Question: Read the following article and answer the question. 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: If you need less brain activity to perform a task, _ . Answer:
OPTIONS:
- you will feel sleepy
- you must shift your focus
- you can use your brain to the fullest
- you will be more productive
Answer: you will be more productive

Question: Read the following article and answer the question. 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...
