Which of the following is true, according to the passage?

According to paragraph 2, unhealthy jobs _______ .

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 15 to 19.

Florists, personal trainers, professors, and nutritionists all have healthy jobs according to research. There are many reasons for this. A florist, for example, sells flowers and plants to customers. This is very relaxing work. A personal trainer, on the other hand, is usually very fit. He or she trains other people to lose weight and to keep fit.

However, research also shows that some jobs are 'unhealthy'. They cause a lot of stress and worry. For example, a taxi driver drives all day. He often faces traffic jams and difficult passengers too. A firefighter puts out dangerous fires and sometimes saves people from burning buildings.

Most people are looking for the perfect job. They want a job that is interesting, with a good salary and not much stress. However, it is difficult to get everything. Healthy, relaxing jobs are usually not very well paid. On the other hand, people with stressful jobs often get good salaries. For example, the head of a big company gets a lot of money, but he or she does not always have good health, or the time to enjoy life.

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 6 to 12

Three scales of temperature, each of which permits a precise measurement, are in current use: the Fahrenheit, Celsius, and Kelvin scales. These three different temperature scales were each developed by different people and have come to be used in different situations.

The scale that is most widely used by the general public in the United States is the Fahrenheit scale. In 1714, Daniel Gabriel Fahrenheit, a German physicist who was living in Holland and operating an instrument business, developed a thermometer and the temperature scale that still carries his name. His original scale had two fixed points: 0° was the lowest temperature and 96° was what he believed was the normal temperature of the human body. Based on this scale, he calculated that the freezing point of water was 32° in later studies, it was determined that the boiling point of water was 212°. The Fahrenheit scale came to be accepted as the standard measure of temperature in a number of countries. Today, however, the United States is the only major country in the world that still uses the Fahrenheit scale.

The scale that is in use in many other countries is the Celsius scale. Anders Celsius, a Swedish astronomer, developed a thermometer in 1741 that based temperatures on the freezing and boiling temperatures of water. On the thermometer that Celsius developed, however, 0° was used to indicate the boiling temperature of water, and 100° was used to indicate the freezing temperature of water. After his death, the scale was reversed by a friend, the biologist Carl von Linne. On the new scale after the reversal by von Linne, O indicated the freezing temperature of water, and 100° indicated the boiling temperature of water. At around the same time, a similar thermometer was being developed in France. After the French Revolution, the scale developed in France was adopted as part of the metric system in that country under the name centigrade, which means "a hundred units," and from there it spread worldwide. In 1948, an international agreement was made to rename the centigrade scale the Celsius scale in honor of the scientist who was first known to use a 100-degree scale, though it should be remembered that the scale that Celsius actually used himself was the reverse of today's scale.

A third scale, the Kelvin scale, is generally used today for scientific purposes. This scale was first suggested in 1854 by two English physicists: William Thomson, Lord Kelvin and James Prescott Joule. The Kelvin scale defines 0° as absolute zero, the temperature at which all atomic and molecular motion theoretically stops, and 100° separates the freezing point and boiling point of water, just as it does on the Celsius scale. On the Kelvin scale, with 0° equal to absolute zero, water freezes at 273°, and water boils at a temperature 100° higher. The Kelvin scale is well suited to some areas of scientific study because it does not have any negative values, yet it still maintains the 100° difference between the freezing point and boiling point of water that the Celsius scale has and can thus easily be converted to the Celsius scale by merely subtracting 273° from the temperature on the Kelvin scale.

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 following questions from 39 to 43.

Can you imagine waking up each day in a house that is gently rocked by the movement of water, having a water park as a garden and getting to work by water taxi? Well, for some people this vision of the future may become a reality. It is a commonly accepted fact that as the Earth’s temperature rises, the ice caps at the North and South Poles will melt, causing the sea level to rise.

So, where does this leave the many countries in the world which have large sections of their populations living in areas which lie at or below sea level? The Netherlands, for example, is one of the most highly populated, low-lying countries in the world and has been battling with the problem of flooding for years. Further rises in the sea level would mean much of the country will disappear under water.

Inventive architects may have come up with a solution to the problem: a floating house actually built on the water. The basic idea is that houses will have a base filled with air and a way of anchoring them to the ground. This will allow the houses to float upwards whenever the sea level rises and sink back down when the sea level drops. So, are floating houses the homes of the future? For some people there may be no alternative; for others it will be through choice. After all, who says you have to live on dry land anyway?
