What is one function of the Constitution?

One function of the Constitution is to set up the government. This foundational document outlines the structure and powers of the various branches of government, including the legislative, executive, and judicial branches. It establishes the framework for how these branches operate and interact with one another, providing a system of checks and balances intended to prevent any one branch from becoming too powerful. This organization is crucial for maintaining order and protecting the rights of citizens.

The other options, while they may relate to important historical or procedural contexts, do not directly pertain to the role of the Constitution itself in establishing a government framework. The declaration of independence pertains to the separation from British rule, while defining the Constitution itself refers to the nature of the document rather than its operational purpose. Additionally, while the Constitution does allow for the creation of state governments, its primary role is to unify and structure the federal government distinctively.
