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: exists x_8: T_1(x_8) -> R_4(x_8). forall x_8: S_1(x_8) or ~Q_8(x_8). forall x_8: Q_8(x_8). forall x_8: S_1(x_8) -> R_4(x_8).
forall x_8: Q_8(x_8) -> S_1(x_8) can be inferred via the universal rewriting rule.
