[Q]: Article: The concept of solar power satellites, or SPS, first put forward in the 1960s, is still not widely known by the general public. For example, at many public exhibitions about energy, SPS is not even mentioned. This is mainly because very little money has been spent on SPS research There are people who claim that SPS is unrealistic - because launch costs are much too high today; or because it is too far away. So why do we believe that it is important to continue to do researches on SPS? The reason is very simple. Humans are going to need huge amounts of electric power in coming decades. Within 50 years the world population is expected to double, while economic growth will continue around the world, especially in the poorer countries. But existing energy sources already face serious problems. They are limited; they are polluted; they are dangerous. So 50 or 100 years from now, where is our power going to come from? Nobody knows. And so we believe that new large-scale possibilities should be studied further. We must remember that humans have some choices concerning our future. To some extent we can choose the direction in which our civilization develops. And choices that are made in the coming decades - such as the energy sources that we will or will not use, will have major, long-term meaning for human life on earth. We believe that if research continues to show that SPS is environmentally and economically attractive, SPS will open the door to a much more attractive future for human civilization than any ground-based energy source, and one that the public will support and that young people will find challenging and exciting. Furthermore energy from SPS can be readily used in developing countries, as the SPS 2000 project will show, thus aiding economic development worldwide. In addition, by creating large commercial fund for space engineering, SPS will open the frontier of space to economic development, thus creating a limitless new field for the growth of the world economy.
Answer: The Future Energy- SPS
[A]: Which of the following may be the best title for the passage?

[Q]: Article: Forty years ago, Finland was a small, country with mediocre public schools. Today, Finland is still small but no one calls Finland's public schools mediocre any more. In 2000, the Finns surprised the world when their 15-year-olds scored at the top of a closely watched international exam called the PISA. Finland has stayed near the top ever since, while the U.S. scores around the middle. Pasi Sahlberg, an official with 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 bluntly: Stop testing so much, trust teachers more; give less homework; shorten the school day. On Tuesday, in a room filled with teachers, principals, professors, school-board 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, 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. "Finland relied on cooperation among teachers and schools, rather than on competition. Rather than judging 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 adopting ideas from the U.S. and other countries. And those countries, he said, can learn from Finland, too."
Answer: To ask the US to improve its education.

[Q]: Article: As many people hit middle age, they often start to notice that their memory and mental attention are not what they used to be. We suddenly can't remember where we put the keys just a moment ago, or an old friend's name, or the name of an old band we used to love. It happens to most of us, but is it unavoidable? Scientists are increasingly showing that there's actually a lot that can be done. It turns that the brain needs exercise in much the same way as our muscles do, and the right mental workouts can improve our basic cognitive functions. Now, a new San Francisco Web-based company has taken it a step further and developed the first "brain training program" designed to actually help people improve and regain their mental sharpness. Called Lumosity, it was designed by some of the leading experts from Stanford University. Lumosity is far more than an online place to exercise your mental skills. That's because they have combined these exercises with a Web-based program that allows you to systematically improve your memory and attention skills. Apparently it works. One study showed students improved their scores on math tests by 34 percent after using Lumosity for six weeks, greater gains than those made by other students in the same class, who were not training with the Lumosity program. The company says its users have reported clearer and quicker thinking, improved memory for names, numbers, directions, increased alertness and awareness, high mood, and better concentration at work or while driving.
Answer: To improve students' scores on test.
