Final answer:
False, Nonprofit board members are responsible for governance and oversight, but they do not typically perform day-to-day supervision of volunteers, which is handled by staff or volunteer coordinators.
Step-by-step explanation:
The statement that one of the responsibilities of a nonprofit board member is to supervise volunteers is false. Nonprofit board members have a range of duties including governance, oversight of the organization's direction and strategy, financial management, and ensuring that the nonprofit adheres to legal and ethical standards. While board members do play a crucial role in overseeing and making key decisions for the nonprofit, the day-to-day supervision of volunteers is typically the responsibility of the organization's staff or volunteer coordinators.
