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: w -> Q_8(a_5). forall x_8: Q_1(x_8) <-> Q_8(x_8). w or Q_1(a_5).
R_1(a_5) -> w can be inferred via the rewriting rule. forall x_8: Q_1(x_8) -> Q_8(x_8) can be inferred via the universal biconditional elimination rule. forall x_8: Q_8(x_8) -> Q_1(x_8) can be inferred via the universal biconditional elimination rule.
