Read the following passage and choose the best answer (A, B, C, D):
Genetics is the study of hereditary characteristics that are passed down from one generation of living organisms to another. Although farmers have used selective breeding to improve the resilience of crops and animals, it wasn't until the mid-1800s that Gregor Mendel started the science of genetics as we know it today. Following Mendel's methods, scientists have discovered "chromosomes" and "DNA". With the ability to study DNA, scientists were able to study the genetic differences between races. Modern genetics discovered that all humans are descendants of "Mitochondrial Eve," a woman who lived over 150,000 generations have passed, and many subtle differences are now evident. Humans share at least 99% of their genetic makeup. A 1% difference may not seem like much, but when you consider that a chimpanzee shares 98% of human genes, you realize how much a 1% difference makes! Africans are more closely related to Europeans than any other two groups despite the fact that they differ so much in appearance. The biggest genetic differences are found between Africans and the native populations of Nord America (22%). However, it is essential to note that the genetic differences between people of the same race are much greater than the differences between people of different races. This means that the argument which claims that genets differences make one race superior to another is nothing but a tall story. The differences in various populations may also be the result of circumstances rather than genetic makeup. Factors such as climate, diet, health care, education, and employment as well as other socioeconomic factors are all influential. However, there are some traits which are genetic, for example, then is a much higher incidence of sickle cell anemia among black populations that any other population group. Adult African-Americans and Latinos have twice as many cases of diabetes than Caucasians. In the U.S, Latinos suffer more deaths from liver disease than other races. Europeans suffer more from heart disease and cancer. Genes not only affect our susceptibility to disease, they also affect our physical attributes. The Dinka people from the Sudan are considered to be the tallest people with men having an average height of 6ft 3 in, while women hit the big time with an impressive 5ft 3 in. This contrasts sharply with the Pygmy tribes who get the short end of the stick at only about 4ft 11 in tall. Genetic differences may help US to tailor health service to people of different races or to detect life threatening diseases early. However, they are not significant enough to support the claim that one race is superior to another. In fact, our modern scientific understanding of human genetic diversity flit in the face of almost all our social stereotypes.

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.

Putting Cars on Autopilot
Automobile accidents are one of the leading causes of death each year. Accidents can occur due to drunk driving, mechanical problems, carelessness, or a whole assortment of other reasons. In the near future, these problems could be solved by eliminating the person behind the wheel. Driverless cars may soon be turning all vehicle owners into “backseat drivers”. Driverless cars are vehicles that use several technologies to operate without human input. Through GPS, they can find a location on a map and plan the best route to get there. They may also use radar to detect other vehicles and avoid them when necessary. One company involved with developing driverless cars is Google. It’s developing a software called Google Chauffer which powers the vehicles. The technology isn’t cheap though, as Google robotic cars contain about $150,000 worth of equipment. In 2012, Google began testing the cars on the road with a highly-skilled driver in the driver’s seat, and a Google engineer in the passenger seat. In case there are any malfunctions, the human driver can step on the brakes or turn the wheel to take control of the automobile. Other car manufacturers are also working on implementing automated options into their cars. For example, the 2014 Mercedes-S class offers advanced cruise control using radar, lane warnings, and even detects, and warns drivers when they appear tired. Many Americans seem open to the idea, as three states have already passed laws that make it legal for driverless cars to be on the road. Still there will be some stumbling blocks to overcome before the roads are controlled by digital decision-makers. Firstly, companies will need to provide proof that driverless cars were tested a lot and are truly safe. Automobile manufacturers will also have to find a way to bring down costs, as few people would be able to afford the equipment required. Driverless cars could also potentially become targets for computer hackers. If a hacker were somehow able to override the software system, they could cause accidents or malfunctions. There are also economic issues to consider. If driverless cars became successful, millions of truck, bus, and taxi drivers would likely lose their jobs. Despite these issues, all indications suggest that it should be just a matter of time before humans are no longer needed behind the wheel.
4. Why does the author suggest that Americans are OK with the concept of driverless cars?

Read the following passage and choose the best answer (A, B, C, D):
One of the major problems in the art world is how to distinguish and promote an artist. In effect, a market must be created for an artist to be successful. The practice of signing and numbering individual prints was introduced by James Abbott McNeill Whistler, the nineteenth-century artist best known for the painting of his mother, called "Arrangement in Grey and Black", but known to most of US as "Whistler's Mother". Whistler's brother-in- law, Sir Francis Seymour Haden, a less well-known artist, had speculated that collectors might find prints more attractive if they knew that they were only a limited number of copies produced. By signing the work in pencil, an artist could guarantee and personalize each print. As soon as Whistler and Haden began the practice of signing and numbering their prints, their work began to increase in value. When other artists noticed that the signed prints commanded higher prices, they began copying the procedure. Although most prints are signed on the right-hand side in the margin below the image, the placement of the signature is a matter of personal choice. Indeed, prints have been signed within the image, in any of the margins, or even on the reverse side of the print. Wherever the artist elects to sign it, a signed print is still valued above an unsigned one, even in the same edition.
3. What made Whistler's work more valuable?

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.
