Question

which is the most effective piece of evidence to support the claim that adolescents who exercise daily are healthier than those who are inactive? spending too much time on the couch watching television can have negative consequences for adolescents. adolescents who exercise daily have stronger muscles, higher levels of respiratory fitness, and lower levels of body fat. there are three categories of exercise that adolescents should partake in: aerobic, muscle - strengthening, and bone - strengthening. adolescents enjoy different types of activities, such as dance, martial arts, or team sports.

Explanation:

The claim is about the health - benefits of daily exercise for adolescents compared to inactivity. The second option directly lists health - related advantages (stronger muscles, higher respiratory fitness, lower body fat) of adolescents who exercise daily, making it the most relevant evidence. The first option only mentions the negative of being inactive, the third option is about types of exercises not health benefits, and the fourth option is about adolescent preferences in activities.

Answer:

Adolescents who exercise daily have stronger muscles, higher levels of respiratory fitness, and lower levels of body fat.
