Read the following article and select the best answer. Article: The next time you get caught jumping on your bed you can tell your parents with a straight face that you are not playing, simply getting ready got a promising career in "Mattress Jumping". Believe it or not, there are some people who actually get paid to do that! According to Reuben Reynoso, a professional mattress tester at San Francisco's McRoskey Mattress Factory that still makes every mattress by hand, it is real work and needs some training. For a start, it's not all about jumping to new heights or doing tricks like professional athletes, but rather about feeling each area of the mattress carefully to detect the filling. In order to do it right, every bit of the mattress has to be tested slowly and deliberately. Over the years, Reynoso has figured out the perfect routine. He begins by placing a protective mat over the mattress so that it doesn't get dirty or absorb the smell from his feet. Then begins the fun---he steps to the middle of an edge and then takes five steps back and five steps forward. In this way, he slowly but surely, covers the entire surface. The key according to him is to find the perfect number of jumps---Too many and he will end up destroying the mattress completely. Too few? And it will not fit into the giant machine for that final sewing! Who knew a job that sounds so simple could have so many skills! While Reuben will not reveal how he got into this profession, he will admit that it is more fun than being a carpenter, roofer, construction worker and railroad engineer---all jobs he has tried previous to finding his true profession! Question: We learn from the text that the McRoskey Mattress Factory _ . - is the world's oldest mattress factory - make mattresses for sports - produces mattresses by hand - hires athletes as mattress testers

Ques: Read the following article and select the best answer. Article: Why did the chicken cross the road? To get to the other side. Most people know this joke. But recently, some people have been much more worried about how the grizzly bear and mountain lion can cross the road. " Millions of animals die each year on the U. S. roads, " the Federal Highway Administration reports. In fact, only about 80 ocelots , an endangered wild cat, exist in the U. S. today. The main reason? Roadkill. "Eco-passages" may help animals cross the road without being hit by cars. They are paths both over and under roads. " These ecopassages can be extremely useful,so that wildlife can avoid road accidents ," said Jodi Hilty of the Wildlife Protection Society. But do animals actually use the eco-passages? The answer is yes. Paul Beier of Northern Arizona University found foot marks left by mountain lions on an eco-passage that went under a highway. This showed that the lions used the passage. Builders of eco-passages try to make them look like a natural part of an area by planting trees on and around them. Animals seem to be catching on. Animals as different as salamanders and grizzly bears are using the bridges and underpasses. The next time you visit a park or drive through an area with a lot of wildlife, look around. You might see an animal over-pass ! Question: The writer uses the example of "ocelots" to show that _ . - an increasing number of animals are killed in road accidents - the driving conditions have improved greatly - the measure for protecting wildlife fails to work - wild animals have become more dangerous

Baroness Tarot, an Oxford University neuroscientist believes repeated exposure could rewire the brain.Computer games and fast-paced TV shows were also a factor, she said."My fear is that these technologies are weakening the brain to the state of small children who are attracted by buzzing noises and bright lights, who have a small attention span and live for the moment." "I often wonder whether real conversation in real time may eventually give way to these easier and faster screen dialogues, in much the same way as killing and butchering an animal to eat has been replaced by the convenience of packages on the supermarket shelf," she said. Psychologists have also argued that digital technology is changing the way we think.They point out that students no longer need to plan their term papers before starting to write--thanks to word processors they can edit as they go along. A study by the Broadcaster Audience Board found teenagers now spend seven and a half hours a day in front of a screen.Educational psychologist...
