Explanation

Given:

ab = -5

Possible integer pairs:

(a, b) = (5, -1), (-1, 5), (1, -5), (-5, 1)

Given a - b > 0:

Only (5, -1) and (1, -5) satisfy this.

For (5, -1):

a > -1 is true, and b is odd is true.

For (1, -5):

a > -1 is true, and b is odd is true.

In both cases, |a| ≠ 5 for one of the cases.
