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 are you reading ? 
 Person2:  It ’ s an article about language . It talks about the idea of having a single global language . 
 Person1:      It seems that English already is the main global language . Does the article suggest that there should be an artificial language like Esperanto as the world language . 
 Person2:  Actually , it suggest English . The main argument is that English is already being studied as a second language in most countries-china , India , mexico , Nigeria , Pakistan , and japan . So beginning again with a language like Esperanto would be wasteful . The second argument is that English is used in modern technology far more that any other language . Most emails are sent in English and the vast majority of website use English . 
 Person1:      Does the article say anything about other language ? How will they survive in an English-speaking world ? 
 Person2:  The article points out that many languages have been lost and will be lost , but others will continue to be used for generation , even if English continues to be the dominant language . 
 Person1:      Right . All the people who speak Chinese . Hindi , French and Spanish aren ’ t suddenly going to stop using those languages . 
 Person2:  Exactly . The article suggests that those languages will be used , but that they will only rarely be used in international communication between non-native speakers . 
 Person1:      In that case , I shall continue to learning a few basic phrases in other languages .
