Exercise can help build strong muscles to support places where two or more bones meet, which are called _____.

• A. Joints
• B. Kneecaps
• C. Eyes
• D. Ears

Answer: (A)

Strong muscles help stabilize joints—the places where two or more bones meet. When you exercise the muscles around a joint, they control movement better, absorb more impact, and keep the bones in proper alignment, which protects the joint from injury. The kneecap is a bone near the knee, not the meeting point of two bones; eyes and ears are sensory organs, not joints. So the term for where two or more bones meet is joints.
