Well, he made it up. All of it, apparently. According to a report published on December 29th by Seoul National University in South Korea, its erstwhile employee Hwang Woo-suk, who had tendered his resignation six days earlier, deliberately falsified his data in the paper on human embryonic stem cells that he and 24 colleagues published in Science in May 2005. In particular, Dr Hwang claimed he had created 11 colonies of human embryonic stem ceils genetically matched to specific patients. He had already admitted that nine of these were bogus, but had said that this was the result of an honest mistake, and that the other two were still the real McCoy. A panel of experts appointed by the university to investigate the matter, however, disagreed. They found that DNA fingerprint traces conducted on the stem-cell lines reported in the paper had been manipulated to make it seem as if all 11 lines were tailored to specific patients. In fact, none of them matched the volunteers with spinal-cord injuries and diabetes who had donated skin cells for the work. To obtain his promising "results", Dr Hwang had sent for testing two samples from each donor, rather than a sample from the donor and a sample of the cells into which the donor’s DNA had supposedly been transplanted. The panel also found that a second claim in the paper — that only 185 eggs were used to create the 11 stem cell lines — was false. The investigators said the actual number of eggs used was far larger, in the thousands, although they were unable to determine an exact figure. The reason this double fraud is such a blow is that human embryonic stem-cell research has great expectations. Stem cells, which have not yet been programmed to specialise and can thus, in principle, grow into any tissue or organ, could be used to treat illnesses ranging from diabetes to Parkinson’s disease. They might even be able to fix spinal-cord injuries. And stem cells cloned from a patient would not be rejected as foreign by his immune system. Dr Hwang’s reputation, of course, is in tatters. The university is now investigating two other groundbreaking experiments he claims to have conducted — the creation of the world’s first cloned human embryo and the extraction of stem cells from it, and the creation of the world’s first cloned dog. He is also in trouble for breaching ethical guidelines by using eggs donated by members of his research team. And it is even possible that the whole farce may have been for nothing. Cloned embryos might be the ideal source of stem cells intended to treat disease, but if it proves too difficult to create them, a rough-and-ready alternative may suffice. The best title for the passage may be ______.

Questions 11 to 18 are based on the conversation you have just heard.
If you are what you eat, then you are also what you buy to eat. And mostly what people buy is scrawled onto a grocery list, those ethereal scraps of paper that record the shorthand of where we shop and how we feed ourselves. Most grocery lists end up in the garbage. But if you live in St. Louis, they might have a half-life you never imagined, as a cultural document, posted on the Internet. For the past decade, Bill Keaggy, 33, the features photo editor at The St. Louis Post-Dispatch, has been collecting grocery lists and since 1999 has been posting them online at www.grocerylists.org. The collection, which now numbers more than 500 lists, is strangely addictive. The lists elicit twofold curiosity — about the kind of meal the person was planning and the kind of person who would make such a meal. What was the shopper with vodka, lighters, milk and ice cream on his list planning to do with them In what order would they be consumed Was it a he or a she Who had written "Tootie food, kitten chow, bird food stick, toaster scrambles, coffee drinks" Some shoppers organize their lists by aisle; others start with dairy, go to cleaning supplies and then back to dairy before veering off to Home Depot. A few meticulous ones note the price of every item. One shopper had written in large letters on an envelope, simply, "Milk". The thin lines of ink and pencil jutting and looping across crinkled and torn pieces of paper have a purely graphic beauty. One of life’s most banal duties, viewed through the curatorial lens, can somehow seem pregnant with possibility. It can even appear poetic, as in the list that reads "meat, cigs, buns, treats". One thing Keaggy discovered is that Dan Quayte is not alone — few people can spell bananas and bagels, let alone potato. One list calls for "suchi" and "strimp" . "Some people pass judgment on the things they buy. " Keaggy says. At the end of one list, the shopper wrote "Bud Light" and then "good beer". Another scribbled "good loaf of white bread". Some pass judgment on themselves, like the shopper who wrote "read, stay home or go somewhere, I act like my morn, go to Kentucky, underwear, lemon. "People send messages to one another, too. Buried in one list is this statement: "If you buy more rice, I’ll punch you. "And plenty of shoppers, like the one with both ice cream and diet pills on the list, reveal their vices. Bill Keaggy’s studying on grocery lists suggests that ______.
