What can be inferred from the following premises in a single inference step (ignoring inferences that add new predicates or constants)? Q_15(a_12) -> w. forall x_15: W_3(x_15) <-> Q_15(x_15). w -> W_3(a_12).
Q_15(a_12) -> W_3(a_12). forall x_15: W_3(x_15) -> Q_15(x_15). forall x_15: Q_15(x_15) -> W_3(x_15).
