So difficult ____that no one could ___ a good solution to it.

A．was the problem; come up with

B．the problem was; come up with

C．the problem was; put up with

D．was the problem; put up with

答案

A

解析

试题分析：考查倒装句和区分动词短语。句义：那个问题那么难以至于没有人可以提出解决方案。把握句首关键词so ,句型so…that …如此。。。以至于。。。，如果so 位于句首构成倒装，所以排除B C ,come up with提出 put up with 忍受，根据句意，所以A正确。
