Which event is most likely to be organized by HOSA?

The event that is most likely to be organized by HOSA is a health careers competition. HOSA, which stands for Health Occupations Students of America, focuses on promoting career opportunities in the healthcare industry and enhancing the delivery of quality health care to the general public. Organizing competitions centered around health careers aligns with HOSA's mission and goals, as these events enable students to apply their knowledge, showcase their skills, and gain valuable experience relevant to their future careers in healthcare.

In contrast, the other options do not directly relate to HOSA's core focus. A dance competition and a school talent show emphasize entertainment and artistic performance rather than education and skills in the health sector. A fitness challenge, while related to health, does not specifically address the professional and educational aspects of health careers that HOSA promotes. Thus, the health careers competition stands out as the event that embodies HOSA's purpose and objectives.
