Consider the following premises. There is at least one x_6 for which x_6 is an artist. For all x_6, x_6 will go running or x_6 is an office clerk. For all x_6, x_6 will cook or x_6 will not go running. For all x_6, if x_6 were an office clerk, then x_6 is cooking. Can we infer the following from them? There is at least one x_6 for which x_6 will cook and x_6 is an artist.
 From the fact that for all x_6, x_6 will cook or x_6 will not go running we can infer that for all x_6, if x_6 goes running, then x_6 is cooking. From the fact that for all x_6, if x_6 goes running, then x_6 is cooking, that for all x_6, if x_6 were an office clerk, then x_6 is cooking, and that for all x_6, x_6 will go running or x_6 is an office clerk we can infer that for all x_6, x_6 will cook. Finally, from the fact that for all x_6, x_6 will cook, and that there is at least one x_6 for which x_6 is an artist we can infer that there is at least one x_6 for which x_6 will cook and x_6 is an artist. Therefore, the answer is yes.
