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, if x reads a book, then x is drinking water. For all x, x will not work. For all x, if x works, then x is reading a book. For all x, if x drinks water, then x is working.
For all x, x will not drink water can be inferred via the universal modus tollens rule. For all x, if x reads a book, then x is working can be inferred via the universal transitivity rule. For all x, if x works, then x is drinking water can be inferred via the universal transitivity rule. For all x, if x drinks water, then x is reading a book can be inferred via the universal transitivity rule.
