Consider the following premises. forall x_11: Q_11(x_11) -> T(x_11). forall x_11: ~P_10(x_11) or R_10(x_11). forall x_11: R_10(x_11) -> T(x_11). forall x_11: P_10(x_11) or P_11(x_11). forall x_11: P_6(x_11) or ~T(x_11). forall x_11: P_11(x_11) -> Q_11(x_11). Can we infer forall x_11: P_10(x_11) or P_11(x_11) from them?
That is one of the premises. Therefore, the answer is yes.
