I was hesitating for a while and finally ended up selecting E. After reading the prompt about 3 times, answer E was the most logical answer. The argument suggests that both irradiation and cooking have the same detrimental effect on vitamin B1. With the facts presented in statement E, this argument becomes misleading since it never mentions the possibility of the damage to B1 being compounded.

Hard to explain sorry.

IMO E.

My observation:- Since the overall contents of this question are long, chances are that the answer choice will be an easy one.

In such cases, it is advisable to read the answers as quick as possible.

gonna go with E on this one.

you double the reduction of vitamin b with irradiation...

ex. 90% of vitamins are destroyed when cooked or irradiated.
plant b has 100mg of vitamin b.
after irradiation: 10mg
after cooking: 1mg

This is very good question.
Argument states that irradiation destroys b1.
coking does the same.

however, irradiated food eatten raw. so irradiation and cooking will have compunded impact in reducing b1.

IMO E

Tough question because of negative structure. IMO: E is correct.

I think the conclusion should be: "Cooking destroys vitamin B1 more than irradiation does" is NOT correct. So every answer that does not have information regarding the reduction of vitamin B1 is out of scope.

(A) many of the proponents of irradiation are food distributors who gain from food’s having a longer shelf life --> OUT because there is nothing about the reduction of vitamin B1.

(B) it is clear that killing bacteria that may be present on food is not the only effect that irradiation has --> OUT because the author does not talk about the effect.

(C) cooking is usually the final step in preparing food for consumption, whereas irradiation serves to ensure a longer shelf life for perishable foods --> maybe right, but it just says that cooking is the final step. No information regarding the reduction of vitamin B1 --> OUT

(D) certain kinds of cooking are, in fact, even more destructive of vitamin B1 than carefully controlled irradiation is --> OUT because it is the opposite answer.

(E) for food that is both irradiated and cooked, the reduction of vitamin B1 associated with either process individually is compounded --> CORRECT because it says that for food that is both irradiated and cooked, the reduction of vitamin B1 = the reduction by irradiation + the reduction by cooking, not only by cooking. Hence, the above comparison is not valid.
