Are your essay’s ideas conveyed clearly and articulately? Does your essay maintain proper focus on the issue, and is it well organized? Does your essay demonstrate proficiency, fluency, and maturity in its use of sentence structure, vocabulary, and idiom? Does your essay demonstrate command of the elements of Standard Written English, including grammar, word usage, spelling, and punctuation? ARGUMENT TASK: EVALUATION AND SCORING Evaluate your Argument task essay on a scale of 0 to 6 (6 being the highest score) according to the following five criteria: Does your essay identify and articulate the argument’s key unstated assump- tions? Does your essay explain how the argument relies on these unstated assumptions, and what the implications are if these assumptions are unwarranted? Does your essay develop its ideas in a clear, organized manner, with appropriate transitions to help connect ideas together? Does your essay demonstrate proficiency, fluency, and maturity in its use of sentence structure, vocabulary, and idiom? Does your essay demonstrate command of the elements of Standard Written English, including grammar, word usage, spelling, and punctuation? To help you evaluate your essay in terms of criteria 1 and 2, the following is a series of questions that identify five distinct unstated assumptions upon which the argument relies. To earn a score of 4 or higher, your essay should identify and explain at least three of these assumptions. Identifying and explaining at least four of the unstated assumptions would help earn you an even higher score. • Does the recommendation assume that Back to Basics is necessary to improve the students’ reading skills to the desired level? (Perhaps some other reading program or, for that matter, some other alternative, such as encouraging parents to read with their children or simply devoting more time during school to reading, would be as effective as Back to Basics—or possibly even more effective.) PART VI: Five Practice Tests560 . www.petersons.com • Would adopting the Back to Basics program in itself be sufficient to improve the students’ reading skills to the desired extent? (Unless the students are suffi- ciently attentive and motivated, and unless the teachers are sufficiently com- petent, the program might not be effective.) • Was the Back to Basics program the true reason for the improved reading skills that the company cites? (Perhaps the improved reading skills observed among children nationwide are attributable instead to a general increase in teacher salaries or to a new national children’s literacy campaign, to name just a few possibilities.) • Is Harper representative of the elementary schools throughout the nation that have adopted the program? (Perhaps this school’s students would not respond as well to the program’s methods as most students, for whatever reason.) • Is the evidence of the program’s effectiveness credible and unbiased? (The nationwide results of the Back to Basics program were reported by the program’s provider, who probably stands to profit by overstating the program’s effec- tiveness.) answers practicetest6 Practice Test 6 561 . www.petersons.com Verbal Reasoning 1.

B 1. The correct answer is (E). This is a “sign or manifestation of” analogy. To TREMBLE is to exhibit a certain physiological symptom, or manifes- tation, of FEAR; similarly, to weep is to exhibit a physiological manifes- tation of grief. Choice (D) is the sec- ond-best choice: an adoring person might follow the object of his or her adoration. But this manifestation is not physiological, nor is it as inexo- rable as trembling or weeping (as manifestations of fear and grief, respectively). 2. The correct answer is (D). This is a “function or purpose” analogy. A WATERMARK is a faint design embedded in PAPER in order to identify the paper’s maker. A badge is worn by an employee to identify both that employee and the employer—the “maker” of the employee. 3. The correct answer is (B). A key word in this sentence is “because,” which requires that what follows it must explain what precedes it. Profit potential would explain why drug companies persist in developing new drugs despite onerous (burdensome) government regulations. Choice (B) is the only one that expresses this idea. (The word dissuade means “dis- courage or persuade not to.”) 4. The correct answer is (B). PRO- PRIETY and decorum both mean “conformity to established standards of proper behavior or manners”; accordingly, lack of decorum is the opposite of propriety. 5. The correct answer is (A). SCI- ENTIAL means “of or having knowledge,” just the opposite of ignorant. 6. The correct answer is (C). CLOIS- TERED means “secluded or hidden away from the world.” A good antonym is gregarious, which means “living in a community.” 7. The correct answers are (i) lend credence and (ii) Specifically. Let’s start with the second blank. The second sentence tells us that “physical forces” (mentioned in the first sentence) include our own genetic makeup. In other words, the second sentence is bringing a general statement down to something more specific. So, the word Specifically provides a logical transition from the first (general) idea to the second (specific) one. Now consider the first blank. The new research seems con- sistent with the idea that human behavior is determined by physical forces beyond our control.
