Question from mba.com practice test 1

by pranavc » Thu Jul 03, 2008 7:59 pm
Parasitic wasps ay 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 the egg.

Any input on the above will be highly appreciated. Thanks in advance.

The OA is A but I can't for the life of me figure out why.

stimulus:PW lay eggs in exactly the right number according to the size of the host egg; 2many eggs-death;2less eggs-decay.

A:It says the smallest size of the host egg can be determined from the PW egg laying behaviour.This is possible as PW lay eggs according to the size of the host eggs.i.e Less eggs laid-smaller is the host egg.

B:It doesnt say anything about the host defence .
C:It doesnt say anything about PW experience or how they learn.
D:It doesnt say anything about the rate at which death will occur.
E:Not applicable!!

Note:The second part of the stimulus states what would happen "IF" they lay more or less eggs than required.It cites a situation.But the first part already says they lay eggs in right number.And out of all the options given ,A is the one that supports the most.

I hope this helps..
Let me know if not clear..

All the best!
