The GMAT Critical Reasoning questions are designed to measure the reasoning skills that you use when you craft arguments, evaluate arguments, and formulate plans of action. It is a challenging section of the test, and you will definitely benefit by working through practice questions. Our free GMAT Critical Reasoning practice test is a great place to start your test prep.
Directions: Each of these GMAT critical reasoning practice questions are based on a short argument, a set of statements, or a plan of action. For each practice question, select the best answer of the choices given.
- Which of the following, if true, most strengthens this argument?
Habitat destruction presents a greater threat to wild game populations than does hunting.
Game meat is lower in unhealthy hormones and antibiotics than meat from commercially raised animals.
Purchased game meat is the primary source of animal protein for a significant number of people.
The wild animal population has held fairly steady over the past decade.
Drafting appropriate legislation would be a lengthy and expensive process.
- The adoption of this plan would be most likely to decrease employees' productivity if the employees' job functions required them to __________.
work undisturbed for several hours at a time.
submit their work for weekly managerial appraisal.
work late hours.
collaborate on monthly group projects.
correspond with banks daily, which are usually closed on Sundays.
- Any of the following statements, if introduced as an additional premise, makes the above argument logically correct EXCEPT:
Camembert cheese has less fat than Gouda cheese.
Gouda cheese is higher in fat than Brie cheese.
Gouda cheese and Brie cheese have the same fat content.
The fat content of Cheddar cheese is equal to the fat content of Brie.
Brie cheese is higher in saturated fat than cheddar cheese.
- Which of the following best suggests that the conclusion suggested by the composer is justified?
There are diary entries and correspondence that have survived to present-day which indicate Nannerl was as prolific as her brother.
Most of Mozart’s musical ability was inherited from his parents who were themselves talented musicians.
The composer’s opinion is shared by most experts on the Mozart family.
Women were not encouraged in Mozart’s day to become professional musicians.
Mozart’s earliest contributions were on the violin, while Nannerl’s were likely to be on the keyboard.
Answer choice B is not correct. Just because Wolfgang inherited musical abilities from his parents does not mean that his sister would have inherited the same abilities. Nannerl could have inherited traits (that were suppressed in her parents) from her grandparents who were not as talented as her parents.
- The conclusion of this argument assumes which of the following?
Better academic performance can be attributed to factors other than musical ability.
The skills required to learn to play the violin are common to all musical instruments.
High academic prowess results from the skills nurtured by learning to play an instrument.
There is no proven correlation between musical skill and academic ability.
Many high-ranked schools require students to learn to play an instrument at this age.
- In the given argument, what role do the boldfaced selections play?
The first is the argument's main conclusion; the second suggests an exception to that conclusion.
The first is evidence in support of the argument's main conclusion; the second is evidence in support of an alternative, rejected conclusion.
The first is an interpretation of evidence offered in support of the main conclusion; the second is other evidence offered in support of the main conclusion.
The first is an interpretation of evidence that would support an alternate conclusion; the second is evidence in support of the argument's main conclusion.
They are both evidence offered in support of a conclusion that is rejected.
- Which of the following could cause the assurances given by Eatco executives to the sales staff to be untrue?
A competing restaurant equipment supply firm also switches its salespeople over to a commission structure.
Some customers requesting items that are out of stock and have to be ordered.
The old salary structure did not include health insurance, but the commission structure provides the salespeople with the option to subscribe to a cafeteria-style insurance plan.
Several new restaurants are opening in the area.
The Eatco executives decided to hire several new salespeople on the commission structure, in order to make sure that all customers are getting the best possible service.
- Which of the following, if true, most strongly supports the psychologists’ interpretation of the link between punishment and antisocial behavior?
The rate of adults diagnosed as sociopaths who were not juvenile delinquents is four times lower than the rate of adults diagnosed as sociopaths who were juvenile delinquents.
The correlation found by the psychologists has been noted to be true for psychopaths and those with borderline personality disorder.
Almost everyone who spent time in juvenile hall as a youth exhibits abnormal behavior as an adult.
The likelihood of a juvenile delinquent becoming a diagnosed sociopath later in life increases the longer he or she remains incarcerated.
Less than half of adults who are diagnosed sociopaths have reported they spent less than one year in juvenile delinquent facilities in their youth.
One way to strengthen an argument is to show that the premises on which the argument is based are indeed valid. Answer choice (D) does this by suggesting that the length of time a juvenile spends in prison is related to the likelihood of a juvenile delinquent becoming a diagnosed sociopath later in life.
If you chose (A): This choice provides statistics that suggest that among adults diagnosed as sociopaths, those who were juvenile delinquents far outnumber those who were not juvenile delinquents. This answer choice merely confirms what the psychologists already stated. It does not support the causal relationship that the author suggests exists between juvenile delinquency/punishment and antisocial behavior later in life.
If you chose (B), remember that the mere existence of a similar correlation does not strengthen the original correlation.
If you chose (C), you’re missing the fact that the scope of the conclusion here relates to the diagnosis of sociopathy later in life. Answer choice (C) merely suggests that there is a correlation between detention in juvenile hall as a youth and antisocial behavior later in life. Just because two factors are correlated does not mean that one is the cause of the other. Some other factor could have been responsible for the antisocial behavior exhibited later in life. Answer choice (D) is a better choice.
If you chose (E), remember to be suspicious of unrelated statistics on GMAT Critical Reasoning. Just because less than 50% of sociopaths reported they spent < 1 year in juvenile delinquent facilities does not mean that the two factors are related. This answer choice merely suggests a correlation between two factors.
- Which of the following, if true, would bolster the McDonald’s manager’s interpretation?
According to the poll, customers who ordinarily super-sized their orders tended to order less food when the specials menu was not displayed.
80% percent of those surveyed who ordered the super-sized meals did not order a special.
When the specials menu was taken down to be cleaned, no one purchased any specials.
Most of the customers who super-sized their orders responded that they had seen the specials menu prior to ordering.
The Burger King restaurant next door without a specials menu reported fewer “super-size” sales than the surveyed restaurant.
If you chose (B), this answer choice does not help relate the visual cue of the specials menu to ordering a super-size meal, and therefore would not bolster the manager’s conclusion.
If you chose (C), this choice is out of scope. The argument is only concerned with linking the visual images of food to the increased number of “super-sized” orders. The ordering of the specials themselves is tertiary.
If you chose (D), just because seeing the specials menu and super-sizing an order are correlated does not mean that there is a cause/effect relationship between the two variables. Customers may have ordered super-sized meals for any number of reasons other than seeing the specials menu prior to ordering. For example, if the super-sized orders came with a free drink, customers may prefer super-sized orders for that reason.
If you chose (E), there could be many reasons why Burger King next door had fewer “super-size” sales than the surveyed restaurant. This choice is far too vague. Look for a more specific choice to bolster the manager’s interpretation: that “seeing” pictures of food leads to ordering more food.
- All of the following statements, if true for last year, could help to explain the profit growth EXCEPT:
Wobsqua grass is highly desirable as an import-crop for its energy production potential, but is no longer widely considered a useful food source for grazing animals, so overall importing has actually decreased.
The price of raw fuel, needed to power harvesting machines for Wobsqua grass, decreased by 20% overall in the past decade.
Interest in developing alternative energy sources led the United Nations to subsidize Wobsqua grass production in many principalities.
Wobsqua grass farmers, once relegated to the periphery of farmers' associations, have created their own cooperative association to share in common costs like lobbying government.
Newly developed technology for Wobsqua grass harvesting was introduced, allowing some of the work that could previously only be done manually to be done by means of the new technology.
