[speaker001:] Dear, can you drive me to the clinic?
[speaker002:] I'm afraid I can't.
[speaker001:] Why?
[speaker002:] Well, my car won't start. I don't know what's the matter with it.
[speaker001:] Could it be the battery?
[speaker002:] No, I don't think it could be. I checked the battery two days ago. It must be other problems.
[speaker001:] Well, I suppose it could be the gas.
[speaker002:] No, there is plenty of gas. I filled it up yesterday.
[speaker001:] Perhaps it's the starter then?
[speaker002:] Yes, that's possible.
