Read the following article and select the best answer. Article: Many psychologists in the early twentieth century believed that humans use only 10 percent of their brains, and even the great Albert Einstein once wrote that most people use only a small portion of the grey matter between their ears. It's a theory that has often been put forward in television documentaries; magazines, advertisements and books over the past century. But nearly all scientists now agree the 10 percent theory is completely . In fact, they question how this figure was ever arrived at in the first place and what areas of the brain are supposed to be unneeded. The theory supposes that if 90 percent of the brain were removed, a person would Still be able to function normally, while in reality it is known that damage to even a small area of the brain can result in extremely serious physical injury different activities and that many areas of the brain are used at the same time for some complex activities or thought processes. Throughout the course of one day, most .areas of the brain are active at some time, even during sleep. The 10 percent theory suggests that certain areas o' the brain are not used, but scans slow activities throughout the entire brain and not in any separate part. The final argument against the 10 percent theory is the fact that doctors carefully map the brain before removing brain cancers so that they don't affect other essential areas. From an evolutionary point of view, it's highly unlikely butt our comparatively larger brains would have evolved from our ancestors if the extra areas were not needed. In fact, there is absolutely no evidence support the 10 percent theory. Question: How did the 10 percent theory get such widespread popularity? - It was promoted in various types of copular media. - Albert Einstein argued strongly in support. - It was proven in scientific research. - Few people could prove it wrong.
It was promoted in various types of copular media.

It is the stuff of nightmares for those whose busy work schedule or busy family life means getting up early and staying up late. Scientists claim that the modern tendency to delay going to bed in order to get through more of the items on the 'to do' list has serious health consequences. But take care. Those who have too much sleep are also more likely to suffer a heart attack. While the extra sleeping is unlikely to be the cause, long-term illnesses such as heart disease often make sufferers feel tired, so sleeping for longer than nine hours a night may be an early warning sign. Researchers found that those who slept for less than six hours were almost 50 per cent more likely to suffer a heart attack and 15 per cent more at risk of strokes. They believe that not having enough sleep disrupts the balance of two key hormones , ghrelin and leptin , which control the appetite. Poor sleepers tend to eat more and are more likely to be fatter, so are at greater risk of high blood pressure and heart disease, which lead to heart attacks and strokes. Experts recommend adults get at least six or seven hours' shut-eye a night to stay healthy. But as many as 60 per cent of us do not think we are sleeping enough, with a third suffering from sleeplessness. The researchers, from the University of Warwick, warned that trying to push too much into one day by going to bed late and getting up early could lead to serious illnesses later in life. They looked at the sleeping habits of almost 475,000 participants from 15 previous studies across eight countries, including the UK, the U.S., Japan, Sweden and Germany. Their findings, published in the European Heart Journal, show that those who slept for less than six hours were 48 per cent more likely to develop or die from heart disease and 15 per cent more likely to develop or die from a stroke. Not having enough sleep decreases the levels of leptin in...

Q: Read the following article and select the best answer. Article: Perhaps you have been told about some habits which stop a person reading fast, and have been strongly asked to break those habits which you might have. Do you still have any of these bad habits7 Check yourself by answering "yes" or "no" to these questions: 1. Do you move your lips when reading silently? 2. Do you point to words with your finger as you read? 3. Do you move your head from side to side as you read? 4. Do you read one word at a time? If you answer "yes" to any of these questions, start at once to break the habit. If you move your lips, hold your fingers over them, or hold a piece of paper between your lips while you are reading. Then if your lips move, you will know it and can stop them. If you point to words, hold the two sides of your book, one side with your left hand, the other side with your right hand. Then you will not have a free finger to use in pointing while reading. If you move your head, place your chin in one hand, and hold your head still(,). If you read no more than one or two or three words at a time, you need to work very hard in learning to take in more words at each glance as your eyes travel across the lines of words. Question: When your eyes travel across the lines of words, _ - you need to read the words out - you need to look at every word carefully - you need to read several words at a time - you need to remember every word
A: you need to read several words at a time

Q: Read the following article and select the best answer. Article: For many of us, a little time with our smartphones or iPads before sleep is the highlight of the night. But would you still think it is relaxing if you knew that it damages or destroys your sleep? Scientists say that's exactly what it does. In ancient times, when there were no lamps, telephones or smartphones, the sun was the main source of light. When the sun went down, our brains took that as a signal to start producing melatonin , a chemical that helps us sleep. However, a healthy amount of melatonin can only be produced in complete darkness.Any light in your bedroom--even the one on the alarm clock or the charging indicator on your cellphone--could disturb the process, not to mention something as bright as smartphone and iPad screens. We tend to hold these much closer than a television or laptop, which allows them to shoot far more light straight into our eyes. "This is particularly worrisome in populations such as young adults and adolescents, who already tend to be _ ," said researcher Brittany Wood at Rensselaer Polytechnic Institute."Lack of sleep among teens is leading to depression, selfharm, low concentration and poor performance at school," she added. While all lights are the enemy of sleep, not all colors of light have the same effect. Our eyes are particularly sensitive to blue light, which is common during the day. Most of the light coming from electronic screens is blue light and it fools our brain into thinking it's still daytime. By contrast, orange or red light has less influence on melatonin production, because our brains recognize it as a signal that the day is ending, according to The Telegraph. Asking yourself to keep your hands off your smartphone before bedtime might seem unreasonable, but you should at least remember to dim the screen or hold it farther away from your eyes. You could also wear a pair of orange sunglasses that take away the harmful blue light. Question: In the writer's opinion, which is a correct suggestion? - You should go to bed when the sun goes down. - You should use an orange or red light electronic screen. - You should wear a pair of blue sunglasses when sleeping. - You should avoid blue light as possible as you can before bedtime.
A: You should avoid blue light as possible as you can before bedtime.
