651. 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

Solution:

Pronouns

After coma, “wings” is required because pronoun “them” is present towards the end of the sentence.
For pronoun “them” a clear antecedent is needed. This antecedent will be “wings” which must be placed after coma.
Hence, A, C, and D are incorrect. Moreover in C, instead of adverbs (smoothly and perfectly) adjectives (smooth and perfect) have been used.
Furthermore in D, “smooth and perfect manner” mean “smoothly and perfectly” hence, D is wordier by one word than the sentence was required.
E is wordy.
B is the best choice.
