In our connected globalized world, the languages which dominate communications and business, Mandarin, Hindi, English, Spanish and Russian amongst others, are placing small languages spoken in remote places under increasing pressure. Fewer and fewer people speak languages such as Liki, Taushiro and Dumi as their children shift away from the language of their ancestors towards languages which promise education, success and the chance of a better life. While to many parents, this may appear a reasonable choice, giving their offspring the opportunity to achieve the sort of prosperity they see on television, the children themselves often lose touch with their roots. However, in many places the more reasonable option of bilingualism, where children learn to speak both a local and a national language, is being promoted. This gives hope that many endangered languages will survive, allowing people to combine their links to local tradition with access to wider world culture. 
While individuals are free to choose if they wish to speak a minority language, national governments should be under no obligation to provide education in an economically unproductive language, especially in times of budget constraints. It is generally accepted that national languages unite and help to create wealth while minority regional languages divide. Furthermore, governments have a duty to ensure that young people can fulfil their full potential, meaning that state education must provide them with the ability to speak and work in their national language and so equip them to participate responsibly in national affairs. People whose language competence does not extend beyond the use of a regional tongue have limited prospects. This means that while many people may feel a sentimental attachment to their local language, their government’s position should be one of benign neglect, allowing people to speak the language, but not acting to prevent its eventual disappearance.
Many PhD students studying minority languages lack the resources to develop their language skills, with the result that they have to rely on interpreters and translators to communicate with speakers of the language they are studying. This has a detrimental effect on the quality of their research. At the same time, they have to struggle against the frequently expressed opinion that minority languages serve no useful purpose and should be allowed to die a natural death. Such a view fails to take into account the fact that a unique body of knowledge and culture, built up over thousands of years, is contained in a language and that language extinction and species extinction are different facets of the same process. They are part of an impending global catastrophe which is beginning to look unavoidable.

The 23rd Southeast Asian Games (also known as the 2005 SEAG) were held in the Philippines from November 27th to December 5th in 2005. The games were participated by the eleven nations of Southeast Asia. This was the first time that the opening and closing ceremonies were held in a large open field, despite the fact that Manila has many stadiums and arenas. The organization decided to hold the games at an open space to accommodate the large number), of participants and spectators. As a result, the 2005 SEAG ranks as having largest audience having reached 200,000 people during the opening and, closing ceremonies. These games were also noted for having the most number delegates in the history of the SEA Games. In the end, all participating Countries received medals. The event was meant to tighten ties among Southeast Asian countries as a region and as a preparation as well for the upcoming Asian Games and Olympic Games.
The first gold medal of the games was awarded to Singapore on November 25th when their water polo team came out undefeated during the round-robin tournament round. The Philippine team took the silver medal in that event, and Malaysia brought home the bronze. 
East Timor received its first ever medal as a sovereign nation in the Philippines indigenous sport of Arnis.
The Games were also considered a valuable opportunity for athletes to gain competition experience and preparation for upcoming Asian Games and Olympic Games. It was purposely created strengthen friendship, solidarity and understanding among neighboring countries in the region. 
This was the third SEA Games to hosted by the Philippines. The last two times the Philippines hosted the games were in 1981, and again in 1991. Although the majority of events took place in Manila, logistical hurdles required the unusual step of spreading-out the events across the country; to ten other cities. This arrangement, was not seen favorably by the participating countries who anticipated travel and accommodation issues to arise; a worry which was confirmed soon their arrival.

