Question

why does hosa require students join through a local chapter instead of joining as individuals?
hosa activities are so closely connected with the school curriculum.
hosa membership would be too expensive for individuals to afford.
all hosa activities are structured as team competitions.
hosa members must take frequent tests.

Explanation:

HOSA (Health Occupations Students of America) focuses on health - related career development. Its activities are closely tied to school curricula (like health science education in schools). The option about membership cost is not a core reason for chapter - based joining. Also, not all HOSA activities are team - only, and test - taking frequency isn't related to chapter - based joining. So the correct reason is that HOSA activities are closely connected with the school curriculum.

Answer:

A. HOSA activities are so closely connected with the school curriculum.
