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 n
（E）for food that is both irradiated and cooked, the reduction of vitamin B1 associated with either process individually is compounded
题目分析：A说很多支持irradiation的人是那些由于食物有更长保鲜期而从中获益的分发商，没提过。杀。B说irradiation的作用不仅仅是杀细菌，原文反复谈的就是irradiation和cooking对于杀细菌的作用，范围不对，杀。C说cook是做饭的最后一步而irradiation能确保食物保鲜期更长，扯，杀。D说cooking比irradiation更能毁坏维他命，有关系，但是不能驳斥原文，与原文方向一样了，杀。E有点看不懂，但反复说的就是cook和irradiation对于毁坏维他命的作用，与原文谈的一致，选这个。
