Ques: I'm taking a test and have to guess the right answer to the question after the article. Article: You either have it, or you don't-- a sense of direction, that is. But why is it that some people could find their way across the Sahara without a map, while others can lose themselves in the next street? Scientists say we're all born with a sense of direction, but it is not properly understood how it works. One theory is that people with a good sense of direction have simply worked harder at developing it. Research being carried out at Liverpool University supports this idea and suggests that if we don't use it, we'll lose it. "Children as young as seven have the ability to find their way around," says Jim Martland, Research director of the project. "However, if they are not allowed out alone or are taken everywhere by car, they never develop the skills." Jim Martland also emphasizes that young people should be taught certain skills to improve their sense of direction. He makes the following suggestions: If you are using a map, turn it so it relates to the way you are facing. If you leave your bike in a strange place, put it near something like a big stone or a tree--something easy to recognize. Note landmarks on the route as you go away from your bike. When you return, go back along the same route. Simplify the way for finding your direction by using lines such as streets in a town, streams, or walls in the countryside to guide you. Count your steps so that you know how far you have gone and note any landmarks such as tower blocks or hills which can help to find out where you are. Now you will never get lost again! Question: What is TRUE of 7-year-old children according to the passage? Options: A: They never have a sense of direction without maps. B: They should never be allowed out alone if they lack a sense of direction. C: They have a sense of direction and can find their way around. D: They can develop a good sense of direction if they are driven around in a car.
Ans: B

Ques: I'm taking a test and have to guess the right answer to the question after the article. Article: Movie fans know that their action hero Superman does not really fly.And, in the movie Superman Returns, another visual trick is played on viewers.The man they see flying is not real.He is what is called a virtual actor.The first step in creating this digital actor is to have a real person stand in a room called a light stage.A computer then captures the outlines and shapes of his face and records how they throw off light .Paul Debevec is with the Institute for Creative Technologies at the University of Southern California. "We can light them with very specially computer-controlled illumination and take photos of them from seven different viewpoints with high quality digital still cameras." Mr.Debevec is part of a team working to create computerized images of people, objects and environments that look and act real.The light stage permits actors to be turned into digital versions of themselves much like the blue creatures in the movie Avatar.The real world could soon be using a similar technology.Computer experts at the Institute are developing a 3-D video teleconferencing system.It would send a video image of a person into a meeting room.That image would be able to work with the people in the room, who would see it in 3-D without special eyeglasses.Paul Debevec says: "The person who is being transmitted to a remote location can actually look around at the people in the room and everybody in that room knows who they're looking at .And that's such a fundamental part of human communication." He believes the business world will begin to use3-D video teleconferencing in the next five years." It's also a medium with which young people today are particularly comfortable," he said.A demonstration of an interaction between an earthquake survivor and students may be possible in a year.In 10 years, we may be able to play 3-D video games without special glasses. Question: What is the author's attitude towards 3D technology? Options: A: Cautious. B: Positive C: Skeptical D: Critical.
Ans: B

Ques: I'm taking a test and have to guess the right answer to the question after the article. Article: Is it okay to keep exercising when you have a cold? What about the flu? With winter viruses going around, it's important to know how to alter your training if you do catch a germ or two. "The guidelines are pretty easy," says Dr Lorenzo Masci from the Alphington Sports Medicine Clinic. "Anything above the neck --- so if you've got a cold for example, a runny nose or a sore throat --- then you should probably cut down your exercise by half and do 50 percent of what you normally do." "If you've got anything below the neck, like muscle pain, joint pain or fever, you shouldn't really exercise at all until those general symptoms settle down," Lorenzo says. He points out that a cough would also fall into this more serious category. "For example, if anyone comes in with a fever and a runny nose, I'd tell them to stop exercising until the fever and the muscle ache settles. Then they can start their training again at 50 percent once all those symptoms settle, even if they've got a bit of a runny nose or a sore throat." "The reason we tell people to stop exercising is because if you exercise when you're unwell it can make the illness worse and prolong it." There is a second reason Lorenzo advises his patients to stop exercising when they have "below the neck" symptoms. In the event you have an illness which affects your heart, exercise can sometimes actually lead to death. Lorenzo advises to take zinc and vitamin C as a way of preventing colds. But he admits that this is controversial --- some studies have shown that these supplements can improve immune function while other studies have cast doubt on the issue. The good news is that if you exercise regularly, you're likely to improve your immune function. "If you exercise too much, it can predispose you to coughs and sniffles," he points out. This is often the case for excellent athletes who train every day, such as triathletes . "But what we do know is that if you exercise at a moderate level, your immune system improves such that you're probably at a lower risk... Question: How should people do exercises with a fever or a cough? Options: A: They should probably reduce their training time by 50%. B: They should stop exercising until they recover. C: They should start exercising at 50% after their runny nose settles. D: They should do half of what they normally do.
