Answer: W: Welcome sir, go this way please.
Problem: M: Help. I need some help! W: Yes sir. Can you tell me what is happening? M: I'm at the university and a student of mine suddenly fell down, knocked her head on the step, and fainted right at this very moment. W: Yes sir. Can you tell me exactly where you are? M: On the...on the ...I'm sorry, I'm too nervous right now. We're on the second floor of Cutler Hall, Room 211. W: I understand, sir. May I have your name and the student's name? M: Her name is...uh...Anita Rivera. And my name's Lawrence Clark. I'm a professor here at the university. W: Okay, who is there with you? M: Um, Anita and two other students. They're watching her while I call. Do you think we should drive her to the hospital? W: No, an ambulance is already on its way. It should be there very soon. M: Uh, what should we do while we wait for it to come? W: Just keep her calm and warm. M: Okay, well do that. Thank you. What was said before this conversation?

A: W: 911.
Problem: Given the question: M: No. Why do you ask? W: You have so many empty cans here. M: Well, my mum wants me to keep all the cans, so that we can sell them after a while. W: Aha, you are going to make a millionaire of yourself sooner or later with all those cans. M: You bet I will. Well, that's not the point. The point is we separate reusable things from other rubbish. We have to pay the dustman for dealing with rubbish, but if we sell him these cans and other reusable material we pay less. W: That sounds a clever idea. Now what are reused in China? M: Metal, plastic, paper, books and the like. W: Just as we do back home in the States. M: And to avoid waste, the government is limiting the production of goods that can be used only once, such as bamboo chopsticks. For example, all the fast food boxes should be made of paper instead of non-reusable material. W: That will surely be helpful for a clean environment. What was said before this conversation?
