Consider the following premises. For all x_13, x_13 is a taxi driver. For all x_13, x_13 is excited or x_13 is not a taxi driver. For all x_13, x_13 is excited or x_13 is not a nurse. Can we infer the following from them? Richard is not excited.
 From the fact that for all x_13, x_13 is a taxi driver we can infer that for all x_13, x_13 is a taxi driver or x_13 is a nurse. From the fact that for all x_13, x_13 is excited or x_13 is not a nurse we can infer that for all x_13, if x_13 were a nurse, then x_13 is excited. From the fact that for all x_13, x_13 is excited or x_13 is not a taxi driver we can infer that for all x_13, if x_13 were a taxi driver, then x_13 is excited. Finally, from the fact that for all x_13, if x_13 were a taxi driver, then x_13 is excited, that for all x_13, if x_13 were a nurse, then x_13 is excited, and that for all x_13, x_13 is a taxi driver or x_13 is a nurse we can infer that for all x_13, x_13 is excited, which contradicts that Richard is not excited. Therefore, the answer is no.
