[EX Q]: Article: When 18th-century scientists first came across Australia's platypus , they thought it was a trick. It is not surprising that the platypus made people confused. This funny-looking animal has feet and is a kind of warm-blooded mammal. While other mammals usually keep their blood at around 37 degrees, the platypus has a lower body temperature of 32 degrees. As to its appearance, the platypus'mouth is not really like ducks'at all; its mouth actually looks a bit soft. The platypus closes its eyes when swimming. It uses its mouth to pick up outside information made by the creatures underwater. Strangest of all, the platypus is a mammal that can lay eggs. And there is only one other kind of mammal that can lay eggs, the echidna of Australia. Both the platy-pus and the echidna lay soft-shelled eggs, and both feed their young with their own milk that comes out of their skin. These animals also walk in a way that is similar to crocodiles , with legs on the sides of their bodies rather than under them. Though pretty, in a special way, the platypus is actually one of the few mammals that are poisonous. A male platypus has knife-like bones on its back legs which have enough poison to kill a dog. The platypus has the honor of being one of the oldest mammals in the world. Until the early 20th century, it was hunted for its fur, but the situation has changed. Although the platypus is easily affected by pollution, it is not under any immediate threat.
Answer: It has a lower body temperature than other mammals.

[EX Q]: Article: For millions of people, the American dream of owning a home seems to be slipping out of reach. "Maybe young couples can no longer afford to buy a ready-made house as their parents did,'' says 40-year-old building instructor Pat Hennin. "But they can still have a home. Like their pioneer ancestors, they can build it themselves, and at less than half the cost of a ready-made house." The owner-builders came from every occupational group, although surprisingly few are professional building workers. Many _ with little or no experience. "I learned how to build my house from reading books," says John Brown, who built a six-room home for $25, 000 in High Falls, New Jersey. "If you have patience and the carpentry skill to make a bookcase, you can build a house." An astonishing 50 percent of these owner-builders hammer every nail, lay every pipe, and wire every switch with their own hands. The rest contract for some parts of the task. But even those who just act as contractors and finish the insides of their homes can save from 30 percent to 45 percent of what a ready-made home would cost. One survey revealed that 60 percent of owner-builders also design their homes. Many others buy commercial house plans for less than $100 or use plans available from the U. S. Department of Agriculture.
Answer: The American dream of owning a house.

[EX Q]: Article: Western teens share their top tunes Have you ever wondered what kind of music kids across the Pacific Ocean are listening to? Are they crazy about Britney Spears? Do they love the Backstreet Boys? Or do they dance to Eminem? Well, nearly 6,000 teens have taken part in a Teens & Music study, conducted by USA Weekend Magazine last autumn. And the results show what type of music is hot and what is not. It comes as no surprise that hip-hop and rap are the most popular types of music among American teenagers. They began in the mid-1970s, with young black kids in New York, taking music onto the streets. Hip-hop and rap are well-known for the breakdancing that goes with them. The word "rap" comes from a 1960s slang word for conversation. It is a rapid, slangy rhyme that is spoken rather than sung. Eminem is among the most popular rappers ever to hit the US. His first album "The Marshall Mathers LP" topped the American music chart in May 2000. Although about a third of teens in the US showed their support for him, almost as many said that his music was so offensive that they couldn't listen to it. Compared with Eminem, actor-rapper Will Smith is more of a star for the kids. He was awarded the Wannabe Award, on April 12 at Nickelodeon's 16th Annual Kids' Choice Awards. It is an award given to a celebrity whom kids most want to be. Pop music, such as Brittney Spears and the Backstreet Boys has always suited the tastes of the general public. It continues to enjoy support among teens and is second most popular after rap. Third is rock -- music with exciting dance beats and simple lyrics that speak loudly of social problems. The melodies are led by electric guitars. Rock became popular in the US in the early 1950s. American singer Elvis Presley and British group the Beatles became world-famous rock artists. The study also showed that jazz is least loved by American teens. It developed in the latter part of the 19th century from a mixture of African work songs and hymns . Jazz tends to be the type of music that people enjoy more as they get older.
Answer: Jazz.
