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

By POE, I agree with the OA. However, I have this doubt:
Although it seems a strengthen question, this is a weaken question because we have to show that the point of the proponents of irradiation is wrong.
In this sense, we have to weaken the conclusion: "irradiation is no worse in this respect than cooking". In other words, we have to show that irradiation destroys a higher percentage of vitamin B1.
Choice E indicates that irradiating and cooking the food destroys more vitamin B1 than either of those processes alone. However, this choice just shows that the compound effect is bigger or higher, it doesn't show that irradiating is worse than cooking if we comparing them individually.

Please, your help.

Hi metallicafan,

The proponents conclusion isn't that irradiation is "no worse than cooking." The proponents conclusion is that irradiation is good and beneficial, a claim that they support with the evidence that irradiation is no worse than cooking. Our task is to complete the author's argument--how can we weaken the assumption linking the proponents evidence to their conclusion? (E) does exactly that, pointing out that even if irradiating and cooking are comparable, doing both is worse than either alone!

I am still not clear with the structure. Someone please clear my doubt as in how are we arriving at the answer?

Thanks in advance. :)

Thank you expert,
I fail this question because I do not realize the conclusion covered. I do not know what I look for in the answer choices.
- conclusion: radiation is good
- evidence: radiation only harm as cooking do

prethink: look for something which shows that radiation is bad. E match.

many questions in gmatprep make us unable to realize the conclusion and we fail soon. do you have any advise for us in this situation. expert?
