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_5, if x_5 were curious, then x_5 is excited. For all x_5, x_5 will read a book and x_5 is a mechanic. For all x_5, x_5 is curious.
For all x_5, x_5 is excited can be inferred via the universal modus ponens rule. For all x_5, x_5 will read a book can be inferred via the universal simplification rule. For all x_5, x_5 is a mechanic can be inferred via the universal simplification rule.