Coral reefs are some of the most diverse ecosystems in the world, housing tens of thousands of marine species. With their hardened surfaces, corals are sometimes mistaken as being rocks. And, because they are attached, “taking root” to the seafloor, they are often mistaken for plants. However, unlike rocks, corals are alive. And unlike plants, corals do not make their own food. Corals are in fact animals. Appearing as solitary forms in the fossil record more than 400 million years ago, corals are extremely ancient animals that evolved into modern reef-building forms over the last 25 million years.
Coral reefs are the largest structures on earth of biological origin. Coral reefs are unique and complex systems. Rivaling old growth forests in longevity of their ecological communities, well-developed reefs reflect thousands of years of history.
Corals are ancient animals related to jellyfish and anemones. The branch or mound that we often call “a coral” is actually made up of thousands of tiny animals called polyps. A coral polyp is an invertebrate that can be no bigger than a pinhead to up to 30 centimeters (1 foot) in diameter. The polyps extend their tentacles at night to sting and ingest tiny organisms called plankton and other small creatures. Each polyp has a saclike body and a mouth that is encircled by stinging tentacles. The polyp uses calcium carbonate (limestone) from seawater to build a hard, cup-shaped skeleton. This skeleton protects the soft, delicate body of the polyp.
Reefs only occur in shallow areas that are reachable by sunlight because of the relationship between coral and algae. Various types of microscopic algae, known as Symbiodinium, live inside of the coral, providing them with food and helping them to grow faster.
There are over 2,500 kinds (species) of corals. About 1,000 are the hard corals that build coral reefs. Other corals are soft corals. Soft corals have skeletons that are flexible and can bend with the water. The three main types of coral reefs are fringing reefs, barrier reefs, and coral atolls. The most common type of reef is the fringing reef. This type of reef grows seaward directly from the shore. They form borders along the shoreline and surrounding islands. When a fringing reef continues to grow upward from a volcanic island that has sunk entirely below sea level, an atoll is formed. Atolls are usually circular or oval in shape, with an open lagoon in the center. Any reef that is called a barrier reef gets its name because its presence protects the shallow waters along the shore from the open sea. That protection promotes the survival of many types of sea plant and animal life.

It can be inferred from the passage that coral reefs ______________.

Almost as soon as World War II ended, the debate began over who had actually done the  most on the Allied side to ensure the defeat of the Axis powers. The Russians only needed to point to their twenty million plus war dead to justify their rights in Eastern Europe and their new  position as a great power on the world stage. Yet, Americans could also claim that they had done as much, if not more, as the Russians to defeat the Axis enemy. In hindsight, it is obvious that  despite its greater number of dead, the Russian effort ranks second place to the American. In  particular, the American effort seems greater in light of three crucial points: it was fighting at  extreme distances from its home territory; it simultaneously fought three different enemies on a multitude of complex fronts with air, naval, land forces; and finally, it supplied many other fighting  forces, including the Russians, with massive amounts ofmaterial. 

The main fronts of World War II were in North Africa, Italy, Western and Eastern Europe, the Pacific Ocean, China, and India. The United States military forces fought on or supported  every front, all of which were at extreme distances from the continental United States. A great logistical effort required to support both its own forces and those of many other nations. Above all,  supply ships were essential because without the supply ships, all would have been in vain.  Keeping the world's sea lanes free was one of the great accomplishments of the United States  Navy and her allies, especially the British and Canadians. This allowed ships to traverse great  distances and bring American and other Allied fighting forces to face the Axis powers. The Russians, on the other hand, were  fighting in their own country for much of the war and were close to their supply lines. They fought on one continuous font and did not have to travel far to meet the enemy. 

The United States fought all three great Axis powers during the war: Germany, Japan, and  Italy. While it cannot be denied that the Russian did the lion's share of the fighting against  Germany and the lesser Axis powers of Finland, Hungary, Romania, and Bulgaria for a longer  time, it was not until the last days of the war that Russia attacked Japan. As for the Italians, the  Russians only met the reluctant few whom Hitler managed to coerce for his Russian campaign. Another area to take into consideration is the strategic bombing campaign that the Americans and  British waged against German industry, something that the Russians did not take part in at all.  Finally, with the exception of the Baltic Sea, the Russian navy played a very minor role in the war  compared to American's navy. Despite significant aid from the British, Australians, and New Zealanders, the Americans bore the brute of the Pacific fighting. 

The Chinese tied down a massive number of Japanese troops on the Asian mainland, but  they were supplied almost exclusively by the United States. American arms, support equipment,  food, and clothing went to the four corners of the world during the war even before American officially entered it in 1941. Indeed, the Russian Red Army rode into Eastern Europe on the wheels  of over 300,000 American trucks, fed itself on a diet of American canned ham, and wore 

American boots. Coupled with all this were billion-dollar loans with generous terms of interest, which America gave to its allies. American was the only Allied nation that did not need to borrow  any money during the war.

