Consider the following premises. For all x_8, x_8 will not drink water. For all x_8, x_8 will take a plane if and only if x_8 will drink water. For all x_8, x_8 will listen to a song or x_8 is a poet. For all x_8, if x_8 listens to a song, then x_8 is taking a plane. Can we infer the following from them? There is at least one x_8 for which x_8 is not a poet.
 From the fact that for all x_8, x_8 will take a plane if and only if x_8 will drink water, and that for all x_8, x_8 will not drink water we can infer that for all x_8, x_8 will not take a plane. From the fact that for all x_8, if x_8 listens to a song, then x_8 is taking a plane, and that for all x_8, x_8 will not take a plane we can infer that for all x_8, x_8 will not listen to a song. Finally, from the fact that for all x_8, x_8 will listen to a song or x_8 is a poet, and that for all x_8, x_8 will not listen to a song we can infer that for all x_8, x_8 is a poet, which contradicts that There is at least one x_8 for which x_8 is not a poet. Therefore, the answer is no.
