Task: Question Answering
Input (English): Passage: I play the guitar . I decided to play a new song . First , I decided which song I wanted to learn to play . Then , I walked to the bus stop . I waited for the bus . I rode the bus to the mall . I went inside the mall . I walked into the music store . I looked through books of sheet music , until I found a book with the song I wanted to learn how to play in it . I paid for the book with my allowance money . Then , I went outside and waited for the bus . I rode the bus home . I opened the book and turned to the song . I studied the song for a couple of hours . Then , I picked up my guitar , tuned it , and started to play the new song . The chords were arranged a lot different than I am used to playing , so it took me quite a long time to practice it before the song sounded right . Question: When did they take the book to their room? Option1: Before going to the mall Option2: When coming home
Output (English): When coming home
