Chronic fatigue may be evidenced by a learner's apparent?

Chronic fatigue can indeed manifest in various ways, but in the context of the choices provided, the most relevant indicator relates to a learner's apparent acceptance of unwarranted risks. When someone is experiencing chronic fatigue, their cognitive functions, decision-making abilities, and risk assessment may be impaired. This can lead to a diminished ability to recognize potential dangers or adverse outcomes, resulting in an increased propensity to engage in risky behaviors without fully grasping their consequences.

In learning environments, this could translate to a learner taking on challenges or activities without adequate consideration of their readiness or the demands of the task, which can be detrimental to both their health and educational success. Thus, the acceptance of unwarranted risks is a key behavioral change that can signal underlying chronic fatigue, making it the most relevant choice among the options provided.
