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.

proper question: Of what form are Mersenne tests?
disfluent question: Of what form are Mersenne primes oh I mean tests?
context: are prime. Prime numbers of this form are known as factorial primes. Other primes where either p + 1 or p 1 is of a particular shape include the Sophie Germain primes (primes of the form 2p + 1 with p prime), primorial primes, Fermat primes and Mersenne primes, that is, prime numbers that are of the form 2p 1, where p is an arbitrary prime. The LucasLehmer test is particularly fast for numbers of this form. This is why the largest known prime has almost always been a Mersenne prime since the dawn of electronic computers.
