Question

— Could you tell me ________?

— I'm so sorry. I checked it twice but didn’t notice the fault.

A.what you would do to avoid making a mistake

B.how you made such a foolish mistake

C.who made the foolish mistake

Answer

B

【解析】

句意：——你能告诉我你怎么犯了这么愚蠢的错误吗？——我很抱歉。我检查了两次，但没有注意到错误。

考查宾语从句。what you would do to avoid making a mistake你会做什么来避免犯错误；how you made such a foolish mistake你怎么会犯这么愚蠢的错误；who made the foolish mistake谁犯了这个愚蠢的错误；根据句意理解及后句I checked it twice but didn’t notice the fault.可知，这里表达的应该是询问怎么会犯错误，故选B。
