Which of the following is an example of a subsidiary motion?

A subsidiary motion is used to assist the main motion and determine how it should be handled. The choice that is identified as the correct answer involves "postpone to a definite time," which allows members to set a specific time to address the main motion later. This ensures that the assembly can manage its agenda effectively and allows more pressing matters to be addressed immediately while deferring less urgent issues.

This type of motion is typical in parliamentary procedure as it helps maintain the flow of discussion and prioritize important issues, giving the assembly time to think about the motion or gather further information if needed.

The other options do not fit the definition of a subsidiary motion as closely. For instance, withdrawing or modifying a motion is often considered a way of revising the motion rather than a subsidiary motion that changes how the main motion is dealt with. A point of order addresses the correctness of procedures and isn’t aimed at changing the main motion, while division of the question pertains to separating a motion into distinct parts for independent consideration rather than postponing its discussion.
