What does the Constitution do?

The Constitution serves several critical functions that are fundamental to the governance of the United States. It establishes the framework for government, dictating how it is organized and how power and responsibilities are divided among different branches, such as the legislative, executive, and judicial branches. This setup is necessary for functioning democracy and provides clarity on the roles of each branch.

In addition to laying the groundwork for government operations, the Constitution defines governmental powers and limitations. It delineates what the government can and cannot do, helping to protect against the abuse of power. This definition is essential for maintaining a balance of power and ensuring that no single entity within the government becomes too powerful.

Furthermore, the Constitution includes provisions, particularly in the Bill of Rights, that safeguard the fundamental rights of individuals. These rights include freedoms such as speech, religion, and assembly, which are crucial for protecting citizens from government overreach.

Given that the Constitution not only sets up and defines the government but also protects the basic rights of Americans, it is comprehensive in its role, making "All of the above" the correct choice. Each aspect mentioned contributes to the overall purpose and significance of the Constitution in American society.
