69.(A) making (B) make (C) has made (D) was made IV. Reading Comprehension Article A Ant colonies are divided into queens, males, and workers. The job of the queen is to lay eggs. The males generally do not work, but receive food from the workers until it is time for them to mate. They die almost immediately after mating. Workers are sterile females. Instead of reproducing, they perform a variety of roles that benefit the colony. They forage for food, defend the colony from attack, construct the nest, and take care of the queen. Only a small percentage of worker ants are foragers. They face greater risks as they are constantly exposed to external dangers from predators while hunting for food.
