Consider the following premises. For all x_13, x_13 is a musician or x_13 is rich. For all x_13, if x_13 takes a plane, then x_13 is a carpenter. For all x_13, x_13 is not a musician. For all x_13, x_13 is poor if and only if x_13 is a carpenter. There is at least one x_13 for which if x_13 were rich, then x_13 is taking a plane. Can we infer the following from them? For all x_13, x_13 is not a carpenter.
 From the fact that for all x_13, x_13 is a musician or x_13 is rich, and that for all x_13, x_13 is not a musician we can infer that for all x_13, x_13 is rich. From the fact that there is at least one x_13 for which if x_13 were rich, then x_13 is taking a plane, and that for all x_13, if x_13 takes a plane, then x_13 is a carpenter we can infer that there is at least one x_13 for which if x_13 were rich, then x_13 is a carpenter. From the fact that for all x_13, x_13 is rich we can infer that for all x_13, x_13 is rich or x_13 is poor. From the fact that for all x_13, x_13 is poor if and only if x_13 is a carpenter we can infer that for all x_13, if x_13 were poor, then x_13 is a carpenter. Finally, from the fact that there is at least one x_13 for which if x_13 were rich, then x_13 is a carpenter, that for all x_13, if x_13 were poor, then x_13 is a carpenter, and that for all x_13, x_13 is rich or x_13 is poor we can infer that there is at least one x_13 for which x_13 is a carpenter, which contradicts that For all x_13, x_13 is not a carpenter. Therefore, the answer is no.
