These following tips may help you make a good impression on your job interviewer during the interview:  

Before entering enquire by saying, "May I come in sir/madam?".

If the door was closed before you entered, make sure you shut the door behind you softly. 

Look at the interviewer and confidently say 'Good day sir/madam'.          

If the interviewer wants to shake hands, then offer a firm grip first maintaining eye contact and a smile.

Seek permission to sit down. If the interviewer is standing, wait for them to sit down first before you take your seat.

An alert interviewee would diffuse the tense situation with light-hearted humor and immediately set rapport with the interviewer.          

The interviewer normally pays more attention if you display an enthusiasm in whatever you say. This enthusiasm comes across in the energetic way you put forward your ideas.          

You should maintain a cheerful disposition throughout the interview.         

A little humor or wit thrown in the discussion occasionally enables the interviewer to look at the pleasant side of your personality.          

You must maintain eye contact with the interviewer. This shows your self-confidence and honesty. Many interviewees while answering questions, tend to look away. This conveys you are concealing your own anxiety, fear and lack of confidence. Maintaining an eye contact is a difficult process. As the circumstances in an interview are different, the value of eye contact is tremendous in making a personal impact.        

 Interviewers appreciate a natural person rather than an actor. It is best for you to talk in natural manner because then you appear genuine.

Which is not advised in a job interview?

The ocean bottom - a region nearly 2.5 times greater than the total land area of Earth - is a vast frontier that even today is largely unexplored and uncharted. Until about a century ago, the deep-ocean floor was completely inaccessible, hidden beneath waters averaging over 3,600 meters deep. Totally without light and subjected to intense pressures hundreds of times greater than at the Earth’s surface, the deep-ocean bottom is a hostile environment to humans, in some ways as forbidding and remote as the void of outer space.
Although researchers have taken samples of deep-ocean rocks and sediments for over a century, the first detailed global investigation of the ocean bottom did not actually start until 1968, with the beginning of the National Science Foundation’s Deep Sea Drilling Project (DSDP). Using techniques first developed for the offshore oil and gas industry, the DSDP’s drill ship, the Glomar Challenger, was able to maintain a steady position on the ocean’s surface and drill in very deep waters, extracting samples of sediments and rock from the ocean floor.
The Glomar Challenger completed 96 voyages in a 15-year research program that ended in November 1983. During this time, the vessel logged 600,000 kilometers and took almost 20,000 core samples of seabed sediments and rocks at 624 drilling sites around the world.. The Glomar Challenger’s core samples have allowed geologists to reconstruct what the planet looked like hundreds of millions of years ago and to calculate what it will probably look like millions of years in the future. Today, largely on the strength of evidence gathered during the Glomar Challenger’s voyages, nearly all earth scientists agree on the theories of plate tectonics and continental drift that explain many of the geological processes that shape the Earth.
The cores of sediment drilled by the Glomar Challenger have also yielded information critical to understanding the world’s past climates. Deep-ocean sediments provide a climatic record stretching back hundreds of millions of years, because they are largely isolated from the mechanical erosion and the intense chemical and biological activity that rapidly destroy much land-based evidence of past climates. This record has already provided insights into the patterns and causes of past climatic change - information that may be used to predict future climates.

The word “inaccessible” is closest in meaning to ..............

Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the questions:
The first Industrial Revolution was about harnessing steam power so that muscle could be replaced by machines. The second was driven by electricity and a cluster of  inventions from the late 19th century onwards - including the internal combustion engine, the aeroplane and moving pictures. A third revolution began in the 1960s and was based on digital technology, personal computing and the development of the internet. Industrial Revolution 4.0 will be shaped by  a  fresh wave of innovation in areas such as driverless cars, smart robotics, materials that are lighter and tougher, and a manufacturing process built around 3D printing.
There are some myths about Industrial Revolution 4.0. The first is that it won't really have as big an impact as the previous periods of change, most especially the breakthroughs associated with the second industrial revolution. In the past, it has always taken time to feel the full effects of technological change and many of today's advances are in their infancy. It is far too early to  say  that the car or air travel will prove to be less important than the sequencing of the human genome or synthetic biology. The second myth is that the process will be trouble free  provided  everything  is  left to the market. It is a fantasy to believe that the wealth created by the fourth  Industrial  Revolution will cascade down from rich to poor, and that those displaced will just walk into another job that pays just as well.
Indeed, all the evidence so far is that the benefits of the coming change will be concentrated among a relatively small elite, thus exacerbating the current trend towards greater levels of inequality. This was a point stressed by the Swiss bank UBS in a report launched in Davos. It notes that there will be a "polarisation of the labour force as low-skill jobs continue to  be automated and this trend increasingly spreads to middle class jobs,"

