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 Q]: proper question: What was New Briton's response to Celeron? 
 disfluent question: What was New Briton's arrival no response to Celeron? 
 context: When Céloron's expedition arrived at Logstown, the Native Americans in the area informed Céloron that they owned the Ohio Country and that they would trade with the British regardless of the French. Céloron continued south until his expedition reached the confluence of the Ohio and the Miami rivers, which lay just south of the village of Pickawillany, the home of the Miami chief known as Old Briton. Céloron threatened Old Briton with severe consequences if he continued to trade with the British. Old Briton ignored the warning. Disappointed, Céloron returned to Montreal in November 1749.

[EX Q]: proper question: Of what mathematical nature is the prime problem? 
 disfluent question: What function is related to Basel numbers or wait tell me what kind of mathematical nature prime problems are? 
 context: The zeta function is closely related to prime numbers. For example, the aforementioned fact that there are infinitely many primes can also be seen using the zeta function: if there were only finitely many primes then ζ(1) would have a finite value. However, the harmonic series 1 + 1/2 + 1/3 + 1/4 + ... diverges (i.e., exceeds any given number), so there must be infinitely many primes. Another example of the richness of the zeta function and a glimpse of modern algebraic number theory is the following identity (Basel problem), due to Euler,

[EX Q]: proper question: What does the large pharynx do in the Beroe when its not feeding? 
 disfluent question: What does the, oh actually, what does the large pharynx do in the Beroe when its not feeding? 
 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.
