Read the following article and select the best answer. Article: The iPhone, the iPad, each of Apple's products sounds cool and has become a fashion. Apple has cleverly taken advantage of the power of the letter "i" -- and many other brands are following suit. The BBC's iPlayer -- which allows Web users to watch TV programs on the Internet -- adopted the title in 2008. A lovely bear -- popular in the US and UK -- that plays music and video is called "iTeddy". A slimmed-down version of London's Independent newspaper was launched last week under the name "i". In general, single-letter prefixes have been popular since the 1990s, when terms such as e-mail and e-commerce first came into use. Most "i" products are targeted at young people and considering the major readers of Independent's "i", it's no surprise that they've selected this fashionable name. But it's hard to see what's so special about the letter "i". Why not use "a", "b", or "c" instead? According to Tony Thorne, head of the Language Center at King's College, London, "i" works because its meaning has become ambiguous. When Apple uses "i", no one knows whether it means Internet, information, individual or interactive, Thorne told BBC Magazines. "Even when Apple created the iPod, it seems it didn't have one clear definition," he says. "However, thanks to Apple, the term is now associated with portability ."adds Thorne. Clearly the letter "i" also agrees with the idea that the Western World is centered on the individual. Each person believes they have their own needs, and we love personalized products for this reason. Along with "Google" and "blog", readers of BBC Magazines voted "i" as one of the top 20 words that have come to define the last decade. But as history shows, people grow tired of fads . From the 1900s to 1990s, products with "2000" in their names became fashionable as the year was associated with all things advanced and modern. However, as we entered the new century, the trend eventually disappeared. Question: Nowadays, the "i" term often reminds people of the products which are _ . - environmentally friendly - advanced - recyclable - portable
portable

Read the following article and select the best answer. Article: Like distance runners on a measured course,all of us will move through time in a roughly predictable pattern. In the first stage of our lives,we develop and grow, reaching toward the top of physical vitality . After we grow up,however, the body begins a process of gradually wearing out. A new awareness of physical fitness may help lengthen our years of health and vitality,yet nothing we do will work to stop the unavoidable force of aging. Most of the changes of aging take place deep inside the body.The lungs become less able to take in oxygen.Powerful muscles gradually lose their strength.The heart loses power and pumps less blood.Bones grow easier to break. Finally, we meet a stress,a stress that is greater than our physical resistance.Often,it is only a minor accident or chance infection(a disease caused by virus),but this time, _ brings life to an end. In 1932,a classic experiment nearly doubled the lifetime of rats,simply by cutting back the calories in their diet The reason for the effect was then unknown. Today, at the University of California at Berkley, Dr.Paul Seagle has also greatly lengthened the normal lifetime of rats.The result was achieved through a special protein limited diet,which had a great effect on the chemistry of the brain.Seagle showed that within the brain,specific chemicals control many of the signals that influence aging.By changing that chemical balance,the clock of aging can be reset. For the first time, the mystery of why we age is being seriously challenged.Scientists in many fields are now making striking and far-reaching discoveries. An average lifetime lasts 75 years,yet in each of us lies a potential for a longer life.If we could keep the vitality and resistance to disease that we have at age twenty, we would live for 800 years. Question: Which of the following is not a change of aging? - People gradually lose their muscle strength. - Bones tend to break more easily. - The heart loses power and pumps less blood. - The lungs become unable to take in oxygen.
(Answer)
The lungs become unable to take in oxygen.

Ques:Read the following article and select the best answer. Article: WASHINGTON---At least four more U.S. air-traffic controllers are caught nodding off on the job at three separate airports across the nation, the government said Wednesday. The controller working alone in the tower fell asleep and was out of communication for 16 minutes while a medical flight carrying a patient was trying to land at about 2 A.M. Wednesday at Reno-Tahoe International Airport in Nevada, the Federal Aviation Administration (FAA) said in a statement. The FAA announced that it is also investigating a controller who fell asleep Monday at Boeing King County International Airport in Seattle and two controllers who were unresponsive at Preston Smith International Airport in Lubbock, Texas, on March 29.The agency had earlier revealed that an air-traffic supervisor fell asleep March 23 at Ronald Reagan Washington National Airport and a controller slept for five hours at McGhee Tyson Airport in Knoxville, Tennessee on Feb.19. "I am sick of this," Senate Commerce, Science and Transportation Chairman Jay Rockefeller, a West Virginia Democrat, said in a statement. "We can't have an aviation system where some of the people responsible for safety are asleep at the switch." As the incidents pile up, sleep experts say it demonstrates that the agency faces a systemic issue with the thousands of people expected to work through the night in safety-critical jobs. Scientific research shows that workers on midnight shifts make more errors because it is so difficult for the body to adapt to sleeping during the day, they say. ks5u The agency will add an extra controller at the 27 towers staffed with one worker on the midnight shift, the FAA statement said. Agency chief Randy Babbitt and the controllers' union president, Paul Rinaldi, will visit facilities around the country next week to reinforce the need for "the highest professional standards," according to the FAA. Doug Church, a spokesman for Rinaldi of the National Air Traffic Controllers Association, didn't immediately return a telephone call for comment.... Question: We can infer from the passage that _ . - The controllers were working alone while they were on duty - The incidents are rooted in fatigue problems and those on midnight shifts need an extra nap - In the U.S. , thousands of people expect to work through the night in safety-critical jobs - The agency has added an extra controller at the 27 towers

Ans:
The incidents are rooted in fatigue problems and those on midnight shifts need an extra nap
