Chances are that your next CEO will be a she and your next congressman will be a congresswoman. After thousands of years of oppression, women across the world are occupying key positions in all spheres of society. The ever-evolving human desire drives the development of men and women alike. Over the past 60 years, we have witnessed a conspicuous change in women’s desire. Women wish to be less and less involved in household management and child care, and are increasingly expanding their involvement in other areas of society. At the same time, the world is pushing towards greater equality, and women assume roles and responsibilities previously only filled by men. Technology also plays a significant role in helping free up women’s time. Just as diapers and baby formula were a tremendous help for mothers, emerging robotics and artificial intelligence solutions will reduce the burden of household management to a level we have never seen. As the world becomes more interdependent, it demands the intervention of women, as though it were asking them to put their unique qualities into practice. A woman’s character is much more responsible, stable and consistent. She is capable of absorbing many changes and coping with long-term challenges — a quality that comes from her natural ability to carry an embryo and develop life within her. A man, on the other hand, is better at short-term moves. A woman is capable of holding onto a large number of tasks as well as carry them out successfully. A man, on the other hand, is more successful in linear processes aimed at a narrow goal. This is why most scientific breakthroughs, for example, manifest through the male brain. Men and women are also different in their attitude to failure in life. Figuratively speaking, a man can be as strong as iron — and yet one blow can break him. The woman is easier to bend — but like a flexible tree branch, she is much harder to break. The mutual completion of each other’s qualities is the key to building a healthy society in the new era. The integration of women in the leadership of society and other systems of human life is becoming necessary. The maternal qualities are expanding from the personal home to the global home. The female nature and drive to create a supportive and embracing environment will be expressed in society in creating healthy and proper conditions for bonding between people.

The biological community changes again as one moves from the city to the suburbs. Around all cities is a biome called the "suburban forest". The trees of this forest are species that are favored by man, and most of them have been deliberately planted. Mammals such as rabbits, skunks, and opossums have moved in from the surrounding countryside. Raccoons have become experts at opening garbage cans, and in some places even deer wander suburban thoroughfares. Several species of squirrel get along nicely in suburbia, but usually only one species is predominant in any given suburb -fox squirrels in one place, red squirrels in another, gray squirrels in a third - for reasons that are little understood. The diversity of birds in the suburbs is great, and in the South, lizards thrive in gardens and even houses. Of course, insects are always present. There is an odd biological sameness in these suburban communities. True, the palms of Los Angeles are missing from the suburbs of Boston, and there are species of insects in Miami not found in Seattle. But over wide stretches of the United States, ecological conditions in suburban biomes vary much less than do those of natural biome. And unlike the natural biomes, the urban and suburban communities exist in spite of, not because of, the climate.

Most of the early houses built in America were suited to farm life, as it was not until cities became manufacturing centers that colonists could survive without farming as their major occupation. Among the earliest farmhouses in America were those built in Plymouth Colony. Generally they consisted of one large rectangular room on the ground floor, called a hall or great room and having a fireplace built into one of the walls, and a loft overhead. Sometimes a lean-to was attached alongside the house to store objects such as spinning wheels, firewood, barrels, and tubs. The furnishings in the great room were sparse and crudely built. Tabletops and chest boards were split or roughly sawed and often smoothed only on one side. Benches took the place of chairs, and the table usually had a trestle base so it could be dismantled when extra space was required. One or two beds and a six-board chest were located in one corner of the room. The fireplace was used for heat and light, and a bench often placed nearby for children and elders, in the area called the inglenook.
The original houses in Plymouth Colony were erected within a tall fence for fortification. However, by 1630 Plymouth Colony had 250 inhabitants, most living outside the enclosure. By 1640, settlements had been built some distance from the original site. Villages began to emerge throughout Massachusetts and farmhouses were less crudely built. Windows brought light into homes and the furnishings and décor were more sophisticated.
As more diversified groups of immigrants settled the country, a greater variety of farmhouses appeared, from Swedish long-style houses in the Delaware Valley to saltbox houses in Connecticut, Dutch-Flemish stone farmhouses in New York, and clapboard farmhouses in Pennsylvania. From Georgian characteristics to Greek revival elements, farmhouses of varied architectural styles and building functions populated the landscape of the new frontier.

