Consider the following premises. For all x_5, if x_5 were an artist, then x_5 is making tea. For all x_5, x_5 will drink water. For all x_5, x_5 is an artist or x_5 will listen to a song. For all x_5, if x_5 makes tea, then x_5 is writing a letter. For all x_5, if x_5 listens to a song, then x_5 is writing a letter. Can we infer the following from them? For all x_5, x_5 will drink water and x_5 will write a letter.
 From the fact that for all x_5, if x_5 were an artist, then x_5 is making tea, and that for all x_5, if x_5 makes tea, then x_5 is writing a letter we can infer that for all x_5, if x_5 were an artist, then x_5 is writing a letter. From the fact that for all x_5, if x_5 were an artist, then x_5 is writing a letter, that for all x_5, if x_5 listens to a song, then x_5 is writing a letter, and that for all x_5, x_5 is an artist or x_5 will listen to a song we can infer that for all x_5, x_5 will write a letter. Finally, from the fact that for all x_5, x_5 will drink water, and that for all x_5, x_5 will write a letter we can infer that for all x_5, x_5 will drink water and x_5 will write a letter. Therefore, the answer is yes.
