Cleisthenes changed the basis of representation from family groups to territorial areas, and he gave full rights to all free men. Ten committees were given the rights to declare war, collect money, and check the authority of those in power. By secret vote, the people could shut off from society anyone who neglected his duty or seemed to be taking too much power. The ancient Romans believed that the common people should have a voice in the government. The people were entitled to elect representatives to govern themselves. The head of state was called the consul. The Romans required two men to hold the office of consul at the same time to keep any one person from getting too much power. The Romans also established a code of law called the Twelve Tables. The tables were the first step toward a government that granted rights to the citizens. Which of the following statements applies to both passages? The development of governments is a recent development in human history. Problems that are not addressed by a government will cause the government to collapse. As societies increased in complexity, the complexity of governments also increased. The need for governments to manage people's activities has diminished since ancient times.
