GMAT AWA Unstated Assumptions Quiz

1. An argument states: 'Company X increased advertising spending by 20%, and sales rose 15% the following quarter. Therefore, the advertising campaign caused the sales increase.' Which unstated assumption does this argument rely on?

Advertising is the only factor that influences sales

No other market conditions changed during that quarter

Sales would have remained flat without the advertising increase

All of the above

The argument assumes that advertising is the sole influence on sales, disregarding other potential factors like market conditions or consumer behavior. It implies that without the increased advertising, sales would not have risen at all. Thus, the conclusion about the effectiveness of the advertising campaign relies on these unexamined assumptions.

Explanation

The argument assumes that advertising is the sole influence on sales, disregarding other potential factors like market conditions or consumer behavior. It implies that without the increased advertising, sales would not have risen at all. Thus, the conclusion about the effectiveness of the advertising campaign relies on these unexamined assumptions.

2. A politician argues: 'Our city's crime rate decreased after we hired 200 additional police officers. We should hire 500 more to cut crime in half.' What assumption underlies this argument?

Crime reduction is directly proportional to the number of officers hired

Hiring more officers will continue to reduce crime at the same rate

No other factors contributed to the crime decrease

Both A and B

The politician's argument relies on the assumption that increasing the number of police officers will lead to a proportional reduction in crime and that this effect will continue consistently. It overlooks other potential factors that may have contributed to the initial decrease in crime, thus simplifying the relationship between police presence and crime rates.

Explanation

The politician's argument relies on the assumption that increasing the number of police officers will lead to a proportional reduction in crime and that this effect will continue consistently. It overlooks other potential factors that may have contributed to the initial decrease in crime, thus simplifying the relationship between police presence and crime rates.

3. An argument claims: 'University graduates earn 40% more than high school graduates on average. Therefore, attending university guarantees financial success.' Which unstated assumption is most critical to this argument?

All graduates find jobs in their field

Higher earnings are solely due to the degree obtained

Financial success depends only on earning potential

University is affordable for all students

The argument assumes that the increased earnings of university graduates are directly attributable to their degrees, ignoring other factors that might contribute to financial success, such as experience, networking, or field of employment. This assumption is critical, as it underpins the conclusion that a university education guarantees higher income.

Explanation

The argument assumes that the increased earnings of university graduates are directly attributable to their degrees, ignoring other factors that might contribute to financial success, such as experience, networking, or field of employment. This assumption is critical, as it underpins the conclusion that a university education guarantees higher income.

4. A company argues: 'Our new product is better than competitors' because it has more features.' What unstated assumption does this rely on?

More features always mean better quality

Customers value all features equally

Price is not a consideration for buyers

The additional features actually work well

The company's argument assumes that an increase in features directly correlates with improved quality. This overlooks the possibility that more features may not enhance the overall user experience or effectiveness of the product, leading to the flawed conclusion that quantity equates to superiority.

Explanation

The company's argument assumes that an increase in features directly correlates with improved quality. This overlooks the possibility that more features may not enhance the overall user experience or effectiveness of the product, leading to the flawed conclusion that quantity equates to superiority.

5. An argument states: 'Students who attend tutoring sessions improve their test scores. Therefore, tutoring is the cause of score improvement.' What assumption is not stated?

Students who seek tutoring would not improve without it

Tutoring is the only factor affecting test performance

Students attending tutoring are not already high achievers

All of the above

The argument assumes that tutoring is the sole factor leading to score improvement, disregarding other potential influences. It also implies that students who seek tutoring would not have improved without it and assumes that these students are not already high achievers. All these assumptions are crucial for the argument's validity.

Explanation

The argument assumes that tutoring is the sole factor leading to score improvement, disregarding other potential influences. It also implies that students who seek tutoring would not have improved without it and assumes that these students are not already high achievers. All these assumptions are crucial for the argument's validity.

6. A researcher argues: 'Countries with higher coffee consumption have lower depression rates. Therefore, drinking coffee reduces depression.' Which assumption is problematic?

Correlation proves causation

No other variables explain the relationship

Depression rates are accurately measured across countries

Coffee is the only difference between these countries

The assumption that correlation proves causation is problematic because it overlooks the possibility that other factors may influence both coffee consumption and depression rates. Just because two variables are correlated does not imply that one causes the other; there could be confounding variables at play that affect the observed relationship.

Explanation

The assumption that correlation proves causation is problematic because it overlooks the possibility that other factors may influence both coffee consumption and depression rates. Just because two variables are correlated does not imply that one causes the other; there could be confounding variables at play that affect the observed relationship.

7. An argument claims: 'Company Y's stock price doubled after hiring a new CEO. The new CEO caused this success.' What unstated assumption might be false?

The CEO's arrival preceded the stock increase

No market-wide factors contributed to the rise

The CEO alone was responsible for performance

Stock price reflects company success accurately

The argument assumes that the CEO is the sole reason for the stock price increase, overlooking other potential influences such as market conditions, company strategies, or external economic factors. This assumption could be false, as multiple variables can contribute to stock performance, making it inaccurate to attribute success solely to the CEO's arrival.

