Read the following passage and answer the question:
'The red wolf (Canis rufus) is one of the most endangered canids in the world. Once abundant throughout the Southeastern United States, its population was decimated by the early 20th century due to aggressive predator-control programs and loss of habitat. By 1980, the species was declared extinct in the wild. A captive breeding program was established with just 14 remaining individuals, and in 1987, a reintroduction program began. Today, a small, managed population of red wolves roams a protected area in eastern North Carolina, but the program faces significant challenges, including hybridization with coyotes and human-caused mortality.'
Which of the following statements best summarizes the key ideas in the passage?
-
A
The red wolf is a species that was once abundant but is now only found in captivity.
-
B
The red wolf, a critically endangered species, was saved from total extinction by a captive breeding and reintroduction program, though its recovery is still precarious.
-
C
The main threat to red wolves today is hybridization with coyotes in North Carolina.
-
D
Aggressive predator-control programs in the 20th century were solely responsible for the decline of the red wolf.
