Parasitic wasps lay their eggs directly into the eggs of various host insets in exactly the right numbers for any suitble size of host egg. Id they laid too many eggs in a host egg, the developinig wasp larvae wyold compete with each otheer 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 conclusion can properly be drawn from the information above?
Answer:
the size of the smallest host egg that a wasp could theoretically parasitize can be deetermined from the wasp's egg-laying behavior.
很困惑，并没有任何地方提到behavior？怎么理解答案里面的behavior？

这个一眼看上去确实没有提到behavior

但是其他四个选项都有提到新信息，所以只有A是正确答案

为了其他人，我把其他四个答案也贴上来

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.

A. 虫虫可以产卵进去的最小寄生空间可以由虫虫的行为决定。少了原文讲的NUMBER,可是空间是SMALLEST，由原文的逻辑，可以立即想到，产卵的卵是可数的，一定会找到一个极小的空间，使产卵数量为1.这个虫虫只产一个卵的那个空间SIZE就是A项说的SMALLEST。此项出现极端词，SMALLEST，但这不是随便的极端词，它实际上指的是原文中NUMBER为1的特例，这是包含在原文的逻辑中的
