Read the following passage and choose the best answer (A, B, C, D):
Prehistoric mammoths have been preserved in the famous tar pits of Rancho La Brea (Brea is the Spanish word for tar) in what is now the heart of Los Angeles, California. These tar pits have been known for centuries and were formerly mine for their natural asphalt, a black or brown petroleum-like substance. Thousands of tons were extracted before 1875, when it was first noticed that the tar contained fossil remains. Major excavations were undertaken that established the significance of this remarkable site. The tar pits were found to contain the remains of scores of species of animals from the last 30,000 years of the Ice Age. Since then, over 100 tons of fossils, 1.5 million from vertebrates, 2.5 million from invertebrates, have been recovered, often in densely concentrated tangled masses. The creatures found range from insects and birds to giant ground sloths, but a total of 17 proboscideans (animals with a proboscis or long nose) - including mastodons and Columbian mammoths - have been recovered, most of them from Pit 9, the deepest bone-bearing deposit, which was excavated in 1914. Most of the fossils date to between 40,000 and 10,000 years ago. The asphalt at La Brea seeps to the surface, especially in the summer, and forms shallow puddles that would often have been concealed by leaves and dust. Unwary animals would become trapped on these thin sheets of liquid asphalt, which are extremely sticky in warm weather. Stuck, the unfortunate beasts would die of exhaustion and hunger or fall prey to predators that often also became stuck. As the animals decayed, more scavengers would be attracted and caught in their turn. Carnivores greatly outnumber herbivores in the collection: for every large herbivore, there is one saber-tooth cat, a coyote, and four wolves. The fact that some bones are heavily weathered shows that some bodies remained above the surface for weeks or months. Bacteria in the asphalt itself would have consumed some of the tissues of other than bones, and the asphalt itself would dissolve what was left, at the same time impregnating and beautifully preserving the saturated bones, rendering them dark brown and shiny.

The Magical Mind of Leonardo Da Vinci
When someone shows great skills in a certain field, we call them a genius. In particular, the term is most associated with two people. One is the famed scientist Albert Einstein, and the other is Leonardo Da Vinci. However, unlike Einstein, whose achievements were essentially all related to science, Leonardo Da Vinci was a master at art, architecture, invention, and several other areas. Da Vinci was bom in Italy in 1452. He took to art at an early age and at age 14, he went to study as an apprentice in Florence under the artist Verrocchio. For the next six years. Da Vinci picked up drawing, carpentry, sculpting, and many other techniques from his master and his talent was evident. In fact, Da Vinci was such a good painter that his talent frustrated his master. Eventually, Verrocchio was so frustrated by his student’s genius that he stopped painting altogether. By the age of 20, Da Vinci was considered a master artist and set up his own workshop. It was there that Da Vinci was approached to create a painting for the Duke of Milan. The Duke was so impressed by his work that he would bring him under his service. In addition to creating paintings and sculptures, the Duke also had him design innovative buildings, machines, and weapons. Da Vinci would draw up plans for several futuristic inventions including tanks, submarines, and flying machines. He also mastered the art of drawing every muscle and detail of the human body. The only criticism one could make of Da Vinci is that his brilliant mind jumped so quickly from subject to subject that he rarely completed the works he started. The ones he did finish were often spectacular masterpieces, such as his paintings The Last Supper and the timeless Mona Lisa. The latter, which is on display at the Louvre in Paris, is arguably the most famous painting of all times because of its incredible detail and realism. Although Da Vinci died in 1519, his effect on the art world has never waned. He helped coin the term “Renaissance man” which refers to someone who excels in many different areas. Perhaps the greatest present Da Vinci left behind was his journals. Admirers and students of his work can examine 13,000 pages of his notes, drawings, and ideas to better understand what made this genius tick.
1. How is Einstein different from Da Vinci?

Incredible Shrinking Microchips
There is a popular old saying that “bigger is better”. Although this may be true in some regards, the exact opposite often applies in technology. As electronic components get smaller, it allows companies to manufacture tinier devices with more features. Thus began the never-ending quest to create the smallest microchips on the planet. Yet as these vital electronic components get smaller, they are also getting stronger and clever inventors are finding new ways in which to use them to do incredible things. Currently, the biggest limitation microchip producers face when trying to reduce chips’ size is the copper wires that provide electrical current throughout the chip. Although they can be made smaller, this can cause a whole host of problems such as melting and overheating. Thanks to the work of a few scientists from the UK though, this problem may soon be a thing of the past. Their solution is getting rid of the copper wiring altogether and using carbon nanotubes instead. Not only would this allow for smaller sizes but it would also increase the power that microchips can generate. In the end, this would translate into smaller and more powerful devices much to the delight of consumers all over the world. Corporate powerhouse Intel® has announced plans to create a line of tiny, low power chips that can be used in bracelets, smart watches, and other tiny devices. The chips will be called Intel® Quark, and they are being designed primarily to fit in biomedical devices. A key selling point to biomedical technology is that the devices have to be nonintrusive because people don’t want to carry around heavy equipment to monitor their health. If they can do this, Intel® will likely find several tablet and smartphone manufacturers who are willing to corporate Quark microchips into their devices. In a somewhat unusual project, researchers are working on a special microchip that will serve as miniature human organs in experiments. These “organ” chips could be used to test different medicines and study diseases. If realized, the technology could put an end to the use of lab mice and other animals for testing. Everyone from the largest pharmaceutical companies to the US military has shown interest in the project. Currently, the research team in charge of the project believes that within five years the organ chips will be used in practical research. It goes to show that thinking small often produces the biggest results.

