Which statement best defines concurrent powers in a federal system?

• A. powers exercised by state or provincial governments that are denied to national governments
• B. powers that have been expressly defined in a national constitution
• C. powers not stated in a national constitution that nation-states have always exercised
• D. powers that can be exercised by state and provincial governments as well as national governments

Answer: (D)

Concurrent powers are authorities that both the national government and the state governments can exercise. This means lawmakers at both levels can create and enforce laws in the same policy areas, such as taxation, criminal law, and infrastructure. While both levels can act in these areas, federal law may prevail over state law when there’s a conflict due to the supremacy of national statutes. This sets concurrent powers apart from powers reserved exclusively for states or exclusively for the national government. For example, both the federal government and states can levy taxes, illustrating how shared authority works in a federal system.
