Across the panel, there was a consensus that the younger generations are not engaging with print media to the same extent, or in the same ways as previous generations. According to Stefan Uhl, young people continue to view print media as something “old fashioned” and if brands want to ensure their survival, they must go where the customers are and introduce an omnichannel approach. Gerhard Louw, head of global media at Deutsche Telekom echoed this sentiment by saying that if the draw of print media is “attractiveness and relevance then I think everything is happening in video. We’re talking about video and movement in everything, and if there’s a problem with print it’s that it doesn’t have that…we are being led down a path where all the excitement, all the action is going there and that’s a big problem for print.” However, as managing director of Carat Germany, Stefan Uhl suggested that this was leading to a situation of neglect for print media and that its possibilities are not being adequately explored: “[print media] has to fit to a brand’s communications target, but there are some instances where print can deliver better than any other channel. “To me, print is a one screen channel – meaning high impact - and it’s one of the very few channels left that I’m hoping somebody will focus on. I just haven’t seen an initiative talking about that strength from the print industry.” The real question, however, remains is whether we can re-introduce this medium to the younger generations, and teach them how to use print again, said Rob McIntosh, executive principle at Eight Inc and the former chief brand officer at Esprit. “And will that be successful?” he asked.

Children’s behaviour has worsened over the past five years, according to a survey of  teachers which found that a fifth thought girls were more likely to cause trouble than boys. The survey, published after teachers at a Lancashire school went on strike over discipline, found low-level disruption, including chatting and “horsing around”, was the biggest problem. Boys were more likely to be physically aggressive while girls tended to ostracise other pupils. The behaviour of boys was more of a challenge than that of girls but the actions of each sex had deteriorated, according to 56.5% of staff surveyed by the Association of Teachers and Lecturers (ATL).  Among male pupils the most challenging behaviour for teachers was physical aggression, such as pushing, spitting, kicking and hitting. A secondary teacher quoted in the survey said boys were usually aggressive with other pupils, while girls tended to call one another names. Teachers criticised a lack of role models in the home. A primary teacher said: “The boys are far more willing to be aggressive to adults, verbally and even physically. There don’t seem to be any parental boundaries set of what is an appropriate way to speak and deal with another adult.” Teachers at Darwen Vale high school, Lancashire, walked out over unruly pupil behaviour this month. They said children challenged them to fights and threatened to film lessons and post them online. The survey of more than 850 teachers, heads and other school staff found that more than 21% thought girls’ behaviour was more challenging than boys, compared with 68% who said male pupils caused more trouble. In schools that have excluded pupils, 57% said more boys and 5% said more girls had been excluded. A department head in a primary school told the survey, carried out in March, that “classes with a majority of boys tend to be louder, less co-operative and harder to teach”. Nearly half of the staff surveyed said boys’ bravado was behind their disruption. For girls, the most likely trigger was a break-up between friends. A primary school teacher from Bedfordshire said: "Boys are generally more physical and their behaviour is more noticeable. Girls often say nasty things, which end up disrupting the lesson just as much as the boys, as other children get upset and can’t focus on their work. They are usually the ones who refuse to comply with instructions." Some staff had noticed girls’ behaviour worsening.” A teaching assistant from Weston-super-Mare said: “Girls are definitely getting more violent, with gangs of girls in school who are getting worse than the gangs of boys.” The ATL annual conference in Liverpool on Monday is due to debate a motion expressing concern at increasing numbers of girls being excluded from secondary school.  Government figures for 2008-9 showed that boys represented 78% of the total number of permanent exclusions from schools in England. This proportion was unchanged from the year before. The ATL general secretary, Mary Bousted, said: "Staff get ground down daily by the chatting and messing around, which disrupts lessons for other pupils and takes the pleasure out of teaching. Even more worrying is the physical aggression, most often among boys but also among some girls, which puts other pupils and staff at risk. Schools need to have firm and consistent discipline policies and work with parents to keep schools and colleges safe places for pupils and staff alike." The education bill, now going through the Commons, will give teachers the right to search pupils for banned items and will remove the requirement to give parents a day’s notice of detention. The education secretary, Michael Gove, said the measures in the bill would “restore discipline” in the classroom.

Urban development is having a direct impact on the weather in (1) ______ cities worldwide. It has been noticed that the difference in temperature is usually greater at night and the phenomenon occurs in both winter and summer. Experts agree that this is due to urban development, when open green spaces are replaced with asphalt roads and tall brick or concrete buildings. These materials retain heat generated by the Sun and release it through the night. In Atlanta, in the US, this has even led to thunderstorms (22) ______ occur in the morning rather than, as is more common, in the afternoon. Large cities around the world are adopting strategies to combat this issue, (3) ______ it is not uncommon to find plants growing on top of roofs or down the walls of large buildings. In Singapore, the government has (4) ______ to transform it into a "city within a garden" and, in 2006, they held an international competition calling for entries to develop a master plan to help bring this about.

