PROBLEM: Article: The story happened during the Second World War. An old man lived in a small town of Germany. He had three sons and they all worked in the same factory where he had worked. After the war had begun, his sons were all made to join the army one after another and they all died in the fights. The old man was very sad. He didn't have enough food and was often hungry. And nobody helped him and he didn't know how to go on living. It was a very cold winter night. The old man couldn't go to sleep. He had been hungry for two days and it was so cold in his room that ice could be seen. He had to get up and began to run in the room until he lay down on the floor. The next morning he had to beg from door to door. He had been to a lot of cities and knew a lot. Once he came to a village, but the villagers were all poor and couldn't give him anything. He was too hungry to go to another village. He thought hard and found a way. He came to a police station and called out, "Hitler is a foolish pig!" Out came an old policeman at once. He took the old man into a room, gave him some bread and a cup of tea. Then he said, "Don't say so in our village, sir!" "I'm sorry, sir," said the old man. "I don't know it's Hitler's hometown." "No, no, sir," the policeman said in a hurry. "It's pigs' hometown!"

PROBLEM: Article: If you give something to someone for free, will that person value it and use it? Development experts have debated this question for decades. Some think the act of paying causes people to value something and use it more. Selling necessary health treatments, others argue, may deny them to the people who need them the most. Consider, for example, chemically treated bed nets, which kill mosquitoes anti protect people against malaria while they are sleeping. William Easterly, an economist at New York University, believes this is one example of development having gone wrong. In a recent book, Professor Easterly suggests bed nets given free in Africa are often used for the wrong purpose. Yet, the World Health Organization (WHO) recommends bed nets be given out free and used by whole communities. The success of a large free bed net campaign in Kenya led the WHO to announce this recommendation This debate will likely influence social programs in the developing world. Many non-governmental organizations support the creation of self-supporting programs in poor countries. Goods and services are sold for a price to help these programs survive. According to Rachel Glenerster, who runs a research lab doing development and poverty studies at the Massachusetts Institute of Technology, her several studies have proven that small price changes have a big influence on the number of people who use a product. A price change will reduce the total amount of use of the product as well, she says. She has also found no evidence that the very act of paying for something changes how people use it. As for a particular product among special populations, some development experts argue that pricing is useful. When it comes to bed nets, Miss Glenerster says research shows no evidence of this. People are just as likely to use a bed net whether they paid for it or not.
