Parallelism +Idiom

The construction not．．．but shows a contrast．The words following not must be parallel in construction to the words following but．In the original sentence not is followed by a prepositional phrase(in a flash of inspiration)；but is followed by a verb(evolved)．To make the two contrasting elements parallel，not should be followed by a verb rather than a phrase．

A  Construction following not is not parallel to the construction following but．

B  Construction following not is not parallel to the construction following but ,the passive voice were evolved is incorrect．

C  Correct．In this sentence，not is followed by the verb spring just as but is followed by the verb evolved．

D  Had evolved introduces an incorrect verb tense．

E  Construction following no．t is not parallel to the construction following but．

The correct answer is C．
