Consider the following premises. forall x_16: P_16(x_16) or Q_16(x_16). forall x_16: R_16(x_16) -> R_2(x_16). exists x_16: ~P_16(x_16) or R_16(x_16). forall x_16: Q_16(x_16) <-> R_2(x_16). Can we infer exists x_16: ~P_16(x_16) or R_16(x_16) from them?
That is one of the premises. Therefore, the answer is yes.
