Ques:I'm taking a test and have to guess the right answer to the question after the article. Article: Going to sleep may seem pretty boring compared with all the fun things you do while you are awake. But there's a lot going on in your mind and body while you are sleeping. Sleep, in fact, is as important to your survival as eating and drinking. Sleep improves your mood, makes you a better athlete, and helps you remember and understand what you learned during the day. During sleep your temperature drops. Your heart rate slows. Down goes the pressure of the blood moving through your veins. A chemical that controls growth (called a hormone) moves into your bloodstream. Scientists think that sleep brings back energy and improves your immune  system. We know what happens while we're asleep because scientists study volunteers who sleep in laboratories. The sleepers are connected with machines that measure brain waves, eye movements and muscle activities. Sleep is like a school day: it's divided into different periods, or stages. When you are awake, your brain waves fire rapidly. As you begin to relax and drift into the first stage of sleep, your brain produces slower-moving waves and you lose awareness of your surroundings. As you slide to deeper sleep, your body repairs itself from the normal wear and tear of daily life. Then, as you begin to drift back up to a lighter sleep, your mind becomes more alert, and your dreams begin. You are in REM sleep. REM is the name for the rapid eye movement that happens while you are dreaming. During REM sleep, your eyes move back and forth behind your lids , as though you were watching a movie. During other stages, you might move in bed, but during REM sleep you're still. That's probably because if you could move, your body would act out your dreams. As you get close to morning, you spend more time in REM than in deep sleep, so you dream more. Researchers know that during REM sleep the part of the brain that handles learning and thinking is very active. Getting too little sleep can affect your personality. Experts recommend that children get at least nine hours sleep a night. Question: Suppose this is the course of your sleep, in which part of the course do you have more dreams? Options: A: Light sleep. B: Deep sleep. C: REM sleep. D: The first two stages of sleep.

Ques:I'm taking a test and have to guess the right answer to the question after the article. Article: In recent years, a growing body of research has shown that our appetite and food intake are influenced by a large number of factors besides our biological need for energy, including our eating environment and our perception of the food in front of us.      Studies have shown. for instance. that eating in front of the TV (or a similar distraction) can increase both hunger and the amount of food consumed. Even simple visual cues( ). like plate size and lighting, have been shown to affect portion size and consumption.       A new study suggested that our shot-term memory also may play a role in appetite.  Several hours after a meal, people's hunger levels were predicted not by how much they'd eaten but rather by how much food they'd seen in front of them --- in other words, how much they remembered eating.       This difference suggests the memory of our previous meal may have a bigger influence on our appetite than the actual size of the meal. says Jeffrey M . Brunstrom , a professor of experimental psychology at the University of Bristol.     "Hunger isn't. controlled solely by the physical characteristics of a recent meal. We have identified an independent role for memory for that meal." Brunstrom says. "This shows that the relationship between hunger and food intake is more complex than we thought."      These findings echo earlier research that suggests our perception of food can sometimes trick our body's response to the food itself. In a 2011 study, for instance, people who drank the same 380-calorie milkshake on two separate occasions produced different levels of hunger-related hormones, depending on whether the shake's label said it contained 620 0r 140 calories. Moreover, the participants reported feeling more full when they thought they'd consumed a higher-calorie shake.      What does this means for our eating habits? Although it hardly seems practical to trick ourselves in to eating less, the new findings do highlight the benefits of focusing on our food avoiding TV and multitasking while eating.   ... Question: What is said to be a factor affecting our appetite and food intake? Options: A: How we perceive the food we eat. B: What ingredients the food contains. C: When we eat our meals. D: How fast we eat our meals.
