Which motion listed is not debatable but may be amended?

The correct answer is that the motion to recess is not debatable but can be amended. In parliamentary procedure, certain motions are classified based on their characteristics related to debate and amendment.

The motion for recess is used to pause the meeting for a specific period. It is generally considered to be a procedural motion that does not require debate because it pertains to managing the meeting's flow rather than the content of an agenda item. However, members can propose amendments to specify the length of the recess or conditions under which the recess will take place. This flexibility allows the assembly to adapt the motion to fit the needs of the meeting while keeping the process efficient.

Understanding the nature of motions and their rules is crucial for effective participation in meetings and for ensuring that discussions remain focused on substantive issues. The other listed motions have different characteristics in terms of debate and amendment, making them distinct from the motion to recess.
