Which of the following is NOT included in a school building?

The correct choice indicates that outdoor facilities for athletic training are not typically included as part of the school building itself. School buildings generally refer to the physical structures that house educational activities and administrative functions, such as classrooms, gyms, and areas specifically designed for learning and immediate school operations.

Athletic training facilities, while they may be utilized by the school for sports and physical education, are often seen as ancillary to the primary educational purpose of the school building. They may exist on school property, but they are not classified as part of the school building in the context of educational use and infrastructure.

In contrast, gymnasiums and structures suitable for classroom use are integral components of a school, providing vital spaces for education and student activities. Additionally, maintenance or storage facilities, although not centrally located in terms of educational activities, are essential to the overall operation and maintenance of the school and can be considered part of the school's infrastructure.
