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

I will go with A. Last 4 options goes much beyond what is stated so can be ignored safely.

OA is E, but I'm really confusing why not C.
I think the two parts connected by “either…or…” are close related, and therefore can be put together(integrated) to strengthen the author’s point. For example, we can say:
… However, this fact is both beside the point and misleading, since irradiated food is eaten raw, and irradiation serves to ensure a longer shelf life for perishable foods while cooking is usually the final step in preparing food for consumption.
How do you think about this line of thinking?
Maybe it’s a bit awkward and not so convincing. Let me try again.
Using C, we can switch the two parties following “either” and “or” without changing the meaning and the flow of the argument—
… However, this fact is either misleading, since much irradiated food is eaten raw, or else beside the point, since “cooking is usually the final step in preparing food for consumption, whereas irradiation serves to ensure a longer shelf life for perishable foods”.
Using E in the place of C in above sentences, on the other hand, would seem to be either intrusive ( coming out of nowhere) or too far-reaching.
Open to discussion...

Hello,
I was also bit confused abt the answer choice but after some careful observation i realised the answer to be E.
Here goes my explanation.
the author is trying to disprove the point that irradiation does the same damage as cooking does to the food.
the fist point he says is Most of the irradiated is raw. hence, cooking doesnt come into picture here and we cannot say that irradiation does the same damage as cooking does to the food.
and now the second point also needs to prove similar point.
Option C says that " for food that is both irradiated and cooked, the reduction of vitamin B1 associated with either process individually is compounded" i.e the loss more vitamins by cooking the irradiated food than by cooking food thats normal.
So, the point that both the processes do the same damage is misleading here as irradiation causes the loss to multiply when cooked.
get back to me if any futher doubts..
regds,
Kiran

THX, Kiran, thx for ur explaination. But, I'm sorry, I have to argue against your reasoning. I agree the author's ponit is to refute that irradiation and cooking do same damage to foods. But, I think, in the last sentence, the author just want to attact the proponent's line of reasoning in the sentence: "Proponents of irradiation point out that irradiation is no worse in this respect than cooking." I do agree with you about your explaination to the first part of the last sentence. The author point out irradiated food can be eaten withou cooking. Then, the proponents can not say irradiation is no worse than cooking. Here, I think the author point out the first logic flaw in the proponents' reasoning. Option C is: "cooking is usually the final step in preparing food for consumption, whereas irradiation serves to ensure a longer shelf life for perishable foods".In this option, I think the author found the second logic flaw in the proponent's reasoning. The proponent simply differentiate two steps of making food, while illogically assert that irradiation is no worse than cooking. However, different step dosent necessary bring out different degree. Then, it's misleading... I think it's a very funny question, although it is somewhat puzzling. Anyway, OA is the boss and OA is E...

Option E is merely stating a fact or inferring the argument.
Irradiation +cooking compounds the elimination of vitamins in the food.
I do not see how the above sentence misleads the arg's point.
The answer should be C .
