Consider the following premises. exists x_6: Q_1(x_6) -> R(x_6). forall x_6: P_6(x_6) -> T_2(x_6). forall x_6: T_2(x_6) -> R(x_6). forall x_6: P_6(x_6) or Q_6(x_6). forall x_6: Q_6(x_6) -> T_2(x_6). Can we infer forall x_6: Q_6(x_6) -> T_2(x_6) from them? If possible, name the inference rules being used at each step.
That is one of the premises. Therefore, the answer is yes.
