Consider the following premises. For all x_11, x_11 is not a police officer or x_11 will take a plane. For all x_11, if x_11 were a sailor, then x_11 is drinking water. For all x_11, if x_11 plays tennis, then x_11 is a sailor. For all x_11, x_11 is a police officer or x_11 will play tennis. For all x_11, if x_11 takes a plane, then x_11 is drinking water. For all x_11, x_11 will make tea or x_11 will not drink water. Can we infer the following from them? If we can, name the inference rule being used: For all x_11, x_11 will make tea.
 From the fact that for all x_11, if x_11 plays tennis, then x_11 is a sailor, and that for all x_11, if x_11 were a sailor, then x_11 is drinking water we can infer that for all x_11, if x_11 plays tennis, then x_11 is drinking water via universal transitivity. From the fact that for all x_11, x_11 is a police officer or x_11 will play tennis, and that for all x_11, x_11 is not a police officer or x_11 will take a plane we can infer that for all x_11, x_11 will play tennis or x_11 will take a plane via universal resolution. From the fact that for all x_11, x_11 will make tea or x_11 will not drink water we can infer that for all x_11, if x_11 drinks water, then x_11 is making tea via universal rewriting. From the fact that for all x_11, if x_11 plays tennis, then x_11 is drinking water, that for all x_11, if x_11 takes a plane, then x_11 is drinking water, and that for all x_11, x_11 will play tennis or x_11 will take a plane we can infer that for all x_11, x_11 will drink water via universal disjunction elimination. Finally, from the fact that for all x_11, if x_11 drinks water, then x_11 is making tea, and that for all x_11, x_11 will drink water we can infer that for all x_11, x_11 will make tea via universal modus ponens. Therefore, the answer is yes.
