The medical reform in that country proved to be failure, but as we know, success often comes after failure.

A. a; the

B. a; /

C. a; a

D. /; /

答案：

A. a; the

(答案→)B. a; /

C. a; a

D. /; /

解析：考查冠词：第一空填a，a failure这里受抽象名词具体化，表示“一件失败的事情”，第二空不填，这里的failure是抽象名词，不加冠词，句意：那个国家的医疗改革证明是个失败，但是我们都知道，失败是成功之母。选B。
