Answer:
Insight.
Explanation:
As the exercise describes, the process or moment in which a solution to a hard problem comes to us is called insight. Like it happened to Jason, it may come to us at a later moment when we are meant to relax or do another thing. This is exactly an insight; to be able to see or understand something clearly, related with our intuition. Therefore, after Jason got stuck on a math problem he decided to have dinner and the moment of insight came to him when he was not thinking of that.
