Read the following passage and mark the letter A, B, C, or D to indicate the correct answer to each of the questions from 35 to 42   OBESITY: SHRINKING THE WORLD'S WAISTLINE      For most of human history, the majority of the world's population struggled to get enough food. Although starvation is also a big issue in some countries, many nations are now facing the opposite problem - people are consuming too much food. In the past few decades, obesity has become a global concern that physicians around the globe are trying to deal with.        Obesity occurs when a person becomes so overweight that their extra weight starts to endanger their health. Many experts believe that the rise of obesity is closely linked to the rise of cheap, high-calorie foods that bring little health benefits. These foods often contain lots of salt, sugar, and fat. But this is not the only reason that people are getting heavier. In addition to poor food choices, people are burning fewer calories because their lives have become lazier and they don't get enough exercise.        There is no denying that the statics are alarming. Since 1980, the world's obesity rate has almost doubled. Furthermore, the number of obese people is roughly about equal to the number of people who are underweight. This increasing obesity rate has led to skyrocketing health care costs in several countries. Obesity has been shown to increase the risks of several deadly diseases. This includes heart disease, some forms of cancer, and diabetes.        Dealing with obesity has proven to be more difficult than originally anticipated. This is because there are many factors which contribute to people becoming obese. First, if you walk through any supermarket, you will find many more processed foods than fresh ones like fruits and vegetables. Although these processed foods are void of nutrition, they are much cheaper and easier to prepare than fresh foods. Corporate marketing campaigns make things worse, as companies that sell junk foods will spend millions of dollars to convince consumers to buy their foods without mentioning that they are unhealthy.        Some people are fighting back obesity though, including the former US First Lady Michelle Obama. She has started an organization called Let's Move that specifically targets childhood obesity. The organization believes in educating students, parents, and educators about how to prepare healthy foods and showing them fun ways to get exercise. Let's Move also works closely with schools to ensure that nutritious and affordable meals are provided in schools, so the process of staying in shape won't be difficult. Although we are a long way from defeating the obesity problem, programs like this one are a good start.  What is the passage mainly about?

Read the following passage and mark the letter A, B, C, or D to indicate the correct answer to each of the questions from 30 to 34        Stars have been significant features in the design of many United States coins and their number has varied from one to forty-eight stars. Most of the coins issued from about 1799 to the early years of the twentieth century bore thirteen stars representing the thirteen original colonies.        Curiously enough, the first American silver coins, issued in, 1794, had fifteen stars because by that time, Vermont and Kentucky had joined the Union. At that time, it was apparently the intention of mint officials to add a star for each new state. Following the admission of Tennessee in 1796, for example, some varieties of half dimes, dimes, and half-dollars were produced with sixteen stars.        As more states were admitted to the Union, however, it quickly became apparent that this scheme would not prove practical and the coins from 1798 on were issued with only thirteen stars-one for each of the original colonies. Due to an error at the mint, one variety of the 1828 half cent was issued with only twelve stars. There is also a variety of the large cent with only 12 stars, but this is the result of a die break and is not a true error.   What is the main topic of the passage?

Read the following passage and mark the letter A, B, C or D on you answer sheet to indicate the correct answer to each of the questions.       The need for a surgical operation, especially an emergency operation, almost always comes as a severe shock to the patient and his family. Despite modern advances, most people still have an irrational fear of hospitals and anesthetics. Patients do not often believe they really need surgery- cutting into a part of the body as opposed to treatment with drugs.       In the early year of the 20" century, there was little specialization in surgery. A good surgeon was capable of performing almost every operation that had been advised up to that time. Today the situation is different. Operations are now being carried out that were not even dreamed of fifty years ago. The heart can be safely opened and its valves repaired. Clogged blood vessels can be cleaned out, and broken ones mended and replaced. A lung, the whole stomach, or even part of the brain can be removed and still permit the patient to live a comfortable and satisfactory life. However, not every surgeon wants to, or is qualified to carry out every type of modern operation.       The scope of surgery has increase remarkable in the past decades. Its safety has increased, too. Deaths from most operations are about 20% of what they were in 1910 and surgery has been extended in many directions, for example, to certain types of birth defects in new born babies, and at the other end of the scale, to life-saving operation for the octogenarian. The hospital stay after surgery has been shortened to as little as a week for most major operations. Most patients are out of bed on the day after an operation and may be back at work in two or three weeks.       One of the most revolutionary areas of modern surgery is that of organ transplants. Until a few decades ago, no person, except an identical twins, was able to accept into his body the tissues of another person without reacting against them and eventually killing them. Recently, however, it has been discovered that with the use of X-rays and special drugs, it is possible to graft tissues from one person to another which will survive for periods of a year or more. Kidneys have been successfully transplanted between non-identical twins. Heart and lung transplants have also been reasonably successful.       "Spare parts" surgery, the simple routine replacement of all worn-out organs by new ones, is still a dream of the future but surgery is ready for such miracles. In the meantime, you can be happy if the doctors say to you: "Yes, I think it is possible to operate on you for this condition".  Today, compared with 1910, __________.
