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.

For which of the following reasons can natural pollutants play an important role in controlling air pollution ?

Read the following passage and choose the best answer (A, B, C, D):
Of all modern instruments, the violin is apparently one of the simplest. It consists in essence of a hollow, varnished wooden sound box, or resonator, and a long neck covered with a figerboard, along which four strings are stretched at high tension. The beauty of design, shape, and decoration is no accident: the proportions of the instrument are determined almost entirely by acoustical considerations. Its simplicity of appearance is deceptive. About 70 parts are involved in the construction of a violin. Its tone and its outstanding range of expressiveness make it an ideal solo instrument. No less important, however, is its role as an orchestral and chamber instrument. In combination with the larger and deeper- sounding members of the same family, the violins form the nucleus of the modern symphony orchestra. The violin has been in existence since about 1550. Its importance as an instrument in its own right dates from the early 1600s, when it fist became standard in Italian opera orchestras. Its stature as an orchestral instrument was raised further when in 1626 Louis XIII of France established at his court the orchestra known as Les vinq-quatre violons du Roy (The King's 24 Violins), which was to become widely famous later in the century. In its early history, the violin had a dull and rather quiet tone resulting from the fact that the strings were thick and were attached to the body of the instrument very loosely. During the eighteenth and nineteenth century, exciting technical changes were inspired by such composer-violinists as Vivaldi and Tartini. Their instrumental compositions demanded a fuller, clearer, and more brilliant tone that was produced by using thinner strings and a far higher string tension. Small changes had to be made to the violin's internal structure and to the figerboard so that they could withstand the extra strain. Accordingly, a higher standard of performance was achieved, in terms of both facility and interpretation. Left-hand technique was considerably elaborated, and new tigering patterns on the figerboard were developed for very high notes.

Mark the letter A, B, C, or D on your answer sheet to indicate the undelined part that needs correction in each of the following questions:
The mineral particles found in soil range in size from microscopic clay particles to large boulders. The most abundant particles - sand, silt, and clay - are the focus of examination in studies of soil texture. Texture is the term used to describe the line composite sizes of particles in a soil sample, typically several representative handfuls. To measure soil texture, the sand, silt, and clay particles are sorted out by size and weight. The weights of each size are then expressed as a percentage of the sample weight.
In the field, soil texture can be estimated by extracting a handful of sod and squeezing the damp soil into three basic shapes; cast, a lump formed by squeezing a sample in a clenched fist; thread, a pencil shape formed by rolling soil between the palms; and ribbon, a flatfish shape formed by squeezing a small sample between the thumb and index finger. The behavioral characteristics of the soil when molded into each of these shapes, if they can be formed at all, provides the basis for a general textural classification. The behavior of the soil in the hand test is determined by the amount of clay in the sample. Clay particles are highly cohesive, and when dampened, behave as a plastic. Therefore the higher the clay content in a sample, the more refined and durable the shapes into which it can be molded.
Another method of determining soil texture involves the use of devices called sediment sieves, screens built with a specified mesh size. When the soil is filtered through a group of sieves, each with a different mesh size, the particles become grouped in corresponding size categories. Each category can be weighed to make a textural determination. Although sieves work well for silt, sand, and larger particles, they are not appropriate for clay particles. Clay is far too small to sieve accurately; therefore, in soils with a high proportion of clay, the fine particles are measured on the basis of their settling velocity when suspended in water. Since clays settle so slowly, they
are easily segregated from sand and silt. The water can be drawn off and evaporated, leaving a residue of clay, which can be weighed.

During the procedure described in paragraph 3, when clay particles are placed into water they     ..

