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
(B) wings, wings so smooth and so perfectly shaped
(C) wings that are shaped so smooth and perfect
(D) wings, shaped in such a smooth and perfect manner
(E) wings, wings having been shaped smoothly and perfectly so

A, C and E we can get easily eliminated.

Now comes B and D

B and D both are correct.

but B is better because ---

1)It is following Idioms so...that
2) Parallelism.

the clue lies in reading the full question

when we read the full question, we see the word "them". Now if we see them on an underlined portion we are immediately alerted and we look for the antecedent. Here the problem is reversed. We have them in the non-underlined part, so it is our job to make them point to the correct antecedent.

them can refer to any of the following -- aircraft, aircraft manufacturer's and wings.

Clearly them has to point to wings, so we add the extra wing as in B.

Thank you that was the perfect explanation

Good question! Maybe it modifies wings? Or maybe airplanes?

Choice (B) is a better option because it eliminates that ambiguity.

I don't understand how B) is the correct choice.

Quote:
Original: with frictionless wings, shaped so smoothly and perfectly that the air passing over them
B: wings, wings so smooth and so perfectly shaped

Original says that wings are shaped smoothly and shaped perfectly
B says that wings are smooth and perfectly shaped

in my view, B changes the meaning of the original sentence

What is the issue in option D? I think "shaped" is perfectly modifying wings. Please elucidate.

Hello, Parikshit07. If you take for granted that shaped modifies wings instead of airplanes in choice (D), the meaning is still askew. The sentence:

Since the 1930's aircraft manufacturers have tried to build airplanes with frictionless wings, shaped in such a smooth and perfect manner that the air passing over them would not become turbulent.

Notice the conjunction and, without a comma, in smooth and perfect. These are two qualities listed in parallel, not unlike those in the saying high and dry. The problem is, how can anything, wing or airplane, be shaped in a smooth manner? A shape is one quality, a physical quality of appearance, while smooth is another type of quality, one pertaining to touch. The two go together about as well as oil and water, and the lack of clarity in meaning is enough to see off the answer choice.

I hope that helps. If you have further questions, feel free to ask.

Hello, Kunni. Choice (E) suffers from the same problem as the one just mentioned above: shaped smoothly does not make any sense. (I would not invoke the perfect tense either to express what (B) does already in clearer terms.)

(A) wings, shaped so smoothly and perfectly
(B) wings, wings so smooth and so perfectly shaped
(C) wings that are shaped so smooth and perfect
(D) wings, shaped in such a smooth and perfect manner
(E) wings, wings having been shaped smoothly and perfectly so

So, in B 'wings so smooth' is one thing and 'so perfectly shaped' another.?? I see it wrong though. 'Wings so smooth' is aright since smooth is adjective modifying noun.
Would 'so smoothly shaped and so perfectly shaped' OR 'so smoothly and so perfectly shaped' be wrong. ?? where smoothly modifies shaped.

Hello, lnm87. I have addressed your concern above, here. In short, smoothly shaped cannot go together. The adjective smooth is a tactile description, as is its adverbial form; the adjective shaped is a visual description. You can look at something and judge that it may be smooth, but you cannot describe an object as being smoothly shaped. No answer choice but (B) separates the two types of descriptions, a feature that makes (B) the correct answer by default.

I hope that helps. If you have further questions, feel free to ask.

I had gone through that post. Make sense. Marked B wrong for trying to identify whether smooth or smoothly is correct.
For me this is a subtle thing which i was unaware of.

You are not alone in saying that this smooth/smoothly issue is subtle--this is a hard question for a reason, and it forces you to think more about meaning than about parts of speech. I am glad that the question makes sense to you now.

Also, in retrospect i see that had i been little more attentive towards A and D, having already eliminated C and E, i would have eliminated both of them for a straight one reason - modifier issue. That would have made it the most efficient way to eliminate wrong answer choices. Rest POE would have helped me choose B. Aargh..!!

I can't understand why smooth is deployed here instead of smoothly,which is adverb.
I think it should've been adverb.
Please ,experts, correct me and explain deeply if I am wrong

(A) wings, shaped so smoothly and perfectly - Requires Subject to refer to 'that' in the independent clause
(B) wings, wings so smooth and so perfectly shaped - Correct
(C) wings that are shaped so smooth and perfect - should be smoothly and perfectly to modify Shaped
(D) wings, shaped in such a smooth and perfect manner - Subject missing
(E) wings, wings having been shaped smoothly and perfectly so - Having been .. so
