Read the excerpt from "On Becoming an Inventor" by Dean Kamen.
When I was twelve years old and Barton, my older
brother, was around fifteen, we took over the family
basement. At first, I made a darkroom for developing
pictures, and Bart was using it as his lab where he was
raising about one hundred white rats, removing their
thymus glands, and trying to figure out the glands'
dysfunction. He wanted pictures taken of his experiment,
doing the surgery on rats, and since I already had a
darkroom, I took the pictures, though somewhat
reluctantly. I didn't like the blood.
What can you conclude about Barton from the excerpt?
He was interested in solving medical mysteries at a
rather early age.
He did not understand why Dean would be
squeamish about the blood.
He went on to become a very famous and successful
doctor.
He had a severe dislike for rats and all other kinds of
rodents.
