Nuts could be the key to keeping slim, according to new research. Scientists from Harvard University and Harvard Medical School say that replacing and unhealthy snack with half a daily _____ (1) of nuts could slow weight gain in people as they get older. Walnuts ____________ (2) particular appeared to offer good results and were linked to a 15% lower risk of obesity. Researchers conducted a long-term study which followed 51,529 male health professionals aged 40 to 5, 121,700 nurses aged 35 to 55 and 16,686 nurses aged 24 to 44. Participants had their weight ____________ (3) every four years and were asked how often they had eaten nuts. They also had to report their exercise every two years. The findings, ___________________ (4) in the online journal BMJ Nutrition, Prevention and Health, showed that increasing nut consumption was associated with less risk of putting on two or more kilos over a four-year period. However, the researchers say the study is ________ (5) and therefore cannot establish a definite cause

U.S. population could increase from 323 million in 2016 to as high as 447 million by 2060—or fall as low as 320 million. It depends on how many immigrants are admitted over the next four decades, according to new report from the Census Bureau. According to the report, if current levels of immigration are maintained, the U.S. population will grow to 404 million by 2060. If immigration is cut in half, the population will rise to 376 million. If immigration increases by 50 percent, the population expands to 447 million. And if all immigration were to be halted now, the U.S. population would peak at around 332 million in 2035 and drop to 320 million in 2060. In the high-immigration scenario, the proportion of foreign-born residents would rise by 2060 to 21.6 percent of the population. If immigration is halted, the forecast shows only 4.6 percent of the population in 2060 being foreign-born. In all of the scenarios, the median age of the U.S. population rises from 37.9 to more than 40. The report projects that the number of people identifying as “white alone”—that is, respondents who check only the white ethnicity box on census forms—will continue to rise in the main, high, and low immigration scenarios. This increase results from the Census Bureau’s expectation that the children of Hispanic immigrants will probably, like the children of Italian, Polish, Greek, and other earlier immigrant groups, choose to identify increasingly as white. But the share of the population in the white alone category will decline in each scenario, due to faster increases in the numbers of Americans in the other racial and ethnic groups. America is an ideal, not a tribe

Today, population growth largely means urban population growth. UN projections  show the world’s rural population has already stopped growing, but the world can expect to add close to 1.5 billion urbanites in the next 15 years, and 3 billion by 2050. How the world meets the challenge of sustainable development will be intimately tied to this process.  For many people, cities represent a world of new opportunities, including jobs. There is a powerful link between urbanization and economic growth. Around the world, towns and cities are responsible for over 80 per cent of gross national product. While urban poverty is growing around the world, this is largely because many people – including the poor – are moving to urban areas.  The opportunities there extend beyond just jobs. Cities also offer greater opportunities for social mobilization and women’s empowerment. Many young people, especially young women, regard the move to cities as an opportunity to escape traditional patriarchy and experience new freedoms. Urban areas also offer greater access to education and health services, including sexual and reproductive health care, further promoting women’s empowerment and the realization of their reproductive rights. This contributes to significantly reduced fertility in urban areas, changing the trajectory of overall population growth.  The urbanization process – which is particularly pronounced in Africa and Asia, where much of the world’s population growth is taking place – is also an enormous opportunity for sustainability, if the right policies are put in place. Urban living has the potential to use resources more efficiently, to create more sustainable land use and to protect the biodiversity of natural ecosystems. Still, the face of inequality is increasingly an urban one. Too many urban residents grapple with extreme poverty, exclusion, vulnerability and marginalization. Urban land is expanding much faster than urban population, a phenomenon known as urban sprawl. It is driven in part by increasing urban land consumption by the wealthy and the increasing separation of rich and poor communities within cities. Sprawl undermines the efficiencies of urban living, and it marginalizes poor people in remote or peripheral parts of cities, often in dense informal settlements or slums.  This phenomenon can eliminate the very opportunities people seek when they move to cities. Many people in slums lack ready access to health facilities. Others rely on private, unregulated providers for health services that are free in rural areas. In some urban slums, poor women have fertility rates closer to those of rural women. The urban poor also face risky and unhealthy living conditions, such heavy pollution or high vulnerability to disasters.  The total estimated number of slum dwellers is rising – from over 650 million in 1990 to about 863 million in 2012. Almost 62 per cent of the urban population in sub-Saharan Africa lived slums in 2010, the highest proportion of any region. But slum growth is not the same as urbanization. Most evidence suggests that global urbanization is an inevitable trend, while slum growth results from the decisions to limit poor people’s access to cities, through limited service provision to informal settlements or by forced evictions and resettlement of the urban poor to peripheral or under-serviced areas. 
2. The word “sustainable” in the first paragraph is closest in meaning to _____

