Consider the following premises. For all x_8, if x_8 were a poet, then x_8 is a soldier. For all x_8, x_8 is a sailor. For all x_8, if x_8 were a sailor, then x_8 is rich. For all x_8, x_8 is a poet. Can we infer the following from them? If we can, name the inference rule being used: Jessica is not a soldier.
 From the fact that for all x_8, if x_8 were a sailor, then x_8 is rich, and that for all x_8, x_8 is a sailor we can infer that for all x_8, x_8 is rich via universal modus ponens. Finally, from the fact that for all x_8, if x_8 were a poet, then x_8 is a soldier, and that for all x_8, x_8 is a poet we can infer that for all x_8, x_8 is a soldier via universal modus ponens, which contradicts that Jessica is not a soldier. Therefore, the answer is no.
