Consider the following premises. Q_13(f) or ~q_7. forall x_13: Q_13(x_13) -> P_13(x_13). forall x_13: P_13(x_13) -> Q_13(x_13). P_13(f) or q_7. Can we infer q 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.
