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.

Ex Input:
proper question: What was not thought to decide a person's behavior?
disfluent question: What were er what was not thought to decide a person's behavior?
context: The concept environmental determinism served as a moral justification for domination of certain territories and peoples. It was believed that a certain person's behaviours were determined by the environment in which they lived and thus validated their domination. For example, people living in tropical environments were seen as less civilized therefore justifying colonial control as a civilizing mission. Across the three waves of European colonialism (first in the Americas, second in Asia and lastly in Africa), environmental determinism was used to categorically place indigenous people in a racial hierarchy. This takes two forms, orientalism and tropicality.

Ex Input:
proper question: What non-Japanese empire did the Yuan dynasty succeed?
disfluent question: Which non-Chinese or no make that non-Japanese empire did the Yuan dynasty succeed?
context: The Yuan dynasty is considered both a successor to the Mongol Empire and an imperial Chinese dynasty. It was the khanate ruled by the successors of Mongke Khan after the division of the Mongol Empire. In official Chinese histories, the Yuan dynasty bore the Mandate of Heaven, following the Song dynasty and preceding the Ming dynasty. The dynasty was established by Kublai Khan, yet he placed his grandfather Genghis Khan on the imperial records as the official founder of the dynasty as Taizu.[b] In the Proclamation of the Dynastic Name (), Kublai announced the name of the new dynasty as Great Yuan and claimed the succession of former Chinese dynasties from the Three Sovereigns and Five Emperors to the Tang dynasty.

Ex Input:
proper question: According to Gluga's theorem, what period does 1/p always have assuming p is a prime that is not 2 or 5?
disfluent question: According to Fermat's theorem, what period does 1/p always have assuming p is a prime that is not 2 or 5 no wait tell me the answer based on Gluga's theorem?
context: Giuga's conjecture says that this equation is also a sufficient condition for p to be prime. Another consequence of Fermat's little theorem is the following: if p is a prime number other than 2 and 5, 1/p is always a recurring decimal, whose period is p 1 or a divisor of p 1. The fraction 1/p expressed likewise in base q (rather than base 10) has similar effect, provided that p is not a prime factor of q. Wilson's theorem says that an integer p > 1 is prime if and only if the factorial (p 1)! + 1 is divisible by p. Moreover, an integer n > 4 is composite if and only if (n 1)! is divisible by n.
