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: forall x: S_3(x) -> Q_2(x). Q_2(a_10) -> p. p -> S_3(a_10). forall x: Q_2(x) -> S_3(x).
Q_2(a_10) -> S_3(a_10) can be inferred via the transitivity rule. forall x: S_3(x) <-> Q_2(x) can be inferred via the universal biconditional introduction rule. forall x: Q_2(x) <-> S_3(x) can be inferred via the universal biconditional introduction rule.
