F: Excuse me, sir, can you help me? I need to buy a bed for my new apartment. ,M: Of course, what size bed do you need? ,F: It's a small apartment so I don't want anything too big. ,M: Well, you should get a twin bed. That's the smallest size for an adult. It only fits one person. A bigger size bed is a double bed for 2 people. Then there are queen size and king size beds. Those are very large. There are much too big for you. ,F: OK. Thanks so much I'll get the smallest one.
(A) M: Sorry, we don't have any apartment with twin bed. (B) M: OK. This is the key for the apartment with a twin bed. (C) M: Excuse me, could you repeat the question? (D) M: Sorry, we don't have a queen-sized bed like you asked.
