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


What is your opinion that the 2 sentences create comma splice in Option (B). Ideally , shouldn't there be a semi colon (;) to separate the 2 independent clauses?!

Am I missing something here?

(B) wings, wings so smooth and so perfectly shaped

(C) wings that are shaped so smooth and perfect

Dear AnthonyRitz AjiteshArun DmitryFarber GMATRockstar GMATGuruNY IanStewart GMATNinja VeritasPrepHailey MartyTargetTestPrep,

Why is choice C. wrong?

I think the construction in choice C. is very similar to the OA below:

In the traditional Japanese household, most clothing could BE PACKED FLAT, and so elaborate closet facilities were unnecessary.

Since "BE PACKED FLAT" is right, why is "ARE SHAPED SO SMOOTH and PERFECT" wrong?

Hello, varotkorn. Although I was not named above, I saw your post and felt compelled to help out. I have written a reply on the previous page that explains why shaped + smooth/smoothly will not work. You can read that post here. In short, I think you are focused too much on how a notion is being expressed, rather than on the meaning that is being conveyed.

Good luck with your studies.

Hi varotkorn,

We should a little careful here: not every verb can be followed by an adjective, and I think that is true for shaped and smooth.

The be packed flat example is fine, but it is not possible to follow shaped with smooth. This is just one of those things in English that we need to watch out for. However, as this is an idiomatic issue, we should wait for more opinions on this.

(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


SC58461.01


https://www.nytimes.com/1990/09/11/science/new-plan-wing-design-greatly-cuts-drag-to-save-fuel.html

Since the 1930's aircraft manufacturers have tried to build airplanes with laminar-flow wings, wings so smooth and perfectly shaped that the air passing over them would not become turbulent. The World War II B-24 Liberator bomber and P-51 Mustang fighter had wings designed to maintain laminar flow, but manufacturing imperfections, dents and other inevitable flaws always spoiled laminar flow.



I understand why B is the right answer, however i have following doubt on this option.
wouldn't the clause after comma become an independent clause when the word "wings" is repeated?
In that case shouldn't the 2 clauses either be separated by a semi colon or by a period or are connected by command followed by coordinating conjunction?

Somebody kindly clarify me on this.
Thank you.

Hi omadangopal123, the portion after the comma is not an independent clause. It is (what's called) a resumptive modifier. You can do a Google search for this term, to know more about it.

The structure is:

Phrase (wings so smooth and so perfectly shaped) + Dependent clause (that the air passing over them would not become turbulent)

Grammatically, such structures function as phrases.

p.s. Our book EducationAisle Sentence Correction Nirvana discusses Clauses, their application and examples in significant detail. If you or someone is interested, PM me your email-id; I can mail the corresponding section.
