GWD5-Q30:
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 _______.
A)many of the proponents of irradiation are food distributors who gain from
food’s 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 B1
than carefully controlled irradiation is
E)for food that is both irradiated and cooked, the reduction of vitamin B1
associated with either process individually is compounded
為什麼答案是E不是C呢?? >"<
