Question: Article: Columbus made four voyages to the west between 1492 and 1504 in his vain search for a sea route to Asia. The mystery of why he failed to find it haunted him and filled him with sadness. Wherever he went to Cuba, Puerto Rico, Jamaica, South America, Panama, down the coast of Central America--it was always the same story. Instead of golden palaces, there were grass huts and palm-leaf tents. Instead of silk-robed merchant princes, he found "Indians" who did not have so much as a shirt on their backs. When Columbus explored the West Indies in 1493,he heard tales of a fierce Indian tribe who literally devoured its defeated enemies after a battle. These people were called by many names in the area, including Calina, Canima, Carib, and Caniba. Columbus recorded the name of the American natives as Canibales in Spanish, a word which came to refer, within a few years, to any eater of human flesh. In the similar fashion, the word Caribbean, a title for the sea as well as for the region, came into English. At times Columbus knew that this new land was not China, not Japan, not the Spice Islands. He seemed to accept it as a part of the earth that the geographers of Europe had never heard of before. It was another world--and he called it exactly that--but Columbus also insisted until he died that land he had reached was an unknown part of Asia.

Question: Article: The audience starts to scream and young people all over Britain turn on their TVs. Yes, it's Top of the pops! Top of the pops is an amazing 45-year-old programme.

"We get lots of bands to perform live in the studio," says producer Chris Cowey. "That just doesn't happen on other shows" Chris starts the preparations for the programme over a week before it goes out.His first job is to decide which bands to have on the show. When the chart of the top twenty songs is produced on Sunday, Chris can start to book the bands Monday starts with Chris meeting his sound, lighting and camera workers. They listen to each song and plan the show. Tuesday is paperwork day. There are bookings to make sure of, letters to answer and lots of phone calls to make. The show is on Thursday. Bands arrive at the studio from 10 o'clock in the morning and start practicing. Tonight's presenter, Jo Whiley, practises too First the bands go to make up. Judy and Issy are the make-up artists. "We see the stars with no make-up on, looking terrible," says Issy. Then the bands go to the costume department where Marianne dresses the stars. Back in the studio things are happening. The audience is practising their dance moves! It takes over two hours to record the whole programme, then Chris edits it all night long. The final version is exactly 29 minutes long

Question: Article: Each year, about 10,000 to 100,000 animal species die off. They join the countless species that have gone extinct over the course of Earth's history - and extinction means forever. At least it used to. Scientists are now closing in on the ability to bring back extinct species. No, this doesn't mean the plot of Jurassic Park is going to become a reality. Researchers need DNA to bring back a species. DNA is the chemical that carries the structure for a living thing. Dinosaurs have been gone too long for any of their DNA to remain in fossils. But there's a very real chance that we will be able to bring back more recently extinct species. This could even include Ice Age animals like the woolly mammoth. In 2003, a team of Spanish and French scientists re-created the Pyrenean ibex, which had gone extinct three years earlier. The new animal didn't survive long, but scientific advances should improve the success rate. In January, Australian scientists announced that they were on their way to bringing back the gastric brooding frog. That we can bring species back doesn't mean that we should. There may be benefits to reviving a species. But there's no way to know how it will turn out. For example, would a passenger pigeon fit into its old habitat? Or might it crowd out existing species? Environmentalists worry that our ability to bring species back might cut down support for the hard work of traditional conservation. Why worry about preserving a wildlife habitat or fighting poachers if we know we can just make up for our mistakes? But those extinctions are our mistakes to correct, which may give us an obligation to do so. As businessman and environmentalist Stewart Brand recently said, "Humans have made a huge hole in nature. We have the ability now to repair some of that damage." We would do well to remember the lesson of Jurassic Park: Proceed with caution.
Answer: Because it is impossible to find DNA of dinosaurs in fossils.
