“They” must refer to minivans in this sentence
Minivans carry as many as seven passengers and, compared with most sport utility vehicles, cost less, get better gas mileage, allow passengers to get in and out more easily, and have a smoother ride.
A. Minivans carry as many as seven passengers and, compared with most sport utility vehicles, cost less,
B. Minivans, which carry as many as seven passengers, compared with most sport utility vehicles, they cost less,
C. Minivans carry as many as seven passengers, in comparison with most sport utility vehicles, and have a lower cost, they
D. Minivans, carrying as many as seven passengers, compared with most sport utility vehicles, cost less,
E. Minivans, which carry as many as seven passengers, compared with most sport utility vehicles the cost is lower, and they
B, D and E seem to suggest that the part “cost less, get better gas mileage, allow ……………………..” will hold true only in the case of minivans carrying seven passengers. This changes the intended meaning.
In B, C and E “minivans…..xyz, they” is incorrect sentence structure.
Choice A correctly uses the conjunction “and”, which implies that both things i.e. the number of passengers and the other things about the minivans are true but aren’t necessarily dependent
