Public universities, private universities, arts colleges, and community colleges all has a significant role in higher education in the United States

Read the following passage and choose the best answer (A, B, C, D):
A (1) ______ teacher can reach thousands of students in an online course, opening up a world of knowledge to anyone with an internet connection. This limitless reach also offers substantial benefits for school districts that need to save money, by reducing the number of teachers. (2) __________, in high schools and colleges, there is mounting evidence that the growth of online education is hurting a critical group: the less proficient students (3) _______ are precisely those most in need of skilled classroom teachers. Online courses can be broken down into several categories, and some are more effective than others. In “blended” courses, for example, students don’t do their work only online: They also spend time in a classroom with a flesh-and-blood teacher. Research suggests that students — at nearly all levels of achievement — do just as well in these blended classes as they do in traditional classrooms. In this model, online resources supplement traditional instruction but don’t replace it. In the fully online model, on the other hand, a student may never be in the same room with an instructor. This category is the main problem. It is where less proficient students tend to (4) _________ trouble. After all, taking a class without a teacher requires high levels of self-motivation, self-regulation and organization. Yet, in high schools across the country, students who are struggling in (5) ________classrooms are increasingly steered into online courses

Read the following passage and choose the best answer (A, B, C, D):
College is a new and different experience for me. I’m away from home, so I have  many things to adjust to. Being on my own, talking with friendly people, and having Fridays off - these are just some things I like about college.  Living at college, first of all, gives me a sense of responsibility, of being on my own. My parents are not around to say, “No, you’re not going out tonight.” Or “Did you finish your homework?” Everything I do has to be my decision, and that gives me the responsibility of handling my own life. During the second week I was at college, I had to go out and look for a bank where I could open an account. Before that I looked in the phone book since I had no clue about any banks around here or where they were located. Someone told me to go to a bank named Continental Federal Savings. And I had to make my own decision - whether to have a checking or saving account and whether or not to get a card. I’m on my own to make my own decisions.  I also love to have Fridays off. I wouldn’t be able to deal with five days of classes in a row. I love to sleep in. One Thursday night, my roommates and I went to Georgetown. We got in rather early the next morning, and my roommates and I decided to sleep in, something I couldn’t do in high school.  I do like things about college - being on my own and having Fridays off, but this doesn’t mean I don’t think about things at home. Although I like college, I can still get homesick: New York is a pretty good place, too.

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.

In line 1, the author uses the words “human assistance” to mean .

Read the following passage and choose the best answer (A, B, C, D):
For 150 years scientists have tried to determine the solar constant, the amount of solar energy that reaches the Earth. Yet, even in the most cloud-free regions of the planet, the solar constant cannot be measured precisely. Gas molecules and dust particles in the atmosphere absorb and scatter sunlight and prevent some wavelengths of the light from ever reaching the ground. With the advent of satellites, however, scientists have finally been able to measure the Sun's output without being impeded by the Earth's atmosphere. Solar Max, a satellite from the National Aeronautics and Space Administration (NASA), has been measuring the Sun's output since February 1980. Although a malfunction in the satellite's control system limited its observation for a few years, the satellite was repaired in orbit by astronauts from the space shuttle in 1984. Max's observations indicate that the solar constant is not really constant after all. The satellite's instruments have detected frequent, small variations in the Sun's energy output, generally amounting to no more than 0.05 percent of the Sun's mean energy output and lasting from a few weeks. Scientists believe these fluctuations coincide with the appearance and disappearance of large groups of sunspots on the Sun's disk. Sunspots are relatively dark regions on the Sun's surface that have strong magnetic fields and a temperature about 2,000 degrees Fahrenheit cooler than the rest of the Sun's surface. Particularly large fluctuations in the solar constant have coincided with sightings of large sunspot group. In 1980, for example, Solar Max's instrument, registered a 0.3percent drop in the solar energy reaching the Earth. At that time a sunspot group covered about 0.6 percent of the solar disk, an area 20 times larger than the Earth's surface. Long-term variations in the solar constant are more difficult to determine. Although Solar Max's data have indicated a slow and steady decline in the Sun's output, some scientists have thought that the satellite's aging detectors might have become less sensitive over the years, thus falsely indicating a drop in the solar constant. This possibility was dismissed, however, by comparing Solar Max's observations with data from a similar instrument operating on NASA's Nimbus 7 weather satellite since 1978.
3. Why is it not possible to measure the solar constant accurately without a satellite?

