Final answer:
The process depicted is intended to permit updates to the Constitution in a manner that requires broad consensus, making it deliberately rigorous to ensure that any changes reflect a strong, collective agreement nationwide.
Step-by-step explanation:
The process illustrated in the diagram is designed to allow the Constitution to be updated to suit changing times (D). Amending the Constitution is a complex process that was intentionally designed to require broad consensus across both the federal and state levels. The requirement for two-thirds supermajority of both chambers of Congress to propose an amendment, and a three-fourths supermajority of state legislatures to ratify it, ensures that amendments reflect widespread agreement. This high threshold helps prevent small political factions from easily altering the fundamental law of the land, thereby creating stability and continuity in the government's guiding document.
