Globally we use more energy than ever before, and the demand is rapidly growing. Economic expansion of emerging market economies, population growth and our increasing use of energy-consuming devices are among the most important contributing factors. About one-third of the radiation hitting Earth’s atmosphere is reflected back out into space by clouds, ice, snow, sand and other reflective surfaces. The other two-thirds is absorbed by the Earth’s surface and the atmosphere. As the land, oceans and atmosphere heat up, they re-emit energy as infrared thermal radiation, which passes through the atmosphere. Heat-trapping gases like carbon dioxide (CO2) absorb this infrared radiation and prevent it from dissipating into space, giving rise to what we know as the greenhouse effect. The accumulation of CO2 and other greenhouse gases in the atmosphere is the dominating driver of recent climate change. CO2 is estimated to be responsible for 64 % of man-made global warming. Other greenhouse gases are released in much smaller amounts but still contribute significantly to the overall warming effect, as they are much more potent heat-trapping gases than CO2. The EU is taking action on many levels. One example is on fluorinated gases that are contributing less than CO2 but still a particular point of concern in addressing climate change. They are used in several types of products, such as in refrigeration, air-conditioning and heat pump equipment. While fluorinated gases are released into the atmosphere in smaller quantities than other greenhouse gases, they are extremely potent – they produce a warming effect 23 000 times greater than CO2. For this reason the EU has decided to control their use. The EU’s regulation on fluorinated greenhouse gases aims at cutting the Union’s emissions by two-thirds compared to 2014 levels. Chemicals are not only part of the problem – they are also part of the solution. Sustainable energy sources like solar power rely on chemical innovation using, for example, nanomaterials. One of the main challenges with renewable energy is how to increase its viability with the help of energy storage solutions. For example, solar panels have the best conditions in the desert, but that is not where most people live. Windmills also produce power during the night, which is when our energy consumption is at its lowest. In other words, technologies to improve energy storage and transportation is one of the important areas of research where innovation is needed

Read the following passage and choose the best answer (A, B, C, D):
In 1988, a year before the Soviet Union collapsed, the 13th National Congress of the  Communist Party of Vietnam adopted a resolution to have “more friends and fewer enemies”. So it was not surprising when Vietnam expressed interest in joining ASEAN as early as 1992, or when it did in fact join in July 1995.   Vietnam’s membership of the grouping integrated its security with the whole of Southeast Asia and created a favourable environment for economic development. This, in turn, raised Vietnam’s global image, leading to increased cooperation with multiple players in the region and greater bargaining clout with super powers like the United States and China. As an ASEAN member, Vietnam has worked hard to secure peace and reconciliation among Southeast Asian nations, which were once deeply divided by war. Vietnam was the first Indochinese country to join ASEAN, and its move helped end confrontation between the Indochinese bloc and ASEAN. Vietnam has also helped ASEAN partner with non-regional players.  Vietnam also led efforts within ASEAN to ensure regional security. Soon after becoming a member, Vietnam signed the Treaty on the Southeast Asian Nuclear-WeaponFree Zone and was one of the founding members of the ASEAN Regional Forum. But the most proactive steps by Hanoi towards regional stability have revolved around disputes in the South China Sea. A direct claimant in the dispute, Vietnam, along with the Philippines, has made constant efforts to put the South China Sea on ASEAN’s agenda, ensuring conflict is dealt with in a constructive way. Vietnam has shown constant support for the Declaration on the Conduct of Parties in the South China Sea, ASEAN’s Six-Point Principles on the East Sea, and the soon-to-be-concluded Code of Conduct of Parties in the East Sea. Vietnam calls for the settlement of disputes by peaceful means on the basis of international law and the 1982 United Nations Convention on the Law of the Sea — including through regulations on respecting exclusive economic zones and the continental shelf of coastal countries. Vietnam has remained committed to ASEAN since it joined in 1995 and Vietnam is beginning to integrate further with the global community, and  cooperation with ASEAN will always be an important pillar in its foreign policy. But Vietnam’s interest in ASEAN is not
limited to security issues. Its leadership also drives efforts toward an ASEAN Economic Community (AEC).

