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 knowledgeWhat is the best title for this passage?

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 word “chest” in this context probably means________