Commentary from researchers in the College of Pharmacy at The University of Texas at Austin in the journal Science provide new findings in alcohol use disorder (AUD) research The article, “Compelled to drink: Why some cannot stop,” considers recent findings by researchers Siciliano et al. that discovered individual differences in the activity of neurons in a frontal cortex to brain stem circuit that predicts the later escalation of alcohol drinking to compulsive intake in a mouse model. “These researchers not only defined a new brain circuit involved in compulsive drinking, but showed individual differences at the level of electrical activity in the neurons that comprise this circuit,” Nixon said. “The individual differences in electrical activity predicted which mice would go on to drink compulsively after a binge-like drinking episode despite drinking the same amount of alcohol during that episode.” The research group previously found that this circuit is important for responses to aversive events, and they have now asked why aversive outcomes don’t deter everyone from drinking alcohol. These new findings point to a neurological explanation for why only some mice continue to drink alcohol even when it comes with negative consequences. “They found these differences in circuit activity before mice developed compulsive drinking behavior,” Mangieri said. “In other words, some mice had a biological predisposition that made them susceptible to developing alcohol drinking behaviors that are similar to humans with AUD.” The researchers said the work has important implications. It has potential as a biomarker of propensity to develop severe AUD based on electrical activity. Also, the discovery of this circuit’s role in compulsive drinking suggests that there may be novel pharmacological targets that could be identified and developed for the treatment of AUDs

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.

There’s a direct link between employee satisfaction and customer satisfaction.  Employees are the driving factor behind customer satisfaction. Employee interactions set the tone for a positive or negative customer experience. When employees aren’t happy at work, their interactions with customers can, and almost always will, suffer. Over the course of time, this can have serious repercussions for a business. The place where this becomes the most critical is any business where employees are directly interacting with customers, such as retail or food service. Historically underpaid and overworked, employees in these jobs are tasked with spending their entire shifts serving customers.  This is where employee experience comes in. If even a fraction of a customer experience budget was spent on employee experience, there would be a huge return on investment. One of the easiest ways to enhance employee experience is to ask for and welcome employees’ feedback. They have great insight into customer needs. After all, they’re the ones who are directly interacting with customers and hearing their criticisms and compliments firsthand. Employees can be your biggest asset when it comes to customer satisfaction.  A large part of employee experience revolves around understanding what employees need and want and gaining insight into their work preferences. Another critical piece of the employee experience is training and development. Employees should be equipped with the skills they need to excel at their jobs and have opportunities to continue to learn and develop. They should be able to check in and touch base with their managers to keep track of their progress and discuss any questions or concerns as they arise. Showing employees that you value the work they’re doing is one of the easiest ways to boost their motivation. It can be as simple as saying thank you, to publicly acknowledging and celebrating their contributions. It’s not just the younger generations who crave recognition - no one likes to feel like the work they’re doing is going unnoticed.  It’s time to shift the mindset from employees working just to work, to acknowledging that they’re valuable contributors to a company’s success. Employees need to understand how important their role is and how their work fits into the bigger picture. They need to feel like their voices are being heard and they have respect from their managers. Most importantly, they need to be able to come to work and know that the next eight hours won’t be pure torture.