Read the following passage and choose the best answer (A, B, C, D):
Paul Watson is an environmental activist. He is a man who believes that he must do something, not just talk about doing something. Paul believes in protecting endangered animals, and he protects them in controversial ways. Some people think that Watson is a hero and admire him very much. Other people think that he is a criminal. On July 16th, 1979, Paul Watson and his crew were on his ship, which is called the Sea Shepherd. Watson and the people who work on the Sea Shepherd were hunting on the Atlantic Ocean near Portugal. However, they had a strange prey, instead of hunting for animals, their prey was a ship, the Sierra. The Sea Shepherd found the Sierra, ran into it and sank it. As a result, the Sierra never returned to the sea. The Sea Shepherd, on the other hand, returned to its home in Canada. Paul Watson and his worked thought that they had been successful. The Sierra had been a whaling ship, which had operated illegally. The captain and the crew of the Sierra did not obey any of the international laws that restrict whaling. Instead, they killed as many whales as they could, quickly cut off the meat, and froze it. Later, they sold the whale meat in countries where it is eaten. Paul Watson tried to persuade the international whaling commission to stop the Sierra. However, the commission did very little, and Paul became impatient. He decided to stop the Sierra and whaling ships in any way that he could. He offered to pay $25,000 to an one who sank any illegal whaling ship, and he sank the Sierra. He acted because he believed that the whales must be protected. Still, he acted without the approval of the government; therefore, his action controversial. Paul Watson is not the only environmental activist. Other men and women are also fighting to protect the Earth. Like Paul Watson, they do not always have the approval of their governments, and like Watson, they have become impatient. Yet, because of their concern for the environment, they will act to protect it.

Read the following passage and choose the best answer (A, B, C, D):
Certain birds are, more often than not, considered bad luck, or even a sign of impending death. For example, all over the world, both crows and ravens have some connection to war, and death. In early times, crows and ravens were thought to accompany the gods of war, or be signs of the gods’ approaching arrival. This idea later changed. Crows in particular were thought to be harbingers of ill fortune or, in some cases, guides to the afterlife. Woe be it to the person who saw a single crow or raven flying overhead, for this was most certainly a portent of death in the near future. Interestingly, though potentially bad luck for people individually, the raven is considered to be good luck for the crown of England. So much so, in fact, that a “raven master” is, even today, an actual government position in London. He takes care of the ravens there and also clips their wings, ensuring that these birds can never fly far from the seat of the British government. This way, the kingdom will never fall to ill fortune. Another bird that is thought to play a part in forecasting the fortunes of people is the swallow. Depending on how and when it is seen, the swallow can be a harbinger of either good or ill fortune. Perhaps inspired by the swallow’s red-brown breast, Christian people initially related the swallow to the death of Jesus Christ. Thus, people who saw a swallow fly through their house considered it a portent of death. Later, however, farmers began to consider swallows signs of good fortune. Any barn that has swallows living in it is sure to be blessed in the following year. Farmers also have to beware of killing a swallow; that would be certain to end any good luck they might have had. Though many people think these superstitions are old wives’ tales, there is actually some evidence to support them. For example, crows and ravens, being scavengers, appear at the aftermath of battles. Thus, large numbers of crows and ravens could be good indications of war in an area. As well, swallows feed on insects that can cause infections in cattle. Thus, a farmer who has many swallows in his barn may actually have healthier animals on his farm. Therefore, the next time you feel inclined to laugh at an old wives’ tale, maybe you had better find out if there is any truth to it first!
8. Which of the following most accurately reflects the author’s suggestion in the last paragraph?

Read the following passage and choose the best answer (A, B, C, D):
Many of us experience multiple queues on an average day. If the move quickly,  they’re soon forgotten. But a slow line can be extremely annoying. What separated a good queuing experience from a bad one, however, is not just the speed of the line. In fact, how the wait makes us feel can have a greater impact on our perception of a queues than how much time we spend in it.  To understand how, consider the story of an airport getting complaints for the long waits at the baggage carousel. After trying fruitlessly to make baggage delivery faster, the airport simple moved the arrival gates outside of the main terminal, making people walk six times longer. Time was spent walking instead of waiting around and complaints dropped to almost zero as a result. A similar example can be observed during the postwar boom in high rise buildings in many elevator halls, where mirrors are installed to give people a chance to adjust their clothes and make sure that they look great, which distracts them from the long wait for their elevator.
For many people, the golden standard of line design and management can be found in theme parks, where waiting lines are such as integral part that companies are not afraid to invest. Some of the tricks theme parks use to make waits more bearable are hiding the line behind corners or walls to make it appear shorter and inflating the waiting times announced at each attraction. If the sign says the wait is an hour, often it will actually be more like 45 minutes, which will make people feel like they’re 15 minutes ahead of schedule. At Disneyland, designers and engineers also add games and other activities in order to give guests plenty to do, which keeps them from measuring the passage of time. According to Larson, Disney lines are so entertaining that on rainy days, when attendance is low, rides in the parks may fill up too slowly because families linger in the queue for too long.  Clever line design can also be found in supermarkets. Multiple parallel lines, each in front of a checkout, can be great if you’re in a fast one, but can feel very unfair if you’re stuck in a slow one. That’s why businesses are increasingly switching to the serpentine line, in which all customers are funneled into a single queue and then sent to the first available checkout. Compared to parallel lines, the serpentine triumphs in the key department of fairness: it’s strictly first come, first served, so no one arriving after you can be served before you
3. What can be inferred from the passage?

