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...
