American's genius with high technology may have put men on the moon, but there is growing doubt about its ability to solve human problems closer to home. In fact, a slight but significant change from purely technological solutions is already under way as scientists insist that answers to the world's problems will not come from an attractive exhibition of electronics and machines. Instead, as they see it, solutions must develop from a better understanding of the humans that drive the system and from a fuller appreciation of the limits and potential of the earth's resources. What this means is an increased emphasis on the life and earth sciences, on sociology, psychology, economics and even philosophy. More and more of the best minds in science, particularly young researchers, are being drawn into these developing fields. All this is not to say that technological creativity will not play a critical role in solving energy and food shortages, or that answers to environmental difficulties will not come from further advances in the same technologies that may have helped cause the problems. Where the real challenge lies, in the view of the new generation of scientists, is in finding ways to produce goods and meet the world's needs, using less of the raw materials that are becoming short. The author states all the following CXCEPT that _ . A) the development of present techniques cannot provide any answers to today's problems. B) an increasing number of young scientists are taking a great interest in biological and social sciences. C) many scientists have come to understand the limits of natural resources. D) many scientists argue that high technology is something but not everything.

Right now, 62 million girls worldwide are not in school. They're receiving no reading, no writing, no math--none of the basic skills they need to provide for themselves and their families, and contribute fully to their countries. Often, understandably, this issue is considered as a matter of result of a failure to invest enough money in educating girls. We can solve this problem, the argument goes, if we provide more scholarships and safe transportation and build more school bathrooms for girls. And it's true that investments like these are important for addressing our global girls' education crisis. But we cannot solve our girls' education problem until we deal with the broader cultural beliefs and practices that can help cause this crisis and make it continue. We know that legal and cultural change is possible because we've seen it countries around the world, including our own. A century ago, women in American couldn't even vote. Decades ago, it was perfectly legal for employers to refuse to hire women. But in each generation, brave people -both men and women--stood up to change these practices. They did it through individual acts like taking their bosses to court and even through national movements that brought changes. Cultural changes like these can encourage countries to make greater investments in girls' education. And when they do, that can cause a powerful effect that can cause even greater cultural and political progress for women. Girls who are educated marry later. Educated girls also can earn higher salaries. And when educated girls became healthy, financially secure, empowered women, they're far better equipped to achieve their needs and wishes, and challenge unjust laws and harmful practices and beliefs. But for me, this issue isn't just about politics or economics --- for me, this is a moral issue. As I've traveled the world, I've met so many of these girls. They're so hungry to realize their promise. They walk for hours each day to school, learning at rickety desks in bare concrete... The speaker made this speech in order to _ . A) give some facts about girls B) show how to educate girls well C) advertise girls to fight for their rights D) encourage people to care about girls' education

Ques: Trees are useful to man in three important ways: They provide him with wood and other products; they provide him shade;. and they help to prevent droughts and floods. Unfortunately, in many parts of the world, man has not realized that the third of these services is the most important.In his eagerness to make money from trees, he has cut them down in large numbers, only to find that without them he has lost the best friends he had. And besides, he is usually too careless to plant and look after new trees. So the forests slowly disappear. This does not only mean that man will have fewer trees. The results are even more serious: for where there are trees, their roots break up soil allowing the rain to sink in and also bind the soil, thus preventing it from being washed away easily;but where there are no trees, the rain falls on hard ground and flows away, causing floods and carrying away the rich top-soil. When the top-soil is gone, nothing remains but worthless desert. Two thousand years ago,a rich and powerful country cut down its trees to build warships, with which to gain itself an empire .It set up the empire, but, without its trees, its soil became poor and grew weak. When the empire fell to pieces, the home country found itself faced by floods and starvation . Land becomes desert after all trees are cut down because _ . A) roots of trees break up the soil B) there are too many rainfalls C) there are no larger trees to keep rain and protect the top-soil D) strong winds bring a lot of sand

Question: In 11 states across the United States, school buses are now doing more than just sending students. They also carry advertisements on the outside. Restaurants, companies, banks, and other businesses pay for the ads, hoping to attract more customers. Anci it's a way for the schools to make money. "We've seen a lot of income produced by the advertisements," said Devra Ash, who is the spokesperson for School District 11 in Colorado Springs, Colorado. She is also the mother of a third grader. Last year, District 11 made more than $ 15,000 from school-bus ads.Besides Colorado, states such as Arizona, New Jersey, and Texas allow ads on the outside of their school buses. The idea appears to be spreading. In Georgia, some school district leaders are suggesting putting ads on their buses ioo. School districts need to make sure that the ads are proper for kids, according to Michael Beauchamp, an officer of Alpha Media. This company works with businesses in several states to create ads for school buses. "The districts won't allow ads for things like beer, cigarettes,or politics," Beauchamp said. But not everyone is in favor of school buse.s having ads on the outside. That includes Georgia's Department of Education. Spokeswoman Dorie Nolt said, "We strongly believe that advertising on the outside of school buses distracts drivers and children. " Parents also hold different opinions about this. "If the advertisements can bring in money for the schools and help save some programs, that is great. " said Glenn Herdling of River Vale, New Jersey. His son is in second grade. Cindy Tomarchio of East Windsor, New Jersey, feels differently. "I know the schools can use the money, but kids already see enough advertising every which way they turn," she said.
