SAT Practice 3: Finding Patterns in the Structure of the Passage 180 MCGRAW-HILL’S SAT of spontaneous generation arise from this mortal blow.” 50 All living organisms share a common ancestor, most likely a population of colonial microorganisms that lived almost 4 billion years ago. This common ancestor was itself the product of a long period of prebiotic 55 assembly of nonliving matter, including organic molecules and water, to form self-replicating units. All living organisms retain a fundamental chemical composition inherited from their ancient common 60 ancestor. 1. Throughout the passage, the word “spontaneous” can best be taken to mean (A) without reproductive elements (B) in a medium (C) unthinking (D) free-spirited (E) adult 2. In Pasteur’s experiment, why was the neck of the flask removed? (A) to allow the air to escape (B) to provide access to microorganisms (C) to kill any microorganisms that may be present (D) to permit the heating of the flask (E) to introduce fermentable material 3. In line 49, the word “mortal” most nearly means (A) human (B) impermanent (C) fatal (D) earthly (E) malicious The following passage, from a text on the principles of zoology, discusses theories of biogenesis, the process by which life forms are created. From ancient times, people commonly believed that life arose repeatedly by sponta- Line neous generation from nonliving material in addition to parental reproduction. For exam- 5 ple, frogs appeared to arise from damp earth, mice from putrefied matter, insects from dew, and maggots from decaying meat. Warmth, moisture, sunlight, and even starlight often were mentioned as factors that 10 encouraged spontaneous generation of living organisms. Among the accounts of early efforts to syn- thesize organisms in the laboratory is a recipe for making mice, given by the Belgian plant 15 nutritionist Jean Baptiste van Helmont (1648). “If you press a piece of underwear soiled with sweat together with some wheat in an open jar, after about 21 days the odor changes and the ferment. . . . changes the 20 wheat into mice. But what is more remarkable is that the mice which came out of the wheat and underwear were not small mice, not even miniature adults or aborted mice, but adult mice emerge!” 25 In 1861, the great French scientist Louis Pasteur convinced scientists that living organisms cannot arise spontaneously from nonliving matter. In his famous experiments, Pasteur introduced fermentable 30 material into a flask with a long s-shaped neck that was open to air. The flask and its contents were then boiled for a long time to kill any microorganisms that might be present. Afterward the flask was cooled and left 35 undisturbed. No fermentation occurred because all organisms that entered the open end were deposited in the neck and did not reach the fermentable material. When the neck of the flask was removed, micro- 40 organisms in the air promptly entered the fermentable material and proliferated. Pasteur concluded that life could not originate in the absence of previously existing organisms and their reproductive 45 elements, such as eggs and spores. Announc- ing his results to the French Academy, Pasteur proclaimed, “Never will the doctrine Cleveland Hickman, Larry Roberts, and Allan Larson, Integrated Principles of Zoology. © 2001 McGraw-Hill.

If both Pasteur’s conclusion that “life could not originate in the absence of . . . eggs and spores” (lines 42–45) and the statement, “This common ancestor . . . units” (lines 53–57) are true, then which of the following statements also must be true about “prebiotic assembly” (lines 54–55)? (A) It is not a “spontaneous” process. (B) It does not depend on sunlight. (C) It produces molecules unlike those in current life forms. (D) It occurs in the absence of water. (E) It occurs very quickly. 5. The author of this passage would likely agree with all of the following statements EXCEPT (A) Jean Baptiste van Helmont’s efforts to syn- thesize organisms were poorly controlled. (B) Life on earth began about 4 billion years ago. (C) Nonliving matter cannot form units that can reproduce themselves. (D) The chemical makeup of organisms must be fundamentally similar to that of their parents. (E) Carefully controlled experiments can disprove even widely held biological theories. 6. The theory of biogenesis described in lines 50–60 shares what common element with the theory of spontaneous generation described in lines 1–11? (A) a single common ancestor (B) water as an essential reactant (C) the process of fermentation (D) sexual reproduction (E) decaying organisms Answer Key 3: Finding Patterns in the Structure of the Passage 182 MCGRAW-HILL’S SAT 4.

