Which organization is NOT a part of the precursor to the IPC?

The World Health Organization (WHO) is not a part of the precursor to the International Paralympic Committee (IPC). The IPC was established to promote and facilitate sporting activities for athletes with disabilities, and its predecessor organizations specifically focused on sports initiatives rather than health.

In contrast, the other organizations listed were directly involved in the development and promotion of competitive sports for individuals with disabilities. The International Blind Sport Federation (IBSF) represents athletes with visual impairments, the CP International Sport Recreation Association (CPISRA) focuses on athletes with cerebral palsy, and the International Stoke Mandeville Games Federation (ISMGF) was directly involved in the organization of the Stoke Mandeville Games, which were foundational to the evolution of the IPC. Thus, the WHO's broader health-related objectives do not align with the specific sports-oriented mission of the precursor organizations to the IPC.
