例三.指称(剑桥5/Test1/Reading Passage2)
One’s first inclination might be to argue that there must be some sort of built-in animal aggression instinct that was activated by the experiment， and that Milgram’s teacher-subjects were just following a genetic need to discharge this pent-up primal urge onto the pupil by administering the electrical shock. A modern hard-core sociobiologist might even go so far as to claim that this aggressive instinct evolved as an advantageous trait， having been of survival value to our ancestors in their struggle against the hardships of life on the plains and in the caves.
Q24. Some people may believe that the teacher-subjects’ behavior could be explained as a positive survival mechanism.
这是一道对错无判断题，以题干中的positive和 survival mechanism作为定位词，分别对应原文的“this aggressive instinct evolved as an advantageous trait， having been of survival value ”这一句中的advantageous 和survival value，因此可以判定题干的核心意思和原文的对应信息是同义转述。但是我们还需要确定题干中的teacher-subjects’ behavior和原文的对比信息this aggressive instinct在语义上是否对等。而要确定这一点，就必须要理解在原文中“this aggressive instinct”正是借助指称的衔接手段指代上文中的关于“teacher-subjects’ behavior”的具体描述，即：“teacher-subjects were just following a genetic need to discharge this pent-up primal urge onto the pupil by administering the electrical shock”。据此才可以判定题干的意思与原文完全一致，答案应为TRUE。
