The researchers suggest that capuchin monkeys, like humans, are guided by social emotions. In the wild, they are a co-operative, group-living species. Such co-operation is likely to be stable only when each animal feels it is not being cheated. Feelings of righteous indignation, it seems, are not the preserve of people alone. Refusing a lesser reward completely makes these feelings abundantly clear to other members of the group. However, whether such a sense of fairness evolved independently in capuchins and humans, or whether it stems from the common ancestor that the species had 35 million years ago, is, as yet, an unanswered question.
What can we infer from the last paragraph?
[A]Monkeys can be trained to develop social emotions.
[B]Human indignation evolved from an uncertain source.
[C]Animals usually show their feelings openly as human do.
[D]Cooperation among monkeys remains stable only in the wild.
題型識別:推理題(段落)
題干定位:最后一段
思路解析:段落推理題需要將四個選項和原文進行逐一比對,優先考慮和段落的觀點以及轉折處相關的選項。
選項分析:A最后一段第一句:研究表明像人一樣,猴子也是受社會情緒引導的。由此可知猴子是不需要訓練產生社會情緒的,這是猴子天生就會的。C在表達自我情緒的開放程度上,文章沒有對人和猴子進行比較。D錯誤的原因:文中明確表示合作穩定的前提是公平而不是在野外。B對應最后一段轉折。句式分析后簡化為:such a sense of fairness evolved from where is an unanswered question。human indignation對應such a sense of fairness, an uncertain source對應is an unanswered question,很完美的同義替換。
