New surveys suggest that the technological tools we use to make our lives easier are killing our leisure time. We are working longer hours, taking fewer and shorter vacations (and when we do go away, we take our cell phones, PDAs, and laptops along). And, we are more stressed than ever as increased use of e-mail, voice mail, cell phones, and the Internet is destroying any idea of privacy and leisure.
Since the Industrial Revolution, people have assumed that new labor-saving devices would free them from the burdens of the workplace and give them more time to grow intellectually, creatively, and socially -exploring the arts, keeping up with current events, spending more time with friends and family, and even just ''goofing off''.
But here we are at the start of the 21st century, enjoying one of the greatest technological boom times in human history, and nothing could be further from the truth. The very tools that were supposed to liberate us have bound us to our work and study in ways that were inconceivable just a few years ago. It would seem that technology almost never does what we expect.
In 'the old days', the lines between work and leisure time were markedly clearer. People left their offices at a predictable time, were often completely disconnected from and out of touch with their jobs as they traveled to and from work, and were off-duty once they were home. That is no longer true. In today's highly competitive job market, employers demand increased productivity, expecting workers to put in longer hours and to keep in touch almost constantly via fax, cell phones, e-mail, or other communications devices. As a result, employees feel the need to check in on what is going on at the office, oven on days off. They feel pressured to work after hours just to catch up on everything they have to do. Workers work harder and longer, change their work tasks more frequently, and have more and more reasons to worry about job security.
Bosses, colleagues, family members, lovers, and friends expect instant responses to voice mail and e-mail messages. Even college students have become bound to their desks by an environment in which faculty, friends, and other members of the college community increasingly do their work online. Studies of time spent on instant messaging services would probably show staggering use.
This is not what technology was supposed to be doing for us. Now technologies, from genetic research to the Internet, offer all sorts of benefits and opportunities. But, when new tools make life more difficult and stressful rather than easier and more meaningful - and we are, as a society, barely conscious of it - then something has gone seriously awry, both with our expectations for technology and our understanding of how it should benefit us.Which of the following is true, according to the passage?

Ranked as the number one beverage consumed worldwide, tea takes the lead over coffee in both popularity and production with more than 5 million metric tons of tea produced annually. Although much of this tea is consumed in Asia, European and African countries, the United States drinks it fair share. According to estimates by the Tea Council of the United States, tea is enjoyed by no less than half of the U.S population on any given day. Black tea or green tea - iced, spiced, or instant - tea drinking has spurred a billion - dollar business with major tea produces in Africa and South America and throughout Asia.
Tea is made from the leaves of an evergreen plant, Camellia sinensis, which grows tall and lush in tropical regions. On tea plantation, the plant is kept trimmed to approximately four feet high, and as new buds called flush appear, they are plucked off by hand. Even in today's world of modern agricultural machinery, hand harvesting continues to be preferred method. Ideally, only the top two leaves and bud should be picked. This new growth produces the highest quality tea.
After being harvested, tea leaves are laid out on long drying racks, called withering racks, for 18 to 20 hours. During this process, the tea softens and becomes limp. Next, depending on the type of the tea being produced, the leaves may be crushed or chopped to release flavor, and then steamed to retain their green color, and the fermentation process is skipped. Producing black teas requires fermentation during which the tea leaves begin to darken. After fermentation, black tea is dried in vats to produce its rich brown or black color.
No one knows when or how tea became popular, but legend has it that tea as a beverage was discovered in 2737 B.C. by Emperor Shen Nung of China when leaves from Camellia dropped into his drinking water as it was boiling over a fire. As the story goes, Emperor Shen Nung drank the resulting liquid and proclaimed that the drink to be most nourishing and refreshing. Though this account cannot be documented, it is thought that tea drinking probably originated in China and spread to other parts of Asia, then to Europe, and ultimately to America colonies around 1650.
With about half of the caffeine content as coffee, tea is often chosen by those who want to reduce, but not necessarily eliminate their caffeine intake. Some people find that tea is less acidic than coffee and therefore easier on the stomach. Others have become interested in tea drinking since the National Cancer Institute published its findings on the antioxidant properties of tea. But whether tea is enjoyed for its perceived health benefits, its flavor, or as a social drink, teacups continue to be filled daily with the world's most popular beverage.What does the word "they" in paragraph 2 refers to?

