The body's ability to perform the same task repeatedly over time is best described by which term?

• A. Culture
• B. Endurance
• C. Social Support
• D. Legal

Answer: (B)

Endurance is the body's ability to perform the same task repeatedly over time. It covers both muscular endurance, the capacity of your muscles to keep contracting over many repetitions, and cardiovascular endurance, the ability of your heart and lungs to sustain that activity without fatiguing too quickly. When you repeat a task, your energy systems work to supply more fuel, remove byproducts, and you push through fatigue, so training specifically builds stamina and efficiency to maintain the effort for longer periods. That’s why endurance best describes the scenario. The other terms don’t fit because culture refers to shared beliefs and customs, social support means help you receive from others, and legal deals with laws and rules—none of these describe sustained performance over time.
