economic vs economical - go with the earlier. economical makes it sound like efficient/prduent.

(B), (C), (E) are out.

Between A and D, I'll go with D. D has a idiomatic structure, need to know more... than they do now...

D it is.

A Demographers have been compared to now. Not correct
B Social and economical. This is not a parallel construction
C Social and economical. This is not a parallel construction
D This is the best choice. Hence this is the answer
E Social and economical. This is not a parallel construction

According to Manhattan SC, economical means efficient, and that is what we want to say here, so Im with C.

Hey Noburu,

As I said elsewhere, we definitely don't want "efficient" here, which wouldn't make any sense.

Indeed it makes sense that demographers are more interested in economic matters.
Thanks.
