Final answer:
Health care and educational support are two critical kinds of human services that families might need every year, providing necessary assistance for maintaining health and improving educational outcomes.
Step-by-step explanation:
One of the two kinds of human services that a family might need every year is health care. This includes preventive services like annual physical exams, vaccinations, and screenings, as well as treatment for illnesses or injuries. Another critical human service commonly required is educational support, which can come through programs like early childhood education, after-school tutoring, or financial aid for college students.
