What does the system of checks and balances require from government branches?

The correct answer highlights that the system of checks and balances establishes a framework in which each branch of government can exercise oversight over the others to ensure that no single branch becomes too powerful. This mutual oversight is essential for maintaining a balance of power, as it fosters accountability and prevents the misuse of authority. Each branch—executive, legislative, and judicial—has specific powers that can limit or check the others. For instance, the legislative branch can pass laws, but the executive has the power to veto those laws, and the judiciary can interpret them. This interconnected relationship is crucial for the function of democracy and the protection of individual rights, ensuring that power is not concentrated in any one branch. This system is fundamental to the U.S. government as it promotes fairness and prevents tyranny.
