A) No action should be taken until absolute proof of harm exists
B) Action should be taken to prevent harm even in the absence of scientific
certainty
C) Only cost-benefit analysis should guide decisions
D) Only federal agencies can make environmental decisions
Correct Answer: B
Rationale: The Precautionary Principle advocates for proactive measures to
protect the public from environmental hazards even when definitive scientific
evidence of harm is lacking.
5. Which of the following is a primary federal agency that works with the Hawaii
DOH on environmental health issues?
A) USDA
B) EPA
C) FDA
D) All of the above
Correct Answer: D
Rationale: The EPA (environmental regulation), FDA (food, drugs), and USDA

A) Any chemical contaminant in water
B) An organism that transmits disease-causing pathogens
C) A type of air pollutant
2
,D) A radioactive isotope
Correct Answer: B
Rationale: A vector is a living organism, such as mosquitoes, ticks, or rodents, that
transmits infectious diseases between hosts.
7. Which of the following is NOT typically considered a component of the "built
environment" relevant to environmental health?
A) Housing quality
B) Road design and walkability
C) Ocean currents
D) Water supply infrastructure
Correct Answer: C

contamination.
11. Hawaii's isolation makes it particularly vulnerable to:
A) Invasive species introduction that affects ecosystems and health
B) Excessive cold weather
C) Lack of solar radiation
D) Overabundance of natural predators
Correct Answer: A
Rationale: Hawaii's remote location increases the risk of invasive species, which
can disrupt ecosystems, agriculture, and vector-borne disease patterns.
12. The "Epidemiological Triangle" consists of:
A) Host, Agent, Environment
B) Doctor, Patient, Hospital
C) Air, Water, Land
D) State, County, Federal
Correct Answer: A
Rationale: The Epidemiological Triangle describes the interaction between host,
