【单选题】

听力原文：W: May I help you?

M: Do you sell alarm clocks in this department store?
W: Yes, we have a wide selection. What exactly did you have in mind?
M: I would like an alarm clock that will awaken me with soft music.
W: In that ease, you'll probably be interested in this handsome electric clock radio in a walnut cabinet.
M: Actually, I'd like a small battery-operated clock radio in a plastic case.
W: Here's a model that should suit you perfectly.
M: Yes, that's just what I had in mind. Can I use my credit card to pay for it?
W: I'm sorry, sir, but we don't accept credit cards in this store. The manager doesn't believe in them.
M: Then can you direct me to a store that carries this same model radio but also accepts credit cards?
W: You could try the appliance store on Dawson Street.
M: Thank you for your help. I'll see if the store you recommended has what I want.