Read the following passage and choose the best answer (A, B, C, D):
The era of “smart cities”, controlled by an ecosystem of sensors, cameras and  algorithms, is fast approaching. In China, state media claim 500 are under construction. In Canada, Alphabet has plans for turning parts of Toronto into a timber-framed tech town as a prototype. Incremental steps are also making cities smarter. Last week, Transport for London announced plans to track Tube passengers through WiFi to monitor congestion. In the US, fast-food drive-throughs will trial number plates scanners to make ordering faster. Individually these services can improve daily life. Integrating them will create something more powerful than the sum of its parts.  Though convenience and safety are the end goals, serious questions about how city authorities will both store and share vast bodies of data must be answered. The fact that surveillance is built into key transport infrastructure will also make it increasingly difficult to avoid without disrupting daily life. The smart city risks creating a panopticon in the name of an easier and better life. The risks of anonymity disappearing will be increased by the use of different data sets, making it more likely that identifiable characteristics may appear. Closely linked to this is the question of data storage and sharing. The treasure trove of personal information will be a tempting target for hackers. This information might also be used by law enforcement, feeding into the existing dangers of mass surveillance and profiling, as is already the case in China.  These concerns have long been levelled at social media and internet-enabled home appliances. Smart city surveillance can be even more insidious. Users can avoid Facebook or hardware such as Alexa. Avoiding basic infrastructure will be near impossible without seriously affecting day-to-day life. TfL has put up signs warning customers of the WiFi tracking, yet the only choice is between tracking and having no signal. Reports on the facial recognition at airports in America suggest that avoiding being automatically scanned will be tough as well. As these systems become more closely enmeshed, avoiding snooping will become increasingly tricky.  The inevitable rise of smart cities is not inherently negative. Harnessing the power of technology and data can potentially help urban environments adapt to challenges such as climate change and overcrowding. Politicians, programmers and academics must work to ensure that does not come at the cost of all-seeing, 24-hour surveillance.

Read the following passage and choose the best answer (A, B, C, D):
The process of communication has so importance at present moment. It has great expansion and is a necessary agent of socialization. The social communication has great power in the human species, from the origin of the history. The media of social communication can be television, radio, cinema, written or audiovisual press and highways of the information. They do, generally, universalization of the culture of the people. They extend the horizons and the limits between countries. They promote new social models, conducts and values. And they promote a dominant ideology. Often, the media of social communication are very far from the reality of the individuals. They, generally, do not perceive the habitual context of the persons. The social media complement and collaborate in the process of socialization of the new generations, from a positive opinion. Advertising and commercial messaging, pose consumerist models, from a negative perspective. The mass media convert a genuine culture into a consumer society. The advertising stimulates the need to consume, desperately. It transforms the persons into consumers of products. The advertising has a great power on the persons and it transports a serious addiction. The family, the educational system and the society, must allow the process of socialization and formation, to all people. They also must give the tools of analysis and the critique. They also must give offers of interesting things. They must promote the respect to the desires and different opinions. They also must promote the capacity of choice. The mass media influence the children and young people. They have models of identification, values, guidelines and policies. Often, they do not coincide with the own reality. They can serve to think. The mass media influence the process of social adjustment

