which detail from “thomas edison: the master of improvement” supports the big-picture idea of the passage?

1.thomas edison is well known as a great inventor. however, he was also a fantastic improver.

2.unlike davy and swan, edison had no formal schooling. he was quite sickly as a child, so his mom taught him at home.

3.that way, all of those long-lasting edison bulbs would have a ready supply of the electricity they required.

4.edison himself probably summed it up best when he said, “genius is one percent inspiration and ninety-nine percent perspiration.”
