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 do MSPs who are not in the chamber when the division bell rings return to do? 
 disfluent question: What do MSPs who are not in the chamber when the dissent instead maybe division bell rings return to do? 
 context: Each sitting day, normally at 5 pm, MSPs decide on all the motions and amendments that have been moved that day. This Decision Time is heralded by the sounding of the division bell, which is heard throughout the Parliamentary campus and alerts MSPs who are not in the chamber to return and vote. At Decision Time, the Presiding Officer puts questions on the motions and amendments by reading out the name of the motion or amendment as well as the proposer and asking Are we all agreed?, to which the chamber first votes orally. If there is audible dissent, the Presiding Officer announces There will be a division and members vote by means of electronic consoles on their desks. Each MSP has a unique access card with a microchip which, when inserted into the console, identifies them and allows them to vote. As a result, the outcome of each division is known in seconds.

Solution: vote
