PREP中的题！！谢谢！！[5]

Parasitic wasps lay their eggs directly into the eggs of various host insects in exactly the right number for any suitable size of the 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 spaces. 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?

正解:The size of the smallest host egg that a wasp could theoretically parasitize can be determined from the wasp’s egg-laying behavior.
