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.

Article: As a school teacher, Inderjit Khurana used to take the train to work. And one day, at the station, she saw dozens of children who spent their days begging from train passengers rather than going to school. She learned that it was not a rare problem and that millions of children in India lived on the streets. Realizing that these children would never be able to escape poor life and homelessness without education, and that it would be impossible to send these children to school, Inderjit decided to create a model program---taking the school to the most out- of-school children. Khurana's train platform schools aim to provide a creative school form and give children the basic levels of education. Her last goals reach far beyond the 20 platform schools she and her colleagues have created in India's Bhubaneswar region. She is determined that her program will become a model for changing the lives of the poorest children throughout India and the world. Khurana founded the Ruchika Social Service Organization(RSSO) in 1985. The teachers gather the children together between the stops of the train for reading, writing, maths and history taught through songs and other teaching tools. Khurana recently comes to realize that the education of these children is impossible when the most basic needs of their families are not being met. So she also provides food and medicine for their families. Khurana insists that every child have the right to an education and that if a child cannot come to the school, then the school must come to him or her.
Question: Khurana's final aim is to _ .
Options: (A) make the poorest children's lives better (B) put an end to the problem of children's dropout (C) attract more students to her platform schools (D) set up 20 platform schools throughout India

Article: Every year seals would crowd ashore in Farne Island and give birth to their pups. Between early October and early December, 1,500 seal pups will be born. Almost half of them will not make it past the first three weeks of life. "The pups have to stay out of the water for the first three weeks, when they have their white coat, which is not very waterproof," explains the warden ,who spends nine months on the Island. "But when you're born in November on a rock in the North Sea, it's a tough start to life," he said. Storms often wash young pups into the water. And occasionally, young, inexperienced mothers abandon their pups and head out to sea. "We lost 41% last year," said David Steel, the National Trust's head warden on the Farne Islands. "Mother Nature certainly keeps them in check." Despite the early challenges for every newborn seal, the population is healthily and slowly and steadily growing. There are almost 4,000 seals on a set of islands, which is named a Special Area of Conservation(SAC), meaning it is protected under EU regulations. This successful human safeguarding of the seals' habitat is huge turnaround . Just a few decades ago, the seal population was deliberately _ The animals used to be thought of as a threat to local fish stocks. During the late 1960s and 1970s, thousands of seals were shot in a cull that aimed to protect the local fishing industry. According to the National Trust, between 1962 and 1983 approximately 2,000 adult females and 3,000 pups were shot. But, as the fishing industry collapsed, it was gradually replaced by tourism. Today, several companies use fishing boats to take groups of people to visit the islands and admire the scenery, seabirds and, of course, the seals that make their homes in this bleakly beautiful place.
Question: In the first three weeks after they were born, almost half of the seal pups _ .
Options: (A) would be abandoned by their mothers (B) would be protected by the wardens (C) couldn't live independently (D) would die mostly in the sea water.
