Hi Sachin,

In the construction “not X but Y”, X and Y should be parallel, but it is not necessary for the voices to be the same if the context demands so. For example:

The beggars did not get any money but were helped in other ways.

In this sentence, “did not get” is in active voice but “were helped” is in passive. It is so because here both the entities cannot be identically parallel. If we make both the voice active, the meaning will be violated.

However, this is not the case with the OG question. Choice E reads:

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

In this choice we can make both the entities identically parallel without violating the meaning of the sentence. We can easily say:

Did not spring to life in a flash of inspiration but slowly evolved…

The takeaway is that we must keep the entities as parallel as possible. When we can have identically parallel entities to convey the intended logical meaning, we must keep them that way. The list can be made non-identical only if the logical meaning cannot be conveyed by making the entities absolutely parallel.

Hope this helps. :)
Thanks.
Shraddha

Amazing.. Thanks a ton..

Is it also because usage of evolve mandates that? since evolution happens and not done by somebody?

Hi Shraddha,

Thanks for this information... It will be useful...

Just have a basic doubt !!

What about tenses in “not X but Y” parallelism.
Both should be of same tenses??

e.g ) I did not study well but i will score in exam...

Will this be a correct sentence construction ???

Shanmugham,
I believe it depends on the meaning. If meaning mandates a change in tense, then I guess that wont violate parallelism.

Waiting for a confirmation from Shraddha though :)

Regards,
Sachin


Kudus if it helped :)

Edison reveal that his inventions typically sprang to life
not in a fl ash of inspiration but evolved slowly from
previous works.
(A) sprang to life not in a fl ash of inspiration but
evolved slowly
(B) sprang to life not in a fl ash of inspiration but
were slowly evolved
(C) did not spring to life in a fl ash of inspiration but
evolved slowly
(D) did not spring to life in a fl ash of inspiration but
had slowly evolved
(E) did not spring to life in a fl ash of inspiration but
they were slowly evolved


I'm no help on your question 2, but I will respond to your first question about 'did'.

This is a great meaning question around the difference between "sprang to life not in a flash" and "did not spring to life in a flash". The intent of the sentence is to show that Edison's inventions were not the result of a flash of inspiration but rather were the result of an evolutionary process. By saying his inventions "sprang to life not in a flash of inspiration but evolved slowly" you are actually setting up a contradictory statement because you are saying his inventions sprang to life through evolution, but evolution is slow and certainly does not "spring to life". By changing the statement to read "his inventions did not spring to life but evolved slowly" you get the proper meaning that this was not a quick, 'spinging' action but rather a slow evolutionary process.

Does that help?

You mention that you picked A because verbs were in past tense and parallel. For one thing, tense does not need to be same between various parts of the sentence. For example:

Buddha has studied hard for GMAT and will surely score well on GMAT.

This is a valid sentence, though the tenses are not same (first part uses present perfect and second part uses simple future).

Nevertheless, even going by your thought process, you mention that both verbs are parallel. I am assuming you mean that sprang and evolved are parallel in A. So, let us dissect the sentence at these verbs:

The voluminous personal papers of Thomas Alva Edison reveal that his inventions typically:

(a) sprang to life not in a flash of inspiration
BUT
(b) evolved slowly from previous works.

So, the mini-sentences we have here are:

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


Hopefully you see the issue with (a). We would not say:

He prepared for GMAT not with a hope of scoring 650.

We would rather say:

He did not prepare for GMAT with a hope of scoring 650.
