Multiple choice

Who safeguards the shelter of bees?

Directions: Read the given passage and answer the following question:

Honeybees live in colonies with one queen running the whole hive. Worker honeybees are all females and are the only bees most people ever see flying around outside of the hive. They forage for food, build the honeycombs, and protect the hive. Honeybees are important pollinators for flowers, fruits, and vegetables. They live on stored honey and pollen all winter and cluster into a ball to conserve warmth. All honeybees are social and cooperative insects. The queen's job is simple - she lays the eggs that will spawn the hive's next generation of bees. There is usually a single queen in a hive. If the queen dies, workers will create a new queen by feeding one of the worker females a special food called "royal jelly." This elixir enables the worker to develop into a fertile queen.
