Example Input: M: Hello, Nora. I heard about a flat that might interest you girls. It's near the central bus station on the main road and about 75 pounds a week. Quite reasonable. The problem is, it's only got 2 bedrooms, but I expect two of you could share. ,F: Well, as long as it isn't me, I've got to have my own room because I'd be working at home m ost of the time. Any other information? ,M: Yes, it's got a very big and well equipped kitchen. And I know you like cooking so that's another point in its favor. But there is a small sitting room and not much furniture yet, so let me know quickly if you want it or it will be taken.
(A) F: It has a large sitting room but it doesn't have a kitchen, right? (B) F: I am sorry. You spoke so rapidly that I did not catch the meaning of what you said. Could you repeat that?
