pregunta 23

Explanation:

• For the first question: Carlos can't touch his feet when bending, which is related to flexibility. Aerobic fitness (walking a mile, heart rate) and muscle strength (sit - ups) seem okay. Body composition is about the proportion of fat, muscle, etc., not directly shown here.
• For the second question: Competition can drive motivation (wanting to win), develop leadership (leading a team in a competition), and cooperation (working with teammates in some competitive team sports).
• For the third question: Staying physically fit is known to reduce the risk of chronic diseases like heart disease, diabetes (related to Natural Science - Medicine and Health).
• For the fourth question: Developed flexibility is important for good athletic performance as it helps in better movement, reducing injury risk (related to Natural Science - Sports Science which can be under Others in Natural Science).