Read the following passage and choose the best answer (A, B, C, D):
Christmas is around the corner, which means it’s about time you examined carefully your holiday gift list. “Choosing the wrong gift can be kind of risky for relationships because it implies that you and the receiver don’t have anything in common,” says Elizabeth Dunn, a psychology professor at the University of British Columbia in Canada. Her research has also showed that undesirable gifts can sometimes negatively impact the receiver’s perception of a relationship’s future potential. Since you don’t want your holiday gift to cause more harm than good, how can you be sure to choose a gift the receiver will love? Psychology may have the answer. Contrary to common belief, studies have actually shown that spending more does not always guarantee a well-received gift. “It seems quite self-evident to most of us that if you spend more, you’re going to get a better girl. But as it turns out, there’s no evidence that recipients associate the cost of a gift with how much they enjoy that gift,” says Jeff Galak, an associate professor of marketing at the Carnegie Mellon Tepper School of Business in the US city of Pittsburgh. Galak acknowledges that your gift may have to hit a certain price due to tradition or expectations. “But once you meet that cost, it doesn’t matter at all if you buy something even more valuable than that limit,” he says. Galak says the trick for giving a great and unforgettable gift is to think past the moment of handing it over. “When most givers give gifts, they try to make the moment they give the gift perfect and want to see the smile on recipient’s face right in that moment,” says Galak. “But in reality, what most recipients really love about a gift is how much value they’re going to derive from it over an extended time period.” In other words, it might be exciting to watch a friend open a gift of a concert ticket, but since it’s a gift that cannot be enjoyed over time, it may soon be forgotten. It is also suggested that if you can’t think of a good gift, just ask the recipient what they want. “People want to be creative and surprise the recipient,” says Dunn. “but the better gift will be whatever it is they say they like.” At the end of the day, don’t fret too much about giving a terrible gift. Unless something is wildly inappropriate, the recipient will fell some level of appreciation. Galak says that over the course of his research he has asked thousands of participants about gifts they have received, and he rarely hears someone talk about a bad girl. And even if you do give a sub-standard gift to someone you are close to you may be saved by your thoughtfulness. “When someone does something puzzling that needs to be explained – like give a bad gift – that’s when you think about what’s on the other person’s mind,” says Nicholas Epley, a professor at the University of Chicago Booth School of Business. His research shows that if your recipient feels like you at least spent a lot of time making your selection, they’ll appreciate the effort that went into choosing a less desirable gift. In other words, the old saying ‘it’s the thought that counts’ really might be true.  
6. In paragraph 3, Jeff Galak said that what recipients actually like about a gift is ________

Most people think that lions only come from Africa. This is understandable because in fact most lions do come from there but this has not always been the case. If we went back ten thousand years, we would find that there were lions roaming vast sections of the globe. However now, unfortunately only a very small section of the lion's former habitat remains.
Asiatic lions are sub-species of African lions. It is almost a hundred thousand years since the Asiatic lions split off and developed as a sub-species. At one time the Asiatic lion was living as far west as Greece and they were found from there, but in a band that spreads east through various countries of the Middle East, all the way to India. In museums now, you can see Greek coins that

have clear images of the Asiatic lion on them. Most of them are dated at around 500 B.C. However, Europe saw its last Asiatic lions roaming free two thousand years ago. Over the next nineteen hundred years the numbers of Asiatic lions in the other areas declined steadily, but it was only in the nineteenth century that they disappeared from everywhere but in India.
The Gir Wildlife Sanctuary in India was established especially to protect the Asiatic lion. There are now around three hundred Asiatic lions in India and almost all of them are in this sanctuary. However, despite living in a sanctuary, which makes them safe from hunters, they still face a number of problems that threaten their survival. One of these is the ever-present danger of disease. This is what killed more than a third of Africa’s Serengeti lions in 1994, and people are fearful that something similar could happen in the Gir Sanctuary and kill off many of the Asiatic lions there.
India's lions are particular vulnerable because they have a limited gene pool. The reason for this is interesting is because all of them are descended from a few dozen lions that were saved by a prince who took a particular interest in them. He was very healthy, and he managed to protect them; otherwise they would probably have died out completely.
When you see the Asiatic lion in India, what you sense is enormous vitality. They are very impressive animals and you would never guess that they have this vulnerability when you look at them.

