The mathematical concept of "zero" was born not in a single moment of revelation but evolved independently in several ancient cultures, including India, Babylonia, and the Maya Empire.

born not in a single moment of revelation but
born not in a single moment of revelation but was
not born in a single moment of revelation but
not born in a single moment of revelation but it
not born in a single moment of revelation but had

[Reveal] Spoiler:
A quick scan of the answer choices reveals two basic alternatives—"was born not" and "was not born." We eliminate (A) and (B) because "was born not" is not parallel to but evolved. The two verbs are being balanced by not and but. (B) also uses the passive "was evolved" which is an incorrect use of the word "evolve".

(D) unnecessarily adds the word "it." This could only be correct if the form of the sentence were ". . . was not born in a sudden moment of revelation; rather, it evolved slowly . . ." Since that is not the form used here, the word "it" is not needed.

(E) incorrectly uses the past perfect tense "had evolved" because the past perfect is only necessary to compare a sequence of events in which one event precedes another event in the past. Here, there is no sequence of time—the whole sentence is in the same past time.

(C) uses the proper "was not born" parallel to "but evolved" and the proper simple past, active form "evolved".

Hi, I thought parallel structure means if one of the verb is passive, another one must be passive.
Can anyone explain this for me, please.

When it comes to the question of weighing parallelism, correlative conjunction parallelism rides over voice parallelism;

Hi

An active voice entity CAN very well be parallel to a passive voice as long as the subject of the verbs is same....

Also some structures of possible imperfect lists:

1. Noun forms and “ing” noun forms (gerund).
2. Active and passive voice entities
3. Verb-ed and Verb-ing modifiers

Correct idiomatic expression is - Not X but Y ( Parallel Markers)

From the given options (A) and (B) can straigtaway be rejected

born not in a single moment of revelation but
born not in a single moment of revelation but was

Options which looks close

not born in a single moment of revelation but verb+ed = Looks correct

not born in a single moment of revelation but it - It has no clear (Unambiguous antecedent)
not born in a single moment of revelation but had - Had used incorrectly, hence rejected.

Hence IMHO (C) looks the best.

I was debating between option C and E.. and went with E, thinking that 'had' was properly placed.

Looks like I was wrong in thinking that it was a proper use of past perfect 'had.' Why is it incorrect? Is it because of parallelism?

'was not born..' is a simple past, so it should be 'but evolved', which is also a simple past?
