Consider the following premises. R_13(g_1) -> P_13(g_1). R_13(g_1). forall x_13: P_13(x_13) -> Q_13(x_13). forall x_13: Q_13(x_13) -> R_13(x_13). Can we infer ~q_2 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.
