Under concurrent powers, which function is shared by both federal and state governments?

• A. Issuing currency
• B. Declaring war
• C. Establish court systems
• D. Negotiating treaties

Answer: (C)

Concurrent powers are powers shared by both the federal and state governments, allowing each to exercise authority in certain areas within their own spheres. Establishing and maintaining a court system is a good example: both levels create and organize courts—state courts for state law matters and federal courts for federal questions—while they can fund and structure those systems within their jurisdiction. Other options belong to the national government: issuing currency is handled by the federal government; declaring war is a national prerogative; negotiating treaties is a federal responsibility in foreign affairs. Thus, establishing court systems is the shared function.
