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 drives a car, then x_5 is reading a book. There is at least one x_5 for which if x_5 were poor, then x_5 is driving a car. For all x_5, if x_5 reads a book, then x_5 is taking a plane. For all x_5, x_5 will not take a plane.
For all x_5, x_5 will not read a book can be inferred via the universal modus tollens rule. For all x_5, if x_5 drives a car, then x_5 is taking a plane can be inferred via the universal transitivity rule. There is at least one x_5 for which if x_5 were poor, then x_5 is reading a book can be inferred via the existential transitivity rule.