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 lack of printing regulations and the unenforceability of British copyright law in the American colonies made it possible for colonial printers occasionally to act as publishers. Although they rarely undertook major publishing project because it was difficult to sell books as cheaply as they could be imported from Europe, printers in Philadelphia did publish work that required only small amounts of capital, paper, and type. Broadsides could be published with minimal financial risk. Consisting of only one sheet of paper and requiring small amounts of type, broadsides involved lower investments of capital than longer works. Furthermore, the broadside format lent itself to subjects of high, if temporary, interest, enabling them to meet with ready sale. If the broadside printer would know this immediately, there would be no agonizing wait with large amounts of capital tied up, books gathering dust on the shelves, and creditors impatient for payment.
In addition to broadsides, book and pamphlets, consisting mainly of political tracts, catechisms, primers, and chapbooks were relatively inexpensive to print and to buy. Chapbook were pamphlet-sized books, usually containing popular tales, ballads, poems, short plays, and jokes, small, both in formal and number of pages, they were generally bound simply, in boards (a form of cardboard) or merely stitched in paper wrappers (a sewn antecedent of modern-day paperbacks). Pamphlets and chapbooks did not require fine paper or a great deal of type to produce they could thus be printed in large, cost-effective editions and sold cheaply.
By far, the most appealing publishing investments were to be found in small books that had proven to be steady sellers, providing a reasonably reliable source of income for the publisher. They would not, by nature, be highly topical or political, as such publications would prove of fleeting interest. Almanacs, annual publication that contained information on astronomy and weather patterns arranged according to the days, week, and months of a given year, provided the perfect steady seller because their information pertained to the locale in which they would be used.

What were “steady sellers”?

The Particle that Started the Big Bang
In 2013, the Nobel Prize for Physics was awarded to Francois Englert and Peter W. Higgs for their discovery of a particle that is vital to our understanding of the universe. Although its official name is the Higgs boson, many refer to it as the God particle, because it’s considered to be the building block of the universe. Many believe that the Higgs boson may be the cause for the Big Bang explosion which led to the creation of the universe. In the 1960s, Higgs came up with the concept that particles had no mass when the universe started. In a split-second, however, it came into contact with something that gave it mass. This, Higgs theorized, was the Higgs boson. Many scientists initially laughed at the idea, but in the upcoming years, Higgs along with Englert and several of their peers continued to work on these concepts. Their ideas would eventually help lead the way to the discovery of the Higgs boson decades later. The search for the Higgs boson certainly didn’t come up cheap, as it cost nearly $10 billion to build the machinery necessary to perform the tests to find it. Yet nearly every physicist would agree that it was worth it, as the Higgs boson has already been labeled as one of the most important discoveries in particle physics. The finding is also a huge boost for physics in general because it proves that the Standard Model of Physics which researchers have been using for years is correct. The Higgs was the last remaining question mark as all of the other particles and elements had been found. Still, many ordinary people may question how such a discovery affects their lives at all. Although quantum mechanics may seem weird, it has actually led to several important technological breakthroughs over the past century. These findings have led to laser and X-ray technologies that work in the real world. There is still much to be learned with further observation of the Higgs boson in action. Scientists hope to learn more about dark matter, a strange substance that constitutes 25 percent of the mass of the universe. The research could also lead to some other technologies as well.

