Question

select the best evidence to support the statement that playing sports is a major cause of injury in young people. more than 38 million children and adolescents participate in organized sports in the united states each year. still more participate in informal recreational activities. although sports participation provides numerous physical and social benefits, it also has a downside: the risk of sports - related injuries. these injuries are the most common cause of musculoskeletal injuries in children treated in emergency departments and injury - related primary care office visits. although sports injuries can range from scrapes and bruises to serious brain and spinal cord injuries, most fall somewhere between the two extremes. an ankle sprain is the most common athletic injury. adapted from national institute of arthritis and musculoskeletal and skin diseases, \preventing musculoskeletal sports injuries in youth: a guide for parents\

Explanation:

To support the statement that playing sports is a major cause of injury in young people, we need evidence showing sports - related injuries are prominent among young people's injuries. The sentence "These injuries are the most common cause of musculoskeletal injuries in children treated in emergency departments and injury - related primary care office visits" directly links sports - related injuries (implied by "these injuries" referring to sports - related injuries from the context) to being the most common musculoskeletal injuries in children's medical visits for injuries, thus strongly supporting the claim. Other parts either talk about participation numbers or the range of sports injuries, not the major cause aspect as directly as this sentence.

Answer:

These injuries are the most common cause of musculoskeletal injuries in children treated in emergency departments and injury - related primary care office visits.
