The primary attraction of snorkeling is the opportunity to observe underwater life in a natural setting, such as coral reefs, fish, starfish, and mollusks. Other organisms that can be seen while snorkeling include various forms of seaweed, jellyfish, shrimp and sea turtles. Snorkeling requires no special training, only the ability to swim and to breathe through the snorkel. However, it is considered advisable that one get some instruction from a tour guide, dive shop, or equipment rental shop, any of which often can be found around popular snorkeling locations. Instruction generally covers equipment usage, basic safety, what to look for, and what to look out for, including how not to damage fragile organisms such as coral. As with scuba diving, it is always recommended that one, should not snorkel alone, but rather with a friend, a guide, or a tour group

Swim fins used in snorkeling are usually longer than those used in diving. Snorkel is a tube about thirty centimeters (twelve inches) long, usually J-shaped, fitted with a mouthpiece, and constructed of rubber or plastic. It is used for breathing air from above the water surface when the mouth and nose are submerged, either when snorkeling or during a surface swim before or after scuba diving. The snorkel usually has a piece of rubber that attaches the snorkel to the outside of the strap of the diving mask, as sticking the snorkel in between the strap and the mask could cause the mask to leak, or risk losing the snorkel should the diver choose to switch to scuba.

Typically, the diving mask also serves to prevent breathing through the nose, so that one is forced to breathe through the snorkel. This also provides some negative pressure which helps keep the .mask sealed against the face, though attempting to breathe out through the nose can break this seal and fog the mask.

The snorkeler breathes through his ________.

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.

According to the passage, why is it easy to forget the people who first brought  musical tradition to America?

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.

   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.

The word "fine" in the passage is closest in meaning to ______.

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.

      New research shows that long-term changes in diseases in ocean species coincides with decades of widespread environmental change. The paper, "Increases and decreases in marine disease reports in an era of global change," was published Oct. 9 in Proceedings of the Royal Society B.

      Understanding oceanic trends is important for evaluating today's threats to marine systems, and disease is an important sentinel of change, according to senior author Drew Harvell, professor of marine biology at Cornell University. "Disease increases and decreases can both be bad news," said lead author Allison Tracy, who studied with Harvell. "The long-term changes in disease that we see here may result from anthropogenic pressure on plants and animals in the ocean." The researchers examined marine infectious disease reports from 1970 to 2013, which transcend short-term fluctuations and regional variation. They examined records of corals, urchins, mammals, decapods, fish, mollusks, sharks, rays, seagrass and turtles.

       For corals and urchins, reports of infectious disease increased over the 44-year period. In the Caribbean, increasing coral disease reports correlated with warming events. It is widely known that coral bleaching increases with warming, but Harvell said they have established a long-term connection between warming and coral disease. "We've finally linked a coral killer like infectious disease to repeated warming bouts over four decades of change," she said. "Our study shows that infectious disease reports are associated with warm temperature anomalies in corals on a multi-decadal scale." These results improve understanding of how changing environments alter species interactions, and they provide a solid baseline for health of marine life in the period studied.

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 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 Nguyên 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."

They seem to feel that the danger of the traffic is (24) ___________ to the risk of having their conversation be overheard. This has led to a behavior that Laser has called "clustering." At a busy time of day on the streets of London, you may find small crowds of cell phone users grouped together, each one talking into a cell phone. Even when it is raining—as it is often in London—people still prefer not to hold their conversations where others could hear. They talk (25) _____________ their umbrellas or in a doorway.

Down did an apple fall when he was passing under the tree.

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.
