Consider the following argument regarding urban economic policy:

"While some economists argue that capping rent prices in urban centers protects low-income residents from displacement, empirical data indicates that strict price controls invariably suppress private investment in residential construction. This suppression of capital over time restricts total housing supply, thereby driving up shadow prices in unregulated market sectors. Consequently, although rent control provides immediate relief to current tenants, its overall long-term effect is a net decline in housing accessibility for future residents. Therefore, municipal leaders seeking to broaden housing affordability should implement direct tenant income subsidies rather than statutory price caps."

Match each claim from the passage on the left to its exact structural role and relationship within the overall argument flow on the right.

Cevabı ve açıklamayı göster

Cevap

Each claim matches its corresponding structural role: the investment suppression claim matches the foundational premise regarding supply restriction; the immediate relief claim matches the conceded counter-point; the long-term decline claim matches the intermediate conclusion; and the income subsidy recommendation matches the author's main conclusion.
The argument builds from empirical evidence (suppression of investment) to an intermediate logical consequence (restricted supply leading to long-term decline in accessibility), while explicitly acknowledging a short-term benefit as a concession, all of which culminate in supporting the main policy recommendation to favor income subsidies over price caps.

Adım Adım Çözüm

1
Analyze the main argument structure and identify the final conclusion.
The final sentence beginning with 'Therefore' presents the author's overall recommendation (use income subsidies instead of price caps), establishing it as the main conclusion.
Identifying the main conclusion provides the reference point for evaluating all supporting claims.
2
Determine the role of premises and intermediate steps leading to the main conclusion.
The claim that strict price controls suppress private investment acts as an empirical premise. This leads to restricted supply and higher shadow prices, establishing an intermediate conclusion that the overall long-term effect is a net decline in housing accessibility.
Evaluating how premises build logically upon each other reveals the intermediate conclusion that bridges evidence to the main conclusion.
3
Evaluate transitional indicators and concessions.
The clause introduced by 'although' ('although rent control provides immediate relief to current tenants') acknowledges a localized benefit without undermining the overall argument, identifying it as a concession.
Recognizing concessive transitions clarifies how counter-evidence is integrated into the author's reasoning flow.

Equivocation and Shift in Term Meaning
Soru 44Soru

Read the argument below regarding energy infrastructure and match each statement from the text to its corresponding logical role within the argument.

Argument:
Although utility companies contend that investing in municipal microgrids will fragment national energy markets and raise consumer rates, recent empirical data from regional pilots show that decentralized solar-plus-storage systems significantly reduce peak-demand spikes. Lowering peak-demand strain directly reduces the need for expensive fossil-fuel peaking plants. Consequently, municipal microgrid expansion actually enhances overall grid resilience and long-term cost stability. Therefore, federal energy regulators should mandate municipal microgrid integration standards immediately, despite short-term transition costs for legacy utilities.

Investing in municipal microgrids will fragment national energy markets and raise consumer rates.

Eşleşmeler

Cevabı ve açıklamayı göster

Cevap

The statement urging federal regulators to mandate integration standards matches the Main Conclusion; the statement asserting that microgrid expansion enhances resilience and stability matches the Intermediate Conclusion; the statement regarding reduction of peak-demand spikes matches the Supporting Premise; and the statement about market fragmentation and rate increases matches the Counterargument.
The call for immediate federal integration mandates represents the Main Conclusion because it is the ultimate policy recommendation that the entire argument builds toward. The claim regarding grid resilience and cost stability is an Intermediate Conclusion because it is inferred from empirical pilot data and directly provides the logical justification for the main policy mandate. The finding that solar-plus-storage systems reduce peak-demand spikes is a Supporting Premise containing raw empirical evidence. Finally, the utility companies' position regarding market fragmentation and rate increases is a Counterargument introduced as an opposing stance.

