What can be inferred from the following premises in a single inference step (ignoring inferences that add new predicates or constants)? forall x_10: P_10(x_10) or Q_10(x_10). forall x_10: ~P_10(x_10) or R_10(x_10). Q_10(a_8) <-> u_2. R_10(a_8) -> u_2.
Q_10(a_8) -> u_2. u_2 -> Q_10(a_8). forall x_10: Q_10(x_10) or R_10(x_10).
