The dramatic growth of the world's population in the twentieth century was on a scale without parallel in human history. Most of this growth had occurred since 1950 and was known as the population 'explosion'. Between 1950 and 1980 the world population increased from 2.5 to over 4 billion, and by the end of the twenty century the figure had risen to about 6.6 billion. Growth of this size cannot continue indefinitely. Recent forecasts suggest that the total population will level out at between 10 and 15 billion in the mid twenty first century. Already there are encouraging signs that the rate of increase in many less developed countries is beginning to slow down.

It has been forecast that, by the middle of the twenty-first century _____.

If you go back far enough, everything lived in the sea. At various points in evolutionary history, enterprising individuals within many different animal groups moved out onto the land, sometimes even to the most parched deserts, taking their own private seawater with them in blood and cellular fluids. In addition to the reptiles, birds, mammals and insects which we see all around us, other groups that have succeeded out of water include scorpions, snails, crustaceans such as woodlice and land crabs, millipedes and centipedes, spiders and various worms. And we mustn’t forget the plants, without whose prior invasion of the land, none of the other migrations could have happened. Moving from water to land involved a major redesign of every aspect of life, including breathing and reproduction. Nevertheless, a good number of thoroughgoing land animals later turned around, abandoned their hard-earned terrestrial re-tooling, and returned to the water again. Seals have only gone part way back. They show us what the intermediates might have been like, on the way to extreme cases such as whales and dugongs. Whales (including the small whales we call dolphins) and dugongs, with their close cousins, the manatees, ceased to be land creatures altogether and reverted to the full marine habits of their remote ancestors. They don’t even come ashore to breed. They do, however, still breathe air, having never developed anything equivalent to the gills of their earlier marine incarnation. Turtles went back to the sea a very long time ago and, like all vertebrate returnees to the water, they breathe air. However, they are, in one respect, less fully given back to the water than whales or dugongs, for turtles still lay their eggs on beaches. There is evidence that all modern turtles are descended from a terrestrial ancestor which lived before most of the dinosaurs. There are two key fossils called Proganochelys quenstedti and Palaeochersis talampayensis dating from early dinosaur times, which appear to be close to the ancestry of all modern turtles and tortoise. You might wonder how we can tell whether fossil animals lived in land or in water, especially if only fragments are found. Sometimes it’s obvious. Ichthyosaurs were reptilian contemporaries of he dinosaurs, with
fins and streamlined bodies. The fossils look like dolphins and they surely lived like dolphins, in the water. With turtles it is a little less obvious. One way to tell is by measuring the bones of their forelimbs.

Mohammed BK, who aims to connect Somalis in Bristol with their heritage, has been  confirmed for the Somali Week Festival, in 2020. Mohammed BK has been named as “cultural ambassador” for the Somali community. Ayan Mohamoud who is UK’s Somaliland Ambassador told the BBC he will now become a fixed part of the annual festivities. She said: “Young people who don’t speak Somali at all have memorised his music word-for-word and that is something that has never been done before by any Somali artist. He has been touring the country promoting citizenship and cultural unity throughout his career.”  Susan Elmi, 25, has been a fan of Mohammed BK for many years. She said: "In the Somali culture many people communicated their emotions and thoughts through songs and poetry and this is going back centuries. This man is bringing that back and making the younger generation question and explore our rich legacy. I think it’s just what the Somali Diaspora needs to say well connected to the identity.”  Mohammed BK also promotes education and advises young people to “use their time and resources wisely here in the UK because that is something their parents sacrificed fleeing from their homeland”. He added: “I thought to myself if I have that much influence on thousands and thousands of young people from my community, I need to put my platform to good use in encouraging them to do good and seek opportunities”. Festival fan Ameira Hassan, 45, said: “It’s a huge thing for our kids to take part in their history and culture. It’s important to us because they are learning a lot. Twenty years ago we never used to have anything like this in the UK and our kids never had any knowledge of the Somali culture.”

Read the following passage and choose the best answer (A, B, C, D):
In the past, technology and progress was very slow. People “invented” farming 12,000 years ago but it took 8,000 years for the idea to go around the world. Then, about 3,500 years ago, people called “potters” used round wheels to turn and make plates. But it took hundreds of years before some clever person thought, if we join two wheels together and make them bigger, we can use them to move things. In the last few centuries, things have begun to move faster. Take a 20th-century invention like the aeroplane, for example. The first aeroplane flight on 17 December 1903 only lasted 12 seconds, and the plane only went 37 metres. It can’t have been very exciting to watch, but that flight changed the world. Sixteen years later, the first plane flew across the Atlantic, and only fifty years after that, men walked on the moon. Technology is now changing our world faster and faster. So what will the future bring? One of the first changes will be the materials we use. Scientists have just invented an amazing new material called grapheme, and soon we will use it to do lots of things. With grapheme batteries in your mobile, it will take a few seconds to charge your phone or download a thousand gigabytes of information! Today, we make most products in factories, but in the future, scientists will invent living materials. Then we won’t make things like cars and furniture in factories - we will grow them! Thirty years ago, people couldn’t have imagined social media like Twitter and Facebook. Now we can’t live without them. But this is only the start. Right now, scientists are putting microchips in some disabled people’s brains, to help them see, hear and communicate better. In the future, we may all use these technologies. We won’t need smartphones to use social media or search the internet because the internet will be in our heads! More people will go into space in the future, too. Space tourism has already begun, and a hundred years from now, there may be many hotels in space. One day, we may get most of our energy from space too. In 1941, the writer Isaac Asimov wrote about a solar power station in space. People laughed at his idea then, but we should have listened to him. Today, many people are trying to develop a space solar power station. After all, the sun always shines above the clouds!

