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: T_2(e) or p_1. Q(e) or ~p_1. forall y: Q(y) <-> T_2(y).
p_1 -> Q(e) can be inferred via the rewriting rule. forall y: Q(y) -> T_2(y) can be inferred via the universal biconditional elimination rule. forall y: T_2(y) -> Q(y) can be inferred via the universal biconditional elimination rule.
