Define "shepherding" in a lifeguard context.

In a lifeguard context, "shepherding" refers to the practice of guiding swimmers to ensure they remain safe while enjoying the water. This involves closely monitoring their activities and positioning, providing support, and making sure that swimmers do not stray into dangerous areas, whether that be too deep water or sections of the pool that may pose a risk. This proactive engagement not only helps in preventing accidents but also creates a secure and positive swimming environment.

The emphasis in the correct answer is on the active role of the lifeguard in maintaining safety through guidance. By spending time with the swimmers and monitoring their behavior, a lifeguard can quickly respond to any potential issues or hazards. This contrasts with other choices which either suggest minimal interaction or focus on potentially encouraging unsafe practices, such as swimming faster or supervising from a distance without direct oversight.