According to the passage, nowadays we can find the Asiatic lion .

For hundreds of years, giving flowers have been a social means of communication. In the United States, flowers are often given during rites of passage, for commemorating special occasions or as a heartfelt gift between loved ones and friends. Flower gifting also occurs in most countries around the world. However, the meanings and traditions often vary. While students traditionally gave their favorite teacher an apple in past years, in China, teachers are given flowers. Peonies are by far the flower most often given in China. They are also quite popularly used for weddings. Strangely, potted plants are not considered a pleasant gift among Asian cultures. The people believe that like a plant confined by a pot, the gift symbolizes a binding or restriction. In Russia, in lieu of giving birthday presents, the guest of honor receives a single flower or an unwrapped bouquet. Floral arrangements or baskets are not given. Russians celebrate a holiday known as Woman’s Day. Traditional gifts include red roses, hyacinths or tulips. When there is a funeral or other occasion where someone wishes to express sympathy, carnations, lilies or roses are given in circular configurations, which signify the transition of birth, life and death to rebirth. In this instance, the color of choice is commonly yellow. For joyous occasions, arrangements and bouquets generally contain an odd number of flowers In the times of ancient Rome, brides carried flowers to scare away evil spirits and encourage fertility. The Dutch believed that flowers were food for the soul. When invited to someone’s home in Great Britain, it is tradition to bring a gift of flowers. All types are acceptable except white lilies, which are usually seen at funerals. Not unlike the United States, red roses are a symbol of love. Flowers are generally gifted in odd numbered increments regardless of the occasion. However, the Brits also have superstitions regarding the number 13, so the number is avoided. In the southern region of the continent, flowers are traditionally given during Christmas. Egyptians are much more conservative and restrict flower gifting to funerals and weddings. While certain flowers may have significant meanings for some, flowers in Las Vegas and across the United States flowers are an accepted gift for any reason desired.

Human beings are plagued by all kinds of diseases and millions of people die from them. Many of these diseases such as diabetes, polio, whooping cough and diphtheria can be fatal and in the past, people used to die from them. However, with modern technology and a lot of research, scientists and doctors have come up with various ways to cure these diseases, and consequently, many lives are saved. In doing the medical research, doctors have come face to face with many problems. One such problem is the opposition that comes from animal activists. They are against the inhuman treatment of animals. They argue that in conducting their medical research, doctors put animals through a very painful process and this should be stopped. According to the fiercest animal activists, nothing justifies the use of animals in medical experiments, even if lives might be saved. To get their message across, animal activists are even willing to resort to the use of violence. Many animal protection groups, like the Animal Liberation Front (ALF), have broken into laboratories illegally to ‘rescue’ animals. They take away whatever animals they can find and free them. These people also make their case by threatening the researchers. They vandalize medical equipment, and in the most serious cases, they even . In stealing the animals, the activists are actually hindering the progress of medicine. In many cases, the animals were part of research for the cure for various diseases and visual defects in babies. Cures for problems that people face, therefore, come slower and in the waiting period, more people die. Researchers have come up with many cures in the process of working with animals and on animals. Organ transplants are so common today, but we forget that they became only  possible after they were tested on animals. Doctors were able to come up with a cure for river blindness, a disease that affects millions of people in South America and Africa. These are only a few examples, and there are many more. In spite of what animal activists think, most researchers do not treat animals cruelly. In fact, mistreated animals which are in agony will affect the quality of research so that results obtained are not really reliable. Thus, researchers do try to treat animals as well as possible. In the long run, animal activists can cause serious damage to the future of medicine. With their persistent campaigning, much of the public supports their cause. People with AIDS or cancer need doctors to do research to save their lives, and often it is a case where animal research is crucial before any cure can be found

