[讨论]OG-175再讨论（看过前人的帖子了）

175. Parasitic wasps lay their eggs directly into the eggs of various host insects in exactly the right numbers for any suitable size of host egg. If they laid too many eggs in a host egg, the developing wasp larvae would compete with each other to the death for nutrients and space. If too few eggs were laid, portions of the host egg would decay, killing the wasp larvae.

Which of the following conclusions can properly be drawn from the information above?

(A) The size of the smallest host egg that a wasp could theoretically parasitize can be determined from the wasp's egg-laying behavior.
(B) Host insects lack any effective defenses against the form of predation practiced by parasitic wasps.
(C) Parasitic wasps learn from experience how many eggs to lay into the eggs of different host species.
(D) Failure to lay enough eggs would lead to the death of the developing wasp larvae more quickly than would laying too many eggs.
(E) Parasitic wasps use visual clues to calculate the size of a host egg.

网络很慢看过以前的NN们讨论的2个帖子，说实话我怎么觉得好象说的不是太透彻。我选错了，ETS的解释Comparing two host eggs in which parasitic wasps have laid different numbers of eggs, it is theoretically possible laid different numbers of eggs, it is theoretically possible to determine what size of host egg would be required for a single wasp egg. This would be the smallest egg the wasp could parasitized. 我看了好几遍才有模糊的感觉。我的理解：A 是要判断最小的寄主蛋理论上应该是多大尺寸能否从黄蜂下蛋行为中推出？因为寄主蛋的大小不同黄蜂蛋数量也不一样，比如说1立方厘米的寄主蛋可下4个黄蜂蛋，而2立方厘米的寄主蛋可下8个黄蜂蛋，这样从理论上就可以算出只能容纳一个黄蜂蛋的寄主蛋是多大，即size of the smallest host egg. A选项里的wasp's egg-laying behavior是抽象得够可以了。

我不知道这样的思路对不对，是否太繁琐太费解了？哪位还有更简单易懂的理解思路请一定告诉我啊，谢谢！
