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?

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