---Have all the mysteries been cleared up?
--- Almost. But ______ only one question ______.

A．there remains; answered	B．it remains; to be answered
C．there remains; to be answered	D．it remains; answered

答案

C

解析

试题分析：考查there be 句型及不定式作定语。句意：---所有的谜团都解开了吗？---几乎都解开了。只剩下一个还未解决。There remains…是there be句型的变形，第二空to be answered是不定式的被动做定语，表示“有待解决”，选C。
