【正确答案】The woman's problem is that she will soon graduate from university, and her parents are coming for the ceremony. Unfortunately, all of the local hotels near the university are full.
The woman's friend suggests that her parents can stay in the student's apartment. If that is not feasible, she can rent a hotel room for her parents within twenty minutes driving distance.
I think her parents should stay with her since she has limited money and cannot afford to pay for a car rental as well as the hotel. It is true that her place is small, but her parents will only be here a short time. A few nights on a sofa is all right.

【答案解析】[听力原文]
M: Karen! It's almost your Graduation Day! You should be happy.
W: I would be happy, but there's a problem.
M: Tell me, I'll try to help.
W: Well, my mom and dad want to come to my graduation ceremony, of course. But they live out of state, so they have to fly. I've been trying to find a hotel for them, but they are already booked up. I'm so stupid! I waited until too late to book the hotel.
M: Why not just have them stay in your apartment with you?
W: You've seen my place. It's so small. I'd have to move all the furniture and rearrange my room if they live with me.
M: Maybe clean it as well?
W: No jokes! I'd even have to sleep on the sofa!
M: Then get them a hotel a little farther from the university.
W: But that's twenty minutes away by car. Plus I'd have to rent them a car. They're my guests, and I really can't afford it.
M: You had better think fast. There's not a lot of time left!
