A very way to test data presented to show the real true state of an valid argument!

Destructive Dilemma

A formal argument in logic in which it is stated that

1. P=>Q and R=>S (where => means "implies"), and

2. Either not-Q or not-S is true, from which two statements it follows that either not-P or not-R is true.
