请教XDJM：

School 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

请问题目中which的先行词应该是housing integration吗？因为这决定reduce的单复数。还有该句怎么翻译比较好？

I think this is a question in XDF's GMAT Supplement study material.

yes, which refers to housing integration.

大致意思：学校集成计划增加了房子聚居，继而减少了对通勤的需求。
