Article: For many blind people, computers are inaccessible. It can cost $1,000 to purchase "screen reader" software, but two blind computer programmers from Australia have solved this problem. Queensland University of Technology (QUT) graduate James Teh and business partner Michael Curran developed a free, open-source program, called NVDA, which provides a voice to read the words on a computer screen as the cursor moves over them. NVDA won the blind inventors an award in the grand final program of the ABC's New Inventors, which aired on September 23. They took home the award for an invention that "might make a real difference to people's lives or the environment." "A sighted person takes for granted that they can sit down at any computer and use it," Mr Teh said. "We really are in the information age -- everything is online these days. So access to computers for the blind is very important, which is why we wanted our software to be free." Mr Teh, who majored in software engineering at QUT, said blind students typically didn't have the money to purchase "screen reader" technology, at the time in their life when they most needed it. Now NVDA could be downloaded on to anyone's personal computer free of charge. "It can also be copied to a USB stick, which can be used on any PC at school or university, with no installation required," he said. Mr Teh and Mr Curran have drawn on their own experience as blind computer users to develop a product which has some unique features. For example, as the mouse moves up and down the screen, a sound becomes higher and lower to let you know where the cursor is located. NVDA has been translated into 27 languages, thanks to volunteer translators. To date, there have been over 50,000 downloads. Mr Teh and Mr Curran have been working on the project since 2006. They worked on their product without any pay for two years. When Mozilla offered some funding in 2008, Mr Teh was able to quit his day job and work full-time developing NVDA. Question: What do we know about Teh and Curran? Yes or no, is the answer "They know how the blind feel."?
(Answer)
Yes

Article: It is a finding which is certain to be hotly discussed. According to the latest research, women are brighter than men. For the first time in IQ testing, psychologists have found that female scores have risen above those of men. Since IQ testing began a century ago, women have been as much as five points behind. But that gap has been narrowing in recent years and this year women have moved ahead, according to James Flynn, leader of the research. "In the last 100 years the IQ scores of both men and women have risen but women's have risen faster," said Mr. Flynn. "This is a result of modernity, which is making our brains adapt and raising our IQ." One possible explanation is that women's lives have become more demanding as they multitask between raising a family and doing a job. Another is that women have a slightly higher potential intelligence than men and are only now realizing it. Mr. Flynn, who will publish his findings in a book, said more data was needed to explain the trend. "The full effect of modernity on women is only just starting," he added. He compared IQ result from countries in western Europe and from the United States, Canada, New Zealand, Argentina and Estonia. These showed that in westernized countries the gap in scores between men and women had become minimal . The data for making comparison was limited and could be carried out for only a few countries. It included Australia, where male and female IQs were found to be almost the same. In New Zealand, Estonia and Argentina, women scored slightly more than men. Mr. Flynn said, "As the world gets more complex, people are adapting." He added, "I suspect that the same trends are happening in Britain, although the data is too limited to be true." Question: On IQ tests in the past _ . Yes or no, is the answer "men were brighter than women"?
(Answer)
No

Article: The government-run command post in Tunis is staffed around the clock by military personnel, meteorologists and civilians. On the wall are maps, crisscrossed with brightly colors arrows that painstakingly track the fearsome path of the enemy. What kind of invader gives rise to such high-level monitoring? Not man, not beast, but the lowly desert locust . In recent months, billions of the 3-inch-long winged warriors have descended on Algeria, Libya, Morocco and Tunisia, blackening the sky and eating up crops and vegetation. The insect invasion, the worst in 30 years, is already creating great destruction in the Middle East and is now treating southern Europe. The current crisis began in late 1985 near the Red Sea. Unusually rainy weather moistened the sands of the Sudan, making them ideal seedbed for the locust, which lays its eggs in the earth. The insect onslaught threatens to create yet another African famine. Each locust can eat its weight (not quite a tenth of an ounce) in vegetation every 24 hours. A good-size swarm of 50 billion insects eats up 100,000 tons of grass, trees and crops in a single night. All $150 million may be needed this year. The U.S. has provided two spraying planes and about 50,000 gal. of pesticide. The European Community has donated $3.8 million in aid and the Soviet Union, Canada, Japan and China have provided chemical-spraying aircraft to help wipe out the pests. But relief efforts are hampered by the relative mildness of approved pesticides, which quickly lose their deadly punch and require frequent replications. The most effective locust killer dieldrin has been linked to cancer and is banned by many Western countries and some of the affected African nations. More than 5 million acres have been dusted with locust-killing chemicals; another 5 million will be treated by the end of June. On May 30, representatives of Tunisia, Algeria, Libya, Morocco and Mauritania will meet in Algiers to discuss tactics to wipe out the ravenous swarms. The move is an important step, but whatever plan... Question: The favorable breeding ground for the locust is _ . Yes or no, is the answer "wet land"?
(Answer)
No
