Two brothers worked together on a farm. One was married and had a large  51 . The other had no wife yet. Although they lived in different houses, they shared everything they got from their farm.
One day, the single brother said to himself, “It’s not  52  that we share all the rice. I’m  53  and I need less than my brother.” So, every night he took a bag of rice from his store-room and  54  across the field  55  their houses, putting it into his brother’s store-room.
At the same time, the married brother thought, “It’s not fair to share all the rice. I’m married and I have my wife and children to  56  me when I am  57 . However, my brother has no one to take care of his  58 .” So, each night he also took a bag of rice and put it into his brother’s store-room.
Several months passed by. They found  59  strange that their rice never became less. Then, one dark night the two brothers ran into each other. Slowly they began to understand what was happening. Their bags fell onto the ground and tears  60  their eyes at once.

For 99% of human history, people took their food from the world around them. They ate all that they could find, and then moved on. Then around 10,000 years ago, about 1% of human history, people learned to farm the land.
The kind of food we eat depends on which part of the world we live in, or which part of our country we live in. For example, in the south of China they eat rice, but in the north they eat noodles. In European countries near the sea, people eat a lot of fish. In central Europe, away from the sea, people don’t eat so much fish, but they eat more meat. For example, in Germany and Poland, there are hundreds of different kinds of sausages.
In North America, Australia, and Europe, people eat with knives and forks. In China, people eat with chopsticks. In parts of India and the Middle East, people use their fingers to pick up food.
Nowadays it is possible to transport food easily from one part of the world to another. We can eat whatever we like, at any time of the year. In Britain, bananas come from Africa; rice comes from India or the U.S.A.; strawberries come from Chile or Spain. Food is a very big business. But people in poor countries are still hungry while people in rich countries eat too much.
