Consider the following premises. If Charles were an astronaut, then Barbara is not sleeping. If Susan plays tennis, then Barbara is sleeping. For all x_14, if x_14 plays squash, then x_14 is sleeping. Susan is playing tennis or Barbara is playing squash. Can we infer the following from them? If we can, name the inference rule being used: Charles is happy.
We cannot infer that from the premises. Therefore the answer is no.
