Which of the following is a requirement before a main motion is discussed?

A main motion requires a second before it can be discussed in a meeting. This requirement is crucial because it demonstrates that at least one other member supports the motion, indicating that the idea is worthy of discussion. The act of seconding a motion is a way to gauge interest and ensure that the assembly is willing to consider the proposal further. Without a second, the motion cannot proceed to debate or be put to a vote, which helps to maintain order and efficiency during meetings.

While some organizations may require motions to be written down to maintain clarity, this is not a universal requirement. Similarly, emailing a motion to all members or having it approved by the chair are not necessary steps for a motion to be discussed. The requirement for a second is a fundamental democratic principle in parliamentary procedure, allowing for collaborative decision-making within a group.
