What is one power that is denied to Congress?

One power that is denied to Congress is the authority to grant titles of nobility. This prohibition is rooted in the desire to prevent the establishment of an aristocracy and ensure a system of government based on equality and merit rather than heredity or social class. The framers of the Constitution wanted to create a republic where citizens had equal standing and opportunities, thus prohibiting Congress from conferring aristocratic titles or privileges that could undermine this principle.

The other options listed are powers that Congress does hold. Declaring war is a constitutional power granted to Congress, enabling it to authorize military action. Laying taxes is also an explicit power of Congress, allowing for the collection of revenue to fund government operations. Additionally, Congress has the authority to borrow money on credit, which is essential for managing federal finances and funding governmental initiatives. By distinguishing itself from systems that might create hierarchical structures like nobility, Congress's lack of power to grant titles reinforces the democratic foundation of the United States.
