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. 
5. Where in the final paragraph ([A], [B], [C], or [D]) could the following sentence be logically placed? Thus, the manufacturer is able to add additional information on the bar code that it finds useful for its own tracking purposes

Are Human Beings Getting Smarter?
Do you think you are smarter than your parents or grandparents? According to James Flynn, a professor at a New Zealand university, you might be. Over the course of the last century, IQ test scores of people in some countries have got increasingly better - on average, three points better for every decade that has passed. This trend of improving scores is known as “the Flynn effect,” and scientists want to know what is behind it. IQ tests and other similar tests are designed to measure general intelligence rather than knowledge. Flynn knew that intelligence is partly inherited from our parents and partly the result of our environment and experiences, but the improvement in test scores was happening too quickly to be explained by heredity. So what happened in the 20th century that led to higher test scores? Scientists have proposed several explanations for the Flynn effect. Some suggest that the improved test scores simply reflect an increased exposure to tests in general. Because we take so many tests, we learn test-taking techniques that help us perform better. Others have pointed to better nutrition, which results in babies being born larger, healthier, and with more brain development than in the past. Another possible explanation is a change in educational styles - children are encouraged to discover things for themselves rather than just memorizing information. This could prepare people to do the kind of problem-solving that intelligence tests require. Flynn himself suggested that learning new technologies may have improved people’s problem-solving skills. This may be true for the first decade of his tests, when IQ scores in many countries increased. However, in recent years, IQ test scores in some countries have begun to decline. Data from Norway, the Netherlands, Australia, and Great Britain have shown that as these countries become more and more modern, IQ scores have begun to drop. While scientists aren’t sure what is causing this decline, they think technology is dramatically changing the way that we learn and get information. For example, people are now able to access all kinds of information easily using online resources like Google or Wikipedia. The danger is when they start to rely too much on these sources of information, and not do any thinking for themselves. Lifestyle changes that come with modem technology may also have a negative effect on intelligence, such as video games and television making people less social.  So while the world may have got smarter over the 20th century, improving technology and changing lifestyles may soon reverse that trend.

Read the following passage and choose the best answer (A, B, C, D):
During the nineteenth century, women in the United States organized and participated in a large number of reform movements, including movements to reorganize the prison system, improve education, ban the sale of alcohol, and, most importantly, free the slaves. Some women saw similarities in the social status of women and slaves. Women like Elizabeth Cady Stanton and Lucy Stone were feminists and abolitionists who supported the rights of both women and blacks. A number of male abolitionists, including William Lloyd Garrison and Wendell Philips, also supported the rights of women to speak and participate equally with men in antislavery activities. Probably more than any other movement, abolitionism offered women a previously denied entry into politics. They became involved primarily in 20 order to better their living conditions and the conditions of others. When the Civil War ended in 1865, the Fourteenth and Fifteenth Amendments to the Constitution adopted in 1868 and 25 1870 granted citizenship and suffrage to blacks but not to women. Discouraged but resolved, feminists influenced more and more women to demand the right to vote. In 1869, the Wyoming Territory had yielded 30to demands by feminists, but eastern states resisted more stubbornly than before. A women's suffrage bill had been presented to every Congress since 1878 but it continually failed to pass until 1920, 35 when the Nineteenth Amendment granted women the right to vote.

It’s in Your Genes
Every human being has about 25,000 genes. Your genes are part of your DNA. They give your body instructions on how to develop. For example, if your genes tell your body to build long, thin fingers, then you will have long, thin fingers. Your genes come from your parents, and they decide everything about you. They decide your hair colour, your eye colour, your height, and so on. Genes are still a bit of a mystery to scientists, but they are learning new things about them all the time. One issue that people often debate is this: Do our genes influence our personalities? These days, most people agree that the answer to this question is yes. Recent studies have shown that genes especially influence our self-control and our sense of purpose. Your sense of purpose is your desire to have goals in your life. If a person really wants to accomplish something and do well in life, he or she has a sense of purpose. A person who does not care about goals has no sense of purpose. Although scientists agree that our genes influence our personalities, there is another question. How much do they influence us? Can we control ourselves, or do our genes control us? People everywhere are still debating this issue. So far, we don’t really have an answer. Genes also affect your health. If a gene has a problem, it is called a mutated gene. Some mutated genes can cause diseases. That is why if a person has a certain health problem, his or her child is more likely to have that same problem. The child also has the mutated gene. As scientists and doctors learn more about genes, they are also developing a new kind of medicine: gene therapy. Therapy is help for a mental or a physical problem. Gene therapy means fixing or replacing mutated genes. Scientists are still experimenting on gene therapy. It is possible that in the future, gene therapy will help doctors prevent and cure diseases that are caused by mutated genes.

