When living and working in another country, there are numerous things to consider apart from the more obvious ones of climate, language, religion, currency, etc. Some important considerations are less obvious. For example, do you have a pet or do you enjoy a hobby such as horse riding? Your animal or hobby may be perceived in a completely different light in another culture so it’s important to consider the significance given to specific animals in different parts of the world and general perceptions towards them.
One example which is often mentioned in popular press is the case of dogs. In some cultures, like the US or UK, dogs are loved and considered a great pet to have at home and with the family. In other cultures, such as those where Islam is the majority religion, dogs may be perceived as dirty or dangerous. Muslims treatment of dogs is still a matter of debate amongst Islamic scholars. While these animals are widely considered by many Western cultures to be „man’s best friend’, the Koran describes them as “unhygienic”. Muslims will therefore avoid touching a dog unless he can wash his hands immediately afterwards, and they will almost never keep a dog in their home.
In Iran, for instance, a cleric once denounced „the moral depravity’ of dog owners and even demanded their arrest. If you are an international assignee living and working in Saudi Arabia or another Arabic country, you should remember this when inviting Arab counterparts to your house in case you have a dog as a pet. This is just one example of how Islam and other cultural beliefs can impact on  aspects of everyday life that someone else may not even question. A Middle Eastern man might be very surprised when going to Japan, for instance, and seeing dogs being dressed and pampered like humans and carried around in baby prams!
Dogs are not the only animals which are perceived quite differently from one culture to another. In India, for example, cows are sacred and are treated with the utmost respect. Conversely in Argentina, beef is a symbol of national pride because of its tradition and the high quality of its cuts. An Indian working in Argentina who has not done his research or participated in a cross cultural training programme such as Doing Business in Argentina may be surprised at his first welcome dinner with his Argentinean counterparts where a main dish of beef would be served.
It is therefore crucial to be aware of the specific values assigned to objects or animals in different cultures to avoid faux–pas or cultural misunderstandings, particularly when living and working in another culture. Learning how people value animals and other symbols around the world is one of the numerous cultural examples discussed in Communicaid’s intercultural training courses. Understanding how your international colleagues may perceive certain animals can help you ensure you aren’t insensitive and it may even provide you with a good topic for conversation.

After twenty years of growing student enrollments and economic prosperity, business schools in the United States have started to face harder times. Only Harvard’s MBA School has shown a substantial increase in enrollment in recent years. Both Princeton and Stanford have seen decreases in their enrollments. Since 1990, the number of people receiving Masters in Business Administration (MBA) degrees, has dropped about 3 percent to 75,000, and the trend of lower enrollment rates is expected to continue.
There are two factors causing this decrease in students seeking an MBA degree. The first one is that many graduates of four-year colleges are finding that an MBA degree does not guarantee a plush job on Wall Street, or in other financial districts of major American cities. Many of the entry- level management jobs are going to students graduating with Master of Arts degrees in English and the humanities as well as those holding MBA degrees. Students have asked the question, “Is an MBA degree really what I need to be best prepared for getting a good job?” The second major factor has been the cutting of American payrolls and the lower number of entry-level jobs being offered. Business needs are changing, and MBA schools are struggling to meet the new demands.

As used in the second paragraph, the word “struggling” is closest in meaning to

U.N. diplomats abandoned efforts to draft a treaty that would outlaw human cloning. They will likely settle for a weaker statement, and won’t seek a widespread ban, officials said. The debate began when Italy introduced a document into the UN. to stop any attempt at cloning human life. The Belgians objected to the use of the term “human life” in the document, because they feared it would put a stop to all forms of human cloning.
[1] There is near universal support among the United Nations’ 191 members for a ban on reproductive cloning-creating cloned babies. [2] Many countries have wrestled over whether to allow cloning for stem cell and other types of research. [3] Indeed, many researchers believe that stem cells could be used to repair nerve tissue or cure diseases, including Alzheimer’s. [4] Stem cells are taken from embryos and cloned, but extracting these cells kills the embryo. Opponents say that this is equal to murder.

