Consider the following premises. For all y_3, y_3 is not a bartender. If Sarah were a bartender, then Linda is curious. If Linda were curious, then Sarah is a bartender. Can we infer the following from them? Linda is curious.
 From the fact that for all y_3, y_3 is not a bartender we can infer that Sarah is not a bartender. From the fact that if Linda were curious, then Sarah is a bartender, and that if Sarah were a bartender, then Linda is curious we can infer that Linda is curious if and only if Sarah is a bartender. Finally, from the fact that Linda is curious if and only if Sarah is a bartender, and that Sarah is not a bartender we can infer that Linda is not curious, which contradicts that Linda is curious. Therefore, the answer is no.
