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 _______.
99. 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 Bl 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 (A) many of the proponents of irradiation are food distributors who gain from foods' having a longer shelf life (B) it is clear that killing bacteria that may be present on food is not the only effect that irradiation has (C) cooking is usually the final step in preparing food for consumption, whereas irradiation serves to ensure a longer shelf life for perishable foods (D) certain kinds of cooking are, in fact, even more destructive of vitamin Bl than carefully controlled irradiation is (E) for food that is both irradiated and cooked, the reduction of vitamin Bl associated with either process individually is compounded
either beside the point,如何跑偏?就是本来不需要cook的food,现在却用irradiation处理和cook处理来比较,这就是since后面的意思。 or else misleading,如何误导?脚着就应该和either后面的思考方式相联系,就是本来需要cook的food,即便现在再来一道irradiation处理,也不会干掉超过本来纯粹cook处理干掉的B1数量(因为irradiation处理干掉的B1不会比cook处理干掉的多)。但是since这两种处理相结合的话实际上干掉的B1数量是可以求和的(也即compounded表达的意思)。 呃希望说清楚了。。