Read the following passage and choose the best answer (A, B, C, D):
After World War II drew to a close in the mid-20th century, a new conflict began.  Known as the Cold War, this battle pitted the world’s two great powers–the democratic, capitalist United States and the communist Soviet Union–against each other. By the mid1950s, the U.S.-Soviet Cold War had worked its way into the fabric of everyday life in both countries, fueled by the arms race and the growing threat of nuclear weapons, wide-ranging espionage and counter-espionage between the two countries, war in Korea and a clash of words and ideas carried out in the media. These tensions would continue throughout the space race, exacerbated by such events as the construction of the Berlin Wall in 1961, the Cuban missile crisis of 1962 and the outbreak of war in Southeast Asia. Space exploration served as another dramatic arena for Cold War competition. On October 4, 1957, a Soviet R-7 intercontinental ballistic missile launched Sputnik (Russian for “traveler”), the world’s first artificial satellite and the first man-made object to be placed into the Earth’s orbit. Sputnik’s launch came as a surprise, and not a pleasant one, to most Americans. In the United States, space was seen as the next frontier, a logical extension of the grand American tradition of exploration, and it was crucial not to lose too much ground to the Soviets. In addition, this demonstration of the overwhelming power of the R-7 missile– seemingly capable of delivering a nuclear warhead into U.S. air space–made gathering intelligence about Soviet military activities particularly urgent.  Beginning in the late 1950s, space would become another platform for the competition, as each side sought to prove the superiority of its technology, its military firepower and–by extension–its political-economic system.
4. According to paragraph 2, why did most Americans harbour an unanimous displease toward Soviet’s achievement?

Plastic bags are used by everybody. From a vegetable vendor to a designer store, everyone seems to use them. Even though they are one of the modern conveniences that we seem to be unable to do without, they are responsible for causing pollution, killing wildlife, and using up the precious resources of the Earth. But, most of us are blissfully unaware of the repercussions that are occurring and will take place in the future because of the plastic bags. Every once in a while, the government passes out an order banning store owners from providing plastic bags to customers for carrying their purchases, with little lasting effect. Plastic bags are very popular with both retailers as well as consumers because they are cheap, strong, lightweight, functional, as well as a hygienic means of carrying food as well as other goods. About a hundred billion plastic bags are used every year in the U.S. alone. And then, when one considers the huge economies and populations of India, China, Europe, and other parts of the world, the numbers can be staggering. The problem is further exacerbated by the developed countries shipping off their plastic waste to developing countries like India. Once they are used, most bags go into landfills. Each year, more and more bags are ending up littering the environment. Once they become litter, plastic bags find their way into our waterways, parks, beaches, and streets. And, if they are burned, they infuse the air with toxic fumes. About 100,000 animals, such as dolphins, turtles, whales, penguins are killed every year due to these bags. Many animals ingest plastic bags, mistaking them for food, and therefore, die. And worse, the ingested plastic bag remains intact even after the death and decomposition of the animal. Thus, it lies around in the landscape where another victim may ingest it. One of the worst environmental effects is that they are non-biodegradable. The decomposition takes about 400 years. No one will live so long to witness the decomposition of plastic! Thus, save the environment for the future generations as well as animals. Petroleum products are diminishing and getting more expensive by the day, since we have used this non-renewable resource increasingly. And to make plastic, about 60-100 million barrels of oil are needed every year around the world. Surely, this precious resource should not be wasted on producing plastic bags, should it? Petroleum is vital for our modern way of life. It is necessary for our energy requirements - for our factories, transportation, heating, lighting, and so on. Without viable alternative sources of energy yet on the horizon, if the supply of petroleum were to be turned off, it would lead to practically the entire world grinding to a halt. So, what can be done? A tote bag can make a good substitute for carrying groceries and the shopping. You can keep the bag with the cashier, and then put your purchases into it instead of the usual plastic bag. Recycling the bags you already have is another good idea. These can come into use for various purposes, like holding your garbage, instead of purchasing new ones. While governments may be working out ways to lessen the impact of plastic bags on the environment; however, each of us should shoulder some of the responsibility for this problem, which ultimately harms us. Plastics are not only nonbiodegradable, but are one of the major pollutants of the sea. For a clean and green environment, try to use alternatives to plastic whenever and wherever possible. Cut down your use of plastic, and do your bit to save our planet

