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 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

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 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.

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.Colors are one of the most exciting experiences in life. I love them, and they are just as important to me as emotions are. Have you ever wondered how the two are so intimately related?Color directly affects your emotions. Color both reflects the current state of your emotions, and is something that you can use to improve or change your emotions. The color that you choose to wear either reflects your current state of being, or reflects the color or emotion that you need.The colors that you wear affect you much more than they affect the people around you. Of course, they also affect anyone who comes in contract with you, but you are the one saturated with the color all day! I even choose items around me based on their color. In the morning, I choose my clothes based on the color or emotion that I need for the day. So you can consciously use color to control the emotions that you are exposed to, which can help you to feel better.Color, sound, and emotions are all vibrations. Emotions are literally energy in motion; they are meant to move and flow. This is the reason that real feelings are the fastest way to get your energy in motion. Also, flowing energy is exactly what creates healthy cells in your body. So, the fastest way to be healthy is to be open to your real feelings. Alternately, the fastest way to create disease is to inhibit your emotions.What is the purpose of the passage?
