What can be inferred from the following premises in a single inference step (ignoring inferences that add new predicates or constants)? p_1. p_7 -> ~p_1. p_7 <-> S_12(e_2). forall x_12: R_12(x_12) <-> S_12(x_12).
~p_7. p_7 -> S_12(e_2). S_12(e_2) -> p_7. forall x_12: R_12(x_12) -> S_12(x_12). forall x_12: S_12(x_12) -> R_12(x_12).
