33. (31934-!-item-!-188;#058&005658)
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.
答案是C
为什么A 不对呀... 我选的时候在A 和C挣扎了半天...结果选了A......求NN指导...
