   In developing countries, where three fourths of the world's population live, sixty percent of the people who can’t read and write are women. Being illiterate doesn’t mean they are not intelligent. It does mean it is difficult for them to change their lives. They produce more than half of the food. In Africa eighty percent of all agricultural work is done by women. There are many programs to help poor countries develop their agriculture. However, for years, these programs provided money and training for men.

   In parts of Africa, this is a typical day for a village woman. At 4:45 a.m, she gets up, washes and eats. It takes her a half hour to walk to the fields, and she works there until 3:00 p.m. She collects firewood and gets home at 4:00. She spends the next hour and a half preparing food to cook. Then she collects water for another hour. From 6:30 to 8:30 she cooks. After dinner, she spends an hour washing the dishes and her children. She goes to bed at 9:30 p.m.

   International organizations and programs run by developed nations are starting to help women, as well as men, improve their agricultural production. Governments have already passed some laws affecting women because of the UN Decade for Women. The UN report will affect the changes now happening in the family and society.

What does the word "run" in the last paragraph mean?

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 ______________.

The best explainer videos are realized by great background score. When was the last time you watched a silent movie? Never? Not for a while? A long while? Even if you remember watching one, it would still have had a background score, or you’ve accidentally pressed the mute button!
The importance of background music and sound effects for your explainer video, therefore, cannot be overstated. You may not need a full blown orchestra or classy jazz tones to create the mood, but whether going for a subtle effect, a professional demonstration or simply trying to attract customers, music is a must. Explainer videos have the emotional quotient working for them and music is just going to add more to make the viewers relate to the pain points you are highlighting in your video. Imagine if your favorite video game has no background music or sound effects to back the amazing graphics? Would you play it with the same feel and excitement? Nah! Same is the case with your explainer videos. They need to and should have apt sound effects to make them worth your viewer’s time.
While the focus of explainer videos production is more on passing the desired information and explaining technical and complex procedures easily, it doesn’t mean you’ll be distracting your viewers with the background music. The sound effects and music is not going to take the message away from your explainer, it’s just going to enhance it and turn it more watchable and share-able. Even if your video doesn’t require a background score, it must include some sound effects or else it would be not so good an experience for those who choose to watch it

The word “it” in paragraph 3 refers to _______.

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 has the closest in meaning to the phrase “give credit where credit is due”?

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. 
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 word “constraints” in the second language is closest in meaning to ___________.

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.

   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.

What is true of Lake Vostok?

Psychologists have debated a long time about whether a child's upbringing can give it the ability to do outstandingly well. Some think that it is impossible to develop genius and say that it is simply something a person is born with. Others, however, argue that the potential for great achievement can be developed. The truth lies somewhere between these two extremes.
It seems very obvious that being born with the right qualities from gifted parents will increase a child's ability to do well. However, this ability will be fully realized only with the right upbringing and opportunities. As one psychologist says, "To have a fast car, you need both a good engine and fuel.” Scientists have recently assessed intelligence, achievement, and ability in 50 sets of identical twins that were separated shortly after birth and brought up by different pa rents. They found that achievement was based on intelligence, and later influenced by the child's environment
One case involving very intelligent twins was quoted. One of the twins received a normal upbringing, and performed well. The other twin, however, was brought up by extremely supportive parents and given every possible opportunity to develop its abilities. That twin, though starting out with the same degree of intelligence as the other, performed even better.
This case reflects the general principle of intelligence and ability. The more favorable the environment, the more a child's intelligence and ability are developed. However, there is no link between intelligence and the socioeconomic level of a child's family.  In other words, it does not matter how poor or how rich a family is, as this does not affect intelligence.
Gifted people cannot be created by supportive parents, but they can be developed by them.
One professor of music said that outstanding musicians usually started two or three years earlier than ordinary performers, often because their parents had recognized their ability. These musicians then needed at least ten years' hard work and training in order to reach the level they were capable of attaining.
People who want to have very gifted children are given the following advice:
- Marry an intelligent person.
- Permit children to chase their own interests rather than the interests of the parents.
- Start a child's education early but avoid pushing the child too hard.
- Encourage children to play; for example, playing with musical instruments is essential for a child who wants to become an outstanding musician.

When encouraging their gifted children, parents should avoid .....................

Games and sports are an important and essential part of a person's life. Along with the study, games, and sports are also important. Hence, most schools conducts various games competitions and sports. Along with the mental development of every person, physical development is also which needs to be taken into consideration. Sports is an important part of a student’s life as well. So, what is the importance of sports and games?

