What can be inferred from the following premises in a single inference step (ignoring inferences that add new predicates or constants)? Name the inference rule being used: exists x_11: ~P_11(x_11) or W(x_11). forall x_11: P_8(x_11) or ~W(x_11). forall x_11: P_11(x_11) or T(x_11). forall x_11: P_8(x_11) <-> T(x_11).
exists x_11: T(x_11) or W(x_11) can be inferred via the existential resolution rule. forall x_11: W(x_11) -> P_8(x_11) can be inferred via the universal rewriting rule. forall x_11: P_8(x_11) -> T(x_11) can be inferred via the universal biconditional elimination rule. forall x_11: T(x_11) -> P_8(x_11) can be inferred via the universal biconditional elimination rule.
