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
正确答案是E
我不太理解reasoning中说：
By stating that irridation destroys no more b1 than cookjing does, the proponent seems to be suggesting that any food that is going to be cooked might as well be irradiated because it will end up with the same amount of b1 either way.里的逻辑关系。
我觉得这句是说分别cooked和irradiated消耗的b1一样，那么这和答案e-二者加起来消耗更多b1这个假设不是不搭么？
我觉得pro的观点主要强调了，cook也会导致B1减少，而且情况只会比irr严重，（所以irr的损害不大）。结论的后半段认为，pro的观点会误导大家（也就是错的）。E选项中说明：因为当食物同时需要irr 和cook的时候，会对B1造成比两者单独存在时候更大的损伤，也就是说，如果没有irr的话，单独cook的损伤是比两者复合更少的。这个明显是对pro的攻击，也就是支持了结论。

compound：柯林斯字典动词第六条：

同意楼上的，我一开始也选C。补充一下现在我觉得C错的理由。正如OG上解释的，C说的是cooking是最后一个步骤，irradiation是为了对perishable foods更长时间的保鲜。这两个分别是cooking和irradiation的作用。跟哪个好哪个不好没有关系。没有起到misleading的作用。作者: ET游戏狂 时间: 2013-9-26 10:49
这种题目用中文考我觉得一大半人都能做对...
