A national logistics enterprise equipped 60 of its fulfillment centers with automated climate-controlled hydration micro-hubs. Over the subsequent 12-month evaluation period, heat-related employee fatigue incidents across these facilities decreased by 35%. Company executives concluded that the installation of the micro-hubs directly caused the reduction in heat-related fatigue incidents. Match each logical role on the left with the statement on the right that best fulfills it.

Cevap

The statement strengthening the conclusion matches the observation that fatigue drops occurred exclusively where hubs were actively used compared to delayed control centers. The statement providing an alternative explanation matches the facility-wide ventilation upgrade reducing indoor temperatures. The statement illustrating causal direction reversal matches the selection of facilities based on pre-existing fatigue reductions.
The correct pairings establish precise alignment between logical evaluation roles and empirical statements. Isolating the effect to active intervention sites relative to delayed control sites strengthens a causal claim. Identifying simultaneous environmental upgrades provides a confounding alternative explanation. Pointing out that pre-existing drops in fatigue dictated site selection exposes reverse causality and selection bias.

Adım Adım Çözüm

1
Analyze the core causal claim in the stem.
Cause: Installation of hydration micro-hubs. Effect: 35% reduction in heat-related fatigue incidents.
Evaluating causal arguments requires identifying the explicit cause-and-effect structure asserted by the author.
2
Evaluate the statement strengthening the conclusion.
The statement detailing that fatigue decreased only in facilities actively using micro-hubs while remaining constant in control facilities provides a controlled comparison supporting causation.
A valid control group comparison rules out baseline temporal trends.
3
Evaluate the statement providing an alternative explanation.
The statement mentioning ventilation upgrades that reduced ambient temperatures provides a confounding variable that could explain the drop independently of the micro-hubs.
Alternative explanations weaken causal claims by attributing the effect to an unmanaged variable.
4
Evaluate the statement showing causal reversal/selection bias.
The statement showing hubs were installed because fatigue had already dropped demonstrates that prior fatigue trends caused hub allocation, rather than hub allocation causing the drop.
Selection bias occurs when the outcome variable influences treatment assignment.

Cevap: $36,00036,000

Cevap

The total net electricity cost for the facility for May is $36,000 because the reconciled facility energy intensity of approximately 2.09 kWh per unit exceeds the 1.80 kWh per unit threshold required for the 15% rebate.
The correct answer is 36,000.ReconcilingTab1andTab3showstotalelectricityconsumptionof240,000kWh(120,000kWhfromLine1+120,000kWhfromLine2)andnetvalidproductionof115,000units(90,000validunitsfromLine1+25,000validunitsfromLine2).Dividing240,000kWhby115,000unitsyieldsafacilityenergyintensityofapproximately2.09kWhperunit.Because2.09exceedsthe1.80kWhperunitthresholddefinedinTab2,thefacilityfailstoqualifyforthe1536,000. Reconciling Tab 1 and Tab 3 shows total electricity consumption of 240,000 kWh (120,000 kWh from Line 1 + 120,000 kWh from Line 2) and net valid production of 115,000 units (90,000 valid units from Line 1 + 25,000 valid units from Line 2). Dividing 240,000 kWh by 115,000 units yields a facility energy intensity of approximately 2.09 kWh per unit. Because 2.09 exceeds the 1.80 kWh per unit threshold defined in Tab 2, the facility fails to qualify for the 15% rebate discount and pays the standard tariff rate of 0.15 per kWh across all 240,000 kWh, totaling $36,000.

Line 1 energy = 400 hours×300 kWh/hour=120,000 kWh400\text{ hours} \times 300\text{ kWh/hour} = 120,000\text{ kWh}. Line 2 energy = 200 hours×600 kWh/hour=120,000 kWh200\text{ hours} \times 600\text{ kWh/hour} = 120,000\text{ kWh}. Total electricity consumed = 240,000 kWh240,000\text{ kWh}.
Establishing the total power consumption is necessary to determine both energy intensity and base bill calculation.
2
Calculate gross production from Tab 1 and adjust for scrapped units using Tab 3 audit data to find total valid units.
Line 1 gross units = 400×250=100,000400 \times 250 = 100,000; valid units = 100,000×(10.10)=90,000100,000 \times (1 - 0.10) = 90,000.

