No worries. These items can be pretty tricky to spot when there is so much going on in the sentence. I'm glad I could be of some help.

Agree with C. Both "did not emerge" and "developed" are parallel in the construction "not X but Y".

Rest of the choices have either parallelism errors or passive constructions.

VeritasPrepKarishma:

Is the use of had correct in option choice D, because there is already a word in past perfect tense, so had can be used??
Please guide me on this.

[quote="amostofi1999"]The reams of studies and drafts documented by Gustave Eiffel indicate that the design of the Eiffel Tower generally emerged not in a rapid manner but developed painstakingly from multiple trial prototypes.

(A) emerged not in a rapid manner but developed painstakingly
(B) emerged not in a rapid manner but was painstakingly developed
(C) did not emerge in a rapid manner but developed painstakingly
(D) did not emerge in a rapid manner but had painstakingly developed
(E) did not emerge in a rapid manner but it was painstakingly developed

emerged not in..........but developed.......not parallel

same prob in b

did........emerged

did...had...not parallel

it.......pronoun error in E

hope it helps....

The reams of studies and drafts documented by Gustave Eiffel indicate that the design of the Eiffel Tower generally emerged not in a rapid manner but developed painstakingly from multiple trial prototypes.

(A) emerged not in a rapid manner but developed painstakingly - parallelism issue - Not X, but Y - X and Y need to be parallel
(B) emerged not in a rapid manner but was painstakingly developed - parallelism issue -
(C) did not emerge in a rapid manner but developed painstakingly - Correct
(D) did not emerge in a rapid manner but had painstakingly developed - parallelism issue
(E) did not emerge in a rapid manner but it was painstakingly developed - parallelism issue - usage of it disrupts parallelism, also emerge is not parallel to was developed

Answer C

since the idiom not X but Y is used, the parallel must be maintained.

doesnt the ending of non underlined part " generally " followed by "did not" pose a structural error and awkwardness?

Aditya, hi,
Could you kindly elucidate on the structural error you have indicated about generally and did not?
If there was an error in the copycat version, then even the OA in the official question should be wrong. Will an official question have an error in the OA?

I'm not challenging the OA sir, in fact, I'm talking about the original question, not the one you posted.
The reams of studies and drafts documented by Gustave Eiffel indicate that the design of the Eiffel Towergenerally did not emerge in.... but developed painstakingly from multiple trial prototypes.

doesnt the highlighted portion sound structurally wrong?

The reams of studies and drafts documented by Gustave Eiffel indicate that the design of the Eiffel Tower generally emerged not in a rapid manner but developed incrementally from multiple trial prototypes.
A. emerged not in a rapid manner but developed incrementally
B. emerged not in a rapid manner but was incrementally developed
C. did not emerge in a rapid manner but developed incrementally
D. did not emerge in a rapid manner but had incrementally developed
E. did not emerge in a rapid manner but it was incrementally developed
Are you sure about the placement of word generally there?
To answer your question about parallelism I think "did not emerge" and "developed" are parallel.

and a better way to say it is "developed incrementally" rather than "incrementally developed"

Dear IanStewart,

The officially correct answer of this problem says that “the design (itself) developed painstakingly”. I would much appreciate if you could elucidate how an inanimate thing, such as a design, can “painstakingly” develop? I have a feeling that an adverb “painstakingly” should modify actions of animate beings.

Thank you very much in advance sir.

Yes, I agree completely -- only answers B and E use the word "painstakingly" correctly. If I saw this question on a test, I'd be tempted to pick B for that reason, though it has a parallelism issue unless the word "not" is moved before the first verb (if it said "did not emerge", I think it would be fine). So I don't think there's a good answer to the original question.

daagh posted an official question above that was presumably the basis for this question, and that's the version of this question that I'd recommend studying.

did not emerge in a rapid manner but developed painstakingly.

It is correct from parallelism, however I have doubt in emerge , it should be emerges as its subject is " The design"

Please explain.

Thanks
