Aspirin's origins go back at least as early as 1758. In that year, Englishman Edward Stone noticed a distinctive bitter flvor in the bark of the willow tree. To Stone, this particular bark seem to have much in common with "Peruvian Bark", which had been used medicinally since the 1640s to bring down fevers and to treat malaria, stone decided to test the effectiveness of the willow bark. He obtained some, pulverized it into tiny pieces, and conducted experiments on its properties. His tests demonstrated that this pulverized willow bark was effective both in reducing high temperatures and in relieving aches and pains. In 1763, stone presented his tiding to the British Royal Society. Several decades later, further studies on the medicinal value of the willow bark were being conducted by two Italian scientists. These chemists, Brugnatelli and Fontana, determined that the active chemical that was responsible for the medicinal characteristics in the willow bark was the chemical salicin, which is the active ingredient of today's aspirin. The name "aspirin" is the trade name of the drug based on the chemical salicin, properly known as acetylsalicylic acid.The trade name "aspirin" was invented for the drug in the 1890s by the Bayer Drug Company in Germany. The fist bottles of aspirin actually went on sale to the publicjust prior to the turn of the century, in 1899.
7. What is true about Brugnatelli and Fontana?

Fish that live on the sea bottom benefit by being flat and hugging the contours. There are two very differcent types of flatfish and they have evolved in very separate ways. The skates ad rays, relatives of the rharks, have become flat in what might be called the obivious way. Their bodies have grown out sideways to form grat “wings”. They look as though they have been flattened but have remained symmetrical and “the right way up”. Conversely, fish such sas plaice, sole, and halibut have become flat in a different way. There are bony fish which have a marked tendency to be flattened in a vertical direction; they are much “taller” than they are wide. They use their whole, vertically flattened bodies as swimming surfaces, which undulat through the water as they move. Therefore, when their ancestors migrate to the seabed, they lay on one side than on their bellies. However, this raises the problem that one eye was always looking down into the sand and was effectively useless – In evolution this problem was soleved by the lower eye “moving” around the other side. We see this process off moving around enacted in the development of every young bony flatfish. It starts life swimming near the surface, and is symmetrical and vertically flattened, but then the skull starts to grow in a strange asymmetrical twisted fashion,, so that one eye, for instance the left, moves over the top of the head upwards, an old Picasso – like vision. Incidentally, some species of 20 flatfish settle on the right side, others on left, and others on either side.

The word “conversely” is closest in meaning to     .

Ocean Currents and the Turning of the Tide
If you take a seat at the beach and look out across the water, you’ll soon notice that oceans have a rhythm of their own. Throughout the course of the day, sea levels will rise and fall, and water will flow through routes and end up in different places. But how does it all work? One force at play is tides, which are the alternating water levels of the ocean. There are two major gravitational forces which cause tides: the sun and the moon. The moon’s force has a tugging effect on oceans which causes them to bulge outwards on opposite sides of the planet. Solar tides operate according to the same principles. However, they are only about 50 percent as strong due to the distance between the sun and the earth. As tides rise and fall, they create tidal currents. The strongest tidal currents occur at the height of both high and low tides. Unlike other currents, they do not flow in a continuous stream. Far from shore, tidal currents don’t have much of an effect. Yet when they pass through narrow area, like harbours and bays, tidal currents can displace plants, animals, and sediment. Although they may certainly shake things up, not all of the damage is negative. Tidal currents can spread fish eggs across long distances to assist fertilization, in addition to transporting key nutrients. Another category of currents is ocean currents. These currents occur near the top of the water, and are mainly powered by the wind. One example of these is coastal currents, which are those beachgoers encounter when going for a swim. One of the strongest and most well-known currents is the Gulf Stream, which brings warm water from the Gulf of Mexico all the way to Western Europe. Meanwhile, Deep Ocean currents are a powerful force in the depths of oceans. The strongest of these has been nicknamed the global conveyor belt, and it moves much slower than surface currents. Although we can’t see it in operation, it’s about 16 times as powerful as all the earth’s rivers put together. As the global conveyor belt pushes water around the planet, it carries nutrition and carbon dioxide to places that truly need them. In the end, although there are several currents working on oceans simultaneously, they each seem to perform a necessary function that creates balance for life in the sea.
2. The most powerful tidal currents occur __________

Frozen Fitness
A man stands over a bathtub that is filled with ice. Although it is the middle of winter, he slowly slides into the tub and submerges his body underneath the water. Within seconds, he begins to shiver, but after a few minutes he is able to settle down. Despite the temperature, he will remain in the tub for the next 30 minutes. He is taking advantage of cold thermogenesis, a growing trend that could improve people’s health. Thermogenesis is an internal process that mammals undergo to generate heat when they are subjected to cold temperatures. In modern society, humans rarely requires this ability because we have heated homes and offices during the winter season. Recent studies, however, indicate that by doing so we could be missing out on some wonderful health benefits. Being subjected to cold temperatures regularly has been shown to boost men’s testosterone levels. It also boosts metabolism, which allows people to burn fat more efficiently. Some people have reported that cold thermogenesis also provides a mental lift once you have overcome the initial shock of the cold water. The positive effects of thermogenesis were known before, but it only started to become popular after the 2008 Olympics. One man who helped spark this craze was Ray Cronise, a NASA scientist and entrepreneur. He was reading an article that reported Michael Phelps ate 12,000 calories per day while training. The calories were so high that led him to believe that something else besides exercise was helping Phelps to stay thin and muscular: the icy water in the swimming pool. So he conducted his own experiment by drinking several glasses of ice water and exposing himself to cold water. After six weeks of this regiment, he had lost 30 pounds. There are several routines that a person can adopt if they are interested in starting their own thermogenesis routine. One method is ice baths. This method may be a bit too drastic for average people though. Instead, people may want to begin by dunking their face in cold water for a few seconds, and then gradually increase the time. Next, they can progress to cold showers and baths before moving on ice baths. An even more convenient way is to place an ice packet on the back of your neck for 15 to 20 minutes every evening. Although these methods may be extreme, many are willing to give them a go to improve their health
4. All of the following are true about the benefits of thermogenesis EXCEPT that __________

Chess, often (1)______ to as the Royal Game, is the oldest of all board games which do not contain an element of chance. The origins of chess are uncertain, (2)______ there are a number of legends regarding its invention. One story says that it was King Solomon who invented chess, another that it was the Greek god Hermes, and yet another that the Chinese mandarin Han-Sing was responsible for its creation. In fact, chess almost certainly originated in India in the sixth or seventh century AD. The game’s popularity then spread quickly through Persia (now known as Iran) and from there came to Europe. The first documented reference to chess in literature is in a Persian romance which was written about 600 AD. It is (3)_______ the word ‘chess’ comes from ‘shah’, the Persian word for ‘king’ and that ‘checkmate’, the game’s winning (4)_______, comes from the phrase ‘shah mat’, (5)______ ‘the king is dead’.

In it, he introduced the concept of ‘castling’, which had not been part of the game until then.
