Polar bears are being increasingly threatened by the effects of climate change, but their disappearance could have (26) _______ consequences. They are uniquely adapted to the extreme conditions of the Arctic Circle, (27) _______ temperatures can reach -40°C. One reason for this is that they have up to 11 centimetres of fat underneath their skin. Humans with comparative levels of adipose tissue would be considered obese and would be likely to suffer from diabetes and heart disease. (28) _______ the polar bear experiences no such consequences. A 2014 study by Shi Ping Liu and colleagues sheds light on this mystery. They compared the genetic structure of polar bears with (29) _______ of their closest relatives from a warmer climate, the brown bears. This allowed them to determine the genes that have allowed polar bears to survive in one of the toughest environments on Earth. Liu and his colleagues found the polar bears had a gene known as APOB, which reduces levels of low-density lipoproteins (LDLs) - a form of 'bad' cholesterol. In humans, mutations of this gene are (30) _______ with increased risk of heart disease. Polar bears may therefore be an important study model to understand heart disease in humans

Many people see large urban cities as a wonder of human imagination and creativity. They represent how far the human population has come in terms of community development. Despite its positive things, there are also negatives from urbanization on the physical health of humans living.
As it would be expected, developing countries tend to see more negative physical health effects than modern countries in regard to urbanization. One example of a developing country experiencing these problems is China. China is a country that in the past 30-40 years went from being an agrarian based society to a significant industrialized country. This industrialization has in effect caused the need for more centralized cities, centralized meaning having lots of jobs and living spaces within a close proximity. In most recent decades, since China’s change to being more of an industrial based economy, the country has experienced record high numbers of people migrating within its borders. In effect, the number of cities with over 500,000 people has more than doubled. These migrations are typically of people from rural areas of China moving to the new urban areas. Due to this large influx in the urban population, there are many possibilities for health challenges among these people. One very common and fairly obvious negative aspect of highly congested urban areas is air pollution. It could include particulate matter, most commonly attributed to industrial plants and refineries waste, or chemicals like CO2 or Methane. Due to a vast number of people in these urbanized cities, the air pollution is known to be very extreme. These conditions can lead to many different health problems such as: Asthma, cardiovascular problems or disease. When exposed to these conditions for a prolonged period of time, one can experience even more detrimental health effects like: the acceleration of aging, loss of lung capacity and health, being more susceptible to respiratory diseases, and a shortened life span. Another way that urbanization affects the populations’ health is people’s change in diet. For instance, urban cities tend to have lots of accessible, quick, and easy to get food. This food is also more than likely not as high quality as well as contains a large amount of sodium and sugar. Because this food is so accessible, people tend to eat it more. This increase in consumption of low-quality food can then lead to diabetes, hypertension, heart disease, obesity, or many other health conditions.

Despite predictions that the traditional media were going to disappear in the internet age, newspapers, the radio and television have managed to survive. However, their survival has come at a price. Digital technology has given birth to social media, tools that allow ordinary people to create, share and exchange information without the need for the usual news channels. Moreover, social media is also attracting a large share of advertisers' money away from the traditional media. As a result, newspapers, the radio and television are always looking for ways to hurt their new rival and they are more than happy to publish stories that play on people's fears about how untrustworthy and unsafe social media is. As all football fans know, the sports media has to work harder between matches to fill their pages and sites. The most popular method of doing this is by speculating about the players that clubs might buy or sell, especially talented foreigners. However, many readers often suspect that these stories are the products of lazy journalism and, if not completely false, contain very little truth and a lot of exaggeration. One Irish football fan decided to find out by using social media to invent Masal Bugduv, a sixteen-year old football superstar from the small Eastern European country of Moldova. The fan set up a Wikipedia page for the player that explained that Bugduv had already played for his national team and that his nickname was 'Massi'. He then wrote false press agency stories that claimed Bugduv would soon join Arsenal and sent them to sports blogs. The blogs accepted the stories as true, but the big surprise came when The Times newspaper included an article entitled Football's Top 50 Rising Stars. At number thirty on the list was 'Moldova's finest', sixteen-year-old Masal Bugduv, who had been linked with Arsenal and 'plenty of other top clubs as well.' While most people would agree that the traditional press should warn people about the dangers of new technology, it is also good to know that social media can expose the unprofessional practices of some journalists. The more they zoom in on each other's unacceptable practices, the better for the readers
3. According to paragraph 2, which aspect was it that the Times newspaper got wrong about Masal Bugduv?

