What can be inferred from the following premises in a single inference step (ignoring inferences that add new predicates or constants)? forall x_2: W_3(x_2) or Q_1(x_2). exists x_2: T_3(x_2) -> W_3(x_2). forall x_2: W_3(x_2) -> T_3(x_2). forall x_2: R_3(x_2) -> T_3(x_2). forall x_2: R_3(x_2) <-> Q_1(x_2).
exists x_2: R_3(x_2) -> W_3(x_2). exists x_2: T_3(x_2) <-> W_3(x_2). exists x_2: W_3(x_2) <-> T_3(x_2). forall x_2: R_3(x_2) -> Q_1(x_2). forall x_2: Q_1(x_2) -> R_3(x_2).
