The federal rules aimed at protecting human subjects of medical experiments were established to ensure that patients must be warned of potential risks and an independent panel would evaluate the experiment before it was conducted.
(A) must be warned of potential risks and an independent panel would
(B) must be warned of potential risks and that an independent panel
(C) are warned about potential risks and that an independent panel
(D) will be warned about potential risks and an independent panel would
(E) would be warned of potential risks and that an independent panel would
In this question, I chose C and justified it because rules are present today also and are ensuring both the things as well. So present tense made more sense to me. There is nothing mentioned about rules being not there today and not ensuring. So, C was more concise and hence chose it.PLease Help where I am going wrong?
AndrewN GMATNinja DmitryFarberHello,
pk6969. Choice (C) presents a trap for the unwitting test-taker who does not read and consider the entire sentence. I, too, like the flow of
rules were established to ensure that patients are warned. In isolation, the sentence would work just fine. However, we cannot ignore the parallel marker
and that that prefaces the latter part of the sentence. We need to check for parallelism:
1) The rules were established to ensure
that patients are warned... AND
2) [The rules were established to ensure]
that an independent panel evaluate the experiment
Now, why do the verb tenses not match up? You should keep in mind that the GMAT™ prefers a tight parallel structure whenever possible. A look at (E) shows the difference:
3) The rules were established to ensure
that patients would be warned... AND
4) [The rules were established to ensure]
that an independent panel would evaluate the experiment
In both halves, we get an embedded clause with a subject followed by a verb in the same tense,
would + [infinitive]. There is no real need to evaluate whether
would is the best way of expressing each half. It works, plain and simple, and the parallel elements are consistent, so the answer choice is hard to argue against. (E) is a superior answer to (C).
The way to get the upper hand on even the toughest SC questions is to be cautious. Your goal is not to chase the correct answer, but to get behind the one that is hardest to find fault with. Work from the ground up with fundamentals.
I hope that helps. Thank you for thinking to ask.
