What must occur before direct consideration of the main motion can continue?

Before the direct consideration of the main motion can proceed, a secondary motion must be acted upon. This is crucial because secondary motions are designed to address specific issues or matters that arise during the discussion of the main motion. They can include motions to amend, table, or refer the main motion to a committee.

The rationale behind this requirement is to ensure that any necessary adjustments or procedural actions related to the main motion are completed first. This allows the assembly to focus on the main motion with the understanding that all related concerns have been adequately addressed. Without this step, the deliberation could become chaotic or unfocused, as the body might want to resolve ancillary matters that impact the main motion before moving forward.

The other options involve procedural aspects that are not prerequisites for the main motion's consideration. Resolving questions of privilege, for example, can take place but is not a requirement before discussing the main motion. Therefore, acting upon a secondary motion stands out as the necessary condition to ensure a smooth and orderly discussion of the main proposal.