It is 2025. Your mobile is now much more than just a Communication device – more like a remote control for your life. You still call it a "mobile" from habit, but it is an organiser, entertainment device, payment device and security centre, all developed and manufactured by engineers.
On a typical day it will start work even before you wake. Because it knows your travel schedule it can check for problems on the roads or with the trains and adjust the time it wakes you up accordingly, giving you the best route into work. It can control your home, re-programming the central heating if you need to get up earlier and providing remote alerts if the home security system is triggered. It is your payment system - just by placing the phone near a sensor on a barrier, like the Oyster card readers in use on London transport, you can pay for tickets for journeys or buy items in shops. With its understanding of location, the mobile can also provide directions, or even alert the user to friends or family in the Vicinity.
It is your entertainment centre when away from home. As well as holding all your music files, as some phones today are able to do, it will work with your home entertainment system while you sleep to find programmes that will interest you and download them as a podcast to watch on the train or in other spare moments. It will intelligently work out what to do with incoming phone calls and messages.

Boots has reduced the price of "feminine" razors to bring them in line with men's.  The  chemist chain says it is just an isolated incident, but campaigners say it is part of a "pink tax" that discriminates against women. Who's right and what's the bigger story, ask Jessica McCallin and Claire Bates. Campaigners against what's been dubbed the "pink tax" - where retailers charge women more than men for similar products - are celebrating after Boots said it would change the price of some of     its goods.
Stevie Wise, who launched the petition, was driven by a Times investigation which claimed that women and girls are charged, on average, 37% more for clothes, beauty products and toys. The New  York Department of Consumer Affairs had compared the prices of 800 products with male and female versions and concluded that, after controlling for quality, women's versions were, on average, 7% more expensive than men's.
“This is a very exciting response,” says Wise. We are delighted with Boots' decision, but we now need to get them to look at all of their products, not just the ones highlighted in the petition. We  hope this decision is just the first of many and we may broaden our campaign to focus on other retailers  as well." Wise says that women have been getting in touch with examples of other price discrepancies from lots of companies and says there seems to be a particular problem with toys and clothes. Argos has been criticized for identical scooters that cost £5 more if they were pink rather than blue. Argos said it was an error that had already been rectified and that it would never indulge in differential pricing.
Among the examples sent to Wise was Boots selling identical child car seats that cost more in pink. Another retailer was selling children's balance bikes which cost more for a flowery print aimed at girls than a pirate print aimed at boys. But the latter example already appears to have been tweaked on the retailer's website, albeit by applying a £10 discount to the flowery version.
When challenged over sexist pricing, both Levi's and Tesco argued that different versions of things could have different production costs even if appearing fairly similar. Prof Nancy Puccinelli says her research suggests that women are much more careful shoppers than men, better able to scrutinise adverts and pricing gimmicks. She wonders if women are perceiving more value in the more expensive products. “If products are separated into male and female sections far away from each other it's harder to scrutinise prices.” Such a situation could either be deliberate or accidental but the campaigners are not convinced.
There is an opportunity for some companies, argues Olchawski. “The finding shows the power of marketing in our lives, how it shapes our perception of what it means to be a man or a woman. Some companies could choose not to play into this, not to play into the stereotypes and rip women off,  but  launch products more in tune with moves toward gender equality.”

Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the questions:
Nature has always provided a stimulus for inventive minds. Early flying machines clearly were an attempt to emulate the freedom of birds. Architects and engineers have often consciously modeled buildings on forms found in nature. A more recent example of the inspiration given by nature is the invention of Velcro®. The inventor of this now common fastening device noticed that small burrs attached to his dog's coat grasped the hairs by means of tiny hooks. This led him to invent a synthetic fabric whose surfaces mimic the clasping properties of this natural seedpod.
Animals and plants have evolved solutions to the kinds of problems that often interest engineers  and designers. Much current research in material science is concerned with actively examining the natural world, especially at the molecular level, for inspiration to develop materials with novel properties. This relatively new field of study is sometimes known as biomimetics, since it consciously attempts to mimic nature.
Researchers have investigated several interesting areas. For example, they have studied how the molecular structure of antler bone contributes to its amazing toughness, how the skin structure of a worm contributes to its ability to crawl, how the sea cucumber softens its skeleton and changes shape so that it can squeeze through tiny gaps in rocks, or what gives wood its high resistance to impact. These investigations have led to several breakthroughs in the development of composite materials with remarkable properties.
Predictions for future inventions that may be developed from these lines of research include so- called smart structures that design and repair themselves in a similar way to a variety of processes in the natural world. For example, engineers have envisaged bridges that would detect areas heavily stressed by vehicle movement or wind. The bridge structure would then automatically add or move material to the weak areas until the stress is reduced. The same principle might be used to repair damaged buildings. Other new materials that have been imagined are substances that would copy photosynthesis in green plants in order to create new energy sources. The potential impact of biomimetic research is so great that the twenty-first century may come to be known as the "Age of Materials."

Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the questions:
When people hear the word “city”, they usually imagine concrete, neon signs, and lots of air pollution. Thanks to some clever and concerned architects, this image is starting to change. The concept of green cities aims to bring some beauty from rural environments into urban areas. It is not only about looking better though. Green cities are also trying to improve the efficiency of cities and raise the standard of living for people who stay in them.
The term “green cities” refers to cities where builders take into account several environmental factors before that city is constructed or redesigned. For starters, green cities are designed to be more physically appealing than traditional cities from the past. In addition, the mobility of citizens should be considered, so public transportation can be more convenient and travel time to work can be reduced. Energy sources should also be evaluated with the goal of minimizing air pollution.
When it comes to going green, the city of Barcelona is far ahead of its time. Since 1859, its designers have consciously tried to create sustainable urban designs. Then in 1992, the city received a well-deserved makeover before hosting the Olympic Games. In recent years, Barcelona has upgraded its transportation system. This has reduced air pollution as more and more workers are using public transportation instead of their own vehicles. Barcelona also boasts one of the best recycling programmes in the world. Visitors will find clear, colour-coded trash bins throughout the city where they can put all of their materials.
It is no secret in Portland, Oregon is one of the greenest cities in the US. Since 1903, it has been an example of what American cities can accomplish with careful planning. Instead of filling its area with office buildings, Portland has plenty of green space for activities. There are 119 kilometres of running, hiking, and bike trails that allow citizens to experience the great outdoors. The city also offers residents creative energy plans that give them the opportunity to pay a bit extra for clean energy sources. For about
$3 to $9 extra each month, homeowners can choose solar or wind power and help the environment.
These are only a small sampling of the green cities around .the world. As more people experience the pleasure of visiting green cities, it seems certain that the trend of urban areas going green will continue far into the future.

How does the author seem to feel about the future of green cities?

      Anthropogenic global warming is a theory explaining today's long-term increase in the average temperature of Earth's atmosphere as an effect of human industry and agriculture.
      Since the latter half of the 20th century, growing banks of data and improved climate models have convinced most climate scientists that rising trends in greenhouse gas emissions are directly responsible for a rising trend in atmospheric temperature. The source of these emissions vary, consisting of a mix of gases that include methane and carbon dioxide. While some sources - such as volcanoes - are natural, their overall emissions compared with those produced by human industries, transport, and livestock have been regarded as insignificant over recent centuries.
       Greenhouse gases are made of molecules that absorb electromagnetic radiation, such as  the light reflecting from the planet's surface, and re-emit it as heat. These gases include methane, carbon dioxide, water, and nitrous oxide. Despite making up only a small percentage of the atmosphere's mix of gases they are very important. If we had no naturally occurring greenhouse gases in the atmosphere at all, the average global temperature on Earth would be a much lower -18 degrees instead of the roughly 15 degrees Celsius we have enjoyed most of human history.
        Carbon dioxide levels have steadily risen over the past two centuries, thanks largely to the burning of fossil fuels for electricity general, transportation, and smelting. Current levels are approximately 415 parts per million (ppm), up from pre-industrial levels of around 280 ppm. Models vary in their predictions of further temperature increases, and depend heavily on future trends in greenhouse gas emissions. Conservative estimates by the Intergovernmental Panel on Climate Change predict an even chance of 4 degrees Celsius rise by the end of the century if current emissions trends continue.

