[Q]: Article: The following are letters to the editor of a school newspaper Dear editor, I'd like to express my opinion about grades. Students should be allowed to study without worrying about grades. Fortunately, most educators are becoming aware of the fact that students have different interests and abilities. I understand that grades are useful, but grades often limit creativity. Competing for better grades causes many students to turn down opportunities to pursue music, dramatics and sports. Grades force an arbitrary standard of success on everyone. I do not demand as some extremists do, that grades be removed immediately. However, I do believe that less emphasis should be placed on grades. I hope that someday grades will become optional at Village High School. Magdalena Smith Drama Club Dear editor, I'd like to say something about grades. Let's face the facts about grades. Grades perform three basic functions. First, grades motivate students to work at their highest level of competence. Second, they act as a reward for hardworking students and as a punishment to students who do not work hard. Finally, grades are used as an effective standard by which to measure student achievement. Good grades help students to get jobs and to get into university. I've spoken with a number of students who have jobs, and most of them say that they were hired primarily on the basis of their grades. My grades helped me land a part-time job and will help me get into university next year. I think grades are extremely important at Village High School. Simon Harper Science Club

[Q]: 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

[Q]: Article: Mark Rothko, one of the greatest painters of the twentieth century, was born in Daugavpils, Latvia in 1903. His family immigrated to the United States in 1913, after a 12-day voyage. Mark moved to New York in the autumn of 1923 and found employment in the garment trade and settled down on the Upper West Side. It was while he was visiting someone at the Art Students League that he saw students painting a model. According to him, this was the start of his life as an artist. He was twenty years old and had taken some art lessons at school, so his initial experience was far from an immediate calling. In 1936, Mark Rothko began writing a book, which he never completed, about the similarities in the children's art and the work of modern painters. The work of modernists, which was influenced by primitive art, could, according to him, be compared to that of children in that "Child art transforms itself into primitivism, which is only the child producing a copy of himself." In this same work, he said that "The fact that one usually begins with drawing is already academic. We start with colour." It was not long before his multiform developed into the style he is remembered for. In 1949 Rothko exhibited these new works at the Betty Parsons Gallery. For reviewer Harold Rosenberg, the paintings were unique and primitive. Rothko had, after painting his first multiform, separated himself from the world in East Hampton on Long Island, only inviting a very few people, including Rosenberg, to view the new paintings. The discovery of his works' specialty came at a period of great sorrow: his mother Kate died in October 1948. As part of this new uniformity of artistic vision, his paintings no longer had individual titles. From this point on they were simply untitled, numbered or dated. However, to assist in distinguishing one work from another, traders would sometimes add the primary colours to the name. Additionally, for the next few years, Rothko painted in oil only on large vertical tents. This was done to surround the viewer, or, in his words, to make the viewer feel enveloped within the picture.
Question: What did Rothko think of modern art?
Options: (A) It could be produced by children. (B) It could be compared to child work. (C) It was a certain kind of primitive art. (D) It was academic from the very beginning.
