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: Q_4(a_10) <-> W_4(a_10). forall y: Q_4(y) -> W_4(y).
Q_4(a_10) -> W_4(a_10) can be inferred via the biconditional elimination rule. W_4(a_10) -> Q_4(a_10) can be inferred via the biconditional elimination rule.
