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: Computer power is moving into the "cloud"--networks of data centres that use the Internet to supply all kinds of services, from e-mail and social networks to data storage and analysis. The rise of cloud computing is rapid and causing huge changes in the tech industry. The old guard is suffering: this week's $67 billion merger   between Dell and EMC, makers of computers and storage devices respectively  , was a marriage forced by the rise of the cloud. Disruptive   newcomers are blooming: if Amazon's cloud-computing unit were a stand-alone public company, it would probably be worth almost as much as Dell and EMC combined. The gains for customers have been equally dramatic. Compared with older IT systems, cloud computing is often much cheaper. It adds tremendous flexibility: firms that need more computing capacity no longer have to spend weeks adding new servers and installing software. In the cloud they can get hold of it in minutes. Their applications can be updated continually, rather than just every few months. Individual users can reach their e-mails, files and photos from any device. And cloud services also tend to be more secure, since providers know better than their customers how to protect their computing systems against hackers. But cloud computing makes one problem worse. In the old IT world, once a firm or a consumer had decided on an operating system or database, it was difficult and costly to switch to another. In the cloud this "lock-in" is even worse. Cloud providers go to great lengths to make it easy to upload data. They accumulate huge amounts of complex information, which cannot easily be moved to an alternative provider. Cloud firms also create a world of interconnected services, software and devices, which is convenient but only for as long as you don't venture   outside their universe. Being locked in to a provider is risky. Firms can start to tighten the screws by increasing prices. If a cloud provider goes bust  , its customers may have trouble getting back their data. These risks have already caused a debate about whether the cloud needs stricter regulation. Some European politicians want to force cloud providers to ensure that data can be moved between them. That is too heavy-handed, because strict rules will inhibit   innovation in what is still a young industry. The history of computing suggests that common standards may well appear naturally in response to customers' demands--just as in personal computers, where it is now much easier to use the same files on different systems. In the meantime, a few commonsense measures can reduce the risk of lock-in. Firms that use more than one cloud provider to host their data are less affected. So are those that keep their most important information in their own data centres. Consumers can take precautions, too. Some services are better than others at enabling users to move data between providers (Google does well on this score). Cloud computing promises its users many benefits, but don't mistake it for some sort of digital heaven. 
 Question: The author takes "the merger between Dell and EMC" for example to show   _  . 
 Options: (A) the influence of cloud computing on computer and storage device makers (B) the miserable sufferings of old computer companies (C) the rapid development of new computer companies (D) the interaction between old companies and newcomers

Article: Letters to the next president Dear Mr. President: I would like to personally thank you for your time and concern for our great country. I would like to take a few minutes to address a few concerns that I have with the United States. First of all, I would like to address the war. In my opinion, we should have never been involved with Iraq to the extent that we are now. I believe we should pull our troops out. However, I think there should be a time table that we follow but the time table should not be released  because the enemy does not need to know when we are going to pull out. Also, the war takes out a ton of our money, which leads me to my next issue. The economy right now, in the opinion of many Americans is the biggest issue with which we are facing right now. No one can predict what will happen one day or the next. The obvious thing to do is to put 700 billion dollars in the economy, but that bill failed and was rejected by the House of Representatives . Instead of putting 700 billion dollars in, I think the money should be equally distributed among Americans to pay off their debts. I'm not sure if this would work, but I think it is a positive alternative  we could take. My final issue I would like to call to your attention is teacher's salaries. The high school students of today are America's future. In a way, America's future depends greatly on the high school teachers of America. Saying this, it is sad that teacher's salaries are where they are. While teachers are working harder and harder every day to teach high school students, CEO's of big companies that are driving our countries economy into the ground are getting bonuses. I'm not saying that teacher's salaries should be the same of CEO's of companies, but I do strongly believe that action should be taken to increase the salaries of teachers because they have one of the most important jobs in America - - preparing our country for the future. Once again, thank you for your time and your effort you put in to making this great country a better place. Sincerely, Walker
