A. have grown; are

B. have grown; is

C. has grown; is

D. has grown; are

答案：

A. have grown; are

B. have grown; is

C. has grown; is

(答案→)D. has grown; are

解析：考查主谓一致： population作主语时谓语动词一般用单数，象第一个空就是单数，但若前面有分数或百分数修饰时，若其后跟的是系表结构，且表语为复数，谓语动词要用复数。第二个空有most of修饰，而且表语是复数，所以be动词是复数，句意：中国的人口已经增加到949年的很多倍，并且大部分人口是农民。选D。
