QUANTITATIVE SECTION 37 QUESTIONS • 75 MINUTES Directions for Problem Solving Questions: (These directions will appear on your screen before your first Problem Solving question.) Solve this problem and indicate the best of the answer choices given. Numbers: All numbers used are real numbers. Figures: A figure accompanying a Problem Solving question is intended to provide infor- mation useful in solving the problem. Figures are drawn as accurately as possible EXCEPT when it is stated in a specific problem that its figure is not drawn to scale. Straight lines may sometimes appear jagged. All figures lie on a plane unless otherwise indicated. To review these directions for subsequent questions of this type, click on HELP. Directions for Data Sufficiency Questions: (These directions will appear on your screen before your first Data Sufficiency question.) This Data Sufficiency problem consists of a question and two statements, labeled (1) and (2), in which certain data are given. You have to decide whether the data given in the statements are sufficient for answering the question. Using the data given in the statements plus your knowledge of mathematics and everyday facts (such as the number of days in July or the meaning of counterclockwise), you must indicate whether: (A) Statement (1) ALONE is sufficient, but statement (2) alone is not sufficient to answer the question asked; (B) Statement (2) ALONE is sufficient, but statement (1) alone is not sufficient to answer the question asked; (C) BOTH statements (1) and (2) TOGETHER are sufficient to answer the question asked, but NEITHER statement ALONE is sufficient; (D) EACH statement ALONE is sufficient to answer the question asked; (E) Statements (1) and (2) TOGETHER are NOT sufficient to answer the question asked, and additional data specific to the problem are needed. Numbers: All numbers used are real numbers. Figures: A figure accompanying a Data Sufficiency problem will conform to the information given in the question, but will not necessarily conform to the additional information in statements (1) and (2). Lines shown as straight can be assumed to be straight and lines that appear jagged can also be assumed to be straight. You may assume that positions of points, angles, regions, etc., exist in the order shown and that angle measures are greater than zero. All figures lie in a plane unless otherwise indicated. Note: In Data Sufficiency problems that ask you for the value of a quantity, the data given in the statements are sufficient only when it is possible to determine exactly one numerical value for the quantity.

QUESTIONS 6–8 ARE BASED ON THE FOLLOWING PASSAGE: Line The decline of the Iroquois Indian nations began during the American Revolution of 1776, when disagreement among them as to whether they should become involved in the war began to divide the Iroquois. Because of the success of the revolutionaries and the encroachment upon Iroquois lands that followed, many Iroquois resettled in Canada, while those who remained behind lost the respect they had enjoyed among other Indian nations. The introduction of distilled spirits resulted in widespread alcoholism, leading in turn to the rapid decline of both the culture and population. The influence of the Quakers impeded, yet in another sense contributed, to this decline. By establishing schools for the Iroquois and by introducing them to modern technology for agriculture and practice test Practice Test 3 481 5 10 15 20 www.petersons.com husbandry, the Quakers instilled in the Iroquois some hope for the future yet undermined the Iroquois’ sense of national identity. Ironically, it was Handsome Lake who can be credited with reviving the Iroquois culture. Lake, the alcoholic half-brother of Seneca Cornplanter, perhaps the most outspoken proponent among the Iroquois for assimilation of white customs and institutions, was a former member of the Great Council of Iroquois nations. Inspired by a near- death vision in 1799, Lake established a new religion among the Iroquois, which tied the more useful aspects of Christianity to traditional Indian beliefs and customs. 6. The passage mentions all the follow- ing events as contributing to the decline of the Iroquois culture EXCEPT: (A) new educational opportunities for the Iroquois people. (B) divisive power struggles among the leaders of the Iroquois nations. (C) introduction of new farming technologies. (D) territorial threats against the Iroquois nations. (E) discord among the nations regarding their role in the American Revolution. 7. Among the following reasons, it is most likely that the author considers Handsome Lake’s leading a revival of the Iroquois culture to be “ironic” because (A) he was a former member of the Great Council. (B) he was not a full-blooded relative of Seneca Cornplanter. (C) he was related by blood to an important proponent of assimi- lation. (D) Seneca Cornplanter was Lake’s alcoholic half-brother. (E) his religious beliefs conflicted with traditional Iroquois beliefs. 8. Assuming that the reasons asserted by the author for the decline of the Iroquois culture are historically representative of the decline of cultural minorities, which of the following developments would most likely contribute to the demise of a modern-day ethnic minority? (A) A bilingual education program in which children who are members of the minority group learn to read and write in both their traditional language and the language prevalent in the present culture. (B) A tax credit for residential- property owners who lease their property to members of the minority group. (C) Increased efforts by local government to eradicate the availability of illegal drugs. (D) The declaration of a national holiday commemorating a past war in which the minority group played an active role. (E) A government-sponsored program to assist minority- owned businesses in using computer technology to improve efficiency. 9. Over thirty million illegal immi- grants live in the United States, including greater than two million alone in California. (A) greater than two million alone in California. (B) in California greater than two million. (C) more in California than two million. (D) more than two million in California alone.
