What is one of the core principles of the Constitution?

One of the core principles of the Constitution is to ensure the separation of powers. This principle is fundamental to the functioning of the American government as it establishes three distinct branches: the legislative, executive, and judicial branches. Each branch has its own responsibilities and powers, ensuring that no single branch becomes too powerful. This system of checks and balances allows each branch to monitor and limit the actions of the others, promoting accountability and fairness in governance. The separation of powers is designed to protect individual liberties and prevent tyranny, laying a foundation for a democratic society.

The other choices do not reflect the fundamental characteristics of the Constitution. For example, the idea of being inflexible and unchangeable contradicts the Constitution's provision for amendments, which allows for adaptability and change over time. Similarly, protecting a monarchy does not align with the democratic principles upon which the Constitution was built, as it established a republic rather than a monarchy. Lastly, the notion that the Constitution is meant only to benefit the wealthy ignores its purpose of serving all citizens and establishing equality under the law. The separation of powers directly addresses these aims and objectives by safeguarding democratic governance.
