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:     We ’ Ve been over this a thousand times . The data is irrefutable ! Look , we ’ Ve done extensive research , built studies , and read the literature , and there is conclusive evidence to support my theory !  
 Person2:  Horowitz , I beg to differ . Even in your most recent study , the investigative approach was flawed ! You know as well as I do that the collection of data was not systematic , and there is a large margin of error . To draw a definitive conclusion based on that data would be misleading  
 Person1:      That is preposterous !  
 Person2:  You are trying to single-handedly solve one of the world ’ s greatest mysteries , and yet you are oblivious to the fact that you are wrong !  
 Person1:      I am not wrong ! The chicken came first !  
 Person2:  No ! The egg came first !
