Consider the following premises. Linda is a bartender and Barbara is cooking. If Robert works, then Linda is not a bartender. If Robert doesn't work, then Karen is a police officer. Can we infer the following from them? Karen is not a police officer.
 From the fact that Linda is a bartender and Barbara is cooking we can infer that Linda is a bartender. From the fact that if Robert works, then Linda is not a bartender, and that Linda is a bartender we can infer that Robert is not working. Finally, from the fact that if Robert doesn't work, then Karen is a police officer, and that Robert is not working we can infer that Karen is a police officer, which contradicts that Karen is not a police officer. Therefore, the answer is no.
