I have two questions here.

1. Someone said that what follows after "as" in B is a clause while it is not so in C. Please correct me if i'm wrong but "because of Y" and "the result of Y" are both prepositional phrases right?

2. If the above is true, then why are they not logically parallel? I mean why is repetition of "because of" preferred over "the result of"

Hello, ravigupta2912. I agree with the excellent analysis IanStewart has provided above. I do not like to fall back on idiomatic constructs to derive an answer, but we cannot ignore the not so much [A] part in the non-underlined portion: we need an as to complete that comparison. Only (B) and (C) use the keyword in question, but (B) does, in fact present a problem. If we keep in mind that as is to be used as the parallel marker, we get a nonsensical comparison. Compare (B) to (C):

(B) [science moves forward not so much] because of the insights of great thinkers AS
[science moves forward] the result of more mundane developments...

(C) [science moves forward not so much] because of the insights of great thinkers AS
[science moves forward] because of more mundane developments...

(C) is a clear winner. To answer your questions, what follows as in both (B) and (C) is a phrase. Finally, concerning parallelism, the GMAT™ prefers it any time to a non-parallel construct. This split presents a bigger issue, but that is to be expected, since parallelism is not a primary concern on SC questions. (It is more of a secondary or even tertiary concern.)

I hope that helps. I know I was beaten to the punch, but I thought I would chime in, nonetheless.

Thanks Andrew. I think I am realising that when in doubt, just repeat the entity in comparison. Now when you repeat it, C just sounds absurd.

But to understand it further (and thank you for the patience in answering my very stupid questions), if we add "as" prior to "result of" (removing "the" in "the result of"), it would make more sense. But why is that? I mean what is the role the 2nd "as" plays in this case?

(I'm thinking in terms of helping verb and main verb but this isn't a verb phrase, so i'm failing to complete the whole explanation and logic in my head.)

Once again, I think IanStewart has already provided an answer: as a result of is an idiomatic phrase, one that serves in a similar explanatory capacity as because of. In a different sentence that did not employ the not so much [X] as [Y] construct, as a result of might work perfectly. Here, though, the as is pulling double duty when it cannot handle the grammatical load.

Confused by the usage of "because of" - i thought it could only modify verbs.
Is "because of" modifying "moving forward" or "the insights of great thinkers"?

"Because of" is used to provide reasons for actions. Here, the action is "moving forward" and hence the use of because is correct.

Eg - The game got delayed because of traffic.
- The game's delay was due to traffic.

In the above examples the split is not between the actual reason, but the action/noun that you're giving the reason for.

Sentence Analysis



An argument of some historians is presented. The argument compares the reasons for the development of science. The smaller reason is the insights of great thinkers, and the bigger reason is more mundane developments such as improved tools and technologies.

The sentence has an error: “not so… but” is incorrect. To present a comparison, we need to use “not so…as” construction. “Not X but Y” construction is used when we want to discard X and accept Y, not to present a graded comparison. The “so much” after “not” is a clear indicator that a comparison is being made in this sentence.

Let’s consider the following two sentences:
1. Bob is not intelligent but caring.
2. Bob is not so much intelligent as caring.

The first sentence says that Bob is not intelligent and that Bob is caring. On the other hand, the second sentence compares the magnitude of how intelligent and how caring Bob is. This is the difference between “not X but Y” and “not so much X as Y” structures.


Option Analysis

A. because of the insights of great thinkers but because of
Incorrect. For the reason mentioned above.

B. because of the insights of great thinkers as the result of
Incorrect. This option lacks parallelism. While “not so” is followed by a clause (which can modify the verb “moves”), “as” is followed by a noun phrase “the result” (which cannot even modify the verb “moves”).

C. because of the insights of great thinkers as because of
Correct.

D. through the insights of great thinkers but through
Incorrect. For the following reasons:
1. The error of the original sentence
2. The phrase “through the insights” cannot idiomatically modify “moves”. We don’t say “science moves through the insights”.

E. through the insights of great thinkers but result from
Incorrect. For the following reasons:
1. The error of the original sentence.
2. The second error of option D
3. The verb phrase “result from” cannot modify the verb “moves”


Great explanation, kudos to you! GMATIntensive

sunny91 If we read A as using the idiom "NOT x BUT y," then our x and y are "so much because of . . . " and "because of." The "so much" in x would ruin the parallelism. However, if we read "NOT SO MUCH" as the first parallel marker, then we can use "AS" to introduce a parallel second part.

Hi DmitryFarber,

I can see that in A, the part after NOT has additional phrase 'so much' while the part after BUT does not, but Does GMAC always requires that perfect parallel? I mean Will A be correct if we don't have option C? Thank you.

First, a general answer to your question: Any time you ask, "If it weren't for the right answer, would this answer be right?" you are suggesting that there are two right answers, and we simply want to pick the nicest one. Fortunately, the GMAT doesn't tend to do that, because then the answers would be subjective. What do *I* think is a good way to say it? Generally, the four wrong answers are wrong. On rare occasions, one answer might seem okay but just a bit unclear, and then another choice is clearer, but this is rare. Run with the assumption that the four wrong versions are all identifiably bad, and then go back and identify all those flaws. You'll learn much more from each question!

As for my earlier discussion of A, I was just explaining why A would still not be parallel under that interpretation. However, the interpretation we were discussing was not correct, so even if it were parallel, we wouldn't want to read the sentence that way. The structure is definitely "no so much X as Y," so A has the wrong idiom ("not so much X but Y").

In formal writing, we use ‘so … as’ in negative connotations and ‘as… as’ in affirmative contexts.
Examples for so…as.
Tom is not so smart as Dick is
GRE is not so difficult as GMAT is
Child prodigies are marked not so much by their skills as by the fact that these skills are fully developed at a very early age.
Examples for as…as
Sita is as bold as Gita
An inventory equal to 90 days sales is as much as even the strongest businesses carry

Thanks Daagh for detailed explanation. This really helps...

(A) because of the insights of great thinkers but because of
THe right idiomatic usage is so .....much as therefore out

(B) because of the insights of great thinkers as the result of
'because of ' better conveys the meaning therefore out

(C) because of the insights of great thinkers as because of
THe meaning is perfect along with the idiomatic usage as so.....much as

(D) through the insights of great thinkers but through
Similar reasoning as A

(E) through the insights of great thinkers but result from
Similar reasoning as A

"Because of" usually used with a clause is being used with a noun
Should we take that into consideration while solving ?