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:
Most weddings in Japan start with a religious ceremony in which usually only family members attend. Afterwards, a banquet is customarily held to which many people, including friends and colleagues, are invited. To celebrate the happy occasion, guests give the bride and groom goshuugi – gift money in special envelopes. Goshuugi from friends is usually 20,000 yen or 30,000 yen.
A typical Japanese wedding party starts when the bride and groom enter the banquet hall together, and take their seats on a slightly raised platform facing their guests. Invited guests are seated closer to the bride and groom, with family and relatives seated further in back. The bride's and groom's bosses usually give congratulatory speeches then their friends sing in celebration. Other wedding highlights include a candle ceremony where the couple holds a candle while greeting their guests at each table, and the cutting of the wedding cake. Afterwards, the bride and groom thank their parents with a speech, then leave to end the party.
In the past, dishes that supposedly brought good fortune, such as prawns and sea breams, were served in abundance. So much of the food was ordered that guests ended up taking the surplus home. Today, the majority of the weddings serve just enough for everyone. Additionally, before leaving, guests would traditionally receive souvenir gifts called hikidemono.
Many wedding ceremonies take place at wedding halls or hotels. Rough estimates show that it costs about 3 million yen to host a wedding party for 80 guests. During Japan's economic bubble, overseas weddings and flamboyant receptions with special effects, such as smoke machines and having the bride and groom fly in on gondolas, were very popular. But these days, couples choose to tie the knot in various ways, from not having any ceremony to having a modest affair, or still going all out.According to the passage, goshuugi is .................

Although they are an inexpensive supplier of vitamins, minerals, and high-quality protein, eggs also contain a high level of blood cholesterol, one of the major causes of heart diseases. One egg yolk, in fact, contains a little more than two-thirds of the suggested daily cholesterol limit. This knowledge has caused egg sales to plummet in recent years, which in turn has brought about the development of several alternatives to eating regular eggs. One alternative is to eat substitute eggs. These egg substitutes are not really eggs, but they look somewhat like eggs when they are cooked. They have the advantage of having low cholesterol rates, and they can be scrambled or used in baking. One disadvantage, however, is that they are not good for frying, poaching, or boiling. A second alternative to regular eggs is a new type of egg, sometimes called 'designer' eggs. These eggs are produced by hens that are fed low-fat diets consisting of Ingredients such as canola oil, flax, and rice bran. In spite of their diets, however, these hens produce eggs that contain the same amount of cholesterol as regular eggs. Yet, the producers of these eggs claim that eating their eggs will not raise the blood cholesterol in humans.
Egg producers claim that their product has been portrayed unfairly. They cite scientific studies to back up their claim. And, in fact, studies on the relationship between eggs and human cholesterol levels have brought mixed results. It may be that it is not the type of egg that is the main determinant of cholesterol but the person who is eating the eggs. Some people may be more sensitive to cholesterol derived from food than other people. In fact, there is evidence that certain dietary fats stimulate the body's production of blood cholesterol. Consequently, while it still makes sense to limit one's intake of eggs, even designer eggs, it seems that doing this without regulating dietary fat will probably not help reduce the blood cholesterol level.What has been the cause for changes in the sale of eggs?