Christina and James met in college and have been dating for more than five years. For the  past two years, they have been living together in a  condo  they  purchased jointly. While Christina and James were confident in their decision to enter into a commitment like a  20-year mortgage,  they are unsure if they want to enter into marriage. The couple had many discussions about marriage and decided that it just did not seem necessary. Wasn't it only a piece of  paper? And  didn't half of all marriages end in divorce?
Neither Christina nor James had seen much success with marriage while growing up. Christina was raised by a single mother. Her parents never married, and her father has had little contact with the family since she was a toddler, Christina and her mother lived with her maternal grandmother, who often served as a surrogate parent. James grew up in  a  two-parent household  until age seven, when his parents divorced. He lived with his mother for a  few years, and then    later with his mother and her boyfriend until he left for college. James remained close with his  father who remarried and had a baby with his new wife.
Recently, Christina and James have been thinking about having children and the subject of marriage has resurfaced. Christina likes the idea of her children growing up in a traditional  family; while James is concerned about possible marital problems down the road and negative consequences for the children should that occur. When they shared these concerns with their parents, James's mom was adamant that the couple should get married. Despite having been divorced and having a live-in boyfriend of 15  years, she believes that children are better off when  their parents are married. Christina's mom believes that the couple should do whatever they want but adds that it would "be nice" if they wed. Christina and James's friends told them, married or not married; they would still be a family.

What is the advice of the couple's parents?

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:
Generally, in order to be preserved in the fossil record, organisms must possess hard body parts such as shells or bones. Soft, fleshy structures are quickly destroyed by predators or decayed by bacteria. Even hard parts left on the surface for any length of time will be destroyed, therefore, organisms must be buried rapidly to escape destruction by the elements and to be protected against agents of weathering and erosion. Marine organisms thus are better candidates for fossilization than those living on the land because the ocean is typical the site of sedimentation, whereas the land is largely the site of erosion. The beds of ancient lakes were also excellent sites for rapid burial of skeletal remains of freshwater organisms and skeletons of other animals, including those of early humans, Ancient swaps were  particularly plentiful with prolific growths of vegetation, which fossilized in abundance. Many animals became trapped in bogs overgrown by vegetation. The environment of the swaps kept bacterial decay to a minimum, which greatly aided in the preservation of plants and animals. The rapidly accumulating sediments in flood plains, deltas, and stream channels buried freshwater organisms, along with other plants and animals that happened to fall into the water.
Only a small traction of all the organisms that have ever lived are preserved as fossils. Normally, the remains of a plant or animal are completely destroyed through predation and decay. Although it seems that fossilization is common for some organisms, for others it is almost impossible. For the most part of, the remains of organisms are recycled in the earth, which is fortunate because otherwise soil and water would soon became depleted of essential nutrients. Also, most of the fossils exposed on Earth’s surface are destroyed by weathering processes. This make for an incomplete fossil record with poor or no representation of certain species. The best fossils are those composed of that form the vast majority of unaltered fossils. Calcite and aragonite also contributed to a substantial number of fossils of certain organisms.

Life expectancy is the period of time that a person can expect to live. Life expectancy varies greatly between genders and cultures. It used to be that women had a lower life expectancy than men (1 in every 4 women died in childbirth), but now they live an average of four to five years longer than men. Life expectancy has been increasing rapidly over the last centuries. With the advent of such modern miracles as sewers, medicine and a greater understanding of how diseases are spread, our life expectancy has increased by 25-30 years.
In developing countries like Swaziland, where there is a high HIV/ AIDS rate, life expectancy is as low as 32.6 years. In developed countries like Australia, life expectancy rates are as high as 81 years. There are an increasing number of factors which can cancel out the disadvantages you have. The one that we are looking at now is how your career can affect your life expectancy. Choosing the wrong career can result in a shorter life!
If you want your career to positively influence your life expectancy, you have to be made of money. That's right. Rich people in wealthy areas of England and France live 10 years longer than the people in poorer areas. Having a successful career has its drawbacks, too if the result of hard work is stress.
Stress can lead to a number of psychological disorders such as depression, anxiety, fatigue, tension and aggression. These conditions may result in a lack of concentration and an increase in serious injuries at work. They can also lead to high blood pressure and heart attacks which seriously affect life expectancy.
If you are worried that your job might decrease your life expectancy, you probably need to avoid careers on "dangerous jobs" list such as timber cutters, pilots, construction workers, roofer, truck drivers.
So if you don't want to kick the bucket at an early age, choose a career in something other than timber cutting, but above all, remember to relax.

In the early 1800s, to reach the jump-off point for the West, a family from the East of the United States could either buy a steamboat passage to Missouri for themselves, their wagons and their livestock or, as happened more often, simply pile everything into a wagon, hitch up a team, and begin their overland trek right in their front yard.
Along the macadamized roads and turnpikes east of the Missouri River, travel was comparatively fast, camping easy, and supplies plentiful. Then, in one river town or another, the neophyte emigrants would pause to lay in provisions. For outfitting purposes, the town of Independence had been preeminent ever since 1827, but the rising momentum of pioneer emigration had produced some rival jump-off points. Westport and Fort Leavenworth flourished a few miles upriver. St. Joseph had sprung up 55 miles to the northwest; in fact, emigrants who went to Missouri by riverboat could save four days on the trail by staying on the paddle wheelers to St. Joe before striking overland.
At whatever jump-off point they chose, the emigrants studied guide books and directions, asked questions of others as green as themselves, and made their final decision about outfitting. They had various, sometimes conflicting, options. For example, either pack animals or two -wheel carts or wagons could be used for the overland crossing. A family man usually chose the wagon. It was the costliest and slowest of the three, but it provided space and shelter for children and for a wife who likely as not was pregnant. Everybody knew that a top-heavy covered wagon might blow over in a prairie wind or be overturned by mountain rocks, that it might mire in river mud or sink to its hubs in desert sand, but maybe if those things happened on this trip, they would happen to someone else. Anyway, most pioneers, with their farm background, were used to wagons.