Swine influenza (also called swine flu, hog flu and pig flu) is an infection of a host animal by any one of several specific types of microscopic organisms called "swine influenza virus". A swine influenza virus (SIV) is any strain of the influenza family of viruses that is usually hosted by (is endemic in) pigs. As of 2009, the known SIV strains are the influenza c virus and the subtypes of the influenza A virus known as HI N1, H1N2, H3N1, H3N2 and H2N3. Swine influenza is common in pigs in the mid-western United States (and occasionally in other states), Mexico, Canada, South America, Europe (including the UK, Sweden and Italy) Kenya Mainland China, Taiwan Japan and other parts of eastern Asia.

Transmission of swine influenza vims from pigs to humans is not common and does not always cause human influenza, often only resulting in the production of antibodies in the blood. The meat of the animal poses no risk of transmitting the virus when properly cooked. If transmission does cause human influenza, it is called zoonotic swine flu. People who work with pigs, especially people with intense exposures, are at increased risk of catching swine flu. In the mid-20th century, identification of influenza subtypes became possible. This allows accurate diagnosis of transmission to humans. Since then, fifty confirmed transmissions have been recorded. Rarely, these strains of swine flu can pass from human to human. In humans, the symptoms of swine flu are similar to those of influenza and of influenza-like illness in general namely chills fever sore throat, muscle pains severe headache, coughing, weakness and general discomfort.

The 2009 flu outbreak in humans known as "swine flu" is due to a new strain of influenza A virus subtype H1N1 that contains genes closely related to swine influenza. The origin of this new strain is unknown. However, the World Organization for Animal Health (OIE) reports that this strain has not been isolated in pigs. This strain can be transmitted from human to human, and causes the normal symptoms of influenza

Since 2015, the annual Women in the Workplace benchmarking report has covered over 600 of the largest U.S. companies employing more than 20 million people, and has individually surveyed more than a quarter-million employees. That research base shows us how better sponsorship and improved training to counter unconscious bias can speed our progress to gender equality. And it reveals the changes that have—and haven’t—happened over the past few years. There are some bright spots. In 2019, nearly 90% of respondent companies say that gender equality is a top priority. Almost half report having at least three women on their leadership team And greater openness to flexible working is allowing many more women— and men—to work remotely. But some areas are proving stubbornly difficult to improve. Most strikingly, it’s much harder for women than men to achieve their first promotion. Indeed, for every 100 men who step up from an entry level position to a management role, only 78 women—and just 52 black women—will receive the same promotion. Over five years, that gap adds up to a difference of one million promoted women, with lasting repercussions further along the talent funnel: only 1 in 5 C-suite members are women, and only 1 in 25 are women of color. Moving up the ladder, the 21% figure for women in the C-suite is also less encouraging than it seems. Women are much more likely to have a staff role—chief human resources officer, general counsel, or CFO—while men take more of the line roles, running the largest business units with their own P&L lines. It’s rare for any leader in a staff role to be promoted to CEO.

If you were going to choose a job that involves travel, what would be your first choice? There are many jobs available today that give people opportunities to travel. Although may traveling careers sound fantastic, they also have disadvantages. Being an au pair is an excellent way to not only go to different countries, but to live in different places around the world and really get a feel for the culture. Au pairs lives with the families they are placed with and take of children. Many parents include au pairs in family events and vacations, so they experience many aspects of the new culture while on the job. However, many of the activities are centered around the children, so they may not get to experience many things that interest adults. For people who want a bit more freedom working abroad, being an English teacher maybe a good choice. There are English teaching jobs in almost countries in the world. People teaching English in other countries often have a chance to travel on the weekends around the country. One drawback is that many teachers often wind up hanging out with other English teachers, and they don’t have time to learn the country’s language. The nickname “roadie” implies that this job involves life on the road. Roadies are people who work and travel with bands and provide technical support. Roadies can be lighting and stage crew who set up the stage and break it down before and after events. They can also be technicians helping band members with their instruments. International tours take a band’s crew to cities around the world, often requiring air travel. However, the crew doesn’t get much time off, so they may travel to several countries without seeing much besides concert venues and hotels. Similarly, flight attendants often travel to cities around the world, but they don’t see much besides the inside of airplanes and hotels. However, when they do have time off, they can often fly at no cost, and family member can sometimes fly free as well. Its is widely thought that a flight attendant job is glamorous, but flight attendants must deal with travel hassles, as well as security issues. All jobs gave advantages and disadvantages whether or not you travel for work, so if you have the travel bug, keep these jobs in mind for the future.

