GMAT Verbal Reasoning

A recent study of 2,000 employees across ten multinational corporations found that those who worked from home at least three days per week reported 25% higher job satisfaction than those who commuted daily. Based on these results, a consulting firm recommended that all companies adopt a permanent work-from-home policy. Which of the following, if true, most weakens the consulting firm's recommendation?

A Employees who worked from home were more likely to be in technology and creative industries, which naturally have higher satisfaction rates regardless of work location.

B The study did not include employees who worked in manufacturing, retail, or healthcare sectors.

C Some employees who worked from home reported feeling isolated and struggling with work-life boundaries.

D Companies that allowed remote work also offered other benefits such as flexible hours and additional vacation days.

GMAT Verbal Reasoning

A government agency wants to reduce sugar consumption among children. It proposes a 30% tax on sugary drinks. The agency points to a city that implemented a similar tax five years ago and found that per-capita sugary drink sales in that city dropped by 25% in the first year. The agency predicts a similar percentage decline nationwide. Which of the following, if true, most strongly suggests that the nationwide prediction would be inaccurate?

A The city that implemented the tax had a per capita income significantly higher than the national average.

B In the city where the tax was implemented, a concurrent public health campaign against sugary drinks was launched simultaneously with the tax.

C Sugary drink sales nationwide have been declining gradually over the past decade due to increased health awareness, independent of any tax policy.

D The 25% drop in sugary drink sales in the taxed city was partially offset by an increase in sales of bottled water and juice.

GMAT Verbal Reasoning

A national survey found that states with the highest per-student spending on K-12 education also tend to have the lowest student performance on standardized tests. Based on these findings, a policy analyst recommends that states reduce education spending per student in order to improve test scores. Which of the following, if true, most seriously weakens the policy analyst's recommendation?

A States with higher overall budgets tend to spend more on education and also have higher standards for what is included in per-student spending calculations.

B Some states with low per-student spending have also achieved high student performance on standardized tests.

C Student performance on standardized tests is influenced by factors such as poverty rates, parental education levels, and class sizes, which are not directly addressed by changes in per-student spending alone.

D The states with the highest per-student spending also tend to have the highest costs of living, which means that higher spending does not necessarily translate into better educational resources.

GMAT Verbal Reasoning

A software company noticed that its customer support response times improved by 30% after switching from email-based support to a live chat system. The company president concludes that live chat is inherently more efficient than email for customer support and recommends that all other companies make the same switch. Which of the following, if true, most strongly suggests that the president's recommendation would not achieve its intended effect at other companies?

A The software company's customer support team was simultaneously trained in new troubleshooting techniques when the switch to live chat was made.

B Live chat systems require customers to have stable internet connections, which may not be available to all customer populations.

C Email-based support allows customers to attach screenshots and logs, which can sometimes speed up problem resolution.

D The software company serves a primarily technical customer base that tends to have simpler, more common questions than most industries.

GRE Verbal Reasoning

A city implemented a curfew that prohibited minors from being in public places between 10 PM and 5 AM. Within three months, the city reported a 25 percent decrease in nighttime juvenile crime. The police chief credited the curfew for the reduction, arguing that keeping minors at home directly reduced their opportunity to commit or become victims of crime. Which of the following, if true, most weakens the police chief's argument?

A The 25 percent decrease in nighttime juvenile crime was offset by a 20 percent increase in daytime juvenile crime during the same period.

B The curfew was similarly implemented in five other cities, and all five experienced decreases in nighttime juvenile crime.

C Prior to the curfew, the city had already experienced a gradual decline in juvenile crime over the preceding two years.

D Many parents reported that they were already keeping their minors at home during the curfew hours before the law was enacted.

GRE Verbal Reasoning

The city's housing crisis has been attributed to a confluence of factors: restrictive zoning laws that limit new construction, a surge in population driven by tech industry growth, and stagnant wage growth that leaves working families priced out of the market. Some policymakers propose tearing up the zoning maps entirely and allowing unrestricted development. Others argue this would destroy neighbourhood character and flood areas with high-rise buildings incompatible with existing infrastructure. A third group advocates for inclusionary zoning — requiring developers to allocate a percentage of new units to affordable housing — but critics say this merely shifts the burden onto those already struggling. Which of the following, if true, would most weaken the argument against unrestricted development?

A Neighbourhood character is an important value to many residents.

B Cities that have allowed unrestricted development have successfully upgraded their infrastructure to accommodate growth.

C Inclusionary zoning has increased housing costs in some cities.

D The tech industry is expected to continue growing for the next five years.

GRE Verbal Reasoning

A government report claims that a new literacy program has significantly improved reading scores among third-grade students. The report compares the average scores of students who participated in the program to the scores of students in a neighboring district who did not participate. Which of the following, if true, most weakens the argument that the program caused the improvement?

A The participating students came from schools that had twice the funding per student compared to the non-participating schools.

B The literacy program was implemented in the fall, and reading scores were measured only three months later.

C Some parents in the participating district complained that the program took too much time away from other subjects.

D The neighboring district uses a different standardized test than the participating district.

GMAT Verbal Reasoning

A tech company noticed that its most productive software engineers all arrived between 7 and 9 a.m. and took lunch breaks between 11 a.m. and 1 p.m. The company decided to mandate these hours for all employees, arguing that this schedule would maximize overall productivity. Which of the following, if true, most seriously weakens the company's plan?

A Some of the most productive engineers reported that they arrived early because they preferred a quiet office environment before other employees arrived.

B The productivity of the engineers was measured by the number of lines of code written, which does not account for code quality or teamwork contributions.

C Not all of the most productive engineers took lunch breaks within the specified two-hour window; some ate between 12 p.m. and 2 p.m.

D The company's software engineering team includes individuals with different chronotypes, and forcing a uniform schedule may disrupt the natural productivity cycles of night-oriented workers.
