101. 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
