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.

A reliable survey indicates that college graduates change employers four times on average during the first ten years after college gradua- tion. Therefore, in order to avoid employee turnover, business adminis- trators in charge of hiring new employees should favor job applicants who obtained college degrees at least ten years earlier. The advice about how to avoid employee turnover rests on which of the following assumptions? (A) Employee turnover among businesses that hire employees without college degrees is greater than among businesses that hire only employees with college degrees. (B) Job changes within the same company are less common than job changes from one employer to another. (C) Employees who graduated from college at least ten years ago change employers less fre- quently on average than other employees. (D) Most employees who leave their jobs do so upon either request or demand of their employers rather than by their own initiative. (E) The survey excluded college graduates who interrupted their vocational careers to pursue advanced academic degrees. 4.

Driving excessively fast has been demonstrated to decrease the number of miles one can drive per gallon of fuel. Gary has recently been experi- encing a decrease in mileage per gallon of fuel while driving his car. This clearly proves that Gary has been driving excessively fast lately. Which of the following statements, if true, would most seriously weaken the conclusion about Gary’s driving? (A) Recently Gary’s speedometer has been indicating the speed of his car as lower than the car’s actual speed. (B) Recently Gary has been driving more miles per day on average than before he began experienc- ing a decrease in fuel mileage. (C) Other tests have shown that a car’s speed affects fuel mileage more than any other single factor. (D) Before Gary began driving excessively fast his speedometer over-represented his car’s actual speed. (E) Recently the tires on Gary’s car have been losing air pressure, and low tire air pressure is known to lower fuel mileage. practice test Practice Test 5 571 www.petersons.com 6. Expensive television advertising campaigns clearly help political candidates win elections, as evidenced by the fact that, in most political elections, the candidate with the most campaign money ultimately wins. Which of the following, if true, would provide most support for the argument above?

(E) Nearly any political candidate can afford to wage some type of television advertising campaign. QUESTIONS 7–9 ARE BASED ON THE FOLLOWING PASSAGE: Line The twentieth-century discovery of Archaeans, which did not fit into the kingdom classification scheme for biological life, led to the creation of the domain classification level, above the kingdom level. This new level included the new domain Archaean. Prior to the discovery of Archaeans, it had been generally accepted that no life could exist in temperatures much hotter than 60 degrees centigrade. This limit was set because it was thought that the molecular integrity of vital cellular components could not be maintained beyond such temperatures. The thermal capacity of cellular life, it was believed, was a fixture across all biological organisms. Archaeans, in recent decades, have repeatedly demonstrated that the previously maintained thermal threshold for life was far too low. So-called extremophilic Archaeans have been discovered to thrive in temperatures as high as 160 degrees centigrade. Such discoveries have required a broadening of biology’s conceptions concerning what environ- ments are hospitable to life. 7. The author of the passage implies that extremophilic Archaeans (A) are able to maintain molecular integrity of cellular components past what was formerly ac- cepted as the thermal threshold of life. (B) have been known to exist in moderate environments for some years, but their extremo- philic properties have only recently been discovered. (C) are able to live and thrive in temperatures higher than 160 degrees centigrade. (D) were responsible for the development of a distinct kingdom in the classification scheme for biological life. (E) are the oldest known form of multi-cellular biologic life. 8. The passage’s author suggests that the “thermal threshold” (line 21) is (A) the thermal capacity of extre- mophiles. (B) the critical point temperature at which the metabolic pathways of extremophiles become functional. (C) an environmental extremity indicator. (D) the temperature at which the molecular integrity of cellular components of an organism are compromised. (E) a biological constant across all of nature. 572 PART VI: Five Practice Tests 5 10 15 20 25 www.petersons.com . question.) This question presents a sentence, all or part of which is underlined.
