If you've been treating all critical reasoning questions the same way, you're not alone. Most people start out doing exactly that. It seems reasonable — they're all short paragraphs with five answer choices, so the approach should be the same for each one.
That makes sense as a starting point. But the GMAT® has several different critical reasoning question types, and each one asks you to do something different with the argument in front of you. A strengthen question and an inference question aren't variations of the same task. They're different tasks that happen to share a format.
This guide covers the format, a repeatable process for every CR question, the seven question types and what each one asks you to do, and the strategies that matter most for improving your accuracy.
Where Critical Reasoning Lives on the GMAT® Focus Edition
On the GMAT® Focus Edition, critical reasoning is part of the Verbal section. Verbal has 23 questions in 45 minutes, and the section is computer-adaptive.
There are two question types in Verbal: critical reasoning and reading comprehension. The split is roughly half and half, though the exact number of each varies from test to test. You can expect somewhere around 10 to 13 critical reasoning questions.
Each critical reasoning question gives you one paragraph, one question, and five answer choices. One question per paragraph — unlike reading comprehension, where a single passage comes with multiple questions.
For a full breakdown of the Verbal section, see our GMAT® Verbal Score guide.
The Critical Reasoning Format
Every CR question has the same structure.
A short paragraph at the top of the screen. This is the argument. Sometimes it's a full argument with a conclusion and evidence. Sometimes it's just a set of facts with no conclusion.
A question below the paragraph. This tells you what to do with the argument.
Five answer choices below the question. One is correct. The other four are wrong, and the GMAT® writes them to be tempting.
The format is extremely consistent. What changes is what the question asks you to do with the argument. That's why the question type matters so much.
The Problem with Treating All CR Questions the Same Way
Here's an analogy. Volleyball and tennis are both sports played with a net. But if you try to apply tennis strategy to volleyball, the approach tends to break down. Some skills transfer — hand-eye coordination, quick reactions. But the rules are different, the strategies are different, and the things you need to do to win are different.
Critical reasoning question types work the same way. A strengthen question and a describe the role question share some underlying skills — you need to understand the argument in both cases. But what you do with that understanding is different. If you approach a strengthen question the way you'd approach an inference question, the answer choices that look right may not be right.
The first step to improving CR accuracy is learning the difference between each question type. The second step is practicing those differences until they're automatic — so automatic that when you see a strengthen question, you don't have to think about what to do. You just do it.
A Repeatable Process for Every CR Question
Before you worry about individual question types, you need a system for your first read. Here's the process we recommend.
Step 1: Read the question first
Don't read top to bottom. Start with the question below the paragraph. This tells you what type of question you're dealing with, which tells you what to look for in the argument.
Some people prefer to read the argument first. That can work too. But reading the question first helps you orient — you know whether you're looking for a conclusion, looking for an assumption, or looking for something else entirely before you start reading.
Step 2: Read the argument and find two things
Once you know the question type, read the paragraph. On your first read, you're looking for two things.
The first thing: what is the author's ultimate opinion? This is the main conclusion. Look for words like "should," "ought to," "therefore," "thus," or "so." These often signal that the author is making a recommendation or drawing a conclusion.
Sometimes there are multiple opinions in an argument. Someone else might state a view, and the author might agree or disagree. Your job is to find the author's ultimate opinion — the last link in the logical chain. That's the main conclusion.
The second thing: what evidence does the author use to support that conclusion? Evidence is anything that makes the conclusion more likely. It could be facts, data, or other opinions. The role of each piece of evidence only makes sense in relation to the conclusion, so finding the conclusion first matters.
Two question types — inference and explain — don't have conclusions in the argument. We'll cover those when we get to them. For the other five types, finding the conclusion and evidence is your foundation.
Step 3: Eliminate answer choices
Once you've identified the question type and broken down the argument, go to the answer choices.
On your first pass, don't overthink each option. Read all five. Eliminate anything that's clearly wrong. If an answer choice is long and confusing, skip it for now. Come back to it if you need to.
A common mistake is spending a lot of energy trying to deeply understand each answer choice on the first read. That costs time. A quick first pass lets you see the landscape. Then you can invest more energy in the remaining options.
The Seven Critical Reasoning Question Types
Now let's break down each question type and what it asks you to do. This is the part that needs to become automatic.
1. Describe the Role (Boldface) Questions
These are the easiest to spot because they're the only CR questions with boldface text in the argument. A typical question might ask, "The boldface portion plays which of the following roles in the argument?"
Not every describe the role question has boldface text, but most do. When you see one that does, it's a clear signal of the question type.
Your job is to identify what each boldface statement does. Is it a conclusion? Is it evidence? Is it something else?
If you've correctly identified the main conclusion and the evidence, you're most of the way to the right answer. The tricky part is the answer choices — they tend to have complex, technical wording. Practice these enough to recognize the patterns.
If you can't figure out what the conclusion is on a describe the role question, make a quick guess and move on. Without the conclusion, you don't have a foundation for the rest of the question.
2. Assumption Questions
An assumption is something that's not written down in the argument but has to be true for the conclusion to hold. If the assumption is false, the conclusion collapses.
When you see an assumption question, you're looking for an answer that meets two criteria. It's not stated in the argument. And it must be true — otherwise the conclusion falls apart.
Here's a quick example. Say the argument is: "Scientists in Nevada have discovered that the sky is actually red, not blue. As a result, we should encourage public school teachers to update their lesson plans."
The conclusion is the recommendation: we should update lesson plans. The evidence is the scientific discovery. But the author is assuming the discovery is accurate. That's not stated — we don't know anything about the methods, the peer review, or whether these scientists are reputable. If the data turns out to be wrong, the recommendation falls apart. That's the assumption.
3. Strengthen and Weaken Questions
These are the most common CR question types. You'll see more of these than any other type.
Both strengthen and weaken questions introduce new information. The answer choices will contain facts or claims that weren't in the original argument.
A strengthen question asks: which answer makes the conclusion more likely? A weaken question asks: which answer makes the conclusion less likely?
The way strengthen and weaken work is through the assumption. Think of the assumption as the glue holding the argument together. A strengthen answer adds more glue — it makes the assumption more likely to be true. A weaken answer dissolves some of that glue — it makes the assumption less likely to be true.
Going back to our example: if a strengthen answer said "the scientists' data has been peer-reviewed and fact-checked by reputable sources," that supports the assumption that the discovery is accurate. The conclusion gets stronger.
If a weaken answer said "the data has not been fact-checked and the scientists are not affiliated with any university," that undermines the assumption. The conclusion gets weaker.
One quick tip: questions that ask you to fill in a blank in the argument are often strengthen questions. If the blank is at the end and the question says the completed argument would be strongest, that's a strengthen question in disguise.
4. Evaluate the Argument Questions
These questions ask you what information would help you determine whether the conclusion is sound. The answer choices often come in the form of questions themselves.
Your job is to find an answer where one response would strengthen the conclusion and the opposite response would weaken it. If the answer to "Has the data been fact-checked?" is "yes, by reputable sources," that strengthens. If the answer is "no, it hasn't been," that weakens. That contrast is what makes it the right answer to an evaluate question.
Evaluate questions tend to be the most time-intensive CR type because they're essentially a strengthen and weaken question combined. If you're running short on time and need to make a strategic guess somewhere, evaluate questions can be good candidates.
5. Inference (Provide a Conclusion) Questions
These are tricky because the word "inference" means something different on the GMAT® than it does in everyday life.
In regular conversation, an inference is something that's probably true. If someone says their car is dirty, you'd infer they haven't washed it recently. That's a reasonable guess.
On the GMAT®, an inference has to be 100% provable based on the information in the argument. Not likely. Not probably. Provably true.
If the argument says "my car is dirty," the only valid inference is "my car is not clean." That's the definition of dirty — it's provably true. You can't infer that the person hasn't washed the car recently. Maybe they washed it five minutes ago and a truck splashed mud on it. You don't know.
Inference questions are one of two types that don't have a conclusion in the argument. The entire paragraph is evidence, and you're pulling a provable fact from it.
The same logic applies to "provide a conclusion" questions. Despite the word "conclusion," these are the same as inference questions. You're looking for something 100% provable from the given information, not the author's opinion.
6. Explain (Resolve) Questions
These questions present a situation that seems contradictory, and you need to find the answer that explains why the contradiction isn't actually a contradiction.
For example: "Even though gasoline prices have quadrupled this year, XYZ Trucking Company's profits are higher than ever." That seems strange — if a trucking company's fuel costs go up dramatically, profits should go down, not up.
The right answer might be that all of XYZ's competitors recently went out of business. Now XYZ has a monopoly, so even though costs went up, revenue went up even more. The tension is resolved.
Explain questions are the second type that don't have a conclusion in the argument. The paragraph is all evidence, and you're looking for an explanation that makes the evidence make sense.
7. Flaw, Omission, and Analogy Questions
These are rare. You may take the GMAT® several times and never see one. If you do see one, it'll likely be just a single question.
Flaw questions ask you to identify what's wrong with the argument's reasoning. Omission questions ask what the argument fails to consider. Analogy questions ask whether a comparison between two situations is valid.
Because these are so uncommon, we recommend checking your GMAT®-specific study materials for how to approach them rather than investing a lot of prep time here. If you're targeting a very high score — 705 or above — it's worth having a strategy. For most test takers, the six types above are where your prep time should go.
How to Study Critical Reasoning
If you could only do one thing to improve CR accuracy, it would be this: practice identifying conclusions and evidence reliably and quickly.
By test day, you should be able to read a CR argument and identify the main conclusion and supporting evidence in under 90 seconds. If it takes longer, that's okay at first — start with accuracy, then build speed.
One way to practice this: take 20 to 50 arguments from the Official Guide and don't answer the questions. Just read each argument and identify the conclusion and evidence. Check yourself against the answer explanations. This builds the foundational skill that every CR question type depends on.
The second thing: memorize what each question type asks you to do. Make flashcards. Study them every day. When you can look at a strengthen question and instantly know your approach without having to think about it, you're where you need to be.
If you're using a general logic textbook for CR prep, consider switching to a GMAT®-specific source. The GMAT® has its own version of logic, and a general logic book may not cover the nuances you need. The Manhattan Prep Critical Reasoning study guide is one reputable option. The Official Guide is essential for practice questions.

FAQ
How many critical reasoning questions are on the GMAT® Focus Edition?
The Verbal section has 23 questions in 45 minutes. You'll see roughly 10 to 13 critical reasoning questions, with the rest being reading comprehension. The exact split varies from test to test.
What's the most common CR question type?
Strengthen and weaken questions appear more often than any other CR type. You may see as many as three of these on a single test. Knowing how to approach strengthen and weaken questions well gives you the biggest return on study time.
Should I read the question or the argument first?
We recommend reading the question first. It tells you what type of question you're dealing with, which helps you know what to look for in the argument. Some people prefer to read the argument first and that can work too. The important thing is to have a consistent system.
What's the difference between an inference and a conclusion on the GMAT®?
In everyday language, they mean similar things. On the GMAT®, a conclusion is the author's opinion — it's stated in the argument. An inference is something that must be 100% provable from the information given — it's not stated, and it's not a guess. "Provide a conclusion" questions are actually inference questions, not conclusion questions.
Do I need to study formal logic for GMAT® critical reasoning?
Probably not. The GMAT® tests its own version of logic, which differs from the formal logic you'd study in a philosophy course. A GMAT®-specific prep source will cover what you need. A general logic textbook might not help and could even cause confusion.
How long should I spend on a critical reasoning question?
It depends on the question type and your overall timing strategy. Evaluate questions tend to take the longest because they combine strengthen and weaken logic. Strengthen and weaken questions usually take less time once you've mastered the approach. For a full pacing system, see our GMAT® Timing Strategy guide.
What if I can't find the conclusion in a CR argument?
If you can't identify the conclusion after two reads, make a quick guess and move on. The conclusion is the foundation for almost everything in CR — without it, you're guessing on the answer choices too. Spending extra time on a question where you're stuck usually doesn't help. See our guide on when to let go of a GMAT® question for more on this.
