Consider the following premises. There is at least one x_11 for which if x_11 were a politician, then x_11 is listening to a song. For all x_11, x_11 is a politician. For all x_11, x_11 will take a plane or x_11 is an artist. For all x_11, x_11 will not take a plane. Can we infer the following from them? For all x_11, either x_11 is an artist or x_11 will listen to a song are not true.
 From the fact that for all x_11, x_11 will take a plane or x_11 is an artist, and that for all x_11, x_11 will not take a plane we can infer that for all x_11, x_11 is an artist. From the fact that there is at least one x_11 for which if x_11 were a politician, then x_11 is listening to a song, and that for all x_11, x_11 is a politician we can infer that there is at least one x_11 for which x_11 will listen to a song. Finally, from the fact that for all x_11, x_11 is an artist, and that there is at least one x_11 for which x_11 will listen to a song we can infer that there is at least one x_11 for which x_11 is an artist and x_11 will listen to a song, which contradicts that For all x_11, either x_11 is an artist or x_11 will listen to a song are not true. Therefore, the answer is no.
