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: What does the word prime generally suggest? 
 disfluent question: Which number is or actually what does the word prime generally suggest? 
 context: The concept of prime number is so important that it has been generalized in different ways in various branches of mathematics. Generally, prime indicates minimality or indecomposability, in an appropriate sense. For example, the prime field is the smallest subfield of a field F containing both 0 and 1. It is either Q or the finite field with p elements, whence the name. Often a second, additional meaning is intended by using the word prime, namely that any object can be, essentially uniquely, decomposed into its prime components. For example, in knot theory, a prime knot is a knot that is indecomposable in the sense that it cannot be written as the knot sum of two nontrivial knots. Any knot can be uniquely expressed as a connected sum of prime knots. Prime models and prime 3-manifolds are other examples of this type.
indecomposability
The proper question "What does the word prime generally suggest?" can be answered by reading the line "Generally, prime indicates minimality or indecomposability". The disfluent question "Which number is or actually what does the word prime generally suggest?" can also be answered in a similar manner. An answer to either of these questions would be "indecomposability", since that indicates what 'prime' suggests in general..
