问题补充：

--- How far can you run without stopping ?

--- . I’ve never tried.

A. Don’t mention it.

B. That’s all right.

C. I have no idea.

D. Go ahead.

答案：

A. Don’t mention it.

B. That’s all right.

(答案→)C. I have no idea.

D. Go ahead.

解析：句意为：---一直不停地你能跑多远？---我也不知道，我没有尝试过。 由后面I’ve never tried我没尝试过可知，我也不知道自己能跑多远，Don’t mention it 不值得一提；That’s all right 不必客气，没关系；go ahead 用吧，开始。故答案应为C。
