Answer to Question 1

Ans: A
Physical hazards to health include radiation, lead, other heavy metals, and noise. Biologic hazards can be infectious agents, insects, animals, and plants. Use of earplugs will reduce noise and damage to hearing. Encouraging microwave use is counterproductive to reduction of physical hazards. Reducing the mosquito population and removing dead plants are examples of preventing biologic hazards, not physical hazards.

Answer to Question 2

Ans: A
Pollution is a rate function involving a quantity of pollutant introduced over a period of time. This rate is directly correlated with population size. The capacity of the environment to assimilate pollution is not unlimited; in fact, pollution of the environment occurs when pollutants overwhelm the capacity of the environment to assimilate them without being thrown out of balance. Industrial development increases the number of pollutants and environmental insults. If the population moves, both the nature and the intensity of an environmental problem can shift. Thus, one area may improve; another may become more polluted.
