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.  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

这题答案是C/E,为什么A不可以呀？我是这样想的，因为如果那些赞成的人都只关心保持期更长而其实不关心营养问题的话，那这些支持者说它不比煮东东更会损失营养的理由其实是misleading的，

我也倾向于选A. 但众说纷纭, 至今也没有定论.
