Answer:
The answer is "Federalism "
Step-by-step explanation:
The wording of this question represents the federalism principle. Its constitutional notion of federalism states that the US is an eternal union of individual countries, that it only grants the federal central government some specified responsibilities willingly.
The Constitution says that only those powers mentioned in the constitution are conferred to the administration. These are all the powers each region has presented to the national govt.
The nations are left with everything. One of the things that states are left with is to govern school systems.