They also contain solar panels used to light the trees at night and also containers to collect rainwater, making them truly self-sufficient

Read the following passage and choose the best answer (A, B, C, D):
Automated manufacture arose out of the intimate relationship of such economic forces and technical innovations as the division of labor, power transfer and the mechanization of the factory, and the development of transfer machines and feedback systems as explained below. The division of labor (that is, the reduction of a manufacturing or service process into its smallest independent steps) developed in the latter half of the 18th century and was first discussed by the Scottish economist Adam Smith in his book An Inquiry into the Nature and Causes of the Wealth of Nations (1776). In manufacturing, the division of labor results in increased production and a reduction in the level of skills required of workers. Mechanization was the next step necessary in the development of automation. The simplification of work made possible by the division of labor also made it possible to design and build machines that duplicated the motions of the worker. As the technology of power transfer evolved, these specialized machines were motorized and their production efficiency was improved. The development of power technology also gave rise to the factory system of production, because all workers and machines had to be located near the power source. The transfer machine is a device used to move a workpiece from one specialized machine tool to another, in such a manner as to properly position the workpiece for the next machining operation. Industrial robots, originally designed only to perform simple tasks in environments dangerous to human workers, are now extremely dexterous and are being used to transfer, handle, and index (that is, to position) both light and heavy workpieces, thus performing all the functions of a transfer machine. In actual practice, a number of separate machines are integrated into what may be thought of as one large machine. In the 1920s the auto industry combined these concepts into an integrated system of production. The goal of this assembly-line system was to make automobiles available to people who previously could not afford them. This method of production was adopted by most automobile manufacturers and rapidly became known as Detroit automation. Despite more recent advances, it is this system of production that most people think of as automation.

Andrew Jackson Beard lived an extraordinary life for a black American inventor. Unlike the vast majority of inventors who never profit from their patents, he profited from his inventions. Andrew Beard was born a slave on a plantation in Woodland, Alabama, in 1849, shortly before slavery ended. He received emancipation at age 15 and he married at age 16. Andrew Beard was a farmer, carpenter, blacksmith, a railroad worker, a businessman and finally an inventor. He grew apples as a farmer near Birmingham, Alabama for five years before he built and operated a flour mill in Hardwicks, Alabama. His work in agriculture led to tinkering with improvement for plows. In 1881, he patented his first invention, an improvement to the double plow, and sold the patent rights for $4,000 in 1884. His design allowed for the distance between the plow plates to be adjusted. That amount of money would be the equivalent of almost $100,000 today. In 1887, Andrew Beard patented a second plow and sold it for $5,200. This patent was for a design that allowed the pitch of the blades of plows or cultivators to be adjusted. The amount he received would be the equivalent of about $130,000 today. In 1897, Andrew Beard patented an improvement to railroad car couplers. His improvement came to be called the Jenny Coupler. It was one of many that aimed to improve the knuckle coupler patented by Eli Janney in 1873 (patent US138405). The knuckle coupler did the dangerous job of hooking railroad cars together, which formerly was done by manually placing a pin in a link between the two cars. Beard, himself had lost a leg in a car coupling accident. As an ex-railroad worker, Andrew Beard had the right idea that probably saved countless lives and limbs. Beard received three patents for automatic car couplers. These are US594059 granted November 23, 1897, US624901 granted May 16, 1899, and US807430 granted on May 16, 1904. While there were thousands of patents filed at the time for car couplers, Andrew Beard received $50,000 for the patent rights to his Jenny coupler. This would be just shy of 1.5 million dollars today. Congress enacted the Federal Safety Appliance Act at that time to enforce using automatic couplers. Andrew Jackson Beard was inducted into the National
Inventors Hall of Fame in 2006 in recognition of his revolutionary Jenny coupler

