Read the following passage and mark the letter A, B, C or D to indicate the correct answer to each of the questions:

It is commonly believed in the United States that school is where people go to get an education. Nevertheless, it has been said that today children interrupt their education to go to school. The distinction between schooling and education implied by this remark is important. Education is much more open-ended and all-inclusive than schooling. Education knows no bounds. It can take place anywhere, whether in the shower or on the job, whether in a kitchen or on a tractor. It includes both the formal learning that takes place in schools and the whole universe of informal learning. The agents of education can range from a revered grandparent to the people debating politics on the radio, from a child to a distinguished scientist. Whereas schooling has a certain predictability, education quite often produces surprises. A chance conversation with a stranger may lead a person to discover how little is known of other religions. People are engaged in education from infancy on. Education, then, is a very broad, inclusive term. It is a lifelong process, a process that starts long before the start of school and one that should be an integral part of one’s entire life. Schooling, on the other hand, is a specific, formalized process, whose general pattern varies little from one setting to the next. Throughout a country, children arrive at school at approximately the same time, take assigned seats, are taught by an adult, use similar textbooks, do homework, take exams, and so on. The slices of reality that are to be learned, whether they are the alphabet or an understanding of the workings of government, have usually been limited by the boundaries of the subject being taught. For example, high school students know that they are not likely to find out in their classes the truth about political problems in their communities or what the newest filmmakers are experimenting with. There are definite conditions surrounding the formalized process of schooling.

It was once believed that being overweight was healthy, but nowadays few people subscribe to this view point. While many people are fighting the battle to reduce weight, studies are being conducted concerning the appetite and how it is controlled by both emotional and biochemical factors. Some of the conclusion of these studies may give insight into how to deal with weight problems. For example, when several hundred people were asked about their eating habits in times of stress, 44 percent said they reacted to stressful situations by eating. Further investigations with both humans and animals indicated that it is not food which relieves tension but rather the act of chewing. A test in which subjects were blindfolded showed that obese people have a keener sense of taste and crave more flavor food than non-obese people. When deprived of the variety and intensity of tastes, obese people are not satisfied and consequently eat more to fulfill this need. Blood samples taken from these people after they were shown a picture of food revealed that overweight people reacted with an increase in blood insulin, a chemical associated with appetite. This did not happen with average-weight people. In another experiment, results showed that certain people have a specific, biologically induced hunger for carbohydrates. Eating carbohydrates raises the level of serotonin, a neurotransmitter in the brain. Enough serotonin produces a sense of satiation, and hunger for carbohydrates subsides. Exercise has been recommended as an important part of a weight-loss program. However, it has been found that mild exercises, such as using stairs in stead of the elevator, is better in the long run than taking on a strenuous program, such as jogging, which many people find difficult to continue over periods of time and which also increase appetite.

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 that follow:

Becoming a teacher demands not only knowledge in an academic field but also a personal commitment to lifelong learning, and enthusiasm for sharing knowledge with other people. To become one of those noble educators in the USA, one has to satisfy several basic requirements. First and foremost, it is a prerequisite to have bachelor's degree in education. In the event that a candidate already has a bachelor's degree in another field, a teacher preparation program is needed. But that is not all. Almost every school in the USA understands that real classroom teaching experience is a vital part of a teacher's training. Before taking over a class, a person typically needs to complete a training program, including working as a supervised student teacher. People who want to become university teachers need master's degrees. Getting a master's degree is a necessity, but if it is gained too early, there may be concerns that the candidate lacks the real-world experience to go with it. In fact, very few schools want to hire novices with little or no classroom experience and even if they are accepted, they are usually ill-paid. One wise solution to the issue is for future postgraduates to start working as teachers before going on to gain their master's degree. Besides knowledge and experience, certain personal qualities are also required. A teacher should be positive, prepared, focused, and most importantly, patient. Being a teacher involves being aware of the fact that learning sometimes be hard work, even for the most motivated students. Also, teaching can at times be tiring and frustrating, so teaching candidates have to practice being patient with themselves. In short, as in other careers, teaching requires a combination of qualifications, experience, and personal qualities. Teaching candidates meeting mandatory requirements are always in demand in the USA.