The structure of the passage is the way that individual paragraphs work together to convey the central idea of the passage. 2. The paragraph 3. The introduction, the development, and the conclusion SAT Practice 3 1. A The theory of “spontaneous generation” is described as one in which life arises from substances that do not contain the reproductive elements of that life form. 2. B The important difference between the flask with the neck intact and the flask with the neck removed was the presence of microorganisms in the fermentable material. When the neck was removed, “microorganisms in the air promptly entered the fermentable material and proliferated.” 3. C The experiment, Pasteur claimed, “killed” the theory of spontaneous generation, so it dealt a fatal blow. 4. A The “prebiotic assembly” is said to occur over a “long period.” This must not be an example of “spontaneous generation,” that is, generation of life over a short period of time from nonliving material, because the theory of spontaneous generation has been disproven. 5. C The author clearly believes that van Helmont’s study was poorly controlled and that controlled experiments can disprove widely held theories because van Helmont’s theory was refuted when Pasteur imposed tighter controls. He also states that all living organisms derived from an ancestor “that lived almost 4 billion years ago” (lines 52–53) and that they “retain a fundamental chemical composition inherited from their ancient common ancestor” (lines 58–60). However, the author would not agree that “nonliving matter cannot form units that can reproduce themselves” because he describes just such matter in lines 53–57. 6. B The theory of spontaneous generation described in lines 1–11 mentions “damp earth,” “dew,” and “moisture” as “factors that encouraged spontaneous generation.” The theory of biogenesis described in lines 50–60 states that water is an essential element of prebiotic assembly. CHAPTER 4 / CRITICAL READING SKILLS 183 Lesson 4: Simplifying the Passage Simplify by Paraphrasing When you read, your brain is not a CD burner: It doesn’t just record all the information for perfect recall. You need to train your brain to process the information into simpler forms. This is called paraphrasing, summarizing paragraphs and passages in a few tidy words. Good readers constantly paraphrase paragraphs as they read. Don’t worry—it doesn’t waste time. With practice, paraphrasing will actually save you time on the reading section. Having the key ideas fresh in your mind helps you to zero in on the right answers. As you read SAT passages, practice paraphrasing each paragraph. You may want to write each summary in the margin. Be as concise as possible, but capture the key idea. For instance, “This paragraph is about dolphins and their intelligence” is a poor summary because it doesn’t capture the key idea, just the topic. A better summary is “Dolphins have communi- cation skills that other mammals lack.” If it’s relevant, make a quick note of how the paragraph relates to the previous paragraph. Does it provide an example of a concept described previously? Does it describe a situation that contrasts with the previous one? Simplify, but Don’t Oversimplify Avoid test-taking tricks that oversimplify SAT CR questions. Two of the most popular tricks in SAT courses and books are the “chuck the extremes” trick and the “don’t dis the minorities” trick. As with many simplistic shortcuts, they don’t work so well. They assume that the right answers to SAT questions are never “extreme,” particularly if they pertain to reading passages about minorities or women. So, they say, just eliminate any choices that take an extremely positive or negative tone, and eliminate all answers with a negative tone if the passage pertains to a minority or minority group “because the SAT will never disparage minorities.” The problem is that the SAT always knows how to thwart these shortcuts, to force students to read to get the right answer, rather than just apply a test-taking trick. For instance, the “minority” passage on the May 2006 SAT was a story about two Asian-American poets. Here are two of the questions: The tone of the characterizations quoted in lines 11–12 is best described as (A) morose (B) curious (C) sardonic (D) threatening (E) incredulous The tone of the statement in line 20 is best described as (A) impatient (B) apologetic (C) reflective (D) anxious (E) unconvinced Nationwide, thousands of students who had taken SAT courses were confident that they could “crack” these questions. Because the passage concerns American minorities, the tone of the correct answers must be positive, right? In question 12, the only choice with a positive tone is (B), and in question 13, the only one is (C). Easy! But wrong. Even a cursory reading would reveal the correct answers to be (C) sardonic and (E) unconvinced, respectively. Pretty negative, huh? Of course, SAT passages are not disparaging of minority