user: Ques: Article: Just five minutes of exercise a day outdoors can improve mental health, according to a study. Researchers from the University of Essex, UK have found that as little as five minutes of a "green activity" such as walking, gardening, cycling or farming could help to improve mood and increase self-esteem  . Many studies have shown that outdoor exercise can reduce the risk of mental illness and improve a sense of well-being, but the new study, led by Jules Pretty and Jo Barton, was the first to determine how much time needed to be spent on green exercise for the benefits to show. Barton and Pretty looked at data from 1,252 people of different ages, genders   and mental health status   taken from 10 studies in Britain. They analyzed their different outdoor activities including walking, gardening, cycling, fishing, boating, horse-riding and farming in locations such as a park, garden or nature trail  . They found that the mental health changes were seen after just five minutes. With longer periods of time exercising in a green environment, the positive effects were more apparent. Looking at men and women of different ages, the researchers found the health changes were particularly strong in the young and the mentally ill. Green and blue A bigger effect was seen with exercise in an area that also contained water - such as a lake or river. "This is because historically we are drawn to water to survive and it is in our genetic   make-up to be at one with nature," the researchers wrote in their report. Pretty said those who were generally inactive, or stressed, or with mental illness would probably benefit the most from "green exercise". "Employers, for example, could encourage staff in stressful workplaces to take a short walk at lunchtime in the nearest park to improve mental health." He also said exercise programs outdoors could benefit youth offenders. Question: What is the main problem discussed in this article? Yes or no, is the answer "Outdoor exercise."?
Ans: No

Ques: Article: When you're surfing the Internet on your laptop from your dorm or home, do you know your personal details are being gathered secretly? And would you be surprised to know the information may be sold cheaply to advertisers and marketers? According to an investigation by The Wall Street Journal, all it takes is a tiny file in a computer-a single code consisting of a long series of numbers and letters to record the computer user's age, gender, location, favorite movies and hobbies. The newspaper reports that Lotame Solutions Inc., a New York company, uses sophisticated   software called a " beacon" to capture what people are typing on a website. Lotame packages that data into profiles   about individuals, only without their names, and sells the profiles to companies seeking customers. Batches of such data may be sold for a few dollars. The Wall Street Journal survey discovered that spying on Internet users is one of the fastest-growing businesses on the World Wide Web. The "cookie" a tiny text file put on your PC by websites or marketing firms which might be used to remember your. preferences for one site, or to track you across many sites is already old news. There are new and more complex tools such as "beacons " which scan in real time what people are doing on a webpage. These beacons instantly assess the Internet user's location, income, shopping interests and even medical conditions. Millions of Internet users around the world also face unprecedented   threats. Private, sensitive, personal and business information is being gathered and sold without their knowledge. Companies insist the information they gather is anonymous and the data is used harmlessly. But the technology has grown so powerful that even some of the biggest websites in the US don't know that they were installing intrusive files on visitors' computers. These include MSN. com and Yahoo. com. Next time you visit a webpage and find an ad banner advertising something you've been planning to buy, don't be amazed that your computer can read your mind.

Ques: Article: Inspired by a 9-year-old cyclist who uses only part of one hand, a group of University of Guelph students has won an international award for their invention--a bike brake lever  . It pulls both the front brake and the back brake at the same time. Lauren Turner was able to ride her bike, but not as confidently and quickly as her friends. "She couldn't use the front brake. She was only using the back brake, but the front brake makes you stop twice as fast," says Micha Wallace, who with Katie Bell, Anina Sakaguchi and Andrew Morris won second prize in the James Dyson Awards for their single-handed bike braking lever. "She used it all last summer and she had no problems. She said it helped her go faster because she felt more confident in her braking abilities. She felt safer." says Wallace. The invention was the fourth-year design project for the four students. They designed, tested and created a prototype  within a four-month period. When Wallace heard about the James Dyson Awards on the news, she and her co-inventors entered their project in the UK-based contest. The contest mainly rewards student designers who create products that improve the way we live. The Guelph students collected the second prize -PS2,000 for them, plus PS500 for their school. As well, they had a chance to meet James Dyson, a UK inventor. While praising the students for their creativity, Dyson said the single-handed lever could improve safety for all cyclists. "By using both brakes at once," he explains, "you could prevent the possibility of flying over the handlebars and ending up with an injury." The students are hoping to sell the patent to a major company. It may be used in other devices that require two hands for operation. Question: What can we know about the inventors of the brake lever? Yes or no, is the answer "They won their schoolPS500 for their invention."?
Ans: No

Ques: Article: On June 15th,2012,millions of people watched as 33yearold Nik Wallenda walked across one of the world's greatest waterfalls on a tightrope .What made the 25-minute walk that was televised live and watched by over 13 million people worldwide even more amazing,is that it was done over the Niagara Falls-An action that had never been attempted before. Even though Nik was wearing a harness ,a safety measure provided by ABC,the television network that broadcast the event,his action to keep his balance against the strong winds made for some heart-stopping  moments for the audience.

While he described the whole experience as peaceful and relaxing,Nik said his biggest challenges came from a totally unexpected source-his 40 pound balancing pole.The balancing pole was so heavy that he could hardly carry it on the tightrope.

A 5,000-foot tightrope walk across the Grand Canyon.While the one across the Niagara Falls took years of planning because he had to convince the US and Canadian officials,this one should happen in the very near future.That's because,the Florida resident has already been granted  a permit by the Canyon officials.5 Question: What made the audience hold their breath during Nik's performance?
