请教OG逻辑的23题

23. 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.

逻辑链是：
P：同一种族的不同居住地的鸟造的鸟巢有不同的风格
C：建造风格都是学习来的而不是遗传来的。

答案是B~~但是我的想法是：这种因果关系的问题，要加强它，不是要建立起前提和结论的因果关系才对吗？就是证实两者确实有因果关系
但是B答案不是就只是在证实了专家结论的正确，没有把它和前提建立因果关系吗？这样为什么还对？

不知道大神们懂不懂我的逻辑误区？怕讲得不清楚。。。但是我真的纠结了很久很久很久，请大神把我从牛角尖中拔出来吧！！

by the way，我是看了毕出的逻辑书，他定义为这种是果因问题，P是果，C是因，因为C所以P，要加强就只要1、证明两者的因果关系     2、或者证明P不是由其他原因造成。。。。

你好
此题是个加强题，不是weaken题，你的思路是反着的。

如果是加强的话，首先确定Logic Line:
即: same specie birds build different style nests>>>>>the skill is acquired from learning instead of gene
A\D 是反的，即觉得the skill is acquired from gene, C有一点点反，因为most of other species know the skills of towers and ornamentation
B is tempting, 说young male birds watch old male birds, 看起来是支持结论，但是 watch does not mean learn, it's not direct enough

E seems out of scope, but it gave an another skill, which is singing, to illustrate that some skills can be learned among these birds.
