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.  erhaps 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.
求教！

tiger beetles在追击insect时会停下来有两种解释，一是因为要休息，二是因为跑起来看不清方向所以停下来找目标
A 捕食者捕食beetle时beetle的情况，无关选项（选项是说beetle chase insect的时候）
B beetle 很快的改变方向在追逐过程中，削弱第二个原因，向上追向下追停下来的频率一样与一、二原因无关
 也就是说选项B只削弱一个选项而并不加强另一个
C每次停下来时间相同，尽管insec在t跑，而且它会加速在停下来之后，加强了第一个，削弱了第二个
D无关（讲没追着就不追）
E我也觉得是无关，若真算有关也是能说削弱了第二个原因
