Consider the following premises. For all x_5, if x_5 makes tea, then x_5 is not an office clerk. For all x_5, if x_5 were an artist, then x_5 is making tea. For all x_5, x_5 is an office clerk. For all x_5, if x_5 makes tea, then x_5 is an artist. Can we infer the following from them? There is at least one x_5 for which x_5 is an artist.
 From the fact that for all x_5, if x_5 makes tea, then x_5 is an artist, and that for all x_5, if x_5 were an artist, then x_5 is making tea we can infer that for all x_5, x_5 will make tea if and only if x_5 is an artist. From the fact that for all x_5, if x_5 makes tea, then x_5 is not an office clerk, and that for all x_5, x_5 is an office clerk we can infer that for all x_5, x_5 will not make tea. Finally, from the fact that for all x_5, x_5 will make tea if and only if x_5 is an artist, and that for all x_5, x_5 will not make tea we can infer that for all x_5, x_5 is not an artist, which contradicts that There is at least one x_5 for which x_5 is an artist. Therefore, the answer is no.
