445.题目问有bright carotenoid-based coloration的雄性有以下什么特点?定位原文第6行" Studies of severalanimal species have shown that when choosing mates, females prefermales with brighter carotenoid-based coloration. "
the question is asking P, instead of general understanding of amber
the context said P is right in.....,, thus we shd not choose A as A said P is incorrect
错选B 原因:定位错误想当然,当时定位了 Yet women also gained power in comparison with their previous status, owning a higher proportion of real estate, (是19世纪有房子,问题问的是18世纪怎么样)--正确定位:Lebsock,...redirect...whether women gained or lost status in the nineteenth century as compared with the eighteenth century.(19C VS 18C)She concludes that while women gained autonomy in some areas, especially in the private sphere, they lost it in many aspects of the economic sphere--》所以18C的economic sphere更高才对
A:无关概念,题目没有提到detoxification的效率高低问题,也没有把它的效率和carotenoids的水平高低进行联系。
B:与分析答案方向相反,能够免疫疾病的动物应该体内carotenoids更多,因为它们不需要利用carotenoids来提抗疾病。
C:√由题干定位句分析可得:如果动物体内carotenoids较少,它们就是自身抵御疾病的能力较差,用掉了carotenoids来抵御疾病。
D:文章没有提到雄性对于伴侣的interest,只说了雌性对于它们的伴侣是否有兴趣
E:不在定位范围,且与文章信息不符。文章开头说所有动物都可以把carotenoids储存在不同的组织中。
