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:     Does Tom drink a lot ?  
 Person2:  Yes , he does . He often has had one to many . But I advised him not to drink too much , he just boasted that he had hollow legs and nobody had ever drunk him under the table .  
 Person1:      That's a problem . He has sort of Dutch courage and that will egg him on in doing anything .
