Explanation:

Question 11

• "Increasing socialization opportunities" is a social benefit, not physical.
• "Maintaining balance and flexibility" is a key physical benefit for older adults as regular activity helps preserve mobility and reduce fall risks.
• "Improving confidence and self - esteem" is a psychological benefit.
• "Accomplishing a weight - lifting goal" is too specific and not the best general physical benefit for older adults.

• "Require daily strenuous exercise" is not helpful as it may be too intense for many and not address barriers.
• "Address challenges like pain or fatigue with low - impact activities" is a valid way as low - impact activities can make exercise more accessible for those with pain or fatigue.
• "Limit on - site activity options to reduce confusion" would not help overcome barriers as it reduces choices.
• "Avoid educating people on the benefits of physical activity" is counterproductive as education can motivate people to be active.

• "Decreases oxygen levels in the blood" is incorrect as physical activity increases oxygen delivery.
• "Increases blood pressure" is incorrect as regular physical activity can help manage blood pressure.
• "Improving cardiovascular efficiency" is correct as physical activity makes the heart and blood vessels work more efficiently, improving circulation and heart function.
• "Reduces heart rate variability" is incorrect; physical activity can have positive effects on heart rate variability in a different way, but improving cardiovascular efficiency is a more direct benefit for cardiovascular health.

B. Maintaining balance and flexibility
