The graphic organizer shows three names: Jane Addams, Mark Twain, and Andrew Carnegie, with a question mark in the fourth box. To determine which name best completes the graphic organizer, we need to consider the relationships between these individuals.
Jane Addams was a prominent figure in the Progressive Era and is known for her work in social reform and women's suffrage. Mark Twain was a canonized writer famous for his novels and social commentary. Andrew Carnegie was a progressive industrialist and philanthropist.
Given these relationships, the best option to complete the graphic organizer is A. Progressive Industrialists.
