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 bowerbuilding styles of the local bowerbird population that has been studied most extensively.
(B) Young male bowerbirds are inept at bowerbuilding 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.
题目分析：在众多鸟的建巢风格中，其实共同点多于差异，没说，杀。B说年轻的鸟花很多年看它的长辈来学习筑巢风格，原文提过鸟用什么风格筑巢，信息和原文有交叉，留着。C说一种鸟缺乏其他鸟应该具备的tower及ornamentation等特点，没说，杀。D说bowerbird这种鸟只有在一些地方有，当地的鸟与外界很少有联系，有幻觉的选项，杀。E一些鸟的方言是学习来的不是基因的因素影响的，这个选项围绕的是鸟的song dialects谈的，原文围绕的是鸟的筑巢习惯谈的，范围驴唇不对马嘴，杀。
