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:
An air pollutnt is defined as a compound added directly or indirectly by humans to the atmosphere in such quantities as to affect humans, animals, vegetation, or materials adversely. Air pollution requires a very flexible definition that permits continuous change. When the first air pollution laws were established in England in the fourteenth century, air pollutants were limited to compounds that could be seen or smelled – a far cry from the extensive list of harmful subtances known today. As technology has developed and knowledge of the health aspects of various chemicals has increased, the list of air pollutants has lengthened. In the future, even water vapor might be considered an air pollutant under certain conditions.
Many of the more important air pollutants, such as sulfur oxides, carbon monoxide, and notrigen oxides, are found in nature. As the Earth developed, the concentration of these pollutants was altered by various chemical reactions; they became components in biogeochemical cycles. These serve as an air purification scheme by allowing the compounds to move from the air to the water or soil. On a global basis, nature’s output of these compounds dwarfs that resulting from human activities.
However, human production usually occurs in a localized area, such as as city. In such a region, human output may be dominant and may temporarily overload the natural purification scheme of the cycles. The result is an increased concentration of noxious chemicals in the air. The concentrations at which the adverse effects appear will be greater than the concentrations that the pollutants would have in the absence of human activities. The actual concentration need not be large for a subtance to be a pollutant; in fact, the numerial value tells us little until we know how much of an increase this represents over ther concentration that would occur naturally in the area. For example, sulfur dioxide has detectable health effects at 0.08 parts per million (ppm), which is about 400 times its natural level. Carbon monoxide, however, has a natural level of 0.1 ppm and is not usually a pollutant until its level reaches about 15 ppm.

Wolfgang Amadeus Mozart

Wolfgang Amadeus Mozart’s was the only surviving son of Leopold and Maria Pertl Mozart. Leopold was a successful composer, violinist, and assistant concertmaster at the Salzburg court. Wolfgang's mother, a constantly ill housewife, was born to a middle-class family of local community leaders. His only sister was Maria Anna. With their father’s encouragement and guidance, they both were introduced to music at an early age. Leopold started Anna on the keyboard when she was seven, as three-year-old Wolfgang looked on. Mimicking her playing, Wolfgang quickly began to show a strong understanding of chords, tonality, and tempo. Soon, he too was being tutored by his father.

Leopold was a devoted and task-oriented teacher to both his children. He made the lessons fun, but also insisted on a strong work ethic and perfection. Fortunately, both children excelled well in these areas. Recognizing their special talents, Leopold contributed much of his time to their education in music as well as other subjects. Wolfgang soon showed signs of excelling beyond his father's teachings with an early composition at age five and demonstrating outstanding ability on harpsichord and the violin. He would soon go onto play the piano, organ and viola.

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.

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.

Plants that Can Help You
We have already talked about some dangerous plants, but we don’t want to give anyone the wrong idea. Please don’t think that most plants are dangerous. The truth is that although some plants can hurt you, most are completely harmless. In fact, there are plenty of plants that are actually very useful to humans. That is why plants are so popular in Chinese medicine. Chinese medicine has been using plants for at least 4,800 years. One of the most popular plants in Chinese medicine is ginseng. Doctors of Chinese medicine believe that ginseng can help your lungs, clean your blood, and do many other things. Ginseng is also a source of energy. In fact, many modern energy drinks that you see in stores contain ginseng. In some parts of the US, there is a plant called lady fern. This is the plant you need if you have been stung by a bee, or if you have got a small burn or a cut. Lady ferns are great for making your skin feel better. All you have to do is roll one of its leaves and crush it in your hands. The juices inside the leaf will help your skin feel better. If you are ever hiking in Europe, look for a flower called tansy. This yellow flower is a natural insect repellent. You just rub it on your skin, and insects will leave you alone. Sage is one of the most useful plants in the world. Because it has so many uses, it is also quite valuable. Human beings have been using sage for a very long time. In Europe, before refrigerators existed, people often used sage to preserve food. Over the years, people have used sage to fight all kinds of health problems. Sage has been used to treat colds, stop muscle problems, and reduce swelling. There are all kinds of other things that people have used sage for. In fact, sage is so useful that it comes from the Latin word “salvere” which means “to be saved”.

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.
