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: U_4(c) -> p. p <-> T(c). forall x_1: T(x_1) or U_4(x_1).
p -> T(c) can be inferred via the biconditional elimination rule. T(c) -> p can be inferred via the biconditional elimination rule.
