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.
Parasitic wasps use visual clues to calculate the size of a host egg.
问题分析：A说的是蛋的大小和下蛋行为之间的一个关系，和原文所谈关系类似，留着。
B说host insect是否有防御措施，原文没提，干掉。
C说wasp不同的物种下的蛋的数量不一样，显然无关，干掉。
D说下的蛋少了，和下的蛋多了哪种行为导致wasp死亡速度快，没说，杀。
E是wasp用视觉来计算egg数量多少，很扯的一个选项，干掉。