Where smart cities were once regarded purely as a vision of the future, they are now  becoming a reality in numerous urban centres across the globe. From Dubai, Singapore, Amsterdam, Copenhagen, and Madrid to Southampton in the UK, we’re already beginning to see smart cities provide inhabitants with improved living conditions, easier mobility and cleaner, safer environments, by using cloud computing to power services. But as with all public sector initiatives, smart city services need to be delivered as cost effectively as possible to minimise the taxpayer burden. Often, key decision makers are met with obstacles when it comes to deploying smart services, preventing smart cities initiatives from reaching their full potential – or worse, blocking them altogether.  Central to the functioning of most ‘normal’ city ecosystems is the underlying data they run on. Regardless as to whether that data is stored on local servers or using cloud storage, when that data is fragmented or incomplete, identifying emerging trends for strategic planning and cost reduction becomes extremely difficult – and because of this, authorities have to adopt an entirely reactive approach. Conversely, in a smart city environment, connected sensors forming an Internet of Things (IoT) provide valuable data for analysis and, in turn, insight into the specific city’s behavioural trends. With this level of information, services can be optimised to reduce costs and risk, increase urban flows and manage assets. Importantly, they can also provide real-time connections and interactions between the city’s businesses, local governments, service providers and citizens.  In this way, operations and services are elevated through the integration and connection of physical devices via IoT networks, ultimately transforming how a city runs.

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

Read the following passage and choose the best answer (A, B, C, D):
While light at night can be beneficial, neutral, or damaging for individual species, its presence invariably disturbs ecosystems. For example, some species of spiders avoid lit areas, while other species are happy to build their spider web directly on a lamp post. Since lamp posts attract many flying insects, the spiders that don’t mind light gain an advantage over the spiders that avoid it. Light pollution poses a serious threat in particular to nocturnal wildlife, having negative impacts on plant and animal physiology. It can confuse animal navigation, alter competitive interactions, change predator-prey relations, and cause physiological harm. The rhythm of life is orchestrated by the natural patterns of light and dark, so disruption to these patterns impacts the ecological dynamics. Studies suggest that light pollution around lakes prevents zooplankton, such as Daphnia, from eating surface algae, causing algal blooms that can kill off the lakes’ plants and lower water quality. Light pollution may also affect ecosystems in other ways. For example, scientists have documented that night time light may interfere with the ability of moths and other nocturnal insects to navigate. Night-blooming flowers that depend on moths for pollination may be affected by night lighting, as there is no replacement pollinator that would not be affected by the artificial light. This can lead to species decline of plants that are unable to reproduce, and change an area’s long term ecology. Reducing light pollution implies many things, such as reducing sky glow, reducing glare, reducing light trespass, and reducing clutter. The method for best reducing light pollution, therefore, depends on exactly what the problem is in any given instance. Adjusting the type of lights used, so that the light waves emitted are those that are likely to cause severe light pollution problems

As places transformed, so did the people. When researchers at Yale University and the University of Westminster studied what images people associated with climate change, they found a shift this decade. When they began their study in 2003, the majority of people surveyed thought of melting polar ice. By 2016, more and more people had weather top of mind. Climate, to be clear, is not weather. It’s the difference between a trend and a one-off event. But with wetter storms and hotter summers unfolding over the course of the decade, people were making new connections between climate change and the weather. Seeing climate change through the lens of something they experience every day opens the door for people to see the weight of the issue over their own lives. “Americans are just beginning to connect the dots and to say, wait a second, what’s going on here,” says Anthony Leiserowitz, a lead author of the study and director of the Yale Program on Climate Change Communication. “There’s been this increasing dawning of awareness among many Americans that climate change is actually starting to harm people here and now.” New renewable energy projects outpaced new fossil fuel installations in worldwide growth for the first time in 2015. In a pivotal moment for the whole planet, every country on Earth agreed to take on climate change when they adopted the Paris climate accord in 2015. That committed countries to reducing their greenhouse gas emissions enough to keep the Earth from warming beyond roughly 1.5 degrees Celsius above pre-industrial levels, a threshold that could be catastrophic for people and ecosystems if it’s crossed. It was the culmination of years of political wrangling. “It is rare to have the opportunity in a lifetime to change the world,” former French president François Hollande told delegates gathered on the final day of negotiations. “Seize it so that the planet can live on, so that humanity can live on.” But cooperation, even when the health of the whole planet is on the line, can be a fragile, fleeting thing. After Donald Trump was elected president in 2016, he began the process of formally withdrawing the US from the Paris accord. One by one, Trump backtracked on existing federal efforts to cut down on pollution, too. The words “climate change” began disappearing from government websites and documents

