68 Two Success Steps for Misplaced Sentences 1. Read the passage to determine the main idea. 2. Be suspicious of any sentence that has nothing to do with the main idea. 1. Which of the following best describes the struc- ture of the passage? a. The passage begins with a hypothesis, and then gives an explanation and support for this theory. b. The passage starts with a main idea, gives an example, and then draws a conclusion. c. The passage opens with an introduction to the topic, then gives a more detailed account of the topic. d. The passage begins with a statement, supports that statement with research, and gives real life examples. e. The passage begins with an event and then continues the narrative. 2. Which of the following would be the best outline for the passage? a. I. Statement II. Facts III. Quotations b. I. Theory II. Practices c. I. Research II. Discussion III. Example d. I. Question II. Answer III. Support e. I. Quote II. Thesis III. Examples Answers Here’s how you could use the six Success Steps to answer question 1. 1. It seems as though the passage is about students of different ages and abilities learning together. 2. The first paragraph tells why and the second tells how students come to be in groups of mixed age and ability. 3. The first sentence states a fact. The other sen- tences in the paragraph seem to cite research. It doesn’t say so at first, but later it says, “Researchers also found . . .” which implies that research was involved in the theories before that sentence. 4. Answers c and e are out. The passage does not give much introduction to the topic, and does not start with an event. 5. The next sentences support the topic sentence with research. The answer must be d. 6. For this question, you don’t need to use this hint. If you use the same method to answer question 2, you will quickly eliminate answers d and e on the basis of the first few sentences.You eliminate a because there are no quotations. You are left with b and c, which are very close. Answer c contains a vague word, discussion, which could be almost any kind of structure. Answer b is more precise. The first paragraph in the passage gives the theory, and the second gives the application of the theory. The better answer is b. Misplaced Sentences You may be asked to find the sentence that does not logically flow, or that is not necessary to the purpose of the passage. Such questions often start out like this: ■ Which sentence, if omitted from the passage, would be least likely to interrupt the sequence of ideas? 69 1. While reading or skimming the passage, notice the general topic. 2. Go through the answer choices. Cross out any that are completely off the topic. 3. Cross out any answer choices that are too broad for a short passage. (“The constellations” might be the sub- ject of a book, but not the main idea for a paragraph or two.) 4. Eliminate any answer that is on the general topic, but not the specific topic of the passage. 5. Cross out any that only deal with one sentence of a paragraph, or one paragraph of a longer passage. 6. If you are still left with two answers that seem to fit most of the sentences in the passage, then choose the one that is most precise or specific. 7. If you have crossed them all out, check the choices again. Carefully try to decide whether there is another meaning to any of the answer choices. If you’re still stumped, go back to the answer that was the most spe- cific and seemed to cover more of the passage than the others. Seven Success Steps for Simple Main Idea Questions ■ Which of the following is least relevant to the main idea of the passage? Where to Find Misplaced Sentences You will usually be directed to a particular paragraph. If the first sentence states the main idea of the para- graph, it is unlikely to be the misplaced sentence. Check all others. Sample Passage and Question The goal is to discover the sequence of bases in the DNA. If this is a mitochondrial DNA fragment, the sequence will be like the person’s mother and maternal relatives. The DNA is divided down the center like unzipping a zipper. Heat is used to cause the division. Only one half (side of the zipper) is used. The sequence of bases will be discovered by recreating the other half. (This passage will be continued in the next section, Reading 3.) 3. Which of the sentences in the first paragraph is least relevant to the main idea of the paragraph? a. Heat is used to cause the division. b. The DNA is divided down the center like unzipping a zipper. c. The goal is to discover the sequence of bases in the DNA. d. If this is a mitochondrial DNA fragment, the sequence will be like the person’s mother and maternal relatives. e. Only one half (side of the zipper) is used. Answer The passage describes the process of reading DNA. The second sentence has nothing to do with the process. It should have been placed in a paragraph that discussed vocabulary. The answer is d. Preparing for Organization Questions To further prepare for the test, as you read any book, magazine, or paper, you might want to take note of dif- ferent ways paragraphs are structured and how sen- tences follow in a logical sequence.  