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:

Although management principles have been implemented since ancient times, most management scholars trace the beginning of modern management thought back to the early 1900s, beginning with the pioneering work of Frederick Taylor (1856-1915). Taylor was the first person to study work scientifically. He is most famous for introducing techniques of time and motion study, differential piece rate systems, and for systemtically specializing the work of operating employees and managers. Along with other pioneers such as Frank and Lillian Gilbreth, Taylor set the stage, labeling his philosophy and methods “scientific management”. At that time, his philosophy, which was concerned with productivity, but which was often misinterpreted as promoting worker interests at the expense of management, was in marked contrast to the prevailing industrial norms of worker exploitation. The time and motion study concepts were popularized by Frank and Lillian Gilbreth. The Gilbreths had 12 children. By analyzing his children’s dishwashing and bed making chores, this pioneer efficiency expert, Frank Gilbreth, hit on principles whereby workers could eliminate waste motion. He was memorialized by two of his children in their 1949 book called “Cheaper by the Dozen”. The Gilbreth methods included using stop watches to time worker movements and special tools (cameras and special clocks) to monitor and study worker performance, and also involved identification of “therbligs” (Gilbreth spelled backwards) - basic motions used in production jobs. Many of these motions and accompanying times have been used to determine how long it should take a skilled worker to perform a given job. In this way an industrial engineer can get a handle on the approximate time it should take to produce a product or provide a service. However, use of work analysis in this way is unlikely to lead to useful results unless all five work dimensions are considered, physical, psychological, social, cultural, and power.

Question: All of the following are true except ________.

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:

A survey is a study, generally in the form of an interview or a questionnaire, which provides information concerning how people think and act. In the United States, the best-known surveys are the Gallup poll and the Harris poll. As anyone who watches the news during presidential campaigns knows, these polls have become an important part of political life in the United States. North Americans are familiar with the many “person on the street” interviews on local television news shows. While such interviews can be highly entertaining, they are not necessarily an accurate indication of public opinion. First, they reflect the opinions of only those people who appear at a certain location. Thus, such samples can be biased in favor of commuters, middle-class shoppers, or factory workers, depending on which area the new people select. Second, television interviews tend to attract outgoing people who are willing to appear on the air, while they frighten away others who may feel intimidated by a camera. A survey must be based on a precise, representative sampling if it is to genuinely reflect a broad range of the population. In preparing to conduct a survey, sociologists must exercise great care in the wording of questions. An effective survey question must be simple and clear enough for people to understand it. It must also be specific enough so that there are no problems in interpreting the results. Even questions that are less structured must be carefully phrased in order to elicit the type of information desired. Surveys can be indispensable sources of information, but only if the sampling is done properly and the questions are worded accurately. There are two main forms of surveys: the interview and the questionnaire. Each of these forms of survey research has its advantages. An interviewer can obtain a high response rate because people find it more difficult to turn down a personal request for an interview than to throw away a written questionnaire. In addition, an interviewer can go beyond written questions and probe for a subject’s underlying feelings and reasons. However, questionnaires have the advantage of being cheaper and more consistent.

Question: The word “precise” 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:

One of the most interesting authors of the twentieth century, J. R. R. Tolkien, achieved fame through his highly inventive trilogy, The Lord of the Rings. Born in 1892, Tolkien received his education from Oxford and then served in World War I. After the war, he became a professor of Anglo-Saxon and English language and literature at Oxford University. Although published in 1965, the three books that comprise The Lord of the Rings were written in intervals from 1936 to 1949. This was mainly due to Tolkien’s responsibilities as a professor and the outbreak of World War II. By the late 1960s, this fascinating trilogy had become a sociological phenomenon as young people intently studied the mythology and legends created by Tolkien. The trilogy is remarkable not only for its highly developed account of historical fiction but also its success as a modern heroic epic. The main plot chronicles the struggle between good and evil kingdom as they try to acquire a magic ring that has the power to rule the world. The novels, which are set in a time called Middle Earth, describe a detailed fantasy world. Established before humans populated the Earth, Middle Earth was inhabited by good and evil creatures such as hobbits, dwarves, elves, monsters, wizards, and some humans. The characters and the setting of Middle Earth were modeled after mythological stories from Greece and Northern Europe. Although readers have scrutinized the texts for inner meaning and have tried to connect the trilogy with Tolkien’s real life experiences in England during World War II, he denieds the connection. He claims that the story began in his years as an undergraduate student grew out of his desire to create mythology and legends about elves and their language. Tolkien was a masterful fantasy novelist who used his extensive knowledge of folklore to create a body or work that is still read and enjoyed throughout the world today.

Question: What can we assume is NOT true about Middle Earth?
