Consumer advocate: In some countries, certain produce is routinely irradiated with gamma rays in order to extend shelf life. There are, however, good reasons to avoid irradiated foods. First, they are exposed to the radioactive substances that produce the gamma rays. Second, irradiation can reduce the vitamin content of fresh foods, leaving behind harmful chemical residues. Third, irradiation spawns unique radiolytic products that cause serious health problems, including cancer.
Each of the following, if true, weakens the consumer advocate’s argument EXCEPT:
(A) Unique radiolytic products have seldom been found in any irradiated food.
(B) Cancer and other serious health problems have many causes that are unrelated to radioactive substances and gamma rays.
(C) A study showed that irradiation leaves the vitamin content of virtually all fruits and vegetables unchanged.
(D) The amount of harmful chemicals found in irradiated foods is less than the amount that occurs naturally in most kinds of foods.
(E) A study showed that the cancer rate is no higher among people who eat irradiated food than among those who do not.

A weakens the statement by giving additional information concerning the probability to find radioactive residues on the fruits.
However, statement B deals with the causes of cancer and does not address the original statement in any way.
As this answer choice is unrelated to the original statement it cannot be weakening it.
Hence, B is the answer we are looking for.
Hope this helps.
Best regards,
Chris

So as to arrive at the answer let us start by finding the weakeners and then we can eliminate those weakeners,leaving the right answer.
(A) Unique radiolytic products have seldom been found in any irradiated food. : That gives us a reason not avoid the products.weakener
(B) Cancer and other serious health problems have many causes that are unrelated to radioactive substances and gamma rays. Irrlevant to our discussion.we are not here to find out the causes of those health problems.
(C) A study showed that irradiation leaves the vitamin content of virtually all fruits and vegetables unchanged. This attacks one of the reasons why we should avoid the product.So it is a weakener.
(D) The amount of harmful chemicals found in irradiated foods is less than the amount that occurs naturally in most kinds of foods. So this food is better than most of the foods.So why do we avoid it ? Weakener
(E) A study showed that the cancer rate is no higher among people who eat irradiated food than among those who do not. Just like in option C, this attacks a reason to avoid,making us like the product more.So weakener.
Answer is B
