Which of the following is considered an "implied power" of the government?

The power to participate in space exploration is considered an "implied power" of the government because it is not explicitly stated in the Constitution but can be derived from the powers that are granted to the federal government. The U.S. Constitution gives Congress the authority to regulate commerce, promote the general welfare, and make laws necessary and proper for carrying out its duties. The pursuit of space exploration aligns with these powers, as it involves aspects of commerce, defense, and scientific advancement, which can be deemed necessary for the welfare of the nation and its interests.

Implied powers allow the government to adapt to new challenges and opportunities that were not foreseen by the framers of the Constitution. Space exploration falls into this category as it was not addressed at the time of the Constitution's drafting but has become a significant area of federal interest and activity.

The other choices reflect powers that are typically considered explicit or reserved powers. The regulation of marriage and divorce, the establishment of local governments, and the issuance of professional licenses are powers usually assigned to state governments, reflecting their primary role in regulating affairs within their jurisdiction. This distinction is essential in understanding the layers of power and the federal structure of government.
