阅读下列短文,从每题所给的四个选项(A、B、C、D)中,选出最佳选项Phil Wise's heart raced as he opened one of the transport tubes. He and a team of scientists stepped back as a young Tasmanian devil(袋獾) named Oddity came out. Oddity took a cautious look around and then ran into the forest on Maria Island.Wise is a wildlife biologist from the Save the Tasmanian Devil Program. The scientists working with this program study Tasmanian devils, monitor their health, and track the devils found in the wild. Because a rare disease is reducing the number of devils, Oddity and 14 others were raised on a preserve and then brought to Maria Island to be released into the wild.Though they are raised in zoos all over the world, devils live wild only in Tasmania. They are important to the ecosystem because they eat dead animals they find, which helps clean up the environment. But a cancer called Devil Facial Tumor Disease (DFTD) is killing devils on mainland Tasmania, endangering the species. The goal of the scientists who released Oddity and the others was to create a population of disease-free Tasmanian devils on Maria Island. Oddity is a part of this "insurance population" of devils raised in zoos and wildlife preserves.The scientists chose Maria Island for the release because there is no DFTD there. It is separated from mainland Tasmania by the ocean. Devils from the rest of Tasmania can't get there, which prevents the facial disease from spreading.Wise and his fellow scientists monitored Oddity and the 14 other Tasmanian devils. The animals did so well that 13 more devils were released. The 28 original Tasmanian devils have reproduced; there are now around 80 devils. Scientists are now figuring out their next move. According to Wise, the focus will soon shift to moving some of the healthy devils back to mainland Tasmania.Wise says he is "extremely happy to know that animals are getting a chance to be free in the wild in an area that is free of DFTD. It is the ultimate aim of all who work to conserve threatened species."
