再问OG165

165. At Shiprock, New Mexico, a perennially powerful girls' high school basketball team has become a path to college for some and a source of pride for a community where the household incomes of 49 percent of them are below the poverty level.
(A) where the household incomes of 49 percent of them are
(B) where they have 49 percent of the household incomes
(C) where 49 percent of the household incomes are
(D) which has 49 percent of the household incomes
(E) in which 49 percent of them have household incomes

Key is C.D为何不对呢?ETS这样解释:Furthermore, the use of have in B and E and of has in D illogically suggests that the community possesses 49% of all the household incomes below the poverty line.

但是感觉D和C的意思明明是一样的啊?!

D中的 a community has ... incomes 在本句中产生严重的逻辑错误；

smilingsea, 想想是community拥有49%的income呢，还是在community中的居发拥有49%的income?而且即使这里没错后面 household incomes below the poverty level中也少了个which(在below前）。