Set aside time each day Most of us can find 15 minutes or half an hour each day for some specific regular activity. It may be a free period or a regular wait, stay in the queue for a bus or meal - even while eating breakfast. One famous surgeon always made it a rule to spend at least 15 minutes on general reading before he went to sleep each night. Whether he went to bed at 10:00 p.m or 2:30 a.m. made no difference. Even if you cannot keep to this kind of discipline, it is a good idea to make sure you always have a general interest book in your pocket. Don’t forget it should be a book which entertains you and the English must not be too difficult for you. Checking your progress through pacing Nearly all speed reading courses have a "pacing element - some timing device which lets the student know how many words a minute he is reading. You can do this simply by looking at your watch every 5 or 10 minutes and noting down the page number you have reached. How do you know when 5 minutes have passed on your watch if you are busy reading the book? Well, this is difficult at first. A friend can help by timing you over a set period. Pace yourself every three or four days, always with the same kind of easy, general interest book. You should soon notice your habitual w. p. m rate creeping up. Check comprehension Obviously there is little point in increasing your w. p. m rate if you do not understand what you are reading. When you are consciously trying to increase your reading speed, stop after every chapter (if you are reading a novel) or every section or group of ten or twelve pages (if it is a textbook) and ask yourself a few questions about what you have been reading. If you find you have lost the thread of the story, or you cannot remember clearly the details of what was said, re-read the section or chapter. “Lightening speed” exercise Take 4 or 5 pages in the general interest book you happen to be reading at the time. Read them as fast as you possibly can. Do not bother about whether you understand or not. Now go back and read them at what you feel to be your normal w. p. m rate, the rate at which you can comfortably understand. After a “lightening speed” read through (probably around 6 w. p. m) you will usually find that your normal speed has increased -  perhaps by as much as 50 -100 w. p. m.

Read the following passage and choose the best answer (A, B, C, D):
Thirty years after ghostwriting Donald Trump’s The Art of the Deal, Tony Schwartz described the experience as like putting lipstick on a pig. He felt a “deep sense of remorse” at helping bring the man who would become president gain wider attention. This week, the writer Natalie Beach joined the grand tradition of ghostwriters speaking out about their subjects, with a deeply intimate essay in the Cut laying out how she used to ghost everything for her former friend and controversial “influencer” Caroline Calloway: from Instagram captions to the aborted book that once attracted a $375,000 (£300,000) publishing deal, until their relationship broke down irretrievably. Beach’s account says that after the pair put the book proposal together, the influencer felt unable to write it. Beach says she “bought us time with the publishers by writing a quarter of the manuscript by myself”. As a ghostwriter himself, Crofts questions the ethics of speaking out about his subjects’ lives. “I do think Tony Schwartz shouldn’t have come out and said anything about Trump, because you’ve taken the money. It’s like a lawyer: if you find that the person you’re representing is a murderer you can’t then go around bewailing the fact you defended them – that was your job,” he said. “But I think he made Trump, I don’t think Trump would be president if he hadn’t written that book for him, because he’d never have got The Apprentice without the book, and the presidency without The Apprentice. So it must be weighing heavily on his conscience.”  Ghostwriters must be good at several things – being amenable to being steered by a subject, while also being firm enough to guide them away from tangents and uninteresting details. But the most important thing in ghostwriting, says Crofts, is absence of ego. “Which is maybe what went wrong [with Calloway] – Natalie isn’t a born ghost, she’s a writer herself. She was really young and well out of her depth, completely swamped by this girl’s flamboyance,” he says. “Ghostwriters do attract a lot of fantasists and people who have ideas way above the likelihood of success. They always think their story is fantastically interesting and going to be a bestseller. You’re always dealing with people with larger-than-life egos, so there’s always a danger you’re going to run up against someone who is impossible to manage.”  
3. According to paragraph 1, what thought or feeling compelled Tony Schwartz to confess after thirty years?

