TEXT D Robert Congel, a commercial real-estate developer who lives in upstate New York, has a plan to "change the world." Convinced that it will "produce more benefit for humanity than any one thing that private enterprise has ever done," he is raising $20 billion to make it happen. That’ s 12 times the yearly budget of the United Nations and more than 25 times Congel’ s own net worth. What Congel has in mind is an outsize and extremely unusual mega-mall. Destiny U.S.A., the retail-and entertainment complex he is building in upstate New York, aspires to be not only the biggest man-made structure on the planet but also the most environmentally friendly. Equal parts Disney World, Las Vegas, Bell Laboratories and Mall of America -- with a splash of Walden Pond -- the "retail city" will include the usual shops and restaurants as well as an extensive research facility for testing advanced technologies and a 200-acre recreational biosphere complete with spring-like temperatures and an artificial river for kayaking. After a false start in 2002, countless changes of plan and a storm of local opposition, Congel is finally breaking ground again, with a projected completion date of 2009. Later this month, bulldozers powered by biodiesel are scheduled to begin leveling the site, a rehabilitated brownfield in Syracuse, Congel’ s hometown. Whether Congel’ s firm, the Pyramid Companies, can maintain the cash flow and political support needed to complete the project is a subject of much local debate. Also disputed are Congel’ s goals of creating 200,000 jobs regionally and making Destiny nothing less than "the No. l tourist destination in America." More mind-boggling than the sheer scope of Destiny is its agenda. Congel emphasizes that renewable energy alone will power the mall, with its 1,000 shops and restaurants, 80,000 hotel rooms, 40,000-seat arena and Broadway-style theaters. As a result, Congel says, Destiny will jump-start renewable-energy markets nationwide with its investments in solar, ,,wind, fuel cells and other alternative-energy sources. But if Congel does manage to erect his El Dorado, will it really help cure our country’ s addiction to scarce and highly polluting fossil fuel Or will it just be a cleverly marketed boondoggle that may create more environmental problems than it solves All by itself, the mall would boost America’ s solar-electric power capacity by nearly 10 percent. "On every level, this project astounds," Senator HIillary Clinton said in April, claiming that the mall could make the area a hub for clean technologies and deliver a shot of adrenaline to upstate New York’ s ailing economy. To help foot the bill for Congel’s project, Clinton and other politicians successfully persuaded Congress to provide financial incentives for mega-scale green development projects. (Destiny, of course, will face little competition to reap hose benefits.) From the article, we may note that ______.

TEXT A The ivory-billed woodpecker, if you haven’ t heard, is no longer extinct. In late spring, a group of 17 researchers announced in the online version of Science that they had spotted at least one member of this majestic species living in the cypress and tupelo swamps of eastern Arkansas. Once found everywhere in Southern hardwood forests, the ivory-billed woodpecker tumbled in population after the turn of the century, the victim of avid collectors and logging. It had last been seen in 1944, reduced to what Tim Gallagher, author of "The Grail Bird: Hot on the Trail of the Ivory-Billed Woodpecker," calls "a symbol of everything that has gone wrong with our relationship to the environment." "The Grail Bird" is the story of this remarkable rediscovery, told by one of the chief rediscoverers. The editor of Living Bird magazine, Gallagher began the book several years ago with milder ambitions. The plan was to interview anyone who had seen the bird -- or thought he or she had. Soon, though, he was swept into a web of tantalizing rumors and half-clues, propelled by the possibility that a living ivory-bill might yet be found. "If someone……could prove that this remarkable species still exists, it would be the most hopeful event imaginable: we would have one final chance to get it right, to save this bird and the bottomland swamp forests it needs to urvive." Hope was a thing with a three-foot wingspan. "The Grail Bird" is less an ecological study than a portrait of human obsession; if not for the outcome, it could as easily be a book about the hunt for Bigfoot. Gallagher stakes out swamps teeming with alligators and cottonmouths. He sifts through shady evidence, from fuzzy Instamatic photographs to bags of bark shavings -- peeled, possibly, by the ivory-billed woodpecker in its search for beetle grubs. He suffers bloodied feet and an infected knee. His closest companion, Bobby Ray Harrison, a wildlife photographer and an arts professor at Oakwood College, dresses in full camouflage gear and canoes with a camcorder attached to his helmet. Sasquatch chasers," Gallagher’ s wife calls them. Yet for all the shenanigans, his book is an insightful look at what most biological fieldwork involves: a lot of sweating, sitting and waiting for ghosts to -- maybe -- make themselves real. As tales go, "The Grail Bird" isn’t the most stylishly told. Gallagher lets his characters talk at too-great length, and the incidental details are sometimes overly incidental. ("After pigging out on bad burgers, we got a room at a cheap motel and quickly fell into a deep, exhausted sleep with lots of snoring.") But most readers probably won’ t mind. As some rivers are to be enjoyed