3. which idea of henry david thoreau was adopted by twentieth-century leaders of great social change movements
a. individualism
b. inner light
c. different drummer theory
d. disobedience

The correct answer is D.

Henry David Thoreau was an American essayist, poet, philosopher, naturalist, development critic and historian. He is best known as the author of the book 'Walden' which is a reflection on simple living in natural surroundings. His essay 'Disobedience' is an argument for disobedience to a state that is unfair, and an incentive to improve the government.

Thoreau writings, especially the political ones, had very little impact on society during his lifetime. He was seen mostly as a naturalist and not as a theorist or a radical thinker.

After his death in 1862, his writings went to influence many important political figures and leaders such as : Mohandas Gandhi, President John F. Kennedy, Martin Luther King Jr., or the Russian author Leo Tolstoy.

They all stressed Thoreau's importance as a thinker of a state that is free and fair, an idea they supported and promoted themselves.
