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?
(A) 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.
(B) 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.
(C) The beetles maintain a fixed time interval between pauses, although when an insect that had been stationary begins to flee, the beetle increases its speed after its next pause.
(D) If, when a beetle pauses, it has not gained on the insect it is pursuing, the beetle generally ends its pursuit.
(E) When an obstacle is suddenly introduced just in front of running beetles, the beetles sometimes stop immediately, but they never respond by running around the barrier.
答案给的是C，我觉得B正确，C好像并没有削弱另一个假设？欢迎指教，谢谢……
谁可以帮我解答一下啊？？多谢了！
C说,即使虫子不动,甲壳虫也要停顿,说明不是因为虫子飞引起的.
然后说停完后速度加快,说明停可以积聚体力,支持了另一个说法.
原文两种说法 1）虫虫累了，所以停顿 2）虫虫跑的太快看不见了所以停顿
问哪个支持一方而削弱另一方
B的意思是虫虫的prey飞了它还跟着，说明虫虫能看见，削弱2）但下半句说在斜坡上停顿的时间间隔不变说明它不是因为累了才停顿，削弱1） 各打20大板
C 说无论prey是否逃跑，虫虫都保持一定的停顿时间间隔，说明不是看不见，削弱2）又说停顿后加快了，加强1）
做错的原因可能是削弱和加强的关系搞混了。
