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:     How do you usually get to school ?  
 Person2:  I usually ride my bike . Which form of transport do you prefer to use ?  
 Person1:      I feel that I can see more when I pedal a bicycle , but when I feel lazy , I drive my car .  
 Person2:  I think we should discourage people from using their private cars . They produce too much pollution !  
 Person1:      I agree , but I would find it difficult to stop using my car . It's just so convenient .  
 Person2:  Cars might be convenient , but they're so bad for the environment .  
 Person1:      Do you have a car ?  
 Person2:  No . I used to have one though . Once I started using my bicycle to get around , I found that I didn't really need it .  
 Person1:      Maybe if I sold my car now , I wouldn't be so tempted to use it .  
 Person2:  You could try . It would save you a lot of money .  
 Person1:      That's true . Every month , I spend hundreds of dollars on gas , insurance , and repairs .  
 Person2:  If you got to class by riding a bicycle every day instead of driving , you will get lots of exercise , too !  
 Person1:      I could stand to lose a few pounds . Having a car has made me lazy . I never end up walking anywhere !  
 Person2:  Let's go to a car dealership . I'll help you try to sell your car for a good price .  
 Person1:      Sounds good ! Let's go !
