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