Birds that feed in flocks commonly retire together into roosts. The reasons for roosting communally are not always obvious, but there are some likely benefits, In winter especially, it is important for birds to keep warm at night and conserve precious food reserves. One way to do this is to find a sheltered roost. Solitary roosters shelter in dense vegetation or enter a cavity- horned, larks dig holes In the ground and ptarmigan burrow into snow banks- but the effect of sheltering is magnified by several birds huddling together in the roost, as wrens, swifts, brown creepers, bluebirds, and anis do. Body contact reduces the surface area exposed to the cold air, so the birds keep each other warm. Two kinglets huddling together were found to reduce their heat losses by a quarter and three together saved a third of their heat.
The second possible benefit of communal roosts is that they act as "information centers". During the day, parties of birds will have spread out to forage over a very large area. When they return in the evening some will have fed well, but others may have found little to eat. Some investigators have observed that when the birds set out again next morning, those birds that did not feed well on the previous day appear to follow those that did. The behavior of common and lesser kestrels may illustrate different feeding behaviors of similar birds with different roosting habits. The common kestrel hunts vertebrate animals in a small, familiar hunting ground, whereas the very similar lesser kestrel feeds on insects over a large area. The common kestrel roost and hunts alone, but the lesser kestrel roosts and hunts in flocks, possibly so one bird can learn from others where to find insect swarms. Finally, there is safety in numbers at communal roosts since there will always be a few birds awake at any given moment to give the alarm. But this increased protection is partially counteracted by the fact that mass roosts attract predators and are especially vulnerable if they are on the ground. Even those in trees can be attacked by birds of prey. The birds on the edge are at greatest risk since predators find it easier to catch small birds perching at the margins of the roost

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.
Fungi are a group of organisms that, despite being plants, have no leaves or flowers. In fact, fungi do not even share the green colour that most other plants display. Scientists estimate that there are over 1.5 million different species of fungi in the world. Though, to date, only 100.000 have been identified, leaving many more that have not been found. One interesting feature of fungi is that they often interact with oilier organisms in order to survive. These relationships are at times beneficial to both organisms. Other times, the fungus benefits without causing harm to the other organism.
Many types of fungus have beneficial relationships with plants. Initially many gardeners would be concerned to know that their plants were colonised by a fungus. This is because some fungi can cause plants to die. In fact, the Irish potato famine was caused by a fungus that killed entire crops of potatoes. However, many plants actually depend on certain types of fungi to help it stay healthy. Fungi are important to plants because they help plants absorb more minerals from the soil than they could on their own. The reason for this has to do with how fungi obtain food. Unlike green plants, fungi cannot make their own food. They must absorb their food. When the fungi absorb minerals from the soil, they draw the nutrients closer to the roots of the plants, so the plant is able to use them as well. The fungus also benefits from this relationship. Using the minerals from the soil, as well as sunlight, the plants is able to produce sugars and other nutrients. Then the fungus absorbs the nutrients from plant roots and uses them to survive.
Not all relationships are beneficial for both organisms: in some interactions, only the fungus benefits. Still, for some fungus species, contact with other organisms is essential. And though the fungi do not provide any benefits for the other organism, they do not harm it either. One example of this is a species called Pilobolus. This fungus relies on other animals to help it reproduce. The Pilobolus grows in animal dung. When it becomes mature, it shoots its spores away from the dung pile. The spores land in the grass where cows graze. The spores are consumed by the animal but do not grow while inside the stomach. They travel through the body of the animal until they are passed and deposited in another area, where they continue to grow.
The word "absorb" in the passage 2 is closest in meaning to_________.

