What is one power held by the states?

The power to provide education is a responsibility that is primarily held by the states and is a reflection of the principles of federalism in the United States. The Constitution allows states to establish and maintain their own educational systems, which includes creating and operating public schools, determining educational standards, and managing funding for education. This decentralized approach enables states to tailor their education systems to meet the unique needs and preferences of their populations.

In contrast, the other options listed involve powers that are typically reserved for the federal government. Declaring war, regulating immigration, and conducting foreign affairs are all responsibilities assigned to the national government, underscoring its role in maintaining national security and international relations. By granting states the authority to provide education, the Constitution empowers them to address local needs more effectively.
