3题我做的时候是E，但是后来想了一下，还是觉得C好些，E太片面了！文中是有解释，但是重点还是在讲述social learning ！

5题我做的时候觉得哪个都不对！就随便选了一个！看来把C或D改一下一定是答案了！有人给出的一份参考答案选了E，但E是明显错的！Even when demonstrator hens reacted with obvious disgust to a specific food, via vigorous head (60) shaking and bill wiping, there was no evidence that observers subsequently avoided eating that food.

由于Q5的答案没得选，偶后来选了A。

60行往后，there was no evidence that observers subsequently avoid eating that food，对应30行前后的叙述they subsequently avoided food associated with that color，a small number of observer的行为大约等同于no evidence；therefore，A比E可能好一些，虽然想的有点儿远了。

改的答案不算。

A是无关选项,这道题答案应该是丢失了.

But Sherwin's recent (50) experiments with domestic hens do not support the notion that avian social learning necessarily facilitates aversion to novel (55) foods that are noxious or toxic

Q3.C, Q5.A, Q6.E

Q5. (60) shaking and bill wiping, there was no evidence that observers subsequently avoided eating that food.

the red words mean that only small number of observers, rather than most of observers, avoided eating that food.

Q5. (60) shaking and bill wiping, there was no evidence that observers subsequently avoided eating that food.

the red words mean that only small number of observers, rather than most of observers, avoided eating that food.

Agree; even answer A is not so perfect, it is better than E.