The Moon is our close cosmic neighbor, and humans have been exploring its surface ever since they first developed telescopes. The first lunar exploration vehicles of the 1950s were primitive pioneers. But aerospace technology developed so rapidly that only about a decade separated the first flyby forays and Neil Armstrong’s history-making steps on the Moon’s surface. In January 1959, a small Soviet sphere bristling with antennas, dubbed Luna 1, flew by the Moon at a distance of some 3,725 miles (5,995 kilometers). Though Luna 1 did not impact the Moon’s surface, as was likely intended, its suite of scientific equipment revealed for the first time that the Moon had no magnetic field. The craft also returned evidence of space phenomena, such as the steady flow of ionized plasma now known as solar wind. Later in 1959, Luna 2 became the first spacecraft to land on the Moon’s surface when it impacted near the Aristides, Archimedes, and Autolycus craters. A third Luna mission subsequently captured the first blurry images of the far–or dark–side of the Moon. In 1962 NASA placed its first spacecraft on the Moon—Ranger 4. The Ranger missions were kamikaze missions; the spacecraft were engineered to streak straight toward the Moon and capture as many images as possible before crashing onto its surface. Unfortunately, Ranger 4 was unable to return any scientific data before slamming into the far side of the Moon. Two years later, however, Ranger 7 streaked toward the Moon with cameras blazing and captured more than 4,000 photos in the 17 minutes before it smashed onto the surface. Images from all the Ranger missions, particularly Ranger 9, showed that the Moon’s surface was rough. They spotlighted the challenges of finding a smooth landing site on its surface. In 1966 the Soviet spacecraft Luna 9 overcame the Moon’s topographic hurdles and became the first vehicle to soft-land safely on the surface. The small craft was stocked with scientific and communications equipment and photographed a ground level lunar panorama. Luna 10 launched later that year and became the first spacecraft to successfully orbit the  Moon. The Surveyor space probes (1966-68) were the first NASA craft to perform controlled landings on the Moon’s surface. Surveyor carried cameras to explore the Moon’s surface terrain, as well as soil samplers that analyzed the nature of lunar rock and dirt. In 1966 and 1967 NASA launched lunar orbiters that were designed to circle the Moon and chart its surface in preparation for future manned landings. In total, five lunar orbiter missions photographed about 99 percent of the Moon’s surface. On July 20, 1969, Neil Armstrong and Edwin “Buzz” Aldrin became the first people to reach the Moon when their Apollo 11 lunar lander touched down in the Sea of Tranquility. Later missions carried a lunar rover that was driven across the satellite’s surface, and saw astronauts spend as long as three days on the Moon. Before the Apollo project ended in 1972, five other missions and a dozen men had visited the Moon. After the dramatic successes of the 1960s and 1970s, the major space programs turned their attention elsewhere for a period of several decades.

Read the following passage and choose the best answer (A, B, C, D):
Pick any day in the Piazza del Duomo in the Italian city of Pisa, and you will  undoubtedly spot a bunch of tourists posing for the same photo: hands outstretched towards the cathedral’s conspicuously tilting bell tower, as if they are supporting it with their sheer strength. The so-called Leaning Tower of Pisa is one of the most famous buildings in the world, although maybe not for the reasons its original architects would have wanted.  In 1173, construction began on a white marble bell tower for the cathedral complex in Pisa, located between the Arno and Serchio rivers in Tuscany, central Italy. By the time builders had finished the third of eight planned stories about five years later, the tower’s foundation had begun to settle unevenly on the ground beneath it, a dense mixture of clay, sand and shells. As a result, the structure had begun to tilt visibly toward the south. Shortly after that, war broke out between Pisa and Genoa, another Italian city-state, halting construction for nearly a century. This delay allowed the foundation to settle further, likely prevented the bell tower’s premature collapse.  When construction resumed, chief engineer Giovanni di Simone tried to compensate for the lean by adding extra masonry to the short side, but the additional weight caused the structure to tilt even further. The tower was officially completed around 1370, but its lean only increased over the next six centuries, becoming an integral part of the monument’s quirky appeal. Despite various attempts to reinforce it, Pisa’s tower continued to subside at a rate of some 0.05 inches per year, placing it in increasing danger of collapse. By 1990, it was leaning 5.5 degrees (or some 15 feet) from the perpendicular–the most extreme angle yet. That year, the monument was closed to visitors and the bells removed as engineers started extensive reparations to stabilize it. By siphoning earth from beneath and adding counterweights to the tower’s north end, they were able to reduce the lean to 13.5 feet, or 4.0 degrees from perpendicular. The straightening continued after the tower reopened in 2001, and in 2008 sensors showed the subsiding motion had stopped, after a total improvement of some 19 inches. Engineers now believe the Leaning Tower of Pisa will remain stable for some 200 years, barring an earthquake or other unpredictable disaster.