   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; (1) cast, a lump formed by squeezing a sample in a clenched fist; (2) thread, a pencil shape formed by rolling soil between the palms; and (3) 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 ______.

      To quote CREST founder Dr. Martha Honey, we earnestly believe that ecotourism is “simply a better way to travel.” Here’s a look at how this transformational approach to travel benefits conservation, increases cross-cultural understanding, and ultimately turns travelers into environmental advocates:
       To see how ecotourism benefits nature and wildlife, let’s look at endangered species such as African Elephants. Ivory from Elephant tusks is worth $1500 a pound on the black market, which has led to a dramatic increase in poaching. But Elephants are worth 76 times more alive than dead. When you consider the revenue from wildlife photography tours, luxury safari camps, and other ecotourism offerings, a single Elephant is worth $1.3 million over the course of its lifetime! Ecotourism offers a long-term alternative to exploitation, generating sustainable revenue and ensuring better overall health of the ecosystem.
       Nature reserves and national parks help prevent deforestation and pollution, while also protecting the habitat of endemic species. The revenue that ecotourism provides can help replace profits from exploitative practices such as mining or slash ‘n’ burn agriculture. It can also help ensure the long-term financial viability of the area. Naturalist guides also help travelers understand the value of a pristine ecosystem, and teach them about the importance of conservation. This ultimately help to create a more mindful and conscious legion of travelers.
      When managed properly, ecotourism can offer locals alternative revenue streams. In wildlife-rich countries such as Rwanda, former poachers are often employed as guides or trackers, capitalizing on their knowledge of the animals and their habitat. In Costa Rica, unemployment has fallen to less than 10% since the country started building its ecotourism infrastructure in the 1970s. Involving local communities in tourism management empowers them by ensuring that more revenue is reinvested locally. Ecotourism also offers indigenous peoples an opportunity to remain on ancestral land, conserve it, and preserve traditional culture.
      Sure, being a responsible traveler takes a greater level of commitment to being conscious and mindful of the impact we have on the destinations we visit. But ecotourism also offers us incredible, transformative experiences, allowing us to develop closer personal relationships to the nature, wildlife, and local people we encounter during our adventures. Learning about ecotourism can permanently change your understanding of mankind’s role in our planetary ecosystem. And once you’ve had that sort of travel experience, you’ll never want to travel the traditional way again.

American music, in most of its various forms, can be traced back to the music of the  earliest African- Americans. Even though these Americans came here under the worst of  circumstances, they still brought with them traditions, and developed new traditions of their own, that have grown into what is recognized around the world today as American music. 

Musicians, like other artists, are usually quick to give credit where credit is due. Just as a  writer quotes his sources, a musician credits those musicians who inspired him. In the case of the  early African-Americans, that is not always easy. Many of the slaves who brought musical  traditions from Africa will never be known by name. No one wrote their history. Many of the slaves who sang work songs in the fields will never be known by name. No one wrote their history either. 

However, there is a lot that we do know. 

The first well-recognized form of African-American music was spirituals. Spirituals are religious songs. They are songs that tell a story or express emotions. Spirituals have a strong  rhythm. They are often sung by a group, sometimes with a leader who sings a line or two alone and a chorus that sings the refrain. Spirituals originated in the Southern United States. Spirituals sung by slaves often expressed the hope for freedom that was so important in their lives. Well know spirituals include "Go Down Moses," "Deep River," and "Swing Low SweetChariot." After slavery ended, spirituals began to spread to other parts of the United States. Harry  Thacker Burleigh was one of the first singers to perform spirituals on stage in a concert. Marian Anderson, well known for her classical singing, helped spirituals to gain a wider audience too.  Spirituals influenced the development of another well-known form of American music - the blues. The blues were a more individual style of music than spirituals. Blues were often sung  solo, and sometimes they were accompanied by guitar music. As the name suggests, the blues were often about sadness and facing troubles. However, the blues could also be funny, positive, and  even defiant. One blues singer, loved for her strong, beautiful voice, was Bessie Smith. Another  early blues musician was W. C. Handy. Handy was not only a musician, he also wrote music,  promoted concerts, and published bluessongs. 

