C for me. Not spring...but evolved is idiomatic. In A, Not in a flash of inspiration...but evolved is not parallel.

C. Other options are not maintaining parallelism.

After search I found that choices are different in the question:

original wrote:

A) sprang to life not in a flash of inspiration but evolved slowly
B) sprang to life not in a flash of inspiration but were slowly evolved
C) did not spring to life in a flash of inspiration but evolved slowly
D) did not spring to life in a flash of inspiration but had slowly evolved
E) did not spring to life in a flash of inspiration but they were slowly evolved

still the OA is C.

In D, the use of past perfect 'had evolved' to describe the nature of a phenomenon is erroneous. The springing and evolving are concurrent happenings and so there is no need to sequence them as one before the other. That is why D loses

This question tests parallelism. Indeed most of the wrong answers can be eliminated simply because of lack of parallelism (see below).

The voluminous personal papers of Thomas Alva Edison reveal that his inventions typically sprang to life not in a flash of inspiration but evolved slowly from previous works.

(A) sprang to life not in a flash of inspiration but evolved slowly

'Not in a Noun Phrase but in a Noun Phrase' is violated by the use of the verb 'evolved.'

(B) sprang to life not in a flash of inspiration but were slowly evolved

Same problem as in (A), but this time because of 'were slowly evolved.'

(C) did not spring to life in a flash of inspiration but evolved slowly

'Did not 'Verb Phrase + Prepositional Phrase but 'Verb Phrase + PP' is maintained here. The Answer.

(D) did not spring to life in a flash of inspiration but had slowly evolved

The use of past perfect, 'had...evolved' is unnecessary.

(E) did not spring to life in a flash of inspiration but were slowly evolved

Use of the passive construction, 'were slowly evolved' invalidates this answer choice.

Hope that helps

But if we need to maintain parallelism, spring is just in base form where as evolved is past tense . Can someone please explain this?

(C) did not spring to life in a flash of inspiration but evolved slowly

Notice that "did" appears before "spring". Hence we cannot write "sprang" because we cannot write two past tenses in same sentence. Note that "did not spring" = "sprang" which is parallel to past tense "evolved". The structure of the sentence is such that "spring" and "evolved" cannot be identically parallel. But both the verb tenses are in simple past tense. And that is why they are parallel.

Hence, it is not always necessary that all the entities in a list must be identically parallel. They should be made identically parallel only when it is possible to do so. In an e-gmat course concept namely Parallelism - Helpful Tips, we discuss how far entities can be parallel in the list.

Hope this helps.

Thanks.

Hi Chris,
You mention the above as the reason why E is wrong.
So, Do we need the voices ( passive/active ) to be parallel in a x but y structure?

Regards,
Sach

(A) sprang to life not in a flash of inspiration but evolved slowly structure not X but Y should be grammatically parallel - in a flash is not parallel to evolved
(B) sprang to life not in a flash of inspiration but were slowly evolved structure not X but Y should be grammatically parallel - in a flash is not parallel to were slowly
(C) did not spring to life in a flash of inspiration but evolved slowly CORRECT - structure X but Y should be grammatically parallel - did not spring is not parallel to evolved
(D) did not spring to life in a flash of inspiration but had slowly evolved grammatically nonparallel
(E) did not spring to life in a flash of inspiration but were slowly evolvedgrammatically nonparallel