Belgium is a very old country, with a fascinating mixture of old customs and modern  laws. Belgium weddings may be performed as a civil ceremony or as a religious ceremony. Traditionally, when a couple in Belgium wishes to announce their marriage, the  wedding invitations are printed on two sheets of paper, one from the bride’s family and one sheet from the groom’s family. These wedding invitations symbolize the union of the two families and the partnership of the new union.  An ancient Belgium custom that is designed to unite the two families calls for the bride to stop as she walks up the aisle and to hand her mother a single flower. The two then embrace. Then, during the recessional, the bride and groom walk to the groom’s mother and the new bride hands her new mother-in-law a single flower and the two of them embrace, symbolizing the bride’s acceptance of her new mother.  One of the most important and enduring traditions of the Belgium wedding is for the bride to carry a specially embroidered handkerchief that has her name embroidered on it. After the wedding this handkerchief is framed and hung on the wall in a place of honor.  When the next female member of the bride’s family is to be wed, the handkerchief is removed from its frame, the new bride’s name is embroidered onto it, and it is passed down. The wedding handkerchief is passed from generation to generation, and is considered an important family heirloom. During the wedding mass, the bride and the groom are enthroned in two large chairs placed near the altar, symbolizing that on this day and in this place they are the king and the queen. At the conclusion of the ceremony, the groom slips the wedding ring onto the third finger of his bride’s left hand. The ring, being an endless circle, symbolizes never-ending love, and the third finger of the left hand is believed to hold the vein that travels to the heart, symbolizing love. At the conclusion of the ceremony, the bride and groom share their first kiss as husband and wife. The kiss is considered a symbolic act of sharing each other’s spirit as the couple each breathes in a portion of their new mate’s soul.  The bridesmaids traditionally take up a collection of coins and as the bride and groom exit the church, the bridesmaids toss the coins to the poor outside the church. Giving gifts of money to the poor helps to insure prosperity for the new bride and groom.  Following the wedding the bride and groom are off on their honeymoon. In ancient times the honeymoon, which was celebrated by the drinking of mead, or honey wine, would last 28 days, one complete cycle of the moon. This was to make sure that the bride’s family did not try to steal their daughter back from her new husband. 
3. The following is true about Belgium’s wedding, EXCEPT ___________

Pick any day in the Piazza del Duomo in the Italian city of Pisa, and you will  undoubtedly spot a bunch of tourists posing for the same photo: hands outstretched towards the cathedral’s conspicuously tilting bell tower, as if they are supporting it with their sheer strength. The so-called Leaning Tower of Pisa is one of the most famous buildings in the world, although maybe not for the reasons its original architects would have wanted.  In 1173, construction began on a white marble bell tower for the cathedral complex in Pisa, located between the Arno and Serchio rivers in Tuscany, central Italy. By the time builders had finished the third of eight planned stories about five years later, the tower’s foundation had begun to settle unevenly on the ground beneath it, a dense mixture of clay, sand and shells. As a result, the structure had begun to tilt visibly toward the south. Shortly after that, war broke out between Pisa and Genoa, another Italian city-state, halting construction for nearly a century. This delay allowed the foundation to settle further, likely prevented the bell tower’s premature collapse.  When construction resumed, chief engineer Giovanni di Simone tried to compensate for the lean by adding extra masonry to the short side, but the additional weight caused the structure to tilt even further. The tower was officially completed around 1370, but its lean only increased over the next six centuries, becoming an integral part of the monument’s quirky appeal. Despite various attempts to reinforce it, Pisa’s tower continued to subside at a rate of some 0.05 inches per year, placing it in increasing danger of collapse. By 1990, it was leaning 5.5 degrees (or some 15 feet) from the perpendicular–the most extreme angle yet. That year, the monument was closed to visitors and the bells removed as engineers started extensive reparations to stabilize it. By siphoning earth from beneath and adding counterweights to the tower’s north end, they were able to reduce the lean to 13.5 feet, or 4.0 degrees from perpendicular. The straightening continued after the tower reopened in 2001, and in 2008 sensors showed the subsiding motion had stopped, after a total improvement of some 19 inches. Engineers now believe the Leaning Tower of Pisa will remain stable for some 200 years, barring an earthquake or other unpredictable disaster.

