Parliament did not accord full refugee benefits to twelve of the recent immigrants because it believed that to do it rewards them for entering the country illegally.
(A)to do it rewards
(B)doing it rewards
(C)to do this would reward
(D)doing so would reward
(E)to do it would reward
答案D
我想問的是不考慮與前面it believed的it會產生歧義外,
畫線中的it不能代替一件事或是一個動詞
所以要用so囉
