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_6: P_6(x_6). forall x_6: ~W(x_6) or T(x_6). forall x_6: P_6(x_6) -> W(x_6).
exists x_6: W(x_6) can be inferred via the existential modus ponens rule.
