When raised with a small number of conspecifics [members of the same species], guppies were quicker to locate food by following a trained adult guppy than were guppies raised in large groups. This counterintuitive finding is explained by the fact that guppies reared in the high-density condition were less likely to shoal [swim in a group] with others and, therefore, were less likely to learn the benefits of social learning

Which of the following hypothetical expectations would make the finding mentioned in the passage "counterintuitive"?
C That guppies would be more likely to shoal in conditions of low population density than they would be in conditions of high population density
D That social learning among guppies would increase in conditions where guppies are exposed to a greater number of conspecifics

key：D,
请教大家 和原文对照的话不应该是C 吗？    题目不就是在问啥让人感觉counterintuitive， 为什么要对原文取反呢？
是我理解错了还是答案错了....源自kmf ppplus模考



Postmodern music often explores the confluence of genres previously thought incompatible. The boundaries between "popular music" (which often draws from a variety of cultures) and what is commonly considered "art music" (which often draws from a narrower cultural spectrum) are frequently blurred or obliterated. Although art music has reflected some mixing of cultures for centuries, and some art music composers in the first half of the twentieth century made use of genre mixing, postmodern music is distinct from pre-1960s art music compositions.  

The highlighted reference to "art music" serves primarily to
D address a possible objection to the author`s central point about postmodern music
E question a particular assumption about the distinguishing features of postmodern music

key：D
错选E。
高光是art music，而不是although..., .....这一整个句子， 如果是后者，可以解决问题。。但是只有art music，这明摆着就是砸场子反驳前面观点的啊？


不知道自己的思路哪里出了问题.. ... 请教高人

感谢！！

1. 问的是哪种假设的期望（hypothetical expectations）使上述发现违背常理。简单点说，就是发现了一个现象，有违常理，题目问的是这个“常理”是什么。C给的是这种现象的explanation
2. 这种题目找逻辑上一层，里面art music的逻辑上一层是整个句子，考的是局内关系，就是让步转折。让步是在qualify的基础上使结论更充分，不是在question结论.
