A、In a ship. B、On a bus. C、On a plane. D、In a car. C推理判断题。对话中提到了air pressure (大气压力)，对话最后男士问restroom (洗手间)在哪儿时，女士告诉他在飞机的后部，由此可以判断

W: Hello there. How are you doing?
M: Fine so far, but my cars feel a little funny.
W: That’s the air pressure. You’ll get used to it in a little while.
M: Can I unfasten my seat belt now?
W: As soon as the light ’above your seat goes off, then you can get up and walk around.
M: Will there be a movie?
W: Yes, but not until after we have served dinner.
M: Will that be soon?
W: Yes, right away. You must be hungry.
M: Not very, but I would like a drink, please.
W: I’ll bring you one. Would you like a coke, beer or wine?
M: Just water, please.
W: Would you like to see a magazine?
M: Yes, I like to look at Newsweek please and could you tell me where to find the restroom?
W: It’s right to the back of the plane.
M: I’m grateful for your help.
W: It’s my pleasure.
