The word robot first appeared in a 1921 stage play by Czech writer Karel Capek. In the play, a man makes a machine that can think, which he calls a robot and which ends up killing its owner. In the 1940s, the American science fiction writer Isaac Asimov wrote a series of stories about robots and invented the term robotics, the science of robots. Meanwhile, in the real world, the first robots were developed by an engineer, Joseph F. Engelberger, and an inventor, George C. Devol. Together they started Unimation, a manufacturing company that produces the first real robot in 1961, called the Unimate. Robots of this type were installed at a General Motors automobile plant and proved to be a success. They worked reliably and saved money for General Motors, so other companies were soon acquiring robots as well.
These industrial robots were nothing like the terrifying creatures that can often be seen in science fiction films. In fact, these robots looked and behaved nothing like humans. They were simply pieces of computer-controlled machinery, with metal “arms” or “hands”. Since they were made of metal, they could perform certain jobs that were difficult or dangerous for humans, particularly jobs that involve high heat. And since robots were tireless and never got hungry, sleepy, or distracted, they were useful for tasks that would be tiring or boring for humans. Industrial robots have been improved over the years, and today they are used in many factories around the world. Though the use of robots has meant the loss of some jobs, at the same time other jobs have been created in the design, development, and production of the robots.

What can be said about Karel Capek?

The legal limit for driving after drinking alcohol is 80 milligrams of alcohol in 100 milliliters of blood, when tested. But there is no sure way of telling how much you can drink before you reach this limit. It varies with each person depending on your weight, your sex, if you’ve just eaten and what sort of drinks you’ve had. Some people might reach their limit after only about three standard drinks.
In fact, your driving ability can be affected by just one or two drinks. Even if you’re below the legal limit, you could still be taken to court if a police officer thinks your driving has been affected by alcohol.
It takes about an hour for the body to get rid of the alcohol in one standard drink. So, if you have a heavy drinking session in the evening you might find that your driving ability is still affected the next morning, or you could even find that you’re still over the legal limit. In addition, if you’ve had a few drinks at lunchtime, another one or two drinks in the early evening may well put you over the legal limit.
In a test with professional drivers, the more alcoholic drinks they had had the more certain they were that they could drive a test course through a set of moveable posts … and the less able they were to do it!
So the only way to be sure you’re safe is not to drink at all.
Alcohol is a major cause of road traffic accidents. One in three of the drivers killed in road accidents have levels of alcohol which are over the legal limit, and road accidents after drinking are the biggest cause of death among young men. More half of the people stopped by the police to take a breathalyzer test have a blood alcohol concentrate of more than twice the legal limit.
It is important to remember that driving after you’ve been drinking doesn’t just affect you. If you’re involved in an accident it affects a lot of other people as well, not least the person you might kill or injure. 

When might you be taken to court by the police for drinking and driving?

   Different cultures follow their own special customs when a child's baby teeth fall out. In Korea, for example, they have the custom of throwing lost teeth up on the roof of a house. According to tradition, a magpie will come and take the tooth. Later, the magpie will return with a new tooth for the child. In other Asian countries, such as Japan and Vietnam, children follow a similar tradition of throwing their lost teeth onto the roofs of houses.

   Birds aren't the only animals thought to take lost teeth. In Mexico and Spain, tradition says a mouse takes a lost tooth and leaves some money. However, in Mongolia, dogs are responsible for taking teeth away. Dogs are highly respected in Mongolian culture and are considered guardian angels of the people. Tradition says that the new tooth will grow good and strong if the baby tooth is fed to a guardian angel. Accordingly, parents in Mongolia will put their child's lost tooth in a piece of meat and feed it to a dog.

   The idea of giving lost teeth to an angel or fairy is also a tradition in the West. Many children in Western countries count on the Tooth Fairy to leave money or presents in exchange for a tooth. The exact origins of the Tooth Fairy are a mystery, although the story probably began in England or Ireland centuries ago. According to tradition, a child puts a lost tooth under his or her pillow before going to bed. In the wee hours, while the child is sleeping, the Tooth Fairy takes the tooth and leaves something else under the pillow. In France, the Tooth Fairy leaves a small gift. In the United States, however, the Tooth Fairy usually leaves money. These days, the rate is $1 to $5 per tooth, adding up to a lot of money from the Tooth Fairy!

