快要考了，问一道XDF上面的题目

SEC 17

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.

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，为什么b不对呢？

because也是ets首选之一

个人感觉主要是B 的逻辑不通--- 我们不能说设施facilities 被avoid,只能说the duplication 被avoid
