Definition: You are given a conversation between two people. 'Person1:' and 'Person2:' are used to separate their respective dialogues. If the conversation begins with a question, label it '1' otherwise '0'.
Input:  Person1:     You must be pretty excited about your trip to Europe . When is it that you are leaving ?  
 Person2:  In just three weeks , and I am excited . But there are still a few things I need to do before I go .  
 Person1:      Like what ?  
 Person2:  Like renewing my passport , going to the travel agency to buy my plane ticket and figuring out what to do with my apartment while I'm gone .  
 Person1:      You are not going to give it up , are you ?  
 Person2:  No way . I'll never find another apartment around here . But I don't like the idea of paying three months ' rent on an empty apartment , either .  
 Person1:      I don't blame you . Perhaps you could sublet it .  
 Person2:  Yes , but whom to ?  
 Person1:      Mmm ... let me think . Oh , I know just a person . An old colleague of mine , Jim Thomas , is coming here to do some research this summer , from June to August .  
 Person2:  That's exactly when I'll be away . It sounds ideal , as long as the landlord agrees .  
 Person1:      Tell you what , I'll be calling Jim late this week anyway , so I'll mention it to him then .  
 Person2:  Well , thanks , Bill . Let me know what happens . That extra money will really come in handy .
