A: Good morning, miss Harington, please, have a seat.
B: Thank you. You called me. Whad did you want from me?
A: I decided that I can afford you to pass exam today. Are you ready, am I right?
B: Oh, yes, ofcourse!  But I'm really afraid of! Oh..
A: Don't be afraid, it's all very easy. So..I just wanted to ask you about something interesting. As I think it isn't usual exam, because I decided to try new method and give my exams some variety. I just want to give you some questions, and after that to begin our exam, because I want your relaxing. You just can pass your exam when you don't care!
B: Oh, sounds good!
A: And I think so. So..your first question: did you know that at the moment sciencists conduct one interesting experiment? They want to create new engine, which will be allow to develop speed from 200 to 400 k\hour! What do you think about it?
B: I think that this engine, known as "new U2S" isn't useful, because no one normal man won't be drive so fast, as I think. I also can't see some difference between old engine and new, because they're diffirent just at speed.
A: But I think that it's the sign of development of our planet and car-sport! Because I really like  races and watch them on the tv every evening. I think that it will allow to drive rapidly than usually, and get around one of the racers other racers!
B: It may be very dangerous! Do you know about it?
A: Oh, I'm sorry, I didn't think about it.. But I think that they did the simulator of driving and can be very careful!
B: Maybe. But at the moment we have very highly fares on the driving. It's terrible. And I just can't see anything interesting in it. I also think, if you can't allow yourself to buy gasoline, you also can't but new engine "U2S". I don't think, that it's necessary. And..could I pass my exam now? I'm hasting.
