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.

When the first white men came to America, they found vast amounts of natural resources of tremendous value. Forests covered a large part of the nation; later gas, oil and minerals were found in unbelievable amounts. There was a great abundance of very fertile soil. Forests, prairies, streams and rivers abounded with wildlife. So vast were these resources that it seemed that they could never be used up. So forests were destroyed to make way for farmland. Grasslands and prairies were ploughed and harrowed. Minerals and oil were used in great quantities to supply a young industrial nation. Almost every river became the scene of factories, mills and power companies. Mammals and birds were slaughtered for food and sport.

Within a short time, the results were obvious. Floods caused millions of dollars worth of damage yearly. The very fertile soil was washed away or blown up in great clouds. The seemingly inexhaustible oil and minerals showed signs of depletion. Rivers were filled with silt from eroding farms and wastes from factories. Many of the rivers were made unfit for fish. Several species of birds disappeared, and some mammals seemed on the verge of going. Future timber shortages were predicted. In short, Americans soon became to realize that some sort of conservation program must be set up, if future as well as present Americans were to share in the resources that are the heritage of every American.

According to the passage, all the following are true EXCEPT_____- 

A. They plowed ;and harrowed grasslands and prairies

B. They killed animals for food and sport

C. The early American settlers used a lot of minerals and oil

D. They grew different kinds of plants in prairies

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.

Vitamins, taken in tiny doses, are a major group of organic compounds that regulate the mechanisms by which the body converts food into energy. They should not be confused with minerals, which are inorganic in their makeup. Although in general the naming of vitamins followed the alphabetical order of their identification, the nomenclature of individual substances may appear to be somewhat random and disorganized. Among the 13 vitamins known today, five are produced in the body. Because the body produces sufficient quantities of some but not all vitamins, they must be supplemented in the daily diet. Although each vitamin has its specific designation and cannot be replaced by another compound, a lack of one vitamin can interfere with the processing of another. When a lack of even one vitamin in a diet is continual, a vitamin deficiency may result.

The best way for an individual to ensure a necessary supply of vitamins is to maintain a balanced diet that includes a variety of foods and provides adequate quantities of all the compounds. Some people take vitamin supplements, predominantly in the form of tablets. The vitamins in such supplements are equivalent to those in food, but an adult who maintains a balanced diet does not need a daily supplement. The ingestion of supplements is recommended only to correct an existing deficiency due to unbalanced diet, to provide vitamins known to be lacking in a restricted diet, or to act as a therapeutic measure in medical treatment. Specifically, caution must be exercised with fat-soluble substances, such as vitamins A and D, because, taken in gigantic doses, they may present a serious health hazard over a period of time.

According to the passage, vitamins are

A. food particles 

B. essential nutrients

C. miscellaneous substances

D. major food groups

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.
