问题补充：

—Could I use your bike for today, Sam?

—. I’m not using it.

A. Sure, go ahead

B. I have no idea

C. No, you can’t

D. Never mind

答案：

(答案→)A. Sure, go ahead

B. I have no idea

C. No, you can’t

D. Never mind

解析：句意：－赛姆，今天我可以用你的自行车吗？－好的，你用吧，我现在不用。go ahead表示同意或允许，意为：用吧，做吧。I have no idea我没主意；never mind不要紧，不介意。C项和下文句意矛盾。故选A
