Consider the following premises. For all x_13, if x_13 plays tennis, then x_13 is running. For all x_13, x_13 is rich or x_13 will play tennis. For all x_5, if x_5 goes running, then x_5 is sleeping. For all x_13, x_13 is rich if and only if x_13 will go running. Can we infer the following from them? If we can, name the inference rule being used: Richard is not a server.
We cannot infer that from the premises. Therefore the answer is no.
