook在毁坏VB1上的作用是复合的 单独比较没有意义 另外food is......也把food is eaten raw没有说到的情况给说了作者: xiaowei0804 时间: 2010-10-30 22:58
