Consider the following premises. For all x_9, x_9 will play a game or x_9 is an artist. William is not curious. For all x_9, x_9 is not an artist or x_9 will climb a mountain. For all x_9, x_9 will not play a game. Can we infer the following from them? William is not climbing a mountain.
 From the fact that for all x_9, x_9 will play a game or x_9 is an artist, and that for all x_9, x_9 will not play a game we can infer that for all x_9, x_9 is an artist. From the fact that for all x_9, x_9 is an artist we can infer that for all x_9, x_9 is an artist or x_9 is curious. From the fact that for all x_9, x_9 is an artist or x_9 is curious, and that for all x_9, x_9 is not an artist or x_9 will climb a mountain we can infer that for all x_9, x_9 is curious or x_9 will climb a mountain. From the fact that for all x_9, x_9 is curious or x_9 will climb a mountain we can infer that William is curious or William is climbing a mountain. Finally, from the fact that William is curious or William is climbing a mountain, and that William is not curious we can infer that William is climbing a mountain, which contradicts that William is not climbing a mountain. Therefore, the answer is no.
