The usage of colon at the start of the underlined portion gives us a hint that what follows is going to be a "
list" with multiple parts. We know that all the parts of the list must be parallel, so just by keeping that in mind, we can eliminate C/D/E right off the start. They are mixing up "
infinitives" with "
particples".
Between
(A) and
(B), I had hard time choosing one over other. I initially chose (A) in 01:10 mins for its
neat and
clean parallelism maintained between all the infinitives starting from the first infinitive (to abolish) in the non-underlined portion of the sentence. It also, keeps the list after the colon in the form:
not to X, but to Y. Here, X too has a list with three items (
reduce it, ameliorate it, disincentivize it). I would have loved if this list had an "and" before the last item, but none of the answer choices have it, so I think that's the style author chose to keep. But, I think an OG question would keep it prettier. So, (A) looks good enough.
No?In (B), however, I could not find any meaning error or parallelism error. The list after the "colon" consists of parallel "participles" (
not reducing it, ameliorating it, disincentivizing it, but simply abolishing it). In case it's confusing what does this
"it" in the list refer to- the answer is
"THE use of fossil fuels". Some may argue that the
"participles (verb-ings)" in the list are not parallel with the the first infinitive (to abolish) in the non-underlined portion of the sentence, but do we really need them to be parallel to
"to abolish"? In my opinion,
no. So, I could not find any solid reason to eliminate (B) and choose it over (A). So, I vote for the both. Either one of them could be correct, so lets wait for the OA for the big reveal.
So, if I have to choose one, how would I do that? Lets try and compare both side by side by substituting the referent of "it" in (A) and (B).
(A).......... the only way to halt global warming is to abolish the use of fossil fuels: not to reduce the use of fossil fuels, ameliorate the use of fossil fuels, disincentivize the use of fossil fuels, but to simply abolish the use of fossil fuels.
(B).......... the only way to halt global warming is to abolish the use of fossil fuels: not reducing the use of fossil fuels, ameliorating the use of fossil fuels, disincentivizing the use of fossil fuels, but simply abolishing the use of fossil fuels
To me,
(B) sounds better. But, (A) is not horribly bad either. To explain why, see this sentence below:
To get a good score in GMAT, you need to study: not making excuses, finding shortcuts, or hoping for things to happen, but studying earnestly.
This is so better than this-
To get a good score in GMAT, you need to study: not to make excuses, to find shortcuts, or to hope for things to happen, but to study earnestly.
I don't think an actual GMAT question would ever put a test taker in this situation, but as far this question is concerned, I am choosing
(B) over (A) because it sounds good to me. And this is one of the many dreaded ways that can hurt you horribly if applied blindly in OG questions as GMAT sometimes punishes hardly for choosing stuff based on just how they "sound".
