Q12:

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 _______.

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

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

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

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

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

选E 还是C. 另外GWD 的答案以有括号的为准吗?  请回答.

E。GWD的答案不少都有问题，有些可以确定是错的，CD上面有修正的答案，还有甜橙等前辈的答案。有些是颇具争议的，要看看讨论，理清思路，自己判断。
