看了半天解释还是不太容易理解为什么就选择B。 请同学门帮忙理一理思路。非常感谢。
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?
(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.

这题大意就是说Tiger beetles在追逐昆虫时有时候会突然停下来
题目给了两个解释
1.他要歇一歇才能keep pace
2。昆虫飞太快时他不能适应changing visual information,然后会出现短暂失明，就不得不停下来

B就是对第二个的加强就是他在追的时候要不断停下来去adapt visual information同时也削弱了假说1

。。。
貌似是这样的吧

好像挺有道理的，不过GWD都说了没有正确答案，只有相对正确而已。谢谢LS的。

不知道我这样解释对不对：
B同时也支持假说1。因为alter course也可以使beetle不能keep pace，因此要停下来休息。

个人觉得这到题很纠结。。。。
