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:     I ’ Ve always wondered , what ’ s the difference between English for Chinese students and English for native students ?  
 Person2:  I don ’ t know . What do you think ?  
 Person1:      I think a Chinese student concentrates on written English , and uses it as a basis for communicating . From start to finish he ’ s learning vocabulary and fundamentals of grammar . This is a very difficult way to learn .  
 Person2:  What do natives get ?  
 Person1:      They get higher level English , which is more formal than everyday spoken English . They also deal with matters of style and creativity .  
 Person2:  Do you mean that a native doesn ’ t make any mistakes in grammar ?  
 Person1:      Absolutely not ! Native speakers make a lot of grammar mistakes , especially if they come from a home where nonstandard English is spoken .  
 Person2:  I suppose that only a small percentage of college students don ’ t know standard English in American universities .  
 Person1:      Actually there are more non-native speakers than you think . That ’ s why it ’ s so important to quit worrying about making mistakes . Just talk to everyone every chance you get .
