Scientists have determined that an effective way to lower cholesterol is to eat three servings of whole grains every day. Studies have shown that the cholesterol levels of people who did so were significantly lower after six months than were those of people who did not, even though the cholesterol levels of the two groups were the same before the studies began. Clearly, eating whole grains can have an appreciable effect on cholesterol levels.

The answer to which of the following questions, if true, would be most useful in evaluating the claim about whole grains above?


a) Is it realistic to expect people to eat three servings of whole grains per day?

b) Were the two groups of people in the study involved in the same exercise program?

c) Can the same drop in cholesterol be achieved through medication?

d) Did the study continue to track the subjects beyond six months?

e) Are most consumers aware of the different between whole grains and processed grains?

Personally, I think the answer is definately (B).

But, doesn`t this involve some sort of outside knowlege about exercise being able to lower cholesterol levels??? Exercise isn't stated anywhere in the passage... :?

From a test takers point of view, my guess is (A). It`s the only logical way to link the evidence and the conclusion.

B

This is one of the few CRs where you have to apply your own knowledge outside of the argument.

MATT,

I think only B talks about 2 groups at the same time... all others are out of the ballpark... based on that you don't need any knowledge, but honestly I had a gut feeling about exercise part when I read it :wink:

Agree B is a little bit strange answer

The answer is A, IMO. B clearly requires outside knowledge.

Why is A correct?

If it is not realistic for people to eat 3 servings a day, then the argument falls apart.

I think the denial test is used for assumptions...not everywhere.

Divided on B and A

In exam I would have marked A as it is much more closer to the facts provided.

While evaluating do we always use the answer that mentions both the groups... trying to form a logic...

Well if B using outside info is right then why not C and E... they also use outside info

BTW, I answered B but just trying to critique...
