Consider the following premises. For all x_10, if x_10 were an astronaut, then x_10 is drinking water. For all x_10, x_10 will not make tea. Jessica is an astronaut or Sarah is a police officer. For all x_10, if x_10 drinks water, then x_10 is making tea. Can we infer the following from them? If we can, name the inference rule being used: Richard is not excited.
We cannot infer that from the premises. Therefore the answer is no.
