What can be inferred about amendments to the Constitution?

Amendments to the Constitution indeed require a supermajority to be passed, which is a significant aspect of the amendment process. Specifically, an amendment can be proposed either by a two-thirds vote in both the House of Representatives and the Senate or by a constitutional convention called for by two-thirds of the state legislatures. This high threshold ensures that only changes with widespread consensus are likely to become part of the Constitution, highlighting the importance and stability of the foundational legal document.

While it is true that amendments are unique and not made frequently, the requirement for a supermajority is what really underscores the need for significant agreement among representatives and states. The other options suggest restrictions that do not align with the actual framework of the amendment process, as amendments are not limited to presidential introduction and their significance varies, but their potential to alter the Constitution is heavily contingent upon broad, bipartisan support.
