Which motion permits the postponement of a main motion?

The motion that permits the postponement of a main motion is the motion to "Table." When a motion is tabled, it means that the discussion on that motion is suspended, allowing members to focus on other business. This is often used to delay consideration of an issue that may need more information or time to appropriately address.

Tabling is designed to take the main motion off the floor temporarily but does not result in a definitive decision on the matter. Instead, it allows the assembly to return to that motion later, assuming no other motions or business take precedence, and provided the motion has not been tabled indefinitely.

In contrast, the other options serve different purposes; for instance, "Reconsider" allows a motion that has already been decided upon to be revisited, while "Previous Question" calls for an immediate vote on the current matter, thus accelerating rather than delaying decisions. "Close Nominations" is specific to halting further nominations for a position, which doesn't pertain to the postponement of motions.
