Final answer:
The staff is located close to the cells mainly to provide better supervision of inmates, facilitate communication, and prevent escape attempts, with the overall goal of maintaining security and order.
Step-by-step explanation:
The purpose of locating the staff close to the cells is primarily to provide better supervision of the inmates. This setup enables staff to observe and monitor the behavior and activities of inmates, thereby maintaining control and ensuring the security of the institution.
Additionally, the proximity facilitates quicker communication between staff and inmates, which is essential for effective management and addressing the needs or issues that may arise. Moreover, the close presence of staff acts as a deterrent to prevent escape attempts, as inmates are aware that they are being watched closely. While ensuring the safety of the staff is also a consideration, the main goal is the overall security and order of the facility.
