标题: 求助一道OG逻辑~ [打印本页] 作者: 陌下清风 时间: 2010-8-19 13:05 标题: 求助一道OG逻辑~ .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 would 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 the host egg.
这道题的正确答案为A，但是我觉得C是对的....是不是我的理解有问题...大家来帮助我看一下吧，谢谢喽`~作者: dingshuaijun 时间: 2010-8-19 14:48

题目的信息：寄生的黄蜂下的蛋会到适合的SIZE的宿主的蛋里，如果下蛋多了，黄蜂的幼体就会为了空间和营养竞争，如果下蛋少了，一些蛋就会腐烂从而杀死黄蜂的幼体 归纳题只能有原文的信息不能有新的信息·· (A) The size of the smallest host egg that a wasp would theoretically parasitize can be determined from the wasp's egg-laying behavior.黄蜂理论上寄生的最小的宿主蛋的SIZE 可以被黄蜂的下蛋的习惯所决定 (C) Parasitic wasps learn from experience how many eggs to lay into the eggs of different host species. 寄生的黄蜂学到有多少蛋下在不同的宿主物种（different host species.无关）
