Got it wrong in first go!

only B & C are compelling options!
this question is checking concept of "resumptive modifiers", which demands repartition of word "wings"
Also, option C could have been right provided we had perfectly; only adverbs can modify verb (verb = shaped). perfect is adjective. Further, "shaped smoothly" would have been wrong. you can shape perfectly, but not smoothly. In B this is corrected; wings so smooth (adjective) and perfectly (adverb) shaped
. . so answer is B

Now, What are RESUMPTIVE MODIFIERS;read below

By adding modifying phrases to the end of a sentence, a writer can take the reader in new, sometimes unexpected directions. A resumptive modifier picks up a word or phrase from a sentence that seems to be finished and then adds information and takes the reader into new territory of thought. Because resumptive modifiers are, by nature, repetitive, they tend also to add a sense of rhythm to a sentence.

Example: The Swiss watchmakers' failure to capitalize on the invention of the digital timepiece was both astonishing and alarmingastonishing in that the Swiss had, since the beginnings of the industrial revolution in Europe, been among the first to capitalize on technical innovations, alarming in that a tremendous industrial potential had been lost to their chief competitors, the watchmakers of Japan.

for TWO MORE EXAMPLES of this type of question, search following questions in forum
"Yellow jackets number among the 900 or so species . . . "
"In a crowded, acquisitive world, the disapperance of lifestyles such as those once . . ."

(C): Adverbs are typically "-ly", so anything that looks like "shaped so smooth" is incorrect. Eliminated.

(A), (D): The sentence must make clear what was shaped, the planes or the wings. Choices A and D leave this ambiguous, which you know daddy GMAC would never allow. Eliminated.

(B) vs (E): Both are grammatically correct, however, (B) is the better choice since (E) uses a passive voice ("having been"). Also, there is a standard construction "so x, and so y, that z", which (B) employs.

brandy,

(C) cannot be correct since it says "shaped so smooth" instead of "shaped so smoothly".

A smooth [noun]. (as an adjective)
To [verb] smoothly. (as an adverb)

'shaped so smoothly' does not sound logical. a shape can be perfect or artistic. a surface can be smooth, but IMO a shape can't be smooth.

so, the problem with A is that it isn't logically structured.

A n D (past participles) wrongly modifies the aircraft manufacturers so incorrect
E redundancy error
out of B n C
in C Relative clause + relative clause is occurring (with THAT)
so B is the winner.

Why not, this seems quite an apt SC question. Once again, the GMAT isn't 'always' about the logic, sometimes it can also be about the less error prone. Experts, am I right or not?

Hi mohnish

Some basic grammar backgrounds
1. VERB-ed modifier + comma ==> Always modifies a preceding clause.
2. Noun + Noun modifier ==> Can modify preceding noun, any noun in the preceding clause or preceding clause.
3. Idiom: so X that Y

Back to the question.

Since the 1930's aircraft manufacturers have tried to build airplanes with frictionless wings, shaped so smoothly and perfectly that the air passing over them would not become turbulent.

(A) wings, shaped so smoothly and perfectly
Wrong. Verb-ed modifer "shaped" + comma ==> modifies preceding clause ==> it's like aircraft manufactures are shaped.... ==> Wrong.

(B) wings, wings so smooth and so perfectly shaped
Correct. "wings" is NOT redundant at all. This is "noun + noun modifier" ==> Modifies preceding noun "wings" very clearly.

(C) wings that are shaped so smooth and perfect
Wrong. "smooth" and perfect" are ADJECTIVE. But we need adverbs here ==? shaped smoothly and perfectly.

(D) wings, shaped in such a smooth and perfect manner
Wrong. Same error as in A.

(E) wings, wings having been shaped smoothly and perfectly so
Wrong. the usage of "so that" = in order to. But it's not the case here.

Hope it helps.

As per e-gmat, noun +comma+ ed modifier modifies preceding noun and here ed modifier is modifying wings not the entire clause or subject.

Hope it helps.

I dont get it....why is everyone favouring usage of wings two times....
Shaped is a , verb-ed modifier...it modifies preceding noun or noun clause which in this case is wings.
Perfectly and smoothly are adverbs hence option A is correct.

Can anyone point out the flaws in my logic ??

verb-ed modifier always modify proceeding noun, comma or without comma does not matter. A is choice not wrong because of verb-ed modifier, It is wrong because of the meaning. In not underlined portion, them is used which refers to wings or airplane, which is confusing. hence we define wings again to make the clarity.
