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。

Today most new zoo animals are obtained from captive 只是说新增的动物是人工培育的。言下之意是老的动物还是野生的，比如一个极端的例子，乌龟，它丫能活到动物馆成立到现在， 还是最初捕获的那一只。b把范围缩小了，更加准确了

首先B中的specimens在文中and many zoos now maintain breeding stocks for continued propagation of various species.中也有体现，而且不应该由词的形式上的一致来判断无关有关，应该以意思和内涵为准。

而且注意这一题是conclusion题，不是加强，D的nearly all如果是加强可以起到作用。但从文中信息无法推出，nearly all才绝对了。原文的说法是比较保守的，makes possible efforts to reestablish endangered species in the wild. 你揣摩一下语气。conclusion题一要谨慎和保守，不要激进。
