Thomas Edison is most commonly associated with inventing the electric light bulb, but that singular piece of trivia does not do justice to Edison' s unrivaled contributions to the Industrial Revolution in the United States. Often called "The Wizard of Menlo Park", Edison applied cutting-edge business principles, like mass production, to the field of science for the first time, including creating the world' s first industrial research laboratory. Edison also developed a power grid capable of generating and distributing power to homes and factories. A prolific inventor, Edison invented the phonograph and motion picture camera, and he held more than one thousand patents in the United States. Which of the following best describes the conclusion set forth by the author? ['The Industrial Revolution in the United States would not have happened without Thomas Edison.', 'Thomas Edison was a prolific inventor.', 'Thomas Edison is one of the most important figures in American history.', 'Common knowledge does not do justice to the legacy of Thomas Edison.']
