If the chair knows that a majority of the assembly approves a motion, what can happen?

The correct choice highlights a procedural point regarding the chair's role in guiding a meeting. When the chair is confident that a majority of the assembly approves a motion, they have the authority to state the question without requiring a second. This is grounded in the understanding that if the chair knows a motion has majority support, it is unnecessary to spend time on a second, which traditionally serves to confirm that more than one member believes the motion is worth considering.

The other options do not accurately reflect parliamentary procedure. While a motion may seem to be quite supported, it still requires formal acknowledgment in the assembly. A motion being automatically accepted without a vote ignores the necessity of member participation and assent, which is essential to democratic decision-making. The requirement for a vote ensures that all members, regardless of the chair's assumptions, have the opportunity to express their views. Lastly, introducing a new motion when a majority exists would not be efficient or necessary, as it does not respect the existing motion that is already favored by the assembly.
