[求助]大全666

South Korea has witnessed the world’s most dramatic growth of Christian congregations; church membership is expanding by 6.6 percent a year, fully two-thirds of the growth coming from conversions rather than the population increasing.

(A) coming from conversions rather than the population increasing

(B) coming from conversions rather than
   increases in the population

(C) coming from conversions instead of the population’s increasing

(D)
     is from conversions instead of
    population increases（B）

(E) is from conversions rather than increasing the population

多么好的一个题号，可惜这道题我错了....我想选D

1、B用coming from有什么根据，我觉得D的is也可以呀....

2、rather than和instead of在这里是不是都能用，错误点应该不在这吧？

3、population increases不是更简洁么？我觉得它是名词性质的短语，看前辈的讨论帖说increase的用法是increases in，是这样么？求证，可否给个例子~
