Consider the following premises. For all x, x is curious. There is at least one x for which if x listens to a song, then x is a taxi driver. For all x, if x were a taxi driver, then x is listening to a song. For all x, if x were curious, then x is listening to a song. Can we infer the following from them? There is at least one x for which x will listen to a song.
 From the fact that for all x, if x were a taxi driver, then x is listening to a song, and that there is at least one x for which if x listens to a song, then x is a taxi driver we can infer that there is at least one x for which x is a taxi driver if and only if x will listen to a song. From the fact that there is at least one x for which x is a taxi driver if and only if x will listen to a song we can infer that there is at least one x for which if x were a taxi driver, then x is listening to a song. From the fact that for all x, x is curious we can infer that for all x, x is curious or x is a taxi driver. Finally, from the fact that for all x, if x were curious, then x is listening to a song, that there is at least one x for which if x were a taxi driver, then x is listening to a song, and that for all x, x is curious or x is a taxi driver we can infer that there is at least one x for which x will listen to a song. Therefore, the answer is yes.
