43. Zoos have served both as educational resources and as entertainment. Unfortunately, removing animals from their natural habitats to stock the earliest zoos reduced certain species’ populations, endangering their survival. Today most new zoo animals are obtained from captive breeding programs, and many zoos now maintain breeding stocks for continued propagation of various species. This makes possible efforts to reestablish endangered species in the wild. Which one of the following statements is most strongly supported by the information above? A. Zoos have played an essential role in educating the public about endangered species. B. Some specimens of endangered species are born and bred in zoos. C. No zoos exploit wild animals or endanger the survival of species. D. Nearly all of the animals in zoos today were born in captivity. E. The main purpose of zoos has shifted from entertainment to education. 答案是B，但我认为B中的specimens在文中并没有相关信息，所以应该是无关。而D中的nearly all 应该起到和文中most相似的范围，不应该是范围错啊。请大家讨论下。 |
