Answer to Question 1

ANS: C
Polychlorinated biphenyls are another type of chlorinated hydrocarbon. The ingestion of the chemical
by these dolphins is thought to have weakened their immune system which allowed for a virus to
infiltrate them. Information can be found in the section Marine Pollutants May Be Natural or Human
Generated.

Answer to Question 2

ANS: D
The insoluble components are also responsible for killing many larva populations because they cannot
withstand the oil pollutants. Information can be found in the section Marine Pollutants May Be
Natural or Human Generated.