Mark the letter A, B, C, or D on your answer sheet to indicate the undelined part that needs correction in each of the following questions:
In the USA, the UK and many other countries, a lot of babies were born in the “baby boom” of the late 1940s and 1950s; after that the birth-rate fell. Baby boomers have now retired, or are approaching retirement, and this is causing headaches for many organizations: there are not enough people to succeed their top managers when they retire.
Does your organization have key staff who can’t easily be replaced? A CEO or financial director, perhaps, or a technical expert with knowledge that nobody else in the organization has. If your answer is “yes”, what will happen when they retire, or leave for another company? Will you wait until the last moment before looking for someone to replace them? Or is your organization thinking about likely future changes now, as it should be, and making plans, so that there is likely to be someone ready to replace the person leaving? If the answer is that you are planning ahead, your organization is carrying out succession planning.
Succession planning means looking inside the organization for “high-fliers” - current staff members with the potential to fill key positions - and planning the training, responsibilities and promotion they need, to make them ready when a senior vacancy occurs - which may not be for several years. The company benefits by being able to make an internal promotion when a key person leaves, and in the meantime it benefits by developing the skills of its high-fliers and encouraging them to stay. And the high-fliers benefit, because they achieve their full potential, a career is planned for them within the organization, and they can look forward to a senior post in time.
The training program planned for the high-fliers will help them to develop the leadership skills they need for more senior roles, skills such as planning long-term strategies. A career path is also planned, so that each high-flier moves into a number of different positions over a few years, to gain the experience and know ledge they need.
Sometimes a staff member is chosen as a potential successor to a particular senior manager, but a better method is for organizations to select a number of high-fliers, and prepare them for a range of senior roles. An organization can’t be certain when a particular senior manager will leave. Having a group of people being prepared fee top positions makes it easier to replace someone who leaves unexpectedly, and also means that there are other people available if a high-flier leaves the company.

Sophia is a humanoid robot developed by Hong Kong-based company Hanson Robotics. She has been designed to learn and adapt to human behavior and work with humans, and has been interviewed around the world. In October 2017, she became a Saudi Arabian citizen, the first robot to receive citizenship of a country. According to herself, Sophia was activated on April 19, 2015. She is modeled after actress Audrey Hepbum,and is known for her human-like appearance and behavior compared to previous robotic variants. According to manufacturer, David Hanson, Sophia has artificial intelligence, visual data processing and facial recognition. Sophia also imitates human gestures and facial expressions and is able to answer certain questions and to make simple conversations on predefined topics (e.g. on the weather). The robot uses voice recognition technology from Alphabet Inc. (parent company of Google) and is designed to get smarter over time. Sophia’s intelligence software is designed by SingularityNET. The AI program analyses conversations and extracts data that allows her to improve responses in the future. It is conceptually similar to the computer program ELIZA, which was one of the first attempts at simulating a human conversation. Hanson designed Sophia to be a suitable companion for the elderly at nursing homes, or to help crowds at large events or parks. He hopes that she can ultimately interact with other humans sufficiently to gain social skills. Sophia has been interviewed in the same manner as a human, striking up conversations with hosts. Some replies have been nonsensical, while others have been impressive, such as lengthy discussions with Charlie Rose on 60 Minutes. In a piece for CNBC, when the interviewer expressed concerns about robot behavior, Sophia joked that he had “been reading too much Elon Musk, and watching too many Hollywood movies”. Musk tweeted that Sophia could watch The Godfather and suggested “What’s the worst that could happen?”. On October 11, 2017, Sophia was introduced to the United Nations with a brief conversation with the United Nations Deputy Secretary-General, Amina J. Mohammed. On October 25, at the Future Investment Summit in Riyadh, she was granted Saudi Arabian citizenship, becoming the first robot ever to have a nationality. This attracted controversy as some commentators wondered if this implied that Sophia could vote or marry, or whether a deliberate system shutdown could be considered murder. Social media users used Sophia’s citizenship to criticize Saudi Arabia’s human rights record.

