So, as long as we find values that satisfy the given conditions (x > y and y > z), we can simply test the answer choices.
If x > y and y > z, then it could be the case that x = 1, y = 0, and z = 1
We'll now plug these values into the five answer choices....
(A) x − z = 1  (1) = 2
(B) x − y = 1  0 = 1
(C) y − x = 0  1 = 1
(D) z − y = (1)  0 = 1
(E) z − x = (1)  1 = 2
Answer: A
