In option C - The fact that the patients couldnt see the benefit now but the doctors recommended them surgery to prevent future heart attacks. Hence, doctors didnt do the surgery for the fees or to practise skills?
GMATNinja @veritaskarishma
Please explain why option C is wrong?
Take another look at the exact wording of (C):
Quote:
C. Most of the patients in the survey decided to undergo coronary bypass surgery because they were advised that the surgery would reduce their risk of future heart attacks.
There are two issues with this answer choice.
First, we know from the passage that "only 75 percent [of patients] benefited from the surgery." There's no time cap on this information -- perhaps they benefitted immediately, or perhaps the surgery prevented a heart attack years down the road.
We're not interested in the doctors' motivations for doing the surgery on these patients (who DID benefit) -- we're interested in the doctors' motivations for operating on the OTHER 25% of patients. Why did doctors operate on this smaller subset of patients? (C) doesn't give us any insight into that question.
Another issue with (C) is that it talks about how doctors convinced patients to get the surgery. But remember that the author doesn't particularly trust these doctors -- he/she thinks that they "were more interested in an opportunity to practice their skills and in their fee[/b] than in helping the patient."
So even if a doctor
tells a patient that the surgery will provide a benefit, that doesn't mean that it actually WILL provide that benefit. It's unlikely that a doctor would tell a patient, "Look, this surgery isn't going to benefit you but I'd really like to practice/collect a fee."
Overall, (C) doesn't undermine the argument that doctors are nefariously doing this surgery on patients who won't benefit.
Compare that with (E):
Quote:
E. The patients who underwent coronary bypass surgery but who did not benefit from it were medically indistinguishable, prior to their surgery, from the patients who did benefit.
(E) says that there is no way of knowing
which patients are going to benefit from the surgery. So the doctors isn't sitting there with the knowledge that a certain patient won't benefit, and then deciding to do the surgery anyway in order to practice/collect a fee. This completely undermines the author's argument.
(E) is the correct answer.
I hope that helps!