According to the passage, where is a child's lost tooth thought to be taken away by a mouse?

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 concept of being environmentally conscious, or “green”, has become more prevalent in twenty first-century U.S culture. It has begun to affect the manufacturing of everything from non-toxic household cleaning products to motor vehicles powered by alternative sources of energy. However, one way of being “green” that is perhaps not as apparent to the viewer but of equal importance in being environmentally conscious, is the construction of buildings that are considered “sustainable”. Sustainable buildings are those that do not impose on the environment or rely on the over-utilization of energy or natural resources. There are four main principles of sustainability, which includes consideration of the health and stability of all living things and their environmental diversity, as well as the economic opportunities of humanity.
Sustainable architecture consists of environmentally conscious design techniques. In the past, the demolition of an old building meant that all or most of the debris of the building would end up in a landfill or a waste disposal site. Today, architects can plan and design a building that uses recycled materials, such as wood, concrete, stone, or metal. These materials are salvaged from the demolition of an older building and can be appropriately incorporated into a new construction. Architects and construction supervisors may also choose to recycle more organic parts of demolished buildings, such as wooden doors, windows and other glass, ceramics, paper, and textiles.
A problem that has often arisen has been with how a site crew-whether it is demolition or construction crew determines and sorts what is “waste” and what is recyclable. Architects and environmental scientists have to decide whether or not a material is appropriate for use in new construction and how it will impact the environment. They must evaluate the materials from the demolition and determine what those materials contain, and if they meet the standards set by the U.S, government’s Environmental Protection Agency (the EPA). If the debris from the demolition contains hazardous materials that are harmful to the environment or to the consumer, such as asbestos, then the material is not salvageable. Use of the asbestos for insulation and as a form of fire retardation in buildings and fabrics was common in the nineteenth century. Asbestos was once used in shingles on the sides of buildings, as well as in the insulation in the interior walls of homes or other construction. In new “green” construction, insulation that once asbestos- based can be replaced with recycled denim or constructed with cellulose-a fibrous material found in paper products. The same-assessment applies to wood or wallboard painted with toxic lead-based paints. In addition, gas-flow regulators and meters on both water and gas heating systems constructed prior to 1961 must be carefully evaluated to determine that they do not contain dangerous substances such as mercury. Mercury can be harmful to humans and the environment if it is spilled during the removal of these devices.

In paragraph 3, the author mention both demolition and construction crews in order to

Since the first Paralympic Games in Rome in 1960, swimming has been one of its main sports.
The thrill of competition aside, swimming offers many benefits including strengthening the cardiovascular systems and the major muscle groups of both the upper and lower body. It also develops flexibility in the muscles and joints as the swimmer performs a wide range of motion against the water's resistance. It is an activity that keeps your heart rate up but takes some of the stress that is common in impact sports off the body; injuries don't occur as easily. The water's buoyancy evenly distributes and supports the weight of the body; there is no danger of falling, and there are no impact forces on the residual limb. Swimmers who have disabilities endorse the sport because it gives them a sense of freedom. They don't have to rely on any supportive device, such as a wheelchair, to assist them. They are independent. They are only judged on their times and whether those times are dropping. “Water is one of the big equalizers,” said Queenie Nichols, long-time Paralympic swim coach. "One of the phrases I heard since I got involved in this is that we are all equal in the water and that is really true. Athletes with disabilities, from below-knee amputations to severe quads, can compete and compete successfully.”
While it is not essential to begin swimming at an early age to become an elite athlete, Nichols believes that the sooner an individual becomes comfortable in the water, the better. "I think starting at about 5 years old is a good age to get children involved, in the pool at least once a week. Keep it fun for them until they show an interest in growing with a Club," she said.
“Most clubs that belong to USA Swimming or YMCAs offer coaching and training at the appropriate level for age and experience,” Nichols said. "We suggest aspiring athletes participate with an able-bodied club at first because of the greater number of individuals they will compete with."
Typically, swimmers in this introductory/ foundation phase, usually aged 5 to 8 or 9, remain there for about 5 years before transitioning to the next level, which includes more advanced drills and stroke efficiency. Athletes with disabilities who join swimming clubs benefit from better sport-specific coaching, more rigorous training, more competition in practice, and higher expectations than they are likely to receive in other settings. Other benefits include socialization opportunities, greater independence in activities of daily living, and improved ability to cope with limitations imposed by disabilities.

