ron,please!Prep question：The airline's proposed purchases...

[wenjiani41]

The airline's proposed purchases of as many as 250 medium-range planes will probably be the basis of an overhaul of its routes; it is expected that they will increase the number of direct point-to-point flights, instead of continue to use feeder aircraft to bring passengers to major hubs.
A. it is expected that they will increase the number of direct point-to-point flights, instead of continue
B. it is expected that it will increase the number of direct point-to-point flights, rather than to continue
C. it is expected that the number of direct point-to-point flights will increase, instead of their continuing
D. the airline is expected to increase the number of direct point-to-point flights, rather than continue
E. the airline is expected to increase the number of direct point-to-point flights, instead of its continuing

the official explanation of A is
A. The plural pronoun they does not agree with the singular airline but has no other plausible antecedent. The phrase it is expected that introduces unnecessary words.

i remember ron said that, in thursday with ron, the gmat dose not allow the pronoun to indicate something that has 's( sorry, i dont know the name of such things).

however, in this question, the its in not underline part(the red one) indicates the airline. the official explanation of A is that they has to indicate plural stuff, not that they can not indicate the noun with 's.

is their opinion change overtime?

pronoun can refer to noun
possessive pronoun can refer to possessive noun

its refer to airline's. PERFECT

Since a quick Google search says this looks like a question found in the paid prep pack, I'm going to have to remove this question unless someone has a screenshot from the GMAT Prep test.
