Answer to Question 1

Ans: D
Feedback:
Generally, contaminants can be thought of in three categories: chemical (lead, mercury, volatile organic compounds), biological (mold, anthrax, ricin), and radiological (radium, radon).

Answer to Question 2

Ans: D
Feedback:
A key concept for assessing risk is that the amount of risk equals the hazard times the exposure (risk = hazard  exposure). The presence of a hazard alone does not determine the amount of risk the hazard poses.
