Consider the following premises. For all x_13, x_13 is not a poet. There is at least one x_13 for which x_13 is a poet. For all x_13, x_13 is not a doctor or x_13 will go running. Can we infer the following from them? There is at least one x_13 for which x_13 is a sailor or x_13 will go running.
 From the fact that there is at least one x_13 for which x_13 is a poet we can infer that there is at least one x_13 for which x_13 is a poet or x_13 is a doctor. From the fact that there is at least one x_13 for which x_13 is a poet or x_13 is a doctor, and that for all x_13, x_13 is not a poet we can infer that there is at least one x_13 for which x_13 is a doctor. From the fact that there is at least one x_13 for which x_13 is a doctor we can infer that there is at least one x_13 for which x_13 is a doctor or x_13 is a sailor. Finally, from the fact that there is at least one x_13 for which x_13 is a doctor or x_13 is a sailor, and that for all x_13, x_13 is not a doctor or x_13 will go running we can infer that there is at least one x_13 for which x_13 is a sailor or x_13 will go running. Therefore, the answer is yes.
