Article: For the Travel section, writers and editors selected special items to profile from a dozen cities. Brussels: Chocolate. Nearly half the chocolate consumed in the world is eaten in Europe, and Belgium--with average consumption of 14.99 pounds per person a year--certainly covers its fair share. While Brussels, the country's capital, is home to hundreds of chocolate makers, what makes a visit necessary is the rich heritage of traditional chocolate makers. Budapest: Paprika The job of preparing Hungarian paprika was once considered too dangerous for mothers to do. A woman who touched her children upon returning from work risked burning them, so only the elderly and unmarried were allowed the delicate task of separating the skin from the flesh. But by the early 20thcentury, sweeter varieties and a machine turned paprika into a common feature of all Hungarian cuisine. Lisbon: Tiles Is there a bluer country than Portugal? The blue sky and Atlantic Ocean embrace the land. The blue moods of Fado, the dark folk music, form the national soundtrack. And all across Portugal, the typically--blue designs of azulejos--ceramic tiles--are spread across churches, castles, palaces, university halls, parks. The result is a beautiful land of Christian saints, Portuguese kings, historical glories, aristocrats at leisure, seascapes and so on. Madrid: Guitars Walking into one the Madrid's storied guitar makers' workshops can feel like stepping into the past. Curly wood shavings, from the palest pine to ebony, fall onto the floor as artisans turn some humble wood into works of art. It's painstaking work--all done by hand--with classical guitar models and the methods of making them changing little over the last century.
Answer: The hot level of Hungarian peppers.
answer:
What does the job of preparing Hungarian paprika suggest?

Article: For a long time people have believed that high self-esteem is the key to success. However, new research shows that focusing just on building self-esteem may not be helpful. In some cases, having high self-esteem can bring bad results if it makes you less likeable or more upset when you fail at something. "Forget about self-esteem," says one of the psychologists involved in the new research. "It's not the most important thing." This idea may sound a bit strange to you because studies also show that people with high self-esteem are less likely to be anxious, shy, or lonely than those with low self-esteem. In short, to feel good does you good. But, after reviewing about 18,000 studies on self-esteem, Roy Baumeister, a psychologist at Florida State University, has found that building up your self-esteem will not necessarily make you a better person. He believes that violent and evil people often have the highest self-esteem of all. He also said, "There's no evidence that kids with high self-esteem do better in school." All types of people have problems. "People with high self-esteem can have big egos that can make them less likeable to their peers," said Kathleen Vohs, a psychology professor at Columbia University. "People with high self-esteem tend to think more of themselves," Vohs says. People with low self-esteem are more likely to rely on their friends when they need help. Researchers say it is best to listen to and support other people. Find positive ways to contribute to society. If you fail at something, try to learn from the experience. The best therapy , as they suggest, is to recognize your faults, accept yourself, understand your weaknesses and then do something about them.
Answer: New research shows that high self-esteem may not be helpful.

Article: Do you know what a castle is? A castle is a building special to Europe. Castles were built in the Middle Ages by king and other powerful people who live in. Castles were used by people to protect themselves from their enemies. They are big buildings made form stone and wood. Today there are still castles all over Europe. Some are in ruins. But some built later are still in good repair and used even today. One example is Windsor Castle, which is a home to the British queen. It is in the country or Berkshire, not far from London. Castles have walls around them. In the old days, soldiers would stand on the walls to guard the people in the castle. If enemies came they would shoot arrows and throw stones at them. Castles also had moats. A moat is a river around the wall that makes it difficult for enemies to get in. It could be either dry or filled with water. Other people from younger countries love European castles. In the US there are rich people who have brought broken parts of castles to their country and rebuilt them. And some people build "replica" castles---modern copies of Castle. You probably know the Disneyland Castle in California, US. But did you know it is based on a famous castle in Germany built by King Ludwig IIof Bavaria?
