Why "they were" is correct in A? Why not "they did"? In-fact, shouldn't we be repeating the entire verb when we change the tense - Re: MGMAT SC?
Please somebody with true knowledge give us the real reasoning on how to use these helping verbs to truncate the real verb?
"were [paying]" corresponds to "are paying" earlier in the sentence. if "paying" is already there, you don't have to repeat it.
if it's *not* there, then you have to put it there -- for instance, "they now pay more than they were before" is not ok. in that case you would have to write "they now pay more than they were paying before".