Adım Adım Çözüm

1
Identify the primary thesis or ultimate recommendation of the argument.
The final sentence, introduced by the conclusion indicator 'Therefore,' states that federal regulators should mandate municipal microgrid integration standards immediately.
This prescriptive policy call is the ultimate claim that all other evidence and intermediate claims in the passage aim to prove.
2
Identify intermediate claims that link evidence to the main conclusion.
The sentence introduced by 'Consequently' claims that municipal microgrid expansion enhances overall grid resilience and long-term cost stability.
This claim is supported by the peak-demand evidence and in turn acts as the direct rationale for the final policy mandate, making it an intermediate conclusion.
3
Differentiate empirical evidence from inferred conclusions.
The assertion that decentralized solar-plus-storage systems significantly reduce peak-demand spikes is introduced as empirical data from regional pilots.
It functions as foundational factual evidence (a premise) rather than an inferred statement.
4
Classify opposing claims framed within concessions.
The utility companies' assertion that microgrids fragment markets and raise consumer rates is introduced using the concessionary framing 'Although utility companies contend...'.
This represents an opposing position (counterargument) introduced to establish the context that the author's argument seeks to overcome.

Cevap

The statement regarding trial participants experiencing both side effect W and symptom reduction matches Valid Inference. The statement attributing symptom reduction to pharmacological action rather than external variables matches Unstated Assumption. The statement predicting identical results in general clinical practice matches Speculative Extrapolation.
The item correctly categorizes each claim according to GMAT Critical Reasoning criteria: absolute mathematical overlap derived from premises forms a Valid Inference; presupposed control of background variables forms an Unstated Assumption; and extending trial results to general real-world populations forms a Speculative Extrapolation.

Adım Adım Çözüm

1
Analyze the logical scope of the statement asserting that participants experiencing side effect W also experienced symptom reduction.
Identify that 100% of Drug Y recipients had symptom reduction. Since side effect W occurred exclusively within the Drug Y group (15% of recipients), 100% of those with side effect W necessarily had symptom reduction.
Deductions that must be true strictly based on given set boundaries are valid inferences.
2
Evaluate the statement attributing the trial results to Drug Y rather than external variables.
Recognize that for trial observations to prove drug efficacy, unmentioned confounding variables must be assumed not to have influenced the outcome.
An unstated premise necessary to bridge observed data to a valid conclusion constitutes an assumption.
3
Evaluate the statement predicting general clinical outcomes outside the study.
Determine that broader real-world performance cannot be guaranteed from a single 500-patient trial.
Claims extending beyond the temporal, demographic, or environmental boundaries of given data are speculative extrapolations.

Read the argument below regarding environmental policy and marine mining, then match each statement from the text to its corresponding logical role within the argument:

"Proponents of deep-sea polymetallic nodule mining argue that extracting seabed minerals is essential to supply metals for green technology transitions without expanding terrestrial mining's ecological footprint. However, recent oceanographic surveys indicate that benthic ecosystems recover far more slowly from physical disturbance than land-based biomes do. Because deep-sea sediment plumes can travel hundreds of kilometers, disrupting midwater marine food webs, the environmental costs of abyssal mining are likely to exceed those of conventional land extraction. Therefore, international regulators should institute an immediate moratorium on commercial seabed mining, regardless of projected economic benefits."

Cevap

The statement regarding green technology needs corresponds to the opposing viewpoint; the statement about benthic recovery rates corresponds to a premise offering empirical evidence; the statement asserting environmental costs will exceed terrestrial mining corresponds to an intermediate conclusion; the statement advocating a moratorium corresponds to the main conclusion.
The author uses survey evidence regarding benthic recovery rates and sediment plume movement to support the sub-claim that deep-sea mining costs will exceed terrestrial mining costs. This sub-claim directly justifies the author's primary final claim: that regulators should enact an immediate moratorium on commercial seabed mining. The opening assertion about green technology needs represents the opposing claim being refuted.

