Article: Studies have documented that smiling is a universal and effective way to lift mood. But in the latest research on the power of the smile, researchers led by Marcus Munafo of the University of Bristol in England found that even seeing smiles on the faces of others can have a profound effect on a person's tendency toward violence or aggression -- that is, as long as that person recognizes the smile as one of happiness, and not as a sneer . Munafo and his colleagues conducted a series of experiments involving normal adults and highly aggressive teens referred to a youth program, either by educational authorities or the courts. About 70% of the teens already had a criminal record. In the first experiment, 40 healthy adults, aged 1830, looked at facial expressions on the computer ranging from happy to angry with increasingly difficult ones to _ in between. Participants were asked how angry they felt and then had to rate the images as displaying either happiness or anger -- there was no option for "unclear" or "unable to tell". From these ratings, the scientists could generate a score of their preference toward happiness or anger. Previous research found that aggressive people -- including violent offenders -- tend to consider even a common expression as an unfriendly one. "You looking at me?" can easily turn a simple question into a tragic fight. Based on their original scores, half of the participants were then told by the computer that some of the unclear faces that they had rated as angry should have been scored as happy. This was intended to guide them toward judging the inbetween faces more positively. The other 20 received feedback that simply proved their first choices, creating a control group. After this training, both groups were tested again and the group that received the biased feedback shifted its ratings of unclear faces toward the happy side. Participants were also asked to rate their level of angry feelings again after completing the second round of testing. Those who were trained to consider... Question: According to Munafo's research, the anger and violent behavior in some youths resulted from _ . Yes or no, is the answer "their misunderstanding of facial emotions of others"?
No

Article: The Internet has got into all the fields of our life. We can study and work on it. We can find a job on it. We can communicate on it. We can treat friends on it. We can buy and sell on it. We can do almost everything on the Internet, and almost anywhere at any time. However, although the Internet provides services for us, it is silently getting our privacy to some degree. The services on most websites require our personal information. If we want to enjoy these services, we have to provide much of our information, including our names, sex, addresses, telephone numbers and sometimes bank accounts. Because weak network sometimes is unsafe, our information might be open, stolen or sold. Even sometimes _ will be used freely by others. Considering the above mentioned, you must pay attention to the safety of your information when using the Internet. First, when you need Internet service, you should always look through those big legal websites. Second, if the service requires important personal information, you should think twice before you type it in. Third, store your own important card key and don't tell others easily. Question: According to the passage, we shouldn't _ when using the Internet. Yes or no, is the answer "give our friends' information to others"?

Article: Scottish pupils recently were part of a new scheme that allowed them to take their exams online. Those examinations provided a glimpse of the future in May when 120 _ in 10 centers in Scotland sat in front of computers to take a multiple-choice online exam. Although candidates were using a computer mouse instead of a pen, in all other ways the exam was the same as normal. Exam rooms were set out to ensure that only the candidates and the teachers were able to see the individual screens. The online answers were sent directly to a safe area. According to the students at St Ninian's in East Renfrewshire who took an online French exam, it was definitely the most motivated they had ever felt when taking an exam. "I could go as fast as I wanted to, rather than as slow as everyone else wanted to," said one. "It was better than looking back and forth between the questions," said another. One pupil even described it as fun. Their head teacher, Dorothy Graham, was not so surprised, "They are so used to doing things on computers that it seems natural for them. The boys liked it because they didn't have to worry about how neat their work was." The only things that worried her were power cuts and systems' crashing. It's thought that online exams could be the norm in about five years. However, last year there were warnings about computerizing exams in England and Wales. It's thought that it could be unfair to some students if they come from homes without access to a computer. Question: We can learn from the passage that it is mainly about _ . Yes or no, is the answer "taking exams online"?
No

Article: The man who invented Coca-Cola was not a native Atlanta, but on the day of his funeral every drugstore in town shut up the shop in honor of him. He was John Styth Pemberton, born in 1833 in Knoxville, Georgia, eighty miles away. Pemberton was a chemist, sometimes known as Doctor, who, during the Civil War, became an officer and led a cavalry troop. He settled in Atlanta in 1869, and soon began making such patent medicines as Triplex Liver Pills and Globe of Flower Cough Syrup. In 1885, he registered a trademark for something called French Wine Coca-Ideal Nerve and Tonic Stimulant. A few months later, he formed the Pemberton Chemical Company, and hired an accountant named Frank M. Robinson, who had not only a good head for figures, but, attached to it, so unique a nose that he could judge the ingredients of a batch of syrup merely by sniffing it. In 1886 --- a year in which, as contemporary Coca-Cola officials like to point out, the English writer Conan Doyle made Sherlock Holmes known publicly and France found the truth about the Statue of Liberty --- Pemberton invented a syrup that he called Coca-Cola. It was a change of his French Wine Coca. He had taken out the wine and added a bit of caffeine, and, when the end product tasted awful, had thrown in some cola nut oil and a few other oils, mixing the mixture in a three-legged iron pot in his back yard and swishing it around with an oar. He distributed it to soda fountains in used beer bottles, and Robinson, with his elegant account's script, instantly designed a label, on which "Coca-Cola" was written in the style which is still employed. Pemberton looked upon his mixture less as a drink than as a headache cure. One morning in 1886, a man suffering from a headache dragged himself into an Atlanta drugstore and asked for a bottle of Coca-Cola. According to usual practice, druggists should pour a teaspoonful of syrup into a glass of water, but at that time, the man on duty was too lazy to walk to the fresh-water tap. Instead, he mixed the syrup with some soda... Question: Why do contemporary Coca-Cola officials especially like to mention the year 1886? Yes or no, is the answer "Because they are still proud of Pemberton's invention."?
