[EX Q]: Article: 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.
Answer: To share the story of Finland's success in education.
[EX A]: What might be the author's purpose in writing the passage?

[EX Q]: Article: Petroleumis a very important mineral. It gives us heat and light. It gives us power for our cars, planes, and ships. Also, it gives us power for machines of all kinds. How is petroleum formed? Scientists believe petroleum comes from the remains of plants and animals (Remains are what is left after a plant or animal has died.) What exactly is petroleum? Petroleum is a mineral that is a mixture of hydrocarbons. It is an oily liquid, which may be brown, green, or black in colors. The word "petroleum" comes from Greek. It means "rock oil". Crude (, ) oil is petroleum that comes directly from deep in the ground. It is then taken to a refinery. a refinery is a kind of factory to refine oil. At a refinery the crude oil is separated into many parts. From the refined petroleum we get important things, such as gasoline, kerosene, fertilizer, detergents and a lot of other useful things. In fact, there are thousands of such things that we can get. Petroleum really is of great value!
Answer: " Petroleum" is a German word.
[EX A]: Which of the following is Not true?

[EX Q]: Article: The speed of light is often called a"constant ". New experiments show that may not be true, even within a vacuum. Sometimes, light slows a bit. The new research is"very impressive work", Robert Boyd toldScienceNews.An optical physicist at the University of Rochester in New York, he did not work on the study. He speaks of the new finding:"It's the sort of thing that's so obvious; you wonder why you didn't think of it first." Light travels as particles and as waves. Photons are the name given to those particles that represent the smallest possible amount of light. At their fastest, photons travel nearly 300 million meters (almost 1 billion feet) in a single second. That's fast enough to get to the moon and back in about 2.6 seconds. Scientists had long known, though, that they could slow light photons down by shining them through a material such as glass or water. Still, light moving through a vacuum has usually been assumed to move at a peak speed. That would seem to make sense. After all, a vacuum is a space with nothing in it to slow light down. In a new study, however, scientists show that even racing through a vacuum, light can slow. So the speed of light is more of a universal speed limit than an rule for how fast photons travel, the new data suggest. Miles Padgett led the new study. As an optical physicist, he works at the University of Glasgow in Scotland. He and his colleagues showed that the key to slowing light is to change the shape of a light wave. Padgett described how they did this in a paper published online January 22 inScience. His team raced a pair of photons. One traveled unchanged through a cable made from optical fibers. The other passed through a pair of devices that acted like lenses. A lens changes light: It can focus a spread-out beam of light on a point, for instance. The second photon passed through one device that changed the shape of its waveand another that changed it back to its original form. The first photon won the race. The second photon came in a tiny bit later, several quadrillionths of a second late for every meter of the race. The difference wasn't huge, but it was enough to measure. Most technology would not pick up such a small change, but it could be important to scientists who study short pulses of light. "I'm not surprised the effect exists,"Boyd toldScienceNews."But it's surprising that the effect is so large and strong."
Answer: Light photons can't travel through lenses easily.