Adım Adım Çözüm

1
Identify the author's ultimate goal or main conclusion in the passage.
The final sentence introduced by 'Therefore' recommends that international regulators institute an immediate moratorium on commercial seabed mining.
This is the ultimate recommendation of the passage that all preceding evidence and sub-claims work together to justify.
2
Analyze intermediate claims that connect foundational evidence to the main conclusion.
The claim that abyssal mining costs will exceed land extraction costs is derived from facts about benthic recovery and sediment plumes, but it acts as a supporting reason for the moratorium.
A claim that is inferred from factual premises and simultaneously used to support the final recommendation acts as an intermediate conclusion.
3
Classify remaining premises and background claims.
Survey findings on benthic recovery rates serve as direct empirical evidence (premise), while the opening sentence presents the proponents' claim (opposing viewpoint).
Empirical survey results provide foundational support for the sub-conclusion, whereas proponents' views provide the counter-position being challenged.

Read the argument below regarding biotechnology and invasive species management, and match each statement from the text to its corresponding logical role within the overall argument.

Argument: Conservationists frequently propose gene-drive technology to eradicate invasive species on isolated islands. Critics contend that off-target genetic mutations could inadvertently spread to mainland populations, causing ecological collapse. However, recent field trials utilizing self-limiting genetic markers demonstrate that gene drives decay naturally within five generations, rendering widespread spillover biologically impossible. Although monitoring post-release ecosystems remains essential to detect unexpected ecological shifts, the fear of uncontrolled global spread is unfounded. Consequently, environmental agencies should proceed with controlled island deployments of self-limiting gene drives.

Read the following argument carefully, then match each key term from the argument to the specific shift in meaning it undergoes between the premise context and the conclusion context:

'To ensure market stability, regulatory boards must foster fair competition among competing energy firms. However, fair competition exists only when no firm holds an unfair advantage over its rivals. Because companies holding proprietary patents on green technology possess a clear operational advantage not shared by competitors, patent enforcement violates fair competition.

Cevap

The terms 'Fair competition', 'Unfair advantage', and 'Market stability' each shift from standard regulatory definitions in the premises to overly restrictive, outcome-focused definitions in the conclusion.
The correct pairings accurately pinpoint how each term's scope changes to make an invalid conclusion appear logically valid. 'Fair competition' shifts from impartial rules to equal capabilities; 'unfair advantage' shifts from illegal practice to legal patent ownership; and 'market stability' shifts from structural order to protection from competitive innovation.

Adım Adım Çözüm

1
Analyze how 'fair competition' is introduced in the premise versus how it is applied to patent holders.
The argument moves from procedural fairness (equal rules) to outcome equality (no technological gaps).
This establishes the primary equivocation regarding competitive fairness.
2
Trace the implicit definition of 'unfair advantage'.
The premise implies improper advantage, but the argument equates this with holding valid intellectual property rights.
This shows how a term with negative normative connotations is improperly applied to legal research outcomes.
3
Examine the shift in 'market stability'.
Systemic stability is conflated with insulating existing market actors from competitive pressure.
This completes the logical flaw, demonstrating that the final conclusion rests on shifting definitions rather than sound premises.

Set up the simultaneous linear equations from the text.
s+v=100s + v = 100 and 25s+50v=350025s + 50v = 3500
The total count equation represents total tickets, and the price equation represents total revenue.

Subtract the first equation (s+v=100s + v = 100) from the simplified second equation (s+2v=140s + 2v = 140).
v=40v = 40
Subtracting eliminates the variable ss directly.

Read the argument below regarding retail pricing algorithms, then match each statement from the text to its corresponding logical role within the argument.

Argument:
Although proponents of automated dynamic pricing systems argue that such algorithms merely optimize market efficiency by responding instantly to supply fluctuations, regulators note that concurrent deployment of identical algorithms by competing retailers frequently leads to implicit price coordination. Such algorithmic tacit collusion artificially inflates consumer prices even in the absence of explicit communication among firms. Because existing antitrust laws require proof of explicit agreement to establish illegal price-fixing, current legal frameworks are fundamentally ill-equipped to curb algorithmic collusion. Regulators must therefore update antitrust standards to encompass market outcomes generated by shared pricing algorithms.

