Mark the letter to indicate the correct answer to each of the following questions.

Some shops advertise their products and services in the newspaper to ______ customers.

Milpa Alta is a region of twelve villages and towns to the south of Mexico City. In Milpa Alta, traditions are still very important and one of the most famous traditional events is a community meal. It takes place every Christmas and is called La Rejunta. More than a meal, it’s a feast, where about sixty thousand tamales and fifteen thousand litres of hot chocolate are made and consumed. Tamales are made from corn. They are typical of the region: the name Milpa Alta means ‘High cornfield’. The feast is offered to the people who go on the long walk to El Señor de Chalma about 80 kilometers away. It’s an important event on the religious calendar for local people and as many as 20,000 people take part. 
The planning and organisation of La Rejunta takes the whole year. Every year, different people are given the job of majordomo, which means they’re responsible for organising the meal. There’s a waiting list for the opportunity to do this and currently the next available year is 2046. This year’s majordomos are Virginia Meza Torres and her husband Fermín Lara Jiménez, who put their names on the list 14 years ago. 
One year before the meal, men go to the forest and collect wood that they store near the home of the majordomo. It has to be dry when it’s used to make the cooking fires. Local farmers grow most of the corn, meat and vegetables that are needed as ingredients. In the week before the feast, hundreds of volunteers arrive to help with the preparation and the cooking. No instant or ready-made foods are allowed. Amazingly, everyone seems to know what they have to do. On the day of the feast, the majordomos and others have stayed up all night cooking. Fermin is in charge of the numbers – making sure there are enough tamales for everyone. 
For the people of Milpa Alta, eating together is one of their most important traditions. One woman, Josefina García Jiménez, explains that sitting together at the table is like a glue that keeps people together. ‘It feels like I am passing down a tradition, and when they are adults, they will remember what I have done. Here we have time to cook, time to think about the ingredients, time to show our kids through cooking that we love them.’ The time that everybody stays at the table after the meal has finished is just as important as the food. 
They talk, tell stories and laugh together. At Christmas, La Rejunta is a giant version of a family meal.

For 70 years, UNICEF has been working on the ground in 190 countries and territories to promote children’s survival, protection and development. The world’s largest provider of vaccines for developing countries, UNICEF supports child health and nutrition, good water and sanitation, quality basic education for all boys and girls, and the protection of children from violence, exploitation, and AIDS. UNICEF is the driving force that helps build a world where the rights of every child are realized. As a global authority UNICEF is able to influence decision makers at the global level and turn the most innovative ideas into reality.

In all of its work, UNICEF takes a life-cycle based approach, recognizing the particular importance of early childhood development and adolescence. UNICEF programmes focus on the most disadvantaged children, including those living in fragile contexts, those with disabilities, those who are affected by rapid urbanization and those affected by environmental degradation.

UNICEF was created with a distinct purpose in mind: to work with others to overcome the obstacles that poverty, violence, disease and discrimination place in a child’s path. We advocate for measures to give children the best start in life, because proper care at the youngest age forms the strongest foundation for a person’s future.

We promote girls’ education – ensuring that they complete primary education as a minimum – because it benefits all children, both girls and boys. Girls who are educated grow up to become better thinkers, better citizens, and better parents to their own children. We act so that all children are immunized against common childhood diseases, and are well nourished: no child should suffer or die from a preventable illness. We work to prevent the spread of HIV/AIDS among young people because it is right to keep them from harm and enable them to protect others. We help children and families affected by HIV/AIDS to live their lives with dignity.

 UNICEF is the world’s largest provider of vaccines.

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: 
The Winterthur Museum is a collection and a house. There are many museums devoted to the decorative arts and many house museums, but rarely in the United States is a great collection displayed in a great country house. Passing through successive generations of a single family, Winterthur has been a private estate for more than a century. Even after the extensive renovations made to it between 1929 and 1931, the house remained a family residence. This fact is of importance to the atmosphere and effect of the museum. The impression of a lived-in house is apparent to the visitor: the rooms look as if they were vacated only a short while ago whether by the original owners of the furniture or the most recent residents of the house can be a matter of personal interpretation. Winterthur remains, then, a house in which a collection of furniture and architectural elements has been assembled. Like an English country house, it is an organic structure; the house, as well as the collection and manner of displaying it to the visitor, has changed over the years. The changes have coincided with developing concepts of the American arts, increased knowledge on the part of collectors and students, and a progression toward the achievement of a historical effect in period-room displays. The rooms at Winterthur have followed this current, yet still retained the character of a private house.
The concept of a period room as a display technique has developed gradually over the years in an effort to present works of art in a context that would show them to greater effect and would give them more meaning for the viewer. Comparable to the habitat group in a natural history museum, the period room represents the decorative arts in a lively and interesting manner and provides an opportunity to assemble objects related by style, date, or place of manufacture.

