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.
