Consider the following premises. forall x_13: ~P_13(x_13). exists x_13: T_1(x_13) <-> Q_13(x_13). forall x_13: ~P_10(x_13) or Q(x_13). forall x_13: P_10(x_13) or T_1(x_13). forall x_13: P_13(x_13) <-> Q_13(x_13). Can we infer forall x_13: P_10(x_13) or T_1(x_13) from them?
That is one of the premises. Therefore, the answer is yes.
