What fraction of states is required to call a National Convention to propose amendments?

• A. 2/3 of the states
• B. 3/4 of the states
• C. 1/2 of the states
• D. All states

Answer: (A)

The thing being tested is how a National Convention to propose amendments is triggered. According to Article V of the Constitution, two-thirds of the state legislatures must apply for such a convention. Today that means 34 of 50 states. This high threshold is meant to ensure broad agreement among states before reopening the Constitution. The other numbers describe different steps (like ratification by three-fourths of the states) and aren’t about calling a convention. So the correct answer is two-thirds of the states.
