The correct answer is B, since that diagram best explains a cause and effect relationship that has shaped U.S. politics. In fact, restrictions on who can receive public campaign funds have contributed to the persistence of the two-party system.
Public funding of political campaigns in the United States is quite limited, so candidates end up going to private financing. This, in turn, only finances those who have real chances of getting the positions in the voting, which ends up closing the question between Democrats and Republicans, strengthening the two-party system.
Explanation:
The system of checks and balances in government was developed to ensure that no one branch of government would become too powerful. The framers of the U.S. Constitution built a system that divides power between the three branches of the U.S. government—legislative, executive and judicial—and includes various limits and controls on the powers of each branch.
All are tied up to a revolution that provided the lower class people new grounds to stand on. In the mist of the revolutions a sense of national pride is common place.
