Which of the following occurs when a horse evades or passes a fence?

When a horse evades or passes a fence, it is referred to as a run-out. This action occurs when the horse chooses not to jump over the obstacle and instead moves sideways or away from it. Run-outs can be a result of various factors, including the horse's level of training, confidence, or the rider's handling of the situation.

Understanding this behavior is crucial for both training and competition, as it highlights the importance of establishing trust and clear communication between the horse and rider. In contrast, a refusal indicates that the horse has not attempted the jump at all; a knockdown involves the horse knocking a rail off the jump; and a break of gait refers to a change in the horse's pace or rhythm, none of which are specifically associated with evading a fence like a run-out is.
