What can be inferred from the following premises in a single inference step (ignoring inferences that add new predicates or constants)? forall x_12: Q_12(x_12) <-> Q_8(x_12). Q_8(a_5) <-> t. forall x_12: ~P_12(x_12). forall x_12: P_12(x_12) <-> Q_12(x_12).
Q_8(a_5) -> t. t -> Q_8(a_5). forall x_12: Q_12(x_12) -> Q_8(x_12). forall x_12: P_12(x_12) -> Q_12(x_12). forall x_12: Q_8(x_12) -> Q_12(x_12). forall x_12: Q_12(x_12) -> P_12(x_12). forall x_12: ~Q_12(x_12).
