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:     Finally the class is over . Be quick . Ben must have been waiting for long .  
 Person2:  Oh , I am so tired . My back is sore and my neck hurts .  
 Person1:      That's normal . You have been sitting for three hours , with your attention highly concentrated .  
 Person2:  You are wrong , Shirley . I was always absent-minded in the class . I meant to concentrate on the class , but I was just so tired . Maybe I am old .  
 Person1:      No . You are just burning yourself out these days . Have a good rest and you will feel energetic again .  
 Person2:  One of my friends took the Adult College Entrance Exam last year . He filled the school column with his name , and his score was relinquished .  
 Person1:      How could he make such a silly mistake ?  
 Person2:  He said he hadn't taken any exams for ten years , and couldn't get used to it immediately . He was extremely nervous then .  
 Person1:      He lost a very good chance to go to college , didn't he ?  
 Person2:  Yeah . The test was fairly easy and almost every test-taker could pass that exam . Adult College Entrance Exam is much easier than college entrance exam . And there are fewer subjects .  
 Person1:      That's a very good lesson . We must familiarize ourselves with the exam from now on .
