Sample GMAT Critical Reasoning Questions with Detailed Explanations

Here are 3 practice GMAT Critical Reasoning questions, complete with detailed explanations to help you understand the reasoning process behind the correct answer.

Question 1: Strengthen the Argument

Argument:
"Many universities are now offering online degree programs, claiming that they provide flexibility and cost savings. Students report greater work-life balance and overall satisfaction with online programs."

Question:
Which of the following, if true, would most strengthen the argument?

A) Online programs typically cost 50% less than traditional in-person programs.
B) Research shows that online students work more hours per week than traditional students.
C) Students enrolled in online programs report higher levels of stress due to juggling work and school.
D) Studies indicate that the dropout rate in online programs is higher than that in traditional programs.
E) Employers view online degrees as just as credible as traditional degrees.

Correct Answer: A) Online programs typically cost 50% less than traditional in-person programs.

Explanation:
The argument states that online programs provide cost savings and flexibility. To strengthen this argument, we need an answer choice that reinforces those claims. Option A supports the cost savings argument directly, making it the best choice. The other options either introduce negative factors or are unrelated to the core claims of cost savings and flexibility.

Question 2: Weaken the Argument

Argument:
"A study showed that the implementation of a 4-day workweek resulted in a 10% increase in productivity at a company. Therefore, all companies should adopt a 4-day workweek."

Question:
Which of the following, if true, would most weaken the argument?

A) A similar study conducted in a different industry showed a decrease in productivity with a 4-day workweek.
B) Employees working a 4-day workweek reported higher job satisfaction.
C) A 4-day workweek has been shown to reduce burnout and stress among employees.
D) The study did not account for the effects of technological improvements on productivity.
E) The company that implemented the 4-day workweek has a unique culture that may not be replicable in other companies.

Correct Answer: A) A similar study conducted in a different industry showed a decrease in productivity with a 4-day workweek.

Explanation:
The argument generalizes that all companies should adopt a 4-day workweek based on one study. To weaken the argument, we need evidence that counters the claim. Option A provides an example from a different industry where the 4-day workweek resulted in a decrease in productivity, thus weakening the generalization that the 4-day workweek is beneficial for all companies.

Question 3: Assumption

Argument:
"Since a higher percentage of people are choosing electric cars, it’s clear that the future of transportation lies in electric vehicles. The growing popularity of electric cars will drive improvements in energy efficiency and reduce our reliance on fossil fuels."

Question:
Which of the following is an assumption of the argument?

A) Electric cars are more affordable than traditional gasoline-powered cars.
B) The future of transportation will involve technological advancements in electric vehicles.
C) People will continue to choose electric cars as their primary mode of transportation.
D) Electric cars will reduce energy consumption and greenhouse gas emissions.
E) There is a significant global demand for electric vehicles.

Correct Answer: C) People will continue to choose electric cars as their primary mode of transportation.

Explanation:
The argument claims that the future of transportation lies in electric cars, assuming that the growing popularity will continue into the future. Option C highlights this assumption — that people will continue to choose electric cars. Without this assumption, the argument would lack a foundation for predicting the future of transportation.

Question 4: Inference

Argument:
"A recent survey found that 60% of people who participate in regular exercise report better mental health compared to those who don't. Mental health professionals recommend exercise as part of a comprehensive mental health care plan."

Question:
Which of the following can be inferred from the argument?

A) Regular exercise is the only factor influencing mental health.
B) People who exercise regularly tend to be happier than those who do not.
C) Mental health professionals are likely to prescribe exercise as a treatment for mental health issues.
D) There is a significant number of people who do not participate in regular exercise.
E) Mental health improves only for people who engage in intense physical exercise.

Correct Answer: C) Mental health professionals are likely to prescribe exercise as a treatment for mental health issues.

Explanation:
The argument suggests that regular exercise is beneficial for mental health, and mental health professionals recommend it as part of a care plan. The inference that can be drawn is C, as it logically follows from the argument that mental health professionals are likely to incorporate exercise into treatment. The other choices either don't follow from the argument or introduce new, unsupported claims.

Question 5: Resolve the Paradox

Argument:
"The company introduced a flexible working hours policy, yet employee satisfaction surveys revealed a significant drop in job satisfaction. The company believed that offering more flexibility would improve work-life balance and morale."

Question:
Which of the following, if true, would best resolve the paradox?

A) Many employees prefer fixed working hours and dislike the ambiguity of flexible hours.
B) The company recently implemented a significant pay cut, which may have contributed to the dissatisfaction.
C) Employee turnover increased after the policy was introduced.
D) The flexible working hours policy was optional and employees were allowed to continue with their regular schedules.
E) A new manager was hired around the time the policy was introduced, and employees felt his leadership style was ineffective.

Correct Answer: A) Many employees prefer fixed working hours and dislike the ambiguity of flexible hours.

Explanation:
The paradox is that the company expected flexible working hours to increase job satisfaction, yet the surveys showed a drop. Option A helps resolve this paradox by explaining that many employees may not prefer flexibility and instead prefer the structure of fixed hours, which directly contradicts the company's assumption. The other options either don’t explain why satisfaction dropped or introduce unrelated factors.

Types of GMAT Critical Reasoning Questions You Will Face

GMAT Critical Reasoning presents several types of questions designed to assess different aspects of logical thinking. Each question type challenges your ability to evaluate, strengthen, weaken, or draw conclusions from arguments. Let’s explore the key types you’ll encounter:

1. Strengthen the Argument

In these questions, you'll be asked to select the answer choice that supports or reinforces the argument’s conclusion. Your task is to find evidence or reasoning that makes the argument’s conclusion more compelling.

Example:
Argument: "Many companies are switching to a four-day workweek, claiming it improves productivity and employee satisfaction."
Question: Which of the following, if true, would strengthen this argument?
Answer Choice: "Studies show that employees with a shorter workweek report higher job satisfaction and better mental health."

2. Weaken the Argument

These questions focus on finding the answer choice that undermines the argument. You’ll need to identify a statement that challenges or weakens the logic behind the conclusion.

Example:
Argument: "Implementing a longer workday will lead to higher productivity because employees will have more time to finish tasks."
Question: Which of the following, if true, would weaken this argument?
Answer Choice: "Research shows that longer workdays result in greater employee burnout and lower overall productivity."

3. Assumption

Assumption questions require you to identify the unstated belief that the argument relies on. Without this assumption, the argument would fall apart. Your job is to spot the necessary yet hidden premise.

Example:
Argument: "The company should invest in renewable energy because it will lead to long-term cost savings."
Question: Which of the following is an assumption made by the argument?
Answer Choice: "Renewable energy investments will result in substantial cost savings over time."

4. Inference

Inference questions ask you to deduce what must logically follow from the argument, even though it isn’t explicitly stated. These questions often test your ability to read between the lines and draw conclusions based on the provided information.

Example:
Argument: "The city has increased its budget for public parks and recreation facilities by 15% this year."
Question: Which of the following can be inferred from the argument?
Answer Choice: "The city is prioritizing public spaces and community well-being."

5. Evaluate the Argument

In these questions, you must select the answer choice that would help assess the strength or validity of the argument. This involves finding an option that either supports or questions the logic behind the argument.

Example:
Argument: "The new policy restricting internet usage in the workplace will improve employee focus."
Question: Which of the following would help evaluate the argument?
Answer Choice: "The policy could increase employee frustration, leading to decreased motivation and focus."

6. Boldface

Boldface questions highlight parts of the argument and ask you to determine the role these bolded sections play in the reasoning process. This can involve identifying whether the bolded text supports, contradicts, or provides an assumption for the argument.

