Consider the following premises. There is at least one x_14 for which x_14 is a doctor. For all x_14, x_14 is a politician. For all x_14, if x_14 were a bartender, then x_14 is not playing tennis. For all x_14, if x_14 were a doctor, then x_14 is not a politician. Can we infer the following from them? For all x_14, x_14 is a bartender.
 From the fact that for all x_14, if x_14 were a doctor, then x_14 is not a politician, and that for all x_14, x_14 is a politician we can infer that for all x_14, x_14 is not a doctor. From the fact that there is at least one x_14 for which x_14 is a doctor we can infer that there is at least one x_14 for which x_14 is a doctor or x_14 will play tennis. From the fact that there is at least one x_14 for which x_14 is a doctor or x_14 will play tennis, and that for all x_14, x_14 is not a doctor we can infer that there is at least one x_14 for which x_14 will play tennis. Finally, from the fact that for all x_14, if x_14 were a bartender, then x_14 is not playing tennis, and that there is at least one x_14 for which x_14 will play tennis we can infer that there is at least one x_14 for which x_14 is not a bartender, which contradicts that For all x_14, x_14 is a bartender. Therefore, the answer is no.