Read the following passage and choose the best answer (A, B, C, D)
Women’s representation in government is stalled, and in some cases moving backward. Does that make a difference to the work of governing? Yes, according to decades of data from around the world. Women govern differently than men do in some important ways. They tend to be more collaborative and bipartisan. They push for far more policies meant to support women, children, social welfare and — when they’re in executive positions — national security. But these bills are also more likely to die, largely because of gender bias, research shows. Women in Congress sponsor and co-sponsor more bills than men do, and bring 9 percent more federal money to their districts, according to a study in the American Journal of Political Science. Those bills are more likely to benefit women and children or address issues like education, health and poverty. In Congress, for instance, women fought for women’s health coverage in the Affordable Care Act, sexual harassment rules in the military, the inclusion of women in medical trials, and child care vouchers in welfare overhaul. “All members of Congress have to follow their constituency, but because of their personal experiences either as women in the work force or as mothers, they might be inclined to legislate on some of these issues,” said Michele L. Swers, a professor of government at Georgetown University who studies gender and policy making.  In a new analysis of the 151,824 public bills introduced in the House between 1973 and 2014, to be published in print in Political Science Research and Methods, researchers found that women were significantly more likely than men to sponsor bills in areas like civil rights, health and education. Men were more likely to sponsor bills in agriculture, energy and macroeconomics. An analysis of floor speeches during the 106th Congress, by political scientists at the University of Iowa and Oklahoma State University, found that women spent more time talking about policy concerns like women’s health and family issues. Another study, of State of the State speechesfrom 2006 to 2008 published in State and Local Government Review, found that female governors devoted much more attention to social welfare issues than male governors did, even after controlling for political and situational factors. Women are less likely to vote for war or the death penalty. Women’s representation in legislatures is significantly correlated with the abolition of capital punishment, according to a study of 125 countries published in July by researchers at Sul Ross State University in Texas. A higher share of female legislators correlates with less military spending and less use of force in foreign policy, even after controlling for other explanations like partisanship, according to an analysis by researchers from Texas A&M University of data from 22 established democracies from 1970 to 2000. Yet when women are in executive positions, the opposite is true: They are more hawkish than men. The researchers said that could be in part because of a need to overcome stereotypes of women as weak. Margaret Thatcher, Golda Meir and Indira Gandhi, all of whom governed in conflicts, were described as governing like men.

Read the following passage and choose the best answer (A, B, C, D):
Many AI researchers roll their eyes when seeing this headline: “Stephen Hawking warns that rise of robots may be disastrous for mankind.” And as many have lost count of how many similar articles they’ve seen. Typically, these articles suggest we should worry about robots rising up and killing us because they’ve become conscious and/or evil. On a lighter note, such articles are actually rather impressive, because they succinctly summarize the scenario that AI researchers don’t worry about. That scenario combines as many as three separate misconceptions: concern about consciousness, evil, and robots. If you drive down the road, you have a subjective experience of colors, sounds, etc. But does a self-driving car have a subjective experience? Does it feel like anything at all to be a self-driving car? Although this mystery of consciousness is interesting in its own right, it’s irrelevant to AI risk. If you get struck by a driverless car, it makes no difference to you whether it subjectively feels conscious. In the same way, what will affect us humans is what superintelligent AI does, not how it subjectively feels. The fear of machines turning evil is another red herring. The real worry isn’t malevolence, but competence. A superintelligent AI is by definition very good at attaining its goals, whatever they may be, so we need to ensure that its goals are aligned with ours. Humans don’t generally hate ants, but we’re more intelligent than they are – so if we want to build a hydroelectric dam and there’s an anthill there, too bad for the ants. The beneficial-AI movement wants to avoid placing humanity in the position of those ants In fact, the main concern of the beneficial-AI movement isn’t with robots but with intelligence itself: specifically, intelligence whose goals are misaligned with ours. To cause us trouble, such misaligned superhuman intelligence needs no robotic body, merely an internet connection – this may enable outsmarting financial markets, out-inventing human researchers, out-manipulating human leaders, and developing weapons we cannot even understand. Even if building robots were physically impossible, a super-intelligent and superwealthy AI could easily pay or manipulate many humans to unwittingly do its bidding. The robot misconception is related to the myth that machines can’t control humans. Intelligence enables control: humans control tigers not because we are stronger, but because we are smarter.  
6. According to paragraph 3, why is the possible misalignment in interests of human and AI such a problem?