What happened at Winterthur between 1929 and 1931?

Although people drive in all countries, the rules can be quite different between nations and areas. For this reason, you should always learn the laws before you decide to drive in a foreign country. If you are not careful, you can get into trouble since the rules might be very different from what you are used to. For example, you can find some big differences in laws related to the minimum driving age, the appropriate side of the road to drive on, and mobile phone use while driving.
In the U.S., people who live in Alaska may obtain a learner’s permit (legal permission to drive while being supervised) at the age of fourteen. This is quite different from the driving laws of Niger, where a person must be at least twenty-three years old to drive. If you are inquisitive to know the minimum driving age in most countries, the answer is eighteen. It may also surprise you to learn that not every country allows its citizens to drive, although most of them do. For example, women are not allowed to drive in Saudi Arabia no matter how old they are. Instead, they must have a male family member or hired male driver to travel by car.
Driving on the right or left side of the road also varies. For instance, in Great Britain, Cyprus, Australia, India, and Malaysia people drive on the left. However, in the U.S., Mexico, France, and Canada people are required to drive on the right. As a matter of fact, one country can have different driving rules for different areas. People in Hong Kong drive on the left, while drivers in other parts of China use the right side of the road.
Other driving laws that are different between countries include those related to using mobile phones. In Japan, using any kind of mobile phone device is illegal, even if you do not need to hold the phone with your hands. However, in Argentina and Australia, drivers are allowed to talk on their mobile phones as long as they do not use their hands. 
You might also find it interesting to learn that some countries have very unusual laws. For example, in the country of Cyprus, it is against the law to eat or drink anything while driving. Even more interesting is that in Germany, there is a famous road called the Autobahn, where certain parts have no speed limit at all!

According to the passage, it is illegal to eat or drink while driving in_______.

HISTORY LESSONS
“History is the version of past events that people have decided to agree upon"
Naponeon Bonapart 
Think of three historical figures. What do you know about them? Where did you get your information from? The chances are that you either read it somewhere or someone who read it somewhere told you about it. Did you ever think about who wrote down these facts? How can you be sure that they are true? The thing is, many historical “truths” are historical myths. 
Let's take some examples. In America, 4th July is Independence Day, the most important day in the American Calendar, which Americans celebrate with parades and fireworks. It was on 4th July, 1776 that Congress approved the Declaration of Independence. It was a good start. However, the struggle continued for another seven years after this, with some of the most brutal fighting in the whole war, as King George III was not willing to grant America total Independence, which was the only arrangement that the American leaders would accept. So the fighting continued. The first draft on a Treaty of Peace was signed in November 1782 and in February 1783 the King officially announced that the war would soon be over. This led to the signing of the Treaty of Paris on 3rd September that same year. 
Think about the discovery of America. What's the first name that comes to mind? More than likely it's Christopher Colombus.Was America really discovered by him? He had set out to reach Asia and that's where he thought he was when he came to America. But there were many people there before him. The first ones were certainly the Native Americans, thousands years before 1492. Where had they come from? Even the Vikings had made a number of expeditions, with Leif Eriksson landing there in around 1000 A.D. Perhaps Amerigo Vespucci was the discover of America. After all, unlike Columbus before him, he was the first fifteen - century explorer to realise where has was, or rather, where he definitely wasn't. so, maybe the word “re-discover” is more accurate when it comes to Columbus, if history is to give him any credit at all. 
Everyone believes such historical "facts” because, like you, they got them from what they thought was a reliable source. But how can such things be written down in the first place? One of the reasons must be that history is seldom “cut - and - dried”. The events are often complicated and messy. The achieving of American independence was a lengthy affair. Presumably 4th July was chosen as the date to celebrate because it was seen as more significant than the date of the actual end of the war. Another reason is that such myths always contain a grain of truth. Columbus was not the first person to travel to America, but he was the first fifteenth-century explorer to go there. His “re-discovery” was, from a historical point of view, extremely significant for Europe since his voyages opened up large-scale commerce between Europe and America. 
History has traditionally been written by the winners. If the conquered indigenous peoples had written the history of the discovery of the New World, it would most probably have been very different, but not necessarily objective: the point of view of the conquered can be just as biased as the point of view of the conqueror. But that is not the whole story. The writing of history depends not only on the "side” the writer is on, but also on the culture and attitudes of the era it is written in. 
History is always subjective. So, remember: when you read history, take it with a pinch of salt.

