[讨论]大全上的150题，答案选 C，但D似乎也可以。

1.     
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（C）

(E) in which 49
percent of them have household incomes

D is incorrect.

It is incorrect to have such sentence as:

The community has 49 percent of the household incomes below the poverty level.

I agree, the logic meaning of C is very unclear!
