Jack plays a lot of sports, but he has some difficulty reacting to what he sees and hears at the same time. which skill should he work on to overcome this challenge?

Coordination, reaction time, or hand-eye coordination.

The correct anwser is: Coordination.

Explanation:

Coordination can be defined as the ability to perform movements efficiently, accurately, quickly and in an orderly manner. That is, coordination is what allows us to move in a synchronized way all the muscles involved in an action to perform it in the most adapted way possible. Although motor skills and movement involve a large number of frontal brain areas, the main structure responsible for coordination is the cerebellum. Bad coordination can prevent us from living our daily lives normally. It is not uncommon for coordination to be one of the capacities that most deteriorates with aging, hindering the activities of daily living. Fortunately, coordination can be trained through cognitive stimulation.

because health skills are tools and strategies and also practical skills are also something you need to learn (like tools and strategies) and put it in reality.
