标题: OG 13 101
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 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破坏的 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

可以排除bcd,a是说为啥misleading而不是怎么misleading
可是不明白为啥e说reduction是两者的叠加就对了...
求解释
