Consider the following premises. There is at least one x_13 for which x_13 is a police officer and x_13 is a doctor. For all x_13, if x_13 were happy, then x_13 is cooking. For all x_13, if x_13 were a police officer, then x_13 is sleeping. For all x_13, if x_13 cooks, then x_13 is sleeping. Can we infer the following from them? For all x_13, x_13 will not sleep.
 From the fact that there is at least one x_13 for which x_13 is a police officer and x_13 is a doctor we can infer that there is at least one x_13 for which x_13 is a police officer. From the fact that for all x_13, if x_13 were happy, then x_13 is cooking, and that for all x_13, if x_13 cooks, then x_13 is sleeping we can infer that for all x_13, if x_13 were happy, then x_13 is sleeping. From the fact that there is at least one x_13 for which x_13 is a police officer we can infer that there is at least one x_13 for which x_13 is a police officer or x_13 is happy. Finally, from the fact that for all x_13, if x_13 were a police officer, then x_13 is sleeping, that for all x_13, if x_13 were happy, then x_13 is sleeping, and that there is at least one x_13 for which x_13 is a police officer or x_13 is happy we can infer that there is at least one x_13 for which x_13 will sleep, which contradicts that For all x_13, x_13 will not sleep. Therefore, the answer is no.
