Consider the following premises. There is at least one x_4 for which x_4 will not drive a car or x_4 is an office clerk. For all x_4, if x_4 were a writer, then x_4 is an artist. For all x_4, x_4 will drive a car or x_4 is a writer. For all x_4, x_4 is not an artist. Can we infer the following from them? For all x_4, x_4 is not an office clerk.
 From the fact that for all x_4, if x_4 were a writer, then x_4 is an artist, and that for all x_4, x_4 is not an artist we can infer that for all x_4, x_4 is not a writer. From the fact that for all x_4, x_4 will drive a car or x_4 is a writer, and that there is at least one x_4 for which x_4 will not drive a car or x_4 is an office clerk we can infer that there is at least one x_4 for which x_4 is a writer or x_4 is an office clerk. Finally, from the fact that there is at least one x_4 for which x_4 is a writer or x_4 is an office clerk, and that for all x_4, x_4 is not a writer we can infer that there is at least one x_4 for which x_4 is an office clerk, which contradicts that For all x_4, x_4 is not an office clerk. Therefore, the answer is no.
