Q: Article: Broken rubber bands and flat tires requiring replacement could soon be a thing of the past. French researchers have developed a new kind of rubber that can repair itself when broken.The new rubber is made from widely available materials including vegetable oil and a common industrial chemical.All the materials are considered safe to the environment and can be easily reused. The best part is that the new rubber can be repaired and used again and again without losing its strength or ability or stretch.When cut, the rubber can be made new again, simply by pressing the two broken ends back together. The product can be repaired at room temperature, around twenty degrees Centigrade;other self-healing materials require higher temperatures for repair. Traditionally, rubber substances are made from huge molecules connected by strong chemical links, or bonds.The new rubber is made of smaller molecules.The molecules are linked together using hydrogen bonds.When connected in this way, the molecules act like one long molecule, forming what is called supramolecular networks .When the rubber is cut, the molecules attempt to connect with whatever molecule is near them.When pressed together, the molecules are able to repair themselves at the molecular level, making the repaired rubber like new. However, time is an important element in the process.If the broken ends are not brought together quickly, a repair is not possible.This is because molecules will form bonds with molecules on their own side.The inventors say the surfaces of the rubber can be repaired within a week of being separated. The rubber is the creation of scientists at the Industrial Physics and Chemistry Higher Education Institution in Paris.The organization is part of France's National Center for Scientific Research.The new material is described in greater detail in the research publication Nature. Question: If we want to know more about the technology of this kind of new rubber, where can we get the information? Yes or no, is the answer "In a research magazine."?
A: No

Q: Article: Everyone's at it, even my neighbors. I thought I might be the only person left in the world who hadn't done an eBay deal. So I decided to try my hand at online auction. Buying for beginners: Sign up on www.eBay.co.uk. Most items (e.g. tables, computers, and books) ready for auction will come with a picture and a short description; others may be marked with "Buy It Now" and have a fixed price. You can buy these right away. If the item is being auctioned, you offer the highest price you are prepared to pay and eBay bids for you.The bid will be increased little by little until it goes beyond your highest bid, then you are emailed and asked if you would like to bid again. Auctions last up to 10 days, and when they finish you get an email telling you whether you have won the item. How to pay: Sellers decide how they would like to be paid and you need to check this before placing a bid as you might not want to post a cheque or postal orders. The easiest way is through PayPal, an online payment system that takes the money away from your credit card. Selling made simple: If you plan to sell on eBay, it helps to include a picture of the item.I followed my friends' advice and put up the items I wanted to sell for a 10-day auction, starting on a Thursday.This way buyers had two weekends to bid. The big things in life: It's easy to post a small item, but furniture is a big part of eBay and this has to be collected or sent by delivery men.Check the ways of delivery before you bid. Question: The passage suggests that a buyer _ . Yes or no, is the answer "has more than one chance to bid"?
A: No

Q: Article: It's really a tough job for automakers doing marketing and sales in China, where competition is acute and customers have little loyalty. They have tried a range of tricks in recent years. But there should be a moral bottom line. Unfortunately, a Buick dealership used the tragedy of a two-month-old infant to advertise its cars last week on Weibo - Micro blog. And Hyundai Motor followed suit. On March 4, an SUV was stolen with the infant left inside alone in the northeastern city of Changchun. The news spread widely on Weibo after the baby's father called the local police and radio station for help. The next day it was revealed that the infant was choked to death and buried in snow by the thief. The online community expressed its deeply felt sympathy and condolences. The Buick dealership posted a photo of the baby and two of its cars on its official Weibo account to advertise its GPS system that can locate the stolen car. "A few thoughts on the Changchun stolen car and baby incident: when buying a car it's entirely OK to choose a brand with advanced technology," said the post. Though the post was made before tragic fate of the infant was known, the action generated a storm of outrage on Weibo. Some online commentators said it is "marketing at the cost of lives" and "extremely _ ." Worse was the post on Hyundai's official Weibo account that advertised the anti - theft system on its new SUV Santa Fe, an entry made after the child was known to have died. The action also enraged micro bloggers. Both posts were soon deleted. The Buick dealership made an apology on Weibo to the family of the victim and the public. But screenshots saved by users continued to be posted and the negative impact on both brands persists. The two brands probably didn't expect such a firestorm of fury from the Internet community, but they really made a big mistake sinking below the moral bottom line. They certainly ruined their own brand images. The Chinese have the same proverb as the English language - a little leak will sink a great ship.... Question: The reason why Hyundai's post was worse than Buick's is that _ . Yes or no, is the answer "Hyundai's post was made after people knew the infant had died"?
A: No

Q: Article: Anger is good for you, as lon g as you control it, according to new psychology research. A new study from Carnegie Mellon University shows anger may help people reduce the negative impacts of stress and help you become healthier. "Here getting emotional is not bad for you if you look at the case of anger," said Jennifer Lerner of Carnegie Mellon. "The more people display anger, the lower their stress responses." Lerner studied 92 UCLA students by asking them to count back from 6,200. They must say out loud every thirteenth number. Researchers disturbed them by asking them to count faster or ask them other questions. If they made any mistakes, they had to restart from the very beginning. Many students felt depressed about making so many mistakes or got angry because the researchers were interrupting them. Lerner used a hidden video camera and recorded all their facial expressions during the test. The researchers describe their reactions as fear, anger and disgust. Other researchers recorded the students' blood pressure, pulse and production of a high-stress hormone called cortisol. People whose faces showed more fear during th e experiment had higher blood pressure and higher levels of the hormone. Both can have lasting effects such as diabetes , heart disease, depression and extra weight gain. When people feel fear, negative impacts increase, but when they get angry, those negatives go down, according to the study. "Having that sense of anger leads people to actually feel some power in what otherwise is maddening situation," Lerner said. Lerner previously studied Americans' emotional response to the 911 terrorist attacks two months after the incident. She found people who reacted with anger were more optimistic. These people are healthier compared with those who were frightened during the event. So in maddening situations, anger is not a bad thing to have. It's a healthier response than fear. Question: What is the story mainly about? Yes or no, is the answer "The findings of new psychology research."?
A: Yes
