PROBLEM: Article: Adding math talk to story time at home is a winning factor for children's math achievement, according to a new research from the University of Chicago. The study from psychologists Sian Beilock and Susan Levine shows a marked increase in math achievement among children whose families used Bedtime Math, an iPad app that delivers engaging math story problems for parents and children to solve together. Even children who used the app with their parents as little as once a week saw gains in math achievement by the end of the school year. The app's effect was especially strong for children whose parents tend to be anxious or uncomfortable with math. Previous research from this group has demonstrated the importance of adults' attitudes about math for children's math success. For example, a recent study found that math-anxious parents who help their children with math homework actually weaken their children's math achievement. The new findings demonstrate that structured, positive interactions around math at home can cut the link between parents' uneasiness about math and children's low math achievement. "Many Americans experience high levels of anxiety when they have to solve a math problem, with a majority of adults feeling at least some worries about math," said Beilock, professor in Psychology and author of Choke, a book about stress and performance. "These math-anxious parents are probably less likely to talk about math at home, which affects how competent their children are in math. Bedtime Math encourages a dialogue between parents and kids about math, and offers a way to engage in high-quality math interactions in a low-effort, high-impact way." Study participants included 587 first-grade students and their parents. Families were given an iPad installed with a version of the Bedtime Math app, with which parents and their children read stories and answer questions involving math, including topics like counting, shapes and problem-solving. A control group received a reading app that had similar stories without the math content and questions related to reading comprehension instead. Children's math achievement was assessed at the beginning and end of the school year. Parents completed a questionnaire about their nervousness with math. The more times parents and children in the math group used the app, the higher children's achievement on a math assessment at the end of the school year. Indeed, children who frequently used the math app with their parents outperformed similar students in the reading group by almost three months in math achievement at year's end.

PROBLEM: 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.

SOLUTION: D

PROBLEM: Article: A pet parrot that spoke with a British accent when it disappeared from its home four years ago has been reunited with its owner ---- and the bird now speaks Spanish. The reunion was brought about by Teresa Micco, a Southern California veterinarian who mistook Nigel, an African gray parrot, for her own missing bird, the Daily Breeze reported on Sunday. Teresa Micco tracked Nigel's microchip to Darren Chick, a British man who lives in Torrance, California. "I introduced myself and said, 'Have you lost a bird?' "Micco told the newspaper. "He first said, 'No' But he thought I meant recently " When she checked on Chick's name and said she had his African gray parrot, "He looked at me like I was crazy. " He said his bird had gone missing for four years earlier. Little is known about Nigel's whereabouts for the past four years, but Chick says the bird's British accent is gone, and it now chatters in Spanish. Chick says last week's reunion brought tears of joy to his eyes---despite the fact that Nigel bit him when he first tried to pick him up. Micco said the behaviour was not unusual and that Nigel would settle back in soon enough. "He is doing very well," Chick told the newspaper. "It is really strange. I knew it was him from the minute I saw him" It is the fifth parrot reunion helped by Micco, who has been running advertisements for her own missing bird for nine months. That parrot, Benjamin, escaped in February when it flew out through a door that had been left open. Julissa Sperling found Nigel outside her home and brought him to Micco after seeing one of her advertisements. "He was the happiest bird. He was singing and talking all the time," Sperling said. "He was barking like my dogs. I am from Panama, and he was saying, 'What happened?' in Spanish."