Cevap

The correct matches are: 'Security' matches with the shift from technical protection to broad ethical safeguarding; 'Satisfies responsibilities' matches with the shift from technical compliance to fulfilling overall moral duties; and 'External cyberattacks' matches with the shift from technical network intrusions to general breaches of user trust.
The argument commits an equivocation flaw by introducing terms under narrow, technical definitions in the premises and quietly broadening their definitions in the conclusion. 'Security' shifts from technical data protection to comprehensive ethical duty; 'Satisfies responsibilities' shifts from meeting specific software parameters to fulfilling complete moral duties; and 'External cyberattacks' shifts from specific cyber intrusions to any violation of consumer trust.

Adım Adım Çözüm

1
Analyze how the term 'Security' is introduced in the premise versus the conclusion.
The premise restricts 'security' to technical data encryption against cyber threats, whereas the conclusion equates it to broad corporate ethical duties.
Identifying shifts in definition is essential for exposing equivocation flaws.
2
Examine the scope shift in 'Satisfies responsibilities'.
Meeting technical encryption criteria (a narrow obligation) is conflated with fulfilling all ethical duties owed to users.
The argument uses technical compliance to improperly claim total moral compliance.
3
Evaluate the phrase 'External cyberattacks' across contexts.
Preventing unauthorized digital access is assumed to cover all dimensions of user trust and safety.
Conflating a specific threat type with overall user safety illustrates a shift in semantic scope.

Statement 1 strengthens the direct causal claim; Statement 2 demonstrates reverse causality; Statement 3 identifies a confounding common cause.
The correct matches accurately distinguish between evidence supporting direct causation, evidence illustrating reverse causation, and evidence establishing a third-variable confounder.

Adım Adım Çözüm

1
Analyze the researcher's conclusion
The researcher posits a direct causal link: Park construction (Cause) \rightarrow Resident activity (Effect).
Identifying the proposed direction of cause and effect is essential to evaluating logical roles.
2
Evaluate the first statement
The first statement establishes a chronological sequence where the park opening precedes the increase in activity, supporting direct causality.
Evidence showing that the cause precedes the effect strengthens a causal argument.
3
Evaluate the second statement
The second statement shows that active people move to cities with parks, implying activity level (Effect) drives the residency pattern near parks (Cause).
Reversing cause and effect undermines the researcher's claim of direct causality.
4
Evaluate the third statement
The third statement introduces municipal wealth as an alternate factor influencing both park availability and exercise programs.
A third factor causing both observed variables explains the correlation without direct causality.

Cevap

Configuration P fuel consumption per flight is 11,000 gallons; Configuration C fuel consumption per flight is 18,000 gallons.
Solving the linear system 4fP+3fC=98,0004 f_P + 3 f_C = 98,000 and 2fP+5fC=112,0002 f_P + 5 f_C = 112,000 gives fP=11,000f_P = 11,000 gallons and fC=18,000f_C = 18,000 gallons.

Adım Adım Çözüm

1
Formulate a system of simultaneous linear equations based on the problem statement.
Let fPf_P be fuel per Configuration P flight and fCf_C be fuel per Configuration C flight. Equation 1: 4fP+3fC=98,0004 f_P + 3 f_C = 98,000. Equation 2: 2fP+5fC=112,0002 f_P + 5 f_C = 112,000.
Translates the two total fuel conditions into explicit linear equations.
2
Eliminate variable fPf_P by multiplying Equation 2 by 2.
Multiplying Equation 2 by 2 yields 4fP+10fC=224,0004 f_P + 10 f_C = 224,000.
Equalizes the coefficients of fPf_P across both equations to enable cancellation.
3
Subtract Equation 1 from the modified equation to solve for fCf_C.
(4fP+10fC)(4fP+3fC)=224,00098,000    7fC=126,000    fC=18,000(4 f_P + 10 f_C) - (4 f_P + 3 f_C) = 224,000 - 98,000 \implies 7 f_C = 126,000 \implies f_C = 18,000.
Subtracting cancels fPf_P, yielding the fuel consumption per Configuration C flight.
4
Substitute fC=18,000f_C = 18,000 back into Equation 1 to find fPf_P.
4fP+3(18,000)=98,000    4fP+54,000=98,000    4fP=44,000    fP=11,0004 f_P + 3(18,000) = 98,000 \implies 4 f_P + 54,000 = 98,000 \implies 4 f_P = 44,000 \implies f_P = 11,000.
Determines the fuel consumption per Configuration P flight.

