The writer wants one consistent line of reasoning across the passage. Main position A youth sports league is revising training for volunteer coaches. The league should require age-appropriate instruction in feedback, safety, and inclusion because technical knowledge alone does not ensure that young athletes learn in a supportive environment. Competition can remain part of the league as long as coaches know how to teach it safely and respectfully. Supporting paragraph [Volunteer coaches bring different levels of playing and teaching experience.] Training could show coaches how to correct a skill without humiliating a player. A safety module could explain when an athlete must stop activity and receive medical evaluation. Inclusion scenarios could help coaches adapt drills so beginners and experienced players remain engaged. Which revision best establishes that consistent line of reasoning without overstating the evidence or dropping the writer's qualification?
