Final answer:
State governments are mandated to let citizens elect their representatives, which is vital for the functioning of a representative democracy in the United States.
Step-by-step explanation:
State governments are required to c. allow citizens to choose representatives. This requirement is a fundamental aspect of the democratic process in the United States, where people elect representatives to various levels of government including city councils, state legislatures, and Congress. These elected bodies are responsible for making laws, raising money through taxes, and allocating funds for various services.
It is important to note that states have concurrent powers shared with the national government, such as the right to collect income tax and provide for the welfare of the country. The federal taxes that are collected must be the same in every state, and states are treated as equals by the national government. Also, the national government cannot tax people of one state more than another.
