og12 cr99题没有明白题目解释啊，为什么说cooking和radiation一起能减少更多的VB1就是削弱了原题啊？为什么选E啊?
99. Which of the following most logically completes theargument?

The irradiation of food kills bacteria and thus retardsspoilage. However, it also lowers the nutritional valueof many foods. For example, irradiation destroys asignificant percentage of whatever vitamin B1 a foodmay contain. Proponents of irradiation point out thatirradiation is no worse in this respect than cooking
.However, this fact is either beside the point, sincemuch irradiated food is eaten raw, or else misleading,since .
(Amany of the proponents of irradiation are fooddistributors who gain from foods’ having alonger shelf life

(B) it is clear that killing bacteria that may bepresent on food is not the only effect that

irradiation has

(C]cooking is usually the final step in preparing foodfor consumption, whereas irradiation serves toensure a longer shelf life for perishable foods

(D) certain kinds of cooking are, in fact, even moredestructive of vitamin B1 than carefullycontrolled irradiation is

(E)for food that is both irradiated and cooked, thereduction of vitamin B1 associated with eitherprocess individually is compoundedE

这题..cook导致损失的Vb1也不比radiation损失的VB1少，所以radiation就无关紧要

了？肯定不是阿，你本来就radiation了，损失了一大半，再拿去做菜，又损失了一大半，

都没Vb1了！！所以radiation损失＝cook损失不能说明radiation无所谓,radiation还

是很害人的..

我觉得这道题你要用排除法做，
A：题里讲的是IRRADIATION 和 COOKING 哪个损失营养多，和PROPONENTS是谁无关
B: IRRADIATION 还有除了杀菌以外的功效和减不减少B1无关
C: 我一开始选的是这道题，后来想想，COOKING和IRRADIATION的目的不一样，并不影响他们是否减少食品的B1含量，无关
D： 这个加强了PROPONENTS的观点
E：有谈到了IRRADIATION和COOKING也谈到了REDUCTION OF B1和题目相关性最大，
正面想的话我还没想出来，我觉得你好好研究一下原文的意思，
