Name the inference rule being used: For all x_8, x_8 will drink water. For all x_8, if x_8 drinks water, then x_8 is a lawyer. For all x_8, x_8 will play tennis and x_8 will take a plane.
For all x_8, x_8 is a lawyer can be inferred via the universal modus ponens rule. For all x_8, x_8 will play tennis can be inferred via the universal simplification rule. For all x_8, x_8 will take a plane can be inferred via the universal simplification rule.
