New research shows that overweight or even mildly obese people have a lower risk of early death than people considered to be normal weight. Researchers examined the results of 97 studies. Most of the studies were less than 10 years old. They included almost three million adults from around the world, including the United States, Canada, China, Taiwan, Brazil, India and Mexico. The researchers at the National Center for Health Statistics found that people who are considered overweight or slightly obese were five to six percent less likely to die from all causes than people of normal weight. People with higher obesity ratings, however, had almost a 30 percent greater risk of death compared to normal-weight individuals. Katherine Flegal was the lead author of the study. She says she was not surprised that overweight people would not have a higher risk of death. "Because we'd actually already read a lot of this literature and realized it was likely that mortality rates for overweight would be at least not higher than normal weight. I guess I was a little bit surprised that it was definitely lower. And I was also surprised that the lower rates of obesity also didn't seem to differ from normal weight." But she says the difference in death rates appears to be small between normal-weight people and those who are overweight or mildly obese. The study has raised new questions about "body mass index," or BMI. This is a measurement of body fat as a ratio of height to weight. In recent years, many public health experts have promoted body mass index as a way to predict the risk of health problems. Bu t a person's BMI can be misleading in some cases. Steven Heymsfield ,the executive director of the Pennington Biomedical Research Center, says people can be physically fit and in good health, but might weigh more because they are more muscular. Still, Dr. Heymsfield says people should not think gaining extra weight is OK just because of the new findings. He says being at a healthy weight lowers the risk for heart disease... According to the new findings, the researchers found that _ . A) People with high obesity have a lower risk of early death than people with low obesity B) People with overweight have a greater risk of early death than people of normal weight. C) People with mild obesity are less likely to die than people of normal weight. D) People with obesity live much longer than people of normal weight.

Q: Argentina in the late nineteenth century was an exciting place.Around 1870,it was experiencing an economic boom,and the capital,Buenos Aires,attracted many people.Farmers,as well as a flood of foreigners from Spain and Italy,came to Buenos Aires seeking jobs.These jobs didn't pay well,and the people felt lonely and disappointed with their new life in the city.As the unhappy newcomers mixed together in the poor parts of the city,the dance known as the tango came into being. At the beginning the tango was a dance of the lower classes.It was danced in the bars and streets.At that time there were many fewer women than men,so if a man didn't want to be left out,his only choice was to dance with another man so that he could attract the attention of the few available women.Gradually,the dance spread into the upper classes of Argentinean society and became more respectable. In Europe at this time,strong interest in dance from around the world was beginning.This interest in international dance was especially evident in Paris.Every kind of dance from ballet to belly dancing could be found on the stages of the Paris theaters.After tango dancers from Argentina arrived in Europe,they began to draw the interest of the public as they performed their exciting dance in cafes.Though not everyone approved of the new dance,saying it was a little too shocking,the dance did find enough supporters to make it popular. The popularity of the tango continued to grow in many other parts of the world.Soldiers who returned to the United States from World War I brought the tango to North America.It reached Japan in 1926,and in 2003 the Argentinean embassy in Seoul hired a local tango dancer to act as a kind of dance ambassador,and promote tango dancing throughout South Korea.
