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 from 24 to 30.    Duncan Phyfe made some of the most beautiful furniture found in America. His family name was originally Fife, and he was born in Scotland in 1768. In 1784, the Fife family immigrated to Albany, New York where Duncan’s father opened a cabinetmaking shop. Duncan followed his father’s footsteps and was apprenticed to a cabinetmaker. After completing his training, Duncan moved to New York City.    Duncan Fife was first mentioned in the 1792 NYC Directory as a furniture “joiner” in business at 2 Broad Street. Two years later, he moved, expanded his business, and changed his name to Phyfe. He was a quiet-living, God-fearing young man who felt his new name would probably appeal to potential customers who were definitely anti-British in this post-Revolutionary War period.    Duncan Phyfe’s name distinguished him from his contemporaries. Although the new spelling helped him better compete with French emigrant craftsmen, his new name had more to do with hanging it on a sign over his door stoop.    The artisans and merchants who came to America discovered a unique kind of freedom. They were no longer restricted by class and guild traditions of Europe. For the first time in history, a man learned that by working hard, he could build his business based on his own name and reputation and quality of work.    Phyfe’s workshop apparently took off immediately. At the peak of his success, Phyfe employed 100 craftsmen. Some economic historians point to Phyfe as having employed division of labor and an assembly line. What his workshop produced shows Phyfe’s absolute dedication to quality in workmanship. Each piece of furniture was made of the best available materials. He was reported to have paid $1,000 for a single Santo Domingo mahogany log.Phyfe did not create new designs. Rather, he borrowed from a broad range of the period’s classical styles, Empire, Sheraton, Regency, and French Classical among them. Nevertheless, Phyfe’s high quality craftsmanship established him as America’s patriotic interpreter of European design in the late eighteenth and early nineteenth centuries.           Although the number of pieces produced by Duncan Phyfe’s workshop is enormous, comparatively few marked or labeled pieces have been found extant. In antiques shops and auctions, collectors have paid $11,000 for a card table, $24,200 for a tea table, and $93,500 for a sewing tableAccording to the passage, which of the following does the author imply?

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 from 36 to 42.It used to be that people would drink coffee or tea in the morning to pick them up and get them going for the day. Then cola drinks hit the market. With lots of caffeine and sugar, these beverages soon became the pick-me-up of choice for many adults and teenagers. Now drink companies are putting out so-called "energy drinks." These beverages have the specific aim of giving tired consumers more energy. One example of a popular energy drink is Red Bull. The company that puts out this beverage has stated in interviews that Red Bull is not a thirst quencher. Nor is it meant to be a fluid replacement drink for athletes. Instead, the beverage is meant to revitalize a tired consumer’s body and mind. In order to do this, the makers of Red Bull, and other energy drinks, typically add vitamins and certain chemicals to their beverages. The added chemicals are like chemicals that the body naturally produces for energy. The vitamins, chemicals, caffeine, and sugar found in these beverages all seem like a sure bet to give a person energy.Health professionals are not so sure, though. For one thing, there is not enough evidence to show that all of the vitamins added to energy drinks actually raise a person’s energy level. Another problem is that there are so many things in the beverages. Nobody knows for sure how all of the ingredients in energy drinks work together. Dr. Brent Bauer, one of the directors at the Mayo Clinic in the US, cautions people about believing all the claims energy drinks make. He says, - It is plausible if you put all these things together, you will get a good result.” However, Dr. Bauer adds the mix of ingredients could also have a negative impact on the body. - We just don’t know at this point,” he says.The word -plausible‖ in the passage is closest in meaning to _______.

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 from 55 to 64.The New York Times is a daily newspaper published in New York City. For a long time, it has been a newspaper of record in the United State and one of the world’s great newspapers. Its strength is in its editorial excellence; it has never been the largest newspaper in terms of circulation.The Times was established in 1851 as a penny paper whose editors wanted to report the news in a restrained and objective fashion. It enjoyed early success as its editors set a pattern for the future by appealing to a cultured, intellectual readership instead of a mass audience. However, in the late nineteenth century, it came into competition with more popular, colorful, if not lurid, newspapers in New York City. Their publishers ran sensational stories, not because they were true, but because they sold newspapers. Despite price increases, the time was losing £1,000 a week when Adolph Simon Ochs bought it in 1896.Ochs built the Times into an internationally respected daily. He hired Carr Van Anda as editor. Van Anda placed greater stress than ever on full reporting of the news of the day, and his reporters maintained and emphasized existing good coverage of international news. The management of the paper decided to eliminate fiction from the paper, added a Sunday magazine section, and reduced the paper’s price back to a penny. In April 1912, the paper took many risks to report every aspect of the sinking of the Titanic. This greatly enhanced its prestige, and in its coverage of two world wars, the Times continued to enhance its reputation for excellence in world news.In 1971, the Times was given a copy of the so-called “Pentagon Papers,” a secret government study of U.S. involvement in the Vietnam war. When it published the report, it became involved in several lawsuits. The U.S. Supreme Court found that the publication was protected by the freedom-of-the-press clause in the First Amendment of the U.S Constitution. Later in the 1970s, the paper, under Adolph Ochs’s grandson, Arthur Ochs Sulzberger, introduced sweeping changes in the organization of the newspaper and its staff and brought out a national edition transmitted by satellite to regional printing plantsAccording to the passage, the Times has a national edition that is