Read the following passage and choose the best answer (A, B, C, D):
English teenagers are to receive compulsory cooking lessons in schools. The idea is to encourage healthy eating to fight the country’s increasing obesity rate. It’s feared that basic cooking and food preparation skills are being lost as parents turn to pre-prepared convenience foods. Cooking was once regarded as an important part of education in England – even if it was mainly aimed at girls. In recent decades cooking has progressively become a minor activity in schools. In many cases the schools themselves have given up cooking meals in kitchens in the schools. But the rising level of obesity has led to a rethink about the food that children are given and the skills they should be taught. “What I want is to teach young people how to do basic, simple recipes like a tomato sauce, a bolognaise, a simple curry, a stir-fry – which they can use now at home and then in their later life”, said Ed Balls, the minister responsible for schools. The new lessons are due to start in September, but some school without kitchens will be given longer to adapt. There is also likely to be a shortage of teachers with the right skills, since the trend has been to teach food technology rather than practical cooking. Also the compulsory lessons for hands on cooking will only be one hour a week for one term. But the well-known cookery writer, Pru Leith, believes it will be worth it. “If we’d done this thirty years ago we might not have the crisis we have got now about obesity and lack of knowledge about food and so on. Every child should know how to cook, not just so that they’ll be healthy, but because it’s a life skill which a real pleasure”. The renewed interest in cooking is primarily a response to the level obesity in Britain which is among the highest in Europe, and according to government figures half of all Britons will be obese in 25 years if current trends are not stopped

Vocational training in the UK is intended to give people the skills and knowledge they  need to perform a particular job, and involves practical instruction as well as theory. Most vocational training takes place not in universities but in colleges of further education and in colleges specializing in art, accountancy, etc. some secondary schools now also offer an introduction to vocational training.  NVQs (National Vocational Qualifications) are qualifications that can be obtained by people already working in a particular industry. Colleges of further education run courses to provide a theoretical background. NVQs are awarded on the basis of practical work, spoken and written test, and coursework. There are five levels, from Foundation to Management. Since 1992 many students in schools and colleges have been working for GNVQs (General National Vocational Qualifications), as an alternative to GCSEs and A levels. GNVQs cover similar areas to NVQs and are intended as introductions to a particular field of work and the skills required. Students can choose from over 500 subjects. At the lowest of its three levels foundation, a GNVQ is equivalent to a GCSE and from 2002 they are being replaced by new vocational GCSEs.  In the US there are no national qualifications like NVQs, though some professional organizations decide on their own qualifications and some of these have become widely accepted. Much vocational training is done by private institutions which are sometimes called proprietary schools. Although many of these are good, in general they have a bad reputation. This is partly because there are no controls over who can operate such a school. Some proprietary schools try to get as many students as possible, including some who will probably not be able to complete their training.  Most US secondary schools programs do not provide a choice between an academic and a practical track (a program of study), but most do give students an opportunity to take some practical or vocational classes. Large school districts may have magnet schools, schools that attract students with certain interests, and some of these may have a large choice of vocational courses.

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.
9. If you have lost the thread of a story you are reading, the passage recommends ____.

