What can be inferred from the following premises in a single inference step (ignoring inferences that add new predicates or constants)? p_1 <-> S_17(a_17). s. forall x_17: R_17(x_17) <-> S_17(x_17). R_17(a_17) -> ~s.
~R_17(a_17). p_1 -> S_17(a_17). S_17(a_17) -> p_1. forall x_17: R_17(x_17) -> S_17(x_17). forall x_17: S_17(x_17) -> R_17(x_17).
