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:

Ranked as the number one beverage consumed worldwide, tea takes the lead over coffee in both popularity and production with more than 5 million metric tons of tea produced annually. Although much of this tea is consumed in Asian, European and African countries, the United States drinks its fair share. According to estimates by the Tea Council of the United States, tea is enjoyed by no less than half of the U.S. population on any given day. Black tea or green tea - iced, spiced, or instant - tea drinking has spurred a billion-dollar business with major tea producers in Africa and South America and throughout Asia.

Tea is made from the leaves of an evergreen plant, Camellia sinensis, which grows tall and lush in tropical regions. On tea plantation, the plant is kept trimmed to approximately four feet high and as new buds called flush appear, they are plucked off by hand. Even in today’s world of modern agricultural machinery, hand harvesting continues to be the preferred method. Ideally, only the top two leaves and a bud should be picked. This new growth produces the highest quality tea.

After being harvested, tea leaves are laid out on long drying racks, called withering racks, for 18 to 20 hours. During this process, the tea softens and becomes limp. Next, depending on the type of tea being produced, the leaves may be crushed or chopped to release flavor, and then fermented under controlled conditions of heat and humidity. For green tea, the whole leaves are often steamed to retain their green color, and the fermentation process is skipped. Producing black teas requires fermentation during which the tea leaves begin to darken. After fermentation, black tea is dried in vats to produce its rich brown or black color.

No one knows when or how tea became popular, but legend has it that tea as a beverage, was discovered in 2737 B.C. by Emperor Shen Nung of China when leaves from a Camellia dropped into his drinking water as it was boiling over a fire. As the story goes, Emperor Shen Nung drank the resulting liquid and proclaimed the drink to be most nourishing and refreshing. Though this account cannot be documented, it is thought that tea drinking probably originated in China and spread to other parts of Asia, then to Europe, and ultimately to America colonies around 1650.

With about half the caffeine content as coffee, tea is often chosen by those who want to reduce, but not necessarily eliminate their caffeine intake. Some people find that tea is less acidic than coffee and therefore easier on the stomach. Others have become interested in tea drinking since the National Cancer Institute published its findings on the antioxidant properties of tea. But whether tea is enjoyed for its perceived health benefits, its flavor, or as a social drink, teacups continue to be filled daily with the world’s most popular beverage.

Question 38: Which of the following is NOT true about the tea production process?

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:

Sony Pictures released a remarkable and intriguing film entitled The Da Vinci Code, based on the novel of the same name by Dan Brown. In the film, religious leaders and professors are in a race to discover the secrets of an organization called the Priory of Sion. The biggest secret kept by this organization is supposedly that Jesus Christ and a woman whose name is recorded in the Bible as Mary Magdalene had a child, and that their family 55 line continues to this day. In a TV interview, Dan Brown stated that, in his book, "all of the art, architecture, secret rituals, secret societies, all of that is historical fact." However, while the Priory of Sion did exist, it's nothing like the one which is so central to The Da Vinci Code. The Priory of Sion was started in France in 1956 by a skillful liar named Pierre Plantard. Priory means religious house, and Sion was a hill in the town of Annemasse, where the Priory was started by Plantard and four of 60 his friends. At first, their group fought for housing rights for local people, and their offices were at Plantard's apartment. The organization promised to benefit the weak and the oppressed, and to do good in general. However, there was a darker side to the Plantard's Priory. Plantard actually hoped to use the Priory of Sion to claim to be a descendant of French kings. Between the years 1961 and 1984, Plantard created the enigma of a much more powerful Priory than his insignificant organization. First, in order to give the impression that the Priory began in 1099, Plantard and his friend Philippe de Cherisey created documents, called the Secret Dossiers of Henri Lobineau, and illegally put them into the National Library of France. Next, Plantard got author Gerard de Sede to write a book in 1967 using the false documents; the book became very popular in France. This phenomenon is similar to the popularity of The Da Vinci Code, where a book based on false information or speculation becomes popular. 70 Matters were complicated when in 1969, an English actor and science-fiction writer named Henry Lincoln read Gerard de Sede's book. Lincoln did not know of Plantard and his schemes, and may have been a victim of the hoax. He seemed to believe what he read, and jumped to even more wild conclusions, which he published in his 1982 book, The Holy Blood and the Holy Grail. He and his co-authors declared as fact that the Priory started in 1099; that its leaders included Leonardo Da Vinci, Isaac Newton, and Victor Hugo; that the Priory protects the descendants of Jesus 75 Christ and Mary Magdalene; and that these descendants ruled France from A.D. 447 to 751. All this was based on reading a novel based on the false facts from documents which were a hoax. Most modern historians do not consider Lincoln's book to be a serious work of history. How can we be so sure that Plantard created this hoax? Well, the best witness to a crime is the criminal himself. Over 100 hundred letters between Plantard, de Cherisey, and de Sede, discovered by researcher Jean-Luc 80 Chaumeil, show clearly that they were trying to pull an elaborate hoax. In fact, in the 1990s, Plantard got in trouble with the law, and his house was searched. Within it were found many false documents, most harmless, some of which said he was the true king of France. As a final embarrassment, Plantard had to swear in a court of law that the enigma of the Priory of Sion was the work of his imagination.
