Anandnk, you are twisting my arm! :beatup

A) "shaped so smoothly..." is a dependent clause with no subject
B) correctly introduces the dependent clause with the subject "wings"
C) "smooth and perfect" are adjectives. We need adverbs "smoothly and perfectly" in order to modify verb "shaped"
D) again, the dependent clause is introduced with no subject or pronoun (ie which or that) which refers to the subject of the independent clause
E) to convey the idea of magnitude, "so" should have been placed before the adverbs which intend to modify the verb "shaped". Also, use of present perfect is unappropriate

Dharmin,Anand

you are correct. but lets set a trend ourselves. When i was taking my GMAT, i used to attempt to explain most ,if not all, of my answers, right or wrong. let us try to promote this culture. Anand does a great job, but we want others to explain their answers too.

Here the absolute phrase starting with "shaped" needs to clearly identify what is shaped...wings are shaped OR airplanes are shaped.

Only B and E fit that criteria. It wouldnt be hard to eliminate E.

B is so much better and concise.

I agree it is not hard to choose between (B) and (E), but I was looking for second best choice, and I think (A) fits the criteria very well. Because in (A) "shaped" is modifying its nearest noun "wings", which is correct isn't it.

Any comments will be of great help?

"shaped so smoothly..." is a dependent clause with no subject? U can trace this to obvious subject wing mentioned in this sentence, can you not? Or B is correct because "shaped SMOOTHLY" is unidiomatic?

A)
Dependent clause: "shaped so smoothly and perfectly that the air passing over them would not become turbulent"

Above statement, as a stand alone phrase does not make sense because it has no subject(or rather, object). What is shaped so smoothly and perfectly...? What does "them" refer to?

I am not sure why the part after comma is not considered a modifier modifying wings.
Now consdiering this to be case of resumptive modifier one can chose B as a straight answer.
However, can one explain what is wrong with my previous logic? Does one need subject in the modifier?

airplanes or wings need to be in second clause to remove ambiguity. B seems to be clearer

Another question to add to Saurya's , Can it be treated as a modifier? Doesn't it modify wings? can somebody throw some light into this?

Also can you really have something smoothly shaped? Wouldn't you have to seperate smooth and perfectly shaped for the sentence to actually make sense?...Don't know if this was asked...

I looked into this one again and I believe the reason why A is not as good as B is simply because the relative pronoun "them" at the end of the sentence does not have any clear referrent. Does it refer to "airplanes" or "wings"? The same goes for A's participial phrase form which could refer to either one of those 2 preceding nouns.

For example, you have these 2 participial phrase structures:
eg The airplane kit model in the closet, built with such perfection that it amazed the whole family, was part of his collection.

As you can see above, there is an ambiguity as to what was built with such perfection. Is it the subject of the prepositional phrase in red or is it the "airplane kit model"? Because of this ambiguity, relative pronoun "it" also have an ambiguous referrent. If the author meant that it was the closet which was built with..., then he should repeat the word closet to clear such ambiguity. By the same token, "it" should then have a clear referrent.

eg The airplane kit model in the closet, a closet built with such perfection that it amazed the whole family, was part of his collection.

You can apply this same concept to the original question

I missed this post.

I have a doubt in (B) and (C). :roll:

Both (B) and (C) have "so smooth", then why it is wrong in (C) but not in (B).

I got my answer.
Such a silly question :wall .

In (B), "smooth" and "shaped" (adjectives) are modifying Noun (wings). So it is right.
In (C), "smooth" and "perfect" (adjectives) are modifying Verb (shaped) but we know that only Adverbs can modify Verb. So it is wrong.