Around 365 B.C. in ancient Greece, the great teacher Plato told a story about a place called Atlantis. Plato described Atlantis as a continent in the Atlantic Ocean. He said it had been the home of a powerful people who were destroyed when the continent was swallowed by the sea.
Ever since Plato’s time, people have wondered if the story about Atlantis was really true. Was there ever such a place as Atlantis? During the Middle Ages, many people believed in the legend of Atlantis. Some men even made voyages to find the “lost continent”. Later, most people believed Atlantis to be just a myth. Scientists could find no evidence to show that such a place had ever existed.
Ideas change in time, however, for now some scientists think that Atlantis might have been a real place. A Greek professor has offered a new theory. He says that Atlantis was not a continent in the Atlantic Ocean but an island called Thera in the Aegean Sea. The professor says that 3,500 years ago much of Thera collapsed into the sea when a volcano erupted. He thinks that before the explosion Thera had been the home of a people called Minoans. The Minoans were sea traders who ruled the Aegean Sea from 2,000
B.C. to 1,250 B.C.
Scientist who have come to investigate Thera have found an ancient city buried beneath volcanic ash and stone. It appears that the people who lived in the city had an advanced civilization. They were probably Minoans.
Is Thera the “lost continent” of Atlantis? No one may ever know for certain. Atlantis may remain a riddle without an answer.

In 1826, a Frenchman named Niépce needed pictures for his business. He was not a good artist, so he invented a very simple camera. He put it in a window of his house and took a picture of his yard. That was the first photograph.
The next important date in the history of photography was 1837. That year, Daguerre, another Frenchman, took a picture of his studio. He used a new kind of camera and a different process. In his pictures, you could see everything clearly, even the smallest details. This kind of photograph was called a daguerreotype.
Soon, other people began to use Daguerre's process. Travelers brought back daguerreotypes from all around the world. People photographed famous buildings, cities, and mountains.
In about 1840, the process was improved. Then photographers could take pictures of people and moving things. The process was not simple and photographers had to carry lots of film and processing equipment. However, this did not stop photographers, especially in the United States. After 1840, daguerreotype artists were popular in most cities.
Matthew Brady was one well-known American photographer. He took many portraits of famous people. The portraits were unusual because they were lifelike and full of personality. Brady was also the first person to take pictures of a war. His 1862 Civil War pictures showed dead soldiers and ruined cities. They made the war seem more real and more terrible.
In the 1880s, new inventions began to change photography. Photographers could buy film ready- made in rolls, instead of having to make the film themselves. Also, they did not have to process the film immediately. They could bring it back to their studios and develop it later. They did not have to carry lots of equipment. And finally, the invention of the small handheld camera made photography less expensive. With a small camera, anyone could be a photographer. People began to use cameras just for fun.
They took pictures of their families, friends, and favorite places. They called these pictures "snapshots".
Documentary photographs became popular in newspapers in the 1890s. Soon magazines and books also used them. These pictures showed true events and people. They were much more real than drawings.
Some people began to think of photography as a form of art. They thought that photographycould do more than show the real world. It could also show ideas and feelings, like other art forms.

