Which concept describes the division and sharing of power between national and state governments?

• A. Checks and Balances
• B. Republicanism
• C. Federalism
• D. Separation of Powers

Answer: (C)

Power division between national and state governments is described by federalism. Federalism means authority is shared between two levels of government, each deriving its power from the people and defined by the Constitution. The national government handles areas like defense, currency, and regulating interstate trade, while states handle local matters such as education and local public laws. Some powers are shared, or concurrent, such as taxation, with both levels active in those areas. The Supremacy Clause ensures national laws win in conflicts, but states keep certain reserved powers of their own. This idea differs from checks and balances, which focuses on how branches within the national government limit each other; republicanism, which centers on how people elect representatives; and separation of powers, which describes the split of government into branches rather than levels. For example, a federal system allows the national government to set nationwide rules on interstate commerce while states tailor education policies to their communities.
