Problem: Write a multi-choice question for the following article, with the given choices and answer: Article: Password strength has been a topic about the Internet lately. I have seen lots of clever methods for generating and remembering strong passwords. Some are better than others, but in my opinion , none are adequate . Here's the problem : it doesn't matter how strong your passwords are if you use the same one on multiple sites. All it takes is for a site to get hacked , like Gawker media, or even Sony did , and now your super-strong password has been stolen , and every site on which you used that password has been accessed . So, the bottom line is that no matter how strong your passwords are , and no matter what clever tricks you use to help you remember them , if you surf the Internet often , the only truly secure password system is what you need . Enter LastPass. It's not the only password manager out there, but I like it the best. You create ONE strong password that you have to memorize and use it to access your LastPass database . The LastPass database is stored online, on LastPass's servers. LastPass recognizes the site you're on and automatically logs you in (after , optionally , asking you to re-enter your master password). LastPass also has automatic form fill and automatic password generation. This means that you can have a different , unique , very strong password for every site you log into , but you only have to remember one master password . It's the best of both worlds. One argument against LastPass is that if their database is attacked , then all of your sites are in danger, and that's true, but given that their entire line of work is keeping that information safe , I'm willing to take that chance. The alternative is rolling dice or picking phrase to create passwords, writing all of them down on a piece of paper or something , and then having to manually type them in when I go to a site . A terrible mess. There is a free version of LastPass , with additional features unlocked if you pay $ 12 for a year's subscription . ----Joshua Bardwell Options: A share his experience B introduce a product of good quality C advertise his product D teach how to use a new product Answer: B introduce a product of good quality Question:

A: Joshua Bardwell writes the passage to _ .

Problem: Write a multi-choice question for the following article, with the given choices and answer: Article: A new reading tool was put on the market this week for the two-to five-year-old set. It is sold for at least $389, an expensive purchase for a kid - and that doesn't even include a $99 annual subscription fee for games, e-books, and age-appropriate software. That might be fine for parents willing and able to pay thousands for private nursery schools, but will the tool actually help kids learn language and reading skills more effectively than traditional books? Probably not, said Dr. Michael Rich, director of the Center for Media and Child Health at Children's Hospital Boston. "There is a sensory components to books that isn't there with e-books," he explained. "You can smell it, turn the pages, and taste it, as young kids are likely to do." That might help little ones become more familiar with the books, helping them learn from them, but far more important is whether a person is actually sitting with them while they're looking at the pages. Researchers have shown time and again that kids learn better when they're having interaction with real people, rather than electronic voices reading to them from a computer or speaking to them from the TV. A Georgetown University study found that kids who learned to put on gloves from watching a video took six times as long to learn the process as those who watched it shown by an adult standing in front of them. "I'm a big believer in teaching kids to live in the digital society and use what the rest of the family uses, but they do need to be _ ," said Dr. Gwenn O'Keeffe, a Boston-based children's doctor and spokesperson for the American Academy of Pediatrics. "We don't recommend that young kids use any type of technology for very long since they have the attention span of a butterfly." Options: A is mainly used to entertain kids B can be accepted by most families C is designed for preschool kids D can download games for free Answer: C is designed for preschool kids Question:

A: According to the text, the new tool _ .

Problem: Write a multi-choice question for the following article, with the given choices and answer: Article: Exercise is one of the few factors with a positive role in long-term control of body weight. Unfortunately, that message has not gotten through to the average American, who would rather try switching to "light" beer and low-calorie bread than increase physical efforts. The Centers for Disease Control, for example, found that fewer than one-fourth of overweight adults who were trying to lose weight said they were combining exercise with their diet. In rejecting exercise, some people may be discouraged too much by caloric-expenditure charts; for example, one would have to quickly walk hard three miles just to work off the 275 calories in one delicious Danish pastry . Even exercise professionals accept half a point here. "Exercise by itself is a very tough way to lose weight," says York Onnen, program director of the President's Council on Physical Fitness and Sports. Still, exercise's supporting role in weight reduction is vital. A study at the Boston University Medical Center of overweight police officers and other public employees confirmed that those who dieted without exercise regained almost all their old weight, while those who worked exercise into their daily routine maintained their new weight. If you have been sedentary and decide to start walking one mile a day, the added exercise could burn an extra 100 calories daily. In a year's time, assuming no increase in food intake, you could lose ten pounds. By increasing the distance of your walks gradually and making other dietary adjustments, you may lose even more weight. Options: A To stress the importance of maintaining proper weight. B To support the statement made by York Onnen. C To show the most effective way to lose weight. D To introduce the study of the Boston University Medical Center. Answer: C To show the most effective way to lose weight. Question:
