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:     What's your favorite sport ?  
 Person2:  It's hard to say . Perhaps swimming is my favorite . I like swimming because it helps improve my lung capacity . In the scorching summer days , there's nothing like a cool swim . Currently , I go to the pool twice every week .  
 Person1:      Is the entrance charge expensive ?  
 Person2:  Well , it costs an arm and a leg — 30 yuan per person . What a costly sport ! That is why I have to refrain from even thinking about it . And I find jogging a very agreeable substitute .  
 Person1:      Haha , jogging ? Perhaps it might be a bit too boring ?  
 Person2:  You know what ? You won't get a rush from it until you fully understand it . It is a simple sport and doesn't require skills of any sort . This leaves room for me to enjoy the beautiful suburban scenery while jogging . Fresh air caresses my face and blows into my chest , which translates into inspirations . Inspirations are really good stuff for a writer like me . Sometimes , I even come up with a verse or two .  
 Person1:      You are really a man who knows how to enjoy being alone .
