GMAT Critical Reasoning: Questions, Strategies & Tips

Critical Reasoning questions rarely feel difficult because you cannot understand the argument. They feel difficult when two answer choices both seem to fit, and you have to decide which one actually answers the question.

The trap is treating “relevant” as “correct.” An answer can relate to the argument and still fail the question. To avoid that, you need to identify what the argument is trying to establish, what the question is asking you to do, and what the correct answer needs to accomplish.

This guide covers the major GMAT Critical Reasoning question types, how to approach them, and the traps that make the wrong answers so tempting.

What Is GMAT Critical Reasoning?

Critical Reasoning (CR) is one of the two question formats in the GMAT Verbal Reasoning section, alongside Reading Comprehension. The official GMAT exam content overview lists 23 Verbal questions to be completed in 45 minutes.

In CR, you read a short argument and then answer a question about it. The question might ask you to find an assumption, identify a flaw, or determine what would strengthen or weaken the argument.

Consider an argument that says employees who work from home are more productive because they complete more tasks each week than office-based employees. To strengthen that argument, you might need to know whether the two groups were given the same workload or whether the remote employees simply had more tasks to complete. That’s the kind of thinking CR requires. You need to look at what the argument claims, then examine whether the evidence actually supports it.

CR questions are based on a short reading passage, usually fewer than 100 words. And because CR tests your reasoning, not your knowledge of the subject, you don't need to be an expert in whatever topic appears on the screen.

The Basic Anatomy of an Argument

A CR argument usually has a few moving parts, but three matter most: the evidence, the conclusion, and the assumption connecting them.

Consider this argument:

Sales increased after the company introduced a new app. Therefore, the app caused the increase in sales.

At first glance, the conclusion seems to follow from the evidence. But look more closely. The evidence only tells us that the sales increase happened after the app launched. It doesn't establish that the app caused it.

And that's the gap to look for. Maybe the company also lowered its prices. Maybe a competitor left the market. Maybe sales normally increase during that month.

The evidence gives you one fact. The conclusion takes that fact a step further. The assumption is what allows the author to make that leap.

Once you start looking for that gap, many CR questions become easier to unpack. A strengthen question might give you information that closes the gap. A weaken question might expose another explanation. An assumption question asks you to identify what the argument needs to hold together.

How to Approach GMAT Critical Reasoning Questions

Use the same six-step process whenever possible:

Question stem → Argument → Conclusion → Logical gap → Prediction → Elimination

The details change depending on the question type, but this framework gives you a consistent way to approach CR instead of figuring out what to do from scratch every time.

1. Read the question stem first

Before you dig into the argument, figure out what you’re being asked to do. The question stem tells you what to look for as you read.

You might be asked to:

• Strengthen the argument
• Weaken the argument
• Identify an assumption
• Draw an inference
• Explain a surprising result
• Identify the role a statement plays in the argument

This small step can change how you read the entire passage. If you're answering a strengthen question, you're looking for information that makes the conclusion more convincing. If you're answering an inference question, you're looking for something that must follow from the information given.

For example:

Which of the following most supports the argument above?

Which of the following is most strongly supported by the statements above?

The wording is similar, but the questions are asking you to do different things. The first asks you to strengthen an existing argument. The second asks you to conclude from the information provided.

So don't start by trying to solve the argument. Start by identifying the job. Once you know what the question wants, you can read the argument with that job in mind.

2. Separate the evidence from the claim

Once you know what the question is asking, figure out what the passage actually gives you.

As you read, ask:

• What information is presented as a fact?
• Which statement is being used to support another?
• What does the author want me to believe?
• Am I looking at an argument, or simply a set of facts from which I need to conclude?

For example:

A retailer noticed that online sales increased by 20% after it redesigned its website. The retailer concludes that the redesign caused the increase.

The 20% increase is evidence. The claim that the redesign caused it is the conclusion. Keeping those two separate makes the next step much easier because you can start asking what connects them.

