Final answer:
In a democracy, citizens directly influence the government by voting for their leaders, which is the form of government that allows the most citizen involvement in selecting leadership.
Step-by-step explanation:
In democracy, citizens play an important role in choosing leaders through voting. Democracies are in contrast to other forms of governments such as autocracies, oligarchies, and theocracies. An oligarchy is a form of government where a small group of elite people hold political power, and the citizens have very limited role in the election process. In the United States, we observe a form of democracy known as a representative democracy, where citizens elect representatives who then make policy decisions on their behalf. This differs from a direct democracy, where citizens would vote on policies directly.
Monarchies can be absolute, where the monarch has unrestricted power, or constitutional, where the monarch's powers are regulated by a constitution. Some monarchies start as absolute and evolve into constitutional forms. Totalitarian government and dictatorship are more extreme forms of autocracy where citizens have even less control over their leaders and government policy than in monarchies or oligarchies.