Read the following passage and choose the best answer (A, B, C, D):
Globalization can be seen as increased economic, cultural and technological exchange between countries. Examples might be McDonald's in Calcutta and Japanese motor technology in Britain. Many international organizations are pro-globalization, while many others are anti- ones. The main organizations against globalization are the environmental organizations, such as Friends of the Earth and reenpeace, who put forward the belief that globalization harms the environment. In general, these organizations blame global corporations for global warning and the depletion of natural resources. The most obvious is oil and gas, but there are others such as tropical rainforests, which are cut down for timber, and the resources of the sea, which may be affected by pollution. Organizations which represent developing countries, including international aid agencies such as Oxfam, are also against globalization. They are concerned that the global organizations, such as the International Monetary Fund (IMF) and the World Bank, are not doing enough to help the poor and indeed, may be adding to their problems. Some are critical of the World Trade Organization (WTO). They argue that the WTO is making difficult for poor countries to protect and build their own industries. On the contrary, many organizations are in favor of globalization. Perhaps the most important one is the WTO. This organization was set up in 1995 and has 123 member countries. It administers the rules of international trade agreed by its member countries. The WTO's rules make it difficult for a country to favor their own industry over imports from other countries. The WTO argues that the growth of trade between countries increases the wealth of everyone. Trade allows those who can produce goods most cheaply to do so, thus giving everyone the best possible price. Another pro-globalization organization is IMF. This was established after World War II in 1946. It aims to promote international cooperation on finance and provide temporary help for countries suffering financial problems. The IMF has 182 member countries. Finally, the United Nations, which was established after the Second World War, has become a promoter of globalization. It aims to  promote a shared set of values in the areas of labour standards, human rights and environmental practices between the UN and the business community.

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

Adharanand Finn is a British journalist and a keen runner. Recently, he did the Fluorspar run in Kenya with a group of top Kenyan athletes. Here is the story he told the press after the event. The route of the Fluorspar run is exactly 21 km long and is uphill from start to finish. When I arrived at the start of the run at the bottom of the hill, the morning sun was up, and it was already hot. The ten athletes and I stood together for a group photograph and then immediately started our run up to the top. Most of the athletes who live in this part of Kenya have done it at least once. After about five minutes, I was already starting to fall behind other runners. I’ve never been that good at hill climbing, so I always knew I’d find it thorny. ‘Sure and steady,’ I told myself as I ran along, avoiding the biggest stones and trying to take the shortest line up the hill. But whenever I looked up, the others were further ahead, until soon they disappeared completely. At first I felt fine, but towards the end I began to feel a bit weak and strange. I don’t know now if I was imagining things but the people I passed, who were travelling down the road, seemed to be laughing at me. Finally, I reached the top. The rest of the runners were sitting on the grass, drinking lemonade and eating peanuts and boiled eggs. It took me one hour and fifty eight minutes, which is not bad at all. The others told me kindly that anyone who can run it in under two hours is very strong. They completed it much faster, in around one hour 30 minutes. I honestly have no idea how they do it.

Read the following passage and choose the best answer (A, B, C, D):
Traditional media come from the people and antecede the mass media; their appeal has historically been both functional and aesthetic. Whether of roughly hewn folk origins or of classifically rigid moulds, they have always served to entertain, educate to reinforce existing ideas or ideologies or to change existing values and attitudes. In other words, it is a means of changing values, attitudes and norms in order to provide a proper climate for social and economic progress. It is also a method of promoting certain behavioural acts or patterns. The aim is to get people to perform specific acts to achieve objectives of national policy (e.g. visiting clinics, investing in bonds, using fertilizer). Moreover, it is a channel for conveying information about available techniques and facilities which people may use to solve problems. Being close to people at the local level, these channels are potentially useful in the service of social concerns, as determined by local, provincial or national authorities themselves. They are, moreover, abundantly present in areas where mass media technology has not been fully or effectively developed to capture sustained interest at local, provincial or national levels. Folk media are personal forms of entertainment and communication. This is important because behavioural changes are most easily brought about by personal interaction. These forms of art are a part of the way of life of a community and provide acceptable means of bringing development issues into the community in its own-terms. They are capable of reaching intimate social groups, thus making use of already established communication networks in the audience.

The weather is a national obsession in Britain, perhaps because it is so changeable. It's the national talking point, and most people watch at least one daily weather forecast. Most of the viewers imagine that the presenter does little more than arrive at the studio a few minutes before the broadcast, read the weather, and then go home.
In fact, this image is far from the truth. The two-minute bulletin which we all rely on when we need to know tomorrow's weather is the result of a hard day's work by the presenter, who is actually a highly-qualified meteorologist.
Every morning, after a weather forecaster arrives at the TV studios, his/her first task of the day is to collect the latest data from the National Meteorological Office. The information is very detailed and includes predictions, satellite and radar pictures, as well as more technical data. After gathering all the relevant material from this office, the forecaster has to translate the scientific terminology and maps into images and words which viewers can easily understand. The final broadcast is then carefully planned. The presenter decides what to say and in what order to say it. Next a “story board” is drawn up which lays out the script word for word.
The time allocated for each broadcast can also alter. This is because the weather report is screened after the news, which can vary in length. The weather forecaster doesn't always know how much time is available, which means that he/she has to be thoroughly prepared so that the material can be adapted to the time available.
What makes weather forecasting more complicated is that it has to be a live broadcast and cannot be pre-recorded. Live shows are very nerve-racking for the presenter because almost anything can go wrong. Perhaps the most worrying aspect for every weather forecaster is getting the following day's predictions wrong. Unfortunately for them, this is not an unusual occurrence; the weather is not always possible to predict accurately.
These days, a weather forecaster's job is even more complicated because they are relied upon to predict other environmental conditions. For example, in the summer the weather forecast has to include the pollen count for hay fever sufferers. Some also include reports on ultraviolet radiation intensity to help people avoid sunburn. The job of a weather forecaster is certainly far more sophisticated than just pointing at a map and describing weather conditions. It's a job for professionals who can cope with stressful and challenging conditions.