Also, don't get distracted by whether the scenario sounds realistic. If the GMAT gives you a statement as fact, take it as given and evaluate how the argument uses it. Your job is to test the reasoning, not fact-check the scenario.

3. Find the conclusion

Ask yourself, what does the author want me to believe?

That statement is the conclusion. The other parts of the argument provide the evidence or reasoning used to support it.

For example:

Stores that stayed open later earned more revenue. Therefore, extending store hours will increase profits.

The conclusion is that extending store hours will increase profits. The higher revenue is evidence used to support it.

Words such as therefore, thus, hence, and consequently can help you spot the conclusion, but don't rely on them. Sometimes the conclusion appears without a clear signal word.

4. Find the logical gap

Now ask, what has to be true for that conclusion to follow?

In the example above, higher revenue does not automatically mean higher profit. Keeping stores open longer could also increase staffing, utilities, and other operating costs.

So the argument assumes that the additional revenue will outweigh the additional costs.

That assumption is the logical gap. It is the part of the argument that the evidence does not fully establish.

5. Predict what the answer needs to do

Before looking at the choices, use that gap to predict what would matter.

For the store-hours argument, information showing that the extra revenue is greater than the added costs would strengthen the conclusion. Evidence that the added costs are higher than the extra revenue would weaken it.

You don't need to predict the exact answer. Just know what kind of information would affect the argument before the choices try to distract you.

6. Eliminate answers that miss the point

Now bring that same gap to the answer choices.

Suppose you're asked to weaken the argument that longer store hours will increase profit. An answer saying customers prefer shopping in the evening may sound relevant, but it doesn't weaken the link between longer hours and higher profit. An answer showing that extra staffing costs exceed the additional revenue does.

Cross out answers that don't change the conclusion in the direction the question asks for.

GMAT Critical Reasoning Question Types

Broadly, the GMAT Verbal section has three types of Critical Reasoning questions:

1. Attack or improve an argument or plan. These questions ask you to find an answer that exposes a flaw, strengthens the reasoning, or addresses a weakness in the argument.
2. Analyze the reasoning. These questions ask you to identify or describe how the argument is constructed. They are commonly called Method of Reasoning questions.
3. Draw a valid conclusion. These questions ask you to determine what logically follows from the information in the passage. They are commonly called Inference or Conclusion questions.

The first category includes several common subtypes: Strengthen, Weaken, Assumption, Evaluate, and Explain the Paradox. According to a July 2026 mba.com Featured Contributor article, more than 75% of GMAT Critical Reasoning questions fall into this category. That's why we'll spend most of this section on how to solve these questions.

Argument-Based Questions

These questions revolve around the relationship between evidence and a conclusion. The question stem tells you how you need to test that relationship.

Strengthen Questions

A strengthen question asks which answer makes the argument more convincing.

Typical stems:

• Which of the following, if true, most strengthens the argument?
• Which statement provides the strongest support for the conclusion?
• Which fact most supports the proposed plan?

For example:

Last year, a restaurant began allowing customers to place orders through a mobile app. During the following six months, the restaurant's average monthly revenue was 15 percent higher than during the preceding six months. The restaurant's owner concludes that the mobile app increased the restaurant's revenue.

Which of the following, if true, most strengthens the argument?

An answer showing that the restaurant made no other significant changes during the six-month periods would strengthen the argument. It makes the mobile app a more plausible explanation for the increase in revenue.

A common trap is an answer that sounds positive but does not actually make the conclusion more convincing.

Weaken Questions

A weaken question asks which answer makes the conclusion less convincing.

Typical stems:

• Which of the following, if true, most weakens the argument?
• Which of the following would most undermine the conclusion?
• Which fact most calls the argument into question?

Consider:

A company found that employees who worked remotely completed an average of 12 percent more projects each quarter than employees who worked primarily in the office. The company therefore plans to allow all employees to work remotely, expecting company-wide productivity to increase.

Which of the following, if true, most weakens the argument?

Suppose the employees who worked remotely were chosen from among those who had already received the highest productivity ratings.

