Question: Hans Christian Andersen put Denmark on the map of the world literature with his stories The Emperor's New Clothes,The Little MermaidandThe Ugly Duckling. Now Copenhagen, the country's capital, has become the center of the world political map, with 190 world leaders attending the climate talks there, not to mention thousands of reporters. Just how much do you know about the Scandinavian country? Denmark is famous for its design culture. At the heart of "Danish Design" is the idea that, as poet and designer Piet Hein puts it: "There is one art, not more, nor less, [and that is] to do all things with artlessness  ."  Danish design places equal emphasis on practicality and quality. From Lego toys to furniture, Danish products are known for their clean lines, simplicity and functionality. "Remove material where it's not needed. Keep things simple and functional and make them carefully," explained Hans J. Wegner, the first Danish designer to achieve worldwide fame: "The aim is not to create a work of art, but to produce a good chair." "The Danes have done a better job than most in promoting arts in Europe, considering their country's size and population, in the fields of architecture, sculpture and design," writes Helena Smith, reporter with British newspaper the Guardian.  The simplicity of Danish design may extend to the quality of life there. Some even claim that the Danes have the highest quality of life of any nation in the world.  Kate Vial, a 55-year-old American who has lived and worked in Denmark for more than 30 years, explaining why she chooses to live in Denmark rather than the US, told Germany's biggest news weekly Der Spiegel: "I just chose a simpler lifestyle, one where I could ride my bike all over and where I don't have to make a great living to survive." Which statement is true according to the passage? A) Danish design pays more attention to arts than its function. B) Danish products don't need much material. C) Danish people like to keep a simple life. D) Compared with other countries in Europe, Denmark does little in promoting arts.
Answer: C

Question: One potential problem with allowances is that children's responsible behavior can become about earning the allowance rather than the intrinsic value of their family responsibilities. For example, if you pay your children for taking out the rubbish, they see this chore   as a job that they should be rewarded for instead of a responsibility they must fulfill as part of the family. But giving children an allowance for weekly chores is not necessarily bad. You are rewarding them for fulfilling their family responsibilities, but it is not for a specific act. It is an appreciation of their commitment to your family values. You are also conveying another important message that their actions have consequences: if they do good things, good things happen. They also learn a lesson about the market economy, namely that work is rewarded. Allowances can also be used as punishment and to teach children lessons about family values. For example, if your children join a group of kids smashing   pumpkins on Halloween, a part of a reasonable punishment might be to require them to pay the families out of their allowance to replace the pumpkins. Thus, your children learn that bad behavior has financial consequences. Meanwhile, by relating the punishment to the misdeed, you ensure that your children see the connection and learn the value lesson. How much allowance should you pay your children? The precise amount depends on your family's financial situation, the cost of living and your children's needs. Children can start to earn a weekly allowance as early as 5 years of age. An increase of $ 1 per week for each year of your children's lives is realistic until they reach their mid-teens. When they begin to drive and date, you can calculate their expenses and establish a reasonable allowance that covers their needs. It can be inferred from the passage that  _  . A) the author doesn't want to give any tips on the allowance amount B) allowances given to children of different ages may vary C) children under 6 can't be given any allowance D) the allowance amount grows depending on the amount other children receive
