Final answer:
Boards like the Federal Reserve were supposed to change members often to prevent corruption, but longer terms were established to protect them from political forces, creating stability in monetary policy.
Step-by-step explanation:
The question appears to concern the frequency of changes in the membership of a board, such as the Federal Reserve or a legislative body. Boards were supposed to change members often, but in practice, longer terms have insulated boards like the Federal Reserve from political forces, ensuring continuity and stability in policy decisions. Several revolutionary ideas from the American Revolution sought regular elections to prevent corruption and ensure representatives remained accountable to the communities they served. Nonetheless, mandates like the Federal Reserve's insulate it from short-term political pressures.
