Final answer:
To enable Justin to participate in the obstacle course, allowing him to bypass overly challenging obstacles and making thoughtful modifications is key to his inclusion and safety.
Step-by-step explanation:
To help Justin, who has limited range of motion in his legs, fully participate in the obstacle course, the best accommodation would be to allow him to go around obstacles that are too difficult. This approach provides him with the opportunity to be actively involved alongside his friends while also keeping safety and his physical capabilities in mind. Additionally, offering modifications to some obstacles or providing alternative tasks that match Justin's abilities can help include him in the competition in a meaningful way.
It's important for all participants to have a chance to compete and enjoy the spirit of the game, irrespective of their physical abilities. Therefore, it is essential to create an inclusive environment where Justin can feel like an integral part of the team and the fun. Special care should be taken to ensure that the course is set up in an open location with ample space, thus reducing the chances of tripping or falling, especially for those with limited mobility.
