Critical Reasoning

One Zydol capsule contains twice the pain
reliever found in regular aspirin. A consumer will
have to take two aspirin in order to get the relief
provided by one Zydol. And since a bottle of
Zydol costs the same as a bottle of regular
aspirin, consumers can be expected to switch to
Zydol.

Which of the following, if true, would most
weaken the argument that consumers will be
discontinuing the use of regular aspirin and
switching to Zydol?

(A) A regular bottle of aspirin contains more
than twice as many capsules as does a
bottle of Zydol.
(B) The pain reliever in Zydol is essentially the
same pain reliever found in regular aspirin.
(C) Some headache sufferers experience a
brief period of dizziness shortly after
taking Zydol but not after taking regular
aspirin.
(D) Neither regular aspirin nor Zydol is as
effective in the relief of serious pain as
are drugs available only by prescription.
(E) A Zydol capsule is twice as large as the
average aspirin.


Can some one please explain why E is wrong...

The statement says that one Zydol provide same effect as two aspirin, so the size of Zydol is not important. The right answer should be A

As per question, 2 aspirin is equal to one zydol.

2 aspirin is equal to one zydol: the question means effect not size, which is out of scope.

P1. One Zydol - twice the pain reliever found in regular asprin
P2. A consumer will have to take two aspirins to get the relief provided by one Zydol.
P3. A bottle of Zydol costs the same as a bottle of regular asprirn.

Conclusion: consumers can be expected to switch to Zydol.

A attacks the argument in the right way.

For S, W, A questions, the following answer is attractive but wrong

1. IRRELEVANT to evidence
2, RESTATE evidence
3, CONTRADICT evidence
4, STILL NOT CORRECT for qualifying words

the main point of S,W,A question and of CR is to make us

1.accept evidence
2,understand how evidence goes to conclusion.

come back to the question

E is STILL NOT CORRECT.
C is IRRELEVANT to evidence
B is RESTATE evidence

A perfectly attcck the conclusion by proving one capsule of aspirin still cheaper than one capsule of zydol.
So A is the ans

yes the answer in A,
but considering C as faroff is a grave mistake... GMAT does prop up with answers which could seem vague.