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. 
     As customers choose brands based on how they make them feel, rather than their actual products or services, there is an intrinsic advantage to those organizations who use designed experiences as a weapon to cut through the most competitive of markets. Those that don’t, operate in what we call the “experience gap”, the space between them and their customer’s expectation of them. Make no mistake, in our high paced and digitally connected economies, the experience gap is driving markets, fast.
     For example, take Instagram and Twitter. These brands filled the demand for a whole new human experience that did not exist before the evolution of digital technologies enabled that. They were pioneers, and there were no established players to unseat. But we are also seeing a similar dynamic in existing industries. New entrants are coming in and taking the space, also using whole new experiences, purely because the incumbents left the door open.
    Closer to home, this can be seen with Australian neobanks who are giving customers a better experience than the incumbents. Robert Bell is the CEO at neobank 86400. He says banking has already become quite complicated and he wanted to make a change. His neobank is working to solve customers problems more holistically. Bell said, “It’s significantly harder work and takes more time to become a bank, but having done that we can have a much better relationship with our customers and we can offer them a lot more products and services.”
      Think about that for a moment. Do you notice how better experiences, leads to better relationships, which is then the stepping stone for more offerings? Many brands still jump straight to modified offerings, without gaining that customer connection and the necessary foundation of trust first.

What does the phrase “stepping stone” in paragraph 4 mean?

There are a number of natural disasters that can strike across the globe. Two that are frequently linked to one another are earthquakes and tsunamis. Both of them can cause a great amount of devastation when they hit. However, tsunamis are the direct result of earthquakes and cannot happen without them.
The Earth has three main parts. They are the crust, the mantle, and the core. The crust is the outer layer of the Earth. It is not a single piece of land. Instead, it is comprised of a number of plates.
There are a few enormous plates and many smaller ones. These plates essentially rest upon the mantle, which is fluid. As a result, the plates are in constant – yet slow – motion. The plates may move away from or toward other plates. In some cases, they collide violently with the plates adjoining them. The movement of the plates causes tension in the rock. Over a long time, this tension may build up. When it is released, an earthquake happens.Tens of thousands of earthquakes happen every year. The vast majority are so small that only scientific instruments can perceive them. Others are powerful enough that people can feel them, yet they cause little harm or damage. More powerful earthquakes, however, can cause buildings, bridges, and other structures to collapse. They may additionally injure and skill thousands of people and might even cause the land to change it appearance.
Since most of the Earth’s surface is water, numerous earthquakes happen beneath the planet’s oceans. Underwater earthquakes cause the seafloor to move. This results in the displacement of water in the ocean. When this occurs, a tsunami may form. This is a wave that forms on the surface and moves in all directions from the place where the earthquake happened. A tsunami moves extremely quickly and can travel thousnads of kilometres. As it approaches land, the water near the coast gets sucked out to sea. This causes the tsunamis to increase in height.
Minutes later, the tsunami arrives. A large tsunami – one more than ten meters in height – can travel far inland. As it does that, it can flood the land, destroy human settlements, and kill large numbers of people

More often than not, you can't just "order up a job" by responding to an online posting and have it delivered in one or two days as if you were buying whatever your heart desires on Amazon.  Even as employers are hiring at a higher rate than they have in the last several years, it can often take months to work your way through the job search process. If you are a new graduate yet to receive a job offer, if you recently moved to a new locale with your spouse or partner or if you   are unemployed for any other reason, you may find success in your job search by spending time volunteering at a nonprofit organization.
Both the nonprofit and for-profit worlds need people with many of the same talents. The best volunteer jobs for you to consider are ones where the experience you acquire will be applicable in the "for-pay" position you want to attain. It's often the case that once you display your passion for the organization and its mission, and have demonstrated your abilities, you'll earn strong consideration when a paying position opens up that can benefit from your talents. Even if you don't have a path to employment at the place you volunteer, by highlighting your volunteer experience on your resume,  you can demonstrate that you haven't been wasting your time away staying at home watching the grass grow.
There are a few strategies you might adopt when considering at  which organization you'll  want to volunteer. You' ll probably want to make a priority of volunteering to do what you've already done, or want to do, in the for-profit sector. Alternatively, however, it might make sense to volunteer to do something where you can turn an area of professional weakness into a new strength. Remember, as well, that nonprofit organizations maintain strong relationships with their corporate sponsors, and you might look for a volunteer position that would enable you to be that nexus point between the two. And, especially if you are recently out of school, you should look for positions  that let you learn about an occupation, a field of interest or an industry.
As you try to determine what you want to volunteer to do, and where you want to do it, make three lists: your marketable skills, the roles you seek and the kinds of charitable organizations you would want to support. For example, perhaps your skills cluster around accounting, marketing or event planning. Think about how these might come in handy for organizations that need financial help figuring out how to brand the organization to attract other volunteers or donors or run anything from charitable golf tournaments to gala dinners.

