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.

Q: proper question: What do bacteria use to move proteins from the host to the pathogen? 
 disfluent question: What do bacteria use to move proteins from the host to the barrier, sorry, pathogen? 
 context: The success of any pathogen depends on its ability to elude host immune responses. Therefore, pathogens evolved several methods that allow them to successfully infect a host, while evading detection or destruction by the immune system. Bacteria often overcome physical barriers by secreting enzymes that digest the barrier, for example, by using a type II secretion system. Alternatively, using a type III secretion system, they may insert a hollow tube into the host cell, providing a direct route for proteins to move from the pathogen to the host. These proteins are often used to shut down host defenses.

Q: proper question: J. A. Hobson didn't want which races to develop the world? 
 disfluent question: J. A. Ratzel oops I mean Hobson didn't want which races to develop the world? 
 context: A controversial aspect of imperialism is the defense and justification of empire-building based on seemingly rational grounds. J. A. Hobson identifies this justification on general grounds as: It is desirable that the earth should be peopled, governed, and developed, as far as possible, by the races which can do this work best, i.e. by the races of highest 'social efficiency'. Many others argued that imperialism is justified for several different reasons. Friedrich Ratzel believed that in order for a state to survive, imperialism was needed. Halford Mackinder felt that Great Britain needed to be one of the greatest imperialists and therefore justified imperialism. The purportedly scientific nature of Social Darwinism and a theory of races formed a supposedly rational justification for imperialism. The rhetoric of colonizers being racially superior appears to have achieved its purpose, for example throughout Latin America whiteness is still prized today and various forms of blanqueamiento (whitening) are common.

Q: proper question: How was Sadat rewarded by the Islamists for his attempts to keep Egypt from being in modern times and civilization? 
 disfluent question: How was the Soviet Union no sorry Sadat rewarded by the Islamists for his attempts to keep Egypt from being in modern times and civilization? 
 context: Egyptian President Anwar Sadat – whose policies included opening Egypt to Western investment (infitah); transferring Egypt's allegiance from the Soviet Union to the United States; and making peace with Israel – released Islamists from prison and welcomed home exiles in tacit exchange for political support in his struggle against leftists. His encouraging of the emergence of the Islamist movement was said to have been imitated by many other Muslim leaders in the years that followed.  This gentlemen's agreement between Sadat and Islamists broke down in 1975 but not before Islamists came to completely dominate university student unions. Sadat was later assassinated and a formidable insurgency was formed in Egypt in the 1990s. The French government has also been reported to have promoted Islamist preachers in the hope of channeling Muslim energies into zones of piety and charity.
