Consider the following premises. For all x_11, x_11 is fast. There is at least one x_11 for which x_11 is an artist. For all x_11, x_11 is poor. Can we infer the following from them? For all x_11, either x_11 is poor or x_11 is fast are not true.
 From the fact that for all x_11, x_11 is fast, and that there is at least one x_11 for which x_11 is an artist we can infer that there is at least one x_11 for which x_11 is fast and x_11 is an artist. From the fact that there is at least one x_11 for which x_11 is fast and x_11 is an artist we can infer that there is at least one x_11 for which x_11 is fast. Finally, from the fact that for all x_11, x_11 is poor, and that there is at least one x_11 for which x_11 is fast we can infer that there is at least one x_11 for which x_11 is poor and x_11 is fast, which contradicts that For all x_11, either x_11 is poor or x_11 is fast are not true. Therefore, the answer is no.
