The irradiation of food kills bacteria andthus retards spoilage.  However, it alsolowers the nutritional value of many foods. For example, irradiation destroys a significant percentage of whatevervitamin B1 a food may contain. Proponents of irradiation point out that irradiation is no worse in thisrespect than cooking.  However, this factis either beside the point, since much irradiated food is eaten raw, or elsemisleading, since _______.



A.   manyof the proponents of irradiation are food distributors who gain from food’shaving a longer shelf life

B.   itis clear that killing bacteria that may be present on food is not the onlyeffect that irradiation has

C.   cookingis usually the final step in preparing food for consumption, whereasirradiation serves to ensure a longer shelf life for perishable foods

D.   certainkinds of cooking are, in fact, even more destructive of vitamin B1 thancarefully controlled irradiation is

E.    forfood that is both irradiated and cooked, the reduction of vitamin B1 associatedwith either process individually is compounded




答案是E, 可是不明白哪里MISLEADING了呢?

先分析这个句子,这个观点(Proponents of irradiation 的观点)在irr食物都是生吃的的前提下是离题的(无用的),那在什么情况下是错误的呢?在必须熟吃irr食物的情况下   而cook  irr食物,这时候减少量会加剧,两个过程都会损失vb    那么就证明irr是不好的,不可取的,因为此时cook是必须的过程,我们只能选择放弃irr过程
