Consider the following premises. For all x_6, x_6 is an electrician or x_6 will climb a mountain. There is at least one x_6 for which x_6 is an artist or x_6 will not climb a mountain. For all x_6, if x_6 plays a game, then x_6 is an artist. For all x_6, if x_6 were an electrician, then x_6 is playing a game. Can we infer the following from them? For all x_6, x_6 is not an artist.
 From the fact that for all x_6, if x_6 were an electrician, then x_6 is playing a game, and that for all x_6, if x_6 plays a game, then x_6 is an artist we can infer that for all x_6, if x_6 were an electrician, then x_6 is an artist. From the fact that there is at least one x_6 for which x_6 is an artist or x_6 will not climb a mountain we can infer that there is at least one x_6 for which if x_6 climbs a mountain, then x_6 is an artist. Finally, from the fact that for all x_6, if x_6 were an electrician, then x_6 is an artist, that there is at least one x_6 for which if x_6 climbs a mountain, then x_6 is an artist, and that for all x_6, x_6 is an electrician or x_6 will climb a mountain we can infer that there is at least one x_6 for which x_6 is an artist, which contradicts that For all x_6, x_6 is not an artist. Therefore, the answer is no.
