同意CEE只是第5题-_-||

第一题选C不选E，因为文中没有说birds may or may not learn from each other in a particular way（鸟学不学对方），只是对“鸟到底是学对方挑好的吃还是学对方避免毒食”进行了阐述，反驳了“鸟全部是学对方避免毒食”指出鸡就是挑好的吃（和哺乳动物一样了：挑好的吃）

 But Sherwin’s recent

 (50)     experiments with domestic

hens do not support the

notion that avian social

learning necessarily facili-

tates aversion to novel

 (55)     foods that are noxious or

toxic.

E. Demonstrator hens altered their behavior less obviously in response to noxious foods than in response to highly palatable foods.

"Sherwin’s research team speculated that ecological or social constraints during the evolution of this species might have resulted in there being little benefit from the social learning of unpalatability, for instance, selective pressures for this mode of learning would be reduced if the birds rarely encountered noxious or toxic food or rarely interacted after eating such food, or if the consequences of ingestion were minimal."

obvious=easy to see

That demonstrator hens altered their behavior towards noxious foods is less obvious because such chances are difficult  to see.

3C：E的reason是细节，通篇讲的是鸟怎样social learning而不是吃这个不吃那个
5D：E是错的，因为Demonstrator的确表现出了不舒服，是Observer没反应。D是对的，adversely说的就是这个不舒服的表现
6E：没争议

对这个解释仍然有疑问。题干是问，which of the following is true of the experiments ... by Sherwin's team。

既然是"true"，答案应该是实验的结果，是个fact。

但是这一段所描述的都是Sherwin's research team speculated that..

如果E是答案，那么叙述至少应该是"it is possible that demonstrator hens bla bla bla...."
