Answer:
Theodore Roosevelt, Ida Tarbell, and W.E.B. Dubois were similar in their dedication to social and political reform in the early 20th century. Roosevelt, as a progressive president, pushed for government regulation of big business and conservation efforts. Tarbell, as a muckraking journalist, exposed corruption and unethical practices in the oil industry. Dubois, as a civil rights activist and scholar, advocated for equal rights for African Americans and fought against segregation and discrimination. All three figures were influential in their respective fields and sought to bring about positive change in American society.
