Which officer must be able to gain the confidence of others, since he or she may be called on to settle controversial issues?

The correct choice indicates that the Parliamentarian is the officer expected to gain the confidence of others, particularly in contexts where they may need to mediate or settle disputes. This role is vital in any organization, especially during meetings or discussions where decisions require adherence to established rules and procedures.

The Parliamentarian’s main responsibility is to ensure that meetings are conducted fairly and in accordance with parliamentary procedure. This often involves clarifying rules, providing guidance on motions, and interpreting the bylaws, all of which can involve handling politically sensitive or controversial issues. Gaining the confidence of members is essential because stakeholders need to trust that the Parliamentarian will apply rules impartially and effectively, thereby facilitating productive dialogue and resolution among conflicting viewpoints.

The other roles, such as Secretary, President, and Treasurer, have specific functions that do not primarily revolve around mediator responsibilities. The Secretary manages documentation, the Treasurer handles financial aspects, and the President leads the discussion. While all these positions are important and require a certain level of trust and respect, the unique nature of the Parliamentarian's role in resolving disputes makes them particularly crucial in this context.
