O Congress votes by two-thirds majority vote to propose an amendment

7. Which of the following is the part of the ratification process in the U.S. Constitution that has never been used?

O three-fourths of state legislatures ratify an amendment

O three-fourths of state conventions ratify an amendment

O Congress calls for a national constitutional convention

To determine the answer to this question, we need to understand the ratification process for amending the U.S. Constitution. According to Article V of the Constitution, there are two methods for proposing and ratifying amendments:

1. Proposal: An amendment can be proposed by a two-thirds majority vote in both houses of Congress or by a constitutional convention called by two-thirds of state legislatures.

2. Ratification: Once an amendment is proposed, it needs to be ratified by either three-fourths of state legislatures or three-fourths of state conventions.

Given this information, we can identify the part of the ratification process that has never been used by Congress, which is option:

O Congress calls for a national constitutional convention.
