【正确答案】 C

【答案解析】[听力原文]
   W: Hey taxi!
   M: Where to?
   W: Well, I'm going to the National Museum of Art.
   M: Sure. No problem.
   W: Excuse me. How long does it take to get there?
   M: Well, it depends on the traffic, but it shouldn't take more than twenty minutes for the average driver. And I'm not average. I have driving down to an art, so we should be able to cruise through traffic and get there at least eight minutes earlier.
   W: Oh, and by the way, do you know what time the museum closes?
   M: It's half past four. This is your first time to the city, right?
   W: Yeah. How did you know?
   M: Well, you can tell tourists from a mile away in this city because they walk down the street looking straight up at the skyscrapers.
   W: Good for you! Can you recommend any good restaurants downtown that offer meals at a reasonable price?
   M: Umm... The Mexican restaurant. It's not as expensive as other places I know, and the portions are larger than most places I've been to.
   W: Sounds great! How do I get there from the museum?
   M: Well, there are buses running that way, but you would have to transfer a couple of times. And there are taxis too, but they don't run by the museum that often. So you'd better catch the subway right outside the museum.
   W: Okay. Thanks.
   How long does it take the man to get to the museum?
