Teacher: Use a disfluent question or a proper question and find the answer to the question based on the given context or return None if an answer can't be found. A disfluent question is a question that has some interruptions in it while framing. A proper question is the correct form of the question without any disfluency.
Teacher: Now, understand the problem? If you are still confused, see the following example:
proper question: In what year did the U of C become one of 7 founding members of the Association of Chicago Universities? 
 disfluent question: In what year did Robert Harper or did the U of C become one of 7 founding members of the Association of Chicago Universities? 
 context: Founded by the American Baptist Education Society with a donation from oil magnate and wealthiest man in history John D. Rockefeller, the University of Chicago was incorporated in 1890; William Rainey Harper became the university's first president in 1891, and the first classes were held in 1892. Both Harper and future president Robert Maynard Hutchins advocated for Chicago's curriculum to be based upon theoretical and perennial issues rather than on applied sciences and commercial utility. With Harper's vision in mind, the University of Chicago also became one of the 14 founding members of the Association of American Universities, an international organization of leading research universities, in 1900.
Solution: None
Reason: The answer to the above question is not found from the context hence it is not answerable so the output is 'None' so it is a positive example.

Now, solve this instance: proper question: Revolutionary civil disobedience towards culture is highlighted by example of who? 
 disfluent question: Revolutionary civil disobedience towards culture is highlighted by example of what or make that of who? 
 context: Non-revolutionary civil disobedience is a simple disobedience of laws on the grounds that they are judged wrong by an individual conscience, or as part of an effort to render certain laws ineffective, to cause their repeal, or to exert pressure to get one's political wishes on some other issue. Revolutionary civil disobedience is more of an active attempt to overthrow a government (or to change cultural traditions, social customs, religious beliefs, etc...revolution doesn't have to be political, i.e. cultural revolution, it simply implies sweeping and widespread change to a section of the social fabric). Gandhi's acts have been described as revolutionary civil disobedience. It has been claimed that the Hungarians under Ferenc Deák directed revolutionary civil disobedience against the Austrian government. Thoreau also wrote of civil disobedience accomplishing peaceable revolution. Howard Zinn, Harvey Wheeler, and others have identified the right espoused in The Declaration of Independence to alter or abolish an unjust government to be a principle of civil disobedience.