groups, but this fact is not so easy to translate into a quick-and- easy test-taking trick as some would like you to believe. Simplify by Visualizing Visualization increases your brain’s ability to absorb information. After all, “a picture is worth a thousand words,” right? Visualizing as you read increases your interest as well as your retention. Visualizing a narrative is relatively simple because narratives contain characters and action. But how do you visualize an analysis or argument? • When reading an analysis, visualize the subject matter as best you can. For instance, if it’s about life in 15th–century Italy, picture a map of Italy, and visualize the people in dress of the times. If it’s about the discovery of a quasar, visualize the pulsing star and the astronomers gazing at it through tele- scopes, and perhaps visualize a timeline of the discoveries. • When you read an argument, visualize a battle with the author’s thesis on one side battling the opposing thesis. It’s very important to “see” the two sides. The explanations and examples are like “weapons” against the enemy. Concept Review 4: Simplifying the Passage 184 MCGRAW-HILL’S SAT 1. What should you visualize when reading a narrative? 2. What should you visualize when reading an argument? 3. What should you visualize when reading an analysis? 4. What questions should you answer at the end of each paragraph? Practice paraphrasing by writing a quick summary after each paragraph. 5. When examined closely, “raising standards” does not often have the effect of improving education, despite all the rhetoric. When this game—and it is largely a game—is played right, the statistics improve, and its proponents claim victory. But we can do all sorts of horrible things to students in order to improve educational statistics: kick out slow learners, encourage cheating, employ superficial tests that are easily coached but reflect no real academic skill, and so on. We think that by saying we’re “raising standards,” we are challenging our children more intensely, and thereby producing smarter and more mature kids. For the most part, it’s a con game, and we’re all being taken in. ___________________________________________________________________________________________________ ___________________________________________________________________________________________________ ___________________________________________________________________________________________________ 6. Art historians and aestheticians have long been confounded by Dadaism’s complexities and seeming paradoxes. Few seem able to express its real meaning. Dadaism imbues art with the outrageous and the whimsical, but it is a mistake to think that it is mere child’s play. It is a profound expression of art as life in the moment. Its works have sadly been lost on a public that expects erudition, archetypes, and allusions in its art, rather than the exu- berance of life that art should be. ___________________________________________________________________________________________________ ___________________________________________________________________________________________________ ___________________________________________________________________________________________________ CHAPTER 4 / CRITICAL READING SKILLS 185 SAT Practice 4: Simplifying the Passage decision to stay home. You just give a rea- son why you don’t want to, and your friend understands. 50 This convenience persuades us that teleological explanations are the best for analyzing human behavior. Furthermore, we resist mechanistic explanations of behavior because 55 they seem to deny another preciously guarded concept: free will. If our decision to stay home from a party could be explained in the same way that the action of an internal combustion engine can be explained, then doesn’t that 60 reduce us all to mindless machines? No: the mind’s understanding of the mind will always leave room for “free will,” what- ever that really means. Full understanding of a phenomenon depends on the mind’s ability 65 to detach from and observe it, and the mind can never fully detach from itself. This com- plication may imply that a full understanding of the human mind is impossible, but it does not imply that we must be satisfied with mere 70 teleology. Perhaps this will require an entirely new conception of psychology, but if psychology is to remain relevant, we have no other choice. 