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:     May , is the university a terrible place ?  
 Person2:  Surely not . Life in the university is fun . Why did you ask ?  
 Person1:      Because you study day in and day out for the entrance exam . So I figure you would study even harder after you ’ Ve got in .  
 Person2:  Studying in the university is not easy , but it's not as arduous as you think .  
 Person1:      How do you know that ? You haven't got in yet .  
 Person2:  Of course I know . I once attended Lisa's class , sitting quietly at the back of the classroom .  
 Person1:      Oh , really ? Were you not caught ?  
 Person2:  Of course not . You are allowed to attend any lecture , only if there are empty seats for you and you don't disturb the class . In universities , you study in a free and creative environment .  
 Person1:      What do you want to study in the university ? Have you thought about it ?  
 Person2:  This question has really been bothering me . I like Chinese literature , you know . But economics is really hot now , and it has a very good career prospect .  
 Person1:      I will choose what I like . You don't know what a torture it is for me to study English , because I don't like English .  
 Person2:  Though I like Chinese literature very much , I'm also interested in economics . It's a tough choice to make .  
 Person1:      You can decide later . You will have choices before you submit your university application form .  
 Person2:  Right . I have lots of time to think carefully before I make my final decision .
