标题: PUZZLED!!!!HELP
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
i
t 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
为什么C是错的，。。。。。

irradiation作用就是杀菌并不能烧熟食物。而cooking可以烧熟。
文章说他误导了人，拿irradiation 和cooking两种方式比较了VB的剩余量，从而说irradiation和cooking没什么不好好的。

但比较法的前提是参照物物在同一基础上，我们才能比较。也就说比较的东西要都是生的，或都是熟的。这样才能比。因此说他误导了人。而放到同一基础上比较的结果就是辐照过的而且烧熟的食物 VB大大减少。

C选项其实也不错。但我觉得针对 misleading 这个字眼，即要从支持辐照者的逻辑上来攻击它，C选项有点间接。。因此选E

我自己的一点看法。。不知道能被接受不。。。
