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: exists x_7: T(x_7). forall x_7: ~P_7(x_7) or R_6(x_7). forall x_7: P_7(x_7). forall x_7: ~Q_7(x_7).
exists x_7: T(x_7) and P_7(x_7) can be inferred via the existential conjunction rule. exists x_7: P_7(x_7) and T(x_7) can be inferred via the existential conjunction rule.
