as your road map
Read the passage lightly and get a general idea of where the key information is and what is going on in the passage. This helps you figure out where to find the information as you begin to answer questions. Remember: Don’t sweat the details (yet). After reading a question, you can quickly revisit the passage to locate the details for answering the question correctly.
Grasping the gist of the passage
Understanding the main idea of the passage is the key to establishing the context of the paragraphs within. The main idea is typically the basis of one of the questions. If you can briefly sum up why the author is writing the passage, then you’ve not only developed a contextual understanding of the passage, but also answered one of the questions ahead of time.
Avoiding common traps
The folks who write the GRE are a tricky lot. They bait you with wrong but tempting answers, hoping you’ll bite. By recognizing these common traps, you have a better chance of avoiding them. Here are a few to watch out for:
Mixing main idea with details: Questions asking the main idea or primary purpose of the passage have answer choices that are true but aren’t the main idea. These are trap answers. For example, a passage may describe light pollution from cars or streetlights that obscures stars at night. The main idea isn’t the car headlights or streetlights: It’s the overall effect on nighttime visibility. Double-check the first and last sentences. Is the author asking for increased funding or a course of action? Is the passage challenging a common notion? If you know why the author is writing this, you’ll know the primary purpose of the passage and not be distracted by detail answers.One strategy is to work main idea or primary purpose questions last, especially with a long Reading Comprehension passage. Because you can go back and forth through the questions, you can work them in any order. As you answer the detail questions, you learn more about the main idea; then you can go back and answer that main idea question. Just don’t forget it and move forward, leaving that question unanswered.
Mixing cause-and-effect relationships: Answer choices typically mix up the cause-and-effect relationships of details in the passage. If the tide comes in because of the moon, for example, and this causes all the ships to rise, the question will check your understanding of what caused what to happen. Skim the passage for key words relating to the cause-and-effect described in the question. From the preceding example, look for the words moon, tide, and ships. Find the discussion of these events, and make sure the answer choice reflects the events discussed in the passage.
Mixing in your own knowledge: You may know something about the topic at hand. If you’re like most people, you add detail based on your own knowledge and expertise from other things that you’ve read. Sometimes, these details tempt you to choose an answer that’s true by your understanding but wrong per the passage. Be careful not to mix your own knowledge with what’s in the passage. I had a student who was a chemistry major work on a Reading Comp passage on chemistry, and she vehemently disagreed with what was in the passage. She was probably right — but she got all the questions wrong, based on what she thought it should be instead of what the passage said.
Answering the question yourself
One good way to dodge the answer-choice traps is to answer the question yourself first, before looking at the answer choices. Get a sense of what the right answer should be, then eliminate the wrong answer choices.
The right answer won’t match your own answer. That’s okay, it doesn’t have to. What it does is make the wrong answers clearly stand out, so that you can take them out of the running and focus on what remains. With a sense of what the right answer should be, three answers will stand out as not a chance and one will stand out as maybe. Go with the maybe: You can always return to it later.
Acing the Three Commonly Tested Reading Comprehension Passages
Reading Comprehension passages are typically based on either biological and physical sciences, social sciences, or humanities. Each of the following sections explains one passage type; presents a passage of that type along with sample questions, answers, and explanations to get you up to speed; and provides additional guidance and tips for successfully answering each question.
The biological and physical science passage
A biological or physical science passage is straightforward, giving you the scoop on something. It may be how stellar dust is affected by gravity, how to build a suspension bridge, or how molecular theory applies. The passage may be difficult to get through (because it goes into depth on an unfamiliar subject), so read it quickly for the gist and go back later for the details.
Here’s a science passage for you to practice on. Don’t forget to check the introduction paragraph for the overall gist of the passage and to look for the high-level contribution of each paragraph. If you know each paragraph’s purpose, you can quickly find the details when you need them.
Microbiological activity clearly affects the mechanical strength of leaves. Although it cannot be denied that with most species the loss of mechanical strength is the result of both invertebrate feeding and microbiological breakdown, the example of Fagus sylvatica illustrates loss without any sign of invertebrate attack being evident. Fagus shows little sign of invertebrate attack even after being exposed for eight months in either a lake or stream environment,
