GWD5-Q30:

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

为什么答案是E呢。。有点没看明白这个题的意思
开始说cooking和irradiation的区别，说两个没区别。后来说到however，先说irradiation的食物基本都是生吃，所以支持者说的观点就被削弱了，可是为什么又是however, either beside the point or misleading呢。。这个不是已经misleading了么@@

看到的给讲讲吧

楼主你没有读懂题目，我翻译给你听。括号里的事逻辑思路。
从proponents开始。proponents指出，在这方面，irradiation不比cooking更差了（意思是说cooking更差）。However（注意，这是一个强转折，题中要补充的内容的态度和方向要顺应转折）,事实上either很多irradiated food是生吃的（指与cooking无关，直接否定proponents观点），or或是被误导了，(因为both irradiation & cooking都会减少vitamin B1)，你把irradiated food给cook了，两种作用混在一起了，(你也不知道哪个更差,削弱proponents观点）。
