input: Please answer the following: Write a multi-choice question for the following article, with the given choices and answer: Article: After an absence of thirty years, I decided to visit my old school again. I had expected to find changes, but not a completely different building. As I walked up the school drive, I wondered for a moment if I had come to the right address. The dirty red brick houses had been swept away. In its place stood a bright, modern block. A huge expanse of glass extended across the face of the building, and in front, there was a well-kept lawn where previously there had been "an untidy gravel yard". I was pleased to find that it was bread time and that the children were all in the playground. This would enable me to meet some members of staff . On entering the building, I was surprised to hear loud laughter coming from what appeared to be the masters' common room. I could not help remembering the teachers in my time, all dressed in black gowns and high collars . And above all, I recalled Mr Garston whom we had nicknamed "Mr Ghastly", the headmaster who had iron discipline on staff and pupils alike. I knocked at the common room door and was welcomed by a smiling young man who introduced himself to me as the headmaster. He was dressed casually in a sports jacket, and his cheerful manner, quickly dispelled the image of Mr Ghastly. After I had explained who I was, the headmaster presented me to the teachers all of whom were a little younger than himself, and said he would take me round the school. Here the biggest surprise of all was _ me. Gone were the heavy desks of old with their deeply carved names; gone too, were the dark classrooms with their ink stained, dark brown walls, and their raised platforms for the teachers. The rooms now were painted in bright colors, and the children, far from sitting straight in their places, seemed almost free to do as they liked. I looked with envy as I remembered how, as a child, I had looked at the blackboard hardly daring to whisper to my neighbor. Options: A He had expected that the school had completely changed. B In the writer's time, all the teachers were dressed in black gowns and high collars. C There was a well-kept lawn in their school when he visited it. D An untidy gravel yard had disappeared. Answer: A He had expected that the school had completely changed. Question:

Please answer this: Write a multi-choice question for the following article, with the given choices and answer: Article: Scientists have not come close to understanding all the different kinds of life on the planet, but US researcher Craig Venter is already working on creating the first artificial life. Venter and his researchers made a breakthrough this August. They successfully moved the DNA of one type of bacteria to a yeast cell, changed it, then put it into another bacterial cell. "Bacteria have systems that protect them from foreign DNA," Venter explained to the BBC. In the experiment, the team managed to block this system. The experiment was performed on a simple type of bacteria called Mycoplasma mycoides. The team took the bacteria's genes and put them into a yeast cell. Putting the DNA in a yeast cell allowed the team to change the genes----in this case, taking out a gene that was not necessary for the bacteria to live. They then put the gene into a host bacteria cell. The cell went on to divide normally, producing new healthy bacteria. In January, the team created artificial genes of a new type of bacteria. Their next goal is to put the artificial DNA into a host cell to create a new species, according to a report inSciencemagazine. "If we don't make any errors, I think it should work and we should have the first artificial species by the end of the year," Venter said in the report. The first artificial life from is likely to be a simple man-made bacteria, to prove that the technology can work. But that form will be followed by more complex bacteria that turn coal into cleaner natural gas, or algae that can take in carbon dioxide and change it into fuel. Many scientists think it's good news to have this artificial life, but others are worried that the technology to create new organisms might end up in the wrong hands, with dangerous results. Options: A Venter and his team are the only scientists trying to create artificial life B The experiment was based on research into different kinds of life on Earth C A new type of bacteria was created in January D All scientists are not in favor of the research Answer: D All scientists are not in favor of the research Question:

input question: Write a multi-choice question for the following article, with the given choices and answer: 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... Options: A Art market in decline. B Up-to-date art auctions. C Volatility of art prices. D Shifted interest in arts. Answer: A Art market in decline. Question:???