The World Health Organization on Wednesday declared the rapidly spreading  coronavirus outbreak a pandemic. Director-General Tedros Adhanom Ghebreyesus said that “We expect to see the number of cases, the number of deaths, and the number of affected countries climb even higher.”  WHO officials had said earlier they were hesitant to call the outbreak a pandemic in case it led governments and individuals to give up the fight. On Wednesday, they stressed that fundamental public health interventions can still limit the spread of the virus and drive down cases even where it was transmitting widely, as the work of authorities and communities in China, Singapore, and South Korea has shown.  The virus, which probably originated in bats but passed to people via an as yet unrecognized intermediary animal species, is believed to have started infecting people in Wuhan, China, in late November or early December. Since then the virus has raced around the globe. South Korea, which has reported nearly 8,000 cases, also appears poised to bring its outbreak under control with aggressive measures and widespread testing. But other countries have struggled to follow the leads of China and South Korea — a reality that has frustrated WHO officials who have exhorted the world to do everything possible to end transmission of the virus. Tedros used the fact that 90% of the cumulative cases have been reported in just four countries as evidence that the rest of the world still had time to prevent an explosion of cases with action.  WHO officials also stressed that countries should be implementing a strategic combination two types of measures. One involves trying to detect and stop known chains of transmission by isolating cases and following and potentially quarantining their contacts. The other involves community-level steps like social distancing and comes into play when the virus is spreading more broadly and transmission chains can’t be tracked. Mike Ryan, the head of the WHO’s emergency program, said that the public health interventions might not have straightforward effect, but to slow the spread of the virus. People with severe cases can require long periods of critical care and strain the resources of hospitals. He said he was worried about “the case load, the demand on the health workers, the dangers that come with fatigue, and potentially shortages of personal protective equipment.”

If you want to spend your time effectively, you can try the following tips. First, make a to-do list every day. Put the most important tasks at the top, even if  they’re things you’re dreading, and tackle them first. Include things you want to do on your list too, so you have items you’re looking forward to. Try motivating yourself with a reward if you get to everything on your list.  Once you know what you need to do, keep your work with you. That way, if you find yourself with extra time – while in the train or bus or waiting for an appointment – you can get something done.  Additionally, don’t be afraid to say no. It’s OK to say no if your friend asks you to go to a movie one night but you have a test the next morning. Instead, find a time that works for both of you and go to see the movie then.  Managing your time also includes finding you productive time. Are you a morning person or a night person? You’ll be more efficient of you work when you’re at your best.  Last but not least, create a dedicated study time. Set up a time devoted only to studying or homework. Shut off you phone and respond to calls or texts when your work is finished. Don’t check email or surf the web (except when you need to for the work you’re doing) during this time either.

In addition to improved physical health, sport plays a primarily positive role in youth  development, including improved academic achievement, higher self-esteem, fewer behavioral problems, and better psychosocial development. Many studies focus on the effects of sport on the five “C’s” - competence, confidence, connections, character, and caring. The many facets of playing sport - the discipline of training, learning teamwork, following the leadership of coaches and captains, learning to lose - provide lifelong skills for athletes.  The literature on youth sport stresses the positive effects of participation in learning the important life skills of goal setting and time management combined with enjoyment; the development of a strong sense of morality; and the development of an appreciation of diversity. Studies have shown that children and youth participating in sport, when compared to peers who do not play sport, exhibit higher grades, expectations, and attainment; greater personal confidence and self-esteem; greater connections with school – that is, greater attachment and support from adults; stronger peer relationships, more academically oriented friends, greater family attachment and more frequent interactions with parents; more restraint in avoiding risky behavior; and greater involvement in volunteer work.  Sport provides opportunities for children and youth to engage in valuable and positive relationships with adults. Thus, it is a missed opportunity for children who are "gated" - or not included in sport - during early stages of childhood because they are less well behaved than other children. These children are being prevented from participating in the very thing that could help them learn to control and regulate their behavior. Sport provides an opportunity for children to safely navigate and negotiate between right and wrong as they learn to interact with peers and adults. Research by Taliaferro et al. suggests that playing sport can even protect against suicide risk in youth. Compared to non-athletes, male athletes exhibit lower levels of hopelessness and suicidal ideation. Young males involved in multiple sports seem to garner even more protection in this regard. Similar results were found for girls. Research on the role of exercise in adults confirms that it improves mood and alleviates many forms of depression. Bartko and Eccles les found that youth who are highly involved in sport are more “psychologically resilient,” that is, better able to recover from problems. Eccles et al. found that sport participation protects young athletes against social isolation
2. According to the passage what is NOT increased by playing sports?
