Input: Consider Input: 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.

Output: D

Input: Consider Input: Article: During a state of deep relaxation, several physiological changes take place in the body: the body's oxygen consumption is reduced; the heart beat decreases; muscle tension and sweating ease, and there is decreased sympathetic nervous system activity.This restful state not only allows the body to repair and restore itself, but it has a calming effect on the consciousness. How to achieve this state of relaxation, however, is a matter of opinion, and in some medical circles, a matter of controversy.A recent report by Dr.David Holmes of the University of Kansas in the journal "American psychologist" said that simply sitting in an armchair has just as many beneficial characteristics for the body as meditation does.Researchers of other relaxation techniques disagree.These experts believe that more structured techniques, such as meditation, lead to a condition of deep relaxation. The debate goes on, but one thing appears to be clear: the relaxation response can be reached by a number of methods, and the methods themselves are not as important as _ .One day, one method may work best; on another day, an alternative method may be more appropriate.Once you are aware of all the methods, you can find the one that works best on you. Some of the relaxation techniques are meditation, auto analysis and progressive muscle relaxation response.More than just sitting quietly in a chair, they have the added benefit of structure and discipline, and for these reasons appear to be more effective for most individuals.
Question: According to the passage, which of the following statements is NOT true when a person is in a state of deep relaxation?
Options: (A) The body takes in less oxygen. (B) The heart beats less frequently. (C) Muscles become tense and the body sweats easily. (D) The consciousness becomes more or less calmed.

Input: Consider Input: Article: People in China, as in other parts of the world, are waiting to see how U.S. President-elect Barack Obama will deal with global problems such as the current economic slowdown once he takes office. As Sam Beattie reports from Beijing, there is widespread hope for closer U.S.-Chinese cooperation. For many students in Beijing, Mr. Obama symbolizes all that is possible in the United States. He's a popular winner here, seen as a self-made man who has made it to the top. "I think he is very charming, and a president who can create a new era," said Zhang Wei, a university student. "I like him very much and most of my friends do too." Ni Weibo, another university student, agrees. "Sino-U.S. relations still need more cooperation," she said. "I think he will help take it to a new era." China's President Hu Jintao congratulated Mr. Obama within hours of his victory, saying he hoped bilateral ties could be made stronger. Political analysts here say China will be looking for the incoming president to avoid contentious issues such as Taiwan's independence, human rights and Tibet. Instead, they say Beijing would like Mr. Obama to focus on solving the global economic crisis, and to help China's slowing economy by opening up U.S. markets. But trade relations might be _ , says Renmin University's Professor of International Studies, Shi Yinhong. He warns, "There is a possibility that President Obama will take some protectionist measures which China will not accept, then trade disputes could develop to a degree that we have not seen ever before." Despite making the headlines, Mr. Obama faces some tough challenges in managing the U.S. relationship with China. China is now a stronger and more confident country than the China his predecessors dealt with. And in this time of economic uncertainty, analysts say it's a country with which Mr. Obama will want to maintain a good relationship.
Question: What is not mentioned in this passage?
Options: (A) What Barack Obama is expected to do in dealing with the US-China relationship. (B) Why Barack Obama will maintain a good relationship with China. (C) How Barack Obama will deal with the current economic slowdown. (D) What image Barack Obama has given to Chinese people.
Output: C
