input: Please answer the following: W: Late last night? That's strange. What did he look like? M: He seemed to be about thirty or so. W: Was he tall or short? M: He wasn't very tall, nor very short. About aver age height, I think. W: Was he fat or thin? M: A bit thin, if I remember correctly. Anyway, certainly not fat, but then he wasn't very thin either. W: Was there anything unusual about his looks? What kind of face did he have-round, square or long? M: Let me think...It was rather square, but not very. Or was it? Really, I didn't notice. It was so late and the lighting wasn't good. W: Was he wearing glasses? M: Was he or wasn't he? I'm not sure now. You see, I was so tired and sleepy. I didn't notice. I didn't pay much attention.

input: Please answer the following: Dentist: But I haven't touched you yet. What are you shouting for? Patient: You are going to touch me. Dentist: Well, of course I am. How can I give you an injection without touching you. As soon as you've had the injection your gum will freeze and you won't feel a thing. Patient: How do I know what you will do while I am asleep? You might rob me. Dentist: Now let's not be silly. You won't go to sleep. We don't do that nowadays. This will just freeze the area around the tooth so that you cannot feel any pain while I am pulling out the tooth. That is all. You won't go to sleep. You can watch everything in that mirror above you. Come along now. What was said before this conversation?

input: Please answer the following: W: Hello, Susan's speaking, may I speak to Judy please? M: I'm afraid she is not here at the moment. I am her brother, shall I take a massage? W: Yes, you see, Judy and I plan to play table tennis tomorrow, but my cosine has broken my bat, I think Judy has an extra one, so please ask her to bring it for me. M: So, Susan called, her table tennis bat broke, hope Judy bring an extra one. W: Yes, thank you, er.... One more thing, I lent her a book a couple of weeks ago, I think she has probably forgotten it all together, could you possibly ask her to bring along that book as well. M: Ok, bring along Susan's book. W: Thank you very much! M: Bye! What was said before this conversation?
