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: By what means is imperialism never administered? 
 disfluent question: By what means is imperialism always or wait never administered? 
 context: Imperialism is a type of advocacy of empire. Its name originated from the Latin word imperium, which means to rule over large territories. Imperialism is a policy of extending a country's power and influence through colonization, use of military force, or other means. Imperialism has greatly shaped the contemporary world. It has also allowed for the rapid spread of technologies and ideas. The term imperialism has been applied to Western (and Japanese) political and economic dominance especially in Asia and Africa in the 19th and 20th centuries. Its precise meaning continues to be debated by scholars. Some writers, such as Edward Said, use the term more broadly to describe any system of domination and subordination organised with an imperial center and a periphery.

Input: Consider Input: proper question: Where is the office of Edward Harkness located? 
 disfluent question: Where is the office of State House no of Edward Harkness located? 
 context: Harvard's 209-acre (85 ha) main campus is centered on Harvard Yard in Cambridge, about 3 miles (5 km) west-northwest of the State House in downtown Boston, and extends into the surrounding Harvard Square neighborhood. Harvard Yard itself contains the central administrative offices and main libraries of the university, academic buildings including Sever Hall and University Hall, Memorial Church, and the majority of the freshman dormitories. Sophomore, junior, and senior undergraduates live in twelve residential Houses, nine of which are south of Harvard Yard along or near the Charles River. The other three are located in a residential neighborhood half a mile northwest of the Yard at the Quadrangle (commonly referred to as the Quad), which formerly housed Radcliffe College students until Radcliffe merged its residential system with Harvard. Each residential house contains rooms for undergraduates, House masters, and resident tutors, as well as a dining hall and library. The facilities were made possible by a gift from Yale University alumnus Edward Harkness.

Input: Consider Input: proper question: What experiment can be performed on large settings that cannot be on small settings? 
 disfluent question: What type of study is no scratch that what experiment can be performed on large settings that cannot be on small settings? 
 context: Structural geologists use microscopic analysis of oriented thin sections of geologic samples to observe the fabric within the rocks which gives information about strain within the crystalline structure of the rocks. They also plot and combine measurements of geological structures in order to better understand the orientations of faults and folds in order to reconstruct the history of rock deformation in the area. In addition, they perform analog and numerical experiments of rock deformation in large and small settings.
