[EX Q]: Article: As the nights get lounger, those who suffer from the winter blues will be planning ways to escape to the sunshine. But there may be a much simpler way of cheering yourself up... simply shining a bright light into your ear canal. Up to one in four Britons suffer from seasonal affective disorder, with seven per cent of the population having full-blown SAD. It is caused by the brain not receiving enough daylight which is needed to trigger serotonin , a hormone that regulates mood. Symptoms range from mild lethargy to depression and insomnia, but a cure might be in sight. Two clinical trials, run by Valkee - who make a device that can shine light into your ear - and the University of Oulu in Finland, have found that carefully targeted light can help prevent the condition. Juuso Nissila, Valkee's co-founder and chief scientist said: "We presented earlier that the human brain is sensitive to light". "These two clinical trials demonstrate that channeling bright light via ear canal into brain's photosensitive areas effectively prevents and treats seasonal affective disorder." The University of Oulu reported that in their first study, 92 per cent of the patients with seasonal affective disorder achieved full remission after a month of daily eight-to-12 minute doses of light from the Valkee. Time Takala, chief physician at the Oulu Deaconess Institute said: "These two trials show that bright light channeled into the brain via ear canal is an important future method to treat seasonal affective disorder." Valkee launched its bright light headset in August 2010. It is classed as a medical device under EU regulations. The device channels bright light direct to the brain via the ear canal to prevent and cure depression, mood swings and even circadian-rhythm disorders such as jet lag. It costs PS185 and looks like an iPod - only the earphones emit light rather than sound.
Question: How many Britons suffer from seasonal affective disorder?

[EX Q]: Article: In America today, there are almost as many people making their living as bloggers as there are lawyers. Already more Americans are making their primary income from posting their opinions than Americans working as computer programmers or fire fighters The best studies we can find say we are a nation of over 20 million bloggers, with almost 2 million Americans getting paid by the word, the post, or the click - whether on their site or someone else's. The Information Age has developed many new professions, but blogging could well be the one with the biggest effect on our culture. What started as a discussion forum for politics and new technologies has now been used in health care, the arts, fashion and just about every other imaginable area of life. What started as a hobby for volunteers is becoming big business for newly appearing sites, for companies that now depend upon their reviews and for the people who work in this new industry. All this fits with the trend toward Opinion TV. Less and less of our information flow is devoted to gathering facts, and more and more is going towards popularizing opinions. Twenty-four-hour news channels have been replaced by 24-hour opinion channels. Some bloggers even serve as "spokesblogers"-paid by advertisers to blog about the products. They are highly paid and they have to report long hours-50 to 60 hours a week. Bloggers make money if their consumers click the ads on their sites. Some sites even pay writers by the click, which is of course a system that encourages using shocking words or doing whatever it takes to get noticed. For now, bloggers say they are very happy in their work, reporting high job satisfaction. But what happens if they lose work? Are they considered journalists under shield laws ? Is there someone to complain to about false blogs or hidden conflicts? There are more questions than answers about America's Newest Profession.
Question: What's the latest profession trend in today's America?
Options: (A) Many lawyers take bloggings as a part-time job (B) More people are beginning to earn a living by blogging (C) Bloggers earn much more than computer programmers (D) Firefighters are giving up the profession in increasing numbers

[EX Q]: Article: New research finds a link between poverty and poor decision making. The findings may explain why poor people sometimes make bad choices that continue their hardship. Earlier studies have found the poor less likely to escape poverty. But there has been little research on why the poor make decisions that make their lives harder. Until recently, it was economists who studied poverty, not psychologists. Eldar Shafir, a psychologist in Princeton University says now scientists from both fields work together. Mr. Shafir and his team did two experiments. One took place at a shopping center in New Jersey. Another was carried out among sugar cane farmers in rural India. The New Jersey experiment involved individuals with low paying jobs and others belonged to the middle class. All the volunteers were asked what they would do if their cars needed repairs. The volunteers were given two imaginary situations. In the first, the car repairs cost $ 150. In the second, $ 1,500. "And what we found is that the poor and the rich performed equally well on almost all the tests. " Not so when the researchers raised the repair costs to $ 1,500. "Now the poor performed significantly worse. " The poorer lost about 13 IQ points on average. This is about the loss experienced when a person has not slept for one night. The scientists then wondered if the same person reacted differently when he was rich and when he was poor. The Indian sugar cane farmers earn most of their money once a year, when the harvest comes in. But the money often does not last through the year. "So they find themselves basically rich after the harvest when the income comes in and poor just before the harvest. The researchers gave them tests similar to the ones taken by the people in New Jersey. They tested the Indian farmers before the harvest and after. And the results were much the same as with the mall shoppers. "They performed much more slowly and with many more mistakes when they were poorer than when they were richer. " Mr. Shafir says the results support 50 years of research that shows all humans have limited mental power to deal with things in life. "And so the insight here is that, having not enough of something in a way makes it harder to make good decisions for everything else. "
