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: Of what form do Euler numbers take? 
 disfluent question: Of which or no make that of what form do Euler numbers take? 
 context: After the Greeks, little happened with the study of prime numbers until the 17th century. In 1640 Pierre de Fermat stated (without proof) Fermat's little theorem (later proved by Leibniz and Euler). Fermat also conjectured that all numbers of the form 22n + 1 are prime (they are called Fermat numbers) and he verified this up to n = 4 (or 216 + 1). However, the very next Fermat number 232 + 1 is composite (one of its prime factors is 641), as Euler discovered later, and in fact no further Fermat numbers are known to be prime. The French monk Marin Mersenne looked at primes of the form 2p − 1, with p a prime. They are called Mersenne primes in his honor.
[A]: None


[Q]: proper question: Some people describe what between individuals or groups as imperialism or colonialism? 
 disfluent question: Some people describe modern extension no they describe what between individuals or groups as imperialism or colonialism? 
 context: Some have described the internal strife between various people groups as a form of imperialism or colonialism. This internal form is distinct from informal U.S. imperialism in the form of political and financial hegemony. This internal form of imperialism is also distinct from the United States' formation of colonies abroad. Through the treatment of its indigenous peoples during westward expansion, the United States took on the form of an imperial power prior to any attempts at external imperialism. This internal form of empire has been referred to as internal colonialism. Participation in the African slave trade and the subsequent treatment of its 12 to 15 million Africans is viewed by some to be a more modern extension of America's internal colonialism. However, this internal colonialism faced resistance, as external colonialism did, but the anti-colonial presence was far less prominent due to the nearly complete dominance that the United States was able to assert over both indigenous peoples and African-Americans. In his lecture on April 16, 2003, Edward Said made a bold statement on modern imperialism in the United States, whom he described as using aggressive means of attack towards the contemporary Orient, due to their backward living, lack of democracy and the violation of women’s rights. The western world forgets during this process of converting the other that enlightenment and democracy are concepts that not all will agree upon.
[A]: internal strife


[Q]: proper question: Who was one of the most famous people born in Warsaw? 
 disfluent question: Where rather who was one of the most famous people born in Warsaw? 
 context: One of the most famous people born in Warsaw was Maria Skłodowska-Curie, who achieved international recognition for her research on radioactivity and was the first female recipient of the Nobel Prize. Famous musicians include Władysław Szpilman and Frédéric Chopin. Though Chopin was born in the village of Żelazowa Wola, about 60 km (37 mi) from Warsaw, he moved to the city with his family when he was seven months old. Casimir Pulaski, a Polish general and hero of the American Revolutionary War, was born here in 1745.
[A]:
Maria Skłodowska-Curie
