Question

Choose the part of the sentence (one among A, B, C) containing an error in it.
(A)Farmville is the largest rage / (B)on social networking sites these day and / (C)has a big fan following

Answer 1

B) on social networking sites these day

It should be ‘these days’ not ‘these day’

As these is used with plural and day is singular

Answer 2

The whole sentence when written out, there is something that doesn’t feel right.

So writing out “Farmville is the largest rage on social sites these day and has a big fan following”.

Here the “these day” part is not right as I it should be “these days”. So, the option B is the correct answer.
