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.
One example is below.
Q: 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.
A: None
Rationale: 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.
Q: proper question: Who along with Russia supported post WW-I communist movements?
disfluent question: Who along with China, scratch that, Russia supported post WW-I communist movements?
context: Bolshevik leaders had effectively reestablished a polity with roughly the same extent as that empire by 1921, however with an internationalist ideology: Lenin in particular asserted the right to limited self-determination for national minorities within the new territory. Beginning in 1923, the policy of Indigenization [korenizatsiia] was intended to support non-Russians develop their national cultures within a socialist framework. Never formally revoked, it stopped being implemented after 1932. After World War II, the Soviet Union installed socialist regimes modeled on those it had installed in 191920 in the old Tsarist Empire in areas its forces occupied in Eastern Europe. The Soviet Union and the People's Republic of China supported postWorld War II communist movements in foreign nations and colonies to advance their own interests, but were not always successful.
