Article: If you see someone drowning, speed is very important. Once you get him out of the water, if he isn't breathing, you have four minutes before his brain is completely destroyed. Support his neck, move his head back and press his chin upwards. This stops the tongue blocking the airway in the throat and is sometimes enough to get him breathing again. If that doesn't work, start mouth-to-mouth breathing. Press his nostrils (the two holes at the end of your nose, through which you breathe and smell things) together with your fingers. Open your mouth and take a deep breath. Blow into his lungs until his chest rises, then remove your mouth and watch his chest fall. Repeat twelve times a minute. Keep doing until professional help arrives. To bring a child back to life, keep your lips around his mouth and gently blow into his mouth. Give the first four breaths as quickly as possible to fill the blood with oxygen. If, in spite of your efforts, he starts turning a blue-grey colour, and you can feel no pulse , then pressing is the last chance of saving his life. With arms straight, rock forwards, pressing down on the lower half of the breastbone. Don't be too hard or you may break a rib. Check how effective you are by seeing if his colour improves or his pulse becomes independent to your chest pressing. If this happens, stop the pressing. Otherwise continue until rescue arrives. Question: Which of the following statement is true? Yes or no, is the answer "If a man does not breathe for four minutes, his brain will be completely destroyed."?
No

Article: In order to save money for a trip to Thailand to visit her family and friends, Emma White, a keeper in California, worked overtime. She saved more than 900 dollars and was planning to buy a ticket, but she lost her purse with all her money and credit cards . Emma looked through the garbage and all the buildings where she worked but came up empty-handed. She went home heartbroken. She believed that she had lost her money forever. While Emma was at home, sad and depressed, a homeless man was searching through the garbage looking for things to sell. As he was looking through a garbage bag, he found something wrapped in a plastic bag. The homeless man, who did not want to be recognized, took the purse to Sherry Wesley, because Sherry Wesley knew him from her volunteer work at a homeless shelter. The homeless man came to Sherry Wesley with the wad of money and said, "This probably belongs to someone that you work with; can you find the owner?" Sherry Wesley works in one of the buildings that Emma cleans and she knew Emma had lost her purse. Emma was amazed when she heard the good news. "I couldn't believe it when they called me," she said. "He has a very big heart. If someone else had found the purse, the money would be gone." As a reward, Emma gave the man 100 dollars. The homeless man gave half of the money to Sherry Wesley and asked her to donate it to charity for him. Question: Why did Emma work overtime? Yes or no, is the answer "To save money to visit her family and friend."?

Q: Article: A Dutch artist and designer has come up with a device which he hopes will get rid of pollutants from Beijing's smog skies, creating clean air for the city's mask-wearing people. An electromagnetic field will pull particles in the smog to the ground where they can be easily cleaned. "It's like when you have a balloon which has static and your hair goes toward it. Same with the smog," says artist Daan Roosegaarde. His studio has reached an agreement with the Beijing government to test the technology in one of tile capital's parks. With its skies regularly covered by dirty gray smog, Beijing this week announced a series of emergency measures to handle the problem. Roosegaarde says an indoor model device has already proven it works and is confident that the results -- with the help of a team of scientists and engineers -- can be replicated outside. "Beijing is quite a good place because the smog in Beijing is quite low. It lies in a valley so there's not so much wind. It's a good environment to explore this kind of thing." "We'll be able to purify the air and the challenge is to get the top of the smog so you can see the sun again." Roosegaarde acknowledges that projects like this are a way of drawing attention to the problem, rather than a practical solution to Beijing's awful air pollution. "This is not the real answer for smog. The real answer has to do with clean cars, different industry and different lifestyles." However, he hopes the project will make a "fundamental statement" by allowing the city's people to realize the difference between breathing clean and smog-filled air. Question: The device works by _ . Yes or no, is the answer "pulling pollutants to the ground with an electromagnetic field"?
A: No

Article: "Dear anybody. Your email address has been chosen by our computer. So, for no reason, we'd like to give you a million dollars. All you need to do is give us your bank account numbers. Can we interest you in some diet pills? And, by the way, I want to marry you." I hate to let you down, but there is no "million dollars". The diet pills don't exist - and your future "husband" or "wife" has just proposed to a million others. These and a hundred other stories have been made up to steal your personal information or money or maybe just to infect your computer with a virus. Welcome to the world of junk email. Junk email - or spam - is probably the biggest global business that's ever existed. Billions of spam emails are sent every day, making up around 80% of all email traffic. These incredible volumes of spam slow down the whole internet and cost businesses millions of dollars just trying to keep up with the next trick. Your email programme probably includes a spam filter, which sorts out the mail you do want from the junk. But it's impossible to stop it all and if you put together the seconds it takes to see through the deception in each one, they add up to a significant amount of lost time dealing with the spam that does get through. But who could fall for such obvious tricks? Probably very few of us - one in a million, perhaps. But when you are sending billions of these every day, for next to no cost, it doesn't take a genius to work out that someone is getting very rich. But who? It's incredibly difficult to find out. Most spam is sent using anonymous networks of infected computers, called "botnets", some of which are made up of tens of millions of computers across dozens of countries. Maybe your own laptop is sending out marriage proposals right now. It's enough to put you off using email again! So what can you do to defend yourself? You could set up a separate email account for online use, or maybe leave out the @ symbol when you write your email address online. An up-to-date web browser and antivirus...
