Dear anurag16,

I'm happy to respond. :-)

First, a little constructive criticism. I think this this color is exceedingly hard to see, so it would be best not to use it for anything you want seen.

If you think of the GMAT SC as a test of grammar, then the GMAT will trap you on question after question. The GMAT SC tests grammar, logic, and rhetoric all together, and SC mastery involves understanding the interplay of those three strands. If you focus exclusively on grammar, you will be lost on most of the harder questions. Here, you are making an argument about why (B) is grammatically correct. Of course (B) is grammatically correct---and that's precisely besides the point!

In this question, (B) is 100% grammatically correct, but it is not a good answer. Let's think about this. We are talking about uses of something. The most efficient way would be to say:
Castor oil was used as X, Y, and Z.
For whatever reason, the author wanted to highlight the contrast between the use as a "laxative" (something they put inside their bodies) with the other external uses. The author creates this contrast with the "not only . . . but also" structure. Thus,
Castor oil was used not only as a laxative, but also as Y and as Z.
That's still very elegant, and this is exactly what (C) does.
By contrast, (B) introduces a new clause for the third factoid, rather than simply include it on the same list. That's enormously clunky! New clauses should introduce something genuinely new, something that opens new logical ground. Why start an entire new independent clause for a single item that simply could be added to a list? That's an astonishingly poor rhetorical choice! There's no sense of elegance and style. This version is an absolute embarrassment compared to (C).

What's particularly tricky about this question is that the prompt also makes the same rhetorically disastrous choice, so this might make (B) appear not too bad. I am sure many GMAT takers focused exclusively on grammar fell for the trap of (B). Meanwhile, the hyper-literalist would see the change in (C) and think that's a "change in meaning," rather than simply the first appearance of high quality writing among the answer choices. These official questions are brilliant, and they are crafted at a very sophisticated level. The student who focuses purely on grammar will not fare well on these questions.

Does all this make sense?
Mike :-)

i marked option B.For me even though gramaticaly C was correct bt changes the meaning which is illogical.It says for sliding giant stone blocks castor oil serve as a laxative, skin softeing solution and constructon lubricant.This is totally illogical.

B seems correct because second clause mention another use of castor oil and first clause talks about uses in term of laxative and external use.

what is wrong with option B.sometime hard to understand what gmac is trying to do

Dear CorporateFinancier,

I'm happy to respond. :-)

In the "not only . . . but also" structure, a comma is not necessary. It would used for organization of the first branch of the parallelism were particularly long. Here, the first branch is simply a small prepositional phrase "as a laxative," so the comma would be superfluous. Also, keep in mind, the GMAT does not test punctuation: no SC answer choice will be wrong purely on the basis of punctuation.

Does this make sense?

Thanks, though for instance in this question - https://gmatclub.com/forum/next-month-s ... l#p1867854 - option C is eliminated on the basis of punctuation, as far as I understand:

Next month, state wildlife officials are scheduled to take over the job of increasing the wolf population in the federally designated recovery area, the number of which will however ultimately be dictated by the number of prey in the area.

A. area, the number of which will however
B. area; the size of the population, however, will
C. area, however the number of wolves will
D. area; the number of which will, however,
E. area, when the size of the population will, however,

Hi Mike,

Please correct me if I am wrong but is option B wrong only because a new clause is added for the 3rd fact? Is that something that GMAT tests as oppose to option C ?

Dear pra1785,

I'm happy to respond. :-)

I would say that, by turning the third element in the list into its own clause, (B) became quite awkward, and answer choices that sound awkward are wrong on the GMAT. The GMAT definitely has a ear for the rhetorical fitness of the answer choices. I would discourage you from trying to formulate a mathematical black & white rule about this, because it's as much a matter of "feel" as anything else.

As you may have heard me say before, you can't arrive at GMAT SC mastery by assembling some collection of rules. You have to develop a "feel" for how the language sounds, and the only way for a non-native to hone this sense is by developing an assiduous habit of reading. See:
How to Improve Your GMAT Verbal Score

Does this make sense?

Thanks, though for instance in this question - https://gmatclub.com/forum/next-month-s ... l#p1867854 - option C is eliminated on the basis of punctuation, as far as I understand:

Next month, state wildlife officials are scheduled to take over the job of increasing the wolf population in the federally designated recovery area, the number of which will however ultimately be dictated by the number of prey in the area.

A. area, the number of which will however
B. area; the size of the population, however, will
C. area, however the number of wolves will
D. area; the number of which will, however,
E. area, when the size of the population will, however,


Hello,

Trying to help here...

I think what mikemcgarry said was punctuation itself does not make an option correct or incorrect, but the meaning does. When punctuation changes the meaning, so, because of the change in meaning, a choice can be correct or not.

In the example above, using comma makes the next clause refers to/explain the previous word (in this case, area). Letter A: 'the number of which' refers to 'area'....That's why is incorrect, because 'the number' is referring to area, something clearly awkward.

On the other side, using semi-colon separates two independent clauses (Letter C) giving the correct meaning: two independent information about the same theme.

Best,

why b is wrong.
gmat test grammar and meaning. just two things. simple.
grammatical error is easy to find. but meaning error is hard

if we dont see grammar error, find meaning error.

using our common sense of this world (seem a phrase in a novel), we find meaning error.
castol oil is not , can not be, construction lubricant. it serve as a construction oil.
simple, b is wrong.

am i correct?
