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:     Balista , pull me a ristretto . 
 Person2:  What ? You're suddenly some kind of coffee snob now ? What's a ristretto anyway ? 
 Person1:      It's basically a very strong espresso . Half the water pulled through the same amount of beans . Pure coffee essence . 
 Person2:  Sounds like it must be just full of caffeine . I want one of those instead ! 
 Person1:      You fiend . It's about the flavor , not the fix . Why don't you just crush some caffeine pills and start doing lines ?
