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: C

------------------------------------------------------------------------------------------------------------

 答案是红色的E我选的是C，我的思路是这样的首先根据however之后我应该判断出这个句子中应该是必须有cooking 和irradiation的对比的，那么这样就剩下CDE。不过这里我也有句话的意思不明白就是the fact is either beside the point这是什么意思啊！还有都已经since much irradiated food is eaten raw了这个irradiated food怎么还cooked阿！问题好像挺傻的，判大家指教

the fact is either...or

当为misleading时，原因才是e

要么离题万里：因为食物本来就是生吃（irradiation后营养流失）

要么误导：因为如果要烹调营养元素流失了2次

可是题目中是对比烹调和irradiation的作用，为什么是两个叠加的作用，为什么不选B呢？谢谢
