Critical Reasoning
试题详情
题目：
Tiger beetles are such fast runners that they can capture virtually any nonflying insect. However, when running toward an insect, a tiger beetle will intermittently stop and then, a moment later, resume its attack. Perhaps the beetles 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 adequately 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?
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:
A、When a prey insect is moved directly toward a beetle that has been chasing it, the beetle immediately stops and runs away without its usual intermittent stopping.
B、In pursuing a swerving insect, a beetle alters its course while running and its pauses become more frequent as the chase progresses.
C、In pursuing a moving insect, a beetle usually responds immediately to changes in the insect’s direction, and it pauses equally frequently whether the chase is up or down an incline.
D、If, when a beetle pauses, it has not gained on the insect it is pursuing, the beetle generally ends its pursuit.
E、The faster a beetle pursues an insect fleeing directly away from it, the more frequently the beetle stops.
答案:
B
提问：
全文意思：探究beetles停下来是因为他看不清楚，还是他累了要休息；
我选了B，选项前半句话驳斥了“他看不清楚”，pause equally frequently whether…这里whether我把它翻译为不论，后半句话意思就是不论beetles追逐小虫是上升下降转弯，他都会频繁并等量的休息。（我当时C选项都没有看,觉得B肯定对）；C选项（increase speed after next pause）让我开始脑子脑补-原文说了cannot maintain their pace，(那会不会低速1KM/H可以不休息跑1小时，而高速5KM/H则只能不休息跑20分钟），那这个maintain pace太不accurate了。我肯定是没有找到对的点；有没有老师解答一下一般学术/GMAT中，建立一个实验的大致思维-从而解决问题；还有就是这道题应该怎么理解（哪里应该critical理解，哪里不是重点不用过分扣/脑补）

提问：
解析说反对hypo1是因为常理是追得快则累则追击时间短，the beetle increases its speed after its next pause说明这个beetles是在停下后才加速的，说明它需要停下看清prey提速了才判断是要加速，支持hypo2。
但是 如果是停下来后下一次加速 那也可能是休息购了 有更好的精力 而不是能看清楚目标 这样就支持第一个假设阿

提问：
原文说的是一种虫子在捕捉另一种虫的时候是用跑很快然后停在虫旁边，但是另一种解释是因为看不见所以才会停的，让选择支持其中一个否定另一个。看完完全蒙圈了，然后通过比较选了B。但是答案是C。。。。。这种题怎么做啊

提问：
第二项 我的观点：它在猎物过程中迅速对昆虫方向变化作反应，——驳斥了“眼睛瞎”。
同时，B还说它在追的过程中暂停频率相同。——支持了“需要休息” 第三项我的观点：它在休息之间的飞行时间固定，并说发现昆虫后将在下一段飞行中加速。——支持了“需要休息”。但，既没有支持也没有驳斥由于高速导致“眼睛瞎”。