Cevap

The statement describing retail merchant lobbying matches the reverse causal relationship role; the statement concerning the launch of a zero-fare light rail line matches the confounding variable role; and the statement regarding transit lines operating at 99% capacity matches the invalidation of a necessary assumption role.
Each argument role correctly aligns with its corresponding logical effect: the merchant lobbying statement reverses the temporal and causal sequence; the zero-fare light rail statement introduces a concurrent external factor driving both observed trends; and the 99% transit capacity statement demonstrates a physical bottleneck that breaks a required link in the board's proposed mechanism.

Adım Adım Çözüm

1
Analyze the board's core causal hypothesis.
Cause = Congestion pricing toll → Effect = Reduced car traffic & increased retail foot traffic via public transit conversion.
Establishing the explicit mechanism (toll → less car congestion → suburban shoppers take transit → higher foot traffic) is necessary to evaluate logical flaws.
2
Evaluate the statement concerning merchant lobbying.
This statement indicates that higher pedestrian traffic came first and caused the political demand for the toll.
This directly reverses the direction of causality (YXY \rightarrow X instead of XYX \rightarrow Y), matching the reverse causal relationship role.
3
Evaluate the statement concerning the zero-fare light rail extension.
The light rail extension introduces an external event occurring at the same time that independently drives both observed trends.
A third factor (ZZ) that causes both decreased vehicle traffic and increased foot traffic constitutes a classic confounding variable alternative explanation.
4
Evaluate the statement concerning transit capacity operating at 99%.
Because transit was already saturated and received no upgrades, it physically could not carry new shoppers into District X.
The board's conclusion hinges on the unstated premise that transit could accommodate modal shift; proving capacity was zero invalidates this necessary assumption.

Read the argument below regarding subglacial Antarctic lake exploration, then match each statement from the text to its corresponding logical role within the argument.

Argument:
Recent drillings into subglacial Antarctic lakes revealed microbial communities surviving in complete darkness. Astrobiologists frequently argue that discovering such extremophiles proves life could easily thrive in the subsurface oceans of icy moons like Europa. However, terrestrial subglacial lakes benefit from geothermal heat sources and chemical influxes from surrounding bedrock that are likely absent on icy celestial bodies. Thus, terrestrial extremophile survival cannot be treated as an exact model for extraterrestrial habitability. Consequently, researchers must establish direct spectroscopic criteria for extraterrestrial life rather than relying on terrestrial analogs.

The statement detailing geothermal heat and chemical influxes functions as a factual premise countering the opposing view. The assertion that extremophiles prove life on Europa represents the opposing position. The claim that terrestrial survival cannot be an exact model is an intermediate sub-conclusion. The final recommendation that researchers must establish direct spectroscopic criteria is the main conclusion of the argument.
The argument builds toward a final actionable recommendation introduced by 'Consequently': researchers must establish direct spectroscopic criteria. The factual statement about geothermal heat serves as a premise leading to the intermediate conclusion ('Thus, terrestrial extremophile survival cannot be treated as an exact model'), which directly supports the ultimate recommendation.

1
Identify the structural pivot and main recommendation in the passage.
The indicator 'Consequently' signals the author's ultimate claim: researchers must establish direct spectroscopic criteria for extraterrestrial life rather than relying on terrestrial analogs.
The main conclusion is the final claim supported by all preceding evidence and sub-conclusions in the argument.
2
Analyze the role of intermediate inferences and opposing claims.
'Thus' signals an intermediate sub-conclusion ('terrestrial extremophile survival cannot be treated as an exact model'), which bridges the premise about heat sources and bedrock influxes to the final recommendation.
Distinguishing between intermediate conclusions and final claims prevents confusing subsidiary steps with the author's ultimate point.
