(E) in my opinion. Took me 54 secs.
Quote:
John asked Jane to help him move the dining
table, but she refused to do it, claiming her back hurt.
Here,
it is a pronoun, it can only refer to a noun. But here it is incorrectly trying to modify/refer to an action. It's better to use
"to do so/doing so". Thus, reject option A.
Quote:
B. table, but she refused to do that,
That again is a pronoun and it refers to a previously mentioned noun. And thus can not refer back to a previous action in the sentence (here the action of helping John in moving the dining table). Hence, reject option B too.
Quote:
C. table, but she refused to do so,
This corrects the pronoun ambiguity clearly but introduces a slick error. If you didn't pay attention and were in a hurry, you would mark this answer as correct, ignoring the subtle change of
table to
tables. It changes the original meaning where John needs help with moving the dining table, not table
s. Hence, reject this cheeky option C.
Quote:
D. tables, but she refused to do it,
This option has errors from all the options above. Easiest to reject.
Quote:
E. table, but she refused to do so,
This is the remaining option and has the least number of errors in it too. This option correctly uses
to do so to refer back to a verb and does not make any blatant pronoun errors like in Option A and B.
Hence, this is the right option.
