Article: Seven tips to good table manners Whether it's a dinner at a friend's house or a business meeting over lunch, we judge people based on their table manners. But what can you do if your kids do not behave themselves at the dinner tables? The following are seven tips to set your children on the road to good table manners: *Look for the good. Instead of pointing out all the things your children do wrong, point out what they do right. Please say, for example, "I am so proud of you. It was wonderful the way you served yourself." *Don't turn dinner into an unpleasant "lecture time". That will turn kids off not only manners, but dinner, and you, too. *Check your own example. Don't show up for dinner in just your underwear unless you want your kids to do the same. *Don't always consider your kids lazy and dirty ones. Instead, point out the behavior in a tender way. For example: " It' s a good idea to unfold your napkin, so if food falls you won't dirty your clothes." *Teach your kids good manners in the form of a game. One night a week, try to have a formal dinner. Try dressing up, serve a special meal, and expect more formal manners. That will help improve their sense of manners. *Make kids understand part of the tradition. Invite guests over and let kids help serve them. This helps them indirectly learn about table manners. *Try dining out once in a while. Fast food restaurants aren't counted. Try a nice restaurant and let kids order their own food, pay the bill and give the tip.

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.

answer:
A

Article: Passwords are no safeguards Typing your password or credit card number into a computer is a moment's work. But if you think your personal details disappear as soon as you hit the Return key, think again: they can sit on the computer's hard disk for years waiting for a hacker to take them. As people spend more time on the web and hackers become more experienced, the dangers of storing personal information on computers are growing by the day, security experts say. There are some safe-guards, such as never allowing your computer to store your passwords. But even that in no guarantee of security. When you type in a password, it is stored in random access memory (RAM), where it is held temporarily until other data overwrites it or the computer is switched off. But every so often , the computer copies the contents of its RAM onto hard disk, where it is easy to prey for a hacker, who can read it directly or design a worm to e-mail it back. The longer sensitive data stays in RAM, the more likely it is to be copied onto the disk, where it stays until it is overwritten-which might not happen for years. Tal Garfinkel and colleagues from Stanford University have created a software tool which simulates the workings of a complete computer system. Within the simulation, sensitive data can be tagged and then tracked as it passes through the system. Next, Garfinkel and his team simulated computers running common software that regularly handles passwords or secret personal information, such as Internet Explorer, the Windows login script and Apache server software. In a paper to be presented, they conclude that the programs took no measures to limit the length of time the information is kept. Some of the tested software even copied the sensitive information, obviously without restraint .
Question: What does the passage mainly talk about?
Options: (A) It's important to set passwords to your computer. (B) Passwords help keep your personal information. (C) It's unsafe to store personal information on computers. (D) There are some safeguards for your personal information.
answer:
C
