Bees can beat their wings 200 times each second.

Everyone knows that honeybees make honey, but how do they actually do it? Honeybees live in colonies, which means that they live with lots of other bees. Beehives, nests made of wax, are the places where they live and stow their honey. Honeybees drink nectar from flowers or other sweet deposits from plants or trees. The honey made by these bees is used to supply the colony with food during the cold winter when there arc no flowers to drink from. Thus, these bees not only consume the nectar...

Everyone knows that honeybees make honey, but how do they actually do it? Honeybees live in colonies, which means that they live with lots of other bees. Beehives, nests made of wax, are the places where they live and stow their honey.

Honeybees drink nectar from flowers or other sweet deposits from plants or trees. The honey made by these bees is used to supply the colony with food during the cold winter when there arc no flowers to drink from. Thus, these bees not only consume the nectar for nourishment but also bring it home. They have a special organ called a honey stomach which is used to carry the food to their colony.

When honeybees come back home, they regurgitate what they have put in their honey stomachs. Other honeybees in the hive come along and help them. They repeatedly eat and regurgitate many times until the product becomes somewhat digested. Next, the bees move the syrupy product into open honeycomb cells. Then they beat their wings to fan it to prevent fermentation. The fanning makes the water evaporate so that the product gets thick enough. Now it cannot easily be attacked by bacteria. Finally, it can be called honey. After this process, honeybees seal up the honeycomb cells with wax until they are hungry.

The most impressive part of this process is how seamlessly a bee colony works together. In a colony, there are female worker bees, male drones, and one queen bee. Although there are both male and females in the hive, the majority of the work is done by females. The female worker bees are in charge of taking care of the hive and creating honey. When they are young, they take care of feeding the young bee larvae. When they are older, they go out and bring nectar back to the hive, where they begin making honey. The male drones are responsible for fertilizing the eggs, but require little energy as they spend their time waiting around the hive. The single queen bee is responsible for the colony's survival. She is the only female that can lay eggs. The wonderful substance called honey would not exist without the bees' teamwork.

Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the questions from 36 to 42. 

Homing pigeons are placed in a training program from about the time they are twenty-eight days of age. They are taught to enter the loft through a trap and to exercise above and around the loft, and gradually they are taken away for short distances in wicker baskets and released. They are then expected to find their way home in the shortest possible time.        

 In their training flights or in actual races, the birds are taken to prearranged distant points and released to find their way back to their own lofts. Once the birds are liberated, their owners, who are standing by at the home lofts, anxiously watch the sky for the return of their entries. Since time is of the essence, the speed with which the birds can be induced to enter the loft trap may make the difference between gaining a win or a second place.         

The head of a homing pigeon is comparatively small, but its brain is one quarter larger than that of the ordinary pigeon. The homing pigeon is very intelligent and will persevere to the point of stubbornness; some have been known to fly a hundred miles off course to avoid a storm.   

Some homing pigeon experts claim that this bird is gifted with a form of built-in radar that helps it find its own loft after hours of flight, for hidden under the head feathers are two very sensitive ears, while the sharp, prominent eyes can see great distances in daytime.

Why do homing pigeons fly home? They are not unique in this inherent skill: it is found in most migratory birds, in bees, ants, toads, and even turtles, which have been known to travel hundreds of miles to return to their homes. But in the animal world, the homing pigeon alone can be trusted with its freedom and trained to carry out the missions that people demand

Why does the author mention bees, ants, toads, and turtles in the last paragraph?

A. To describe some unusual kinds of pets

B. To measure distances traveled by various animals

C. To compare their home-finding abilities with those of homing pigeons

D. To interest the reader in learning about other animals
