What is one power of the federal government as defined by the Constitution?

The power to declare war is explicitly granted to the federal government by the U.S. Constitution, specifically in Article I, Section 8. This section outlines the powers of Congress, which includes the authority to declare war, raise and support armies, and maintain a navy. This power is essential as it recognizes the federal government's role in making significant decisions affecting national security and defense, responsibilities that are typically beyond the scope of state governments.

In contrast, the options related to providing schooling and education, issuing driver's licenses, and approving zoning and land use fall primarily under the jurisdiction of state and local governments. Each of these areas is governed by state laws and regulations, reflecting the principle of federalism in the United States, where certain powers and responsibilities are decentralized and managed by individual states rather than the federal government.
