Detailed Instructions: 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.
See one example below:
Problem: 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

Problem: proper question: What else contributes to Jacksonville's summer storms other than land heating beside the water? 
 disfluent question: Where else no uh make that what else contributes to Jacksonville's summer storms other than land heating beside the water? 
 context: Mean monthly temperatures range from around 53 F in January to 82 F in July. High temperatures average 64 to 92 °F (18 to 33 °C) throughout the year. High heat indices are common for the summer months in the area, with indices above 110 °F (43.3 °C) possible. The highest temperature recorded was 104 °F (40 °C) on July 11, 1879 and July 28, 1872. It is common for thunderstorms to erupt during a typical summer afternoon. These are caused by the rapid heating of the land relative to the water, combined with extremely high humidity.
Solution:
high humidity
