正确答案： D:as charge

A、B、C，大的结构是as many .... as，用than错

E is the best

E的those可以向前指代institutions，也可以指代tuition and fees；并且as..as不对称

D可以认为（many independent institutions of higher education） charge（ tuition and fees of），只是无法确定是否可以这么省略。

in choice D,若是ellipsis 的话，structure 为：as many as institutions ~~charge fees as (institutions) charge .此结构比较的是两个句子，强调的为charge 这个动作，而文中的intended meaning 是比较 institutions .

the parallelism is not with respect to structure but with respect to the meaning..SO 不存在不平行的问题。逻辑平行优先于形式平行。

institutions that charge =institutions charging (charging起adj的作用)