1. Which of the following is the best title for this passage? (A) Why Mechanism Should Replace Teleology (B) The Science of the Ancient Greeks (C) The Psychology of Wants and Needs (D) The Causes of Scientific Ignorance (E) Obstacles to a Full Understanding of the Mind 2. Which of the following is an example of a “teleological” explanation? (A) water evaporates because it absorbs heat (B) an engine works because it burns fuel (C) a bird sings because it likes the sound (D) a dog yelps because it perceives pain (E) a ball falls because a gravitational field pulls it The following passage discusses the philosophi- cal distinction between two methods of explaining scientific phenomena. As our theories about the world around us have evolved and have become more useful, they Line have become, almost without exception, less teleological and more mechanistic. A teleolog- 5 ical explanation of a phenomenon describes causes and effects in terms of desires or purposes: something happens simply because it serves a certain purpose, because it is “sup- posed” to happen, or because someone or 10 something “wants” it to happen. A ball falls to earth because, as it is in the air, it perceives that its more proper place is on the ground, and not because anything pushes it. Teleological explanations never survive as useful theories 15 because they are backward: they place the cause after the effect. A mechanistic explanation, on the other hand, requires that any discussion of causes and effects be restricted by the known laws of 20 how physical objects and substances interact as time moves forward. This is the language of the scientist. No right-minded chemist would say that trinitrotoluene explodes because it “wants to.” It does so because the presence of 25 heat and oxygen releases the potential energy stored in its bonds. Early scientific theories were almost exclu- sively teleological. If you could drive Socrates around in an SUV, he would be far more 30 likely to ask you about your vehicle’s nature, or its desires, or its soul than about how the engine worked, how the odometer received its information, or how the different buttons on the CD player produced their effects. It would 35 seem to him that he was in the belly of a metal- lic animal, or at least a possessed machine. Teleological explanations are convenient for explaining what people do, because most of us understand the concepts of “wants” and 40 “needs” far more deeply than we understand the mind’s mechanisms for processing information. If you only have three minutes to explain to your friend why you are not going to a party, you don’t very well have the knowledge, 45 not to mention the time or desire, to explain how your cerebral cortex processed the information and concepts associated with the © 2004 Christopher Black.

Which of the following best describes the characterizations of the “machine” in line 36 and the “machines” in line 60? (A) The “machine” is modern, but the “machines” are ancient. (B) The “machine” obeys mechanistic physical laws, but the “machines” do not. (C) The “machine” cannot be explained teleolog- ically, but the “machines” can. (D) The “machine” is simple, but the “machines” are not. (E) The “machine” is thought to have a soul, but the “machines” have had their souls diminished. 3. The reference to Socrates (lines 28–36) emphasizes the fact that he was (A) more influential than other Greek philosophers (B) fearful of complicated machines (C) concerned more with ethics than with physics (D) aware of the mechanistic laws of physics (E) inclined to explain phenomena in terms of purposes 4. In line 36, the word “possessed” most nearly means (A) owned (B) willful (C) purchased (D) determined (E) spontaneous 5. The fourth paragraph (lines 37–49) suggests that teleological explanations persist chiefly because they (A) are easier to use (B) are more logically consistent (C) agree with physical laws (D) deny free will (E) explain physical phenomena accurately CHAPTER 4 / CRITICAL READING SKILLS 187 Answer Key 4: Simplifying the Passage imagine watching a documentary about those animals as the “narrator” speaks. 4. What is the main idea of the paragraph? How does it relate to the previous paragraph? How does it support the central idea of the passage? 5. “Raising standards” can have many negative effects like cheating, unfairness, and superficial learning. 6. Dadaism is not silly or irrelevant; it is the expression of life in the moment. Concept Review 4 1. Visualize the characters and the action in vivid detail. Pay close attention to the conflict or problem in the story. 2. Visualize a physical battle between the opposing viewpoints in the argument. Imagine each rhetor- ical device as a weapon against the enemy. 3. Visualize the subject matter as best you can. If it is a historical analysis, try to visualize a map of the region being discussed, and visualize the people in dress of the times. If it is about animals, try to SAT Practice 4 1. A The passage compares mechanistic explanations to teleological ones and explains why mechanistic ones are “more useful.” Choices (B), (C), and (D) describe tasks that go far beyond what this passage accomplishes, and choice (E) describes an idea that is mentioned only in the last paragraph. 2. C “Teleological” explanations are those that “describe causes and effects in terms of desires or purposes.” Saying that a bird sings because it “likes the sound” implies that the bird’s action is caused by a desire. 