GWD 7-30

Q30:

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 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 _______.

1. many of the proponents of irradiation are food distributors who gain from food’s having a longer shelf life

2. it is clear that killing bacteria that may be present on food is not the only effect that irradiation has

3. cooking is usually the final step in preparing food for consumption, whereas irradiation serves to ensure a longer shelf life for perishable foods

4. certain kinds of cooking are, in fact, even more destructive of vitamin B1 than carefully controlled irradiation is

5. for food that is both irradiated and cooked, the reduction of vitamin B1 associated with either process individually is compounded

   Answer: E

有哪位NN能不能解释一下,完全没有思路,非常感谢

irradiating=小偷

cooking=强盗

说小偷很坏,有时候比强盗拿的钱还多，但是这是误区，因为要么1）小偷偷过了的地方强盗一般不抢；要么2）小偷和强盗一起来的时候就互相打架不做坏事了

LS太抽象啦.

这是一道争议题,有讨论连接,LZ可以搜一下,答案集中在C和E上.我还是支持E,因为食物毕竟最后还是要用来吃的.
