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:     Have you read all these crazy things that are going on around the world ? 
 Person2:  What do you mean ? 
 Person1:      I was reading about how some people get tricked or drugged in their hotel rooms and have their organs removed ! Then they are sold on the black market . 
 Person2:  Don't tell me you actually believe all that ? Don't be so gullible , they are just urban legends . They are just stories people make up to scare you . 
 Person1:      Well , I was also reading about how some popular songs have subliminal or even satanic messages if you play them backwards ! Can you believe that ? 
 Person2:  You really think an artist or song writer is going to go through the trouble of putting subliminal or satanic messages in a song ? Don't be so naive ! 
 Person1:      Well maybe you are right , but how about the story of how KFC has rows of headless chickens which are super grown in order to get bigger chickens faster ! 
 Person2:  Sounds a bit too far fetched to be true , don't you think ?