Which of the  following could best describe the  author's attitude about volunteering when being unemployed?

The first thing to do when you have a trip abroad is to check that your passport is valid. Holders of out–of–date passports are not allowed to travel overseas. Then you can prepare for your trip. If you don't know the language, you can have all kinds of problems communicating with local people. Buying a pocket dictionary can make a difference. You'll be able to order food, buy things in shops and ask for directions. It's worth getting one. Also there's nothing worse than arriving at your destination to find there are no hotels available. The obvious way to avoid this is to book in advance. This can save you money too. Another frustrating thing that can happen is to go somewhere and not know about important sightseeing places. Get a guide book before you leave and make the most of your trip. It's a must.
Then, when you are ready to pack your clothes, make sure they are the right kind. It's no good packing sweaters and coats for a hot country or T–shirts and shorts for a cold one. Check the local climate before you leave.
Also, be careful how much you pack in your bags. It's easy to take too many clothes and then not have enough space for souvenirs. But make sure you pack essentials. What about money? Well, it's a good idea to take some local currency with you but not too much. There are conveniently located cash machines (ATMs) in most big cities, and it's usually cheaper to use them than change your cash in banks. Then you'll have more money to spend. When you are at your destination, other travellers often have great information they are happy to share. Find out what they have to say. It could enhance your travelling experience.

According to the passage, you should do all of the following before leaving EXCEPT

In the American colonies there was little money. England did not supply the colonies with coins and did not allow the colonies to make their own coins, except for the Massachusetts Bay Colony, which received permission for a short period in 1652 to make several kinds of silver coins. England wanted to keep money out of America as a means of controlling trade: America was forced to trade only with England if it did not have the money to buy products from other countries. The result during this pre-revolutionary period was that the colonists used various goods in place of money: beaver pelts, Indian wampum, and tobacco leaves were all commonly used substitutes for money. The colonists also made use of any foreign coins they could obtain. Dutch, Spanish, French, and English coins were all in use in the American colonies.
During the Revolutionary War, funds were needed to finance the world, so each of the individual states and the Continental Congress issued paper money. So much of this paper money was printed that by the end of the war, almost no one would accept it. As a result, trade in goods and the use of foreign coins still flourished during this period.
By the time the Revolutionary War had been won by the American colonists, the monetary system was in a state of total disarray. To remedy this situation, the new Constitution of the United States, approved in 1789, allowed Congress to issue money. The individual states could no longer have their own money supply. A few years later, the Coinage Act of 1792 made the dollar the official currency of the United States and put the country on a bimetallic standard. In this bimetallic system, both gold and silver were legal money, and the rate of exchange of silver to gold was fixed by the government at sixteen to one.

According to the passage, which of the following is NOT true about the bimetallic monetary system?

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:
If "suburb" means an urban margin that grows more rapidly than its already developed interior,  the process of suburbanization began during the emergence of the industrial city in the second quarter of the nineteenth century. Before that period the city was a small highly compact cluster in which people moved about on foot and goods were conveyed by horse and cart. But the early factories built in the 1830's and 1840's were located along waterways and near railheads at the edges of cities, and housing was needed for the thousands of people drawn by the prospect of employment. In time, the factories were surrounded by proliferating mill towns of apartments and row houses that abutted the older, main cities.
As a defense against this encroachment and to enlarge their tax bases, the cities appropriated their industrial neighbors. In 1854, for example, the city of Philadelphia annexed most of Philadelphia County. Similar municipal maneuvers took place in Chicago and in New York. Indeed, most great cities of the United States achieved such status only by incorporating the communities along their borders.
With the acceleration of industrial growth came acute urban crowding and accompanying social stress conditions that began to approach disastrous proportions when, in 1888, the first commercially successful electric traction line was developed. Within a few years the horse-drawn trolleys were retired and electric streetcar networks crisscrossed and connected every major urban area, fostering a wave of suburbanization that transformed the compact industrial city into a dispersed metropolis. This first phase of mass-scale suburbanization was reinforced by the simultaneous emergence of the urban Middle class 64whose desires for homeownership in neighborhoods far from the aging inner city were satisfied by the developers of single-family housing tracts.