Four West Indian geckos, with human assistance, have recently entered the United States. The yellowheaded gecko, the ashy gecko, the reef gecko, and the ocellated gecko are presently inhabiting the tropical areas of the Keys and the tip of southern Florida. The Mediterranean gecko also arrived along the Gulf coast some time ago, via the West Indies. The only other geckos in the United States live in the Southwest. In extreme southern California, the leaf-gingered gecko lives

in dry, rocky country and scampers over boulders at night, hiding by day in crevices. It has a slender, tapered tail and stalks insects by raising itself high on its legs, cocking its head, and twitching its tail nervously before leaping on its prey. In courtship, the tail is also waved by the male as he approaches the female.
Although most lizards are excellent climbers, the geckos are able to walk on smooth surfaces with the help of unique clinging devices under the toes. Also, the undersides of most geckos have pads of large scales, each of which bear microscopic hairs with hundreds of branches having minute, blunt ends that press against the surface that the gecko is on, enabling the gecko to cling to almost any surface. Like other lizards, geckos have the ability to shed their tails if attacked by an enemy. They stump heels and a new tail is grown in approximately the same shape as the original. Unlike most lizards, most geckos have no moveable eyelids. The nocturnal geckos have vertical pupils, which contract in bright light. All geckos, except several New Zealand species, lay eggs. The eggs have a tough, white shell and are laid under stones, behind window shutters or under bark.

The poaching crisis wiping out Africa's elephants is costing the continent's economies millions in lost tourism revenue, according to a new study. Researchers looked at visitor and elephant data across 25 countries, and modeled financial losses from fewer visitors in protected areas due to the illegal wildlife trade, which has caused elephant numbers to plummet by more than 100,000 in the last decade. (A)

The study team combined visitor numbers across 164 protected areas in 25 countries in forest and savannah elephants, and elephant population data from 2009 to 2013, to reach a “per elephant" value in terms of tourism income.

They concluded that Africa was most likely losing $26m in tourism revenue a year. (B) Around $9m of that is lost from tourists' direct spending, such as staying at hotels and buying crafts, with the rest through indirect value in the economy such as farmers and other suppliers supporting the tourist industry.

The study, published in the journal Nature Communications, found that in most cases the revenue losses were higher than paying for stronger anti-poaching measures to keep elephant populations stable. (C) Dr. Robin Naidoo, the paper's lead author and , senior conservation wildlife scientist at WWF and his team found. In the case of central Africa's forest elephants, which are harder for tourists to see and therefore attract fewer visitors, the costs of protecting them exceed the benefits from tourism. Demand from south-east Asia has seen the price of ivory triple since 2009 and it is estimated that one elephant is killed every 15 minutes. (D) Corruption, a lack of resources, and, most importantly, increasingly sophisticated poachers have hamstrung African countries' efforts to stem the trade.

Naidoo said that the research was not suggesting economic issues should be the only consideration when protecting elephants, but framing the poaching crisis as a financial one could motivate African governments and communities.

“It gives an additional reason for some groups of people, who may not necessarily be motivated by intrinsic reasons for conversation, to engage with biodiversity conservation. It makes it clear to them that it's not just in the best interests of the world to conserve this stuff, but tangible reasons for a whole different group," he said.

The word motivate in paragraph 5 is closest in meaning to ____.

We’re all born with a passion for learning that for many of us sadly fades over time. A mindset of continuous learning best positions us for an ever-evolving future. Dr. Carol Dweck, a psychologist and Stanford professor, distinguishes between a fixed mindset and a growth mindset. In a fixed mindset, people believe that their basic qualities, like intelligence or talent, are fixed traits. They believe that talent alone, without effort, creates success. They believe that they are “smart” or “dumb” and that there is no way to change. No matter how hard they work at something, a ceiling prevents them from getting better. In a growth mindset, people believe that their basic abilities can be developed through dedication and hard work. Brains and talent are a starting point. This view creates a love of learning and a resilience that is essential for great accomplishments. The sky is the limit. It’s not about proving yourself, it’s about improving yourself. “Future Shock” author Alvin Toffler once said, “The illiterate of the 21st century will not be those who cannot read and write, but those who cannot learn, unlearn and relearn.” Learning and relearning can be fun. Unlearning is hard. It’s hard discarding old thinking, protocols, treatment plans, business practices and communication styles. But that hard work is necessary to progress and grow as people and professionals. Unlearning is particularly difficult for adults; kids are good at it. Our thinking becomes more rigid as we age. How difficult was it for medical professionals of the past to unlearn bloodletting, lobotomies, arsenic and mercury treatments, urine for teeth whitening, shock therapy, and heroin for children’s coughs? All were considered contemporary medicine in our great-grandparents’ day. The importance of learning, unlearning and relearning has never been more important than in today’s rapidly changing workplace
5. According to paragraph 3, which statement is correct about learning, unlearning and relearning?

