     请教下面这题，应该如何分析。谢谢。

According to a study by the Carnegie Foundation for the Advancement of Teaching, companies in the United States are providing job training and general education for nearly eight million people, about equivalent to the enrollment of the nation’s four-year colleges and universities.
(A) equivalent to the enrollment of
(B) the equivalent of those enrolled in
(C) equal to those who are enrolled in
(D) as many as the enrollment of
(E) as many as are enrolled in

答案是E.

首先 equivalent和equal大多修饰不可数名词，所以排除ABC

D结构不对称，把people和enrollment对比。

所以选E，注意E中的as many as those are enrolled in有省略。
