Final answer:
Issuing licenses is an example of a reserved power, which are powers not delegated to the national government by the Constitution and thus are retained by state governments to regulate areas like professional licensing, education, and local governance.
Step-by-step explanation:
An example of a reserved power is issuing licenses. Reserved powers refer to those powers which are not enumerated or delegated to the national government by the Constitution and are therefore retained by the states. These powers allow state governments to effectively regulate the day-to-day lives of their citizens. For instance, while both state and federal governments have the power to collect taxes as a concurrent power, only states have the authority to issue licenses for driving, practicing law or medicine, and for other professional activities. This falls under their reserved power to regulate the health, safety, and general welfare of their citizens.
Other examples of reserved powers include regulating intrastate trade, establishing public schools, conducting elections, and establishing local governments. These powers are all essential for states to maintain autonomy and address the specific needs of their populations, separate from the responsibilities of the federal government.
