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】When a prey insect is moved directly toward a beetle that has been chasing it, the beetle immediately turns and runs away without its usual intermittent stopping.

选项是否正确?

虫子飞过来,它跑走,说明能看见。without intermittent(间歇的) stopping,不停顿 ,说明不累。削弱both

不停顿,和文章所描述的停顿原因都扯不上关系了。无关。

削弱假设2:因为这里说“immediately turns”,说明间歇性停顿不是因为“不能处理快速移动的图像信息”
不能加强假设1:这个选项中没有体现出停顿和休息的关系

文中指出会停顿,这个实验设计里甲虫直接跑掉了,无关信息

说明可以快速处理变化的信息,驳斥了第二个假设,又因为立刻跑开没有通常的停顿,也驳斥了第一个假设
