Consider the following premises. forall x_16: P_16(x_16) -> R_16(x_16). forall x_16: P_16(x_16) or Q_16(x_16). forall x_16: Q_12(x_16). forall x_16: Q_16(x_16) -> R_16(x_16). Can we infer ~w from them? If possible, name the inference rules being used at each step.
We cannot infer that from the premises. Therefore the answer is no.
