[Q]: Context: What did the arrival of the Internet and 24 hours news mean for British newspapers? At first, this looked like the end of printed newspapers. The national newspapers were worried that they would lose all the readers, so most of them decided to create an online version . But they still had a problem. How to make money? There was simply too much news and too much information freely available "out there". But was it accurate ( )? Whose opinions should we trust? A survey for a "good newspaper", and most of those said.they believe more of what they read in paid-for newspapers. Here was something newspapers understood--here was what they could offer: news plus comment and opinion. And the Internet now offered new opportunities. A newspaper was just that: news printed on paper. But the Internet now offered newspapers different places to print, and in different media. Many newspapers now have podcasts and video too. This may explain why the readership of newspaper online in the UK is very different from people who read printed newspapers. The most popular newspaper in the UK is The Sun, The "mid-market" audience mainly reads The Daily Mail. Online, it's a different story. The most popular is The Mail. And the next popular site is TheGuardian. In fact many of these browsers are not from the UK. The Mail and Guardian are among the most read newspapers in the USA. The Guardian, may become the largest English language paper on the web; a website with a newspaper attached! 
 Question: The largest English language paper on the Internet may be .
[A]: the guardian


[Q]: Context: Chronic myeloid leukemia (CML) arises as a consequence of a chromosomal translocation giving rise to the Philadelphia chromosome and Bcr-Abl oncogene. CML is a clonal disease of stem cell origin and an excellent example of a malignancy in which tumor-initiating cells may hold the key to disease eradication. The known molecular basis of CML has enabled the development of Abl-specific tyrosine kinase inhibitors, such as imatinib mesylate. However, the success of tyrosine kinase inhibitors, as rationally designed first-line therapies, has been tempered by problems of disease persistence and resistance. Residual disease has been shown to be enriched within the stem cell compartment and to persist at stable levels for up to 5 years of complete cytogenetic response. This finding has led to further searches for novel strategies aimed at eliminating these cells; such strategies may be essential in achieving cure. The most significant recent findings are discussed in this review. 
 Question: What tyrosine kinase, involved in a Philadelphia- chromosome positive chronic myelogenous leukemia, is the target of Imatinib (Gleevec)?
[A]: bcr-abl


[Q]: Context: Ryu (Ha-kyun Shin), a deaf man, works in a factory to support his ailing sister (Ji-Eun Lim) in desperate need of a kidney transplant. Ryu tries to donate one of his kidneys to his sister but is told that his blood type does not match that of his sister and so is not a suitable donor. After being laid off from his job by the factory boss, Ryu contacts a black market organ dealer who agrees to sell him a kidney suitable for his sister in exchange for 10,000,000 Korean won, plus one of Ryu's own kidneys. He takes the severance pay from his factory job and offers the money to the organ dealers, who take the money and one of his kidneys, but then disappear. Three weeks later, Ryu learns from his doctor that a kidney has been found for his sister and that the operation will cost 10,000,000 won, but since the organ dealers stole his money, he will not be able to pay for it.In need of money for the operation and in retaliation for his being fired, Ryu and his girlfriend, Yeong-mi (Doona Bae), a radical anarchist, conspire to kidnap the daughter of the boss who fired him. Instead, he realizes that the kidnapping would immediately put them under police suspicion, and they decide to kidnap Yu-sun (Bo-bae Han), the daughter of the boss's friend, Park Dong-jin (Kang-ho Song), another factory executive. The girl stays with Ryu's sister (thinking that Ryu is merely babysitting for a time), who takes care of her while the distraught Dong-jin arranges to pay her ransom. After Ryu collects the money and returns home, he learns that his sister has discovered his scheme and, unwilling to be involved or burden Ryu further, killed herself. Ryu takes Yu-sun and his sister's body into the countryside to bury her by a riverbed they used to frequent as children. While Ryu mourns, Yu-sun accidentally slips into the river and drowns.Days later, as Dong-jin mourns his daughter and swears revenge at the river bank, Ryu ambushes and murders the organ dealers. Dong-jin, having investigated the identities of the kidnappers, finds Yeong-mi and begins interrogating her. Yeong-mi apologizes for Yu-sun's death but warns him of her membership in a terrorist organization that, knowing Dong-jin's identity, will kill him if she dies. Dong-jin, unfazed by the threats, tortures her to death by electrocuting her. Ryu returns to Yeong-mi's apartment building and discovers the police removing her body on a stretcher. Ryu, consumed with grief, swears vengeance on Dong-jin.Ryu arrives at Dong-jin's residence in an attempt to kill him. He waits for some time, but Dong-Jin does not arrive: he is, in fact, waiting at Ryu's apartment. After Dong-Jin does not arrive, Ryu returns to his apartment. However, Dong-jin had previously set up an electric booby trap on his doorknob, which renders Ryu unconscious. Dong-jin then binds Ryu and returns him to the riverbed where Yu-sun died. After binding Ryu's hands and feet and bringing him chest-high into the water, an emotional Dong-jin acknowledges that although Ryu is a good man, he has no choice; Dong-jin then slashes Ryu's Achilles tendons, resulting in his drowning.Dong-jin drags Ryu back to shore and then drives off to a desolate location to bury the body. Once there, he begins to dig a hole, but soon a group of men arrives. They surround and stab Dong-jin repeatedly, finally attaching a note to his chest identifying themselves as the terrorist group of which Yeong-mi was part. The group leave Dong-jin dying beside his car with the bloody tools and bags he used to chop up, dismember, and package Ryu's body.(From Wikipedia.)
