Consider the following premises. For all x_6, x_6 will make tea or x_6 is not an artist. For all x_6, if x_6 makes tea, then x_6 is curious. There is at least one x_6 for which x_6 is not curious. Can we infer the following from them? There is at least one x_6 for which x_6 is not an artist.
 From the fact that for all x_6, if x_6 makes tea, then x_6 is curious, and that there is at least one x_6 for which x_6 is not curious we can infer that there is at least one x_6 for which x_6 will not make tea. From the fact that for all x_6, x_6 will make tea or x_6 is not an artist we can infer that for all x_6, if x_6 were an artist, then x_6 is making tea. Finally, from the fact that for all x_6, if x_6 were an artist, then x_6 is making tea, and that there is at least one x_6 for which x_6 will not make tea we can infer that there is at least one x_6 for which x_6 is not an artist. Therefore, the answer is yes.
