Q: What might have happened?

A: They were having in a party.

B: They were having a talk in the phone.

C: The place they were staying had the power off.

D: The man used the woman’s phone to save his life.

解析:C。A不正确,虽然有fun,但是不是在party。B不正确,这是发生在现实中的谈话。D不正确,不可以说是use the phone to save his life. 单从原文理解,至少也应该说是女方救了男方。C正确,从blackout中听出来。

======原文=====

Jill: Well, this has been fun.

Chandler: Yes. Yes, thanks for letting me use your phone... and for saving my life.

Jill: Well, goodbye Chandler. I had a great blackout. (she kisses him on the cheek) See ya.
