What can be inferred from the following premises in a single inference step (ignoring inferences that add new predicates or constants)? Name the inference rule being used: For all x_26, x_26 will drink water or x_26 is poor. For all x_26, if x_26 listens to a song, then x_26 is playing tennis. For all x_26, if x_26 were poor, then x_26 is listening to a song. For all x_26, if x_26 drinks water, then x_26 is listening to a song. William is making tea and it is raining.
William is making tea can be inferred via the simplification rule. It is raining can be inferred via the simplification rule. For all x_26, if x_26 were poor, then x_26 is playing tennis can be inferred via the universal transitivity rule. For all x_26, if x_26 drinks water, then x_26 is playing tennis can be inferred via the universal transitivity rule. For all x_26, x_26 will listen to a song can be inferred via the universal disjunction elimination rule.
