Explain the following statements:
$(a)$ Being disease-free is not the same as being healthy.
$(b)$ Community health is essential for good individual health.
$(c)$ Villagers suffer from cholera more than urban people.

(N/A) Health refers to a state of complete physical,mental,and social well-being,not merely the absence of disease. $A$ person may be disease-free but still suffer from poor mental or social health.
$(b)$ Individual health is dependent on the environment. Community health ensures proper sanitation,hygiene,and disease control,which prevents the spread of infectious diseases to individuals.
$(c)$ Cholera is a water-borne disease. In many villages,access to clean,treated drinking water and proper sewage disposal is limited compared to urban areas,leading to a higher incidence of cholera.
