Article: Scientists have devised a way to determine roughly where a person has lived using a strand ( ) of hair, a technique that could help track the movements of criminal suspects or unidentified murder victims. The method relies on measuring how chemical variations in drinking water show up in people's hair. "You're what you eat and drink, and that's recorded in your hair," said Thure Cerling, a geologist at the University of Utah. While U.S. diet is ly identical, water supplies vary. The differences result from weather patterns. The chemical composition of rainfall changes slightly as rain clouds move. Most hydrogen and oxygen atoms in water are stable, but traces of both elements are also present as heavier isotopes ( ). The heaviest rain falls first. As a result, storms that form over the Pacific deliver heavier water to California than to Utah. Similar patterns exist throughout the U.S. By measuring the proportion of heavier hydrogen and oxygen isotopes along a strand of hair, scientists can construct a geographic timeline. Each inch of hair corresponds to about two months. Cerling's team collected tap water samples from 600 cities and constructed a map of the regional difference. They checked the accuracy of the map by testing 200 hair samples collected from 65 barber shops. They were able to accurately place the hair samples in broad region roughly corresponding to the movement of rain systems. "It's not good for pinpointing ( )," Cerling said. "It's good for eliminating many possibilities." Todd Park, a local detective, said the method has helped him learn more about an unidentified woman whose skeleton was found near Great Salt Lake. The woman was 5 feet tall. Police recovered 26 bones, a T-shirt and several strands of hair. When Park heard about the research, he gave the hair samples to the researches. Chemical testing showed that over the two years before her death, she moved about every two months. She stayed in the Northwest, although the test could not be more specific than... Question: What is said about the rainfall in America's West? Yes or no, is the answer "The water it delivers becomes lighter when it moves inland."?

Article: prefix = st1 /London 01 April 2009 U.S. President Barack Obama and British Prime Minister Gordon Brown are calling for global unity as world leaders gather in London for an emergency economic summit . The president says no one country can fix the economic crisis. Mr. Obama stressed the need for all participants to seek common ground to deal with the economic crisis. "I am ly confident that this meeting will reflect enormous consensus about the need to work together to deal with these problems," said Mr. Obama. There are signs of tension, as the G20 summit prepares to begin its work in London. Some countries are blaming the United States for sparking the economic crisis through the deregulation of its financial scene - a move that sparked an economic recession . The president says the United Stateshas made mistakes, but so did other countries whose regulatory systems could not keep pace with a changing financial sector. He says it is time to look for solutions. "At this point, I am less interested in identifying blame, than in fixing the problem," he said. President says differences are overstated. France and Germanysay the emphasis should be on regulatory reform. French President Nicholas Sarkozy even told an interviewer that he might walk out of the summit, if nations fail to agree on stricter regulation of global financial markets. Brown predicts no walkouts. President Obama says reports of differences are overstated. And, Prime Minister Brown predicts no one will walk away from the summit and its important work." I am confident President Sarkozy will not be here for the first course of our dinner, but will still be sitting as we complete our dinner this evening," said Mr. Brown. Mr. Brown says "Never before has the world come together in this way to talk about an economic crisis," he said. "Any of the crises we have seen since the second World War, you have not had this level of international cooperation." Question: Differences between leaders at the summit can be seen from the fact that _ . Yes or no, is the answer "French President told an interviewer that he might walk out of the summit."?

Article: Health insurance is a great concern to Americans now. It's likely that many Americans lack health insurance with the economy having no sign of picking up. The National Academy of Sciences reported Thursday. "Unless health insurance is made more affordable, the number of uninsured Americans is likely to continue growing over time," said Mary Sue Coleman, co-chairwoman of the committee that wrote the report. The report is the first six planned by the institute of Medicine over two years. The series is planned to find out who lacks health insurance and why, and determine what the consequences are and provide the groundwork for debate on how to correct the problem. The institute is part of the academy, a private organization supported by Congress to advise the government of scientific matters. This first report seeks to draw a picture of the millions who lack insurance. It does not offer any recommendations. "Much of what Americans think they know about the uninsured is wrong," said Dr. Arthur Kellermann, a public health professor at Emory University Schools of Medicine in Atlanta, who also worked on the report. The Census Bureau reported last month that 38.7 million Americans went without coverage for all of 2000, compared with 39.3 million the year before, thanks to the booming economy. Experts say the trend is likely to reverse this year, given that the economy was slowing even before the Sep. 11 terrorist attacks. "Unfortunately, the recent economic slowdown might have reversed the modest gains in coverage for shorter periods." The report said that with insurance costs rising, more employers and individuals may conclude they are unable to afford coverage. Premium increases were often absorbed by employers in the strong economy of the 1990s, but that may not continue as the economy softens, the report said. The panel found that about 13.6 million of the uninsured work for employers that do not offer health insurance. Individually purchased coverage may be prohibitively costly. Question: What is the best title of the passage? Yes or no, is the answer "Millions of Americans lack health insurance"?
