W: Excuse me. Can you tell me the way to the Public Library? M: The Public Library? But there are so many public libraries in London. Which one do you want to go to? W: The nearest one. M: That's rather far away, too. You'd better take a bus. Take the No. 7 bus to the zoo, then change to the No. 9 bus and get off at the end. W: And where's the No. 7 bus-stop, please? M: Go straight down the street, and turn left at the traffic lights. Then take the second turning on the right, and you'll find the bus-stop near the corner. You can't miss it. W: Thank you very much. M: Not at all., Question: Where will the woman change buses? (A) At the zoo. (B) At the traffic lights. (C) At the end of the No. 9 bus.
(A) At the zoo.
