With regard to the GMAT, raw intellectual horsepower helps, but it is not everything. In this blog series, Manhattan GMAT’s Stacey Koprince teaches you how to perform at your best on test day by using some common sense.
Part 1 of this series covered how to read Reading Comprehension (RC), and Part 2 introduced the first two major question types: Main Idea and Specific Detail. Start with those posts and then continue with this post.
In this section, we are going to talk about two big things: how to handle inference questions and how to analyze RC problems in general (you can then use these techniques on any question type).
Inference questions ask about specific details in the passage, but they add a twist: we have to deduce something that must be true, given certain facts from the passage.
For example, if I tell you that my favorite type of book to read is biography, what could you deduce?
Watch out for the trap: do not use your “real world” conclusion-drawing skills. In the real world, you might conclude that I like reading books in general or perhaps that I am interested in history or maybe that I am a nerd. (Really?Biographies are my favorite?) These things do not have to be true, though.
What has to be true? I do not like fiction as much as I like biographies. I have read at least one book in a nonbiography category (otherwise, I would not be able to tell that I prefer biographies, which implies a comparison).
What is the difference? GMAT deductions are usually things that would cause us to say, “Duh!” in the real world.
“My favorite category of book is biography.”
“Oh, so you must not like fiction as much as you like biographies.”
“Uh… well, yeah, that’s what ‘favorite’ means. I don’t like anything else better.”
A GMAT deduction should feel like a “duh” deduction—something totally boring that must be true, given the information in the passage. Here, try out an Inference question.
That article also explains how to analyze your work and the problem itself. Did you miss something in the passage? Why? How can you pick it up next time? Did you fall for a trap answer? Which one? How did they set the trap and how can you avoid it next time? And so on.
Specific questions can come in one other (not as common) flavor: the Why question. These are sort of a cross between Specific Detail and Inference questions: you need to review some specific information in the passage, but the answer to the question is not literally right in the passage. You have to figure out the most reasonable explanation for why the author chose to include a particular piece of information.
Test out this Why question to see what I mean.
