※ 引述《lovekyoko (匹兹堡的天空)》之铭言： : 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? 题目只有3句话: (1) 某寄生虫准确地产卵在适当size的宿主egg上 (2) "假设" (注意是If) 产卵太多, 孵出的小虫会死 (3) "假设" (还是If) 产卵太少, 小虫还是会死 : (A) The size of the smallest host egg that a wasp could theoretically : parasitize can be determined from the wasp’s egg-laying behavior. 宿主的egg size可以从寄生虫产卵行为得知 (很合理) : (C) Parasitic wasps learn from experience how many eggs to lay into the eggs : of different host species. learn from experience 错 原文并没有提到任何"学习"的行为 : 有人可以解释一下 C错在哪吗 A又对在哪 : 题目最後给我的感觉 很像是经验法则 : 我觉得c很合理阿 : 谢谢 --
