Read the following article and select the best answer. Article: More than one-third of adults in the United States are obese .In fact,over obesity has reached such proportions that one big-city mayor has gone about banning large-sized,sugary soft drinks and the First Lady has been on a campaign to control the dietary offerings in public schools. Even many adults who do not fit the clinic definition of obesity are still overweight,and a large percentage are looking for the best ways to lose weight. Reducing pounds largely comes down to the two-sided factors of diet and exercise.Not carrying out the first one enough,and not getting enough of the second one,ends up giving the individual a recipe for being overweight. Advising someone to eat less and exercise more might be the easiest advice possible,but it's also,partially,an oversimplification.Dieting has more to do with the types of food you eat than how much you eat.Reduce the amount of red meat in your diet.If you don't want to eliminate red meat altogether,choose cuts of meat with less fat content.Limit your intake of salt and starches.If you've got to have potato chips alongside your sandwich at lunch,choose the baked potato chips that contain less fat than the deep-fried chips.You might find you're really not sacrificing that much in terms of taste. A diet rich in fruits,vegetables,egg whites,fish and nonfat dairy products will certainly aid in the mission of losing weight.Drink more water and less sugary drinks.If you have to have a soda,a diet soda is a better option,but seltzer is an even better choice than that. It's important--if not always easy--to make sure you get at least some physical activity each and every day.If your feet won't allow for a regular jogging regimen,then make sure you take lots of walks.Next time you need to mail a letter,walk to the mailbox instead of driving.Try to work in a daily walk in your neighborhood. Question: You should _ when you want to lose weight - try not to fit the clinic definition of obesity - diet as well as exercise enough - get little exercise every day - focus your attention on diet only
diet as well as exercise enough

(Question)
Read the following article and select the best answer. Article: The latest beliefs are that the main purposes of sleep are to enable the body to rest, allowing time for repairs to take place and for tissue to be regenerated . Lack of sleep, however, can compromise the immune system, cause depression and promote anxiety. For many people, lack of sleep is rarely anything of choice. Some have problems getting to sleep, others with staying asleep until the morning. Despite popular belief that sleep is one long event, research shows that, in an average night, there are five stages of sleep. In the first light stage, the heart rate and blood pressure go down and the muscles relax. In the next two stages, sleep gets progressively deeper. In stage four, usually reached after an hour, the slumber is so deep that, if awoken, the sleeper would be confused and disorientated. It is in this state that sleep-walking can occur, lasting no more than 15 minutes. In the fifth stage, the rapid eye movement (REM) stage, the eyes move constantly beneath closed lids as if the sleeper is looking at something. During this stage, the body is almost paralysed . This REM stage is also the time when we dream.[:Z#xx#k.Com] Sleeping patterns change with age. One theory for the age-related change is that it is due to hormonal changes. The temperature rise occurs at daybreak in the young, but at three or four in the morning in the elderly. Age aside, it is estimated that roughly one in three people suffer some kind of sleep disturbance. Causes can be anything from pregnancy, smoking, and stress to alcohol and heart disease. Apart from self-help therapy such as regular exercise, there are psychological treatments, including relaxation training and therapy aimed at getting rid of pre-sleep worries and anxieties. Medication is regarded by many as a last option and often takes the form of sleeping pills. Question: Which of the following is true to the passage? - Nobody can escape lack of sleep. - A sleep-walker usually dreams before the sleepwalking. - In the REM stage sleepers can see things around but can't move the body. - Regular exercise can better help improve sleep quality than sleeping pills do.
(Answer)
Regular exercise can better help improve sleep quality than sleeping pills do.
