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 are 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, sinc_____________________

(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 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 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

请大神帮我看一下E选项是什么意思吧，我看不懂啊，呜呜呜。。。

非大牛。
E选项大概是说对于又被irradiated（暂且理解为微波吧）又被cooked的食

物来说，造成维他命B1减少的原因是复合的。也就是说，你怎么知道对这样

的食物而言是cooking造成维他命减少呢？
作者要驳斥之前提出的微波至少不比cooking坏的态度，也就是对cooking是

正态度，由此可排除D。
