Answer:
Intrinsically motivated
Explanation:
Since Kevin was not enrolled in a school nor have a job that his mathematical reasoning would help him either pass a test or solve a problem at work, the reason for his motivation is driven by internal rewards. Hence Intrinsic motivation can be defined as a behavior, not driven by any external motivation, but by internal rewards. The motivation for Kevin wanting to learn mathematics on his own comes from within and is naturally satisfying to Kevin.
I would say HMO. The reason is it says SELECTED physicians. An HMO is an in network where you can only go to certain doctors and facilities. In return the doctors receive a little less than what they would originally be paid by other insurances. PPO's you can go to any doctor you want, however the insurance may not cover as much. Hope this helped. I would go with HMO.
