What is typically required before a motion can be debated?

Before a motion can be debated, it is typically required that the motion receives a second. This process ensures that at least one other member of the assembly agrees that the motion is worthy of consideration. By requiring a second, the parliamentary procedure maintains order and efficiency in discussions, preventing time from being wasted on motions that have no support among other members. The act of seconding a motion indicates that there is interest in discussing the motion further and allows the chair to put the motion before the assembly for debate. This promotes a structured decision-making process within the group.

The other options do not accurately describe the standard procedure before a motion can be debated. For example, unanimous consent is not required for all motions, and written proposals or prior discussions may be helpful but are not prerequisites for debating a motion.