Since the world became industrialized, the number of animal species that have either become extinct or near extinction has increased. Bengal tigers, for instance, which once roamed the jungles in vast numbers, now number only about 2,300. By the year 2025, it is estimated that they will become extinct.
What is alarming about the case of the Bengal tiger is that this extinction will have been caused almost entirely by poachers who, according to some sources, are not always interested in material gain but in personal gratification. This is an example of the callousness that is contributing to the problem of extinction. Animals such as the Bengal tiger, as well as other endangered species, are valuable parts of the world/s ecosystem. International laws protecting animals must be enacted to ensure their survival-and the survival of our planet.
Countries around the world have begun to deal with the problem in various ways. Some countries, in an effort to circumvent the problem, have allocated large amounts of land to animal reserves. They then charge admission prices to help defray the costs of maintaining the parks, and they often must also depend on world organizations for support. This money enables them to invest in equipment and patrols o protect the animals. Another response to the increase in animal extinction is an international boycott of products made from endangered species. This has had some effect, but by itself will not prevent animals from being hunted and killed.

People in the UK enjoy fewer years of good health before they die than the citizens of most comparable European countries as well as Australia and Canada, a major report shows. While life expectancy has improved by 4.2 years in the UK over the two decades, other countries have improved faster. In 2010, Spain topped the league. Its people could expect 70.9 years of healthy life - before disease and disability began to take a toll. Second came Italy, with 70.2 years and third was Australia, on 70.1 years. In the UK, we can expect 68.6 healthy years of life.
Hunt said the UK was a long way behind its global counterparts and called for action by local health commissioners to tackle the five big killers - cancer, heart disease, stroke, respiratory and liver diseases. Drinking and drug use have been the main issues behind the worsening of the UK's ranking in early deaths among adults aged 20-54. In 2010, drugs were the sixth leading cause of death in this age group and alcohol was 18th - up from 32nd and 43rd place respectively 20 years earlier.
Hunt will on Tuesday announce a strategy to tackle cardiovascular disease, which he says could save 30,000 lives a year. "Despite real progress in cutting deaths, we remain a poor relative to our global cousins on many measures of health, something I want to change," he said. "For too long we have been lagging behind and I want the reformed health system to take up this challenge and turn this shocking underperformance around.” However, the problem is only in part to do with hospital care - much of it is about the way we live. Our diet, our drinking and continuing smoking habits all play a part, which assumes its responsibilities on 1 April.

Carnegie Hall, the famous concert hall in New York City, has again undergone a restoration. While this is not the first, it is certainly the most extensive in the building’s history. As a result of this new restoration, Carnegie Hall once again has the quality of sound that it had when it was first built.
Carnegie Hall owes its existence to Andrew Carnegie, the wealthy owner of a steel company in the late 1800s. The hall was finished in 1891 and quickly gained a reputation as an excellent performing arts hall where accomplished musicians gained fame. Despite its reputation, however, the concert hall suffered from several detrimental renovations over the years. During the Great Depression, when fewer people could afford to attend performances, the directors sold part of the building to commercial businesses. As a result, a coffee shop was opened in one corner of the building, for which the builders replaced the brick and terra cotta walls with windowpanes. A renovation in 1946 seriously damaged the acoustical quality of the hall when the makers of the film Carnegie Hall cut a gaping hole in the dome of the ceiling to allow for lights and air vents. The hole was later covered with short curtains and a fake ceiling, but the hall never sounded the same afterwards.
In 1960, the violinist Isaac Stern became involved in restoring the hall after a group of real estate developers unveiled plans to demolish Carnegie Hall and build a high-rise office building on the site. This threat spurred Stern to rally public support for Carnegie Hall and encourage the City of New York to buy the property. The movement was successful, and the concert hall is now owned by the city. In the current restoration, builders tested each new material for its sound qualities, and they replaced the hole in the ceiling with a dome. The builders also restored the outer walls to their original appearance and closed the coffee shop. Carnegie has never sounded better, and its prospects for the future have never looked more promising.

