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: Who wasn't given land by British goovernment for development of Ohio Country? 
 disfluent question: Who wasn't given land by British government for development of Iroquois no Ohio Country? 
 context: In 1749 the British government gave land to the Ohio Company of Virginia for the purpose of developing trade and settlements in the Ohio Country. The grant required that it settle 100 families in the territory, and construct a fort for their protection. But, as the territory was also claimed by Pennsylvania, both colonies began pushing for action to improve their respective claims. In 1750 Christopher Gist, acting on behalf of both Virginia and the company, explored the Ohio territory and opened negotiations with the Indian tribes at Logstown. He completed the 1752 Treaty of Logstown in which the local Indians, through their Half-King Tanacharison and an Iroquois representative, agreed to terms that included permission to build a strong house at the mouth of the Monongahela River (the site of present-day Pittsburgh, Pennsylvania). By the late 17th century, the Iroquois had pushed many tribes out of the Ohio Valley, and kept it as hunting ground by right of conquest.

Input: Consider Input: proper question: Where does the Rhine end? 
 disfluent question: Where does the Rhine begin or no I mean end? 
 context: The length of the Rhine is conventionally measured in Rhine-kilometers (Rheinkilometer), a scale introduced in 1939 which runs from the Old Rhine Bridge at Constance (0 km) to Hoek van Holland (1036.20 km). The river length is significantly shortened from the river's natural course due to number of canalisation projects completed in the 19th and 20th century.[note 7] The total length of the Rhine, to the inclusion of Lake Constance and the Alpine Rhine is more difficult to measure objectively; it was cited as 1,232 kilometres (766 miles) by the Dutch Rijkswaterstaat in 2010.[note 1]

Output: Hoek van Holland


Input: Consider Input: proper question: During what war did the Western Allies cross the Rhine bridge at Arnhem? 
 disfluent question: During which or no make that what war did the Western Allies cross the Rhine bridge at Arnhem? 
 context: In World War II, it was recognised that the Rhine would present a formidable natural obstacle to the invasion of Germany, by the Western Allies. The Rhine bridge at Arnhem, immortalized in the book, A Bridge Too Far and the film, was a central focus of the battle for Arnhem, during the failed Operation Market Garden of September 1944. The bridges at Nijmegen, over the Waal distributary of the Rhine, were also an objective of Operation Market Garden. In a separate operation, the Ludendorff Bridge, crossing the Rhine at Remagen, became famous, when U.S. forces were able to capture it intact – much to their own surprise – after the Germans failed to demolish it. This also became the subject of a film, The Bridge at Remagen. Seven Days to the River Rhine was a Warsaw Pact war plan for an invasion of Western Europe during the Cold War.
