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.According to Quinn,the rats released the social robot because they________A.tried to practice a means of escapeB.expected it to do the same in returnC.wanted to display their intelligenceD.considered that an interesting game

选项 A.tried to practice a means of escape
B.expected it to do the same in return
C.wanted to display their intelligence
D.considered that an interesting game

答案 B

解析本题目为细节题，考察具体细节。根据题干关键词Quinn和the rats released the social robots往下定位到第四五段，第五段最后一句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.Quinn说：这可能会让老鼠更好地记住早些时候已经释放了机器人，并希望机器人在它们被困住时能回报它们的恩惠。正确答案B expected it to do the same in return是原文的同义替换。干扰项A的tried to practice a means of escape试图尝试一种逃跑的方法，原文并未提及，属于无中生有。选项C的wanted to display their intelligence想要展示它们的智慧，文中并未提到，属于无中生有。选项D的considered that an interesting game觉得是个有趣的游戏在原文当中也没有体现，属于无中生有。
