Consider the following premises. If Patricia were a musician, then Linda is working. If Linda works, then Michael is a politician. If Michael were a politician, then Linda is working. For all z, if z were a police officer, then z is a musician. Michael is a politician or Patricia is a police officer. Can we infer the following from them? Linda is not working.
 From the fact that for all z, if z were a police officer, then z is a musician we can infer that if Patricia were a police officer, then Patricia is a musician. From the fact that if Patricia were a police officer, then Patricia is a musician, and that if Patricia were a musician, then Linda is working we can infer that if Patricia were a police officer, then Linda is working. From the fact that if Michael were a politician, then Linda is working, and that if Linda works, then Michael is a politician we can infer that Michael is a politician if and only if Linda is working. From the fact that Michael is a politician if and only if Linda is working we can infer that if Michael were a politician, then Linda is working. Finally, from the fact that if Michael were a politician, then Linda is working, that if Patricia were a police officer, then Linda is working, and that Michael is a politician or Patricia is a police officer we can infer that Linda is working, which contradicts that Linda is not working. Therefore, the answer is no.
