Consider the following premises. For all x_5, x_5 is a lawyer or x_5 will listen to a song. For all x_5, if x_5 were a lawyer, then x_5 is a taxi driver. For all x_5, x_5 is not a taxi driver. For all x_5, if x_5 were a taxi driver, then x_5 is a lawyer. Can we infer the following from them? There is at least one x_5 for which x_5 will not listen to a song.
 From the fact that for all x_5, if x_5 were a lawyer, then x_5 is a taxi driver, and that for all x_5, if x_5 were a taxi driver, then x_5 is a lawyer we can infer that for all x_5, x_5 is a lawyer if and only if x_5 is a taxi driver. From the fact that for all x_5, x_5 is a lawyer if and only if x_5 is a taxi driver, and that for all x_5, x_5 is not a taxi driver we can infer that for all x_5, x_5 is not a lawyer. Finally, from the fact that for all x_5, x_5 is a lawyer or x_5 will listen to a song, and that for all x_5, x_5 is not a lawyer we can infer that for all x_5, x_5 will listen to a song, which contradicts that There is at least one x_5 for which x_5 will not listen to a song. Therefore, the answer is no.
