A study of high-growth technology startups established over the past decade revealed that every company that achieved a valuation exceeding one billion dollars was co-founded by an executive with prior experience in enterprise software. Based on this finding, a venture capital analyst argued that in order to ensure a newly launched biotechnology startup achieves a billion-dollar valuation, the founding team must simply hire a former enterprise software executive.

Which of the following best describes the flaw in the venture capital analyst's reasoning?

Cevabı ve açıklamayı göster

Cevap: Treats a factor that was present in successful past cases as though it were a sufficient condition to guarantee future success.

Cevap

The argument flaw is best described as treating a factor observed in past successful cases as a sufficient condition to guarantee future success.
The argument observes that a specific factor (having an enterprise software executive) was present in all past billion-dollar startups. However, assuming that introducing this single factor into a new company will guarantee a billion-dollar valuation mistakes a correlated or historical feature for a sufficient cause.

Adım Adım Çözüm

1
Identify the premise and conclusion of the argument.
Premise: All billion-dollar startups studied in the past decade had a co-founder with enterprise software experience. Conclusion: Hiring a former software executive will ensure a new biotech startup achieves a billion-dollar valuation.
Isolating the core structure reveals the logical gap between the factual evidence and the recommendation.
2
Analyze the logical gap in the inference.
Even if every successful past startup possessed this characteristic, possessing it does not guarantee success. The analyst mistakes a co-occurring trait for a sufficient condition that automatically produces the outcome.
Identifying the misuse of conditional logic (confusing necessary or correlated conditions with sufficient conditions) pins down the flaw.
3
Select the option that accurately describes this conditional logic error.
The option stating that the argument treats a factor present in past success as a sufficient condition for future success precisely captures this reasoning vulnerability.
This directly matches the identified logical flaw without bringing in irrelevant external scope.

A recent urban planning study analyzed twenty metropolitan areas and observed that cities with a high density of public parks reported significantly lower average stress levels among residents than did cities with fewer public parks. The study's authors concluded that expanding green spaces within urban centers directly improves the psychological well-being of city residents. Consequently, municipal leaders in City X plan to convert several commercial districts into public parks in order to reduce resident stress levels.

Which of the following best describes the flaw in the argument's reasoning?

Cevabı ve açıklamayı göster

Cevap: It infers a direct causal relationship between public parks and reduced stress based merely on an observed correlation between the two, ignoring alternative explanations such as reverse causation or underlying socioeconomic factors.

Cevap

The correct choice is the option stating that the argument infers a direct causal relationship based merely on an observed correlation between public parks and reduced stress, ignoring alternative explanations such as reverse causation or underlying socioeconomic factors.
The argument commits a classic correlation-versus-causation flaw. It notes an association between high park density and lower resident stress across cities, then immediately assumes that adding parks directly causes stress reduction. It overlooks plausible alternative explanations—for instance, that wealthier cities with lower overall stress have greater municipal budgets to build parks, or that third factors such as lower population density cause both high park acreage and low stress levels.

Adım Adım Çözüm

1
Deconstruct the argument into premise and conclusion.
Premise: Cities with high park density have lower average resident stress. Conclusion: Expanding green spaces directly improves psychological well-being and will reduce stress in City X.
Isolating the premise and conclusion reveals where the author makes a logical leap in moving from data to a recommendation.
2
Evaluate the logical connection between the premise and conclusion.
The argument observes a statistical correlation (park density and lower stress) and jumps to a direct causal claim (parks cause lower stress).
Observing that two factors co-occur across cities does not prove that one directly causes the other; a third variable (e.g., higher city budget/wealth) or reverse causality (happier/wealthier cities build more parks) could explain the pattern.
3
Match the identified flaw with the choice descriptions.
The option identifying the leap from correlation to causation accurately describes the structural defect in the author's reasoning.
This directly pinpoints the correlation-versus-causation fallacy embedded in the passage.

A regional logistics firm upgraded its ground delivery fleet management software to an automated, predictive routing system. During the six months following the upgrade, the firm recorded a 15 percent decrease in total fuel consumption across all ground routes. The chief operating officer concluded that the new software directly caused the improved fuel efficiency, and subsequently recommended implementing the exact same system across the company's container shipping vessel fleet to achieve an identical 15 percent fuel reduction. Which of the following statements describe logical vulnerabilities in the chief operating officer's reasoning? Select all that apply.

