Many people think you should just skim the passage or read the first lines of every paragraph, and not to read the passage. We believe this is an error: if you misunderstand the main idea of the passage, you will certainly get at least some of the questions wrong. Give the passage one good read, taking no more than 3 minutes to read all of the text. Do not read the passage more than once  that wastes too much time. If you have not understood it completely, try to answer the questions anyway. Note: this point of reading the whole passage is important for test-takers whose first language is not English, provided that they can read the passage in 3 minutes or less. #Make brief notes on the text on your scrap paper. As we will see below in greater detail, you should write down a couple of words on A) the Main Idea or Primary Purpose, B) Organization/Structure of the passage, and C) the Tone or Attitude of the author (if applicable). You just need a few words for each of these areas, and altogether it should not take longer than 30 seconds to write down. #Remember that the tone or attitude of the passage is usually respectful and moderate, never going to extremes of praise nor criticism. CAT obtains its Reading Comprehension passages from real articles about real academics and professionals. So the tone of the articles, even when there is criticism in the passage toward an academic or her work, is always balanced and moderate. In the same vein, articles that deal with minorities or ethnic groups are almost always positive and sympathetic. #Look out for structural words that tell you the important ideas or transitions in a passage. #Continue the Idea Words#Similarly#Moreover#Additionally#In the same way#Likewise##Conclusion Words#Thus#Therefore#Hence#So#In summary#In conclusion##Contradiction or Contrast Words#Neverthless#Nonetheless#However#But#Although#Though#Even though#Notwithstanding#Yet#Despite#In spite of#On the one handon the other hand#While#Unlike#Go back to the text of the passage for the answers. Many test- takers fail to return to the text of the passage to look for the correct answers. They rely solely on their memories and understanding of the passage after having read or skimmed it. Wrong.Go back to the text to look for information to answer the questions. Nine times out of ten, the answer lies within the passage. Of the 6 most important types of questions for Reading Comprehension, we will first look at Main Idea/Primary Purpose Questions, and the strategies we can use to answer them.Main Idea/Primary Purpose QuestionsMany people believe there is no difference between the main or central idea of the passage and the primary purpose of the author of the passage. This is simply not true. Let's take a look at the subtle but important difference between them:Main Idea#The question might look something like this:##"Which of the following best states the central idea of the passage?"#"Which of the following most accurately states the main idea of the passage?"#"Which of the following is the principal topic of the passage?"#"The main topic of the passage is...."##Primary Purpose#The question might look like this:##"The primary purpose of this passage is to..."#"The primary purpose of the passage as a whole is to..."#"The primary focus of this passage is on which of the following?"#"The main concern of the passage is to..."#"In the passage, the author is primarily interested in...."#"The passage is chiefly concerned with..." Strategy:Main Idea: Look in the first and last paragraphs for the main idea. Any conclusion words like

Main Idea/Title. The correct answer will say the same thing as it says in the text, but using different words. Re-read the first line of every passage, and the last line of the first and last paragraphs. This should give you the general structure or outline of the argument, with which you can answer the Title question. Make brief notes  a couple of words- regarding the Title on the text on your scrap paper while you read. After determining the general structure or content of the argument, eliminate answer choices that are too broad or too specific, i.e. answer choices that go beyond the content of the passage, or that deal with content only discussed in one paragraph of the passage. #PRIVATE##What would be an appropriate title for this passage?####PRIVATE##A)#Constructing The Tardis###B)#How To Make Space- Warping Material###C)#Bubbles In Space-Time###D)#Faster-Than-Light Travel: A Possibility?###E)#Debate On The Uses of Space Travel###ExplanationThis passage actually already has a title, "Warp Factor One". But we have to look for another title possibility, one that would be most like the Main Idea of the passage. We look at the first and last paragraphs, and since the Main Idea is that researchers now feel that faster-than-light travel maybe more than mere fantasy, we can find the correct answer choice. Does any answer choice corrspond to this idea? Yes- answer D, which is the correct answer.We can also find the correct answer through elimination. There is nowhere in the passage where it discusses building Dr. Who's Tardis (pity!), so we can eliminate A. Nor does it tell us how to make space-warping material. Eliminate B. While bubbles in space-time are discussed at some length in one of the paragraphs, we cannot say this is the main concern of the passage, and thus should eliminate C. And nowhere are the uses of space travel discussed, so discard E.Specific Detail or Target questions are probably the most common types of questions, and the easiest to answer. The question might look like this:#"According to the passage,...."#"The passage states that ...." StrategyThe Specific Detail or Target that we are looking for could be a Line Number, or a Name or Date. Go to the Line Number or Name or Date, and then read several lines above and below it. Find the answer choice that basically says the same thing as in the passage, though usually with different words or word order.