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?

(A) Caterpillars have an innate tendency to move in the direction of gravity.

(B) Newly hatched caterpillars are unable to see in the dark.

(C) Newly hatched caterpillars move towards the strongest light source in the environment.

(D) Newly hatched caterpillars move toward the leaf bud nearest to them.

(E) The eyes of newly hatched caterpillars become less sensitive to light over time.

答案 C: 此选项结合了信息1和信息2，caterpillar的move一定受到光的影响，而且确实是哪的光强就往哪怕。

信息1：When a caterpillar emerges from the egg on a tree branch, it immediately climbs upward until it finds a leaf bud to eat.

à信息2：In a recent experiment, a strong light source was placed at the bottom of a tree, and caterpillars, after hatching, climbed downward..

我想问信息1怎么体现出caterpillar的move受到光的影响？

信息一就是隐含了一个常识啊，阳光不都是从上到下射下来的吗？

我覺得看最後那句話吧  a strong light source was placed at the bottom of a tree, and caterpillars, after hatching, climbed downward.


這個説明不是往衝力相反的方向，而是去光強烈的地方。
