Which detail from "Thomas Edison: The Master of Improvement” supports the big-picture idea of the passage?
Humphry Davy created the first electric light and shared his design with Edison.
Unlike Davy and Swan, Edison had no formal schooling. He was quite sickly as a child, so his mom taught him at home.
That way, all of those long-lasting Edison bulbs would have a ready supply of the electricity they required.
Edison was successful because he persevered through challenges to reach his goal of creating a practical lightbulb
Answers
Answer:
Joseph Swan experimented using carbon paper filaments, while Edison used metallic filaments initially.
Swan received a formal education, while Edison did not.
Explanation:
In 1850, Swan started working on a lamp by using a carbonized paper filament.
He used the evacuated glass tube and after ten years, was able to present his work in 1860. However, the bulb had a short life span but it had good efficiency in working.
Edison was also experimenting with metallic filament but it took him a lot of energy and attempts to make an ideal filament.

Answer:
The detail that Edison bulbs would have a ready supply of electricity supports the big-picture idea of the passage.
Explanation:
Thomas Alva Edison was born on February 11, 1847, in Milan, Ohio; the seventh and last child of Samuel and Nancy Edison. When Edison was seven his family moved to Port Huron, Michigan. Edison lived here until he struck out on his own at the age of sixteen. Edison had little or no formal education as a child, attending school just for a few months. He was taught reading, writing, and arithmetic by his mother, but was always a really curious child and taught himself much by reading on his own. This belief in self-improvement remained throughout his life.
Edison began performing at an early age, as most boys did at the time. At thirteen he took employment as a newsboy, selling newspapers and candy on the local railroad that ran through Port Huron to Detroit. He seems to possess spent much of his free time reading scientific, and technical books, and also had the chance at this time to learn how to operate a telegraph. By the time he was sixteen, Edison was proficient enough to figure as a telegrapher full-time.
