Read the excerpt from "On Becoming An Inventor" by Dean Kamen. I had just finished making a complicated piece of equipment that was to be used for a show opening in Philadelphia called "Fiorello." When the machine arrived they had trouble wiring it, so instead of going off to college that morning for an orientation, I spent several days at the theater fixing my light/sound equipment. The show received poor reviews, except for the mention by one reviewer of the "special effects," which, he wrote, were "outstanding."

A. It was used for a show in Philadelphia called "Fiorello."
B. The show technicians had trouble wiring the equipment.
C. The show received poor reviews from the critics.
D. A reviewer wrote that the special effects were outstanding.
