Michael is a successful business owner who can develop his ideas into productive enterprises. although he was an average student in school, his great social skills and common sense indicate that michael might score highly in what sternberg calls intelligence.

I believe the answer is: practical

practical intelligence refers to a form of intelligence that is created by experiencing a certain things directly rather than observing it. Example of this would be intelligence needed to be good at soccer. You would not be a great soccer player by watching the professional game. You would be great at it if you practice the soccer over and over again.
