Male bowerbirds construct elaborately decorated nests, or bowers. Basing their judgment on the fact that different local populations of bowerbirds of the same species build bowers that exhibit different building and decorative styles, researchers have concluded that the bowerbirds’ building styles are a culturally acquired, rather than a genetically transmitted, trait. Which of the following, if true, would most strengthen the conclusion drawn by the researchers?

(A) There are more common characteristics than there are differences among the bower-building styles of the local bowerbird population that has been studied most extensively

(B) Young male bowerbirds are inept at bower-building and apparently spend years watching their elders before becoming accomplished in the local bower style.
           

(C) The bowers of one species of bowerbird lack the towers and ornamentation characteristic of the bowers of most other species of bowerbird.

(D) Bowerbirds are found only in New Guinea and Australia, where local populations of the birds apparently seldom have contact with one another.

(E) It is well known that the song dialects of some songbirds are learned rather than transmitted genetically.

答案是B
请问：D选项，OG解释说既没有加强也没有削弱？看不明白，为什么不可以是加强，支持作者认为它们的skills是culturally acquired？

问题是D选项里，有个are found only in New Guinea and Australia, 这个就跟原文不符，原文并没有说这个鸟只能在这两个地区生活！原文中是说different locations, 如果D选项改成Bowerbirds are found in different loacations, where local populations of the birds apparently seldom have contact with one another. 这样D就加强了！

我刚又想了一下，是不是因为D没有加强结论啊，seldom contact不能支持skills 是culturally acquired...
