紧急求助 GWD1-32 9９月15日考

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.

>>

1. have to know a great deal more than now about the social and economic
   
2. have to know a great deal more than they do now about the social and economical
   
3. would have to know a great deal more than they do now about the social and economical
   
4. would have to know a great deal more than they do now about the social and economic
   
5. would have to know a great deal more than now about the social and economical

答案是e, 但有两点不解　１）应该用economic 还是economical?我觉得这里似乎应用econimic：经济的，而economical 指的是节约的；２）应用more than now 还是more than they do now? 请斑竹及各位ＮＮ指点迷津　万分感谢！其实这个题以前有个兄弟问过不过没人答复

i think D is right.

(1)从意思上考虑，用economic (2)从比较的结构看，D合适

答案确实是Ｅ　感谢楼主！
