A: Excuse me, how long does it take to get to the zoo?
B: Well, the zoo?
A: Yes. Is there anything wrong?
B: You're going in the opposite direction.
A: What should I do now?
B: Take it easy. Get off and take the subway on the opposite side.
A: And at which station should I get off to go to the zoo?
B: At the Zoo Station.
A: But there is not such a station on the route map.
B: What? Oh, you have to change lines.
A: Which line do I need to take?
B: I'm not quite sure. Let me look at the map.
A: Thank you.
B: Look, you can transfer to Line 3 to get there.
