What can be inferred from the following premises in a single inference step (ignoring inferences that add new predicates or constants)? s_1 and q_18. forall x_26: R_26(x_26) -> Q_10(x_26). forall x_26: P_26(x_26) or Q_26(x_26). forall x_26: P_26(x_26) -> R_26(x_26). forall x_26: Q_26(x_26) -> R_26(x_26).
s_1. q_18. forall x_26: P_26(x_26) -> Q_10(x_26). forall x_26: Q_26(x_26) -> Q_10(x_26). forall x_26: R_26(x_26).
