Which of these duties is not the responsibility of the President?

The responsibility of maintaining member attendance and activity records typically falls under the role of the chapter secretary, not the president. The president's primary duties focus on leading meetings, setting agendas, guiding discussions, and representing the chapter at various events. Conducting meetings involves not just managing the logistics but also facilitating discussions and ensuring that the meeting progresses smoothly. Appointing committees is equally important, as this helps delegate tasks and engages members in various projects, enhancing the chapter's effectiveness. Therefore, the correct choice highlights a duty that is generally outside the president's realm of responsibilities.
