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:     What do you think is harder , reading or writing ?  
 Person2:  Well , they ’ re completely different . Reading is passive , and writing is active .  
 Person1:      I don ’ t think I understand what you mean . Could you explain a little more ?  
 Person2:  In reading you need to recognize language by seeing the words on the page and knowing what they are . In writing you have to produce language , you have to create your own words on a blank page .  
 Person1:      Oh , now I see what you mean . When you ’ re reading , you are just looking , but when you are writing , you are actually doing something !  
 Person2:  A reading knowledge of a language is larger and different from a writing knowledge . Don ’ t you think so ?  
 Person1:      I think I see what you mean . I can read Shakespeare but I definitely can ’ t write it .  
 Person2:  Exactly .  
 Person1:      So I have another question for you . What do you think is harder , speaking or understanding ?  
 Person2:  They ’ re both harder than reading or writing .  
 Person1:      In what way ?  
 Person2:  Because they are direct communication with another person , and there ’ s a time limit . This time limit is the most serious problem for foreigners , even for those who know lots of English .  
 Person1:      You are making me feel really discouraged .  
 Person2:  I ’ m not trying to discourage you . I ’ m trying to help you . You have to live with these difficulties . Isn ’ t it better to know about them ? The more you know about what you have to face , the better you ’ ll do . I promise !
