These results confirmed that avian species can develop preferences for palatable food through social learning. 最后一句话,即E,both demonstrator and observer ,都可以显示出E的特点。
而且总觉得D中虽然是原文改写,但这句话是半截话,没说完,Even when demonstrator hens reacted with obvious disgust to a specific food,后面才是重点,via vigorous head shaking and bill wiping, there was no evidence that observers subsequently avoided eating that food
这半截话读的我有点憋屈哈,没表达完整的意思,even when。。。。
问题是:According to the passage, which of the following is true of the experiments on domestic hens conducted by Sherwin’s research team?
支持E
请探讨
