What is the parliamentary term for a motion that secures an immediate vote, thus ending debate?

The correct answer is Previous Question, which refers to a motion in parliamentary procedure designed to end debate on a topic and move directly to a vote. This motion can be utilized when members feel that enough discussion has occurred and that it's time to make a decision. By invoking this motion, the assembly can avoid prolonging the discussion further, allowing for efficiency in decision-making.

The other options, while relevant to parliamentary procedure, serve different purposes. A Point of Order is a request for clarification on the rules or procedures being followed. A Table Motion is used to temporarily set aside a motion or matter, essentially delaying its discussion. An Amend Motion is intended to make changes to a pending motion, not to conclude debate. Therefore, Previous Question is the correct term for a motion aimed specifically at ending debate and securing an immediate vote.
