Question

which phrase best completes the diagram? state powers create local governments federal powers collect taxes? a. control trade in states b. make treaties c. enforce laws d. oversee elections

Explanation:

The power to make treaties is a federal - exclusive power. The power to control trade in states can have both state and federal aspects but is more complex. The power to enforce laws can be shared in some respects but also varies by context. The power to oversee elections can also have state and federal elements. However, making treaties is a power that is clearly within the realm of federal powers and not a shared or state - only power.

Answer:

B. Make treaties
