Researchers around the world have been trying their hand at making better use of the huge amount of wind energy available in nature to produce clean energy. Apart from this, studies are being carried out to harness  usable wind energy produced by man-made technologies. One useful source identified by Indian inventor Santosh Pradhan about two years ago is a speeding train, which produces fierce wind that can be transformed into electricity. According to Pradhan's proposal, with a few small improvements in existing trains running in Mumbai, the largest city in India, at least 10,000 megawatts  of electricity could be harvested each day. Building on this principle, designers Ale Leonetti Luparinia and Qian Jiang from Yanko Design have created a device  called T-Box that harnesses wind energy from speeding trains. T-Box can be placed within the railway tracks. It is half-buried underground between the concrete sleepers , which does not disturb the normal train operating at all. According to Yanko, around 150 T-Boxes can be fitted along a 1,000-meter railway track. A train running at a speed of 200 kph can produce winds blowing at 15 miles a second. Based on this calculation, 150 T-Boxes can produce 2.6 KWH of electricity per day. The T-Box's design won a silver medal in last year's Lite-On Awards and was exhibited last summer at the Xue Xue Institute in Taipei, Taiwan Province. Though the figures look impressive, it is important to remember that the design is still at a conceptual stage and hasn't taken into account issues such as pieces of waste material produced by the device and the efforts and costs involved in the maintenance  of the device. We can expect the technology to see the light of the day only after it clears these issues. If so, rail travel, one of the greenest forms of travel, will become greener and more energy-efficient. How much electricity can be produced per day by T-Boxes along a railway track of 100km? A) 260 KWH. B) 2.6 KWH. C) 150 KWH. D) 1.5 KWH.

We start finding things laughable -- or not laughable -- early in life. An infant first smiles at approximately eight days of age. In his book Beyond Laughter, psychiatrist Martin Grotjahn says that the earlier infants begin to smile and laugh, the more advanced their development is. Studies revealed   that children who did not develop these responses "developed a schizophrenic psychosis   in later life, or simply gave up and died". Between the ages of six months and one year, babies learn to laugh for essentially the same reasons why they will laugh throughout their lives, says Dr. Jacob Levine. He says that people laugh to express mastery over an anxiety. Adult laughter is more subtle  , but we also laugh at what we used to fear. The feeling of achievement, or lack of it, remains a leading factor. Giving a first dinner party is an anxious event for newly-weds. Will the food be good? Will the guests get along? All goes well; the party is over. Now they laugh freely. Their pleasure is from recalling the evening's activities. They couldn't enjoy the second pleasure without the first. Laughter is a social response caused by signals. Scientists have not determined a brain center for laughter, and they are puzzled by patients with certain types of brain damage who go into laughing with no apparent reason. The rest of us require company and a reason to laugh. Another reason why laughter is pleasurable is because of the physical feeling involved. According to Dr. Levine, we can measure our adjustment to the world by our capacity   to laugh. When we are secure about our abilities, we can make fun of our weakness. If we can laugh through our anxieties, we will not be overpowered   by them. The ability to laugh starts early, but it takes a lifetime to perfect. Says Dr. Levine, "When social relationships are mastered, when individuals have mastered... a peaceful relationship with themselves, then they have ... the sense of humor." And then they can throw back their heads and laugh. The infant who begins to smile or laugh early will   _  . A) become a more subtle laughter when he or she grows up B) be more likely to take a whole life to perfect smiling and laughing C) have more advantages of development in growth and health D) suffer from schizophrenic psychosis and even die in later life

For years I wanted a flower garden.But then we had Matthew.And Marvin.And the twins, Alisa and Alan.And then Helen.Five children.I was too busy raising them to grow a garden. Money was tight, as well as time.Often when my children were little, one of them would want something that cost too much, and I' d have to say, "Do you see a money tree outside? Money doesn't grow on trees, you now." Finally, all five got through high school and college and were off on their own. One spring morning, on Mother's Day, I was working in my kitchen.Suddenly, I realized that cars were tooting their horns as they drove by.I looked out the window and there was a new tree, planted right in my yard.I thought it must be a weeping willow, because I saw things blowing around on all its branches.Then I put my glasses on-and I couldn't believe what I saw. There was a money tree in my yard! I went outside to look.It was true! There were dollar bills, one hundred of them, taped all over that tree.Think of' all the garden flowers I could buy with one hundred dollars! There was also a note attached: ''IOU eight hours of digging time.Love, Marvin." Marvin kept his promise, too.He dug up a nice ten-by-fifteen foot bed for me And my other children bought me tools, ornaments , a trellis , a sunflower stepping stone and gardening books. That was three years ago.My garden's now very pretty, just like I wanted.When I go out and tend my flowers, I don't seem to miss my children as much as I once did.I feel like they're right there with me. I'm still not sure that money grows on trees.But I know love does! Which of the following would be the best title for the text?    _  . A) My Money Tree B) The Garden of My Children C) Mother's Love D) Marvin's Promise
