问题 Some researchers claim that cetaceans—whales and dolphins—have culture, which the researchers define as the ability to learn from one another. Skeptics, however, demand clear evidence that cetaceans can acquire new behaviors through some form of social learning, preferably clear-cut instances of imitation or teaching. But such evidence is difficult to obtain. While few people doubt that captive cetaceans are adept at imitation or that they reproduce behaviors taught by researchers, biologists seeking insight into cetaceans’ behavior in their natural habitats must rely on deduction rather than experiments. If members of a particular group share behaviors that do not result from genetic inheritance or environmental variation, then they have almost certainly learned them by watching, following, or listening to other animals. [br] The passage suggests which of the following about captive cetaceans?
选项 A、Whether they are engaged in social learning is a subject of disagreement among biologists.
B、Their ability to imitate new behaviors is more extensive than that of noncaptive cetaceans.
C、They exhibit few behaviors that have not also been observed in cetaceans in their natural habitats.
D、They appear to adopt new behaviors more quickly than noncaptive cetaceans.
E、They exhibit tendencies that suggest a capacity for the kind of behavior that qualifies as cultural.
答案 E
解析 细节题。以题干中的captive cetaceans作为定位点，文章中只在第四句的while部分出现了captive cetaceans，这里认为captive cetaceans可以很熟练地模仿和重现行为，换言之就是它们有学习能力，而这种能力在文中被研究者定义为culture。特别注意的是这里的qualify的释义为：be qualified as something means to have all the features that are needed to be that thing，被称作是。
