Article: Owning a smartphone may not be as smart as you think. They may let you surf the Internet, listen to music and take photos wherever you are, but they also turn you into a workaholic . A study suggests that, by giving you access to emails at all times, the smartphone adds as much as two hours to your working day. Researchers found that Britons work an additional 460 hours a year on average as they are able to respond to emails on their mobiles. The study shows the average UK working day is between 9 and 10 hours, but a further 2 hours is spent responding to or sending work emails, or making work calls. Almost one in ten admits spending up to three hours outside their normal working day checking work emails. Some workers say they are on call almost 24 hours a day. Nearly two-thirds say they often check work emails just before they go to bed and as soon as they wake up, while over a third have replied to one in the middle of the night. The average time for first checking emails is between 6 am and 7 am, with more than a third checking their first email in this period, and a quarter checking them between 11pm and midnight. Ghadi Hobeika, marketing director of Pixmania, said: "The ability to access millions of applications has made smartphones invaluable for many people. However, there are disadvantages. Many companies expect their employees to be on call 24 hours a day, seven days a week, and smartphones mean that people cannot get away from work. The more constantly in touch we become, the more is expected of us in work . "

Article: This morning, a Virgin Atantin 747 Jumbo Jet became the first commercial airplane to fly on biofuel. The short flight from London to Amsterdam used a blend of 20% babassu oil mixed with 80% conventional jet fuel. What was really exciting about the flight was the fact that the engine did not have to be altered in any way for the biofuel to work While this is a great initial step in trying to reduce CO2(carbon-dioxide)emissions from airplanes. there are a lot of hurdles that still need to be overcome. First and foremost, unlike the normal fuel used to run airplanes (known as Jet A),biofuel freezes at high altitudes. Also, Jet'A'fuel burns consistently (at the same pace),which means it provides a safe and reliable fuel for long flights--engineers are not sure if biofuel will be able to do the same. The biggest hurdle to a full biofuel switch is our ability to be able to grow enough crops that can be converted to biofuel. There are two concerns that scientists have in this matter - the first is that the land to grow the extra crops will come from clearing more of our forests and the second is that since it competes with what we eat, the price of food will go up. However, Richard Branson of Virgin Airlines, envisions that if biofuel starts to replace oil on a greater basis, it will be manufactured from algae produced in sewage treatment plants, not from food sources. Birgin Airlines is not the only one trying to look for alternative fuel sources. Earlier this year, an Airbus A380 used another alternative fuel-a man-made mix of gas-to-liquid, in one of its four engines. The flight was tested by Rolls Royce (manufacturer of jet engines), in partnership with Shell (an oil company). Rolls Royce is also working with Air New Zealand on a similar project. While a complete switch to alternative fuel may take years, it is very encouraging to see airlines, oil companies and airplane manufacturers all coming together to try to make it happen!
Question: .Why does Virgin Airlines try to replace normal fuel with biofuel?
Options: (A) To cut down the flight cost of the company. (B) To remove some hurdles for the biofuel to work. (C) To reduce CO
2 emissions from airplanes. (D) To test plane engines on biofuel.

Article: "It was amazing, just impressive," Holly Budge, a 29-year-old British woman, said after making a safe landing at a spot 12,350 feet (3,765 meters) above sea level -- the highest "drop zone" achieved by a parachutist . "We had one minute of freefall and while we were above the clouds you could see Everest and the other high mountains popping out of the top," she said. Ms Budge and her two fellow daredevils, Wendy Smith, from New Zealand, and Neil Jones, from Canada, jumped out of an aircraft at about 29,500 feet, just higher than the peak of the world's highest mountain. They fell at speeds reaching 140mph, past the highest ridges of the snow-covering Himalayas, before each released a parachute . The jumpers wore oxygen masks to keep their lungs working as they fell. Wearing neoprene underwear was compulsory -- to prevent them from being frozen to death. The adventure, advertised by its organizers as "a feast for those who seek to stimulate all their senses to the full", appeared to have lived up to its billing. "I had never seen so many mountains before," Ms Smith said. "To be on top of the world was simply stunning ." The expedition also offered a way by which to celebrate her 30th birthday later this month, she said. Besides, her jump raised funds for charities in Britain and Nepal, including more than PS10,000 for the Hampshire Autistic Society. In the next few days the feat will be repeated by about 30 others, weather permitting. Each has paid at least PS12,675 to High and Wild, the British adventure travel company behind the project. Ms Budge said: "It was worth the money. It is something that has never been done before."