The LED Lighting Revolution
If you have picked up any electronics magazines recently, you have probably heard about LEDs; yet chances are, you probably don’t realize why they are so special. The truth is that these tiny light bulbs are helping to improve watches, remote controls, televisions, and a host of other projects. Diodes are components that enable energy to flow in one direction, while simultaneously blocking the current from the opposite direction. This is similar to how a valve works on a faucet. If electronic manufacturers require currents to flow in several directions, then multiple diodes will be included in the circuit design. With LEDs, every time a current passes through them, a light is emitted. LED is short for light-emitting diode. Although they have only recently waves in the past decade or so, early models have been around since 1962. There are several benefits that LEDs offer when compared to incandescent or fluorescent lighting. For starters, they have extremely long-life spans in the range of l00,000 hours even in the toughest conditions. They also require far less energy than power sources, which can save users money over the long run. Since LEDs don’t contain moving parts like other bulbs, they can withstand heavy impacts without getting damaged. Finally, they don’t require any _warm-up time_ so they instantly light up when switched on. The only drawback is that they are still a more expensive to purchase at the moment. LEDs were first used on digital clocks, but they have come a long way since then. They have certainly done a lot to improve TV technology. LED TVs have been a hit because they can be built extremely thin, yet also offer power-saving benefits. LED TVs also provide a wider range of colour, which allows for more lifelike and vivid images. In the future, organic LEDs, or OLEDs, will bring additional benefits for viewers. OLEDs are even more flexible than LEDs, so manufacturers will be able to create bent display screens and lights. Therefore, you will be able to roll up your living room TV set and pack it in your suitcase. In other words, LED and OLED technology will likely be lighting up your life for years to come.

No More Polar Bears?
We all know that the Earth is getting warmer and warmer. This problem is called “global warming”. We also know that global warming is causing a lot of problems. Ocean levels are getting higher and higher. Because ocean levels are getting higher, storms are getting stronger and stronger. This list of problems goes on and on. Animals are suffering a lot because of global warming. Polar bears are suffering more than most animals. This is because polar bears live in the North Pole. In the North Pole, global warming is making ice melt. Polar bears hunt from large pieces of floating ice. They jump off the ice and hunt for food. Polar bears have to swim and find these floating pieces of ice. These days, they have to swim farther to find the floating ice. Many of them don’t have enough energy. They get too tired, and they die in the water. Polar bears are suffering because of other problems, too. Pollution makes their water dirty. Many countries go to the North Pole to look for oil and gas, and they damage the environment of the bears. In addition, when ships sail through the North Pole, they cause a lot of damage. Finally, people hunt and kill too many polar bears. However, melting ice is definitely the biggest problem. Right now, there are about 25,000 polar bears in the world. If global warming continues, there may be only about 12,000 in the year 2050. By the year 2080, that number might be much smaller. It is important to study polar bears. When we learn about polar bears, we also learn about the health of the North Pole. If polar bears are doing well, then the environment in the North Pole is probably healthy. If polar bears are suffering then there are probably serious problems in the North Pole. Right now, governments around the world are working to help polar bears. There are new laws that protect polar bears. However, if global warming continues to get worse, polar bears may disappear forever.

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.

Piranhas on Parade
With the exception of whales and sharks, fish are generally considered to be harmless creatures. The thought of a small fish hurting anyone is almost laughable. However, piranhas are an exception to this rule. They frequently attack in groups and in some cases they can cause great bodily harm. Most piranhas are under 25 centimetres long, but don’t let their size fool you. Unlike most fish, they have two rows of razor-sharp teeth. Their triangular shape makes them perfect for puncturing and shredding whatever they bite. Although piranhas usually swim alone, they also hunt in school of 1,000 fish or more, which greatly multiplies the damage they are capable of. As small fry, they feed of vegetables and plankton until they can tolerate meat. In terms of flesh, they will eat any animals or fish that enters their territory when swimming in schools, even humans. In some cases, hungry piranhas will even go after each other if they are really desperate for a snack. However, the danger they present to humans is often exaggerated. In Hollywood films, piranhas are often portrayed as vicious destroyers who love to eat people. Some rumours even developed that schools of hungry piranhas will quickly kill and consume humans in a matter of seconds. In reality, the majority of these attacks only consist of a few painful, but non-life threatening bites to the person. However, that is not always the case. A recent attack on December 25, 2013 in Argentina left at least 60 people injured. Victims were wading in a river when a sudden attack began. Local police believe that some local debris left floating by fishermen brought the piranhas to the area. Many swimmers left the water with cuts all over their bodies, and a few even had to have their limbs amputated. Oddly enough, some people choose to keep piranhas in their home aquariums. However, piranhas can be tough to catch for this purpose because their sharp teeth can easily cut through fishing nets. Before buying one, be sure to check local laws as it is illegal to own them in many areas. Lawmakers often fear of the damage piranhas can cause to marine life if an owner decides to release them into a local stream.
7. According to the passage, why is it illegal to own piranhas?
