Consider the following premises. For all x_13, x_13 will make tea or x_13 will not listen to a song. There is at least one x_13 for which if x_13 climbs a mountain, then x_13 is a police officer. For all x_13, x_13 will listen to a song if and only if x_13 is a police officer. Can we infer the following from them? There is at least one x_13 for which if x_13 climbs a mountain, then x_13 is making tea.
 From the fact that for all x_13, x_13 will listen to a song if and only if x_13 is a police officer we can infer that for all x_13, if x_13 were a police officer, then x_13 is listening to a song. From the fact that for all x_13, x_13 will make tea or x_13 will not listen to a song we can infer that for all x_13, if x_13 listens to a song, then x_13 is making tea. From the fact that there is at least one x_13 for which if x_13 climbs a mountain, then x_13 is a police officer, and that for all x_13, if x_13 were a police officer, then x_13 is listening to a song we can infer that there is at least one x_13 for which if x_13 climbs a mountain, then x_13 is listening to a song. Finally, from the fact that there is at least one x_13 for which if x_13 climbs a mountain, then x_13 is listening to a song, and that for all x_13, if x_13 listens to a song, then x_13 is making tea we can infer that there is at least one x_13 for which if x_13 climbs a mountain, then x_13 is making tea. Therefore, the answer is yes.
