:bouncer2 have fun!
Lobsters usually develop one smaller, cutter claw and one larger, crusher claw. To show that exercise determines which claw becomes the crusher, researchers placed young lobsters in tanks and repeatedly prompted them to grab a probe with one claw - in each case always i.e. same, randomly selected claw. In most of hte lobsters the grabbing claw became the crusher. But in second, similar experiment, when lobsters were prompted to use both claws for grabbing, most matured with two cutter claws, even though each claw was exercised as much as the grabbing claws had been in the first experiment.
Which of the following is best supported by the information above?
A.young lobsters usually exercise one claw more than the other
B.most lobsters raised in captivity will not develop a crusher claw.
C.exercise is not a determining factor in the development of crusher claws in lobsters
D.cutter claws are more effective for grabbing than are crusher claws
E.young lobsters that do nit exercise either claw will nevertheless usually develop one crusher and one cuter claw.
OA will follow...

A)
Exercise one claw more than the other and that claw becomes the crusher
Exercise both equally and you get no crusher.
Excercise neither ... you don't know what happens (out of scope) so E is out
We know most lobsters have one cutter and one crusher ... so they must have excercised one claw more.

true guys...A is the answer.
This is a very typical CR of GMAT, you only need to be careful but the Q isn't too confusing, which is quite different from the CR of LSAT.
