[求助]一道GWD语法，if only的用法

Building large new hospitals in the bistate area would constitute a wasteful use of resources, on the basis of avoidance of duplicated facilities alone.

A.              on the basis of avoidance of duplicated facilities alone

B.               on the grounds of avoiding duplicated facilities alone

C.              solely in that duplicated facilities should be avoided

D.              while the duplication of facilities should be avoided

E.               if only because the duplication of facilities should be avoided

答案是E，这句话是什么意思啊，C为什么不对呢？请指点！

c 和e 区别在于表达方式，体会一下 duplicated facilities 和 the duplication of facilities 的区别

意思是   只要有一种标准：重复（建设）设施应该避免，那么建大型的医院就是一种浪费。

这里重点强调的dupication ，而不是facility，这题错过好几遍...