Even though it’s sometimes hard for parents to think about letting go of their child, the best relationships are the ones that teens come back to, as adults, recognizing how their parents have helped them into adulthood by not clinging or pushing them away too soon. We recommend that parents look for opportunities to teach independence, starting in childhood. Encourage your teen to be responsible for his or her own time. “How much time do you need for homework?” “How long to do you need to unwind after school?” If the answers to these questions are “None” and “Until midnight”, then your teen needs some help making a schedule. Many teens can come up with a reasonable time for getting things done, with some practice and initial limits from you. You may want to let her try out her schedule through, say, one grading period. If grades go down, the schedule needs work and maybe more supervision from you. Not knowing basic financial skills can be one the first things to trip up a newly independent young adult. Look for chances to teach basic money skills. Some parents give their teen a set amount of money and let her plan the weekly grocery shopping or family vacation. Have her help you pay utility bills and budget for expenses. Explain carefully about credit cards and limit access to credit. Teens are impulsive, and easily get stuck in the trap of  charging more than they can pay off. An after-school job is a great opportunity for your teen to start practicing. More than anything else, teens learn from making mistakes. As a parent, your job is to try to make sure that the mistakes your teen makes aren’t life-threatening, like getting into the car with a drunk driver. Most mistakes, though, will not fall into that category. No one is perfect, especially parents. It’s important that teen see that you do not expect perfection from him or from yourself, and that you can admit your mistakes when you make them. Letting your teen make mistakes, and letting him suffer the consequences of a mistake, can be hard to do. But when you give your teen permission to make mistakes, and let him know you love him anyway, you tell him that you believe in his ability to take a fall, get up and learn from it

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.

You’ll be able to purchase high-quality emotions online. Emotion-sharing experiences  are the latest fad in 2045. Imagine your friend at Glastonbury can post a photo on Instagram and with it comes bundled a faint twinkling of what she was feeling right there in that moment, so you too can share emotionally in her social experience.  Recently, techniques for direct brain stimulation, like opt genetics, have made it possible to not only read but also write information into single neurons. At the moment data transfer rates are still very slow, the best we can do is a few bits per second, but this could well increase to kilobits or maybe reach broadband speeds by 2045. This means the range of human perception could expand beyond its current design limitations. One could foresee a new and extraordinary world where there is a virtual marketplace for trading high quality emotions – where artists looking for a particularly high strength brew of melancholy, or actors needing to channel regret or compassion for their next play, could purchase emotions online.  Our cities will be made from living, dynamic materials that respond to the environment. In 30 years, tall buildings made of glass and twisted steel will be seen as relics from a bygone era, in the same way we think now of 1970s concrete tower blocks: ugly, outdated and unfit for contemporary purpose. The urban environment of 2045 blends architecture with living materials that are mouldable, adaptable, responsive and disposable.  Entirely new synthetic life forms, or biological machines, made of engineered living cells from bacteria, fungi and algae will grow and evolve with the changing needs of a building’s inhabitants. They breathe in pollutants, clean wastewater, and use sunlight to make useful chemicals, energy, heat and vibrant vertical gardens. We will start to see a convergence between biology and technology, to the point where there is no longer a perceptible difference between the two. Today, synthetic biology labs are looking at the full diversity of what nature has to offer and using this to mix, match and edit genomes to design synthetic life forms. Right now, this field is just getting started and the science of synthetic biology is going to be tougher than most will admit.  We will use invisibility cloaks to “disappear” ugly objects. Invisibility has forever been a tantalizing prospect. The key to cloaking lies in the way the electromagnetic spectrum  (including visible light) interacts with objects. The human eye picks up electromagnetic radiation that falls and scatters from objects and we perceive this as light. In recent decades, scientists figured out using mathematics that it might just be possible to imagine a new class of artificial materials made of intricate tiny features with light bending properties. They named them metamaterials.  Using nanotechnology engineering, scientists have since shown cloaking actually works – in principle at least, for a narrow range of colours and only from certain viewing angles. The future applications of cloaking are highly uncertain and will likely be determined by the fads and social contagion of the time. They may be used in everything from novelty gimmicks to making unsightly construction sites and power stations seemingly ‘disappear’.
