Consider the following premises. For all x_7, x_7 will not drink water. For all x_7, x_7 is rich or x_7 will cook. For all x_7, x_7 is not rich or x_7 will make tea. For all x_7, if x_7 cooks, then x_7 is drinking water. Can we infer the following from them? If we can, name the inference rule being used: James is not writing a letter.
