What does the Constitution primarily do?

The Constitution primarily sets up and defines the government, establishing the framework through which the United States operates. It delineates the structure, powers, and responsibilities of the three branches of government: the legislative, the executive, and the judicial. By detailing how these branches interact and the limits of their powers, the Constitution ensures a system of checks and balances that prevents any one branch from becoming too powerful. This foundational document also establishes the Constitution as the supreme law of the land, influencing all laws and governance in the country.

While the other options touch on specific aspects of governance, they do not capture the overarching purpose of the Constitution. The responsibilities of the President are indeed outlined within the Constitution, but this is just a part of the larger framework. Similarly, individual state powers are defined within the Constitution, particularly through the Tenth Amendment, but the document as a whole is more about the establishment and organization of the federal government. Lastly, while the Constitution does include provisions regarding international treaties, it does not primarily focus on this area; rather, it is essential in providing the broader context of governance.