not for the quality of the water but for the quality of the stones to be found therein, so it is with some books. Gallagher presents a series of lively characters: Fielding Lewis, a former Louisiana state boxing commissioner who in 1971 took two fuzzy photographs of the wood pecker that were subsequently -- and perhaps mistakenly -- discredited; an anonymous "woodpecker whisperer" who claims to have a telepathic connection to the birds, even a thousand miles away. (One group of searchers failed, they were told, because they were noisily scaring off the bird.) Oddly missing from this recounting is any extended focus on the ivory-billed woodpecker itself. Granted, the bird has been invisible for decades, a presence notable largely for its absence. Still, the book might have given us the animal’ s history in more detail -- something to convey the visceral appeal of this "grail." Without that, the quest -- though triumphant -- at times feels hollow, and the fulfillment of the author’ s obsession veers perilously close to sounding like an end in itself. Which of the following statements is NOT true
TEXT E The biggest problem facing Chile as it promotes itself as a tourist destination to be reckoned with, is that it is at the end of the earth. It is too far south to be a convenient stop on the way to anywhere else and is much farther than a relatively cheap holiday’ s flight away from the big tourist markets, unlike Mexico, for example. Chile, therefore, is having to fight hard to attract tourists, to convince travelers that it is worth coming halfway round the world to visit. But it is succeeding; not only in existing markets like the USA and Western Europe but in new territories, in particular the Far East. Markets closer to home, however, are not being forgotten. More than 50% of visitors to Chile still come from its nearest neighbor, Argentian, where the cost of living is much higher. Like all South American countries, Chile sees tourism as a valuable earner of foreign currency, although it has been far more serious than most in promoting its image abroad. Relatively stable politically within the region, it has benefited from the problems suffered in other areas. In Peru, guerrilla warfare in recent years has dealt a heavy blow to the tourist industry and fear of street crime in Brazil has reduced the attraction of Rio de Janeiro as a dream destination for foreigners. More than 150,000 people are directly involved in Chile’ s tourist sector, an industry which earns the country more than US $ 950 million each year. The state-run National Tourism Service, in partnership with a number of private companies, is currently running a worldwide campaign, taking part in trade fairs and international events to attract visitors to Chile. Chile’ s great strength as a tourist destination is its geographical diversity. From the parched Atacama Desert in the north to the Antarctic snowfields of the south, it is more than 5,000 km long. With the Pacific on one side and the Andean Mountains on the others, Chile boasts natural attractions. Its beaches are not up to Caribbean standards but resorts such as Vina del Mar are generally clean and unspoiled and have a high standard of services. But the trump card is the Andes mountain range. There are a number of excellent ski resorts within one hour’ s drive of the capital, Santiago, and the national parks in the south are home to rare animal and plant species. The parks already attract specialist visitors, including mountaineers, who come to climb the technically difficult peaks, and fishermen, lured by the salmon and trout in the region’ s rivers. However, infrastructure development in these areas is limited. The ski resorts do not have as many lifts as their European counter parts and the poor quality of roads in the south means’ that only the most determined travelers see the best of the national parks. Air links between Chile and the rest of the world are, at present, relatively poor. While Chile’ s two largest airlines have extensive networks within South America, they operate only a small number of routes to the United States and Europe, while services to Asia are almost non-existent. Internal transport links are being improved and luxury hotels are being built in one of its national parks. Nor is development being restricted to the Andes. Easter Island and Chile’ s Antarctic Territory are also on the list of areas where the Government believes it can create tourist markets. But the rush to open hitherto inaccessible areas to mass tourism is not being welcomed by everyone. Indigenous and environmental groups, including Greenpeace, say that many parts of the Andes will suffer if they become over-developed. There is a genuine fear that areas of Chile will suffer the cultural destruction witnessed in Mexico and European resort. The policy of opening up Antarctica to tourism is also politically sensitive. Chile already has permanent settlements on the ice and many people see the decision to allow tourists there as a political move, enhancing Santiago’ s territorial claim over part of Antarctica. The Chilean Government has promised to respect the environment as it seeks to bring tourism to these areas. But there are immense commercial pressures to exploit the country’ s tourism potential. The Government will have to monitor developments closely if it is genuinely concerned in creating a balanced, controlled industry and if the price of an increasingly lucrative tourist market is not going to mean the loss of many of Chile’ s natural riches. According to the author, Chile’ s greatest attraction is ______.
