GMATNinjaCan you please provide explanation for this question. I was confused between B and C.
Let's compare (B) and (C):
Check out the noun modifier in (C): "... that are shaped so smooth and perfect..." - does this modify "wings" or "airplanes"? Notice that it could technically modifier either one. (If you're wondering why it can modifier "airplanes," check out
this article, particularly usage #4.
In (B), we don't have that ambiguity. The word "wings" is repeated, so we know without a doubt that "so smooth and so perfectly shaped" modifies "wings". That gives us one solid vote in favor of (B) over (C).
Also, "so smooth and perfect..." is trying to give us more information about
how the wings are
shaped -- so we'd actually want to use adverbs here (i.e. "smoothly and perfectly"), not adjectives ("smooth and perfect").
Lastly, notice that in (B), the wings are "so smooth," but in (C), the wings are "
shaped so smooth..." -- what exactly does it mean to be "
shaped so smooth(ly)"? Aren't we just trying to say that the wings are
smooth? This is a minor point, but the modifier is more direct and clear in (B).
That gives you enough reason to pick (B) over (C)!