Sports gives us a good exercise which makes us physically strong and increases our stamina and strength. Regular sports activities make us active and lead to good health. Playing Games makes us aware of our environment i.e. Makes us mentally awake and increases our concentration power. Various Games needs good strategies for better performance and teamwork, so it increases our thinking ability and teaches us the power of teamwork and to find a way out of difficult situations. Games and sports also need a lot of energy. It makes us energetic. Games and Sports needs a lot of cooperation between the players. Hence it increases cooperation with each other.

And at last, all of the games have their own rules and regulations which if not followed, leads to negative points. Hence, we can say that it teaches us the importance of following rules in life.

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.

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.

According to paragraph 5, why did the author claim that people will prefer ecotourism over normal one?

Large animals that inhabit the desert have evolved a number of adaptations for reducing the effects of extreme heat. One adaptation is to be light in color,  and to reflect rather than absorb the Sun's rays. Desert mammals also depart from the normal mammalian practice of maintaining a constant body temperature. Instead of trying to keep down the body temperature deep inside the body, which would involve the expenditure of water and energy,  desert mammals allow their temperatures to rise to what would normally be fever height, and temperatures as high as 46 degrees Celsius have been measured in Grant's gazelles. The overheated body then cools down during the cold desert night, and indeed the temperature may fall unusually low by dawn,  as low as 34 degrees Celsius in the camel. This is an advantage since the heat of the first few hours of daylight is absorbed in warming up the body, and an excessive buildup of heat does not begin until well into the day.

Another strategy of large desert animals is to tolerate the loss of body water to a point that would be fatal for non-adapted animals. The camel can lose up to 30 percent of its body weight as water without harm to itself, whereas human beings die after losing only 12 to 13 percent of their body weight. An equally important adaptation is the ability to replenish this water loss at one drink. Desert animals can drink prodigious volumes in a short time, and camels have been known to imbibe over 100 liters in a few minutes. A very dehydrated person, on the other hand, cannot drink enough water to rehydrate at one session, because the human stomach is not sufficiently big and because a too rapid dilution of the body fluids causes death from water intoxication. The tolerance of water loss is of obvious advantage in the desert, as animals do not have to remain near a water hole but can obtain food from grazing sparse and far-flung pastures. Desert-adapted mammals have the further ability to feed normally when extremely dehydrated, it is a common experience in people that appetite is lost even under conditions of moderate thirst.

Which of the following is NOT mentioned as an adaptation of large desert animals?

 Choose the item among A, B, C or D that best answers the question about the passage:

"The 22nd SEA Games were launched by an impressive opening ceremony at Hanoi’s My Dinh National Stadium on December 5th 2003, in front of over 40,000 awed spectators. On behalf of the host country, Prime Minister Phan Van Khai declared the 22nd SEA Games open.
 Deputy Prime Minister Pham Gia Khiem, Chairman of the National Steering Board for the 22nd SEA Games, Minister-Chairman Nguyen Danh Thai, and Hanoi Mayor Hoang Van Nghien presented flowers and banners to the 11 participating sports delegations.
 On behalf of the referees and athletes, referee Hoang Quoc Vinh and shooter Nguyen Manh Tuong swore to an oath of “Solidarity, Honesty and Fair Play”.After the “ritual” part of the ceremony, a laser light show kicked off the “festival” segment. More than one thousand artists, dressed in green and sea blue representing the forest and the sea, then presented the first chapter of the performance, named “The Land of the Dragon and Fairy”.
 The scene depicted the legend of Vietnam’s origins, featuring the father-Dragon and mother-Fairy, and ended with young men and women lining up in an S-shaped pattern, a Symbol of Vietnam as a country.
 The second part of the programme, named “Cooperation for Peace” featured children holding five pointed-stars and entering from the stadium's four gates, representing Hanoi, the Capital City with one thousand years of history.
 Dancing men and women in traditional costumes of ASEAN members and East Timor concluded the third segment, named “United ASEAN Looks To The Future”, which comprised four performances: “Lands by the Pacific Ocean,” “Essential Convergence,” “New Tune,” and “ASEAN Towards The Future.”
 The Games mascot, the Golden Buffalo, and 22 singers (standing for the 22nd Games) then took centre stage, singing the Games official song “For a World of Tomorrow”. The whole show ended as thousands of flying balls were released and fireworks were fired from four places in Hanoi."
