[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
[A]: A

[Q]: Article: Last August, Joe and Mary Mahoney began looking at colleges for their 17-year-old daughter, Maureen. With a checklist of criteria in hand, the Dallas family looked around the country visiting half a dozen schools. They sought a university that offered the teenager's intended major, one located near a large city, and a campus where their daughter would be safe. "The safety issue is a big one," says Joe Mahoney, who quickly discovered he wasn't alone in his worries. On campus tours other parents voiced similar concerns, and the same question was always asked: what about crime? But when college officials always gave the same answer -----"That's not a problem here,"-----Mahoney began to feel uneasy. "No crime whatever?" comments Mahoney today. "I just don't _ it." Nor should he: in 1999 the U.S. Department of education had reports of nearly 400,000 serious crimes on or around our campuses. "Parents need to understand that times have changed since they went to college," says David Nichols, author ofCreating a Safe Campus. "Campus crime mirrors the rest of the nation." But getting accurate information isn't easy. Colleges must report crime statistics by law, but some hold back for fear of bad publicity , leaving the honest ones looking dangerous. "The truth may not always be serious," warns S. Daniel Carter of Security on Campus, Inc., the nation's leading campus safety watchdog group. To help concerned parents, Carter promised to visit campuses and talk to experts around the country to find out major crime issues and effective solutions.
Question: It is often difficult to get correct information on campus crime because some colleges _ .
Options: (A) receive too many visitors (B) mirror the rest of the nation (C) hide the truth of campus crime (D) have too many watchdog groups
[A]: C

[Q]: Article: Vampires , creatures of myth, have been around in one form or another for centuries. Terrifying but also attractive, they are as popular in the early 21st century as ever, as the current popularity of Twilight series, and its hero Edward Cullen, show. Vampires first appeared in fiction in the 1700s; in 1895 Irish novelist Bram Stoker published Dracula, introducing the world's most famous vampire. But just what is it about these drinkers of human blood that continues to fascinate us? Speaking to Eric Lewis of the Times and Transcript website, academic Deborah Wells said that vampires are "culturally adaptive ". "We create very different vampires to fit different times. Edward Cullen is not the same as Count Dracula," she said. Different as they are, Wells believes vampires are "the perfect containers into which we can pour our current cultural anxieties". Bram Stoker's Dracula is powerful, yet old and physically ugly. Stoker's book dealt with fear of the fall of the British Empire, real fears in the day in which it was written. According to the website Bookpages, today's vampires have all our cultural desires, money, power and sexual attraction. Represented by Cullen, they are noble, handsome young men whom women find irresistible . What's more, vampires challenge traditional ideas about death, science and parental authority . This may be why teenagers are drawn to vampire tales. "In many ways, the vampire story shows up teenage concerns," said Wells. "The emotional intensity of the relationship with the vampire matches the intensity of how it feels to have your first real love affairs. Your first real love, it really feels like life and death."
Question: What is the vampire like in Bram Stoker's book?
Options: (A) Anxious but perfect. (B) Afraid of the fall of the British Empire. (C) Terrifying but also attractive. (D) Powerful, old and ugly.