That gives us another explanation for the result. The employees may have been more productive before they began working remotely, so the evidence does not show that remote work caused the higher productivity.

Assumption Questions

An assumption is something that must be true for the argument's reasoning to work.

One useful check is the negation test: imagine the potential assumption is false. If the argument falls apart, you may have found a necessary assumption.

For example:

A city council plans to reduce traffic in the downtown area by increasing the cost of parking. The council argues that the higher parking fees will encourage commuters to use public transportation instead of driving.

The argument assumes which of the following?

The argument depends on enough affected commuters having a practical alternative to driving, such as reliable public transportation.

Negate that assumption:

Most commuters affected by the higher parking fees have no practical alternative to driving.

If that were true, the higher fees could make driving more expensive without causing many commuters to switch. The argument loses an important link.

Evaluate Questions

Evaluate questions ask which information would be most useful for deciding whether an argument or plan holds up.

The important part is that the information should matter either way.

For example:

A retailer plans to eliminate free returns on online purchases. Management estimates that the policy will increase annual profits because the company will spend less on return shipping. However, some executives worry that the policy will cause customers to shop elsewhere.

Which of the following would be most useful in evaluating the plan?

A useful question would be:

Would the number of customers lost because of the new return policy result in more lost profit than the company would save on return shipping?

If enough customers leave, the plan looks less promising. If few customers leave, the shipping savings could support the plan.

That two-direction effect is what makes the information useful for evaluating the argument.

Explain-the-Discrepancy or Paradox Questions

These questions give you two facts that seem inconsistent and ask you to explain how both can be true.

For example:

A manufacturer reduced the price of one of its products by 20 percent. Despite the lower price, the company's total revenue from the product increased during the following quarter.

Which of the following, if true, best explains the apparent discrepancy?

One possible explanation is that the number of units sold increased by substantially more than 20 percent. The company earned less per unit, but sold enough additional units to increase its total revenue.

The correct answer should provide the missing information that allows both facts to be true.

Reasoning and Structure Questions

These questions ask you to describe how an argument works rather than change its strength.

Method of Reasoning Questions

Method of Reasoning questions ask you to identify how the author builds the argument. The author might reject one explanation and propose another, use an example to support a broader claim, compare two situations, or point out a flaw in someone else's reasoning.

For example:

Which of the following best describes the method of reasoning used in the argument?

Before looking at the choices, put the argument into simple terms. You might reduce a complicated passage to “The author rejects explanation A and argues that explanation B is more likely.” Then look for the answer choice that describes that same structure.

The GMAT can express a straightforward reasoning pattern in formal language, so focusing on what the author actually does can make the choices easier to compare.

Boldface Questions

Boldface questions are a common form of Method of Reasoning question. They highlight two statements in the argument and ask you to identify the role each one plays.

For each bolded statement, ask what it is doing:

• Is it a premise supporting the conclusion?
• Is it the main conclusion?
• Is it an intermediate conclusion?
• Is it someone else's position?
• Is it evidence that the author later challenges?

Then match those roles to the answer choices. The challenge is often distinguishing between two statements that both sound important but play different roles in the argument.

Inference and Conclusion Questions

Inference questions ask how far you can go with the information in the passage. The right answer has to follow from what you're given, without quietly adding a new fact or making the claim broader than the evidence supports.

Consider this example

All analysts on Team X have completed financial-modeling training. Some employees who completed financial-modeling training also completed data-visualization training.

Which of the following can be inferred from the statements above?

Look at the wording carefully. Every Team X analyst completed financial-modeling training. Separately, some employees with that training completed data-visualization training.

That does not tell us that any of those employees are analysts on Team X. They could be, but the passage doesn't establish that.

So if an answer says that some Team X analysts completed data-visualization training, it's making a connection the passage never made.

That's the trap to watch for. An answer can sound perfectly reasonable and still go beyond the evidence. Pay attention when a choice changes some to all, applies a statement to a larger group, or turns something that may be true into something that must be true.

When two answers seem plausible, compare them against the exact wording of the passage. Which one can you support directly from the information given?

GMAT Critical Reasoning Strategies That Actually Help

1. When Two Answers Both Look Right, Compare Their Jobs

If you are stuck between two choices, do not reread the entire passage from scratch. Look at the difference between the two answers and ask what each one actually does to the argument. One might strengthen the conclusion directly, while the other is simply related to the topic. One might explain the result, while the other only shows that the result is possible. The correct choice is the one that performs the specific task the question asks for.

2. Use the Negation Test for Assumption Questions

For an assumption question, take an answer choice and negate it. If the argument falls apart when that statement is reversed, the answer is likely a necessary assumption. For example, if an argument depends on commuters having an alternative to driving, negate that idea and ask whether the conclusion still works if commuters have no practical alternative. This test is especially useful when several choices seem like reasonable assumptions.

3. Simplify Dense or Abstract Wording

A CR argument can feel harder than it really is when the wording gets complicated. Strip the argument down to its basic relationship before evaluating the choices. “The company introduced X, results changed, so X caused the change” is easier to work with than a paragraph full of business terminology. You are not changing the argument. You are removing the wording that makes the logic harder to see.

4. Review Why Your Wrong Answer Was Tempting

When you miss a CR question, knowing the correct answer is only part of the review. Figure out why your choice looked attractive in the first place. Did it address the topic but not the conclusion? Did you overlook one word that changed its meaning? Did you choose an answer that was possible when the question required something more certain? Naming the specific mistake gives you something concrete to recognize the next time it appears.

5. Practice in Two Stages

Focused practice helps you learn how each question type works, but mixed practice tests whether you can recognize the task without being told. Start by working through groups of the same question type so you can learn the reasoning pattern. Then mix strengthen, weaken, assumption, inference, and other question types together. That second stage is important because the test does not tell you which reasoning approach to use before you start.

GMAT Critical Reasoning Practice Questions

The best way to practice Critical Reasoning is to work through arguments where several answer choices seem plausible at first. The questions below use common GMAT CR patterns and focus on the reasoning that separates the correct answer from attractive distractors.

Practice Question 1: Weaken

A regional grocery chain introduced self-checkout stations in 12 of its stores. During the six months following the introduction, the average number of transactions processed per hour at those stores increased by 14 percent. The chain's management therefore plans to install self-checkout stations in all of its stores, reasoning that doing so will increase the number of transactions processed per hour throughout the chain.

Which of the following, if true, most seriously weakens the argument?

A. The stores selected for the self-checkout trial had previously processed fewer transactions per hour than the chain's other stores.

B. During the six-month trial, the 12 stores increased their advertising expenditures substantially, whereas most of the chain's other stores did not.

C. Customers who use self-checkout stations tend to purchase fewer items per transaction than customers who use staffed checkout lanes.

D. Some of the chain's stores that do not have self-checkout stations have recently experienced increases in the number of transactions processed per hour.

E. The chain expects the cost of installing self-checkout stations to vary considerably among its stores.

Answer: B

Why: The argument assumes that the increase in transactions was caused by the self-checkout stations. Choice B provides another change that could have caused the increase, making it less certain that the machines produced the result. Choice A describes a difference between the trial stores and other stores but does not explain the increase during the trial. Choice D shows that transaction rates can increase without self-checkout, but it does not establish that advertising caused the increase in the 12 trial stores.

Practice Question 2: Assumption

A manufacturer currently requires its sales representatives to attend quarterly in-person training sessions. The company is considering replacing those sessions with an online training program that representatives can complete independently. Management predicts that the change will reduce the company's training costs because it will eliminate the expense of conducting four in-person sessions each year.

The prediction above depends on which of the following assumptions?

A. Sales representatives will complete the online training program at approximately the same frequency as they currently attend in-person training sessions.

B. The cost of developing and maintaining the online training program will be less than the costs that the company will save by eliminating the in-person sessions.

C. Most sales representatives prefer completing training independently rather than attending in-person sessions.

D. The company will continue to require sales representatives to complete training each quarter.

E. The online training program will contain at least as much information as the current in-person sessions.

Answer: B

Why: The conclusion concerns lower total training costs, so the savings from eliminating the in-person sessions must exceed the costs of creating and maintaining the online program. If the online program costs as much as or more than the savings, the predicted reduction in costs would not follow. The other choices may affect how useful or practical the program is, but they are not necessary for the cost-reduction conclusion.

Practice Question 3: Explain the Discrepancy

Last year, a company's sales of Product X increased substantially after the company reduced the product's price by 10 percent. This year, the company again reduced the price of Product X by 10 percent, but sales increased only slightly. The company's marketing director concludes that the second price reduction was much less effective than the first.

Which of the following, if true, most helps to explain the difference between the two years?

A. The company's competitors reduced the prices of similar products by substantially more this year than they did last year.

B. The company's advertising campaign for Product X reached more potential customers this year than it did last year.

C. The profit margin on Product X was higher last year than it is this year.

D. The company introduced several other products this year that were marketed to the same customers as Product X.

E. The price of Product X was reduced by 10 percent at approximately the same time each year.

Answer: A

Why: The two facts that need to be explained are that the same size price reduction produced a much larger increase in sales in the first year than in the second. Choice A provides a reason the second reduction could have had less effect. If competing products became substantially cheaper this year, customers may have had less reason to switch to Product X despite its lower price. Choice B makes the difference harder to explain because greater advertising exposure would tend to increase sales.

Practice Question 4: Inference

A manufacturer operates exactly three production facilities: North, South, and West. Each facility produces at least one of the company's products. All products manufactured at North are inspected before being shipped. No product that is inspected before being shipped is shipped directly to a customer.

If the statements above are true, which of the following must also be true?

A. Some products manufactured at South are shipped directly to customers.

B. No products manufactured at North are shipped directly to customers.

C. All products manufactured at South are inspected before being shipped.

D. Some products manufactured at West are shipped directly to customers.

E. No products manufactured at West are inspected before being shipped.

Answer: B

Why: Every product manufactured at North is inspected before being shipped, and no inspected product is shipped directly to a customer. Therefore, no product manufactured at North can be shipped directly to a customer. The statements do not establish how products from South or West are inspected or shipped, so the other choices go beyond the information given.

The Bottom Line

CR gets easier when you stop treating each question like a new puzzle. The short passage may change, but the same skills keep coming up: argument analysis, logical reasoning, and the ability to separate a useful answer from an attractive incorrect choice.

As you practice, pay attention to the mistakes that keep repeating. If you miss because you overlook a single word, misread the given conclusion, or choose an answer that sounds relevant but does not affect the argument, you have found something specific to work on. That kind of pattern recognition can make approaching CR questions faster and help you eliminate answer choices with more confidence.

FAQs

How many Critical Reasoning questions are on the GMAT?

• The GMAT does not publish a fixed number of Critical Reasoning questions for each exam. The 23-question Verbal Reasoning section includes both Critical Reasoning and Reading Comprehension, so the exact mix can vary.

How much time should you spend on a GMAT Critical Reasoning question?

• The Verbal Reasoning section gives you 45 minutes for 23 questions, which works out to about 1 minute and 57 seconds per question on average. That is not a required time limit for CR. Some questions take longer than others, so focus on keeping a steady pace across the section.

Why do I keep getting GMAT Critical Reasoning questions wrong?

• A common problem is choosing an answer that sounds relevant but does not actually do what the question asks. You may also be missing a key word, misidentifying the conclusion, or accepting an answer that is possible without being strong enough to support the argument. When reviewing mistakes, focus on why your choice was tempting and what made the correct answer better.

How can I improve my GMAT Critical Reasoning accuracy?

• Start by practicing one question type at a time so you can recognize what each task requires. Then move to mixed sets and practice identifying the question type, conclusion, logical gap, and likely answer before looking closely at the choices. After each mistake, review the reasoning behind your wrong choice instead of simply checking the correct answer.
