Consider the following premises. For all x_13, if x_13 were a musician, then x_13 is an artist. For all x_13, x_13 is not bored. For all x_13, x_13 is bored if and only if x_13 is a musician. For all x_13, if x_13 were an artist, then x_13 is a musician. For all x_13, x_13 will go running if and only if x_13 is an artist. Can we infer the following from them? There is at least one x_13 for which x_13 will go running.
 From the fact that for all x_13, if x_13 were a musician, then x_13 is an artist, and that for all x_13, if x_13 were an artist, then x_13 is a musician we can infer that for all x_13, x_13 is a musician if and only if x_13 is an artist. From the fact that for all x_13, x_13 is bored if and only if x_13 is a musician we can infer that for all x_13, if x_13 were a musician, then x_13 is bored. From the fact that for all x_13, if x_13 were a musician, then x_13 is bored, and that for all x_13, x_13 is not bored we can infer that for all x_13, x_13 is not a musician. From the fact that for all x_13, x_13 is a musician if and only if x_13 is an artist, and that for all x_13, x_13 is not a musician we can infer that for all x_13, x_13 is not an artist. Finally, from the fact that for all x_13, x_13 will go running if and only if x_13 is an artist, and that for all x_13, x_13 is not an artist we can infer that for all x_13, x_13 will not go running, which contradicts that There is at least one x_13 for which x_13 will go running. Therefore, the answer is no.
