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: Are you ready to go the concert ?
Person2: Yes . Should we go there by bus so we aren't late ?
Person1: Actually , why don't we go there by bike ? We could get stuck in traffic if we travel by bus in rush hour .
Person2: That's true . Cycling is good for our environment , too . Let me just get my helmet then .
Person1: Is your helmet comfortable ?
Person2: Not really , but I liked the design , so I got it .
Person1: Maybe you should think about getting a round helmet ; they're better .
Person2: I'll think about it .
Person1: Is that your new bicycle ?
Person2: Yes , my father gave it to me for my birthday . Do you like it ?
Person1: It's the newest 10 speed cycling mountain bike . These are really expensive !
Person2: Nothing but the best from my dad . I like everything about it except for the brakes . They are a bit sticky .
Person1: I can fix those for you . Is there anything else wrong with it ?
Person2: Well , my saddle is too low for me . Do you know how to change the height ?
Person1: That's easy . It's important to have the saddle high enough so that your legs can extend fully when you are on your bicycle .
Person2: Is that why my knees have felt sore after every time I've ridden my bike ?
Person1: It's possible . Give me a minute and I can fix these for you and then we can go .