What was probably the most important aspect of the recent renovation?

Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the questions:
Telecommuting-substituting the computer for the trip to the job-has been hailed as a solution to all kinds of problems related to office work. For workers, it promises freedom from the office, less time wasted in traffic, and help with child-care conflicts. For management, telecommuting helps keep high performers on board, minimizes tardiness and absenteeism by eliminating commutes, allows periods of solitude for high-concentration tasks, and provides scheduling flexibility. In some areas, such as Southern California and Seattle, Washington, local governments are encouraging companies to start telecommuting programs in order to reduce rush-hour congestion and improve air quality, but these benefits do not come easily. Making a telecommuting program work requires careful planning and an understanding of the differences between telecommuting realities and popular images.
Many workers are seduced by rosy illusions of life as a telecommuter. A computer programmer from New York City moves to the tranquil Adirondack Mountains and stays in contact with her office via computer. A manager comes into his Office three days a week and works at home the other two. An accountant stays home to care for child; she hooks up her telephone modem connections and does office work between calls to the doctor.
These are powerful images, but they are a limited reflection of reality. Telecommuting workers soon learn that it is almost impossible to concentrate on work and care for a young child at the same time. Before a certain age, young children cannot recognize, much less respect, the necessary boundaries between work and family. Additional child support is necessary if the parent is to get any work done.
Management, too, must separate the myth from the reality. Although the media has paid a great deal of attention to telecommuting, in most cases it is the employee’s situation, not the availability of technology, that precipitates a telecommuting arrangement.
That is partly why, despite the widespread press coverage, the number of companies with work-at-home programs or policy guidelines remains small.

Which of the following does the author mention as a possible disadvantage of telecommuting?

Millions of people are using cell phones today. In many places, it is actually considered unusual not to use one. In many countries, cell phones are very popular with young people. They find that the phones are more than a means of communication - having a mobile phone shows that they are cool and connected.

The explosion in mobile phone use around the world has made some health professionals worried. Some doctors are concerned that in the future many people may suffer health problems from the use of mobile phones. In England, there has been a serious debate about this issue. Mobile phone companies are worried about the negative publicity of such ideas. They say that there is no proof that mobile phones are bad for your health.

On the other hand, medical studies have shown changes in the brain cells of some people who use mobile phones. Signs of change in the tissues of the brain and head can be detected with modern scanning equipment. In one case, a traveling salesman had to retire at young age because of serious memory loss. He couldn't remember even simple tasks. He would often forget the name of his own son. This man used to talk on his mobile phone for about six hours a day, every day of his working week, for a couple of years. His family doctor blamed his mobile phone use, but his employer's doctor didn't agree.

What is it that makes mobile phones potentially harmful? The answer is radiation. High-tech machines can detect very small amounts of radiation from mobile phones. Mobile phone companies agree that there is some radiation, but they say the amount is too small to worry about.

As the discussion about their safety continues, it appears that it's best to use mobile phones less often. Use your regular phone if you want to talk for a long time. Use your mobile phone only when you really need it. Mobile phones can be very useful and convenient, especially in emergencies. In the future, mobile phones may have a warning label that says they are bad for your health. So for now, it's wise not to use your mobile phone too often

It weighed about 10,000 tons, entered the atmosphere at a speed of 64,000 km/h and exploded over a city with a blast of 500 kilotons. But on 15 February 2013, we were lucky. The meteorite that showered pieces of rock over Chelyabinsk, Russia, was relatively small, at only about 17 metres wide. Although many people were injured by falling glass, the damage was nothing compared to what had happened in Siberia nearly one hundred years ago. Another relatively small object (approximately 50 metres in diameter) exploded in mid–air over a forest region, flattening about 80 million trees. If it had exploded over a city such as Moscow or London, millions of people would have been killed.
By a strange coincidence, the same day that the meteorite terrified the people of Chelyabinsk, another 50m–wide asteroid passed relatively close to Earth. Scientists were expecting that visit and know that the asteroid will return to fly close by us in 2046, but the Russian meteorite earlier in the day had been too small for anyone to spot.
Most scientists agree that comets and asteroids pose the biggest natural threat to human existence. It was probably a large asteroid or comet colliding with Earth which wiped out the dinosaurs about 65 million years ago. An enormous object, 10 to 16 km in diameter, struck the Yucatan region of Mexico with the force of 100 megatons. That is the equivalent of one Hiroshima bomb for every person alive on Earth today.
Many scientists, including the late Stephen Hawking, say that any comet or asteroid greater than 20 km in diameter that hits Earth will result in the complete destruction of complex life, including all animals and most plants. As we have seen, even a much smaller asteroid can cause great damage.
The Earth has been kept fairly safe for the last 65 million years by good fortune and the massive gravitational field of the planet Jupiter. Our cosmic guardian, with its stable circular orbit far from the sun, sweeps up and scatters away most of the dangerous comets and asteroids which might cross Earth’s orbit. After the Chelyabinsk meteorite, scientists are now monitoring potential hazards even more carefully but, as far as they know, there is no danger in the foreseeable future.

