What can be inferred from the following premises in a single inference step (ignoring inferences that add new predicates or constants)? Q_8(a_5) <-> t_1. forall x_8: P_8(x_8) <-> Q_8(x_8). forall x_8: ~P_8(x_8).
Q_8(a_5) -> t_1. t_1 -> Q_8(a_5). forall x_8: P_8(x_8) -> Q_8(x_8). forall x_8: Q_8(x_8) -> P_8(x_8). forall x_8: ~Q_8(x_8).
