Consider the following premises. For all x_8, if x_8 drinks water, then x_8 is curious. For all x_8, x_8 is a nurse or x_8 will play squash. For all x_8, if x_8 were a nurse, then x_8 is cooking. For all x_8, x_8 will not cook or x_8 is a taxi driver. For all x_8, if x_8 were a taxi driver, then x_8 is curious. For all x_8, if x_8 plays squash, then x_8 is cooking. Can we infer the following from them? If we can, name the inference rule being used: For all x_8, x_8 is curious.
 From the fact that for all x_8, if x_8 were a nurse, then x_8 is cooking, that for all x_8, if x_8 plays squash, then x_8 is cooking, and that for all x_8, x_8 is a nurse or x_8 will play squash we can infer that for all x_8, x_8 will cook via universal disjunction elimination. From the fact that for all x_8, x_8 will cook we can infer that for all x_8, x_8 will cook or x_8 will drink water via universal addition. From the fact that for all x_8, x_8 will cook or x_8 will drink water, and that for all x_8, x_8 will not cook or x_8 is a taxi driver we can infer that for all x_8, x_8 will drink water or x_8 is a taxi driver via universal resolution. Finally, from the fact that for all x_8, if x_8 drinks water, then x_8 is curious, that for all x_8, if x_8 were a taxi driver, then x_8 is curious, and that for all x_8, x_8 will drink water or x_8 is a taxi driver we can infer that for all x_8, x_8 is curious via universal disjunction elimination. Therefore, the answer is yes.
