Consider the following premises. For all z, z is not an artist. For all z, z is an artist or z will not work. There is at least one z for which if z were an artist, then z is a sailor. For all z, if z were a sailor, then z is working. Can we infer the following from them? For all z, z will work.
 From the fact that there is at least one z for which if z were an artist, then z is a sailor, and that for all z, if z were a sailor, then z is working we can infer that there is at least one z for which if z were an artist, then z is working. From the fact that for all z, z is an artist or z will not work we can infer that for all z, if z works, then z is an artist. From the fact that there is at least one z for which if z were an artist, then z is working, and that for all z, if z works, then z is an artist we can infer that there is at least one z for which z is an artist if and only if z will work. Finally, from the fact that there is at least one z for which z is an artist if and only if z will work, and that for all z, z is not an artist we can infer that there is at least one z for which z will not work, which contradicts that For all z, z will work. Therefore, the answer is no.