Sylvia Earle is an underwater explorer and marine biologist who was born in the USA in 1935. She became interested in the world’s oceans from an early age. As a child, she liked to stand on the beach for hours and look at the sea, wondering what it must be like under the surface. When she was 16, she finally got a chance to make her first dive, which motivated her to become an underwater explorer. Since then, she has spent more than 6,500 hours under water, and has led more than seventy expeditions worldwide. She has also made the deepest dive ever, reaching a record – breaking depth of 381 metres.
In 1970, she became famous around the world when she became the caption of the first all- female team to live under water. The team spent two weeks in an underwater “house”. The research they carried out showed the damage that pollution was causing to marine life, and especially to coral reefs. Her team also studied the problem of over- fishing. Fishing methods meant that people were catching too many fish, Earle warned, and many species were in danger of becoming extinct. Since then she has written several books and magazine articles in which she suggests ways of reducing the damage that is being done to the world’s oceans. One way, she believes, is to reply on fish farms for seafood, and reduce the amount of fishing that is done out at sea. Although she no longer eats seafood herself, she realizes the importance it plays in our diets, It would be wrong to tell people they should stop eating fish from the sea, she says. However, they need to reduce the impact they are having on the ocean’s supplies.

Stella McCartney was born in 1972, the daughter of pop star Sir Paul McCartney. She is the youngest of three sisters. One sister is a potter and the other sister does the same job as their mother used to do - she works as a photographer. Stella's brother, James, is a musician. Stella first hit the newspaper headlines in 1995 when she graduated in fashion design from art college. At her final show, her clothes were modeled by her friends, Naomi Campbell and Kate Moss, both well-known models. Unsurprisingly, the student show became front-page news around the world. Stella hadn't been in the news before as a fashion designer but she had spent time working in the fashion world since she was fifteen. In March 1997, Stella went to work for the fashion house Chloe. People said the famous fashion house had given her the job because of her surname and her famous parents but Stella soon showed how good she was. She designs clothes which she would like to wear herself, although she's not a model, and many famous models and actors choose to wear them. In 2001 Stella started her own fashion house and has since opened stores around the world and won many prizes. A lifelong vegetarian, McCartney does not use any leather or fur in her design. Instead, she uses silk, wool and other animal-derived fabrics.

Maria Alcalá of Madrid speaks for many Mediterranean people when she says that “a meal without olive oil would be a bore.” No one knows when the Mediterranean civilizations initially fell in love with olives. That occurred before recorded history. However, there is evidence that the cultivation of olive trees began in countries around the Mediterranean Sea in approximately 4000 B.C., and 2,000 years after that people in the eastern Mediterranean region began to produce oil from olives. The Mediterranean still accounts for 99 percent of all world olive oil production. From ancient times until today, the basic process of producing the oil is the same. First, whole olives are crushed. Then, the liquid is separated from the solids. After that, the valuable oil is separated from the water. Many olive growers maintain their ancient traditions and still harvest the olives by hand. “We harvest in the traditional way,” says Don Celso, an olive farmer from Tuscany, Italy. "It would be less expensive to do it with machines, but it's more a social thing. Twenty people come to help with the harvest, and we pay them in oil." Olive oil has had a variety of uses through its long history. In ancient times, olive oil was used as money and as medicine. It was even used during war-heated up and dropped down on attackers. It is still used in religious ceremonies. It is great for protecting the freshness of fish and cheese. There are even olive oil lamps and olive oil soaps. Olive oil enhances the lives of people everywhere. Its benefits, recently confirmed by science, were already understood in ancient times. Mediterranean people are happy to share their secret with the world.
