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:     Hello everyone , and welcome to our CPR for beginners course.First of all , does anyone know what CPR stands for ?  
 Person2:  Cardiopulmonary resuscitation !  
 Person1:      That ’ s right ! We apply CPR in the case of cardiac arrest or pulmonary arrest .  
 Person2:  What does that mean ?  
 Person1:      Well , basically if your heart stops pumping blood , or your lungs stop pumping air , then we need to get them going again ! That ’ s when we have to apply this procedure . Let ’ s begin ! I need a volunteer .  
 Person2:  Me ! Me !  
 Person1:      Alright , come here and lay flat on your back . Let ’ s suppose this young woman has stopped breathing . We must lift the person ’ s chin so that we clear a pathway for air to get into the lungs . Then we place our mouth over the other person ’ s mouth and blow air two or three times , like this .  
 Person2:  Wait , what are you doing ? I ’ m a married woman ! You can ’ t just try to kiss me like this !  
 Person1:      Madam I ’ m not trying to kiss you ! I am trying to demonstrate how to apply CPR in the case of an emergency .  
 Person2:  Well , OK . But no French kissing !  
 Person1:      As I was saying , we blow air through the mouth in this manner . Once this is done , we must try to get the heart going again . To do this , we place our hands over the person ’ s chest , and press down firmly two or three times .  
 Person2:  Wait , what are you doing ! You can ’ t just kiss me then go for second base !
