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 narrator likes to listen to music .The narrator does not speak English .The narrator likes to have study tapes on while he is out .The zoo 's guides do n't speak English .