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:
Humans are bringing about another global-scale change in the atmosphere: the increase in what are called greenhouse gases. Like glass in a greenhouse, these gases admit the Sun's light but tend to reflect back downward the heat that is radiated from the ground below, trapping heat in the Earth's atmosphere. This process is known as the greenhouse effect. Carbon dioxide is the most significant of these gases – there is 25 percent more carbon dioxide in the atmosphere today than there was a century ago, the result of our burning coal and fuels derived from oil. Methane, nitrous oxide, and CFCs are greenhouse gases as well.
Scientists predict that increases in these gases in the atmosphere will make the Earth a warmer place. They expect a global rise in average temperature somewhere between 1.0 and 3.5 degrees Celsius in the next century. Average temperatures have in fact been rising and the years from 1987 to 1997 were the warmest years on record. Some scientists are reluctant to say that global warming has actually begun because climate naturally varies from year to year and decade to decade, and it takes many years of records to be sure of a fundamental change. There is little disagreement, though, that global warming is looming.
Global warming will have different effects in different regions. A warmed world is expected to have more extreme weather, with more rain during wet periods, longer droughts, and more powerful storms. Although the effects of future climate changes are unknown, some predict that exaggerated weather conditions may translate into better agricultural yields in areas such as the western United States, where temperature and rainfall are expected to increase, while dramatic decreases in rainfall may lead to severe droughts and plunging agricultural yields in parts of Africa, for example.
Warmer temperatures are expected to partially melt the polar ice caps, leading to a projected sea level rise of 50 centimeters by the year 2050. A sea level rise of this magnitude would flood coastal cities, force people to abandon low-lying islands, and completely inundate coastal wetlands. Diseases like malaria, which at present are primarily found in the tropics, may become more common in the regions of the globe between the tropics and the polar regions, called the temperate zones. For many of the world's plant species, and for animal species that are not easily able to shift their territories as their habitat grows warmer, climate change may bring extinction.According to paragraph 1, which of the following factors causes an increase in greenhouse gases?

During the seventeenth and eighteenth centuries, almost nothing was written about the contributions of women during the colonial period and the early history of the newly formed United States. Lacking the right to vote and absent from the seats of power, women were not considered an important force in history. Anne Bradstreet wrote some significant poetry in the seventeenth century, Mercy Otis Warren produced the host contemporary history of the American Revolution, and Abigail Adams penned Important letters showing she exercised great political Influence over her husband, John, tiie second President of the United States. But little or no notice was taken of these contributions. During those centuries, women remained Invisible In history books.
Throughout the nineteenth century, this lack of visibility continued, despite the efforts of female authors writing about women, These writers, like most of their male counterparts, were amateur historians. Their writings were celebratory in nature, and they were uncritical in their selection and use of sources.
During the nineteenth century, however, certain feminists showed a keen sense of history by keeping records of activities in which women were engaged. National, regional, and local women's organizations compiled accounts of their doings. Personal correspondence, newspaper clippings, and souvenirs were saved and stored. These sources from the core of the two greatest collections of women’s history In the United States one at the Elizabeth and Arthur Schleslnger Library at Radcliffe College, and the other the Sophia Smith Collection at Smith College. Such sources have provided valuable materials for later Generations of historians.
Despite the gathering of more information about ordinary women during the nineteenth Century, most of the writing about women conformed to the "great women" theory of History, just as much of mainstream American history concentrated on "great men," To demonstrate that women were making significant contributions to American life, female authors singled out women leaders and wrote biographies, or else important women produced their autobiographies. Most of these leaders were Involved in public life as reformers, activists working for women's right to vote, or authors, and were not representative at all of the great of ordinary woman. The lives of ordinary people continued, generally, to be untold in the American histories being published.In the 2nd paragraph, what weakness in nineteenth-century histories does the author point out?