Continents and ocean basins represent the largest identifiable bodies on Earth. On the solid portions of the planet, the second most prominent features are flat plains, elevated plateaus, and large mountain ranges. In geography, the term "continent" refers to the surface of continuous landmasses that together comprise about 29.2% of the planet's surface. On the other hand, another definition is prevalent in the general use of the term that deals with  extensive main lands, such as Europe or Asia, that actually represent one   very large landmass. Although all continents are bounded by the water bodies or high mountain ranges, isolated main lands, such as Greenland and India-Pakistan areas are called subcontinents. In some circles, the distinction between continents and large islands lies almost exclusively in the size of a particular landmass.
The analysis of compression and tension in the earth's crust has determined that continental structures are composed of layers that underlie continental shelves. A great deal of disagreement among geologists surrounds the issue of exactly how many layers underlie each landmass because of their distinctive mineral and chemical composition. It's also quite possible that the ocean floor rests on top of unknown continents that have not yet been explored. The continental crust is believed to have been formed by means of a chemical reaction when lighter materials separated from heavier ones, thus settling at various levels within the crust. Assisted by the measurements of the specifics within crust formations by means of monitoring earthquakes, geologists can speculate that a chemical split occurred to form the atmosphere, sea water and the crust before it solidified many centuries ago.
Although each continent has its special features, all consist of various combinations of components that include shields, mountain belts, intra - cratonic basins, margins, volcanic plateaus, and block-vaulted belts. The basic differences among continents lie in the proportion and the composition of these features relative to the continent size. Climatic zones have a crucial effect on the weathering and formation of the surface features, soil erosion, soil deposition, land formation, vegetation, and human activities.
Mountain belts are elongated narrow zones that have a characteristic folded sedimentary organization of layers. They are typically produced during substantial crustal movements, which generate faulting and mountain building. When continental margins collide, the rise of a marginal edge leads to the formation of large mountain ranges, as explained by the plate tectonic theory. This process also accounts for the occurrence of mountain belts in ocean basins and produces evidence for the ongoing continental plate evolution.

The word "bounded" is closest in meaning to .

A few years later, the Coinage Act of 1792 made the dollar the official currency of the United States and put the country on a bimetallic standard. In this bimetallic system, both gold and silver were legal money, and the rate of exchange of silver to gold was fixed by the government at sixteen to one.

The passage indicates that during the colonial period, money was

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:
During the past half-century, our species has embarked on a remarkable social experiment. For the first time in human history, great numbers of people - at all ages, in all places, of every political persuasion - have begun settling down as singletons. Until the second half of the last century, most of us married young and parted only at death. If death came early, we remarried quickly; if late, we moved in with family, or they with us. Now we marry later. We divorce, and stay single for years or decades.
The rise of living alone has produced significant social benefits, too. Young and middle-aged solos have helped to revitalise cities, because they are more likely to spend money, socialise and participate in public life. Contemporary solo dwellers in the US are primarily women: about 18 million, compared with 14 million men. The majority, more than 16 million, are middle-aged adults between the ages of 3S and 64. The elderly account for about 11 million of the total. Young adults between 18 and 34 number increased more than 5 million, compared with 500,000 in 1950, making them the fastest-growing segment of the solo-dwelling population.
Despite fears that living alone may be environmentally unsustainable, solos tend to live in apartments rather than in big houses, and in relatively green cities rather than in car-dependent suburbs. There's good reason to believe that people who live alone in cities consume less energy than if they coupled up and decamped to pursue a single-family home.

Which statement is probably TRUE according to the information in paragraph 1?