#PRIVATE##According to the passage, Pfenning and Ford###PRIVATE##A)#demonstrated conclusively the impossibility of faster-than- light travel##B)#explored the possibility of bubbles that warp space##C)#supported the work of Alcubierre##D)#work at of the Institute for Theoretical Physics at the Catholic University of Leuven##E)#suggested that a warp drive was not physically possible##ExplanationThis is a Specific Detail/Target question, and therefore we look for the Name, Line Number, or Date that will help us. In this case, the detail consists of the names Pfenning and Ford. We scan the text, starting from the top of the passage, looking for the names Pfenning and Ford. We find them in only place, at the beginning of the second paragraph. We read a couple of lines above the names, and keep reading until a few lines after the names. It says "But in 1997 Michael Pfenning and Larry Ford at Tufts University in Medford, Massachusetts, apparently killed this ingenious idea by showing that it needed far more than the entire energy content of the Universe to work (This Week, 26 July 1997, p 6)". The line after that says the research of another physicist then resurrected the possibility of FTL travel, negating the implications of the research of Pfenning and Ford. Now we can answer the question. Do any of the answer choices match the information given around the target area? Yes- E.Let's also eliminate. If we re-read what the passage says about Pfenning and Ford, we can eliminate B, C, and D. None of them are supported by the information in the passage, so let's eliminate all of them without wasting too much time and with a minimum of fuss. A is tougher to eliminate. From the sentence that mention Pfenning and Ford, it seems their work does rule out the possibility of a space-warp drive. But if we read the next line, it says another researcher said it was indeed possible. So the Pfenning and Ford could not have "conclusively" demonstrated the impossibity of the FTL drive.This is probably the most difficult type of Reading Comprehension problem. The question might look like this:#"It can be inferred that the author makes which of the following assumptions?"#"Which is an assumption underlying the last sentence of the passage?"#"Which of the following, if true, would most strengthen the hypothesis mentioned in lines 17-19?"#"With which of the following statements regarding chaos theory would the author be most likely to agree?" Strategy:First, treat this type of problem as a Specific Target

question. Look for a target in the question, find it in the text, and then look above and below it. Often you do not have to infer very much, the answer remains within the text. If the answer must be inferred and is not stated explicitly within the text, then choose the answer choice that can be inferred or assumed from the information given. Again, you should not have to infer very much  only one or two logical steps removed from the information in the passage. Make sure that the answer choice you decide on does not violate or contradict the Main Idea of the passage - if it does, the answer choice is probably wrong. #PRIVATE##It can be inferred that a house with the propeties of the bubble mentioned in the passage####PRIVATE##A)#would be larger on the inside than on the outside###B)#could move faster than the speed of light###C)#might be very energy efficient###D)#could move through time###E)#would eventually fold in on itself and be destroyed###ExplanationFirst, let's try to deal with this question as a Specific Target problem. Is there a target in the question? Yes  the bubble. The bubble is first mentioned at the end of the second paragraph, and then discussed at length throughout the third paragraph. Remember, we have to look above and below that target area (as well as read the target area again), so quickly go through the second, third, and first part of the fourth paragraph. When you are finished, look at the answer choices. Can any of them be inferred from the information given in the target area? Well, we could eliminate C, D, and E for simply not being supported by the information given in the passage. B  maybe, but a house moving through time seems pretty silly. But in the fourth paragraph the author talks about the Tardis, "which looked like a police box but had a spacious interior". Big on the inside, small on the outside. Is that like our house? Yes- answer A. As well, we can choose A because it does not go against or contradict the Main Idea in this case, which if it had, would have made it necessary to eliminate. So choose A.The question might look like this:# "The author's attitude towards Morgan's theory could best be described as one of ..." Strategy:Look for descriptive words, adjectives or adverbs, that could tell you the author's attitude. For example, the words unfortunately or flaw suggest a negative connotation, while strength or valuable emphasize the positive. Make brief notes  a couple of words- regarding the Tone of the text on your scrap paper while you read. Additionally, keep in mind that the author's attitude toward a theory, book, or ethnic group will almost always be respectful, even when somewhat critical.#PRIVATE##The author's attitude towards Miguel Alcibierre's theory could best be described as one of ####PRIVATE##A)#admiration###B)#mild skepticism###C)#unbridled scorn###D)#dismay###E)#complete objectivity###ExplanationSince this is a Tone/Attitude question, we must look in the passage for descriptive words that tell us what the author thinks of Alcibierre and his theory. In the second paragraph the author call's Alcibierre's theory "this ingenious idea". This is positive, and the only positive answer choice is A. A is the correct answer. As well, if we could not find the tone so easily, we could also eliminate C and D at the very least, for being too extreme.The question might look like this:# "Which of the following best describes the organization of the passage?"#"Which of the following best describes the organization of the first paragraph of the passage?"#"One function of the third paragraph is to...." Strategy:Re-read the first line of every passage, and the last line of the first and last paragraphs. This should give you the general structure or outline of the argument, with which you can answer the question. Remember to make brief notes about the structure of the text on your scrap paper. If you are looking for the organization of one paragraph, read the first and second sentence of the paragraph. That will give you a rough idea of what is the structure or organization of the paragraph.#PRIVATE##Which of the following best describes the organization of the second paragraph of the passage?####PRIVATE##A)#Two investigations that support Alcubierre's theory are introduced###B)#Possible objections to the uses of the warp drive are present, and then refuted###C)#An objection to the practicality of the theory is raised, and then another work is cited to shore up the applicability of the original theory###D)#A work of theoretical physics that supports Alcubierre's theory is raised, and then another that refutes it is presented###E)#Alcubierre's theory is analyzed by a panel of several eminent physicists###ExplanationRead the first sentence of the paragraph: "But in 1997 Michael Pfenning and Larry Ford at Tufts University in Medford, Massachusetts, apparently killed this ingenious idea by showing that it