Read the following passage and choose the best answer (A, B, C, D):
The town of Chichen-Itza was established during the Classic period close to two natural cavities (cenotes or chenes), which gave the town its name “At the edge of the well of the Itzaes”. The cenotes facilitated tapping the underground waters of the area. The dates for this settlement vary according to subsequent local accounts: one manuscript gives 415-35 A.D., while others mention 455 A.D. The town that grew up around the sector known as Chichen Viejo already boasted important monuments of great interest: the Nunnery, the Church, Akab Dzib, Chichan Chob, the Temple of the Panels and the Temple of the Deer. They were constructed between the 6th and the 10th centuries in the characteristic Maya style then popular both in the northern and southern areas of the Puuc hills. The second settlement of Chichen-Itza, and the most important for historians, corresponded to the migration of Toltec warriors from the Mexican plateau towards the south during the 10th century. According to the most common version, the King of Tula, Ce Acatl Topiltzin Quetzalcoatl, or Kukulkan as the Maya translated the name, reportedly took the city between 967 A.D. and 987 A.D. Following the conquest of Yucatán a new style blending the Maya and Toltec traditions developed, symbolizing the phenomenon of acculturation. Chichen-Itza is a clear illustration of this fusion. Specific examples are, in the group of buildings to the south, the Caracol, a circular stellar observatory whose spiral staircase accounts for its name, and, to the north, El Castillo. Surrounding El Castillo are terraces where the major monumental complexes were built: on the north-west are the Great Ball Court, Tzompantli or the Skull Wall, the temple known as the Jaguar Temple, and the House of Eagles; on the north-east are the Temple of the Warriors, the Group of the Thousand Columns, the Market and the Great Ball Court; on the south-west is the Tomb of the High Priest. After the 13th century no major monuments seem to have been constructed at Chichen-Itza and the city rapidly declined after around 1440 A.D. From its abandonment during the 15th century, Chichen-Itza underwent a process of gradual deterioration until the first excavations at the site began more than a century ago. Nevertheless, the excellent materials and building techniques used by the Maya in the construction of the buildings secured that the architectonic, sculptural and pictorial essence of Chichen-Itza would be conserved through the centuries

Read the following passage and choose the best answer (A, B, C, D):
Globally we use more energy than ever before, and the demand is rapidly growing. Economic expansion of emerging market economies, population growth and our increasing use of energy-consuming devices are among the most important contributing factors. About one-third of the radiation hitting Earth’s atmosphere is reflected back out into space by clouds, ice, snow, sand and other reflective surfaces. The other two-thirds is absorbed by the Earth’s surface and the atmosphere. As the land, oceans and atmosphere heat up, they re-emit energy as infrared thermal radiation, which passes through the atmosphere. Heat-trapping gases like carbon dioxide (CO2) absorb this infrared radiation and prevent it from dissipating into space, giving rise to what we know as the greenhouse effect. The accumulation of CO2 and other greenhouse gases in the atmosphere is the dominating driver of recent climate change. CO2 is estimated to be responsible for 64 % of man-made global warming. Other greenhouse gases are released in much smaller amounts but still contribute significantly to the overall warming effect, as they are much more potent heat-trapping gases than CO2. The EU is taking action on many levels. One example is on fluorinated gases that are contributing less than CO2 but still a particular point of concern in addressing climate change. They are used in several types of products, such as in refrigeration, air-conditioning and heat pump equipment. While fluorinated gases are released into the atmosphere in smaller quantities than other greenhouse gases, they are extremely potent – they produce a warming effect 23 000 times greater than CO2. For this reason the EU has decided to control their use. The EU’s regulation on fluorinated greenhouse gases aims at cutting the Union’s emissions by two-thirds compared to 2014 levels. Chemicals are not only part of the problem – they are also part of the solution. Sustainable energy sources like solar power rely on chemical innovation using, for example, nanomaterials. One of the main challenges with renewable energy is how to increase its viability with the help of energy storage solutions. For example, solar panels have the best conditions in the desert, but that is not where most people live. Windmills also produce power during the night, which is when our energy consumption is at its lowest. In other words, technologies to improve energy storage and transportation is one of the important areas of research where innovation is needed
