Which of the following would be considered an activity limitation caused by a disability?

The identification of difficulty in walking or moving freely as an activity limitation caused by a disability is grounded in the definition of what constitutes an activity limitation. Activity limitations are restrictions in an individual's ability to perform tasks or actions, and in this case, the difficulty in walking clearly exemplifies a physical limitation on mobility.

This could affect daily routines, social interactions, and overall independence, illustrating how such a difficulty can significantly impact an individual's quality of life and ability to engage fully in various environments. Recognizing these limitations is crucial in providing appropriate supports and accommodations to foster an inclusive environment.

In contrast, the other options do not reflect limitations. Participating in sports, performing well academically, and being fluent in a language indicate abilities and strengths rather than limitations. Therefore, they do not align with the definition of an activity limitation related to a disability.
