To develop more accurate population forecasts, demographers have to know a great deal more than now about the social and economic determinants of fertility.
A. have to know a great deal more than now about the social and economic
B. have to know a great deal more than they do now about the social and economical
C. would have to know a great deal more than they do now about the social and economical
D. would have to know a great deal more than they do now about the social and economic
E. would have to know a great deal more than now about the social and economical

OA is E

I chose B because it correctly compares what demographer know now compared to what they will know in future by using "more than they do now". But answer is different. Share your thoughts.

I just realized choice B has economical, which is wrong, so I am changing my answer to D. But that is still not the OA
