a) but also to monitor it to gather information
b) but also monitor it to gather information

i am not sure wheter a) or b) to choose? i prefer a)

Choose B

To not only X but also Y

X and Y have to be parallel

In option A but also to [/b breaks parallelism.


Hope this helps![/u]

ah so it can never be:

to not only x but also to y

i thought that the second "to" is needed for parallelism?!

k check this out

Not only X but also Y

For X and Y to be parallel, they should have the same form/structure. We cannot insert 'To' as in the example you have suggested below.

To not only X but also to Y

There is nothing between not only and X... so there should be nothing between but also and Y for maintaining parallelism.

So the sentence should say

not only to x but also to y - correct & maintains parallelism

or

To not only X but also Y - Correct....... here 'To' applies to both X and Y

HTH!!

good explanation, thx
