Article: Someday a stranger will read your email without your permission or scan the website you have visited. Or perhaps someone will casually glance through your credit card purchases or cell bills to find out your shopping preferences or calling habits. In fact, it is likely that some of these things have already happened to you. Who would watch you without permission? It might be a girlfriend, a marketing company, a boss or a criminal. Whoever it is, they will see you in a way you never intended to be seen----- _ stcentury is the equal of being caught naked. Psychologists tell us boundaries are healthy and that it is important to reveal yourself to friends, families and lovers at appropriate time and places. But now few boundaries remain. The information you leave everywhere makes it easy for strangers to reconstruct who you are, where you are and what you like. Believe it or not, we live in a world where you simply can't keep a secret. The key question is: does that matter? When you ask Americans about privacy, most say they are concerned about losing it. But people say one thing and do another. Only a tiny part of Americans change any behaviors in an effort to preserve their privacy. Few people turn down a discount at tollbooths to avoid using the EZ-Pass system that can track automobile movements. And few refuse to offer personal information like Social Security numbers to get supermarket loyalty cards. But privacy does matter--at least sometimes. It is like health: when you have it, you don't notice it. Only when it is gone do you wish you had done more to protect it. Question: Which of the following may serve as the best title of the passage? Yes or no, is the answer "Privacy Is Getting Lost."?
No

Article: A team of US psychologists have found that talking to another person for ten minutes a day helps with memory. "Socializing is just as effective as more traditional kinds of mental exercise in memory and intellectual performance," Oscar Ybarra, a psychologist at the University of Michigan Institute for Social Research, said in a statement. In one investigation, they analyzed data on 3610 people, aged 24 to 96. They found that the higher their level of social interaction , the better their cognitive functioning. Social interaction includes getting together or having phone chats with relatives, freinds and neighbors. In another experiment, the researchers conducted lab tests on 76 college students, aged 18 to 21, to evaluate how social interactions and intellectual exercises affected the results of memory and mental performance tests. The students were divided into three groups: the social interaction group had a discussion of a social issue for 10 minutes before taking the tests; the intellectual activities group completed three tasks (including a reading comprehension exercise and a crossword puzzle) before the tests; and a control group watched a 10-minute clip of the Seinfeld television show. "We found that short-term social interaction lasting for just 10 minutes improved participants' intellectual performance as much as engaging in so-called 'intellectual' activities for the same amount of time," Ybarra said. The study was expected to be published in the February issue of the journal Personality and Social Psychology Bulletin. Question: What's the main idea of the passage? Yes or no, is the answer "Social interaction makes you smart"?
No
