What is a key principle stated in the Constitution?

The principle of separation of powers is a foundational concept in the U.S. Constitution, designed to prevent any one branch of government from becoming too powerful. This structure divides the government into three distinct branches: legislative, executive, and judicial. Each branch has its own responsibilities and powers, along with checks and balances to ensure that they can limit each other's authority. This framework promotes a system of governance where power is distributed and balanced, safeguarding against tyranny and ensuring that authority is exercised in a responsible manner.

While the other options contain elements of democratic values or governance, they do not reflect the structural principles explicitly stated in the Constitution. The phrase "all men are created equal" is derived from the Declaration of Independence, not the Constitution itself. The idea of government having unlimited power contradicts the very principles of American democracy, which is built upon limited government. Lastly, the notion that citizens should be educated by the government is not a constitutional principle but rather a policy decision that can vary over time and context.
