Consider the following premises. forall x_10: Q_1(x_10) -> Q_10(x_10). forall x_10: Q_1(x_10) or Q_4(x_10). forall x_10: T(x_10) or ~Q_10(x_10). exists x_10: U(x_10). forall x_10: Q_4(x_10) -> T(x_10). Can we infer exists x_10: U(x_10) from them? If possible, name the inference rules being used at each step.
That is one of the premises. Therefore, the answer is yes.