Example:
Argument: "Some experts claim that increasing the minimum wage will reduce poverty. However, other experts argue that raising the minimum wage could lead to higher unemployment."
Question: What role does the boldfaced part play in the argument?
Answer Choice: "The boldfaced part presents an opposing viewpoint that weakens the argument."

7. Resolve the Paradox

These questions present a situation where two seemingly contradictory pieces of information are provided. Your job is to resolve the paradox by identifying the answer that reconciles the conflicting information.

Example:
Argument: "While the company's sales increased by 20% last quarter, employee turnover rates also surged during the same period."
Question: Which of the following resolves the paradox?
Answer Choice: "The company introduced a highly competitive sales incentive program, leading to both increased sales and dissatisfaction among employees."

8. Complete the Argument

In complete-the-argument questions, you are asked to complete the reasoning process by selecting the answer choice that logically follows or completes the argument.

Example:
Argument: "The new advertising campaign for the product has failed to generate the expected sales, despite its innovative approach. Therefore, the company should reconsider ________."
Question: Which of the following completes the argument?
Answer Choice: "The company's marketing strategy and target demographic."

Proven Strategies to Tackle GMAT Critical Reasoning Questions

GMAT Critical Reasoning questions can be challenging, but with the right approach, you can tackle them effectively. Here are some proven strategies to help you improve your performance on these questions and boost your confidence during the exam.

1. Understand the Question Type Before Answering

Each Critical Reasoning question type (Strengthen, Weaken, Assumption, etc.) requires a different approach. Always start by identifying the type of question before jumping to the options. This helps you focus on what’s being asked, rather than getting distracted by irrelevant details.

Tip: Carefully read the prompt and identify key phrases like “assume,” “strengthen,” or “weaken,” which will give you a clue about the required approach.

2. Break Down the Argument Step-by-Step

For any argument presented in a Critical Reasoning question, break it down logically. Identify the conclusion (the statement the author is trying to prove), and look for the evidence (the reasons provided to support the conclusion). This step will help you understand the underlying structure of the argument and make it easier to find flaws or strengthen it.

Tip: Draw a quick diagram or outline of the argument’s structure, marking the conclusion, evidence, and any assumptions.

3. Eliminate Clearly Wrong Answer Choices

After understanding the argument and question, immediately eliminate any answer choices that are obviously incorrect. Look for answers that:

• Introduce new information that wasn’t discussed in the argument.
• Present an extreme view that doesn’t align with the context of the argument.
• Are irrelevant to the question being asked.

Tip: Use the process of elimination to narrow down the choices. This increases your chances of selecting the correct answer.

4. Focus on the Logic of the Argument, Not External Knowledge

In GMAT Critical Reasoning questions, you should rely solely on the information provided in the argument. Don’t bring in outside knowledge or assumptions about the topic. The test evaluates your ability to reason through the information at hand, not your expertise in the subject.

Tip: Avoid overthinking or making assumptions beyond what is given in the question stem and the argument itself.

5. Practice Active Reading and Time Management

Critical Reasoning questions require careful reading and analysis. While reading the argument, highlight or underline key phrases that hint at the conclusion, evidence, or assumption. As you practice, focus on improving your speed without sacrificing accuracy.

Tip: Practice regularly under timed conditions to get used to the pace of the exam. This will help you manage your time more effectively on test day.

6. Look for Assumptions in the Argument

Many Critical Reasoning questions will test your ability to identify the underlying assumptions. These are unstated premises that the argument depends on to be valid. Recognizing the assumption will often guide you to the right answer.

Tip: Ask yourself, “What must be true for this argument to hold?” This mindset will help you pinpoint hidden assumptions.

7. Stay Calm and Don’t Rush

Critical Reasoning questions can be tricky, but staying calm and composed is key to performing well. Take a deep breath if you feel stuck, and remember that you don’t need to answer immediately. Sometimes taking a moment to reevaluate the argument and choices will lead to the correct answer.

Tip: Don’t spend too much time on one question. If you’re stuck, move on and come back to it later if necessary.
