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_10, if x_10 were fast, then x_10 is running. For all x_10, if x_10 were a sailor, then x_10 is not drinking water. For all x_10, x_10 will listen to a song. For all x_10, x_10 will drink water. For all x_10, x_10 is a sailor or x_10 is fast.
For all x_10, x_10 is not a sailor can be inferred via the universal modus tollens rule. For all x_10, x_10 will listen to a song and x_10 will drink water can be inferred via the universal conjunction rule. For all x_10, x_10 will drink water and x_10 will listen to a song can be inferred via the universal conjunction rule.
