answer: #Person2# tells #Person1# how to get to the nearest public library.
documents: #Person1#: Excuse me. Can you tell me the way to the Public Library?
  #Person2#: The Public Library? But there are so many public libraries in London. Which one do you want to go to?
  #Person1#: The nearest one.
  #Person2#: 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.
  #Person1#: And where's the No. 7 bus-stop, please?
  #Person2#: 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.
  #Person1#: Thank you very much.
  #Person2#: Not at all.
