问题补充：

—Are you going to the countryside for holiday?

—. I wonder if I’ll be free then.

A. Let’s go

B. It’s up to you

C. Take it easy

D. It all depends

答案：

A. Let’s go

B. It’s up to you

C. Take it easy

(答案→)D. It all depends

解析：句意：你打算去乡下度假吗？我想知道那时是否用空。可知作者不肯定。所以选D．It all depends看情况而定。A,B,C表示接受对方的观点，不合题意。
