What is one of the main functions of state governments?

One of the primary functions of state governments is to establish local school systems. This responsibility is rooted in the U.S. Constitution, which grants states the authority to regulate education within their borders. State governments play a crucial role in managing public education by creating and funding school districts, setting educational standards, and ensuring access to quality education for all students. This function is essential for promoting civic education and preparing future citizens to participate in democracy.

In contrast, the other choices relate to functions typically reserved for the federal government. For example, declaring war and negotiating peace treaties are responsibilities that fall under the purview of the national government, as they pertain to foreign relations and national defense. Taxing federally also refers to the federal government's capacity to impose and collect taxes, which is separate from state taxation authority. Thus, establishing local schools distinctly highlights the vital role states play in the educational framework of their communities.
