17. The major purpose of the United States Department of Education are to ensure

          A

   equal educational opportunity for all and to improve the quality of education。

A肯定错了，但是，opportunity 不是可数名词吗equal 前应该加定冠词吧，不解ing

purpose->purposes

opportunity->opportunities

应该是印刷错误

找到句子的谓语问题不就解决了吗?OPPORTUNITY之后没有OF,因此可以不用再限定THE了.OK.