Picture a society where learning can happen at any time, in any place and can be completed without ever going to class. This is could be new wave of education and the internet technology now exists to support such a system. The virtual classroom is here. If you are interested in English or Civil Engineering, then head to the University and click yourself a degree. Well, maybe it’s not that easy, but you would be on the right track. The flexibility of studying at your own pace, and the money you save with online courses, are two of the main attractions.
The web is a powerful educational tool. Some feel that virtual classrooms will isolate students from each other, which will result in problems developing interpersonal relationships and that these skills are much more important than computer skills. Should teachers teach kids how to behave in society, how to respect others and how to co-operate, or should kids have already learned this from their parents? No one is saying that social skills aren’t important, however, virtual classrooms are far more than just computer skills. Some strongly believe that education can be taught via the web and social skills can be gained from joining sports teams, summer camps, or just by hanging out! Others argue that this virtual classroom may place pressure on students: to become computer literate or be left behind in life. Is this undue pressure or reality? Maybe being left behind in life is a little dramatic, but the reality is that the computer age is here. Whether you want to pay for your new jeans with your debit card, or check to see if the library has the book you want, you’re going to need some computer skills.
The development of flexible, inquiring minds has rarely been the main concern in the design of educational systems. After all, if you have over thirty inquiring minds and only one teacher, flexibility could be a problem. It seems that developing students’ proper social behavior has always exceeded the concern to develop students’ creativity. Computer technology can make individualized attention a real possibility. At the Institute for the Learning Sciences, systems are being developed to allow people to try out things in simulated worlds. This technology will allow for the individual creative growth in students.
The web will provide amazing opportunities for the education of our society. Anyone with a computer and internet access can peruse effectively unlimited amounts of knowledge and programs, designed to help them learn and understand. The teachers and parents involved with these programs will be given the job of making sure that students lead well-balanced lives that combine Web-education and positive social interaction with their friends and neighbors. Imagine that your recreation room has now become your classroom, and your parents seem to be doing as much homework as you are! So, be prepared as the virtual classroom may find its way to a computer screen near you!
What is the author’s overall attitude towards a virtual classroom?

Read the following passage and mark the letter A, B, C or D to indicate the correct answer to each of the questions.
The increase in urbanization causes different problems. Air and water pollution are amongst the major issue we have to tackle.
In the first place, cars, factories and burning waste emit dangerous gases that change the air quality in our cities and pose threats to our health. Dangerous gases such as carbon dioxide and nitrogen oxides cause respiratory diseases, for instant, bronchitis and asthma. Those are also proved to have long-term effects on the environment.
Furthermore, with the increased population, it becomes difficult to manage the waste generated in cities. Most of the waste is discharged or dumped into rivers or onto streets. The waste pollutes water and makes it unfit for human consumption. Subsequently, it becomes more and more difficult for city dwellers to get clean water. Some cities in Africa are unable to provide adequate water supply because most of the water is lost in pipe leakages. In fact, most city dwellers in developing countries are forced to boil their water or to buy bottled water, which is very expensive.
There are several actions that could be taken to eradicate the problems described above. Firstly, a simple solution would be joining community efforts to address problems affecting your city. Ask your parents, friends and relatives to join in as well. These efforts might include clean-up campaigns, recycling projects and a signature campaign to ask the government to do something about the situation. A second measure would be encouraging your teacher to talk about these problems and to discuss how young people can help to solve them. Finally, writing to local organizations working on these issues for ideas on how you can contribute to solve them.

PANDEMIC DISEASES
Diseases are a natural part of life on earth. If there were no diseases, the population would grow too quickly, and there would not be enough food or other resources, so in a way, diseases are natural ways of keeping the Earth in balance. But sometimes they spread very quickly and kill large numbers of people. For example, in 1918, an outbreak of the flu spread across the world, killing over 25 million people in only six months. Such terrible outbreaks of a disease are called pandemics.
Pandemics happen when a disease changes in a way that our bodies are not prepared to fight. In 1918, a new type of flu virus appeared. Our bodies had no way to fight this new flu virus, and so it spread very quickly and killed large numbers of people. While there have been many different pandemic diseases throughout history, all of them have a new thing in common.
First, all pandemic diseases spread from one person to another very easily.
Second, while they may kill many people, they generally do not kill people very quickly. A good example of this would be the Marburg virus. The Marburg virus is an extremely infectious disease. In addition, it is deadly. About 70 -80% of all people who get the Marburg virus died from the disease. However, the Marburg virus has not become a pandemic because most people die within three days of getting the disease. This means that the virus does not have enough time to spread a large number of people. The flu virus of 1918, on the other hand, generally took about a week to ten days to kill its victims, so it had more time to spread.
While we may never be able to completely stop pandemics, we can make them less common. Doctors carefully monitor new diseases that they fear could become pandemics. For example, in 2002, and 2003, doctors carefully watched SARS. Their health warnings may have prevented SARS from becoming a pandemic.According to the passage, all of the following are true of the 1918 flu pandemic EXCEPT that ..............