Reading 3: Unmasking the Main Idea Main idea questions can be put in three categories. The first asks for a simple sentence or title that includes the main topic of the passage. The second asks questions about the author and what the author had in mind. Then there are those that ask for a paraphrase of all the main ideas in the passage. Pure and Simple Simple main idea questions take a variety of forms: ■ What is the main idea of the passage? ■ The best title for this passage would be . . . ■ What is the theme of the passage? ■ The central thought of the passage is . . . How to Find Main Idea Answers in the Passage To answer main idea questions, you sometimes do not have to read the whole passage. Often the main idea is stated at the beginning or end of the passage. Some- times you can glean the main idea by paying attention to the topic sentences of each paragraph of the passage. Sample Passage and Question This passage continues the passage on DNA that you began in the previous section. The goal is to discover the sequence of bases in the DNA. If this is a mitochondrial DNA fragment, the sequence will be like the person’s mother and maternal relatives. The DNA is divided down the center like unzipping a zipper. Heat is used to cause the division. Only one half (side of the zipper) is used. The sequence of bases will be discovered by recreating the other half. The next goal is to use the half of the DNA which was saved to reconstruct the other half. This process will show the sequence of bases. Bases A and T always bind to each other. Bases C and G always bind to each other. The idea is to put one-half of a DNA strand in a test tube with some free bases and an enzyme that causes the free bases to attach to the half strand—rezipping the zipper. Modified bases are also added so that the location of that base on the “zipper” can be marked. In this way, the sequence of bases can be discovered. Each test tube contains thousands of copies of the saved half of the DNA strand, and a radioactive primer which will attach at the start location of every strand so that all operations start at the same place on every strand. Also included are DNA polymerase, which is an enzyme that acts as a “glue” to attach the free bases to the half DNA strand, and all four bases, which are free and unattached. There is also a modified base— each test tube has a different base which has been modified to act as a marker during reconstruction. At the end of the process, thousands of recon- structed strands will be in each test tube. Some of these strands will be complete, but some of them will have been terminated by a modified base so they will be shorter. All of them will have the same sequence of bases but will terminate at different positions where A is found. The reason that some of the strands did not terminate at base A is that a nor- mal instead of a modified base A attached at some of the base A locations. There is a test tube for each base. Therefore, there are reconstructed strands which terminate with C in the test tube with mod- ified C bases, strands which terminate with G in the test tube with modified G bases, and strands which terminate with T in the test tube with modified T bases. The four test tubes are used in order to tell the difference between bases since the strands and bases all look alike. However, the same test can be done in one test tube if fluorescent dyes are used to tag the modified bases. –CBEST MINI-COURSE– 70 1. Which of the following best describes the main topic of the passage? a. DNA can be linked to clues in a criminal investigation. b. Learning about the genetic code is important. c. The role of modified bases is part of reading DNA. d. Dyes are used to tell the difference between bases. e. Reading base A strands is done at the end of the process. Answer Use the Success Steps to help you answer the question. 1. The general topic seems to have to do with the DNA strands in the test tube and some marked ends that help people read them. 2. It looks as though a is off the topic because the passage does not mention criminal investigations. 3. Answer b seems too broad. 4. There don’t seem to be any answer choices that are on the general topic but not the specific topic. 5. Answers d and e have to do with only one part of the passage. You don’t have to use steps 6 and 7, because you have one answer left: choice c seems to fit. Sample Passage and Question Try your hand at another passage and main idea question. Successful programs make the extended-time cur- riculum challenging but not overwhelming. Research indicates that a challenging curriculum should accommodate individual student needs, coordinate with other instruction, and focus on more than remedial work. For example, the TAP Summer Youth Employment Program, which serves a large number of students living in housing proj- ects, teaches basic skills that students need for communicating with employers and co-workers, and it also provides students with the challenge of putting these skills to use while working in their communities. 2. Which of the following would be the best title for the passage? a. Appropriately Challenging Curriculum b. Successful Programs c. Individualized Learning d. Curriculum Innovation e. The TAP Summer Youth Employment Program Answer Again, apply the seven Success Steps. 1. The passage seems to be about the curriculum for a program outside of school. 2. It looks as if all the choices are on the general topic. 3. Answers b and d are too broad. 4. Answer c is on the general topic, but not on the subject of the paragraph. 5. Answer e has to do with only a part of the passage. The paragraph is mostly about appropriately challenging curriculum. Therefore, answer a would make the best title. Once again, you did not have to use steps 6 and 7. Perfect Paraphrases There will probably be at least one question that asks you to paraphrase the entire passage. Paraphrase ques- tions are the most troublesome of all the main idea questions because the choices are so long. Realize, however, that the test makers had to make four of the choices wrong in some way. Your task is to discover the errors. –CBEST MINI-COURSE– 71 72 1. Read or skim the passage, noting or underlining main ideas as they flow from one to the other. 2. Look for phrases that restate the main ideas you underlined. 3. Eliminate answers that contain phrases that contradict ideas in the passage. 4. Eliminate answers that are off the topic or only deal with part of the passage. 