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: ~p_16. p_16 <-> u_1. R_32(a_32) or q_24. forall x_32: R_32(x_32) -> S_32(x_32). q_24 -> S_32(a_32). p_3 -> ~S_32(a_32).
p_16 -> u_1 can be inferred via the biconditional elimination rule. u_1 -> p_16 can be inferred via the biconditional elimination rule. ~u_1 can be inferred via the biconditional elimination rule.
