Question: I'm taking a test and have to guess the right answer to the question after the article. Article: Have you ever heard that we humans use only ten percent of our brains? This opinion holds a certain appeal because if it were true, then we could instantly become ten times more intelligent just by firing up that sleepy majority of the brain! The idea that we use only a small part of the brain dates back to animal experiments in the 19th century. When scientists stimulated a specific part of the brain, the animal moved its leg or tail. If a tiny part of the brain could do something so great, what was the use of the rest of the brain? Some scientists assumed that large parts of the brain were simply useless. Then, in the early 20th century, scientists observed that stimulating certain parts of the brain had no physical effects. They named these seemingly useless parts of the brain the "silent cortex." Today we know that in humans, much of the "silent cortex" is actually devoted to complex activities like language, learning, and imagining. Brain scans have shown that different parts of the brain become much more active as we shift our attention and focus, but even as we sleep, many areas of the brain are extremely active. Would you be smarter if your entire brain constantly worked to maximum capacity ? Interestingly enough, the opposite is probably true. The less brain activity you need to perform a given task, the more the brain as a whole is able to do. Question: "Silent cortex" has proved to be _ . Options: A: sensitive to stimulation B: useful in complex activities C: responsible for physical reaction D: more active than the other parts of the brain
Answer: B

Question: I'm taking a test and have to guess the right answer to the question after the article. Article: What do you do when you need to look something up? Go to the library? Open an encyclopedia ? Click onto the Internet? These days, most people go straight to Wikipedia, the online encyclopedia. But how reliable is it? There is no denying the popularity and usefulness of Wikipedia. It attracts as many as 78 million visitors every month, and the site is available in more than 270 different languages. It's one of the most comprehensive resources available, which includes almost all details, facts and information that maybe concerned. It's got much more information than an ordinary encyclopedia. The site is updated on a daily basis by thousands of people around the world. Anyone with an Internet connection can log on and edit the contents or add a new page. And you don't need any formal training. Of course, there are some controls. Wikipedia has a team of more than 1,500 administrators who check for false information. And main targets for harmful comments(such as politicians) are _ to public editing. But with more than 16 million articles to keep an eye on, it isn't easy. So, while Wikipedia benefits from being constantly updated with information from all over the world, it's also open to "vandals" . Some of the damage is easy to notice. One person drew devil horns and a moustache on Microsoft chairman Bill Gates' photo, while another edited Greek philosopher Plato's biography to say he was a "Hawaiian weather man who is wildly believed to have been a student of'Barney the purple Dinosaur' and to have been deeply influenced by his dog, Cutie". But other things are harder to spot. The most common form of vandalism involves adding tiny items of false information into the biography of a famous person. Unbelievably, some of this misinformation has appeared in newspapers, with The Daily Mail, The Guardian and The Independent all having fallen victim to the dirty tricks. For example, in an article about British comedian Sir Norman Wisdom, one newspaper claimed that he co-wrote Dame Vera Lynn's wartime hit There'll be... Question: We can learn from the passage that _ . Options: A: because of its popularity, 78 million people from 270 countries visit Wikipedia monthly B: Wikipedia is the most comprehensive resource with all information we need C: anyone who has access to the Internet can edit any contents of Wikipedia as they like D: the primary job of the administrator is to make sure true information is conveyed
Answer: D

Question: I'm taking a test and have to guess the right answer to the question after the article. Article: In 1991, Kentucky Fried Chicken announced that it was officially changing its name to "KFC" as well as updating its packaging and logo with a more modern look. The public relations reason was that health-conscious consumers associated the word "fried" with "unhealthy", causing some of them to completely avoid the wide variety of "healthy" menu items. The new title and image were designed to attract customers to a restaurant now offering foods branded as "better for you". It sounded good, but the real reason behind the shift to KFC had nothing to do with critical consumers. In 1990, the Commonwealth of Kentucky, trapped in debt, took the unusual step of trade marking its name. Therefore, anyone using the word "Kentucky" for business reasons would have to obtain permission and pay licensing fees to the Commonwealth of Kentucky. It was an unusual and brilliant scheme to lighten government debt, but it was also one that alienated one of the most famous companies ever associated with Kentucky. The Kentucky Fried Chicken chain refused as a matter of principle to pay royalties on a name they had been using for four decades. After a year of fruitless talks, Kentucky Fried Chicken changed their name instead, introducing new packaging and products to hide the real reasons behind the change of the name. Kentucky fried Chicken was not the only one who bravely refused to give in. The name of the most famous horse race in North America, held every year at Churchill Downs, was changed to "The Run for the Roses" for similar reasons. In November 2006, KFC and the State of Kentucky finally reached a settlement over the use of the trademarked word "Kentucky", and the restaurant chain announced it would be reusing its former name of "Kentucky Fried Chicken". Question: It can be inferred from the passage that _ . Options: A: KFC is still not allowed to use the name of "Kentucky Fried Chicken" B: "Kentucky Fried Chicken" changed its name after several years of talks C: the name "Kentucky Fried Chicken" had only been used for a short time D: the original name of the horse race "The Run for the Roses" contained the word "Kentucky"
Answer:
D
