Flying Drones into Danger Zones
A plane is sent deep into the enemy territory with a deadly mission. It is assigned to eliminate several key targets with a precision bombing campaign. This mission won’t be easy, however, as to be successful, the plane will have to avoid enemy rockets and tank fire. There will be no risk to the life of the “pilot” of the plane because he will not be able to aboard the vessel. Instead, he will be thousands of miles away inside a control tower, as he is operating a drone. Drones, which are also called UVAs or unmanned aerial vehicles, marked a major step forward in technology. Inventors have been working on them since the early 1900s. Although some devices were designed back then, they weren’t able to do much more than a standard model airplane. In fact, it was not until a US plane was shot down in 1959 during the Cold War that the US military really got serious about drones. The aim was to save pilots’ lives while flying over hazardous territories. Drones usually fall into two categories. The first type of drones relies on human control from a remote location. The second type of drones is pre­programmed with computer instructions, and it then completes its mission operating autonomously. In addition to protecting pilots’ lives, drones also have several other advantages. They can stay in the air for longer periods of time because there is no concern for eating, sleeping, or rest breaks that pilots typically require. Drones can also be produced cheaper since manufacturers don’t need to value safety precautions as they would for aircraft flown by humans. Despite their usefulness, military drones have been the cause of great criticism over the past decade. There have been cases of British and American drones missing their targets and killing innocent civilians instead. The Brookings Institution released a statistic that for every military leader who is killed by a drone strike, ten civilians die. Some suggest that if human pilots were flying these planes, they wouldn’t have made these errors. Drones don’t always have targets that they must eliminate. The military also employs special surveillance drones that use long-range cameras to gather information about buildings, enemy soldier formations, and other vital information from the ground. In the end, whether people are for or against the use of drones, it appears that they are certain here to stay.

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:
Composers today use a wider variety of sounds than ever before, including many that were once considered undesirable noises. Composer Edgard Varese (1883-1965) called thus the “liberation of sound…the right to make music with any and all sounds.” Electronic music, for example – made with the aid of computers, synthesizers, and electronic instruments – may include sounds that in the past would not have been considered musical.
Enviromental sounds, such as thunder, and electronically generated hisses and blips can be recorded, manipulated, and then incorporated into a musical composition. But composers also draw novel sounds from voices and non-electronic instruments. Singers may be asked to scream, laugh, groan, sneeze, or to sing phonetic sounds rather than words. Wind and string players may lap or scrape their instruments. A brass or woodwind player may hum while playing, to produce two pitches at once; a pianist may reach inside the piano to pluck a string and then run a metal blade along it. In the music of the Western world, the greatest expansion and experimentation have involved percussion instruments, which outnumber strings and winds in many recent compositions. Traditional persussion instruments are struck with new types of beaters; and instruments that used to be couriered unconventional in Western music – tom-toms, bongos, slapsticks, maracas – are widely used.
In the search for novel sounds, increased use has been made in Western music of Microtones. Non-Western music typically divides and intervals between two pitches more finely than Western music does, thereby producing a greater number of distinct tones or micro tones, within the same interval. Composers such as Krzysztof Penderecki create sound that borders on electronic noise through tone clusters – closely spaced tones played together and heard as a mass, block, or band of sound. The directional aspect of sound has taken on new importance as well Loudspeakers or groups of instruments may be placed at opposite ends of the stage, in the balcony, or at the back and sides of the auditorium. Because standard music notation makes no provision for many of these innovations, recent music scores may contain graph like diagrams, new note shapes and symbols, and novel ways of arranging notation on the page.

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.

It can be inferred from the passage that the sediment sieve has an advantage over the hand test in determining soil texture because         .

For hundreds of years, giving flowers have been a social means of communication. In the United States, flowers are often given during rites of passage, for commemorating special occasions or as a heartfelt gift between loved ones and friends. Flower gifting also occurs in most countries around the world. However, the meanings and traditions often vary. While students traditionally gave their favorite teacher an apple in past years, in China, teachers are given flowers. Peonies are by far the flower most often given in China. They are also quite popularly used for weddings. Strangely, potted plants are not considered a pleasant gift among Asian cultures. The people believe that like a plant confined by a pot, the gift symbolizes a binding or restriction. In Russia, in lieu of giving birthday presents, the guest of honor receives a single flower or an unwrapped bouquet. Floral arrangements or baskets are not given. Russians celebrate a holiday known as Woman's Day. Traditional gifts include red roses, hyacinths or tulips. When there is a funeral or other occasion where someone wishes to express sympathy, carnations, lilies or roses are given in circular configurations, which signify the transition of birth, life and death to rebirth. In this instance, the color of choice is commonly yellow. For joyous occasions, arrangements and bouquets generally contain an odd number of flowers. In the times of ancient Rome, brides carried flowers to scare away evil spirits and encourage fertility. The Dutch believed that flowers were food for the soul. When invited to someone's home in Great Britain, it is tradition to bring a gift of flowers. All types are acceptable except white lilies, which are usually seen at funerals. Unlike the United States, red roses are a symbol of love. Flowers are generally gifted in odd numbered increments regardless of the occasion. However, the British also have superstitions regarding the number 13, so the number is avoided.

Don’t Handle with Care
People always go shopping for the latest and greatest gadgets. Speed, performance, and the latest functions are always key factors before making a purchase. Yet the most important factor of all, which often isn’t considered, is a product’s durability. After all, if a product breaks easily and can’t be repaired, the buyer will have wasted their investment. In other cases, weakly-designed product can cost someone their life. Thankfully, today’s inventors and engineers coming up with some incredible ways to ensure that many products can survive the most difficult situations. One area where durability is absolutely essential is in designing weaponry. In the industry, lapses in quality can lead to death. Designers of military vehicles have recently made great strides in creating some extra tough bulletproof vehicles. Researchers were inspired by the advances made with a similar technology, bulletproof vests. This equipment, which keeps police officers and soldiers protected from gunfire, has been continually upgraded as time has gone on. In order to get tougher, these vests have got lighter, so officers and soldiers can move more freely while working. Beautiful screens, a fast computer processor, and the latest software are probably the biggest concerns for most people shopping for new smartphones. Yet, since most mobiles will be subject to their fair share of bumps and bruises during their life cycle, durability should also be a major concern. A major breakthrough in recent years was the invention of Gorilla Glass. This technology not only prevents devices from breaking when dropped on hard surfaces, but it also makes them scratch-resistant as well. Gorilla Glass screens are given molten alkaline salt baths that produce a hard, compressed layer at the surface. Before a screen can crack, it will have to penetrate this rugged surface, which takes a large degree of force. Recently, another new technique called electrospinning was developed that could make future products even tougher to break. The process involves applying high voltage to a polymer to create a strand of nanofiber. Products designed with the material will be able to absorb more energy without breaking. Researchers are aiming to lighten up aircraft and potentially decrease the damage planes suffer in crashes. Hopefully, these advances are just the beginning. Although science has come a long way in helping manufacturers to create more durable products, the next century should surely bring some even more incredible improvements.
