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 _______.

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.  roponents 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
为什么是E呢

A:说支持者是利益相关者,因而人家的观点misleading,涉及主观攻击;错(如果题目是 or else subjective, since_  我认为还沾边);
B:只是把题干里的出了杀菌防腐,还可以破坏营养重述了一遍而已;
C:C是这道题我认为最容易错选的选项,似乎阐述了一个cooking 和 irradiation的区别。但是请注意:
     支持者说 irradiation并没有比cooking在破坏营养方面更严重,言下之意,就是对于eventually要cooked的食材,反正都要cooking被破坏,先irradiate一下也无妨。(注意这句话更提示了支持者默认食材都要cooked:“However,this fact is either beside the point, since much irradiated food is eaten raw”)
      所以C说cook是最终环节,而irradiate只是为了在货架上存放时间长,并不影响支持者的“反正都要Cook”这个思路;
D 把certain kinds of cooking和carefully controlled irradiation做对比,这个极端并不说明问题;
E;对于irradiate后也要cook的食物,这两个环节Vb减少的影响是叠加的; 所以即使ir<cooking,也不好。故misleading。所以E正确。
