Problem: M: I know, this is another routine mission. It is first flight with four years ago. What was said before this conversation?

A: W: The space shuttle is taking off tomorrow.

Problem: W: Yes, But Sam is much taller than John. What was said before this conversation?

A: M: John is a head taller than Mary and Shelly.

Problem: 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?

A: W: Oh! I am glad to see you. How are you going recently? They say you took Introduction to Seience, didn't you?

Problem: M: Well the biggest change has been the decrease in sales since the great boom years of the 1980s when champagne production and sales reached record levels. W: Which was the best year? M: Well the record was in 1989 when 249 million bottles of champagne was sold. The highest production level was reached in 1990 with a total of 293 million bottles. Of course since those boom years sales have fallen. W: Has the market been badly hit by the recession? M: Oh certainly, the economic problems in champagnes' export markets that's Europe, the United States, Japan, and of course the domestic market in France, the economic problems have certainly been one reason for the decrease in champagne sales. W: And the other reasons? M: Another important factor has been price. In the early 90s, champagne was very overpriced, so many people stop buying it. Instead they bought sparkling wines from other countries, in particular from Australia and Spain. And then there was another problem for champagne in the early 90s. W: What was that? M: There was a lot of rather bad champagne on the market. This meant the popularity of good sparkling wines increased even more. People was surprised by their quality and of course they were a lot cheaper than champagne. W: Do you think the champagne market will recover in the future? M: Oh, I'm sure it will. When the economic situation improves, I believe the market will recover. What was said before this conversation?
