Health Knowledge and Injury Prevention

Correct answer: A. Injury prevention and treatment

Explanation: Sports medicine applies medical and scientific knowledge to the health, safety, performance, and recovery of physically active people. A major part of it is preventing injuries through suitable conditioning, warm-up, technique, equipment, and safety practices. When an injury occurs, sports medicine also involves assessment, immediate care, treatment, rehabilitation, and a safe return to activity. Option A is correct because injury prevention and treatment are central functions of this field. The other options are unrelated school or cultural activities: music, examination fees, and drawing do not define sports medicine or explain its role in physical education.

Correct answer: A. It helped prevent injuries and diseases

Explanation: The governing concept is health knowledge and injury prevention. When students understand warm-up, hydration, hygiene, correct technique, rest, nutrition, and warning signs of illness or injury, they can participate more safely and make responsible decisions. This knowledge helps reduce preventable injuries and lowers exposure to some health problems, so option A is correct. Option B is incorrect because health education encourages safe participation rather than abandoning sport. Option C is unrelated: better knowledge does not remove the need for suitable playgrounds. Option D is also false because health awareness can support cooperation and team participation instead of reducing teamwork.
