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_11, x_11 will take a plane or x_11 is an astronaut. For all x_11, if x_11 cooks, then x_11 is a police officer. For all x_11, x_11 will play squash or x_11 is not a police officer. For all x_11, x_11 will not take a plane or x_11 is curious. For all x_11, if x_11 were curious, then x_11 is a police officer. For all x_11, if x_11 were an astronaut, then x_11 is cooking.
For all x_11, if x_11 were an astronaut, then x_11 is a police officer can be inferred via the universal transitivity rule. For all x_11, x_11 is an astronaut or x_11 is curious can be inferred via the universal resolution rule. For all x_11, if x_11 were a police officer, then x_11 is playing squash can be inferred via the universal rewriting rule.
