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 Input: proper question: What's Thomas Piketty's job?
disfluent question: What haven't or uh what's Thomas Piketty's job?
context: Studies on income inequality and growth have sometimes found evidence confirming the Kuznets curve hypothesis, which states that with economic development, inequality first increases, then decreases. Economist Thomas Piketty challenges this notion, claiming that from 1914 to 1945 wars and violent economic and political shocks reduced inequality. Moreover, Piketty argues that the magical Kuznets curve hypothesis, with its emphasis on the balancing of economic growth in the long run, cannot account for the significant increase in economic inequality throughout the developed world since the 1970s.
Example Output: Economist

Example Input: proper question: What proposed attacks did Shirley plan?
disfluent question: Who or no make that what proposed attacks did Shirley plan?
context: Following the death of Braddock, William Shirley assumed command of British forces in North America. At a meeting in Albany in December 1755, he laid out his plans for 1756. In addition to renewing the efforts to capture Niagara, Crown Point and Duquesne, he proposed attacks on Fort Frontenac on the north shore of Lake Ontario and an expedition through the wilderness of the Maine district and down the Chaudiere River to attack the city of Quebec. Bogged down by disagreements and disputes with others, including William Johnson and New York's Governor Sir Charles Hardy, Shirley's plan had little support.
Example Output: capture Niagara, Crown Point and Duquesne, he proposed attacks on Fort Frontenac on the north shore of Lake Ontario

Example Input: proper question: What do epithelial cells have at the oral end?
disfluent question: What do streamlines have at the oral end no what do epithelial cells have at the oral end?
context: The Beroida, also known as Nuda, have no feeding appendages, but their large pharynx, just inside the large mouth and filling most of the saclike body, bears macrocilia at the oral end. These fused bundles of several thousand large cilia are able to bite off pieces of prey that are too large to swallow whole almost always other ctenophores. In front of the field of macrocilia, on the mouth lips in some species of Beroe, is a pair of narrow strips of adhesive epithelial cells on the stomach wall that zip the mouth shut when the animal is not feeding, by forming intercellular connections with the opposite adhesive strip. This tight closure streamlines the front of the animal when it is pursuing prey.
Example Output:
None
