Consider the following premises. There is at least one x_11 for which if x_11 were poor, then x_11 is not a musician. For all x_11, x_11 will go running if and only if x_11 is a musician. For all x_11, x_11 will go running or x_11 will work. For all x_11, if x_11 works, then x_11 is climbing a mountain. For all x_11, if x_11 climbs a mountain, then x_11 is a musician. Can we infer the following from them? For all x_11, x_11 is poor.
 From the fact that for all x_11, x_11 will go running if and only if x_11 is a musician we can infer that for all x_11, if x_11 goes running, then x_11 is a musician. From the fact that for all x_11, if x_11 works, then x_11 is climbing a mountain, and that for all x_11, if x_11 climbs a mountain, then x_11 is a musician we can infer that for all x_11, if x_11 works, then x_11 is a musician. From the fact that for all x_11, if x_11 goes running, then x_11 is a musician, that for all x_11, if x_11 works, then x_11 is a musician, and that for all x_11, x_11 will go running or x_11 will work we can infer that for all x_11, x_11 is a musician. Finally, from the fact that there is at least one x_11 for which if x_11 were poor, then x_11 is not a musician, and that for all x_11, x_11 is a musician we can infer that there is at least one x_11 for which x_11 is not poor, which contradicts that For all x_11, x_11 is poor. Therefore, the answer is no.
