roponents 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 _______.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. roponents 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
E. for food that is both irradiated and cooked, the reduction of vitamin B1 associated with either process individually is compounded
我知道意思是用微波以后再烹饪对B1的损失是双倍，但这个答案怎么和需要填空的句子相联系呀？哪位牛人给解释一下？
填空读句子很重要。
填空处是一个转折, however， 重点读转折前一句说，irradiation 的支持者指出 irradiation 在这点上不比烹饪来得糟糕。 往回推一句这点指的是破坏VB1.
只有答案E 是对irradiation和cooking进行了比较，并且讲对vb1的破坏问题，所以选E
