Consider the following premises. forall x_10: Q_10(x_10) -> W_2(x_10). forall x_10: W_2(x_10) -> Q_10(x_10). Q_10(a_5) -> r. Can we infer W_2(a_5) -> r from them?
 From forall x_10: W_2(x_10) -> Q_10(x_10), forall x_10: Q_10(x_10) -> W_2(x_10) we can infer forall x_10: W_2(x_10) <-> Q_10(x_10). From forall x_10: W_2(x_10) <-> Q_10(x_10) we can infer forall x_10: W_2(x_10) -> Q_10(x_10). From forall x_10: W_2(x_10) -> Q_10(x_10) we can infer W_2(a_5) -> Q_10(a_5). Finally, from W_2(a_5) -> Q_10(a_5), Q_10(a_5) -> r we can infer W_2(a_5) -> r. Therefore, the answer is yes.