During the time that the blues were spreading across the country, another style of music  was also quickly gaining in popularity. Ragtime was energetic music with a complicated,  syncopated beat. Often played on the piano, ragtime was the latest and most sophisticated in American popular music. The best-known  ragtime musician was probably Scott Joplin, who wrote many hit ragtime pieces for the piano  including "Maple Leaf Rag." 

Eventually, elements from all of these forms of music and more came back together. In  their own kind of melting pot, African rhythms, slave work songs, spirituals, blues, ragtime, and  other influences recombined to form the beginnings of that truly American art form - jazz. In the late 1800’s jazz was just beginning, but not long after the turn of the century, it would be the most popular American music. It would go on from there to worldwide popularity. Jazz would branch  out into many forms, and it would influence future styles of Americanmusic. 

Many musicians today credit earlier musicians such as Scott Joplin or Bessie Smith with inspiring their music. It’s a shame that they can’t also name the earliest African-Americans who  really began the traditions that led to the American music of today.

Which type of music is often involved with piano accompaniment? 

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.

   A rather surprising geographical feature of Antarctica is that a huge freshwater lake, one of the world’s largest and deepest, lies hidden there under four kilometers of ice. Now known as Lake Vostok, this huge body of water is located under the ice block that comprises Antarctica. The lake is able to exist in its unfrozen state beneath this block of ice because its waters are warmed by geothermal heat from the earth’s core. The thick glacier above Lake Vostok actually insulates it from the frigid temperatures on the surface.

   The lake was first discovered in the 1970s while a research team was conducting an aerial survey of the area. Radio waves from the survey equipment penetrated the ice and revealed a body of water of indeterminate size. It was not until much more recently that data collected by satellite made scientists aware of the tremendous size of the lake; the satellite-borne radar detected an extremely flat region where the ice remains level because it is floating on the water of the lake.

   The discovery of such a huge freshwater lake trapped under Antarctica is of interest to the scientific community because of the potential that the lake contains ancient microbes that have survived for thousands of years, unaffected by factors such as nuclear fallout and elevated ultraviolet light that have affected organisms in more exposed areas. The downside of the discovery, however, lies in the difficulty of conducting research on the lake in such a harsh climate and in the problems associated with obtaining uncontaminated samples from the lake without actually exposing the lake to contamination. Scientists are looking for possible ways to accomplish this.

Lake Vostok is potentially important to scientists because it________.

Today we take electricity for granted and perhaps we do not realize just how useful this discovery has been. Steam was the first invention that replaced wind power. It was used to drive engines and was passed through pipes and radiators to warm rooms. Petrol mixed with air was the next invention that provided power. Exploded in a cylinder, it drove a motor engine, Beyond these simple and direct uses, those forms have not much adaptability.
On the other hand, we make use of electricity in thousands of ways. From the powerful voltages that drive our electric trains to the tiny current needed to work a simple calculator,   and from the huge electric magnet in steel works that can lift 10 tons to the tiny electric magnet in a doorbell, all are powered by electricity. An electric current can be made with equal ease to heat a huge mass of molten metal in a furnace, or to boil a jug for a  cup of coffee. Other than atomic energy, which has not as yet been harnessed to the full, electricity is the greatest power in the world. It is flexible, and so adaptable for any task for which it is wanted. It travels so easily and with incredible speed along wires or conductors that it can be supplied instantly over vast distances.
To generate electricity, huge turbines or generators must be turned. In  Australia they use coal or water to drive this machinery. When dams are built, falling water is used to drive the turbines without polluting the atmosphere with smoke from coal. Atomic power is used in several countries but there is always the fear of an accident. A tragedy once occurred at Chernobyl, in Ukraine, at an atomic power plant used to make electricity. The reactor leaked, which caused many deaths through radiation.
Now scientists are examining new ways of creating electricity without harmful effects to the environment. They may harness the tides as they flow in and out of bays. Most importantly, they hope to trap sunlight more efficiently. We do use solar heaters for swimming pools but as yet improvement in the capacity of the solar cells to create more current is necessary. When this happens, electric cars will be viable and the world will rid itself of the toxic gases given off by trucks and cars that burn fossil fuels.

