Consider the following premises. Karen is writing a letter. For all x_14, if x_14 writes a letter, then x_14 is listening to a song. If Karen listens to a song, then Michael is drinking water. Can we infer the following from them? If we can, name the inference rule being used: For all x_14, if x_14 writes a letter, then x_14 is listening to a song.
That is one of the premises. Therefore, the answer is yes.
