Question: what is the fastest way to solve?
See attached for "proposed solution".
Stem
A mistake would be to consider that we would get the answer is |y|>|z|, because x - z and x - y would be totally different beacuse of sign changes
Statement A
Tells us about magnitude of z and y but we do not know about their signs or the sign of x
Statement 2
Tells us about the sign of x but not about x but not about x and y or the magnitudes
Combined
We still do not know about signs of z and y Hence Insuff
Note: If all the numbers were >0 , then the answer would have been A
