Which of the following is a debatable subsidiary motion?

• A. Postpone Definitely
• B. Refer to a Committee
• C. Amend
• D. Postpone Indefinitely

Answer: (D)

The key idea here is whether a subsidiary motion is open to argument about the merits of the main motion or is treated as a procedural step. The motion to postpone indefinitely stands out because it directly affects whether the main motion will ever be considered again. Debating this motion is essentially debating the fate of the proposal itself: should we keep discussing it at all, or kill it now by postponing indefinitely? That kind of substantive discussion about the continued consideration of the issue is what makes it debatable.

In contrast, the other options involve procedural handling or timing rather than a direct judgment about the main motion’s merits. Postponing to a definite time is about when to consider the motion, not whether it should be considered at all; referring to a committee delegates study to others and is a procedural step; and amending changes the wording or details of the main motion, which is a different avenue of debate focused on the motion’s language. Since the question asks which is debatable, the motion that invites debate about continuing vs. stopping consideration is the one to Postpone Indefinitely.
