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.

Input: Consider Input: proper question: The Paris Palace had been an exceptional example of what type of architecture? 
 disfluent question: The Warsaw Philharmonic edifice, oh, I mean, the Paris Palace had been an exceptional example of what type of architecture? 
 context: Exceptional examples of the bourgeois architecture of the later periods were not restored by the communist authorities after the war (like mentioned Kronenberg Palace and Insurance Company Rosja building) or they were rebuilt in socialist realism style (like Warsaw Philharmony edifice originally inspired by Palais Garnier in Paris). Despite that the Warsaw University of Technology building (1899–1902) is the most interesting of the late 19th-century architecture. Some 19th-century buildings in the Praga district (the Vistula’s right bank) have been restored although many have been poorly maintained. Warsaw’s municipal government authorities have decided to rebuild the Saxon Palace and the Brühl Palace, the most distinctive buildings in prewar Warsaw.

Input: Consider Input: proper question: When did income inequality begin to decrease in the US? 
 disfluent question: When did income inequality begin to raise no sorry when did it start to decrease in the US? 
 context: Plotting the relationship between level of income and inequality, Kuznets saw middle-income developing economies level of inequality bulging out to form what is now known as the Kuznets curve. Kuznets demonstrated this relationship using cross-sectional data. However, more recent testing of this theory with superior panel data has shown it to be very weak. Kuznets' curve predicts that income inequality will eventually decrease given time. As an example, income inequality did fall in the United States during its High school movement from 1910 to 1940 and thereafter.[citation needed] However, recent data shows that the level of income inequality began to rise after the 1970s. This does not necessarily disprove Kuznets' theory.[citation needed] It may be possible that another Kuznets' cycle is occurring, specifically the move from the manufacturing sector to the service sector.[citation needed] This implies that it may be possible for multiple Kuznets' cycles to be in effect at any given time.

Input: Consider Input: proper question: When were plans for the Harris Friedman Institute announced? 
 disfluent question: When did the university so sorry when were plans for the Harris Friedman Institute announced? 
 context: From the mid-2000s, the university began a number of multimillion-dollar expansion projects. In 2008, the University of Chicago announced plans to establish the Milton Friedman Institute which attracted both support and controversy from faculty members and students. The institute will cost around $200 million and occupy the buildings of the Chicago Theological Seminary. During the same year, investor David G. Booth donated $300 million to the university's Booth School of Business, which is the largest gift in the university's history and the largest gift ever to any business school. In 2009, planning or construction on several new buildings, half of which cost $100 million or more, was underway. Since 2011, major construction projects have included the Jules and Gwen Knapp Center for Biomedical Discovery, a ten-story medical research center, and further additions to the medical campus of the University of Chicago Medical Center. In 2014 the University launched the public phase of a $4.5 billion fundraising campaign. In September 2015, the University received $100 million from The Pearson Family Foundation to establish The Pearson Institute for the Study and Resolution of Global Conflicts and The Pearson Global Forum at the Harris School of Public Policy Studies.
