Explanation:

Question 5

Stretching exercises are known to increase the range of motion of joints, which is flexibility. Speed, endurance, and coordination are improved by other types of exercises (e.g., sprinting for speed, cardio for endurance, balance drills for coordination).

Jumping rope is a cardiovascular exercise that increases heart and lung capacity, thus improving cardiovascular endurance. It doesn't primarily build muscular strength (A), balance (B is more for stability exercises), or body composition (which involves fat - muscle ratio changes from diet and overall exercise, not just jumping rope).

Heart rate is the number of heartbeats per minute. To measure it, you can feel the pulse (beats) at the wrist (radial pulse) or neck (carotid pulse) and count. Counting breaths (A) measures respiratory rate, a thermometer (B) measures temperature, and asking a friend (D) is not a valid measurement method.

Answer:

C) Flexibility
