PROBLEM: Article: They tell us when to get up or when we're running late for work and whether we are in danger of missing our favourite TV programme. But while our daily routines rely on clocks that tell us the time, science is discovering that our well-being is influenced by a very different kind of timepiece. Circadian rhythms---the human body's own internal clock---have a powerful influence on our health and behaviour. _ are programmed from birth and control functions ranging from temperature and blood pressure to sleep patterns. In recent years researchers have also discovered that this built-in mechanism can influence everything from the way we react to medicines to how well we learn music. The latest example, from experts at Harvard University in the US, shows that the human body clock can even dictate whether or not we are likely to tell the truth. Researchers found it was easier for people to fib in the afternoon because, as they were tired, the self control that would normally prevent them from lying started to break down. Tiredness made it harder to resist the temptation to tell lies---especially if it meant they got a financial reward at the end. "The body clock has a great effect on us all," says Professor Jim Horne from the Sleep Research Centre at Loughborough University. "Most people tend to feel good around late morning and then decline in the early afternoon. But the time most of us will feel our sharpest is between 6pm and 8pm. That's because sleepiness tends to build up throughout the day. By early evening our body clock kicks in to wake us up. One reason may be to ensure we get home safely. When our ancestors were coming home after hunting all day their internal clocks kicked in to get them home in one piece." So what effects do circadian rhythms have and what's the best time of day to take advantage of them?

PROBLEM: Article: Once upon a time the colors of the world started to quarrel. Green said, "Clearly I am the most important. I am the sign of life and hope. I was chosen for grass, trees and leaves. Look over the countryside and you will see that I am in the majority." Blue interrupted, "You only think about the earth, but consider the sky and the sea. It is the water that is the basis of life." Yellow chuckled . "The sun is yellow, as well as the moon and the stars. Every time you look at a sunflower, the whole world starts to smile." Red could bear it no longer. "I am the ruler of all of you. I am blood-life's blood! I am the color of danger and bravery. I bring fire into the blood. I am the color of passion and love." Purple stood at his full height. "I am the color of royalty and power. I am the sign of authority and wisdom. People do not question me! They listen and obey." Finally Indigo spoke with determination, "Think of me and I am the color of silence. I represent thought and reflection. You need me for balance and contrast , for prayer and inner peace." The colors went on boasting , each showing off his or her own advantages. Suddenlythere came a flash of bright lightening. Thunder rolled and boomed. Rain started to pour down. The colors were scared to death. In the midst of the quarrelling, rain began to speak, "You foolish colors. Don't you know that you were each made for a special purpose, unique and different? Join hands with one another and come to me." Doing as they were told, the colors united and joined hands. From then on, when it rains, colors will stretch across the sky in a great bow of color. Whenever a rainbow appears in the sky, let us remember to appreciate one another.
Question: Why did the colors quarrel?
Options: (A) Because they often fought for some reasons. (B) Because they were not liked by each other. (C) Because they all claimed to be the best. (D) Because they all wanted to rule other colors.

PROBLEM: Article: Their reunion was unlike any other. Graduating from the Macon, Georgia, class of 1959 gathered together in 2009, even though many of them never had an opportunity to meet during their high school days. Schools in the 1950's, like most other public locations, were segregated in Georgia. Kids were forced to attend different schools depending on the color1 of their skin, and those with white skin were further separated by gender. Fifty years later these people who were not allowed to associate with each other were finally able to connect. It all began with the personal journey of a man named Tom Johnson. He grew up in Macon and enjoyed a very successful career which included serving as the publisher of the Los Angeles Times and president of CNN. Tom's life changed drastically over the years, but he still felt the desire to reconnect with his roots. In 2005 Johnson returned to Macon with his son, Wyatt. As the pair drove around town, the father recounted high school stories to his son. He talked about how students attended one of three schools: BallardHudson, Lanier or Miller. Wyatt looked over at his father and said:"Dad think about how many friends you missed getting to know." Johnson thought about the people he never got the chance to meet. He decided to do something about it. The first step was to find people who graduated from all three schools. Johnson wrote to each person and proposed they all get together for a luncheon. He explained that even though they were kept apart during their youth, they didn't have to be separated any more. His classmates received the message with open hearts. A reunion date was set for October. More than 200 former Macon students traveled hundreds of miles to reunite with people who went to high school with them. It was an unprecedented event, former students coming together to make up for the time they had lost during the days of segregation.
