77.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，potions 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．

答案给的是A.通过的wasp's egg-laying behavior可以决定The size of the smallest host egg。

看到答案解释后，仍然觉得选C。

请牛牛指教一下，为什么A比C更能从上文中推断出。

谢谢。

偶不是牛牛，呵呵。

我的理解是：wasps放的egg太多不行太少也不行，要刚刚和host egg 的大小匹配才行。所以通过wasp egg的数量能估计出host egg的大小。最佳答案Ａ

至于答案Ｃ，"learn from experience"在原文中没有提到。

The original sentence even did not mention how wasp  learned  to lay the exact number of eggs.

It just tells you a fact of the Parasitic wasps 's egg-laying behavior.
