听力原文：M: Hello. Nancy. This is Bob, How are you？

W: Fine. thank you. A bit too busy though. You know, I'm trying to put everything in order in my new list.

M: Oh. I see. Well. I was wondering if you would like to go to a concert to- morrow night. I think it will be good. And if I remember correctly, you did say you liked country music.

W: Yes. That's right; I do. It's nice of you to ask. Bob. But I don't think I can. Mother has already asked me to see a friend and then we'll go to the theater together. In fact she's getting the tickets this evening.

M: Oh. well, never mind. What about next weekend？ This concert is still on then, I think, if you are free next Saturday.

W: Oh. I'd like to very much. But what time exactly？

M: It starts at 7:30. I think.

W: Oh. good. That'll be fine. The tennis match will be over by five o'clock, I'm sure.

M: Good. I'U call you again when I get the tickets.

W: Sure. Bye now.

Why does Bob call Nancy？

A．To ask if she's got the tickets.

B．To invite her out for an evening.

C．To offer his help with his new flat.
