integration plans that involve busing between suburban and central-city areas
have contributed, according to a recent study, to significant increases in
housing integration, which, in turn, reduces any future need for busing.
(A) significant increases in housing integration, which, in turn,
reduces
(B) significant integration increases in housing, which, in turn,
reduces
(C) increase housing integration significantly, which, in turn,
reduces
(D) increase housing integration significantly, in turn reducing
(E) significantly increase housing integration, which, in turn,
reduce
我选的是e,答案是a。有两个问题我不太明白：
1。which 应该指代 significant increases in
housing integration,那么后面就应该用reduce而不是第三 人称单数reduces，这样可排除a,b,c
2。contribute to 后面可接 do 或者 sth.， 所以e中应该不存在不简练的问题。
所以，为什么答案不是e呢？？？！！！
