Final answer:
The quoted section from the U.S. Constitution is referring to expressed powers related to taxation and commerce regulation as detailed in Article I, Section 8.
Step-by-step explanation:
The quoted section from the U.S. Constitution falls under expressed powers related to taxation and commerce regulation. The Constitution outlines these powers in Article I, Section 8, where it lists the enumerated powers of the legislature, including the authority to levy and collect taxes, and regulate commerce among the states and with foreign nations. Taxes are a critical tool for the government as they enable it to fund other powers, whether enumerated, implied, or inherent. Regulation of commerce has allowed the national government to claim other powers, such as prohibiting racial discrimination in transportation, which is linked to its commerce regulation abilities.
