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 don't understand how the compounded reduction of vitamin B1 done by both processes makes the argument by the proponents of irradiation misleading.

Proponents point out :

It might be the case that irradiation reduces B1 levels by 10 % and cooking by 50 % totaling 60 % reduction. That would mean, proponents are right. Irradiation isn't worse than cooking.
The author seems to accept the possibility that proponents would have to be implying that there is no additional reduction of vitamin B1 when products undergo both processes. In other words, the harm done by irradiation, would not be significant since cooking will do much more. Hence, their argument is misleading.

However, there are no grounds for this reasoning of the author, since arguments about both irradiated and cooked products weren't made by the proponents. Furthermore, as the author pointed out, much of the irradiated food is eaten raw, making the possibility of

Don't overlook the word "misleading". The stimulus says that irradiation does not deplete the food of Vit B1 anymore than what cooking does. Okay, but what if the irradiated food is supposed to be cooked and not eaten raw? E says that depletion of Vit. B1 increases as the effect of irradiation and cooking on Vit B1 is additive. This implies that irradiation of food that needs to be cooked makes Vit B1 lower than just irradiated food or just cooked food. So, irradiating certain kinds of foods could make matters worse for Vit B1.
Hence, E it is.

Great explanation.

The key here is to breakdown the last sentence, "However, this fact is either beside the point, since much irradiated food is eaten raw, or else misleading, since _______." An easy way to do this is:

This fact is either:
-beside the point: because much irradiated food is eaten raw

The author is trying to attack proponents of irradiation point, that "irradiation is no worse in this respect than cooking." In the first part of the sentence, he attacked the proponents of irradiated food by saying that much irradiated food is eaten raw. To complete his argument, he must say something about irradiated food that is cooked, thus E is clearly the answer

I too had a hard time understanding it, but after multiple posts and crossing of thoughts, I feel this is the best answer.

Understand this

Proponents say - Irradiated is no worse than cooking. that means, "if" irradiated ( and not cooked ) it will reduce the amount of vitamins from food, and thereby do what normal cooking does to the food.

The option says, "WHAT IF IRRADIATED FOOD HAS TO BE COOKED" ?

DO WE COOK FOOD TWICE TO EAT IT ? NO !

then why should we irradiate and then cook it, if they are doing the same purpose ?

therefore the proponents are missing this valid point where irradiated food has to be cooked as well

therefore irradiation is NOT SIMILAR to cooking. It is a process, which may or may not require cooking.

Case 1 : doesnt require cooking -- beside the point, coz proponents say it is similar to cooking
Case 2 : requires cooking -- misleading coz it will reduce the food even more than "COOKING ALONE" would have done.

Makes sense ?

good explanation..

Answer is E, because according to proponents of irradiation, the latter is no worse than cooking (reducing Vit B1), but "E" states that both cooking and irradiation equally reduce vitamin B1.

This is a tough one.
The idea is to understand that we cannot compare the two methods stated in the argument - Irradiation & cooking.
This is evident from the marker however, .... misleading since _____. So, proponents say that irradiation is no worse than cooking, however ...... misleading bcoz ___?? What could be misleading?? proponents saying that irradiation is no worse than cooking.

A) sooo out of scope
B) is irrelevant to what we are looking for.
C) Trap answer. we are looking for something that is misleading and not details abut cooking and irradiation
D) Again, comparison which we arenot interested in.
E) fits in nice.
"proponents say that irrad. is no worse than cooking, however ... misleading since when you do both the effects of B1 destruction is compounded". Makes sense.

The fact is beside the point SINCE Much of IRR. FOOD is eaten raw.

Since much is EATEN RAW why to compare it with the cooking at first place.

Furthermore , the FACT that IRR is no WORSE than COOKING is misleading because the combined effect of COOKING+IRR. is even worst.

Hi Verbal Experts,
Can you please let me know what should be the proper reasoning for the correct answer E? It appears to me as the best one in the lot because others are wrong!

My question is more on understanding the usage of sentence here..
Does
"this fact is either beside the point, since much irradiated food is eaten raw"
mean that
"the fact is either supporting the point, since much irradiated food is eaten raw"
?

My interpretation of the proponents' counter....
(1) All food is cooked and zapped of its nutrition
(2) Once a food loses its nutrition through one process, there is not much more damage that can be done by the next....(so, whats the harm in irradiation if it just going to be cooked anyhow,,,and because either initial process will have already depleted most of the nutrition, what is the harm in subjecting it to the next?....)

Verbal Experts,

Please dare to explain this one as to why the answer is (E) not through POE but by proper line of reasoning.

I'm not verbal expert.. But let me give a shot at it...

First, I really do think that POE is the best way to approcah this questions. That being said I'll try to justify why E is the answer (After eliminating other choices by POE - since all the other choices are completely irrelevant or too extreme).

There are people who say that irradiation is no worse than cooking or in other words they are saying "You can irradiate your food rather than cook it since both destroy similar amounts of B1 vitamins."

So in effect, they are saying that cooking and irradiation are mutually exclusive processes. Option E addresses this by saying that if both processes are applied on the same food a lot more vitamin B1 is lost.

i.e. For eg : 2 hours of cooking food results in lesser vitamin B1 being destroyed than 1 hour cooking + 1 hour irradiation
