Which is a power that belongs only to the federal government?

Regulating interstate commerce is a power that is specifically designated to the federal government by the U.S. Constitution. This authority allows the federal government to manage trade and commerce that crosses state lines, ensuring a cohesive and uniform economic framework across the nation. This power is important for maintaining a stable economy and preventing individual states from enacting conflicting trade laws that could disrupt interstate trade.

In contrast, establishing local governments, conducting elections, and providing education are powers typically reserved for state and local authorities. States have the responsibility to set up their own governmental structures and manage election processes, as well as to oversee public education systems. These responsibilities allow states to tailor their governance and policies to the specific needs of their populations.
