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 y, if y plays squash, then y is driving a car. For all y, if y were poor, then y is driving a car. For all y, if y listens to a song, then y is not driving a car. For all y, y is poor or y will play squash.
For all y, y will drive a car can be inferred via the universal disjunction elimination rule.
