P1-48

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.

正确答案是A


这题我做错了，选了C。 我现在觉得A是对的
C讲到了 learn from experience，这个感觉讲的有点太远，文章只说了它们有这样的发现，但是不一定是从经验中习得的。learn from experience。。 不能be drawn...

再看A选项：The size of the smallest host egg that a wasp could theoretically parasitize can be determined from the wasp's egg-laying behavior.  翻译下：wasp理论上能够寄生的最小的宿主egg的大小可以从wasp的下蛋行为确定，我觉得这里的can be determined... 中这个determine的主体可能是科学家之类的，也就是说，我们可以从wasp的下蛋行为看出它能寄生怎样的蛋里。前面有提到如果下蛋太多或者下蛋太少它都会死。 题干中有exactly the right numbers for any suitable size of host egg 这里我觉得这个any suitable size, 那么smallest就是any中的其中一种，算是具体化的了表达，也是正确的。


我这样的理解不知道对不对~~ 麻烦NN们指正~~