Cevabı ve açıklamayı göster

Cevap: The reasoning fails to account for alternative explanations, such as seasonal weather changes or fluctuations in cargo load weight, that could account for the observed reduction in fuel consumption.; The reasoning improperly assumes that fuel savings achieved in ground delivery operations will automatically translate in the same proportion to maritime container shipping.

Cevap

The correct evaluations are the statement noting that the argument fails to account for alternative explanations such as weather or load shifts, and the statement highlighting the improper assumption that ground fleet results apply proportionally to maritime vessels.
The argument suffers from two distinct logical flaws. First, it assumes that because fuel reduction followed the software installation, the software must have caused the reduction, ignoring other potential factors like load weight or seasonal weather changes. Second, it assumes that performance metrics achieved in ground vehicle delivery can be extrapolated directly to maritime vessel shipping, which operates under entirely different mechanics and conditions. The two correct statements pinpoint these exact flaws.

Adım Adım Çözüm

1
Analyze the premises and conclusion of the stimulus argument.
Premise 1: Software upgraded in ground fleet. Premise 2: Fuel consumption dropped 15% over six months. Conclusion 1: Software caused the drop. Conclusion 2: Installing the same software in maritime shipping will yield an identical 15% drop.
Isolating the structure highlights two core leaps: inferring causation from temporal sequence, and extrapolating results across completely different operational domains.
2
Evaluate candidate vulnerabilities against the argument's logical leaps.
The statement regarding alternative explanations correctly highlights the correlation-causation error. The statement regarding ground versus maritime operations correctly highlights the flawed extrapolation error.
Both selected statements directly address logical gaps in how the evidence is used to reach the ultimate recommendation.
3
Eliminate incorrect distractors based on passage evidence and prompt direction.
The statement about route selection contradicts the passage's claim of all routes being included; the statement about primary objective shifts scope away from fuel efficiency; and the statement claiming to reinforce the conclusion reverses the directional goal of identifying flaws.
Distractors fall into scope errors, factual misreadings of the text, or directional reversals.

A five-year study conducted across several agricultural counties in Region X revealed that farms implementing organic soil-enrichment protocols experienced a 30 percent increase in overall crop yields compared to the preceding five-year period. During the same five-year interval, regional precipitation levels reached historic highs. The researchers concluded that the adoption of organic soil-enrichment protocols was directly responsible for increasing crop yield productivity, and recommended that all agricultural enterprises in neighbouring Region Y immediately adopt these protocols to achieve identical yield improvements.

Which of the following statements accurately describe flaws in the reasoning of the researchers' argument?

Geçerli olan tümünü seçin

Cevabı ve açıklamayı göster

Cevap: The argument infers a direct causal relationship between organic soil protocols and crop yield increases while failing to address the potential confounding effect of concurrent historic rainfall.; The argument presumes without justification that the agricultural conditions and baseline environment in Region Y are sufficiently similar to those in Region X to yield identical outcomes.

Cevap

The argument contains two main logical flaws: first, it assumes a causal connection between the organic soil protocols and increased crop yields while ignoring the alternative cause of record-high precipitation; second, it improperly extrapolates the results from Region X to Region Y without demonstrating that the two regions share equivalent agricultural conditions.
The correct evaluations recognize two central vulnerabilities in the argument's logic. First, the argument commits a correlation-versus-causation error by crediting organic soil protocols for crop yield increases while neglecting the confounding role of historic precipitation levels during the exact same period. Second, the argument commits an improper extrapolation error by assuming that Region Y will replicate Region X's results without establishing that both regions share identical environmental and agricultural parameters.

Adım Adım Çözüm

1
Deconstruct the stimulus into premises and conclusion.
Premise 1: Region X farms using organic protocols saw a 30% yield increase over 5 years. Premise 2: Precipitation reached historic highs during those same 5 years. Conclusion 1: Organic protocols caused the yield increase. Conclusion 2: Region Y should adopt these protocols to obtain identical yield improvements.
Isolating premises and conclusions allows clear identification of unaddressed alternative causes and missing logical bridges.
2
Evaluate the causal leap between soil protocols and yield increases.
The argument attributes the yield increase entirely to the organic soil protocols, ignoring the concurrent historic precipitation that could independently or partially account for the crop growth.
Failing to rule out an obvious co-occurring alternative cause constitutes a classic correlation-versus-causation error.
3
Evaluate the recommendation made for Region Y based on Region X data.
The argument recommends Region Y adopt the protocol to achieve 'identical yield improvements', assuming without proof that Region Y has identical baseline soil, climate, and growing conditions.
Extrapolating findings from one geographic or environmental context to another requires demonstrating that relevant conditions between the two contexts are comparable.