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:
Dark matter in the universe is believed by some scientists to be a substance that is not readily observable because it does not directly refract light or energy. Its existence can only be deduced because of the effect that it has on surrounding matter. In fact, some members of the scientific community have argued that dark matter does not actually exist. Others, however, believe in its existence, in part because the scientific community does not have a complete understanding of gravita science. On the other hand, some would argue that it is the understanding of gravitational science that leads most scientists to believe in the existence of dark matter, because without dark matter, there are many cosmological phenomena
that are difficult to explain.
For example, dark matter in the universe may have a peculiar effect on the Milky Way galaxy. Some scientists believe that the interaction between dark matter and other smaller, nearby galaxies is causing the Milky Way galaxy to take on a warped profile. It has been asserted that not only does dark matter exist, it may also be responsible for the Milky Way’s unusual shape. The interaction referenced involves two smaller galaxies near the Milky Way, called Magellanic clouds, moving through an enormous amount of dark matter, which, in effect, enhances the gravitational pull that the two Magellanic clouds could have on the Milky Way and other surrounding bodies. Without the existence of the dark matter, the Magellanic clouds would not have sufficient mass to have such a strong effect on the bend of the Milky Way galaxy.
The strongest evidence for the validity of this hypothesis rests in Newtonian physics, and the hypothesis that anything with mass will exert a gravitational pull. The Milky Way and other galaxies with peculiar warped shapes are being molded by a gravitational force. However, there is nothing readily observable with sufficient mass that could cause such a high level of distortion via gravitational pull in the vicinity of the Milky Way. Therefore, something that is not easily observed must be exerting the necessary force to create the warped shape of the galaxy.
Aaron Romanowsky and several colleagues have questioned the effect that dark matter might have on galaxies. They point to the existence of several elliptical galaxies surrounded by very little dark matter as evidence that dark matter is not, in fact, the cause of the warped galaxies. While they do not claim that their findings should be interpreted to conclude that dark matter does not exist, they apparently believe that the results of their studies cast doubt on some of the conventional theories of galaxy formation and manipulation.
Several models constructed by researchers from the University of California at Berkeley, however, point to the idea that dark matter is the most likely explanation for the distorted shape of the Milky Way and other galaxies. Using computer models, they have mapped the likely interactions between certain galaxies and the surrounding dark matter, and those models have shown not only the possibility that dark matter is responsible for the warped shape of the Milky Way, but that the relationship between the dark matter and the Magellanic clouds is dynamic; the movement of the clouds through the dark matter seems to create a wake that enhances their gravitational influence on the Milky Way.

What does the passage offer as evidence for the existence of dark matter?

Read the passage below and choose one correct answer for each question.

In developing countries, people are sometimes unaware of the importance of education, and there is economic pressure from those parents who prioritize their children's, making money in the short term over any long-term benefits of education. Recent studies on child labor and, poverty have suggested that when poor families reach a certain economic threshold where families are able to provide for their basic needs, parents return their children to school. This has been found to be true, once the threshold has been breached, even if the potential economic value of the children's work has increased since their return to school.

Other problems are that teachers are often paid less than other professions; a lack of good universities and a low acceptance rate for good universities are evident in countries with a relatively high population density.

India has launched EDUSAT, an education satellite that can reach remote parts of the country at a greatly reduced cost. There is also ail initiative supported by several major corporations to develop a $100 laptop. The laptops have been available since 2007. The laptops, sold at cost, will enable developing countries to give their children a digital education. In Africa, an "e-school program" has been launched to provide all 600,000 primary and high schools with computer equipment, learning materials and internet access within 10 years. Volunteer groups are working to give more individuals opportunity to receive education in developing countries through such programs as the Perpetual Education Fund.

Environmental pollution is one of the impacts of human activities on the Earth. Pollution occurs when pollutants contaminate the natural surroundings; which brings about changes that affect our normal lifestyles adversely. Pollution disturbs our ecosystem and the balance in the environment. Pollution occurs in different forms; air, water, soil, radioactive, noise, heat/ thermal and light Let us discuss the causes and effects of air pollution on mankind and the environment as a whole.
Air pollution is the most prominent and dangerous form of pollution. It occurs due to many reasons. Excessive burning of fuel which is a necessity of our daily lives for cooking, driving and other industrial activities; releases a huge amount of chemical substances in the air every day; these pollute the air. Smoke from chimneys, factories, vehicles or burning of wood basically occurs due to coal burning; this releases sulphur dioxide into the air making it toxic.
The effects of air pollution are evident too. The increase in the amount of CO2 in the atmosphere leads to smog which can restrict sunlight from reaching the earth. Thus, preventing plants in the process of photosynthesis. Gases like sulfur dioxide (SO2) and nitrogen oxide (NO) can cause acid rain.
The decrease in quality of air leads to several respiratory problems including asthma or lung cancer. Chest pain, congestion, throat inflammation, cardiovascular disease, respiratory disease are some of diseases that can be caused by air pollution.
The emission of greenhouse gases particularly CO2 is leading to global warming. Every other day new industries are being set up, new vehicles come on roads and trees are cut to make way for new homes. All of them, in direct or indirect way lead to increase in CO2 in the environment. The increase in CO2 leads to melting of polar ice caps which increases the sea level and pose danger for the people living near coastal areas.
Ozone layer is the thin shield high up in the sky that stops ultra violet rays from reaching the  earth. As a result of human activities, chemicals, such as chlorofluorocarbons (CFCs), were released into the atmosphere which contributed to the depletion of ozone layer.

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. 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.
