Answer:
Central and state governments influence each other in a federal system of government.
Step-by-step explanation:
In a federal system of government the power is shared between the national or central government and the state and local governments. Under federalism, each level of government has sovereignty in some areas and shares power in others. This form of government differs from a unitary system, for example, as in the unitary system of government power relies only within the central government, and it is not shared with local or state governments.
