Yellowstone National Park is located in the western United States and is home to a diverse range of wildlife. Probably for thousands of years, one species native to the area was the gray wolf. However, in the early 1900s, the park's wolf population was hunted and killed because they were seen as a threat to animals on the farms around the park, although the wolves rarely left the park area. They were extinct by the 1920s.

However, in 1995, the park started a plan to reintroduce wolves to the area, a move that would have a huge impact on the park's ecosystem. The plan involved capturing gray wolves from healthy populations in Canada and reintroducing them into Yellowstone. Before the reintroduction, the population of elk, a kind of deer, in the park was at an all-time high, and their eating habits had a very bad effect on the plant life. With the wolves' return, the elk population began to decrease as the wolves killed them, allowing the plant life to recover. This had a good effect on the rest of the ecosystem, as the increased plant life allowed for the return of other species, such as beavers and songbirds.

The fact that wolves were now back in the park also led to changes in the behavior of other species, such as coyotes and foxes, which began to avoid areas where wolves were present. This allowed small mammals like rabbits and rodents to increase their populations in those areas, which in turn attracted the birds which ate these creatures, like hawks and eagles.
the reintroduction of wolves is widely seen by ecologists as a success story for ormservation efforts, as it has helped to restore balance and diversity to the Yellowstone ecosystem. It has also been a valuable lesson in the way that species are connected within an ecosystem and the importance of preserving biodiversity. Farmers around the park are angry, however, that a threat has reappeared Questions: 25. What do we learn about gray wolves in paragraph 17 A. The population in the park died of natural causes in the early 1900s. B. It was not a native to the Yellowstone area. C. They killed a lot of farm animals in the early 1900s. D. People killed them to protect their cows, pigs, and chickens. 26. What happened after 1995? A. People brought gray wolves to live in the park again. B. A new species of wolf appeared in the park. C. The Yellowstone gray wolves returned to the park. D. People introduced a new species of wolf to the park. 27. Which of the following did NOT happen as a result of the reappearance of wolves in the park? A. The ecosystem was damaged. B. The elk population went down. C. Plant life increased. D. The songbird population rose. 28. In paragraph 3, the writer is giving examples of A. the dangers of reintroducing wolves B. the good effects from the reintroduction of wolves C. both the good effects and bad effects of the reintroduction D. some events not connected with the reintroduction 29. What animals might be threatened by the reintroduction of the wolves in the future? A. Elk and other mammals B. Rabbits and rodents C. Cows, pigs and chickens D. Many different species
