What is one power that belongs only to the federal government?

• A. Regulating education
• B. Establishing post offices
• C. Conducting elections
• D. Providing welfare

Answer: (B)

The power to establish post offices belongs exclusively to the federal government, which is outlined in Article I, Section 8 of the U.S. Constitution. This section grants Congress the authority "to establish Post Offices and post Roads." The establishment and maintenance of a national postal system are critical for facilitating communication and commerce across the states, which cannot be efficiently managed at the state or local level. Unlike other powers that are shared between federal and state governments, such as regulating education or conducting elections, the establishment of post offices is singularly a federal responsibility, ensuring a consistent national infrastructure for postal services.
