标题: GWD 1－32

Q32:

To develop more accurate population forecasts, demographers have to know a great deal more than now about the social and economic determinants of fertility.

have to know a great deal more than now about the social and economic

have to know a great deal more than they do now about the social and economical

would have to know a great deal more than they do now about the social and economical

would have to know a great deal more than they do now about the social and economic

would have to know a great deal more than now about the social and economical

答案选的是e，好像不太对吧，和social 并列的应该是economic，怎么会是economical呢？所以偶认为答案应该是d吧