Have you ever been cycling? This spring my elder brother and I left the busy city and spent a long weekend cycling in the countryside. Our average speed was only around 14 kph, but that didn’t matter. We hadn’t come to break any speed records, or to get fit and healthy. All we wanted was some fresh air and a break from schoolwork. My bike only once went more than 30 kph, and that was when I raced my brother down the only hill on our route.  We really enjoyed cycling along flat, traffic-free country paths. There was plenty of spring sunshine, but it was quite cold, especially in the morning. We didn’t mind, though - and we soon warmed up as we rode along. Our only problem was when my brakes started making a terrible noise. But I didn’t mind as it gave us an excuse to visit a cafe while a helpful bike mechanic had a look at it.  That was one of the best things about our route: every few kilometres there was a village where we could find everything we needed. All the local people were really friendly, too. However, most places we stopped at served chips with the meals, which soon got fairly boring. One night we were woken at 4 a.m. by a group of rugby fans singing loudly in the hotel corridor. We were tired and bad-tempered when we set off the next morning and very nearly got lost, but soon felt more cheerful when the sun came out. That’s what I like about cycling - it’s simple and it’s fun. If you’re looking for a short break that’s active and cheap, then cycling is a great choice!

Light, litter and noise from boating and water sports are all major stressors on marine  life, a new study aims to enhance our knowledge of the effects of these stressors. Researchers will be gathering data from sporting events, leisure boating, tourism and beach activities. The project will assess the impact that these activities have on the environment and marine life in order to offer further guidance to organisers and water sports enthusiasts.  Mike Laflin said: “I’ve worked in the sports industry for 30 years, providing market intelligence and information services and a few years ago I started to measure the impact of sporting events on host cities and nations. I’m excited to support this new research so that we can understand more about how our activities impact the environment and how we can mitigate against any negative effects.” Theresa Laflin said: “We are very excited to be able to support all the wonderful work that the university is doing in the area of marine research, and for increasing our awareness of the detrimental impact we have on our environment.”  The PhD project will be supervised by Tamara Galloway, Professor of Ecotoxicology at Exeter, who conducts research into the human health effects of pollutants, particularly micro-plastics in water; and Steve Simpson, Associate Professor in Marine Biology and Global Change at the University of Exeter, who has shown that man-made noise is having a detrimental effect on the marine world. Simpson said: “Noise from offshore construction, shipping and motorboats all change the ocean soundscape, disrupting acoustic communication, robbing animals of fundamental sensory information and causing stress. However, working with industry we have found that by managing when and where noise is made, and developing new technology to reduce the noise, we can mitigate the impacts of noise. Finding solutions to reduce the impacts of sporting activities will further help to protect the marine environment.” Galloway said: “We’ll be looking at all forms of pollution both from everyday leisure activities and major sporting events. Investigating specific events gives us the opportunity to measure environmental quality before and after the event, and to return after a period of time to assess recovery. Such an event could be seen as an ‘acute stressor’. Then we’ll also assess ongoing sporting activities, akin to a ‘chronic stressor’ and will try to compare and contrast different types of impact.”

