Read the following passage.
Harriet quietly slipped her key into the front door lock and turned it very carefully. It was a sunny afternoon, and as she eased the door open, she thought she heard a neighbor walk by. She stopped her movements, startled, but it was only her imagination. She slowly pushed open the heavy door, careful not to make the hinges squeal. She slipped through the front door, desperately trying to remember which floor plank creaked the loudest. “It’s the one on the left,” she remembered with relief, and carefully placed her foot on the plank to the right.
