Question

which source would best support an argumentative essay on the importance of protective gear for those playing sports?
○ an editorial on the need for a community sports complex
○ an interview with a professional golfer
○ a case study of sports - related injuries
○ a medical journal on the causes of tennis elbow

Explanation:

To support an argument about the importance of protective gear in sports, we need a source that shows the consequences of not using it. An editorial about a sports complex (first option) is irrelevant. An interview with a professional golfer (second option) may not focus on injury prevention via protective gear. A medical journal on tennis elbow (fourth option) is too narrow as it only focuses on one specific injury. A case study of sports - related injuries (third option) can show the types and prevalence of injuries in sports, which can be used to argue that protective gear is important to prevent such injuries.

Answer:

a case study of sports - related injuries