To reduce thirty-day hospital readmission rates for chronic heart failure patients, a regional medical center implemented a daily tele-health monitoring protocol for all such patients discharged during the past calendar year. Over the subsequent twelve months, thirty-day readmissions for chronic heart failure dropped by 18 percent, while patient satisfaction scores across the cardiology department increased significantly. Based on these results, the chief administrator concluded that extending the tele-health monitoring protocol to all outpatient surgical departments will achieve a similar reduction in thirty-day readmissions across all surgical specialties.

Which of the following accurately describe vulnerabilities in the chief administrator's reasoning? Select all that apply.

Cevabı ve açıklamayı göster

Cevap: It presumes without justification that an intervention effective for managing a chronic medical condition will produce comparable outcomes when applied to post-operative surgical care.; It attributes the reduction in readmission rates solely to the tele-health protocol without ruling out concurrent external factors or institutional changes.

Cevap

The argument is vulnerable because it improperly extrapolates results from chronic care to post-surgical care and assumes the tele-health protocol was the sole cause of reduced readmissions without accounting for alternative factors.
The argument exhibits two distinct logical flaws. First, it assumes that a tele-health protocol designed for chronic heart failure management will yield identical benefits for outpatient surgical care, ignoring the distinct medical requirements of post-operative recovery. Second, it treats the temporal sequence of the tele-health implementation and the decline in readmissions as definitive proof of cause and effect, failing to consider alternative causes such as changes in hospital discharge guidelines or staffing levels during that year.

Adım Adım Çözüm

1
Analyze the argument's premises and conclusion
Premises: Tele-health monitoring for chronic heart failure patients was followed by an 18% drop in readmissions and higher satisfaction over one year. Conclusion: Expanding tele-health to outpatient surgical departments will yield similar readmission reductions.
Identifying the structural components clarifies the gap between the evidence provided and the claim made.
2
Evaluate logical gaps in the transition from premises to conclusion
Two main flaws emerge: (1) Overgeneralization from chronic illness care to post-operative surgical care, and (2) Assuming correlation equals causation without excluding concurrent confounding variables.
Exposing missing assumptions and causal leaps allows for precise evaluation of the option choices.
3
Evaluate each option statement against the identified flaws
The option addressing extrapolation to surgical care accurately pinpoints the scope flaw. The option addressing unruled-out concurrent factors accurately pinpoints the causal flaw. The remaining options misstate the evidence or claim flaws that do not exist in the passage.

A recent survey of urban professionals found that individuals who drink green tea daily report significantly lower stress levels than those who do not drink green tea. Based on this finding, a health consultant concluded that drinking green tea directly causes a reduction in stress levels. Which of the following best describes the flaw in the health consultant's reasoning?

Cevabı ve açıklamayı göster

Cevap: It assumes that a correlation between green tea consumption and lower stress proves that green tea causes the reduction in stress.

Cevap

The argument flawedly assumes that because green tea consumption and lower stress occur together, green tea directly causes the lower stress levels.
The correct answer accurately points out that the author confuses correlation with causation. Merely observing that green tea drinkers have lower stress does not prove that green tea causes the reduced stress, as other factors (such as exercise or meditation habits) might be responsible.

Adım Adım Çözüm

1
Identify the argument's premises and conclusion.
Premise: Daily green tea drinkers report lower stress than non-tea drinkers. Conclusion: Drinking green tea directly causes lower stress.
Isolating the structure highlights the leap made between the premise evidence and the author's claim.
2
Evaluate the logical connection between the premise and conclusion.
The author observes a correlation (two things happening together) and immediately infers a direct cause-and-effect relationship.
Correlation alone does not prove causation; alternative explanations (e.g., green tea drinkers might have healthier overall lifestyles) could explain the lower stress.

Cevap: It treats a correlation between Wi-Fi availability and high satisfaction ratings as evidence of a direct causal relationship.; It assumes without justification that commuters on routes currently lacking Wi-Fi will respond to the amenity in the same manner as commuters on existing Wi-Fi routes.

Cevap

The argument is flawed because it mistakes a correlation between Wi-Fi availability and satisfaction for direct causation, and it improperly projects survey results from one set of routes onto all remaining routes without considering differing conditions.
The argument suffers from two primary reasoning flaws: first, it assumes that Wi-Fi availability is the direct cause of higher passenger satisfaction, ignoring possible alternative causes such as newer vehicles or better route reliability; second, it assumes that commuters on remaining routes will react identically to Wi-Fi installation, ignoring potential variations in passenger needs and trip durations.

