Consider the following premises. For all x_8, if x_8 were a bartender, then x_8 is a server. If Jessica were rich, then William is a server. For all x_8, if x_8 were a server, then x_8 is a bartender. Can we infer the following from them? If we can, name the inference rule being used: The fact that Jessica were rich does not imply that William is a bartender.
That contradicts the premises. Therefore the answer is no.
