Give evidence from the class materials such as the lectures/films and readings. (Outside sources are fine as long as they are reliable; that means up-to-date and vetted for accuracy of the facts, rather than just any old person writing whatever they want!)

What are the alternatives to states and hierarchy in today’s world; is egalitarianism even possible today?
