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:     Hi , Mr . Zhang . What ’ s wrong ? You don ’ t look so happy . How was your date ?  
 Person2:  I was turned down again . It ’ s frustrating . I guess you ’ Ve got to teach me some skills .  
 Person1:      Me ? I ’ m even less experienced than you are .  
 Person2:  At least you know what American women generally like in a man .  
 Person1:      Believe it or not , I guess American women like a man in good shape , which Chinese women may not care about so much . That ’ s my honest opinion . I know you have been trying very hard .  
 Person2:  American men are naturally taller than Chinese men . So even if I exercise , there aren ’ t many chances .  
 Person1:      No , that ’ s not true . I ’ Ve met two American women who were married to Chinese . But those Chinese look very strong and healthy . So if you exercise more often , I bet it will surely be easier for you to date American girls . How old is Jacky Chan ? He ’ s small and short . But I bet he can have any American woman he wants .  
 Person2:  You know , that ’ s going to be a tremendous change for me . Because I never exercise .  
 Person1:      Why don ’ t you try then ? Even if it doesn ’ t help you find an American girl , you could still have a stronger and healthier body . You won ’ t lose anything by doing that .
