  • 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:

    Walt Disney was born in 1901 in Chicago, but soon moved to a small farm near Marceline, Missouri. From this rural and rather humble beginning, he later became one of the most famous and beloved motion-picture producers in history. Although he died in 1966, his name and artistic legacy continue to influence the lives of millions of people throughout the world.

    After several years of barely making ends meet as a cartoon artist operating from his Los Angeles garage, Disney had his first success in 1928, with his release of a Mickey Mouse cartoon. Throughout the next decade, he continued to produce a number of cartoons, and develop more of his highly profitable and enduring creations, such as Donald Duck and Pluto. In the late 1930s, he issued a full-length cartoon film. Snow White became an instant commercial and critical success. This was only the first of many films, both animated and not, produced by Disney and his studio.

    But as renowned as Disney name is for cartoons and movies, it is probably best known for a string of spectacular amusement and theme parks. Starting with California's Disneyland in 1955 and culminating with the fantastically successful Disney World and EPCOT Center in Florida, Disney became a household name. In recent years, the theme park concept became international, with openings in Tokyo and Paris. With the continuing success of Disney, the creation of future theme park is under discussion.

    Question 38: According to the passage, which of the following is true?

    Question 39: The word "enduring" in bold in paragraph 2 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 following questions:

    During the 19th century, women in the United States organized and participated in a large number of reform movements, including movements to reorganize the prison system, improve education, ban the sale of alcohol, grant rights to people who were denied them, and, most importantly, free slaves. Some women saw similarities in the social status of women and slaves. Woman like Elizabeth Cady Stanton and Lucy Stone were feminists and abolitionists who supported the rights of both women and blacks. A number of male abolitionists, including William Lloyd Garrison and Wendell Phillips, also supported the rights of women to speak and to participate equally with men in antislavery activities. Probably more than any other movement, abolitionism offered women a previously denied entry into politics. They became involved primarily in order to better their living conditions and improve the conditions of others.

    When the civil war ended in 1865, the Fourteenth and Fifteenth Amendments to the Constitution adopted in 1868 and 1870 granted citizenship and suffrage to blacks but not to women. Discouraged but resolved, feminists worked tirelessly to influence more and more women to demand the right to vote. In 1869, the Wyoming Territory had yielded to demands by feminists, but the states on the East Coast resisted more stubbornly than before. A womens suffrage bill had been presented to every Congress since 1878, but it continually failed to pass until 1920, when the Nineteenth Amendment granted women the right to vote.

    Question: What is the word primarily 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:

    Esperanto is what is called a planned, or artificial language. It was created more than a century ago by Polish eye doctor Ludwik Lazar Zamenhof. Zamenhof believed that a common language would help to alleviate some of the misunderstandings among cultures.

    In Zamenhofs first attempt at a universal language, he tried to create a language that was as uncomplicated as possible. This first language included words such as ab, ac, eb, be and ce. This did not result in a workable language in that these monosyllabic, though short, were not easy to understand or to retain.

    Next, Zamenhof tried a different way of constructing a simplified language. He made the words in his language sound like words that people already knew, but he simplified the grammar tremendously. One example of how he simplified the language can be seen in the suffixes: all nouns in this language end in -o, as in the noun amiko, which means friend, and all adjectives end in -a, as in the adjective bela, which means pretty". Another example of the simplified language can be seen in the prefix mal-, which makes a word opposite in meaning, the word malamiko therefore means enemy, and the word malbela therefore means ugly in Zamenhofs language.

    In 1887, Zamenhof wrote a description of this language and published it. He used a pen name, Dr. Esperanto, when signing the book. He selected the name Esperanto because this word means a person who hopes in his language. Esperanto clubs began popping up throughout Europe, and by 1950, Esperanto had spread from Europe to America and Asia.

    In 1905, the First World Congress of Esperanto took place in France, with approximately 700 attendees from 20 different countries. Congresses were held annually for nine years, and 4,000 attendees were registered for the Tenth World Esperanto Congress scheduled for 1914, when World War I erupted and forced its cancellation.

    Esperanto has had its ups and downs in the period since World War I. Today, years after it was introduced, it is estimated that perhaps a quarter of a million people are fluent in it. This may seem like a large number, but it is really quite small when compared with the billion English speakers and billion Mandarin Chinese speakers in todays world. Current advocates would like to see its use grow considerably and are taking steps to try to make this happen.
