Consider the following premises. For all x_11, if x_11 plays squash, then x_11 is an electrician. For all x_11, if x_11 climbs a mountain, then x_11 is cooking. For all x_11, x_11 will play squash or x_11 will climb a mountain. There is at least one x_11 for which if x_11 were an electrician, then x_11 is cooking. Can we infer the following from them? If we can, name the inference rule being used: For all x_11, neither x_11 will cook nor x_11 will make tea.
That contradicts the premises. Therefore the answer is no.
