Premise: According to a recent study, advertisements in medical journals often contain misleading information about the effectiveness and safety of new prescription drugs.
Conclusion: The medical researchers who wrote the study concluded that the advertisements could result in doctors’ prescribing inappropriate drugs to their patients.

The researchers’ conclusion would be most strengthened if which of the following were true?

(A) Advertisements for new prescription drugs are an important source of revenue for medical journals. Off-topic

(B) Editors of medical journals are often unable to evaluate the claims made in advertisements for new prescription drugs. Off-topic

(C) Doctors rely on the advertisements as a source of information about new prescription drugs. This statement increases the likelyhood that doctors would prescribe drugs on the basis of advertisement information. This is it.

(D) Advertisements for new prescription drugs are typically less accurate than medical journal articles evaluating those same drugs. Off-topic

(E) The Food and Drug Administration, the government agency responsible for drug regulation, reviews
Although this may be true by itself, there is no direct indication that the FDA influences doctors' decision on prescription drug choice, as far as the argument is concerned. Beside, statement (C) above does more to strengthen the conclusion.

C for me as well

Try to negate option (C) the entire argument falls apart.

Hence (C) is the correct answer !!

This question is a prime candidate for pre-thinking the answer. Clearly the underlying assumption itself is that doctors rely on ads to prescribe medicines which is what would most strengthen the argument.

B is a trap b/c in gmat800, there is a question using the similar pattern; B turns out to be the right answer. In that question, B is an assumption proving that one party is responsible for something.
Here, B is wrong b/c of "often".

KAPLAN OFFICIAL EXPLANATION:

C

In the question we're asked to strengthen the researchers' alarming conclusion that the misinformation they've discovered in journal advertisements could lead doctors into misprescribing drugs. This argument works only if we assume that doctors give credence to the ads. Since the best way to strengthen on argument is to confirm the truth of an assumption, we want a choice that says doctors are indeed influenced by the information in the ads. According to (C), doctors use the ads as a serious resource for information about new prescription drugs. So (C) is correct. (A) indicates the ads are important to publishers as a source of revenue, but does nothing to show that the ads are important to doctors, let alone that they can affect doctors' prescriptions.

(B) and (D) support the notion that the ads are or can be misleading: (B) tells us that journal editors often can't tell whether an ad is deceptive; (D) tells us that ads are usually less accurate than articles evaluating the drugs. But we already know that the ads contain misleading information, so these choices add nothing. (E) weakens the argument by suggesting that a government agency is watching out for potentially harmful, misleading claims.
