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.

Let me give you an 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.
The answer to this example can be: None
Here is why: 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.

OK. solve this:
proper question: Where did the French send a large number of settlers? 
 disfluent question: In what country did the French send a large number of settlers? 
 context: It became a moral justification to lift the world up to French standards by bringing Christianity and French culture. In 1884 the leading exponent of colonialism, Jules Ferry declared France had a civilising mission: The higher races have a right over the lower races, they have a duty to civilize the inferior. Full citizenship rights – ‘’assimilation’’ – were offered, although in reality assimilation was always on the distant horizon. Contrasting from Britain, France sent small numbers of settlers to its colonies, with the only notable exception of Algeria, where French settlers nevertheless always remained a small minority.
Answer:
Algeria
