Geena David knew she wanted to be a movie star when she was very young. She was not sure what gave her the idea, but she wanted to look like a movie star. "I have a lot of pictures from my childhood of me wearing sunglasses," she says. "I used to wear them to watch TV." Early movie actors started wearing sunglasses not because they looked good, but because their eyes hurt. The lights used on movie sets were extremely bright and could cause a painful problem known as "Klieg eyes". It was named after the Klieg brothers who invented the lights. Actors wore sunglasses to give their eyes a rest. But when movie stars began wearing their sunglasses in public, they quickly became a must. Eventually actors started wearing sunglasses in their movies as well as on the street. Audrey Hephburn wore ultra-cool Ray-Ban sunglasses in the 1961 movie, Breakfast at Tiffany's. As a result, Ray-Ban sunglasses started to appear more and more in the movies. In 1979, Ray-Ban "Wayfarers" were worn by Jake and Elwood in The Blue Brothers. Tom Cruise wore Ray-Ban "Aviator" sunglasses in the 1986 hit, Top Gun. Then in 1997, Will Smith and Tommy Lee Jones made Ray-Ban "Predator" sunglasses famous in Men in Black. Of course sunglasses aren't just a fashion statement. The main reason to wear sunglasses is to protect our eyes against UV radiation. UV radiation can damage our eyes, so people now choose their sunglasses carefully. But you don't have to give up style for safety. The choice of frames and lenses available these days is huge. So you can protect your eyes and still be the coolest person on the beach. Why did Geena David like to wear sunglasses? A) She wanted to follow a movie star. B) She was a movie star. C) Wearing sunglasses was good to her eyes. D) It was good to wear sunglasses when watching TV.

Learning disabilities are very common. They affect perhaps 10 percent of all children .Four times as many boys as girls have learning disabilities. Since about 1970, new research has helped brain scientists understand these problems better. Scientists now know there are many different kinds of learning disabilities and that they are caused by many different things. There is no longer any question that all learning disabilities result from differences in the way the brain is organized. You cannot look at a child and tell if he or she has a learning disability .There is no outward sign of the disorder .So some researchers began looking at the brain itself to learn what might be wrong. In one study ,researchers examined the brain of the learning-disabled person who had died in an accident .They found two unusual things. One has something to do with cells on the left side of the brain ,which control language. These cells normally are white .In the learning-disabled person, however ,these cells were gray. The researchers also found that many of the nerve cells were not in a line the way they should have been .The nerve cells were mixed together. The study was carried out under the guidance of Norman Geschwind, an early expert on learning disabilities. Doctor Geschwind thought that learning disabilities resulted mainly from problems on the left side of the brain .He believed this side of the brain failed to develop normally .Probably ,he said ,nerve cells there did not connect as they should .So the brain was like an electrical device in which the wires were crossed. Frank Duffy experimented with this technique at Children's Hospital Medical Center inprefix = st1 /Boston. Doctor Duffy found large differences in the brain activity of normal children and those with reading problems. The differences appeared throughout the brain. Doctor Duffy said his research proves that reading disabilities result from damage to a wide area of the brain, not just the left side. Doctor Duffy believed that the problem of learning disabilities_. A) was limited to the right side of the brain B) was not limited to the left side of the brain C) resulted from the left side of the brain D) did not lie in the left side of the brain

Ques: April 2009, in the state of Georgia, USA, twenty thousand people watched high school students from twenty- eight countries compete with robots they had built. More than ten thousand students and more than five hundred robots took part in the competition. Almost 1,700 high school teams took part in the competition called LUNACY. In January, the organization sent the same robots to each team. The teams had six weeks to build robots that could compete in the LUNACY game. The playing area consisted of six robots, three on each team. Each robot had a trailer connected to it. The robots had to pick up large balls and throw them into the trailers of opposing robots. The robots were moving on a platform where they could move smoothly. A team from the USA won the LUNACY competition. American inventor Dean Kamen started the competition in 1989 to increase young people's interest in science and technology. The organization holds robotic competitions around the world. It offers programs that help young people learn about science, technology, engineering and maths, and at the same time build life skills. Many companies provide support for the organization. Mr. Kamen says the goal is more than building robots. He says the student competitors showed they could solve difficult technological problems and, he says that it is good news because the world needs creative thinkers to solve the increasingly difficult problems of the future. In order to win the LUNACY competition, the robots need to _ . A) have the most trailers connected to them B) throw the most balls into the trailers of the opposing robots C) stand still when throwing balls D) move the trailers as fast as possible to get the balls
Ans: B
Question: What is the nature of the scientific attitude, the attitude of the man or woman who studies and applies physics, biology, chemistry, geology, engineering, medicine or any other science? We all know that science plays an important role in our societies. However, many people believe that our progress depends on two different aspects of science. The first aspect is the application of the machines, products and systems of knowledge that scientists and technologists develop. The second is the application of the special methods of thought and action that scientists use in their work. What are these special methods of thinking and acting? First of all, it seems that a successful scientist is curious - he wants to find out how and why the universe works. He usually pays attention to problems which he notices have no satisfying explanation, and looks for relationships even if the data available seem to be unconnected. Moreover, he thinks he can improve the existing conditions and enjoys trying to solve the problems which this involves. He is a good observer, accurate, patient and objective and uses the facts he observes to the fullest. For example, trained observers obtain a very large amount of information about a star mainly from the accurate analysis of the simple lines that appear in a spectrum . He does not accept statements which are not based on the most complete evidence available. He rejects authority as the only basis for truth. Scientists always check statements and make experiments carefully and objectively. Furthermore, he does not readily accept his own idea, since he knows that man is the least reliable of scientific instruments and that a number of factors tend to disturb objective investigation. Lastly, he is full of imagination since he often has to look for relationships in data which are not only complex but also frequently incomplete. Furthermore, he needs imagination if he wants to guess how processes work and how events take place. These seem to be some of the ways in which a successful... Which word can be used to describe the data that a good scientist uses? A) complete B) objective C) complicated D) accurate
