Read the excerpt from "On Becoming an Inventor" by Dean Kamen. From this well-stocked basement came a whole new set of really neat projects. My younger brother, Mitch, and his friends, as well as some of my own friends, would come after school to help. At sixteen I was now a young entrepreneur, paying them for their help. I was surprised by the number of orders I was getting for more and more equipment. Soon I didn't have time to build and design new things. Giving over this work to other kids gave me more time to do what I wanted to do. This went on after school and all summer long.

Which fact from the excerpt best supports Kamen’s opinion that his projects were neat?

The basement was well-stocked with equipment.
Mitch and his friends would come over after school.
He was getting a large number of orders for the projects.
He gave over some of the work to the other kids.
