Please answer this: W: Yes. I have one here that may interest you. M: Ah, yes. A friend told me about it. What make is it? W: It's a Lincoln. M: Is it MS 560 or MF 558? I don't want either of them. I want a MF 650 one. W: Oh, it's the one you want, and it's three years old. M: Mmm... hmm. And what sort of condition is it in? W: It's in very good condition and it's compact. M: Right. And how much are you asking for it? W: Three thousand and fifteen dollars. M: Three thousand and fifteen dollars? That's a lot of money for a second-hand car. W: But it's in excellent condition.

A: M: Could you tell me how much it is to send a postcard by airmail to Europe?
Problem: Given the question: W: I'll try. M: Thank you. I'm just sitting here in traffic. There must be an accident or something. I've been here for 30 minutes, and I've barely made it onto the bridge. W: Oh, that's not good. M: This traffic is really stressing me out. I don't want to have to take a later flight! W: I'm sure you'll be able to make it. The plane doesn't leave for another 2 hours. M: Yes, but Google Maps is telling me that I won't be at the airport for another hour and 45 minutes, which means I'll only have 15 minutes to check my bags, get through security, and arrive at the gate. That's impossible! W: You can ask to skip to the head of the line in security. They're usually pretty good about that when you think you might miss your flight. M: I hope so.
