Input: M: How may I help you? ,F: Hi, I would like to rent a car. ,M: Sure, did you make a reservation? ,F: No, I decided to rent one when I got off the plane just now. Is that OK? ,M: Of course. I was just checking. So how many days do you need the car for? ,F: Can I just do 4 days for now and make the rent longer through a phone call later? ,M: In that case, I suggest you go for 7 days, which will give you a 20% discount. And if you choose to return the car after 5 days, you can get the rest of your money back. ,F: OK, I will do that. Can I return the car at the train station?
(A) M: I am really sorry, I did not catch that. Would you slow down, please? (B) M: Yeah, since you don't like the plan for renting seven days, be sure to return the car in five days, please remember that (C) M: Sure. Remember you only have seven days, and you can only get the rest of your money when you choose to return the car after 6 days. (D) M: Yes, and don't forget to return the car on time if you don't want to be in trouble, you only have seven days for having the car.
