Good Genes Mean Long Life Scientists have discovered that living to the age of 100 may have nothing to do with the lifestyle you lead and everything to do with the type of genes you have. For the lucky carriers of "Methuselah" genes, worries over smoking, eating unhealthily and not getting enough exercise may not be as necessary as to those of us without the special gene pattern . The "Methuselah" genes could give extra protection against the diseases of old age such as cancer and heart disease. They could also protect people against the effects of the unhealthy lifestyles that we believe will lead us to an early death, scientists say. However, the genes are very rare. The genes include ADIPOQ, which is found in about 10 percent of young people but in nearly 30 percent of people living past 100. They also include the CETP and the ApoC3 genes, which are found in 10 percent of young people, but in about 20 percent of people over 100 years old. Some of those genes were discovered by a research group at the Albert Einstein College of Medicine in New York, led by Professor Nir Barzilai. The team studied the genes of over 500 people over 100 years old, and their children. The studies show that tiny mutations in the make-up of some genes can greatly increase a person's lifespan . Barzilai told a Royal Society conference that the discovery of such genes gave scientists clear targets for developing drugs that could prevent age-related diseases, allow people to live longer and stay healthy. David Gems, a researcher at University College London, believes that drugs to slow ageing will become widespread. "If we know which genes control longevity then we can ... target them with drugs. That makes it possible to slow down ageing," he told The Times. "Much of the pain and suffering in the world are caused by ageing. If we can find a way to reduce that, then we are obliged to take it." Which of the following statements is TRUE of the research led by Professor Nir Barzilai? A) The team studied the genes of over 100 people over 100 years of age. B) The researchers found that mutations in certain genes lead to longer life. C) The researchers found ways to develop drugs that could cure age-related diseases. D) The study suggested that most people have genes that could lengthen their lives.

Forty years ago, Finland was a small country with ordinary public schools. Today, Finland is still small but no one calls Finland's public schools ordinary anymore. In 2000, the Finns surprised the world when their 15yearolds scored at the top of a closelywatched international exam called the PISA, the Program for International Student Assessment. Finland has stayed near the top ever since, while the US scores around the middle. Pasi Sahlberg, an official of Finland's Ministry of Education and Culture, is in Seattle this week to share the story of Finland's success, and what states like Washington can learn from it. Sahlberg's message, although he is too polite to put it so directly: Stop testing so much. Trust teachers more. Give less homework. Shorten the school day. On Tuesday, in a room filled with teachers, principals, professors, schoolboard members and policy makers, Sahlberg joked about the Finns' reputation for being a quiet, humble people. When Finland hit the top of the PISA, he said, the biggest disbelievers were Finns. More seriously, he said, Finland never set out to create the world's top school system. Instead, he said, the country decided in the 1970s that it wanted to ensure that a student's success didn't depend on family background. To achieve that goal, Finland relied on cooperation among teachers and schools, rather than on competition. Rather than judges teachers and schools based on test scores, he said, Finland puts trust in its teachers and principals. Teachers develop the curriculum in Finland, and design their own tests. There are no national tests, except one at the end of high school. That's just the start. Along with a shorter school day, Finnish students don't even start school until they are 7 years old. Many primary schools have a policy against giving homework. But Finland, he said, succeeded in part by adapting ideas from the US and other countries. And those countries, he said, can learn from Finland, too. People first learned Finland's success in education from _ . A) its ordinary public schools B) its international exchange students C) lectures given by Pasi Sahlberg D) its students' performance in an International exam
