When can a "Division of the House" be called?

A "Division of the House" can be called when the results of a vote are unclear. This occurs when there is a visible disagreement among members regarding the outcome of a voice vote, where the presiding officer may be unable to determine which side has more support. In such instances, a Division of the House allows members to stand up to indicate their vote more definitively, thus providing a clearer tally of support for or against a motion. This procedure ensures transparency and accuracy in the decision-making process of the assembly, allowing for proper recording of the votes cast.

The other options pertain to different procedural aspects within parliamentary procedure. For example, debates on motions and proposals for new motions involve front-end discussion and deliberation rather than definitive ways to clarify voting results. Similarly, adjourning a meeting requires a different set of motions and discussions, not a Division of the House. Therefore, the option that aligns with the concept of clarifying an unclear vote is indeed the correct one.