What do we call machines that make electricity?

 History of SEA Games

The Southeast Asian Games owes its origins to the Southeast Asian Peninsular Games or SEAP Games. On 22 May, 1958, delegates from the countries in Southeast Asian Peninsula attending the 3rd Asian Games in Tokyo, Japan had a meeting and agreed to establish a sport organization. The SEAP Games was conceptualized by Laung Sukhumnaipradit, then Vice-President of the Thailand Olympic Committee. The proposed rationale was that a regional sports event will help promote cooperation, understanding and relations among countries in the Southeast Asian Peninsula region. Thailand, Burma (now Myanmar), Malaya (now Malaysia), Laos, South Vietnam (now Vietnam) and Cambodia were the founding members. These countries agreed to hold the Games biannually. The SEAP Games Federation Committee was formed.

The first SEAP Games were held in Bangkok from 12-17 December, 1959 comprising more than 527 athletes and officials from Thailand, Burma, Malaysia, Cambodia, South Vietnam and Laos participating in 12 sports. At the 8th SEAP Games in 1975, the SEAP Federation considered the inclusion of Indonesia and the Philippines. The two countries were formally admitted in 1977, the same year when SEAP Federation changed their name to Southeast Asian Games Federation (SEAGF), and the games were known as the Southeast Asian Games. Brunei was admitted at the 9th SEA Games in Kualalumper, Malaysia, and East Timor at the 22nd SEA Games in Hanoi, Vietnam. The 23rd SEA Games held in the Philippines, which started from 27 November and ended on 5 December 2005, hosting the biennial event for the third time.

Indonesia officially took part in SEAP Games in 1975.

From the powerful voltages that drive our electric trains to the tiny current needed to work a simple calculator,   and from the huge electric magnet in steel works that can lift 10 tons to the tiny electric magnet in a doorbell, all are powered by electricity. An electric current can be made with equal ease to heat a huge mass of molten metal in a furnace, or to boil a jug for a  cup of coffee. Other than atomic energy, which has not as yet been harnessed to the full, electricity is the greatest power in the world. It is flexible, and so adaptable for any task for which it is wanted. It travels so easily and with incredible speed along wires or conductors that it can be supplied instantly over vast distances.
To generate electricity, huge turbines or generators must be turned. In  Australia they use coal or water to drive this machinery. When dams are built, falling water is used to drive the turbines without polluting the atmosphere with smoke from coal. Atomic power is used in several countries but there is always the fear of an accident. A tragedy once occurred at Chernobyl, in Ukraine, at an atomic power plant used to make electricity. The reactor leaked, which caused many deaths through radiation.
Now scientists are examining new ways of creating electricity without harmful effects to the environment. They may harness the tides as they flow in and out of bays. Most importantly, they hope to trap sunlight more efficiently. We do use solar heaters for swimming pools but as yet improvement in the capacity of the solar cells to create more current is necessary. When this happens, electric cars will be viable and the world will rid itself of the toxic gases given off by trucks and cars that burn fossil fuels.

 The advantage of harnessing the power of the tides and of sunlight to generate electricity is that they  ,................

An idea came to me, and I turned off the lights in the studio. In the dark ness, I put the  cello's spike into a loose spot on the carpet, tightened the bow and drew it across the open strings.  I took off my shirt and tried it again; it was the first time in my life I'd felt the instrument against  my bare chest. I could fell the vibration of the strings travel through the body of the instrument to  my own body. I'd never thought about that; music scholars always talk about the resonating properties of various instruments, but surely the performer's own body must have some effect on the sound. As I dug into the notes I imagined that my own chest and lung were extensions of the sound box; I seemed to be able to alter the sound by the way I sat, and by varying the muscular tension in my upper body. 
After improvising for a while, I started playing the D minor Bach suite, still in the  darkness. Strangely freed of the task of finding the right phrasing, the right intonation, the right bowing, I heard the music through my skin. For the first time I didn't think about how it would sound to anyone else, and slowly, joyfully, gratefully, I started to hear again. The note sang out,  first like a trickle, then like a fountain of cool water bubbling up from a hole in the middle of the desert. After an hour or so I looked up, and in the darkness saw the outline of the cat sitting on the floor in front of me, cleaning her paws and purring loudly. I had an audience again, humble as it was. 
So that's what I do now with the cello. At least once a day I find time to tune it, close my eyes, and listen. It’s probably not going to lead to the kind of come back I'd fantasized about for so long – years of playing badly have left scars on my technique, and, practically speaking, classical  musicians returning from obscurity are almost impossible to promote – but might eventually try giving a recital if I feel up to it. Or better yet, I may pay for Dr. Polk if our date at the concert goes well. Occasionally I fell a stab of longing, and I wish I could give just one more concert on the  great stage before my lights blink off, but that longing passes more quickly now. I take solace on the fact that, unlike the way I felt before, I can enjoy playing for myself now. I fell relaxed and expansive when I play, as if I could stretch out my arms and reach from one end of the apartment to the other. A feeling of the completeness and dignity surrounds me and lifts me up.