The life of a Professional Gamer
Gordon Hayward has a pretty cool job – he plays basketball for the team Utah Jazz in the American National Basketball Association (NBA). But in his free time, he also works as a professional gamer, competing in StarCraft 2 tournaments. Even as a top – level athletes, Gordon is impressed with the amount of commitment needed for these competitions. “These guys are professionals”, he says. “They play this game for their job, so they take this as seriously as I take playing basketball for a living.” Competitive gaming has been around for almost as long as video games themselves, but it’s only recently that people have started earning money from it. This is because companies sponsor gamers, and tournaments. The gaming industry is now worth about $6 billion, and it is growing every year. Michel Masquelier, President of IMG Media (one of the world’s largest entertainment companies), called gaming the number one activity in the world for men aged 18 to 24. Just as young people aspire to play in the NBA, many also dream of becoming professional gamer. There are now big global tournaments like World Cyber Games and Major League Gaming Championships, where hundreds of gamers come to compete in popular game like StarCraft, WarCraft, Counterstrike, and the football game FIFA in front of an audience. The prize money in a tournament can reach a few million dollars. One thing gamer, and athletes have in common is that they often play in teams. These “clans”, as gamers call them, usually play tournaments together and practise against one another. Professional gamers and their clans earn money through sponsorships, winning tournament, and teaching and training people to play video games better. Like athletes, gamers must train long and hard to become the best at the game that they play. Most gamers only compete in one game, the same way that most professional athletes only play one sport. Adrian Kwong, a professional gamer, says that he usually practises StarCraft 2 for more than three hours a day. Some days he even plays for more than five hours. “To become a pro player, it takes determination, skill, and extensive practice,” says Katie Goldberg, who is vice – president of communications at Major’s League Gaming. Gordon Hayward isn’t going to give up his basketball career anytime soon, but he says that athletes and gamers are not that different: “You have to train hard if you want to be the best, and that goes for everything, not just basketball. That also goes for video games like StarCraft”.

Getting Closer to Nature at National Parks
In modern times, we seem to be getting more separate from nature with each passing day. Most of us spend the majority of our time indoors, typing away at computers and fiddling with digital devices. All the while, we are destroying the planet’s natural beauty by cutting down forests and building cities in their place. In an effort to preserve nature for future generations, national parks were created. The primary function of national parks is conservation. In many cases, it is a matter of national pride for countries to protect their indigenous species. Although several nations considered opening national parks, the US was the first country to officially do so when Yellowstone Park opened in 1872. This designation made the federal government responsible for taking care of the territory. Soon after, national parks started to open in Australia, New Zealand, Europe, and eventually across the globe. Today, almost 100 countries have established their own national parks. In total, there are over 6,500 worldwide. There are several incredible national parks that have a lot to offer. Kruger National Park in South Africa at 19,633 square kilometers is one of the largest game reserves. Tourists can go on safari and witness elephants, rhinoceroses, lions, and several other large mammals in their natural environments. At 75,000 square miles, the Northeast Greenland National Park is the world’s largest. In fact, it is larger than all but 30 countries in the world. Despite differences in names, location, and rules, most natural parks have certain traits in common. For one, they are usually open to visitors throughout the year. Those who come to the park can take part in a wide scope of outdoor activities including hiking, camping, cycling, bird watching, and fishing. Other options may include horseback riding, rafting, or scuba diving if the territory is suitable. In most places, visitors are encouraged not to feed the animals. The purpose for this law is twofold: to protect the animals as well as those who might feed them. Animals also have strict dietary needs, so feeding them exotic foods could make them sick. Feeding wild animals could also cause them to aggressively pester humans they encounter in the future for food. However, as long as you follow the rules, you are assured of having a great time at whichever national park you visit.

Read the following passage and choose the best answer (A, B, C, D):
The ubiquitous bar code, developed more than twenty years ago, is not a stagnant product. On the contrary, the technology has been improved so that it can be used more efficiently. Much less expensive than a computer chip, the bar code can hold more information than it had in the past by adding a second dimension to the structure. The bar code consists of a series of parallel vertical bars or lines of two different widths, although sometimes four widths are used, printed in black on a white background. Barcodes are used for entering data into a computer system. The bars represent the binary digits 0 and 1, just like basic computer language, and sequences of these digits can indicate the numbers from 0 to 9, which can then be read by an optical laser scanner and processed by a digital computer. Arabic numbers appear below the code. The traditional bar code has been used to monitor skiers at ski lifts and to determine price and perform inventory control on groceries, drugs, medical supplies, manufactured parts, and library books to name a few. The bar code used on grocery products, introduced in the 1970s, is called a universal product code (or UPC) and assigns each type of food or grocery product a unique code. The five digits on the left are assigned to a particular manufacturer or maker and the five digits on the right are used by that manufacturer to identify a specific type or mark of product. Traditional single dimension bar codes are not readily customizable because there is little extra space. The two-dimensional bar code, with an information density of 1,100 bytes, allows a considerably greater amount of information to be coded than does the traditional bar code, including customized information. [A] It also has built-in redundancy, meaning that the identical information is duplicated on the same code. [B] Therefore, if the code is damaged, it can still be read. [C] The technology even allows pictures or texts to be contained within the code, as well as bar code encryption. [D] The new technology dramatically reduces the errors of the single dimensional bar code and reduces the enormous costs that some companies have reported in the past. 
3. The author implies that the bar code:
