Which ability is described as the body's capacity to react when the body is no longer upright and steady?

• A. Stand up
• B. Sit down
• C. React
• D. Fall

Answer: (C)

The ability being tested is how quickly and effectively the body can respond to a loss of balance to regain an upright, steady position. Reacting encompasses the rapid motor adjustments the body makes to reestablish balance, using coordinated movements of the arms, legs, and torso to stop a fall. Standing up or sitting down are individual actions, not the overall capacity to respond to imbalance, and falling is the outcome when a response isn’t made. So, reacting best describes the body's capacity to respond to instability.