Read the following passage, then choose the correct answer to questions 31 - 35.
Smoking causes lung cancer, which is the number one cancer among men. Ninety percent of the people who get lung cancer die. Smoking is also the leading cause of mouth cancer, tongue cancer, and throat cancer. Many smokers have heart disease arid pneumonia. Smoking causes one million early deaths in the world every year.
Smokers not only harm themselves but also harm others. Smokers breathe smoke out into the air. They breathe it out on their children and their wives or husbands. Children whose parents smoke have more breathing and lung problems than other children. Women who are married to smokers are more likely to have lung cancer than those married to non- smokers.
We are all aware that smoking is bad. So why do people smoke?Who are more likely to have lung cancer and lung problems?

Read the passage carefully and choose the correct answer
On 8 August 1967, five leaders - the Foreign Ministers of Indonesia, Malaysia, the Philippines, Singapore and Thailand- sat down together in the main hall of the Department of Foreign Affairs building in Bangkok, Thailand and signed a document. By virtue of that document, the Association of Southeast Asian Nations (ASEAN) was born. The five Foreign Ministers who signed it have been considered as the founders of probably the most successful intergovernmental organization in the developing world today. The document that they signed would be known as the ASEAN Declaration.
It is a short, simply-worded document containing just five articles. It declares the establishment of an Association for Regional Cooperation among the Countries of Southeast Asia to be known as the Association of Southeast Asian Nations (ASEAN) and spells out the aims and purposes of that Association. These aims and purposes are about the cooperation in economy, society, culture, techniques, education and other fields, and in the promotion of regional peace and stability through abiding respect for justice and the principles of the United Nations Charter. It stipulates that the Association will be open for participation by all States in the Southeast Asian region subscribing to its aims, principles and purposes. It proclaims ASEAN as representing the collective will of the nations of Southeast Asia to bind themselves together in friendship and cooperation and, through joint efforts and sacrifices, secure for their peoples and for posterity the blessings of peace, freedom and prosperity. The goal of ASEAN, then, is to create, not to destroy.
The original ASEAN logo presented five brown sheaves of rice stalks, one for each founding member. Beneath the sheaves is the legend "ASEAN" in blue. These are set on a field of yellow encircled by a blue border. Brown stands for strength and stability, yellow for prosperity and blue for the spirit of cordiality in which ASEAN affairs are conducted. When ASEAN celebrated its 30th Anniversary in 1997, the sheaves on the logo had increased to ten -representing all ten countries of Southeast Asia and reflecting the colors of the flags of all of them. In a very real sense, ASEAN and Southeast Asia will be one and the same, just as the founders had envisioned.
Which adjective can be used to describe the Association of Southeast Asian Nations?

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.
Many flowering plants woo insect pollinators and gently direct them to their most fertile blossoms by changing the color of individual flowers from day to day. Through color cues, the plant signals to the insect that it would be better off visiting one flower on its bush than another. The particular hue tells the pollinator that the flower is full of far more pollen than are neighboring blooms. That nectar-rich flower also happens to be fertile and ready to disperse its pollen or to receive pollen the insect has picked up from another flower. Plants do not have to spend precious resources maintaining reservoirs of nectar in all their flowers. Thus, the color-coded communication system benefits both plants and insects.
For example, on the lantana plant, a flower starts out on the first day as yellow, when it is rich with pollen and nectar. Influenced by an as-yet-unidentified environmental signal, the flower changes color by triggering the production of the pigment anthromyacin. It turns orange on the second day and red on the third. By the third day, it has no pollen to offer insects and is no longer fertile. On any given lantana bush, only 10 to 15 per cent of the blossoms are likely to be yellow and fertile. But in tests measuring the responsiveness of butterflies, it was discovered that the insects visited the yellow flowers at least 100 times more than would be expected from haphazard visitation. Experiments with paper flowers and painted flowers demonstrated that the butterflies were responding to color cues rather than, say, the scent of the nectar.
In other types of plants, blossoms change from white to red, others from yellow to red, and so on. These color changes have been observed in some 74 families of plants.
The first paragraph of the passage implies that insects benefit from the color-coded communication system because __________