5. Eliminate answers that state one or more ideas that the author has not mentioned. 6. If left with two choices, choose the most complete one. 7. If you have eliminated them all, take the paraphrase that contains the most main ideas without adding new ideas. Seven Success Steps for Paraphrase Questions Paraphrase questions tend to start out like this: ■ Which of the following best paraphrases the ideas in the passage? ■ The best summary of the passage is . . . ■ Which of the following is the best summation of the ideas in the passage? ■ Which of the following best restates the main ideas of the passage? How to Find Paraphrase Answers in the Passage The main ideas of the passage can be found in each of the paragraphs, or in sections of the paragraphs. If you can follow the way the author has logically arranged the passage, you are more likely to find the correct answer to a paraphrase question. Sample Passage and Question Extended-time programs often feature innovative scheduling, as program staff work to maintain participation and respond to students’ and parents’ varied schedules and family or employment com- mitments. Offering students flexibility and some choice regarding when they participate in extended learning may be as simple as offering homework sessions when children need them most—after school and before dinner—as do Kids Crew and the Omaha After-School Study Centers. Or it may mean keeping early and late hours to meet the child care needs of parents who work more than one job or support extended families, as does Yuk Yau Child Development Center. Similarly, the Florida Summer Institute for At-Risk Migrant Students is a residen- tial program so that students’ participation does not disrupt their migrant families’ travels. 3. Which of the following paraphrases best summa- rizes the passage above? a. After-school programs should help children finish their homework after school. b. Kids Crew and other programs meet the needs of children. c. There are several ways to schedule programs outside school time to meet the needs of stu- dents and families. d. Extended-time programs can be innovative, and Yuk Yau Child Development Center is an example of this. e. Extended hours may need to be late or early to accommodate needs. Answer Walk through the steps: 1. The flow goes like this: innovative scheduling— family needs—examples: after school, early and late care, residential. 2. Answers a, c, d, and e have words and ideas noted in step 1. 3. None of the answers are contrary to the passage. That tactic is usually used with persuasive passages. 73 1. For author-purpose questions, eliminate answers that do not match the general topic. If it is a scientific pas- sage, the author is probably objectively trying to disseminate information, so you should eliminate answers that suggest the author is trying to change the reader’s behavior in any way. If it is a persuasive paragraph, however, the author is not just simply conveying information. For questions on the author’s intended audi- ence, eliminate audiences that are significantly less or more technical than the author’s style. 2. Eliminate answers that say the opposite of what the author is trying to say. 3. Look for a climax in the passage, a sentence or two that describes the author’s purpose or audience. Then look for an answer that says the same thing in different words. Also, be on the lookout for clue words that could hint at the audience. 4. Look for words that indicate a change or shift in the author’s meaning. Sometimes the author’s purpose will follow words such as “however,” or be found somewhere in sentences beginning with words like “although” or “instead of.” 5. If you are looking for an author’s tone, put the answer choices in order from very negative to very positive. Look for adjectives that describe the way the author feels about a topic; then look for synonyms or the same tone in the answer choices. 6. If you are left with two choices, look at the topic of the passage and decide what might be an appropriate response to the topic. If the topic discusses a dangerous future situation, an appropriate response of the author might be a warning. 7. Avoid controversy. Test makers will probably not create a correct answer that displays intolerance or pro- motes illegal activities. Seven Success Steps for Author Questions 4. The answers are all on the topic, but a, b, and e only deal with part of the paragraph. 5. All the ideas are in the passage. 6. You are left with answers c and d. Answer d only mentions one example and the passage gives three. Answer c does not mention any examples specifically, but includes all the examples as well as the idea of the paragraph. You can conclude that the answer is c, and you don’t have to use step 7. Preparing for Main Idea Questions For extra practice, check out all the test books you can from the library that have a reading comprehension section and answer as many main idea questions as you can until you feel very confident.  Reading 4: About the Author Most passages were not written to torture test takers. Authors write to communicate; that is, they want you to understand their ideas and arguments. To that end, they usually will try to write as clearly and logically as possible. To read these passages efficiently, therefore, you need to get involved with the author in the subject. Give this author your undivided attention and try to understand what the author took the time and trouble to write. As you read, ask yourself these questions: ■ Who is this person? ■ Can I detect anything about the author? ■ From what perspective does the author write? ■ How does the author think? . to make four of the choices wrong in some way. Your task is to discover the errors. CBEST MINI-COURSE– 71 72 1. Read or skim the passage, noting or underlining main ideas as they flow from one. answers c and d.
