    Understand the range of CR Question types you might see on the GMAT

    Learn to identify the type of question based on how the question stem is worded

    Increase speed and efficiency by quickly identifying the question type and the corresponding framework strategy associated with that question type


GMAT Pill Analyzed Critical Reasoning Question Types in The Official Guide (OG13)…


Of the 124 available CR questions from the Official Guide 13th edition (excluding questions from the diagnostic section), GMAT Pill has identified 79 of the 124 questions (52%) that test you on how to strengthen an argument.

At GMAT Pill, we noticed that “strengthens” questions tested the same types of logic over and over and that they all fall under a core set of five frameworks. That means, if you learn the relevant 5 frameworks for “strengthens” questions, you’ll have learned the strategies to answer more than half of the CR questions on the GMAT.

We also noticed that “strengthens” questions tended to be worded in a similar way. The question stems tended to repeat so we categorized “strengthens” questions into 3 subcategories:
    General Strengthens (30%)
    Helps Explain (12%)
    Assumption / Argument Depends (10%)

The “helps explain” question stem is typically worded as: “Which of the following most helps explain the discrepancy observed above?”

The “assumption / argument depends” question stem is typically worded as: “Which of the following is an assumption on which the argument depends?”

These two question stems are variations off of a “strengthens” question and come up quite frequently in the OG13. As a result, we created separate categories for them. All other “strengthens” questions fall under the “general strengthens” category.

These are the official guide questions with the “general strengthens” concept in action.

#1, 5, 7, 11, 12, 14, 17 19, 23, 30, 31, 33, 35, 40, 45, 50, 52, 53, 55, 56, 59, 64, 65, 67, 69, 74, 80, 81, 95, 101, 102, 103, 108, 111, 118, 120, 121

You’ll find a more detailed listing of the relevant OG13 questions by GMAT Pill CR Question Type in the table further below.


Overall Breakdown of OG13 CR Question Types


Here is a more complete breakdown of the GMAT Pill categorizations for the CR Questions in the OG13.
    Strengthens (52%)
      General Strengthens (30%)
      Helps Explain (12%)
      Assumption / Argument Depends (10%)
    Weaken (20%)
    Evaluate (10%)
    Boldface (10%)
    Inference (8%)

“…develops the argument by…”

On your GMAT, you’ll only see around 14 or so CR questions out of the 41 verbal questions. As such, it’s possible you might not get a question in each of the categories defined above. You may do a practice test at home, then take the real GMAT and suddenly discover that the questions were not familiar to you. You may have gotten a question type that you didn’t see in your practice test.

So it’s no guarantee that you’ll see all 7 CR question types on the GMAT exam that YOU take. But you should definitely be prepared to tackle all of these types of CR questions by test day.


GMAT Pill CR Frameworks


GMAT Pill utilizes a core set of 10 frameworks to approach the CR question types.

At the core is the 52% of CR questions covered by Frameworks #1-5. These are the “strengthens” questions. Here again, are the the "Strengthens" questions that represent 52% fo CR questions:
    Strengthens (52%)
      General Strengthens (30%)
      Helps Explain (12%)
      Assumption / Argument Depends (10%)

And here are the GMATPill Framework Strategies to attack these "Strengthens" questions:

Strategy for "Strengthens": General Visualization
Strategy for "Strengthens": Framework #1: Before/After
Strategy for "Strengthens": Framework #2: Linked Chains
Strategy for "Strengthens": Framework #3: Expectation vs Actuality
Strategy for "Strengthens": Framework #4: Negation (Regular and Exclusive)
Strategy for "Strengthens": Framework #5: Sample Generalization

Note here that there are 3 subcategories to “strengthens” questions.
    General Strengthens: Utilizes any of Frameworks #1-5 + General Visualization
    Helps Explain: Utilizes Framework #3
    Assumption / Argument Depends: Utilizes Frameworks #1, 2, 4, 5 + General Visualization

The remaining 48% of CR questions are covered by Frameworks #6-10

Framework #6: Weakens and Defends
Framework #7: Evaluate
Framework #8: Inference
Framework #9: Bold-faced
Framework #10: Circular Reasoning

The corresponding framework for the remaining CR question types are more simple to remember. “Weakens” questions use the “weakens” framework; “evaluate” questions use the “evaluate” framework; “inference” use the “inference” framework; and “bold-faced” questions use the “bold-faced” framework. The last one, Framework #10 Circular Reasoning, is more of a miscellaneous framework which actually is a form of “strengthens” but is very rare to see on the GMAT.

While we won’t go into detail about these 10 Core CR Frameworks, it’s good to see that there is some organization and structure towards the approach to CR questions. That’s key. When you prepare, it’s more important to understand the general concepts of what is being tested, rather than the specifics of a question. Otherwise, if you simply modify the question a little bit (something the GMAT folks do), you’ll be stumped. Something you answered correctly before suddenly becomes foreign to you and you get it wrong. You want to avoid that by focusing your studies on the core logic that is being tested. Master the core and you’ll be on your way to mastering the GMAT.

Hi,

Can you explain whether the question stem “…an assumption that supports drawing the conclusion above” would fall in Assumption or General Strengthener category?

In OG 13, question 21 has the above question stem and ideally it should fall in Assumption question category.

Please explain.

Hey Argha,

This sort should be filed under assumption

I agree - they make it tricky by including the phrase 'supports the conclusion', but essentially what Q21 is doing is looking for something that is assumed in the conclusion.

I.e. Something without which the conclusion would fail.

If it is like that, then must be assumption.

Make sense?

James
