PROBLEM: Context: Mahjong, that favorite pastime of "old folks" in Shanghai, is finding a new audience among younger players, and many university students are becoming mad about this traditional Chinese game. Students at Fudan University have even formed a Mahjong club. This resurgence of the game, however, is not without its critics. Some people still associate the game with gambling and for many years Mahjong was banned in China. One critic, surnamed Meng, was quoted as saying, "Mahjong is a bad custom that will distract students from studies." But Yu Guangyuan, former vice-president of the Chinese Academy of Social Sciences , says Mahjong is a "healthy, scientific, friendly mind game." Mr. Yu's opinion seems to be shared by the majority of Chinese. They see the game as an activity that requires great concentration and intellectual skill. They also see the game as an important part of Chinese culture and a pastime that brings family and friends closer together. This Spring Festival many families will no doubt spend hours around the Mahjong table getting reacquainted with each other. For them, playing Mahjong is a way of spending quality family time. No one knows who invented Mahjong. Some say it was Confucius, others say the current form of the game was developed right here in Shanghai in the late19th century. It is certainly because of Shanghai that the game enjoys its worldwide popularity. It was brought to America in the 1920s and has since spread throughout Europe and other parts of Asia. There is now a World Championship of Mahjong which is held every year. This year's championship was held in Chongqing and attracted players from America, Europe and Russia, as well as students from Peking University, Tshinghua University and Nankai University. There was no prize money, but the players delighted in using their wits and their understanding of statistics and probability theory to defeat their clever opponents. Of course, Mahjong doesn't have to always be that intense. For young people it can be a way to relax and to socialize, a chance to get away from their computers and talk to other people face to face. So, this Spring Festival, why not get out the "old folks" tiles: it's good to be mad about Mahjong! 
 Question: What is the best title of the passage?

SOLUTION: mad about mahjong

PROBLEM: Context: The movie is based on the true story of two British athletes competing in the 1924 Summer Olympics in Paris. Englishman Harold Abrahams (Ben Cross), who is Jewish, overcomes anti-Semitism and class prejudice in order to compete against the "Flying Scotsman", Eric Liddell (Ian Charleson), in the 100 metre race.Opening in 1919 England, Harold Abrahams enters Cambridge University, where he meets with anti-Semitism from the staff, but enjoys participating in the Gilbert and Sullivan theatre club. He becomes the first person to ever complete the Trinity Great Court run: running around the court in the time it takes for the clock to strike 12. Abrahams achieves an undefeated string of victories in various national running competitions. Although focused on his running, he falls in love with a famous Gilbert and Sullivan soprano, Sybil (Alice Krige).Meanwhile in Scotland, Eric Liddell (Ian Charleson), born in China of Scottish missionary parents, is in Scotland. His devout sister Jennie (Cheryl Campbell) disapproves of Liddell's plans to pursue competitive running. But Liddell sees running as a way of glorifying God before returning to China to work as a missionary.Abrahams and Liddell meet for the first time in London in June 1923 when they first race against each other in a British open. Liddell beats Abrahams who takes it extremely badly. But Sam Mussabini (Ian Holm), a professional trainer whom Abrahams had approached earlier, offers to take him on to improve his technique. This attracts criticism from the Cambridge college masters (John Gielgud and Lindsay Anderson). In their meeting with Abrahams, the Cambridge masters allege it is ungentlemanly for an amateur to "play the tradesman" by employing a professional coach. Abrahams realizes this is a cover for their anti-Semitism and class entitlement, and dismisses their concern.Meanwhile, when Liddell accidentally misses a church prayer meeting because of his running, his sister Jennie upbraids him and accuses him of no longer caring about God. But Eric tells her that though he intends to eventually return to the China mission, he feels divinely inspired when running, and that not to run would be to dishonor God: "I believe that God made me for a purpose. But He also made me fast, and when I run, I feel His pleasure."The two athletes, after over a year of training and racing, are accepted to represent Great Britain in the 1924 Summer Olympics in Paris, France. Also accepted are Abrahams' Cambridge buddies, Lord Andrew Lindsay (Nigel Havers), Aubrey Montague (Nicholas Farrell), and Henry Stallard (Daniel Gerroll) whom join the UK team.While boarding the boat to Paris for the Olympics, Liddell learns from the newspapers that the event for his 100 meter race will be on a Sunday. Liddell refuses to run the race despite strong pressure from the Prince of Wales (David Yelland) as well as the head of the British Olympic committee, Lord Cadogan (Patrick Magee) because Liddell's Christian convictions prevent him from running on the Christian Sabbath (Sunday).Hope appears in the form of Liddell's teammate Lord Andrew Lindsay. Having already won a silver medal in the 400 meter hurdles, Lindsay proposes to yield his place in the 400 meter race on the following Tuesday to Liddell. Liddell gratefully agrees. His religious convictions in the face of national athletic pride make headlines around the world.Liddell delivers a sermon at the Paris Church of Scotland that Sunday, and quotes from Isaiah 40, verse 31:"But they that wait upon the LORD shall renew their strength; they shall mount up with wings as eagles; they shall run, and be not weary; and they shall walk, and not faint."Meanwhile, Abrahams is badly beaten by the heavily favored and more experienced United States runner Charles Paddock (Dennis Christopher) in the 200 meter race who wins the gold medal, while Abrahams takes a second place silver medal. Abrahams knows that his last chance for a gold medal will be the 100 meter run. He competes in the 100 meter sprint and wins, beating Paddock and the rest of the Americans.On Tuesday, just before Liddell's race, the American coach remarks to his runners that Liddell has little chance 
 Question: When does the 400-metre race take place?

SOLUTION: on a tuesday

PROBLEM: Context: Philadelphia (Ph) chromosome is the cytogenetic hallmark of chronic myeloid leukemia (CML). The translocation forms a chimeric gene, bcr-abl, which generates BCR-ABL. This fusion protein constitutively activate ABL tyrosine kinase and causes CML. Imatinib mesylate is a selective tyrosine kinase inhibitor on ABL, c-Kit and PGDF-receptor, and functions through competitive inhibition at the ATP-binding site of the enzyme, which leads to growth arrest or apoptosis in cells that express BCR-ABL. Imatinib has revolutionized the management of patients with CML, and at a dose of 400 mg daily has become the current standard therapy for newly diagnosed patients with CML even when they have HLA-matched family donors. Although imatinib therapy has only a 5-year history, it is hoped that CML will be cured with this drug and with forthcoming second-generation tyrosine kinase inhibitors as well as by allogeneic stem cell transplantation in patients who have become resistant to these drugs. 
 Question: What tyrosine kinase, involved in a Philadelphia- chromosome positive chronic myelogenous leukemia, is the target of Imatinib (Gleevec)?

SOLUTION:
bcr-abl
