Consider the following premises. Sarah is listening to a song if and only if Linda is a janitor. If Linda were a janitor, then it is overcast. If it is overcast, then it is windy. Can we infer the following from them? If Sarah listens to a song, then it is windy.
 From the fact that Sarah is listening to a song if and only if Linda is a janitor we can infer that if Sarah listens to a song, then Linda is a janitor. From the fact that if Linda were a janitor, then it is overcast, and that if it is overcast, then it is windy we can infer that if Linda were a janitor, then it is windy. Finally, from the fact that if Sarah listens to a song, then Linda is a janitor, and that if Linda were a janitor, then it is windy we can infer that if Sarah listens to a song, then it is windy. Therefore, the answer is yes.
