Question

which best explains why protecting public health is an important duty of state government?
states that protect public health by maintaining correctional systems ensure the safety of their citizens.
states that protect public health by repairing infrastructure ensure the safety of their citizens.
states that protect public health by limiting outbreaks of disease ensure the safety of their citizens.
states that protect public health by promoting highway safety ensure the safety of their citizens.

Explanation:

Public health is directly related to disease prevention. Limiting disease outbreaks is a core public - health function. Correctional systems (law enforcement aspect), infrastructure repair (public works), and highway safety (transportation) are not as directly tied to public health as disease - outbreak limitation.

Answer:

States that protect public health by limiting outbreaks of disease ensure the safety of their citizens.
