You shouldn't neglect physical activity because which statement is true?

• A. It improves complexion
• B. Exercise and recreation stimulate clear thinking
• C. It increases nails strength
• D. It reduces weight

Answer: (B)

Regular physical activity boosts brain function by increasing blood flow and oxygen to the brain, and by releasing chemicals that improve mood and reduce stress. This combination supports clearer thinking, better concentration, and improved decision-making, which is why exercising and engaging in recreation are the strongest reason not to neglect activity. Other potential benefits like a better complexion or stronger nails can occur, and weight reduction can happen, but these are less direct and depend on other factors such as diet and overall energy balance.
