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: Some people make art with paint, and others use pencil or clay. But Italian artist Maurizio Savini prefers to use bright pink gum--after it has been chewed. Savini makes huge sculptures of bears and even people out of used chewing gum. Each sculpture requires thousands of pieces of gum. "I like to use chewing gum because it seemed to me a material that can be used in many ways compared with those used by the conventional arts such as painting," Savini says. How does he do it? The process is a lot like working with clay. "I work the chewing gum when it is warm and shape it with a knife," says Savini. Then, he puts a chemical onto each gum sculpture to make the gum stay in place. Savini's sticky art has been shown in cities like London, Paris, and Rome, where he lives today. Savini isn't the only artist to work with gum. His pink sculptures have inspired artists all over the world to get creative with the sticky matter. London artist Ben Wilson paints small paintings onto flat pieces of chewed gum he finds stuck to streets and sidewalks. In Canada, Jason Kronenwald uses different colored gum to make portraits of famous people. Kronenwald seldom chews gum himself. Instead, his friends help chew gum for him while he's working. "At times it can make me _ , but I just pay attention to the colors I need and get the sculpture going," he says. In America, Jamie Marraccini's art depends on color, so he tests different kinds of gum before using them. To find out what color the chewed gum will become once hardened, he lets it age for up to six months. "I've created 30 works totaling more than 35,000 pieces of gum," says Marraccini. That's a lot of gum! So think twice the next time you throw away a wad of gum. Maybe what seems like trash could actually be the beginning of a great piece of art.
Question: Marraccini stores the gum for six months in order to _ .
Options: (A) judge how hard it will be (B) know whether it is still sweet (C) examine what chemicals it contains (D) see what color it will become