A historical study of sixteenth-century European merchant guilds revealed that guilds whose members adopted standardized accounting practices survived, on average, forty years longer than guilds that did not adopt such practices. Researchers concluded from this data that implementing standardized accounting practices directly enhanced a guild's operational resilience, enabling it to withstand severe market downturns. Which of the following best describes the flaw in the argument's reasoning?

Cevabı ve açıklamayı göster

Cevap: It concludes that a causal relationship exists between accounting practices and guild longevity when the evidence might instead reflect that older, financially stable guilds were simply more capable of adopting standardized practices.

Cevap

The argument commits a correlation-versus-causation flaw by inferring that standardized accounting caused guild longevity, without accounting for the possibility of reverse causality—that longer-lasting, well-established guilds possessed the resources to adopt such practices.
The correct answer identifies the fundamental logical vulnerability in moving from an observed association (standardized accounting co-occurring with longer guild survival) to a definitive causal assertion (accounting enhanced resilience). It highlights the possibility of reverse causality: surviving longer and accumulating organizational wealth may be what enabled guilds to standardize their accounting in the first place.

Adım Adım Çözüm

1
Analyze the premise and conclusion structure of the stimulus.
Premise: Guilds adopting standardized accounting lived 40 years longer on average than those that did not. Conclusion: Standardized accounting directly enhanced guild resilience and caused longer survival.
Isolating the gap between the empirical observation (correlation) and the author's causal claim is necessary to evaluate argument validity.
2
Identify alternative interpretations of the observed correlation.
The observed correlation could mean (1) accounting caused longevity, (2) longevity/wealth caused accounting adoption (reverse causality), or (3) a third factor caused both.
A valid causal claim must rule out plausibly competing causal directions or third-variable explanations.

Cevap: It fails to account for alternative explanations, such as regional weather changes or mandatory conservation restrictions, that could account for the decline in water usage.; It infers that the rebate program caused the overall usage decline without establishing whether the reduction occurred primarily among households that adopted the smart controllers.

Cevap

The argument contains logical vulnerabilities by failing to account for alternative external causes for the water reduction and by failing to demonstrate that the usage reduction actually occurred among the households that installed the smart controllers.
The correct options properly identify two major flaws in the author's causal claim. First, inferring cause directly from temporal sequence ignores external confounding factors (such as rainfall anomalies or citywide conservation mandates). Second, attributing an aggregate decline in water usage to a specific program requires evidence that the decline occurred within the targeted group rather than among non-participants.

The argument's reasoning is flawed because it infers a direct causal link from a mere correlation, failing to consider that alternative factors—such as the fame or appeal of the artworks displayed in those specific galleries—could explain why visitors remained there longer.
The correct choice highlights the classic correlation-versus-causation fallacy present in the argument.

The valid flaws in the argument are the statement pointing out that a causal relationship is improperly inferred from a mere correlation, and the statement highlighting the unjustified assumption that course difficulty and grading standards were equal across departments.
The argument suffers from two central vulnerabilities. First, it commits a correlation-versus-causation fallacy by assuming that lower scores in departments with recordings were caused by the recordings themselves, rather than considering alternative factors (such as struggling students enrolling in those courses or recordings being offered in harder subjects). Second, it relies on an unstated assumption that the courses in both sets of departments were comparable in difficulty, student composition, and grading.

Cevap

The argument is vulnerable because it infers a direct causal relationship between two concurrent events without considering alternative factors that could account for the observed change.
The correct answer identifies the fundamental logical error in the argument: assuming that because the introduction of the copper-alloy sanitation protocol preceded and coincided with a decrease in ICU infection rates, the protocol must have caused the decrease. This ignores plausible alternative explanations, such as coincidental seasonal fluctuations in pathogen prevalence or other simultaneous quality-improvement measures implemented by the hospital.

Deconstruct the argument into premise and conclusion.
Premise: Daily copper-alloy sanitation was introduced three months ago, and ICU infections dropped by 40% during those three months. Conclusion: The copper-alloy sanitation protocol directly caused the drop in infections.
Identifying the structural components helps isolate the leap in logic from premise to conclusion.
2
Analyze the logical gap between the premise and the conclusion.
The argument relies on a temporal sequence and correlation (new sanitation introduced → infection rates decreased) to assert a direct causal connection.
Correlated events do not automatically prove causation because unaccounted third variables (e.g., changes in handwashing policy, staff training, seasonal illness changes) could be responsible.
