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 43 to 50.          The food we eat seems to have profound effects on our health. Although science has made enormous steps in making food more fit to eat, it has, at the same time, made many foods unfit to eat. Some research has shown that perhaps 80% of all human illnesses are related to diet and 40% of cancer is related to the diet as well, especially cancer of the colon. People of different cultures are more prone to contract certain illnesses because of the characteristic foods they consume.          That food is related to illness is not a new discovery. In 1945, government researchers realized that nitrates and nitrites (commonly used to preserve color in meats) as well as other food additives caused cancer. Yet, these carcinogenic additives remain on our food, and it becomes more difficult all the time to know which ingredients on the packaging labels of processed food are healthful or harmful.          The additives that we eat are not all so direct. Farmers often give penicillin to cattle and poultry, and because of this, penicillin has been found in the milk of treated cows. Sometimes similar drugs are administered to animals not for medicinal purposes, but for financial reasons. The farmers are simply trying to fatten the animals in order to obtain a higher price on the market. Although the Food and Drug Administration (FDA) has tried repeatedly to control these producers, the practices continue.          A healthy diet is directly related to good health. Often we are unaware of detrimental substances we ingest. Sometimes well-meaning farmers or others who do not realize the consequences add these substances to food without their knowledgeAll the following statements are true EXCEPT

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 36 to 42.          Most people go to a doctor in their own town or suburbs. But people in the Australian outback can’t get to a doctor quickly. The nearest doctor is sometimes hundreds of kilometers away so they have to call him on a two-way radio. This special doctor is called the “flying doctor”. He visits sick people by plane.          When someone is sick, the doctor has to fly to the person’s home. His plane lands on a flat piece of ground near the person’s house. Sometimes the doctor has to take the patient to hospital. Flying doctors take about 8,600 people to hospital each year.          However, most of the time the person isn’t very sick, and the doctor doesn’t have to visit. He can give advice on the radio from the office at the flying doctor center. He can tell the patient to use some medicine from a special medicine chest. There is one of these chests in every home in the outback. Each bottle, tube and packet in the chest has a number. The doctor often says something like this, “Take two tablets from bottle number 5 every four hours.”          A man called John Flynn started the Royal Flying Doctor service in 1927. He had only one plane. Today there are 14 flying-doctor centers, 29 planes, 14 full-time doctors and several part- time doctors, nurses and dentists.The writer of this passage shows a/an________attitude to the flying- doctor service

Read the text and answer the questions given by choosing one numbered options.A number of factors related to the voice reveal the personality of the speaker. The first is the broad area of communication, which includes imparting information by use of language, communicating with a group or an individual and specialized communication through performance. A person conveys thoughts and ideas through choice of words, by a tone of voice that is pleasant or unpleasant, gentle or harsh, by the rhythm that is inherent within the language itself, and by speech rhythms that are flowing and regular or uneven and hesitant, and finally, by the pitch and melody of the utterance. When speaking before a group, a person’s tone may indicate uncertainty or fright, confidence or calm. At interpersonal levels, the tone may reflect ideas and feelings over and above the words chosen, or may believe them. Here, the participant’s tone can consciously or unconsciously reflect intuitive sympathy or antipathy, lack of concern or interest, fatigue, anxiety, enthusiasm or excitement, all of which are usually discernible by the acute listener. Public performance is a manner of communication that is highly specialized with its own techniques for obtaining effects by voice and /or gesture. The motivation derived from the text, and in the case of singing, the music, in combination with the performer’s skills, personality, and ability to create empathy will determine the success of artistic, political, or pedagogic communication. Second, the voice gives psychological clues to a person’s self-image, perception of others, and emotional health. Self-image can be indicated by a tone of voice that is confident, pretentious, shy, aggressive, outgoing, or exuberant, to name only a few personality traits. Also the sound may give a clue to the facade or mask of that person, for example, a shy person hiding behind an overconfident front.  How a speaker perceives the listener’s receptiveness, interest, or sympathy in any given conversation can drastically alter the tone of presentation, by encouraging or discouraging the speaker. Emotional health is evidenced in the voice by free and melodic sounds of the happy, by constricted and harsh sound of the angry, and by dull and lethargic qualities of the depressed.The word "drastically" in line 21 is closest in meaning to ___________.
