Read the passage and then answer the question.

Dr. Martin Luther King, Jr., was one of the foremost figures during America's civil rights movement. In fact, many consider him to be one of the greatest leaders of the twentieth century. He pushed for African Americans to have the same rights as white citizens, including equal access to both public and private facilities, such as schools, workplaces, stores, and restaurants. Also a skilled orator, Dr. King is perhaps best known for his "I Have a Dream" speech, which he delivered during the March on Washington in 1963.
While other civil rights groups at the time were willing to use "any means necessary" to bring about change, Dr. King was an advocate of nonviolent action. He encouraged peaceful protest and was even awarded a Nobel Peace Prize at the strikingly young age of thirty-five. Sadly, Dr. King was killed in 1968. Still, his message of equal rights for all people and his teachings of peace live on in posterity; in the years since, Americans have continued to work towards his dream.
