Question 20 • Environmental Science A

endangered
B
threatened
C
extinct
D

Explanation

The Endangered Species Act classifies a species as endangered when it is in danger of extinction throughout all or a significant portion of its range. Rhinoceroses have declined to near extinction, so the best choice is “endangered.” “Threatened” means likely to become endangered in the foreseeable future, while “extinct” means no individuals remain.
