Not only verb, but also verb

Only C maintains parallelism.

Answer C - Used Not only and but also parallelism and only this one suits.

(C) something which could not only achieve a state of inner balance and relaxation, but also improve.

ADE fail this test. Also between B&C, B fails the parallelism ..

CRACK VERBAL OFFICIAL EXPLANATION



The correct parallel structure is “something which can/could not only X… but also Y”, where and Y are actions that can be accomplished. Here, X should be ‘achieve a state of…’ and Y should be ‘improve focus, eye coordination etc.’. i.e. X and Y are both verbs.

Option A: is of the form ‘something not only which X but Y’ –> not parallel.

Option B: the presence of ‘to’ before ‘improve’ is unnecessary.

Option D: ‘that being’ is not required here. ‘achieve’ and ‘improving’ are not parallel.

Option E: is of the form ‘not only which could X but also Y’ –> not parallel.

Thus, C is the right answer.

Hi,

I don't understand why option B is wrong. Isn't 'could achieve' parallel to ' to improve'?


Kindly Explain.
