48.(34221-!-item-!-188;#058&007550)

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.

记得XDF好像第一个就讲的这道题，这道题用排除法，B,D 什么缺乏抵抗力喽，视觉线索喽无关，D么也是一个无关比较，C么的确是易错项，但是注意，它结尾说的是不同的种群，即寄生黄蜂通过它们的经验决定不同的种群下不同数量的蛋，而文章强调的是不同大小的host egg..(不知道怎么翻译），反正就是文章强调的是size~这样想，答案就很明显了～
