What is a clear sign that a guest is attempting to stay afloat?

The indication of a guest attempting to stay afloat can be clearly recognized when their arms are extended out to the side with minimal movement. This position suggests that the individual is trying to maintain buoyancy by maximizing their body's surface area, which is a common strategy used by swimmers who find themselves struggling but are still capable of staying afloat.

When arms are extended, it often indicates that the person is in a state of effort, using their body to balance and remain on the surface rather than actively swimming or playing. This posture is particularly notable when movement is reduced, as it suggests they might be conserving energy while trying to stabilize themselves in the water.

Other options, such as having fun while swimming, kicking vigorously, or floating calmly on their back, do not necessarily convey that a person is struggling to stay afloat. Each of these activities can indicate a level of comfort and proficiency in the water, contrasting with the sign of distress or struggle that the question seeks to identify.
