Which of the following does NOT qualify as an institution?

An institution is typically defined as a significant entity organized for a specific purpose, which often encompasses established norms, practices, and expectations within a society. Colleges, hospitals, and prisons serve essential societal functions and possess structured environments that provide essential services or governance.

A college provides education and training, contributing to skill development and knowledge dissemination. A hospital offers healthcare services and is vital for public health and wellbeing. A prison is a correctional facility that administers justice and rehabilitation for offenders, playing a critical role in maintaining societal order.

In contrast, a swimming pool does not function as an institution in the same way these other entities do. While it can be a place for recreation and leisure and might serve a community in that way, it lacks the formal structure, purpose, and societal role typically associated with institutions. Thus, a swimming pool does not carry the same implications of organized authority, guidelines, and large-scale societal impact that characterize institutions like colleges, hospitals, and prisons.
