Have you seen Jurassic Park? In this film, scientists use DNA kept for tens of millions of years to clone dinosaurs. They find trouble, however, when they realize that the cloned creatures are smarter and more dangerous than expected. That's nothing more than a fiction. But could we really clone endangered animals? To date, the most successful attempt to do so was the cloning of a gaur, a rare ox-like animal from southeast Asia. Scientists used a cow to bring the cloned baby gaur, named Noah. Two days after birth, however, Noah died from a common bacterial infection. Other endangered species that may be cloned include the African bongo antelope  , the Sumatran tiger, the cheetah  , and the giant panda. Next, could we really clone extinct animals? In theory? Yes. To do this, you need a well-kept source of DNA from the extinct animals such as wool mammoth  , Tasmanian tiger, or even dinosaur, and a closely related species, still living, which could serve as a surrogate mother. In reality? Probably not. On the one hand, it's not likely that extinct animals' DNA could survive undamaged for such a long time. Cloning extinct animals as wool mammoth, Tasmanian tiger, or dinosaur is much more difficult due to the lack of properly well-preserved DNA. On the other hand, for example, a gaur can have a cow as _ , definitely not a monkey. But what about an extinct animal as unique as the panda? What species could possibly serve as a surrogate mother? Cloning presents many exciting possibilities. However, even if extinct animals are brought back, they could not survive in today's world. Not only do most extinct animals have no habitat to live in, but the other plants and animals they depended on for food may also be gone as well. In the author's opinion, it is possible that   _  . A) some extinct species may be cloned, but not survive B) extinct species may be cloned and easily survive C) a gaur can have a monkey as a surrogate mother D) all the extinct species may be cloned

Music probably isn't the main reason for where you choose to eat something, but restaurant owners put a lot of thought into what they play. In a recent article about music's role in restaurant design, author Mark Brandau details the different ways sound influences   sales. Here are a few "notes" to keep in mind the next time you need to pick a restaurant: It's someone's job to design playlists. Restaurant owners hire   experts to build music playlists for different times of the day. A restaurant owner says, "Lively songs encourage quick dining and faster table turns at meal time." What you hear at lunch won't be what you hear at dinner. And what you hear after dinner will be something totally different. If a restaurant wants to increase late-night sales, music is very important to creating the right atmosphere. Music builds brands  . Nick Vojnovic, president of Little Greek, had been in the business for 20 years. He began to realize how important music is to the restaurant experience after listening to a manager from The Cheesecake Factory speak about using music to develop brand identity. Where have you heard that before? Restaurants may be using the same music providers. Ambiance Radio provides playlists for Little Greek in Florida, and also Schlotzsky's and Union Square Cafe in New York City. Vojnovic, who started his business at Chili's, pointed out that years ago, background music was changed only once per quarter. Music helps restaurants choose diners. Brandau explains that some restaurants would like to turn up the music, not to bother   certain groups of customers, but to stay true to their main diners. If college kids are a restaurant's main diners, the restaurant will surely play music that makes older people feel uninvited. We can learn from the passage that   _  . A) the restaurant owners often play music they like B) Mark Brandau is an expert at designing restaurants C) some restaurants use music to influence people who eat there D) at meal time restaurants should play slow music to help diners relax

Even plants can run a fever, especially when they're under attack by insects or disease. But unlike human, plants can have their temperature taken from 3,000 feet away--straight up. A decade ago, adopting the infrared scanning technology developed for military purposes and other satellites, physicist Stephen Paley came up with a quick way to take the temperature of crops to determine which ones are under stress. The goal was to let farmers precisely target pesticide spraying rather than rain poison on a whole field, which invariably includes plants that don't have pest problems. Even better, Paley's Remote Scanning Services Company could detect crop problems before they became visible to the eye. Mounted on a plane flown at 3,000 feet at night, an infrared scanner measured the heat emitted by crops. The data were transformed into a colourcoded map showing where plants were running "fevers". Farmers could then spotspray, using 50 to 70 percent less pesticide than they otherwise would. The bad news is that Paley's company closed down in 1984, after only three years. Farmers resisted the new technology and longterm backers were hard to find. But with the renewed concern about pesticides on produce, and refinements in infrared scanning, Paley hopes to get back into operation. Agriculture experts have no doubt the technology works. "This technique can be used on 75 percent of agricultural land in the United States, " says George Oerther of Texas A & M. Ray Jackson, who recently retired from the Department of Agriculture, thinks remote infrared crop scanning could be adopted by the end of the decade. But only if Paley finds the financial backing which he failed to obtain 10 years ago. The application of infrared scanning technology to agriculture met with some difficulties--  _  . A) its high cost B) the lack of official support C) the lack of financial support D) its failure to help increase production
