Read the following passage carefully and answer the question given below. Earth in home to more than 16,000 species of plants, animals, fungi, and algae that are currently listed as endangered on the IUCN Red List of Threatened species. In the U.S. alone, nearly 700 species of animals and 900 species of plants are considered threatened or endangered. Given that human-made threats-such as habitat fragmentation, overhunting, overfishing, global warming, invasive species and pollution-are the major drivers of modern extinctions and population declines, the preservation and recovery of endangered species depend on human awareness and intervention. Endangered Species Day is observed each year on the third Friday of May as a way to both raise awareness of the continued underline("plight") of endangered species and celebrate those that have recovered becuase of conservation efforts. The U.S. Endangered Species Act of 1973 has been credited with the recovery and protection of several prominent American species, including the bald eagle, the American alligator, and the gray wolf. Globally, many governments, non-governmental organizations, and grassroots efforts have made great strides to protect our natural heritage, though the fight to preserve biodiversity is ever ongoing. Which of the following species was recovered by the help of The U.S. Endangered Species Act of 1973 ?
