题目选项分析

Tiger beetles are such fast runners that they can capture virtually any nonflying insect. However, when running toward an insect, the beetles intermittently stop, and then, a moment later, resume their attack. Perhaps they cannot maintain their pace and must pause for a moment's rest; but an alternative hypothesis is that while running tiger beetles are unable to process the resulting rapidly changing visual information, and so quickly go blind and stop.

Which of the following, if discovered in experiments using artificially moved prey insects, would support one of the two hypotheses and undermine the other?

【选项】In pursuing a moving insect, the beetles usually respond immediately to changes in the insect's direction, and pause equally frequently whether the chase is up or down an incline.

选项是否正确?

马上做出反应---证明不瞎。
上下坡停顿的一样多---证明不是因为累

就是说你在追别人 的时候,不管别人是什么速度,你都是一样的休息频率,证明,你不是累才休息,就是正常要停顿

马上做出反应-证明不瞎-削弱视力论
上下坡停顿一样多-不累-削弱体力论

能快速反应——不瞎;上下坡休息停顿时间一样——不累
所以都没有削弱

削弱假设2:“respond immediately”说明停顿不是因为“不能处理快速移动的图像信息”
削弱假设1:如果停顿是因为休息,那么上下坡的休息频率应该不同,但是选项说是相同的;

追猎物时,beetle根据猎物的位置变化马上转变respond immediately to changes(否定视力论),并且无论猎物上坡还是下坡都以一样的频率休息 pause equally frequently(否定体力论,假若支持累要休息,上坡休息应该更频繁)。此选项2个原因都否定了

Actually, this result provides both hypothesis are wrong. From author's argument, we know there are two reasons that make beetles have a moment's rest. 1. maintain their pace and 2. visual problem. Look at this choice, beetles usually respond immediately to changes in the insect's direction shows that beetles have no visual problem. Pause equally frequently whether the chase is up or down an incline shows that beetles can maintain their pace. Therefore, choice B is wrong.
