Challenge

Consider the four first-order predicate formulas
F1 : ∃x (∃u (∀v (P (u, v, x))) ⇒ ∃y (Q(x, y))) G : F1 ⇒ F2
F2 : ∃x (∀v (∃u (P (u, v, x))) ⇒ ∃y (Q(x, y))) H : F2 ⇒ F1

Task 5A. Determine whether G is valid or not. Either provide a proof that uses resolution to show validity, or else specify an interpretation that makes G false.

Task 5B. Determine whether H is valid or not. Either provide a proof that uses resolution to show validity, or else specify an interpretation that makes H false.
