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? B.In pursuing a swerving insect, a beetle alters its course while running and its pauses become more frequent as the chase progresses.
假设1 BETTLE不能够保持快的速度,需要休息 假设2 BETTLES 无法处理总是在变换的视觉信息 瞎了 B是正选 我对B的理解是 当BETTLES在追一个改变方向的昆虫的时候,B能够改变方向,停的次数也会更多。 能够改变方向证明没瞎,驳2。停的次数多证明不能保持快速,支持1 但是OG的解释是这个论点 provide information that strengthens the second hypothesis.the swerving pursuit and resulting continual adjustments appear to be forcing the bettle to stop with increasing frequency to sort out the erratic visual information.这里是支持2的 为什么了 请人解释,谢谢了 |
