What is one power of the federal government under our Constitution?

The power to print money is an essential authority granted to the federal government under the Constitution, specifically through the establishment of the U.S. Mint and the Federal Reserve System. This power is crucial for maintaining a stable currency and facilitating economic growth. The Constitution empowers Congress to "coin money" and regulate the value thereof, which underscores the federal government's role in managing the nation’s monetary policy.

In contrast, the other choices relate to powers that do not fall under federal jurisdiction. The authority to collect taxes is indeed a power of the federal government, but it is not exclusive to it, as state governments have this power as well. The regulation of intrastate commerce is primarily a state power, while the establishment of schools is also traditionally under state control. Therefore, the ability to print money stands out as a distinctly federal power that plays a fundamental role in the governance and financial structure of the country.
