Consider the following premises. Karen is a server if and only if Sarah is making tea. For all x_15, if x_15 makes tea, then x_15 is playing a game. If Mary listens to a song, then Karen is a server. Sarah is not playing a game. Can we infer the following from them? Mary is listening to a song.
 From the fact that for all x_15, if x_15 makes tea, then x_15 is playing a game we can infer that if Sarah makes tea, then Sarah is playing a game. From the fact that if Sarah makes tea, then Sarah is playing a game, and that Sarah is not playing a game we can infer that Sarah is not making tea. From the fact that Karen is a server if and only if Sarah is making tea, and that Sarah is not making tea we can infer that Karen is not a server. Finally, from the fact that if Mary listens to a song, then Karen is a server, and that Karen is not a server we can infer that Mary is not listening to a song, which contradicts that Mary is listening to a song. Therefore, the answer is no.