All of following are mentioned in paragraph 2 as part of the cellist's new way of  playing EXCEPT ...................

American music, in most of its various forms, can be traced back to the music of the  earliest African- Americans. Even though these Americans came here under the worst of  circumstances, they still brought with them traditions, and developed new traditions of their own, that have grown into what is recognized around the world today as American music. 

Musicians, like other artists, are usually quick to give credit where credit is due. Just as a  writer quotes his sources, a musician credits those musicians who inspired him. In the case of the  early African-Americans, that is not always easy. Many of the slaves who brought musical  traditions from Africa will never be known by name. No one wrote their history. Many of the slaves who sang work songs in the fields will never be known by name. No one wrote their history either. 

However, there is a lot that we do know. 

The first well-recognized form of African-American music was spirituals. Spirituals are religious songs. They are songs that tell a story or express emotions. Spirituals have a strong  rhythm. They are often sung by a group, sometimes with a leader who sings a line or two alone and a chorus that sings the refrain. Spirituals originated in the Southern United States. Spirituals sung by slaves often expressed the hope for freedom that was so important in their lives. Well know spirituals include "Go Down Moses," "Deep River," and "Swing Low SweetChariot." After slavery ended, spirituals began to spread to other parts of the United States. Harry  Thacker Burleigh was one of the first singers to perform spirituals on stage in a concert. Marian Anderson, well known for her classical singing, helped spirituals to gain a wider audience too.  Spirituals influenced the development of another well-known form of American music - the blues. The blues were a more individual style of music than spirituals. Blues were often sung  solo, and sometimes they were accompanied by guitar music. As the name suggests, the blues were often about sadness and facing troubles. However, the blues could also be funny, positive, and  even defiant. One blues singer, loved for her strong, beautiful voice, was Bessie Smith. Another  early blues musician was W. C. Handy. Handy was not only a musician, he also wrote music,  promoted concerts, and published bluessongs. 

During the time that the blues were spreading across the country, another style of music  was also quickly gaining in popularity. Ragtime was energetic music with a complicated,  syncopated beat. Often played on the piano, ragtime was the latest and most sophisticated in American popular music. The best-known  ragtime musician was probably Scott Joplin, who wrote many hit ragtime pieces for the piano  including "Maple Leaf Rag." 

Eventually, elements from all of these forms of music and more came back together. In  their own kind of melting pot, African rhythms, slave work songs, spirituals, blues, ragtime, and  other influences recombined to form the beginnings of that truly American art form - jazz. In the late 1800’s jazz was just beginning, but not long after the turn of the century, it would be the most popular American music. It would go on from there to worldwide popularity. Jazz would branch  out into many forms, and it would influence future styles of Americanmusic. 

Many musicians today credit earlier musicians such as Scott Joplin or Bessie Smith with inspiring their music. It’s a shame that they can’t also name the earliest African-Americans who  really began the traditions that led to the American music of today.

Today we take electricity for granted and perhaps we do not realize just how useful this discovery has been. Steam was the first invention that replaced wind power. It was used to drive engines and was passed through pipes and radiators to warm rooms. Petrol mixed with air was the next invention that provided power. Exploded in a cylinder, it drove a motor engine, Beyond these simple and direct uses, those forms have not much adaptability.
On the other hand, we make use of electricity in thousands of ways.
