[Q]: Article: BC Social Report, August 14, 2010 Scandinavians may spend a lot of the winter in darkness but they are the happiest people in Europe, according to a study showed this month. Countries like Denmark and Finland scored highest on the study of happiness in Europe carried out by Cambridge University, which also found that the sunny southern countries of Italy, Portugal and Greece got the least joy out of life. The survey entitled: "No Man is an Island" showed that countries where people enjoy time with friends and family, have trust in government and national institutions were more likely to be happy than those living in a sunny climate. The study rated respondent on their overall sense of happiness and life satisfaction on a _ of one to 10. Danes --who expressed a high level of trust in their politicians and public institutions--came top of the field at 8.3. Italians--who reported lower levels of satisfaction with their national quality of government--came last at 6.49.' "Italy, Greece, Portugal, Germany and France report the lowest levels of happiness while the Scandinavian Countries, Netherlands and Luxembourg report the highest," the study said. Although Europeans are generally four times wealthier than their fathers and grandfathers, their levels of happiness are either equal to or lower than 40 years ago. The study also looked at factors contributing to happiness within countries and surprisingly found that an interest in politics actually increased happiness. Lead researcher Luisa Corrado said tax cuts and throwing money at social problems appeared to have no effect on the happiness of citizens when compared with government policies which strengthened and supported wider social networks. "People are less naive ( ) than one would expect, politicians need to adapted their policies and target specific problems in specific areas," she said.

[Q]: Article: The longest bull run in a century of art-market history ended on a dramatic note with a sale of 56 works by Damien Hirst, Beautiful Inside My Head Forever, at Sotheby's in London on September 15th 2008. All but two pieces sold, fetching more than PS70m, a record for a sale by a single artist. It was a last victory. As the auctioneer called out bids, in New York one of the oldest banks on Wall Street, Lehman Brothers, filed for bankruptcy, starting the most severe financial crisis since the 1920s. The world art market had already been losing momentum for a while after rising confusingly since 2003. At its peak in 2007 it was worth some $65 billion, thinks Clare McAndrew, founder of Arts Economics, a research firm -- double the figure five years earlier. Since then it may have come down to $50 billion. But the market generates interest far beyond its size because it brings together great wealth, enormous egos , greed, passion and controversy in a way matched by few other industries. In the weeks and months that followed Mr. Hirst's sale, spending of any sort became deeply unfashionable. In the art world that meant collectors stayed away from galleries and salerooms. Sales of contemporary art fell by two-thirds, and in the most overheated sector, they were down by nearly 90% in the year to November 2008. Within weeks the world's two biggest auction houses, Sotheby's and Christie's, had to pay out nearly $200m in guarantees to clients who had placed works for sale with them. The current downturn in the art market is the worst since the Japanese stopped buying Impressionists at the end of 1989. This time experts suppose that prices are about 40% down on their peak on average, though some have been far more volatile . But Edward Dolman, Christie's chief executive, says, "I'm pretty confident we're at the bottom." What makes this fall different from the last, he says, is that there are still buyers in the market, while in the early 1990s, when interest rates were high, there was no demand even though many collectors wanted to sell. Christie's earnings in the first half of 2009 were still higher than in the first half of 2006. Almost everyone who was interviewed for this special report said that the biggest problem at the moment is not a lack of demand but a lack of good work to sell. The three Ds -- death, debt and divorce -- still deliver works of art to the market. But anyone who does not have to sell is keeping away, waiting for confidence to return.
Question: Which of the following statements is true?
Options: (A) .Sales of contemporary art fell dramatically from 2003 to 2008. (B) The art market didn't match many other industries in momentum. (C) The market generally went downward in the same way. (D) Some art dealers were awaiting better chances to come.
[A]: D

[Q]: Article: Robert Louis Stevenson was born in Edinburgh in Scotland in 1850. He had to end his college studies because his health was poor. He began to travel, looking for a place that was good for his health. And he wrote about his travels. Inland Voyage(1878) was about journeys by canoe on the rivers and canals of Belgium and France. Travels with a Donkey in the Cevennes followed it in next year. People loved his travel books, and they also found his poems beautiful. In 1879 he travelled to California in a very uncomfortable ship and then by train across the United States to San Francisco. He married in California, but his poor health made him and his wife travel again. Readers of his travel books and poetry were surprised when Treasure Island came out in 1883. It was not at all like his earlier writing, but both children and grown-ups loved it. Treasure Island was finished in Switzerland. Stevenson then continued to travel. He loved the islands of the southern Pacific Ocean, and he found that his health was better there. In the end, he and his wife made their home in Samoa. It was there that he wrote Kidnapped(1886), the story of David Balfour and Alan Breck. It was followed (but not immediately) by Catriona, which continues the story of David Belfour and tells of other exciting adventures of David and Alan, and of David's love for Catriona Drummond. In between the two stories about David Belfour came another surprising book, the "thriller" called The Strange Case of Dr Jekyll and Mr Hyde. Stevenson died in Samoa in 1894, and he is buried there.

Options: (A) He lived to be 50. (B) He was also a popular poet. (C) He was buried in his homeland. (D) He quit college because he was poor.
