(B) In pursuing a moving insect, the beetles usually respond immediately to changes in the insect's direction(反對假設2), and pause equally frequently whether the chase is up or down an incline(並未支持假設1：因為假設1中cannot maintain pace->pause；但此處pause與pace無關).

(C) The beetles maintain a fixed time interval between pauses(並未支持假設1：理由同上), although when an insect that had been stationary begins to flee, the beetle increases its speed after its next pause(支持假設2：因為the beetle會執行chase的動作是因為他認定insect仍位於該處，因為無法及時更新visual in formation所以不知道insect begins to fly).

(C)為正確選項

OG里这道题的正确答案好像是B.

OG里头的C选项和PREP的B相同。

OG里头的B是这样滴：

In pursuing a swerving insect, a beetle alters its course while running and its pauses become more frequent as the chase progresses.

这道题是OG11黄皮那本的diagnostice test里的。

至于答案为什么不一样，因为题干一样，而每个选项的具体内容是不一样的！

B 错的原因：

 

(B)In pursuing a moving insect, the beetles usually respond immediately to changes in the insect's direction (weaken假设二à没有瞎，因为可以立刻会应昆虫方向的改变), and pause equally frequently whether the chase is up or down an incline (无法support假设一
            àpause equally frequently whether the chase is up or down,如果是因为没劲停的话，不可能跑上下坡有相同频率的停。)
