The diagram represents a continuum from closed to open skills - HSC - SSCE Personal Development and Physical Education - Question 18 - 2003 - Paper 1

To determine which group of skills fits on the continuum from closed to open skills, we must first understand the characteristics of closed and open skills:

• Closed skills are performed in a stable environment where the performer knows exactly what to do and when to do it (e.g., gymnastics floor routine).
• Open skills require adaptability and are performed in unpredictable environments (e.g., riding a wave on a surfboard).

Now, let's evaluate the options:

• (A) Gymnastics floor routine (closed), high jump (closed), defend an attacking move in hockey (open): This has a mix of closed and open skills.
• (B) Long jump (closed), dive from a 3-metre springboard (closed), free throw in basketball (closed): This consists only of closed skills.
• (C) Rebound in netball (open), return of serve in tennis (open), ride a wave on a surfboard (open): These are all open skills, indicating a high degree of unpredictability.
• (D) Softball pitch (closed), target shooting in archery (closed), goal shooting in soccer (open): This option includes a mix of closed and open skills.

Therefore, the most appropriate representation of the continuum from closed to open skills is option C.
