Consider the following premises. forall x_13: T(x_13) -> W(x_13). forall x_13: T(x_13) or Q_13(x_13). forall x_13: Q_13(x_13) -> W(x_13). p. Can we infer p -> W(a_9) 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.
