(1) x - 5 > y - 5
(2) x^2> xy
Statement 1:
Adding 5 to both sides, we get:
x > y.
Thus, the answer to the question stem is YES.
Statement 2:
Case 1: x=1 and y=0, with the result that x² = 1² = 1 and xy = (1)(0) = 0
In this case, x > y, with the result that the answer to the question stem is YES.
Case 2: x=-1 and y=0, with the result that x² = (-1)² = 1 and xy = (-1)(0) = 0
In this case, x < y, with the result that the answer to the question stem is NO.
Since the answer is YES in Case 1 but NO in Case 2, INSUFFICIENT.
The correct answer is
A.