PANDEMIC DISEASES
Diseases are a natural part of life on earth. If there were no diseases, the population would grow too quickly, and there would not be enough food or other resources, so in a way, diseases are natural ways of keeping the Earth in balance. But sometimes they spread very quickly and kill large numbers of people. For example, in 1918, an outbreak of the flu spread across the world, killing over 25 million people in only six months. Such terrible outbreaks of a disease are called pandemics.
Pandemics happen when a disease changes in a way that our bodies are not prepared to fight. In 1918, a new type of flu virus appeared. Our bodies had no way to fight this new flu virus, and so it spread very quickly and killed large numbers of people. While there have been many different pandemic diseases throughout history, all of them have a new thing in common.
First, all pandemic diseases spread from one person to another very easily.
Second, while they may kill many people, they generally do not kill people very quickly. A good example of this would be the Marburg virus. The Marburg virus is an extremely infectious disease. In addition, it is deadly. About 70 -80% of all people who get the Marburg virus died from the disease. However, the Marburg virus has not become a pandemic because most people die within three days of getting the disease. This means that the virus does not have enough time to spread a large number of people. The flu virus of 1918, on the other hand, generally took about a week to ten days to kill its victims, so it had more time to spread.
While we may never be able to completely stop pandemics, we can make them less common. Doctors carefully monitor new diseases that they fear could become pandemics. For example, in 2002, and 2003, doctors carefully watched SARS. Their health warnings may have prevented SARS from becoming a pandemic.Which of the following is mentioned as a common feature of all pandemic diseases?

Read the following passage and mark the letter A, B, C or D to indicate the correct answer to each of the questions.
Born on June 30, 1985 in Baltimore, Maryland, to Fred and Debbie Phelps, the youngest of three children, Michael Phelps and his sisters grew up in the neighbourhood of Rodger Forge. His father, Fred, a former all-rounded athlete, was a state trooper and his mother Debbie was a middle-school principal. When Phelps's parents divorced in 1994, he and his siblings lived with their mother, with whom Michael grew very close. Even at the age of 7, Phelps was still a little scared to put his head under water, so his instructors allowed him to float around on his back. Not surprisingly, despite the fact that later he is very good at butterfly swimming, the first stroke he mastered was not the easily-practised breaststroke but the backstroke.
At the age of 15, Phelps became the youngest American male swimmer to compete at an Olympic Games in 68 years. While he didn't win any medals at the 2000 Summer Olympics in Sydney, Australia, he would soon become a major force in competitive swimming.
In the spring of 2001, Phelps set the world record in the 200-meter butterfly, becoming the youngest male swimmer in history at the age of 15 years and 9 months. At the 2001 World Championships in Japan, he then broke his own record with a time of 1:54:58, earning his first international medal. In 2002, Phelps continued to establish several records including the 100-meter butterfly and the 200-meter individual medley. The following year, at the same event, he broke his own world record in the 400-meter individual medley with a time of 4:09.09.
After the London Olympics in 2012, Phelps announced he was retiring from his sport. However, at the 2016 Olympic Games, he came out of retirement and returned to professional competition. This was also the event in which he won one silver and five gold medals, becoming the oldest individual gold medalist in Olympic swimming history, as well as the first swimmer to win four consecutive golds in the same event, the 200 meter individual medley.
The first style of swimming Phelps was good at is ____.
