I think tomorrow I ' m going to stay in and relax and do some studying and stuff ... if I get bored I might go to Ueno . Apparently Ueno has a zoo , a museum and a park . I think I might go to the park tomorrow and then go to the zoo and the museum later this week . Yuko says the museum has little ear phones you can use to hear English translations of the tour .

Question: Why does the narrator need ear phones at the zoo ?
Answer: The zoo is in a foreign country .The narrator likes to have study tapes on while he is out .The narrator likes to listen to music .The narrator does not speak English .