Social networking sites such as Facebook and MySpace do not help you make more  genuine close friends, according to a survey by researchers who studied how the websites are changing the nature of friendship networks. Although social networking on the internet helps people to collect hundreds or even thousands of acquaintances, the researchers believe that face to face contact is nearly always necessary to form truly close friendships.  “Although the numbers of friends people have on these sites can be massive, the actual number of close friends is approximately the same in the face to face real world,” said psychologist Will Reader, from Sheffield Hallam University. Social networking websites such as Facebook, Bebo and MySpace have taken off rapidly in recent years. Facebook was launched initially in 2004 for Harvard University members but has since expanded to more than 34 million users worldwide. MySpace, which was set up in 2003, has more than 200 million users and was bought by Rupert Murdoch’s News Corporation in 2005 for $580m (£285m). Previous research has suggested that a person’s conventional friendship group consists of around 150 people, with five very close friends but larger numbers of people whom we keep in touch with less regularly. This figure is so consistent that scientists have suggested it is determined by the cognitive constraints of keeping up with large numbers of people. But Dr. Reader and his team have found that social networking sites do allow people to stretch this figure. The team asked more than 200 people to fill in questionnaires about their online networking, asking for example how many online friends they had, how many of these were close friends and how many they had met face to face. The team found that although the sites allowed contact with hundreds of acquaintances, as with conventional friendship networks, people tend to have around five close friends. Ninety per cent of contacts whom the subjects regarded as close friends were people they had met face to face. “People see face to face contact as being absolutely imperative in forming close friendships,” added Dr. Reader. He told the British Association Festival of Science in York that social networking sites allow people to broaden their list of nodding acquaintances because staying in touch online is easy. “What social network sites can do is decrease the cost of maintaining and forming these social networks because we can post information to multiple people,” he said.  But to develop a real friendship we need to see that the other person is trustworthy, said Dr. Reader. "What we need is to be absolutely sure that a person is really going to invest in us, is really going to be there for us when we need them … It’s very easy to be deceptive on the internet."

Read the following passage and choose the best answer (A, B, C, D):
A satellite is best understood as a projectile, or an object that has only one force acting on it — gravity. Technically speaking, anything that crosses the Karman Line at an altitude of 100 kilometers (62 miles) is considered in space. However, a satellite needs to be going fast — at least 8 km (5 miles) a second — to stop from falling back down to Earth immediately. If a satellite is traveling fast enough, it will perpetually “fall” toward Earth, but the Earth’s curvature means that the satellite will fall around our planet instead of crashing back on the surface. Satellites that travel closer to Earth are at risk of falling because the drag of atmospheric molecules will slow the satellites down. Those that orbit farther away from Earth have fewer molecules to contend with. There are several accepted “zones” of orbits around the Earth. One is called lowEarth-orbit, which extends from about 160 to 2,000 km (about 100 to 1,250 miles). This is the zone where the ISS orbits and where the space shuttle used to do its work. In fact, all human missions except for the Apollo flights to the moon took place in this zone. Most satellites also work in this zone. Geostationary or geosynchronous orbit is the best spot for communications satellites to use, however. This is a zone above Earth’s equator at an altitude of 35,786 km (22,236 mi). At this altitude, the rate of “fall” around the Earth is about the same as Earth’s rotation, which allows the satellite to stay above the same spot on Earth almost constantly. The satellite thus keeps a perpetual connection with a fixed antenna on the ground, allowing for reliable communications. When geostationary satellites reach the end of their life, protocol dictates they’re moved out of the way for a new satellite to take their place. That’s because there is only so much room, or so many “slots” in that orbit, to allow the satellites to operate without interference. While some satellites are best used around the equator, others are better suited to more polar orbits — those that circle the Earth from pole to pole so that their coverage zones include the north and south poles. Examples of polar-orbiting satellites include weather satellites and reconnaissance satellites

It was practically the anthem for 2019 World Series, with tens of thousands of Washington Nationals fans clapping in unison and belting out “Baby Shark, doo-doo doo-doo doo-doo.” In Lebanon, it became a rallying cry after a video of protesters singing to soothe a frightened toddler went viral. And in many other places, the earworm has drawn ridicule, with late-night comedian Jimmy Kimmel suggesting its creator should be jailed for life. To the contrary, the catchy tune about a family of sharks has become so lucrative that the Korean family behind it is now sitting on a rapidly growing multimillion-dollar fortune. Kim Min-seok co-founded closely held SmartStudy Co. in 2010, and five years later its children’s educational brand, Pinkfong, released “Baby Shark”. His father runs Samsung Publishing Co., which also owns part of the startup. The family fortune, based on stakes held by Kim’s immediate relatives in those two companies, is now about $125 million – much of it thanks to the song. However, when asked, SmartStudy declined to comment on the family’s wealth. Shares of Samsung Publishing soared 89% the week the World Series began as local media reported on the song’s surging popularity among U.S. baseball fans. National outfielder Gerardo Parra began using it as his walk-up music, leading to crowd sing-alongs with shark-jaw gestures, scenes that echoed across TVs as the team broke out of an early season slump. They rode the wave all the way to the championship. Kim, 38, hardly set out to write a hit global song. After working at gaming companies including Nexon and developing content for kids at Samsung Publishing, he co-founded SmartStudy to focus on the growing market for educational content for smartphones.
3. Which of the following is NOT correct about Pinkfong?