Read the following passage and choose the best answer (A, B, C, D):
An individual’s personality is the complex of mental characteristics that makes them unique from other people. It includes all of the patterns of thought and emotions that cause us to do and say things in particular ways. At a basic level, personality is expressed through our temperament or emotional tone. However, personality also colors our values, beliefs, and expectations. There are many potential factors that are involved in shaping a personality. These factors are usually seen as coming from heredity and the environment. Research by psychologists over the last several decades has increasingly pointed to hereditary factors being more important, especially for basic personality traits such as emotional tone. However, the acquisition of values, beliefs, and expectations seem to be due more to socialization and unique experiences, especially during childhood. Some hereditary factors that contribute to personality development do so as a result of interactions with the particular social environment in which people live. For instance, your genetically inherited physical and mental capabilities have an impact on how others see you and, subsequently, how you see yourself. Likewise, your health and physical appearance are likely to be very important in your personality development. You may be frail or robust. You may have a learning disability. You may be slender in a culture that considers obesity attractive or vice versa. These largely hereditary factors are likely to cause you to feel that you are nice-looking, ugly, or just adequate. Likewise, skin color, gender, and sexual orientation are likely to have a major impact on how you perceive yourself. Whether you are accepted by others as being normal or abnormal can lead you to think and act in a socially acceptable or marginal and even deviant way. There are many potential environmental influences that help to shape personality. Child rearing practices are especially critical. In the dominant culture of North America, children are usually raised in ways that encourage them to become self-reliant and independent. Children are often allowed to act somewhat like equals to their parents. Children are given allowances and small jobs around the house to teach them how to be responsible for themselves. In contrast, children in China are usually encouraged to think and act as a member of their family and to suppress their own wishes when they are in conflict with the needs of the family. Independence and self-reliance are viewed as an indication of family failure and are discouraged.

Business dealings are becoming more and more commonplace in Vietnam, as the  country’s economy is expanding at an unprecedented rate. In order to gain the respect and favour of any prospective business partners in the country, it is important to familiarise yourself with practices and etiquette that are integral to successful commerce. Doing so will communicate not only your familiarity with their way of life, but also your suitability as a partner and will underline your business acumen.  Regarding business meeting, the first meeting should not discuss business and should be seen only as an opportunity to get to know your counterpart and cultivate a good working relationship with them. While placing hands together and bowing your head is the traditional form of greeting in Vietnam, it has been all but eradicated by the westernisation of society. As a result, you should always shake the hand of a person you are meeting for the first time - especially if they are of the same sex. When meeting a female, you should wait for her to extend her hand first; if she does not, simply nod your head. Follow your new colleague’s lead in all matters. If they shake with both hands (left hand placed upon top of right), do the same.  The next important point is that the exchange of business cards is an important ritual in Vietnamese culture. Because of this, always make sure you bring a business card to exchange at any meeting, no matter how small or trivial it may seem. Ideally, this will be printed in both English and Vietnamese and you should always offer it using both hands. When receiving a card from someone else, accept it with both hands and study it thoroughly before putting it away to show respect. The translation of all documents into Vietnamese will demonstrate your regard for your prospective partners and your preparation in the business world.  
4. Which of the following aspects is NOT mentioned in the passage?

Read the following passage and choose the best answer (A, B, C, D):
During droughts water is scarce but is it possible to make it rain to provide water. Experiments in cloud seeding suggest that it may be possible to artificially create rainfall. Rainfall occurs when supercooled droplets of water – those that are still liquid but are at a temperature below the usual freezing point of zero centigrade – form ice crystals. Now too heavy to remain suspended in the air, these then fall, often melting on their way down to form rain. Even in dry areas the air usually contains some water. This can be made to come together and form ice crystals by seeding the atmosphere with chemicals such as silver iodide or dry ice. They work to promote rainfall by inducing nucleation – what little water is in the air condenses around the newly introduced particles and crystallises to form ice. The ‘seeds’ can be delivered by plane or simply by spraying from the ground. But does it work? It’s hard to tell for sure. As is often the case with weather and climate, it’s impossible to carry out a controlled experiment – so, in areas of increased precipitation, we can’t know whether it would still have rained even if the clouds hadn’t been seeded. Success has been claimed for trials in Australia, France, Spain and the US. In the United Arab Emirates, the technique is credited with the creation of 52 storms in the Abu Dhabi desert, while China boasts of having used the technology in reverse to keep the Beijing Olympic Games of 2008 dry. Recent research, however, suggests that it’s not as effective as was previously believed
