Answer to Question 1

ANS: C
Although alternatives to whale products were available, whaling did not stop for most of the
commercial species until it became uneconomical for whalers. Information can be found in the section
Biological Resources.



Answer to Question 2

ANS: B
The ocean makes a large contribution to the world's need for petroleum and natural gas.
Approximately 35 of the world's crude oil came from the seafloor. Natural gas from the seabed
contributes about 28 of the world's usage. Information can be found in the section Physical
Resources