3. E Socrates is said to “be far more likely to ask you about your vehicle’s nature, or its desires, or its soul than about how the engine worked.” This underscores the author’s belief that Socrates explained things in terms of their “purposes.” 4. B Socrates, the author tells us, would believe that the SUV possessed a soul, so the “possessed machine” is one with a living spirit and will. 5. A The fourth paragraph tells us that teleological explanations “are convenient,” and goes on to explain why people continue to use them. 6. E The “possessed machine” in line 36 is the SUV that Socrates would believe has a soul. The “mindless machines” of line 60 represent the conception of human beings that many would have if human behavior were explained “mechanisti- cally,” thereby removing (they would think) our free will and soul. Lesson 5: Connecting the Questions to the Passage 188 MCGRAW-HILL’S SAT Think of Your Own Answer First After answering the three key questions for yourself, attack the SAT questions by following these steps: 1. Read each question carefully, covering up the answer choices for now. 2. Translate it into a “stand-alone” question, if possible. 3. Formulate your own answer to the translated question. 4. Choose the best match among the choices. This strategy takes advantage of the work you’ve done answering the key questions, and keeps you from getting “talked into” wrong answers that only look good. For instance, a question such as “The passage suggests that most people do not notice bias in the media because . . .” can be translated into the open- ended question. “Why [according to this author] don’t people notice bias in the media?” Answer this question on your own, then find the best match among the choices. Know the 6 Question Types 1. Purpose questions ask why the author wrote the passage or used some particular word or lines, as in “The reference to the ‘tragedy’ (line 16) primarily serves to. . . .” These questions usually contain key phrases such as “in order to” or “primarily serves to.” To tackle these questions, first remind yourself of the purpose of the whole passage, and then of the paragraph, then of any line references. 2. Central idea questions ask you to summarize the central idea or make an inference based on the author’s position, as in “Which of the following is the best title of this passage?” or “With which of the following statements would the author most likely agree?” To tackle these questions, remind yourself of the central idea before checking the choices. 3. Secondary idea questions ask you to identify the main ideas of individual paragraphs rather than of the passage as a whole, as in “The ‘problems’ mentioned in line 56 are those of . . .” or “The third paragraph suggests. . . .” To tackle these questions, reread the specified lines—sticking to the specified lines and perhaps the sentence before—and summarize them before checking the choices. 4. Tone questions ask you about the attitude of the author or the tone of particular characterizations. To tackle tone questions, pay attention when the author is being funny, critical, condescending, or objective. 5. Word or phrase in context questions ask you what a particular word or phrase means in the context of a sentence. To tackle these questions, reread the specific sentence, translate the given word into your own word, and compare this to the choices. 6. Structure or device questions ask you about the rela- tionship between paragraphs or the author’s use of such devices as anecdotes, authoritative references, statistics, metaphors, counterexamples, and such. To tackle these questions, pay particular attention to such devices as you read analyses or arguments. Check the Line References Always carefully reread any words or lines the question refers to, with the question type in mind. For instance, if the question is a “purpose” question—using a phrase such as “in order to”— reread the words or lines asking, “What purpose does this word, phrase, or reference have in this discussion?” If it is a “secondary idea” question—using a word such as “suggests,” “rep- resents,” or “means”—reread the words or lines asking, “What does the author mean by that?” Use the “Sandwich Strategy” to Find the Answer Unlike questions on other SAT sections, CR questions do not go in order of increasing diffi- culty. Rather, they follow the order of the passage. Generally, the first questions are about the be- ginning of the passage, and the last questions are about the end of the passage. Use the “sandwich strategy” to answer questions without line references. For instance, if question 23 does not contain a line reference, but question 22 refers to line 15 and question 24 refers to line 25, then the answer to question 23 is probably “sandwiched” between lines 15 and 25!

What does it mean to translate SAT CR questions into “stand-alone” questions? 3. Why is it important to translate SAT CR questions into “stand-alone” questions whenever possible? 4.
