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: S(x_7). forall x_7: T(x_7). forall x_7: Q(x_7).
forall x_7: T(x_7) and Q(x_7) can be inferred via the universal conjunction rule. forall x_7: Q(x_7) and T(x_7) can be inferred via the universal conjunction rule. exists x_7: S(x_7) and T(x_7) can be inferred via the existential conjunction rule. exists x_7: S(x_7) and Q(x_7) can be inferred via the existential conjunction rule. exists x_7: T(x_7) and S(x_7) can be inferred via the existential conjunction rule. exists x_7: Q(x_7) and S(x_7) can be inferred via the existential conjunction rule.
