Teacher: Convert a disfluent question to a proper question. 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.
Teacher: Now, understand the problem? If you are still confused, see the following example:
Why was uh where was the Rhine regulated with an upper canal?
Solution: Where was the Rhine regulated with an upper canal?
Reason: The above disfluent question is correctly converted to a proper question. The 'uh' and the 'why' before the correction should be removed to make it fluent.

Now, solve this instance: Which hypothesis no conjecture holds that every even integer n greater than 2 can be expressed as a sum of two primes?
Student:
