11.   Less than 50 percent of a certain tropical country’s wildlands remains intact. Efforts are under way to restore biological diversity in that country by restoring some destroyed wild habitats and extending some relatively intact portions of forests. However, opponents argue that these efforts are not needed because there is still plenty of wildland left.

Which of the following, if true, most significantly weakens the argument of the opponents of conservation efforts?

(A) As much, if not more, effort is required to restore a wild habitat as to preserve an intact habitat.

(B) The opponents of restoration efforts are, for the most part, members of the wealthier classes in their own villages and cities.

(C) Existing conservation laws have been very effective in preserving biological diversity within the wildlands that remain intact.

(D) For many tropical species native to that country, the tropical wildlands that are still relatively intact do not provide appropriate habitats for reproduction.（D）

(E) If a suitable population of plants and animals is introduced and is permitted to disperse and grow, tropical habitats can most certainly be restored.    請問(A)是什麼意思？為什麼要選(D)?

我是这样想的：

A）恢复野外居住地所需要的努力与保护原始居住地所需要的努力一样多。

　　并没有说到有没有必要保护这两种居住地，所以A不好。

D）“没有足够的居住地来繁衍”正好提供了一个理由要保护居住地，反对“反对者”。

　　所以选D。
