DIRECTIONS: Chооse the cоrrect аnswer for eаch question.An Incredible Journey[A] The Polos - Mаrco, his father, Niccolo, and his uncle, Maffeo - had been traveling for three and a half years when they finally achieved their objective - a long-awaited meeting with the powerful Mongol leader Kublai Khan. The historic event took place in 1275 at the Khan's luxurious summer capital in Shangdu, in what is now northern China. Kublai Khan was surprisingly informal as he greeted his tired guests: "Welcome, gentlemen! Please stand up. How've you been? How was the trip?" [B] Marco Polo's trip had, in fact, started more than 9,000 kilometers away in Venice when he was just a teenager. His father and uncle already knew Kublai Khan from a previous visit nine years earlier, when they had spent a short time in Shangdu. On this second trip, the Polos stayed for 17 years before they returned home. They made themselves useful to the Khan, and undertook various missions and tasks for him. It is likely that the Khan considered it an honor that these Europeans - who were rare in China - had made this extremely difficult journey, and he took the opportunity to make good use of their skills and knowledge. [C] While he was in the service of Kublai Khan, "the most powerful man in people and in lands and in treasure that ever was in the world," Marco Polo was able to learn and experience many things that were new to Europeans. In his travel journal, he wrote that Kublai Khan's palace was the greatest he had ever seen. He admired the Khan's recently completed new capital - Daidu - whose streets were "so straight and so broad." The city was located in what is now the center of Beijing, and Kublai Khan's city planning can still be perceived in the straight, broad streets of China's modern capital.[D] We learn from Marco Polo that, in the administration of his empire, Kublai Khan made use of a fast and simple message system. Horse riders spaced every 40 kilometers allowed messages to cover 500 kilometers a day. As soon as one horse had run 40 kilometers, the next horse would run the next 40 kilometers, and so on. Marco also learned the secret of asbestos cloth, which is made from a mineral and doesn't catch fire. Paper money also took him by surprise, since it was not yet used in the West at that time. Homes were heated with "black stones ... which burn like logs." Those stones were coal - unknown in most of Europe - and were so plentiful that many people had a hot bath three times a week.[E] Although the Khan did not want his visitors to leave, the Polos finally received permission to return home in 1292. Marco continued his observations while on the ocean voyage by way of Sumatra and India. After he returned home, Marco completed a book about his trip, full of details about his amazing cultural experiences. It was probably the single greatest contribution to geographical knowledge ever made to the West about the East. In paragraph C, who does the most powerful man refer to?

Two words are extra.The Race to India[A] In the 15th century, there was a race among Europeans to reach India because of the riches it offered. Indian spices1 were like gold. Because of the high demand, European traders could make a fortune2 by selling them. [B] The problem, however, was that these spices were not so easy to obtain. The journey to India was a complicated one. Traveling by horse was very slow, especially in mountainous areas. Furthermore, reaching India by land involved passing through countries that were not always friendly to Europeans. The chances of being attacked were high. [C] When the Ottoman Empire3 took over Constantinople4 in 1453, the journey to India became even more difficult. The Ottomans took control of the trade routes between Europe and Asia for their own financial benefits. This forced the Europeans to try to reach India by sea. It began what is now known as the Age of Discovery.Two Great Explorers [D] Most people know the story of Christopher Columbus. He was hired by the king of Spain to reach India by crossing the Atlantic Ocean. He did not succeed in this mission. The reason for this is because, on his way, he found America instead - a "new world" unknown to Europeans. For this achievement in the year 1492, Columbus is considered the most famous explorer of the Age of Discovery.[E] If Portuguese explorer Vasco da Gama were still alive, what might he say about Columbus's fame? He might simply shake his head. After all, Vasco da Gama was the first explorer to reach India by sea. [F] Unlike Columbus, Vasco da Gama attempted to reach India by sailing around the southernmost point of Africa and into the Indian Ocean. His trip was long and full of challenges. Although he and his crew sailed from Portugal in July 1497, they did not reach India until May 1498. Despite this, he reached his objective. Europeans had a new route to India and, more importantly, its spices. For this reason, although less famous than Columbus, Vasco da Gama has also been admired for his discoveries as one of the greatest explorers in world history. 1 Spices are powders or seeds from plants which are used in cooking to give flavor to food (e.g., black pepper or cinnamon) 2 Fortune is a large amount of money or great wealth.3 The Ottoman Empire was a large empire based in Turkey, founded in the 13th century, which included large parts of Eastern Europe, Asia, and North Africa. 4 Constantinople is present-day Istanbul, the largest city in Turkey.

DIRECTIONS: Chооse the best аnswer fоr eаch question. Sextuplets [A] Most of us hаve met a pair of twins or triplets once or twice in our lives. But how many people know a set of sextuplets: six children born at the same time to the same mother? Not very many of us have. This is why the Dilley family is so famous.[B] Keith and Becki Dilley got married in 1986 and wanted to have children right away. After five years of no children, doctors gave Becki a special medication to help her get pregnant. It worked! But Becki wasn't pregnant with just one baby. She was pregnant with five - or that's what the doctors thought at first. [C] On May 25, 1993, Becki went to the hospital to give birth. The doctor delivered five healthy babies before Becki felt a sixth set of feet. The last Dilley baby, the sixth one, was quite a surprise. The babies had to stay in the hospital for several months. Some of them needed special machines to help them breathe. Others were so small and fragile that Becki and Keith could not hold them. After three months, the babies were finally able to go home.[D] Life in the Dilley household was quite busy, as anyone can imagine. There were six diapers to change, six bottles to prepare, six tiny outfits to wash, and so on. Thankfully, the Dilleys had family nearby who could help carry the load. Grandparents, aunts, and uncles all pitched in to help.[E] The sextuplets are grown up now. They have families of their own and work at various jobs. They seem to be just like other young adult, but they always have an amazing story to tell.What does the word fragile mean in paragraph C?

Airbus sоld аn аircrаft, A400, tо Delta Air Lines, and billed $80 milliоn payable in six months. Airbus is concerned with the euro proceeds from international sales and would like to control exchange risk. The current spot exchange rate is $1.10/€ and six-month forward exchange rate is $1.09/€ at the moment. Airbus can buy a six-month put option on U.S. dollars with a strike price of €0.95/$ for a premium of €0.01 per U.S. dollar. Currently, six-month interest rate is 5.4% per annum in the euro zone and 6.0% per annum in the U.S. Compute the guaranteed euro proceeds from the American sale if Airbus decides to hedge using a forward contract. Answer in Euros to two decimal places and do not use a currency symbol.
