When a caterpillar emerges from the egg on a tree branch, it immediately climbs upward until it finds a leaf bud to eat. Biologists thought that this behavior displayed an innate tendency to move in the direction opposite to the pull of gravity. In a recent experiment, a strong light source was placed at the bottom of a tree, and caterpillars, after hatching, climbed downward.
Which of the following hypotheses is best supported by the statements given?
Caterpillars have an innate tendency to move in the direction of gravity.
Newly hatched caterpillars are unable to see in the dark.
Newly hatched caterpillars move towards the strongest light source in the environment.
Newly hatched caterpillars move toward the leaf bud nearest to them.
The eyes of newly hatched caterpillars become less sensitive to light over time.
BE的意思是一样的,如果不感光,应该向相同的方向去

When a caterpillar emerges from the egg on a tree branch,当C出现在树枝上的卵旁边时
emerge from sth,从某处出现,如:She finally emerged from her room at noon. 中午,她终于从屋里出来了。
Which of the following hypotheses is best supported by the statements given?下列哪个假设最能得到所给陈述的支持? = 根据上面的陈述,下面哪个是最准确的?
找到两个experiment的共通性就能得到结论
这题是 resolve paradox 题型
这类题的特点是:没有结论,摆出两件矛盾的event
答案要co-exist however前后的内容
所以选C 在however之前也成立 however之后也成立

看题目以为是类比加强,可选项像是must be true 的题。