   The American type of football was developed in the 19th century from soccer and rugby football. Played by professionals, amateurs, college and high school students, or young children, football in American is one of the most popular sports besides basketball and baseball. It attracts millions of fans each fall and people are very supportive of their favourite teams. The football playing field of today is rectangular in shape and measures 100 yards long and 53.5 yards wide. White lines are painted on the playing field to mark off the distances to the end zone. The games is divided into four quarters, each fifteen minutes long. The first two quarters are known as the first half. There is a rest period between two halves which usually last about fifteen minutes. Each team has eleven players. Each team has offensive players who play when the team has possession of the ball and defensive players who play when the other team has the possession of the ball. Because of the body contact players have during the game, helmets are worn to protect their head and face area, whereas pads are worn to protect the shoulders, arms, and legs. Also, there are officials carrying whistles and flags to make certain that the rules of the game are followed during the game. The football is made of leather and is brown in colour. It is shaped much like an oval and has white rings near each end of the football. These rings help the players see the ball when it is thrown or someone is running with it. The eight stitches on the top of the football help the players to grip the ball when throwing or passing. The most famous game of the year is Super Bowl that is played in January or February. It is televised around the world and is watched by millions of people each year.

AN UNWELCOME GUEST
Of the one in seven people in the UK who claim to have seen a ghost, the majority are women. This may be because women have far more association with the spirit world. Women trust their emotions and are generally better able than men to cope with the unexpected.
Housewife Fiona Blair describes herself as very practical and down-to-earth, and never believed in the idea that a house could be haunted. That all changed when she and her family moved into a manor house in the Midlands. Although the surveyor reckoned that the house required a lot of attention and was somewhat damp, they thought it was stunning. They could just afford it and it would be a good investment, so they took the plunge and decided to buy it.
Nonetheless, right from the start, Fiona had a strange sense that they were not alone in the house. One of her teenage daughters had left a towel over the back of a chair in the kitchen. Fiona was in the garden, and when she returned to the house, the towel was over the kitchen table like a tablecloth. On other occasions the family would find that objects such as glasses and vases had been turned upside-down.
This was only the start of the peculiar happenings. A particularly strange incident happened on Fiona's birthday. Fiona's husband, Mark, came home from work and went into the living room. He immediately came rushing out to ask who had bought her the beautiful flowers - but nobody had given Fiona flowers and her daughters had not put the flowers there. It remained a mystery how they had miraculously appeared.
Fiona was curious and decided to find out about the history of the house. What she discovered was rather alarming. Apparently a young girl, servant to a previous generation of owners, had been found dead in peculiar circumstances in the attic. Fiona and her family inevitably began to feel claustrophobic and trapped in the house, and eventually decided that they would have to move.
Unfortunately, things were not as simple as that. Each time they attempted to show the house to potential buyers, Fiona would of course ensure beforehand that everything was neat and tidy in order to make a good impression. But by the time anyone arrived, the entire house would be in a complete mess, and visitors complained of an unpleasant atmosphere. Eventually, after many months, an American couple viewed the house, and decided it had a certain attraction. For some reason, the ghost did not play its usual tricks, and Fiona was able to sell what had been her dream home.
Now living in a spacious modern apartment in London, Fiona wants to forget it all and move on with her life. 'At one point I thought I might be going out of my mind, it was all so frightening. We can almost laugh about it all now, but I hope we never experience anything like that again.

The biologist’s role in society as well as his moral and ethical responsibility in the discovery and development of new ideas has led to a reassessment of his social and scientific value systems. A scientist can no longer ignore the consequences of his discoveries; he is as concerned with the possible misuses of his findings as he is with the basic research in which he is involved. This emerging social and political role of the biologist and all other scientists requires a weighing of values that cannot be done with the accuracy or the objectivity of a laboratory balance. As a member of society, it is necessary for a biologist now to redefine his social obligations and his functions, particularly in the realm of making judgments about such ethical problems as man's control of his environment or his manipulation of genes to direct further evolutionary development.
As a result of recent discoveries concerning hereditary mechanisms, genetic engineering, by which human traits are made to order, may soon be a reality. As desirable as it may seem to be, such an accomplishment would entail many value judgments. Who would decide, for example, which traits should be selected for change? In cases of genetic deficiencies and disease, the desirability of the change is obvious, but the possibilities for social misuse are so numerous that they may far outweigh the benefits.
Probably the greatest biological problem of the future, as it is of the present, will be to find ways to curb environmental pollution without interfering with man's constant effort to improve the quality of his life.

According to the passage, a modem scientist should be more concerned about________.

