Step-by-step explanation:
States have reserved powers because the United States Constitution reserves certain powers for the federal government and leaves the rest for the states to decide. This is known as the principle of federalism. The reserved powers of the states allow them to retain their autonomy and independence from the federal government, which helps to ensure that a strong system of checks and balances is maintained. This helps to ensure that the federal government is not too powerful and that states have the ability to make their own decisions without interference. States have their own constitutions and laws that govern their internal affairs, and they can choose to pass legislation that is not in line with federal law. This allows states to make decisions and laws that are specific to their needs and interests. These reserved powers are essential for ensuring that the federal government does not become too powerful and that states can remain autonomous.
