A diver performs a front one-and-a-half somersault from a platform ten metres above the pool - HSC - SSCE Personal Development and Physical Education - Question 14 - 2004 - Paper 1

To determine the correct description of the diving skill, we first need to understand the characteristics of the actions involved.

A front one-and-a-half somersault is a specific movement that includes a clear beginning and end, thus making it a discrete skill. Discrete skills are those that have a defined start and finish. In this case, the diver initiates the dive and concludes it upon entering the water.

Next, we need to analyze whether this skill is considered open or closed. An open skill is one that is performed in a changing environment, where the performer has to adapt to different conditions. A closed skill, on the other hand, is performed in a stable environment with little variation.

Given that a diving performance primarily takes place from a fixed platform to a pool, and the movements are predetermined and consistent, this can be categorized as a closed skill. The environment does not change during the action of the dive.

Based on this analysis, the best description for a diver performing a front one-and-a-half somersault would be: 'Discrete and closed'.
