Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the questions from 28 to 34.         During the second half of the nineteenth century, the production of food and feed crops in the United States rose at an extraordinarily rapid rate. Com production increased by four and a half times, hay by five times, oats and wheat by seven times. The most crucial factor behind this phenomenal upsurge in productivity was the widespread adoption of labor-saving machinery by northern farmers. By 1850 horse-drawn reaping machines that cut grain were being introduced into the major grain-growing regions of the country. Horse-powered threshing machines to separate the seeds from the plants were already in general use. However, it was the onset of the Civil War in 1861 that provided the great stimulus for the mechanization of northern agriculture. With much of the labor force inducted into the army and with grain prices on the rise, northern farmers rushed to avail themselves of the new labor-saving equipment. In 1860 there were approximately 80,000 reapers in the country; five years later there were 350,000.         After the close of the war in 1865, machinery became ever more important in northern agriculture, and improved equipment was continually introduced. By 1880 a self-binding reaper had been perfected that not only cut the grain, but also gathered the stalks and bound them with twine. Threshing machines were also being improved and enlarged, and after 1870 they were increasingly powered by steam engines rather than by horses. Since steam-powered threshing machines were costly items-running from $ 1,000 to $4,000 - they were usually owned by custom thresher owners who then worked their way from farm to farm during the harvest season. “Combines” were also coming into use on the great wheat ranches in California and the Pacific Northwest. These ponderous machines - sometimes pulled by as many as 40 horses - reaped the grain, threshed it, and bagged it, all in one simultaneous operation.           The adoption of labor-saving machinery had a profound effect upon the sale of agricultural operations in the northern states-allowing farmers to increase vastly their crop acreage. By the end of century, a farmer employing the new machinery could plant and harvest two and half times as much com as a farmer had using hand methods 50 years before. The word “crucial” in paragraph 1 is closest in meaning to _________.

Read the following passage and mark the letter A, B, c, or D on your answer sheet to indicate the correct answer to each of the questions. In 1988, Canadian athlete Ben Johnson set a new world record for the 100 metres sprint and set the Seoul Olympics alight. Just a few days later, he was stripped of his medal and banned from competing after having failed a drug test, highlighting what has since become an international problem - drug use in sport. Those involved in sports face enormous pressure to excel in competition, all the more so as their careers are relatively short. By the time most sportspeople are in their forties, they are already considered to be past their prime, and as a result they need to earn their money as quickly as possible. In such a high-pressure environment, success has to come quickly and increasingly often drugs are playing a prominent role. There are a number of specific effects that sportspeople are aiming to achieve by taking performance­enhancing drugs. Caffeine and cocaine are commonly used as stimulants, getting the body ready for the mass expenditure of energy required. In addition, there are those who are looking to build their body strength and turn to the use of anabolic steroids. Having worked so hard and needing to unwind, sportspeople may misuse other drugs as a relaxant in that it can help them cope with stress or boost their own confidence. Alcohol is commonly used for this purpose, but for sportspeople something more direct is often required, and this has led to an increase in the use of beta-blockers specifically to steady nerves. Increasingly accurate drug testing is leading companies and suppliers to ever-more creative ways of avoiding detection, and there are a range of banned substances that are still taken by sportspeople in order to disguise the use of other, more potent drugs. Diuretics is a good example of this: in addition to allowing the body to lose excess weight, they are used to hide other substances. Drugs or not, the working life of the average sportsperson is hard and often painful. Either through training or on the field, injuries are common and can lead to the use of narcotics simply to mask the pain. There are examples of champion motorcyclists taking local anaesthetics to hide the pain of a crash that should have seen them taken straight to hospital, and though this is not directly banned, use is carefully monitored. Drug testing has since become an accepted feature of most major sporting events, and as soon as a new drug is detected and the user is banned from competitive sport, then a new drug is developed which evades detection. Inevitably, this makes testing for such banned substances even more stringent, and has in recent years highlighted a new and disturbing problem - the unreliability of drug tests. Recent allegations of drug use have seen sportspeople in court attempt to overthrow decisions against them, claiming that they were unaware they had taken anything on the banned list. A test recently carried out saw three non-athletes given dietary substances that were not on the banned list, and the two who didn’t take exercise tested negative. However, the third person, who exercised regularly, tested positive. This, of course, has left the testing of sportspeople in a very difficult position. Careers can be prematurely ended by false allegations of drug abuse, yet by not punishing those who test positive, the door would be open for anyone who wanted to take drugs. The issue is becoming increasingly clouded as different schools of opinion are making themselves heared. There are some that argue that if the substance is not directly dangerous to the user, then it should not be banned, claiming that it is just another part of training and can be compared to eating the correct diet. Ron Clarke, a supporter of limited drug use in sport, commented that some drugs should be accepted as ‘they just level the playing field’. He defended his opinion by pointing out that some competitors have a natural advantage. Athletes bom high above sea level or who work out in high altitudes actually produce more red blood cells, a condition which other athletes can only achieve by dmg taking. Others claim that dmg use shouldn’t be allowed because it contravenes the whole idea of fairly competing in a sporting event, adding that the dmgs available to a wealthy American athlete, for example, would be far superior to those available to a struggling Nigerian competitor. Governing bodies of the myriad of sporting worlds are trying to set some standards for competitors, but as dmg companies become more adept at disguising illegal substances, the procedure is an endless race with no winner. In the face of an overwhelming dmg and supplement market, one thing is certain - dmgs will probably be a significant factor for a long time to come. The text is mainly about____  .
