To develop more accurate population forecasts, demographers have to know a great deal more than now about the social and economic determinants of fertility.
this is the underlined portion:
have to know a great deal more than now about the social and economic determinants of fertility.
down to two options:
1) would have to know a great deal more than they do now about the social and economical determinants of fertility.
2) would have to know a great deal more than they do now about the social and economic determinants of fertility.
2 is correct but why 1 is wrong. What the hell is wrong with writing "social and economical determinants" ? What is the rule for something like this ? PLEASE HELP. [/u]
