问题 Rats and other animals need to be highly at tuned to social signals from others so that can identify friends to cooperate with and enemies to avoid.To find out if this extends to non-living beings,Loleh Quinn at the University of California,San Diego,and her colleagues tested whether rats can detect social signals form robotic rats.They housed eight adult rats with two types of robotic rat-one social and one asocial一for 5 our days.The robots rats were quite minimalist,resembling a chunkier version of a computer mouse with wheels-to move around and colorful markings.During the experiment,the social robot rat followed the living rats around,played with the same toys,and opened caged doors to let trapped rats escape.Meanwhile,the asocial robot simply moved forwards and backwards and side to side Next,the researchers trapped the robots in cages and gave the rats the opportunity to release them by pressing a lever.Across 18 trials each,the living rats were 52 percent more likely on average to set the social robot free than the asocial one.This suggests that the rats perceived the social robot as a genuine social being.They may have bonded more with the social robot because it displayed behaviours like communal exploring and playing.This could lead to the rats better remembering having freed it earlier,and wanting the robot to return the favour when they get trapped,says Quinn.The readiness of the rats to befriend the social robot was surprising given its minimal design.The robot was the same size as a regular rat but resembled a simple plastic box on wheels.“We'd assumed we'd have to give it a moving head and tail,facial features,and put a scene on it to make it smell like a real rat,but that wasn’t necessary,”says Janet Wiles at the University of Queensland in Australia,who helped with the research.The finding shows how sensitive rats are to social cues,even when they come from basic robots.Similarly,children tend to treat robots as if they are fellow beings,even when they display only simple social signals.“We humans seem to be fascinated by robots,and it turns out other animals are too,”says Wiles.James Wiles notes that rats________A.can remember other rat's facial featuresB.differentiate smells better than sizesC.respond more to cations than to looksD.can be scared by a plastic box on wheels

选项 A.can remember other rat's facial features
B.differentiate smells better than sizes
C.respond more to cations than to looks
D.can be scared by a plastic box on wheels

答案 C

解析本题目为细节题，考察具体细节。根据题干关键词James Wiles定位到第六七段，尾段尾句We humans seem to be fascinated by robots,and it turns out other animals are too,says Wiles.Wiles说：“我们人类似乎对机器人很着迷，事实证明其他动物也很着迷。”再结合尾段前面部分的阐述，会发现正确答案C respond more to actions than to looks对行动的反应多于对外表的反应，是原文的类似表达。干扰项A的can remember other rat's facial features能够记住其他老鼠的面部特征，与原文内容不符，原文第六段说的是假设赋予机器老鼠面部特征，那都不重要，属于偷换概念。选项B的differentiate smells better than sizes与体型大小相比，能够更好地区分气味，原文中只提到赋予机器老鼠真老鼠的气味，与原文不符，属于偷换概念。选项D的can be scared by a plastic box on wheels会被装有轮子的塑料盒子吓坏，文中机器老鼠只是装有轮子的塑料盒子，还是属于偷换概念。
