Final answer:
The day-to-day headquarters responsibilities of a sorority typically fall to the national headquarters staff or the local sorority's executive board or officers.
Step-by-step explanation:
The execution of the sorority's day-to-day headquarters responsibilities typically belongs to the sorority's national headquarters staff or, if the sorority is small and less structured, its executive board or officers at the local level. These individuals are responsible for maintaining the organization's operations, including financial management, member services, event planning, and ensuring adherence to national policies and standards. For larger organizations, this could also involve full-time paid staff who manage the various aspects of the sorority's operations.