Butterflies are among the most extensively studied insects - an estimated 90 percent of the world's species have scientific names. As a consequence, they are perhaps the best group of insects for examining patterns of terrestrial biotic diversity and distribution. Butterflies also have a favorable image with the general public. Hence, they are an excellent group for communicating information on science and conservation issues such as diversity.
Perhaps the aspect of butterfly diversity that has received the most attention over the past century is the striking difference in species richness between tropical and temperate regions.
For example, in 1875 one biologist pointed out the diversity of butterflies in the Amazon when he mentioned that about 700 species were found within an hour's walk, whereas the total number found on the British islands did not exceed 66, and the whole of Europe supported only 321. This early comparison of tropical and temperate butterfly richness has been well confirmed. A general theory of diversity would have to predict not only this difference between temperate and tropical zones, but also patterns within each region, and how these patterns vary among different animal and plant groups. However, for butterflies, variation of species richness within temperate or tropical regions, rather man between them, is poorly understood. Indeed, comparisons of numbers of species among the Amazon basin, tropical Asia, and Africa are still mostly "personal communication" citations, even for vertebrates, In other words, unlike comparison between temperate and tropical areas, these patterns are still in the documentation phase.
In documenting geographical variation in butterfly diversity, some arbitrary, practical decisions are made. Diversity, number of species, and species richness are used synonymously; little is known about the evenness of butterfly distribution. The New World butterflies make up the preponderance of examples because they are the most familiar species. It is hoped that by focusing on them, the errors generated by imperfect and incomplete taxonomy will be minimized.

The idea “little is known about the evenness of butterfly distribution” in paragraph 5 is that     .

Read the passage carefully and choose the correct answer

I was born to dance. I've been dancing all my life, ever since my mother, who gave up a dancing career on the stage when she married my father, picked me up and twirled me around as an infant. As much as I loved dancing with her, her greatest gift to me was her “unconditional love” during her lifetime.

My parents divorced after only 5 years of marriage, but my father remarried a lovely lady who also loved to dance. They used to take me to a dancing club where I would listen to the music and watch them dance-occasionally my step-mother, Mary, invited me to dance.

I also met my wife, Charlotte, in a dancing party. I danced with her for about 15 minutes, and during that brief span, I realized that I fell in love with her. We kept dancing throughout our marriage. My earliest memories of dancing with my daughters started when I came home from work to our small home in Marblehead, Massachusetts, and my daughter Laura was about 3 years old. It was very relaxing for me to turn on the record player, pick up Laura in my arms, and dance her around the room!

Our family danced a lot. My daughters, Laura and Anne, and I continued to dance on every occasion. One favorite memory I have of dancing with Laura and Anne was when I took each of them when they were seniors in high school to the Daddy-Daughter dance. We won both dance competitions!

As their father, I have tried to provide my daughters with unconditional love, as my Mother provided to me, endless emotional and loving support, and good educations and life experiences which have helped prepare them for happy and successful adult lives. Being a father who is worthy of their love and respect, I consider fatherhood a privilege, not an entitlement.

In 1994, my oldest daughter Laura gave me a lovely book, which I still have, entitled “Fathers and Daughters.” My Father’s Day suggestion to every father is to dance with your daughters at every opportunity. It will not only bring you closer, it will give them memories of you “to hang onto” long after we are gone.

Helpful Home Remedies
When something is bothering us, it is natural to try and make it go away. We might head to the doctor or make a trip to the local pharmacy for medicine. Unfortunately, these methods can be time-consuming and expensive. But have no fear, because you might be able to whip up an effective home remedy with nothing more than a few simple ingredients from your cupboard. At one time or another, it seems everyone comes down with flu. Our temperature will rise, we may feel nauseous, and we will likely have a stuffy nose and a cough. Aside from taking it easy and getting plenty of rest, you can turn to chicken soup to make you feel better. Mothers from around the world have been making it for thousands of years for sick relatives. The hot soup warms you up and its flavorful smell helps to clear up your nose. It is often prepared with garlic, onions, and carrots which all provide vitamins that increase circulation and reduce inflammation. In addition, the liquid will keep you hydrated. Last but not least, it is usually delicious. Nothing drives people mad quite like getting the hiccups. If you are fortunate, they will only last for a few minutes. Yet in some cases, nothing seems to drive them away. Next time you have a bad case of the hiccups, try this sweet solution. Take a full teaspoon with sugar and swallow it down. The sugar is thought to change instructions to your nerves and get your throat muscles to relax. Just don’t overdo it, or else you might have to go to the dentist to get some cavities fixed. Headaches are another annoyance that we can do all without. If you get one, try this home remedy which doesn’t require taking any food or liquids at all. Instead, try putting a pencil in between your teeth. A major cause of headache is stress, and when we are anxious, we often tighten our jaws, which strains a muscle that connects to the temples of our head, and this action causes the pain. By placing a pencil in our mouths, we are giving our minds a signal to relax our jaw. This can reduce the intensity of headaches almost immediately. Just remember not to bite down, unless you are in the mood for a lead sandwich.
