Consider the following premises. For all y, y will play a game if and only if y will play tennis. For all y, y will play tennis or y is not an artist. For all y, y will not play a game. Can we infer the following from them? There is at least one y for which y is an artist.
 From the fact that for all y, y will play a game if and only if y will play tennis, and that for all y, y will not play a game we can infer that for all y, y will not play tennis. From the fact that for all y, y will play tennis or y is not an artist we can infer that for all y, if y were an artist, then y is playing tennis. Finally, from the fact that for all y, if y were an artist, then y is playing tennis, and that for all y, y will not play tennis we can infer that for all y, y is not an artist, which contradicts that There is at least one y for which y is an artist. Therefore, the answer is no.
