Final answer:
The first three articles of the U.S. Constitution define the structure and powers of the federal government's three branches, which differs from the subsequent articles that deal with federalism, the amendment process, and legal hierarchy.
Step-by-step explanation:
The first three articles of the United States Constitution differ from those that follow because they outline the structure and powers of the federal government. Specifically, Article I establishes the Legislative Branch (Congress), Article II outlines the Executive Branch (the presidency), and Article III sets up the Judicial Branch (the federal courts). Subsequent articles describe the American system of federalism, the amendment process, the supremacy clause, and the ratification process.
Notably, the first three articles provide the framework for the separation of powers and the system of checks and balances among the three branches of government. They dive into the specifics of how the legislative process works, the powers vested in the presidency, and the scope of judicial authority. Contrastively, the later articles focus on the relationship between states, the federal government, and the amendment process, rather than on individual rights or detailed governmental functionalities.
