Consider the following premises. For all x_7, x_7 will climb a mountain and x_7 is a janitor. For all x_7, if x_7 climbs a mountain, then x_7 is a server. For all x_7, x_7 is not a server. Can we infer the following from them? If we can, name the inference rule being used: For all x_7, x_7 will climb a mountain and x_7 is a janitor.
That is one of the premises. Therefore, the answer is yes.
