They even stand at the opening and fan their wings to cool the hive. Worker bees will attack anything--even people--to keep their hive safe. Another kind of bee is the drone . Drones are male bees, and their job is to fly with the queen bee and mate with her. After the queen mates, the worker bees drive the drones away. The drones then starve to death. The third kind of bee is the queen. Each hive needs only one queen, and her job is laying eggs. She can lay as many as 2, 000 eggs a day. Question: The drone is driven away when its job is finished, because _ . - it attacked the workers - it is no longer needed in the hive - the queen bee has died - it ate the queen bee
