题目选项分析

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?

【选项】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.

选项是否正确?

当奔跑的甲虫被突然给予障碍物,甲虫有时候会立刻停,但从不围着障碍物跑. 有时候这样的表述无法被用作实验结论,lack of clarification,同时这句话整个意思也和题目没什么太大关系
