input question: M: May I see your bill, please? W: Certainly. There it is. On July 1st, I really don't know anybody in Finland. M: OK, don't worry. I'll take the call off. Let's see...it was $42. Your bill was $ 66.10, minus $42, so your new total is $24.10. I'm very sorry about the mistake. W: That's OK. It wasn't your fault. What was said before this conversation????

input question: M: Yes, I bought these shoes here two days ago. But they seem too small and press against my feet. W: Let me see, um, what do you think I should do? What was said before this conversation????
output answer: W: Can I help you?

input question: M: I sure did. Why did you ask me about that? W: Well, I'm thinking about taking it next year. I want to know something about it beforehand. M: As far as I'm concerned, I suggest that you not take it. W: Why not? Is the professor awful or is the lecturing boring? M: The professor is nice enough. But the course is nothing but physics and chemistry with lots of equations. You can't just mix the right chemicals and watch what happens. As you go along you have to keep care notes and turn it all into a bunch of numbers and formulas after the experiment is over. It was the worst course I've ever taken. W: What you say is no problem for me. To tell you the truth, [ like formulas and numbers. That's what I'm different from you. M: Is it? Then you'll love it if it is the case. But all that I was interested in was biology and we didn't get to that till the last three weeks of the class. What a year! What was said before this conversation????
