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_4(x_7). forall x_7: Q_1(x_7). forall x_7: W(x_7).
forall x_7: Q_1(x_7) and W(x_7) can be inferred via the universal conjunction rule. forall x_7: W(x_7) and Q_1(x_7) can be inferred via the universal conjunction rule. exists x_7: T_4(x_7) and Q_1(x_7) can be inferred via the existential conjunction rule. exists x_7: T_4(x_7) and W(x_7) can be inferred via the existential conjunction rule. exists x_7: Q_1(x_7) and T_4(x_7) can be inferred via the existential conjunction rule. exists x_7: W(x_7) and T_4(x_7) can be inferred via the existential conjunction rule.
