A more thorough explanation:

A chairperson is the person who leads a meeting or organization. They are responsible for making sure the meeting runs smoothly and everyone follows the rules. The chairperson can be called by different names depending on the situation, such as chairman, chairwoman, or chairperson.

• During the meeting, the chairperson called for order when people started talking over each other.
• The treasurer reports directly to the chairperson, who is the head of the organization.
• When the regular presiding officer was absent, the chairperson pro tempore was elected to lead the meeting.

These examples show how the chairperson is responsible for leading the meeting and making sure everyone follows the rules. They also show how the chairperson can be appointed or elected depending on the situation.
