What is the answer? I’m not finding this website to be helpful and am getting the impression that it is not a reliable source for information, but more a clearing house for email addresses.
Can you convince me otherwise?

thanks admin
to using.. in C doesnt seem correct to me.
Please guide.

I do not think C is correct either…”to using” is against basic grammar rules. Take GMAT team…plz clarify..
Same here. In C ‘to using’ does not seem grammatically right. I would choose option B, which looks best. Take GMAT team..Please clarify.
SARVA..B also has “to developing”./…all options seem to be wrong…TAKE GMAT TEAM please clarify…this is completely misleading
In GMAT, we have to choose the best answer not the right answer.
Hence, I think the answer is C.

Ans for the above q is C
C
Reasoning:
This is a most common construct among the many GMAT questions that I have seen over couple of months. “Not Only…. But also” is the trick here.. Needless to explain, there is no other ans choice using this construct.

its definitely C

I would still go with B…can some pls give an explanation as to why B is wrong.
In C I do not find the wordings correct..I feel “not only” has been displaced a bit
C is the correct answer . The option C makes use of construct “not only.. but also” ,which is correct on GMAT .
To me , Option B seems to be wrong .
Since “and” is used we can try separating these as :
There are any number of skilled freelancers who can develop strategy and create marketing materials with a keen eye for using proven methods
There are any number of skilled freelancers who can develop strategy and create marketing materials with a keen eye to developing new and innovative techniques
Now since “with a keen eye” is associated with both these sentences , it should have either a “for” at both places or an infintive “to”.
Option B uses both “for” and “to” which is incorrect
Option C solves this problem by using “to” at both places.
These are just my views.I may be wrong.
Take GMAT team please guide.
c is correct answer