Explanation

The argument assumes that the CEO is the sole reason for the stock price increase, overlooking other potential influences such as market conditions, company strategies, or external economic factors. This assumption could be false, as multiple variables can contribute to stock performance, making it inaccurate to attribute success solely to the CEO's arrival.

8. An argument states: 'Schools with newer buildings have higher test scores. Therefore, building renovations improve student performance.' What assumption is unstated?

Newer buildings directly cause better teaching

Wealthier districts can afford both new buildings and better resources

Building age is the only difference between schools

Both A and B

The argument assumes that newer buildings lead to improved teaching quality and that wealthier districts, which can afford new buildings, also provide better educational resources. This implies that building age is not the sole factor influencing test scores, but rather a combination of infrastructure and financial investment in education.

Explanation

The argument assumes that newer buildings lead to improved teaching quality and that wealthier districts, which can afford new buildings, also provide better educational resources. This implies that building age is not the sole factor influencing test scores, but rather a combination of infrastructure and financial investment in education.

9. A marketing claim states: 'Customers who use our app report higher satisfaction. Buy our app to be satisfied.' Which unstated assumption is problematic?

The app causes satisfaction rather than satisfied customers choosing it

All customers have the same satisfaction criteria

Satisfaction is measurable and objective

The app is the only satisfaction-related purchase

This assumption implies a direct causal relationship between app usage and customer satisfaction, overlooking the possibility that inherently satisfied customers may be more inclined to choose the app. It fails to consider other factors influencing satisfaction, making it a flawed basis for the marketing claim.

Explanation

This assumption implies a direct causal relationship between app usage and customer satisfaction, overlooking the possibility that inherently satisfied customers may be more inclined to choose the app. It fails to consider other factors influencing satisfaction, making it a flawed basis for the marketing claim.

10. An argument claims: 'Exercise increases life expectancy because health-conscious people who exercise live longer.' What unstated assumption does this contain?

Exercise alone accounts for longevity differences

Health-conscious people exercise as their only healthy habit

Genetics and diet do not significantly affect lifespan

All of the above

The argument assumes that exercise is the primary factor influencing longevity, disregarding other potential influences like genetics and diet. It implies that health-conscious individuals rely solely on exercise for their well-being, overlooking other healthy habits they may practice. Therefore, it assumes that these factors do not significantly contribute to lifespan differences.

Explanation

The argument assumes that exercise is the primary factor influencing longevity, disregarding other potential influences like genetics and diet. It implies that health-conscious individuals rely solely on exercise for their well-being, overlooking other healthy habits they may practice. Therefore, it assumes that these factors do not significantly contribute to lifespan differences.

11. An argument states: 'Countries that ban certain pesticides have lower cancer rates. Therefore, banning pesticides reduces cancer.' What hidden assumption is crucial?

Pesticide exposure is the primary cancer cause

No other environmental factors differ between countries

Cancer rates are equally well-reported everywhere

Pesticides are the only chemical exposure difference

The argument assumes that pesticide exposure is the main factor contributing to cancer rates. If other significant causes of cancer are present, the correlation between banning pesticides and lower cancer rates may not imply causation. This assumption is essential to validate the claim that banning pesticides directly leads to reduced cancer incidence.

Explanation

The argument assumes that pesticide exposure is the main factor contributing to cancer rates. If other significant causes of cancer are present, the correlation between banning pesticides and lower cancer rates may not imply causation. This assumption is essential to validate the claim that banning pesticides directly leads to reduced cancer incidence.

12. A study argues: 'People who read books daily earn higher incomes. Therefore, reading books causes financial success.' What unstated assumption is most questionable?

Reading ability is equally distributed across income groups

Reading is the sole factor in earning potential

Education level and reading habits are unrelated

Reading directly generates income

The assumption that reading is the sole factor in earning potential overlooks other significant influences such as education, experience, networking, and skills. Financial success is typically the result of a combination of various factors, making it overly simplistic to attribute it solely to reading habits.

Explanation

The assumption that reading is the sole factor in earning potential overlooks other significant influences such as education, experience, networking, and skills. Financial success is typically the result of a combination of various factors, making it overly simplistic to attribute it solely to reading habits.

13. An argument claims: 'Fast-food restaurants near schools correlate with childhood obesity. Fast-food availability causes obesity in children.' What assumption is unstated?

Location proximity determines eating behavior

No other factors influence childhood weight

Schools in lower-income areas have both fast food and obesity

Both A and B

14. An argument states: 'Employees who work from home report higher productivity. Companies should allow all employees to work remotely.' Which unstated assumption might not hold?

Remote work suits all job types equally

Self-reported productivity is accurate

Remote workers are not already self-motivated

Company culture remains unaffected by remote work

15. An argument claims: 'Students who attend private schools score higher on standardized tests. Private school education is superior.' What critical unstated assumption might be flawed?

Private school quality causes higher scores

Student selection bias does not affect the comparison

Family income and parental education are irrelevant

Both B and C
