Consider the following premises. For all x_9, if x_9 plays squash, then x_9 is a poet. For all x_9, x_9 is a nurse or x_9 will play squash. For all x_9, x_9 is not a nurse or x_9 will drink water. For all x_9, if x_9 drinks water, then x_9 is a poet. For all x_9, x_9 will make tea. Can we infer the following from them? If we can, name the inference rule being used: Karen is not a poet.
 From the fact that for all x_9, x_9 is a nurse or x_9 will play squash, and that for all x_9, x_9 is not a nurse or x_9 will drink water we can infer that for all x_9, x_9 will play squash or x_9 will drink water via universal resolution. Finally, from the fact that for all x_9, if x_9 plays squash, then x_9 is a poet, that for all x_9, if x_9 drinks water, then x_9 is a poet, and that for all x_9, x_9 will play squash or x_9 will drink water we can infer that for all x_9, x_9 is a poet via universal disjunction elimination, which contradicts that Karen is not a poet. Therefore, the answer is no.