It is difficult to write rules that tell exactly when we should apologize, but it is not difficult to learn how. If we have done something to hurt someone’s feeling or if we have been impolite or rude, we should apologize. An apology indicates that we realize we have made a mistake, and we are sorry for it. It is a way of expressing our regret for something. When we apologize, we admit our wrongdoing, usually offer a reason for it, and express regret.
The simplest way to apologize is to say “I’m sorry”, but often that is not enough. Let’s take a common situation. Mario is late for class and enters the classroom, interrupting the teacher in the middle of the class. What does he do? The most polite action is usually to take a seat as quietly as possible and apologize later. But if the teacher stops and waits for him to say something, he could apologize simply “I’m sorry I’m late”, ask permission to take his seat, and sit down. Naturally, more than this, a reason for the tardiness, is needed, but this is not the time or the place for it because he has already caused one interruption and doesn’t need to make it any longer or worse than it already is.

Which of the following is NOT mentioned in the passage as the most polite action in Mario’s case?

TRANSPORT IN THE CITY

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.

   In Science, a theory is a reasonable explanation of observed events that are related. A theory often involves an imaginary model that helps scientists picture the way an observed event could be produced. A good example of this is found in the kinetic molecular theory, in which gases are pictured as being made up of many small particles that are in constant motion.

   After a theory has been publicized, scientists design experiments to test the theory. If observations confirm the scientists’ predictions, the theory is supported. If observations do not confirm the predictions, the scientists must search further. There may be a fault in the experiment, or the theory may have to be revised or rejected.

   Science involves imagination and creative thinking as well as collecting information and performing experiments. Facts by themselves arc not science. As the mathematician Jules Henri Poincare said: "Science is built with facts just as a house is built with bricks, but a collection of facts cannot be called science any more than a pile of bricks can be called a house."

   Most scientists start an investigation by finding out what other scientists have learned about a particular problem. After known facts have been gathered, the scientist comes to the part of the investigation that requires considerable imagination. Possible solutions to the problem are formulated. These possible solutions are called hypotheses. In a way, any hypothesis is a leap into the unknown. It extends the scientist's thinking beyond the known facts. The scientist plans experiments, performs calculations, and makes observations to test hypotheses. For without hypotheses, further investigation lacks purpose and direction. When hypotheses are confirmed, they are incorporated into theories.

According to the second paragraph, a useful theory is one that helps scientists to _______.

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

The past fifty years or so have seen the gradual disappearance of animals from this earth, fishes from the sea, trees and plants from the land.
Many factors result in this unpleasant phenomenon. Among them, hunting is the main factor that endangers wildlife. Some people kill wildlife for sport. They take pleasure in collecting heads and hides. Yet others specialize in commercial hunting like killing whales.

Apart from this, the rapidly growing human population threatens wildlife on land, too. Towns expand and roads have to be built, so forests are burnt and trees are chopped down. It seems that man needs every inch of land within his reach, so he moves on to the natural habitat of wildlife. Tigers, lions and leopards slowly die off without the food and shelter that the forests provide.

In addition, rapid urbanization means industrial expansion. Very often, poisonous chemicals, industrial wastes and oil are dumped into the rivers and seas. Fish and birds are threatened.

Many depend greatly on animals for survival. He needs their flesh, hides and furs. Thus, man cannot do without wildlife; or he himself would become extinct. The public should be made aware that it would be better to shoot the animals with a camera than with a gun. In this way, they can preserve and help wildlife to continue living rather than to move all signs of it.
 
Man must learn to farm the sea as he does the land. He should regulate the amount of frequency of his catch. He should allow fish to breed and multiply before netting them. A man also needs to build forest reserves, and to pass a law prohibiting the killing of animals, especially those that already rare. To retain the present animal kingdom, the least that man can do is to clean the seas and rivers to prevent pollution. The cycle of nature is such that it forms a vicious circle. The insecticides and pesticides that we spray on crops can kill the birds and animals that feed on them. When a man eats these poisoned animals, he himself can die. We must therefore test the chemicals to be used before they are sprayed or it might mean the death of man!

The growing human population threatens wildlife because ___________.

The World Trade Organization came into being in 1995. One of the youngest of the international organizations, the WTO is the successor to the General Agreement on Tariffs and Trade (GATT) established in the wake of the Second World War. So while the WTO is relatively young, the multilateral trading system that was originally set up under the GATT is over 70 years old. 
The past 70 years have seen an exceptional growth in world trade. Merchandise exports have grown on average by 6% annually. This growth in trade has been a powerful engine for overall economic expansion and on average trade has grown by 1.5 times more than the global economy each year. Total exports in 2016 were 250 times the level of 1948. The GATT and the WTO have helped to create a strong and prosperous trading system contributing to unprecedented growth.
The system was developed through a series of trade negotiations, or rounds, held under the GATT. The first rounds dealt mainly with tariff reductions but later negotiations included other areas such as anti-dumping and non-tariff measures. The 1986-94 round – the Uruguay Round – led to the WTO’s creation.
