Is this parallel? Both “either” and “or” have prep phrases that start with “on”. Or is this not parallel because “vaccination” doesn’t match “exterminating”?

“either on vaccinating of humans or on the extermination of”

Same question as I put above. Both the X and Y elements here start with the preposition “on”. Is “on” alone enough to make these elements parallel? Do the “vaccinating” and “extermination” portions of the X and Y element matter?



Hello PurpleDrank3000,


You certainly ask a good question here. :thumbup:



However, there are certain considerations here.

Firstly, vaccinating of humans is an incorrect expression. We can say vaccinating humans or vaccination of humans.

Similarly, we can use extermination of mosquitoes or exterminating mosquitoes in the context of this sentence.

So let's work with these expressions.

As long as the sentence uses either X or Y, either on vaccinating humans or on the extermination of mosquitoes AND/OR either on vaccination of humans or on exterminating mosquitoes will be parallel because ultimately both either and or are followed by prepositional phrases.


But suppose if this sentence only uses the parallel marker or and not either X or Y, then in that case neither vaccinating humans can be parallel to the extermination of mosquitoes nor vaccination of humans will be parallel to exterminating mosquitoes.

The verb-ing noun forms cannot be parallel to a conventional noun. The reason for the same is that verb-ing nouns denote action while the conventional nouns denote a person, a place, or a thing.


Coming back to the official sentence, we see that the correct answer choice uses perfect parallelism even after the preposition on because a parallel list must be as much parallel as possible. If the two expressions can be written in identical form, then they must be written so.



Hope this helps. :-)
Thanks.
Shraddha
