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.
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.
Example solution: None
Example explanation: 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.

Problem: proper question: What action did Brownlee take against GCSB Waihopai that caused them to close temporarily?
disfluent question: What action did Brownlee take against civil disobedience um wait no GCSB Waihopai that caused them to close temporarily?
context: Some forms of civil disobedience, such as illegal boycotts, refusals to pay taxes, draft dodging, distributed denial-of-service attacks, and sit-ins, make it more difficult for a system to function. In this way, they might be considered coercive. Brownlee notes that although civil disobedients are constrained in their use of coercion by their conscientious aim to engage in moral dialogue, nevertheless they may find it necessary to employ limited coercion in order to get their issue onto the table. The Plowshares organization temporarily closed GCSB Waihopai by padlocking the gates and using sickles to deflate one of the large domes covering two satellite dishes.
Solution: None