All of the following statements are true EXCEPT    .

You have learned about dinosaurs in school. Maybe you have seen them in museums. But how much do you really know about these animals? Not all dinosaurs were just big reptiles. For years, scientists thought dinosaurs were big, dumb, and cold blooded - in other words, just giant reptiles. Some dinosaurs were huge. But many were about the size of modern-day birds or dogs. Were dinosaurs warm- or cold blooded? Paleontologists- are not sure. But they believe some were intelligent. Of course, no dinosaur was as smart as a human or even a monkey. However, some smaller dinosaurs - like the two- meter (six-foot) Troodon — had fairly large brains.
Was Tyrannosaurus rex a powerful predator? Some scientists think the opposite is true. In the movies, T.rex is often a speedy giant, but in fact, this dinosaur could not run very fast. Physically, it was too large. In reality, T.rex probably moved as fast as an elephant. Also, T. rex had very small arms. Without strong legs or arms, this dinosaur probably wasn’t a powerful hunter. It may have been a scavenger instead, only eating animals that were already dead.
Did an asteroid kill the dinosaurs? An asteroid hit Mexico’s Yucantan Peninsula about 65 million years ago. It created a 180-kilometer (HO-mile) wide crater called Chicxulub. Many believe this asteroid caused the extinction of the dinosaurs. But even before this, dinosaurs were already dying out around the world, for many reasons. At the end of the Cretaceous period, for example, the global climate was changing and Earth's temperature was getting colder.Dinosaurs completely disappeared about 65 million years ago. However, scientists believe modern-day birds are descendants of certain dinosaurs. If this  true, then dinosaurs' relatives are still walking - and flying - among us!

The word "descendants" in paragraph 4 means     .

In the United States in the early 1800's, individual state governments had more effect on the economy than did the federal government. States chartered manufacturing, banking, mining, and transportation firms and participated in the construction of various internal improvements such as canals, turnpikes, and railroads. The states encouraged internal improvements in two distinct ways; first, by actually establishing state companies to build such improvement; second, by providing part of the capital for mixed public-private companies setting out to make a profit.
In the early nineteenth century, state governments also engaged in a surprisingly large amount of direct regulatory activity, including extensive licensing and inspection programs. Licensing targets reflected both similarities in and differences between the economy of the nineteenth century and that of today: in the nineteenth century, state regulation through licensing fell especially on peddlers, innkeepers, and retail merchants of various kinds. The perishable commodities of trade generally came under state inspection, and such important frontier staples as lumber and gunpowder were also subject to state control. Finally, state governments experimented with direct labor and business regulation designed to help the individual laborer or consumer, including setting maximum limits on hours of work and restrictions on price-fixing by businesses.
Although the states dominated economic activity during this period, the federal government was not inactive. Its goals were the facilitation of western settlement and the development of native industries. Toward these ends the federal government pursued several courses of action. It established a national bank to stabilize banking activities in the country and, in part, to provide a supply of relatively easy money to the frontier, where it was greatly needed for settlement. It permitted access to public western lands on increasingly easy terms, culminating in the Homestead Act of 1862, by which title to land could be claimed on the basis of residence alone. Finally, it set up a system of tariffs that was basically protectionist in effect, although maneuvering for position by various regional interests produced frequent changes in tariff rates throughout the nineteenth century.

All of the following are mentioned in the passage as areas that involved state governments in the nineteenth century EXCEPT