Total valid units = 90,000+25,000=115,000 units90,000 + 25,000 = 115,000\text{ units}.
Tab 2 defines the energy intensity denominator specifically as valid units produced, requiring reconciliation with Tab 3 scrap rates.

Evaluate the following statement based on the data provided:

'When all 10 stations are ordered by increasing Elevation, there is a strictly monotonic inverse relationship between Elevation and Solar Irradiance.'

Cevabı ve açıklamayı göster

Cevap: False

Cevap

False. The relationship between Elevation and Solar Irradiance is not strictly monotonic because Solar Irradiance increases from ST-04 to ST-05.
The evaluated statement claims a strictly monotonic inverse relationship between Elevation and Solar Irradiance. Checking the values sequentially by increasing elevation shows that Solar Irradiance decreases from ST-01 (5.85.8) through ST-04 (4.94.9), but increases at ST-05 (5.15.1). Consequently, the relationship is not strictly monotonic.

Adım Adım Çözüm

1
Verify table ordering by Elevation
The table is already sorted in ascending order of Elevation from ST-01 (150 m150\text{ m}) to ST-10 (1500 m1500\text{ m}).
To evaluate monotonicity across Elevation, we must inspect Solar Irradiance values sequentially from lowest to highest elevation.
2
Examine Solar Irradiance values sequentially
ST-01: 5.85.8, ST-02: 5.55.5, ST-03: 5.25.2, ST-04: 4.94.9, ST-05: 5.15.1.
A strict inverse monotonic trend requires that every successive value be strictly smaller than the preceding value.
3
Identify non-monotonic exception
Between ST-04 and ST-05, Solar Irradiance increases from 4.9 kWh/m24.9\text{ kWh/m}^2 to 5.1 kWh/m25.1\text{ kWh/m}^2.
Because 5.1>4.95.1 > 4.9, there is a local increase, which invalidates a strict monotonic inverse correlation across the full dataset.

Passage:
Agricultural economists evaluating indigenous agroforestry practices in sub-Saharan West Africa have long documented the ecological benefits of Faidherbia albida, an acacia species that exhibits reverse phenology—shedding its nitrogen-rich leaves during the onset of the rainy season when staple crops such as sorghum and millet are planted. This unusual trait provides crops with organic fertilizer and overhead shade during seedling establishment without competing for light or water during peak growth phases. Recent policy initiatives have sought to scale up Faidherbia integration by offering direct financial subsidies to smallholder farmers based on tree planting density. Proponents argue that subsidizing seedling procurement and land preparation will directly increase long-term crop yields across arid farming communities. However, longitudinal field surveys reveal that smallholder adoption rates remain low despite full subsidy coverage. Researchers hypothesize that the financial burden of purchasing and planting seedlings is not the primary constraint on adoption. Rather, the dominant factor limiting widespread implementation is traditional communal grazing tenure rules, which grant cattle herders unrestricted access to cultivated fields post-harvest. Because free-roaming livestock consume young Faidherbia saplings during the dry season, individual farmers cannot protect their investments regardless of initial planting incentives.

Which of the following is an unstated assumption required by the researchers' hypothesis regarding the cause of the low adoption rates?

Cevabı ve açıklamayı göster

Cevap: Individual smallholder farmers would be capable of successfully protecting young Faidherbia albida saplings from destruction if post-harvest livestock access to their fields were restricted.

Cevap

The researchers' hypothesis assumes that individual smallholder farmers would be capable of successfully protecting young Faidherbia albida saplings if post-harvest livestock access to their fields were restricted.
The researchers' argument concludes that communal grazing rules are the main barrier to Faidherbia albida adoption because livestock consume saplings post-harvest. For this causal explanation to work, it must be true that removing or modifying this barrier would actually allow farmers to protect their trees. If farmers were still unable to protect saplings due to other unmentioned obstacles, then grazing rules could not be identified as the decisive limiting factor. Applying the Negation Test demonstrates that this condition is logically required.

Adım Adım Çözüm

1
Identify the researchers' core hypothesis
The researchers hypothesize that communal grazing rules (unrestricted post-harvest cattle access) are the primary factor limiting tree adoption because free-roaming livestock destroy young saplings.
Understanding the precise causal link between the premise (grazing access) and the conclusion (low adoption) is essential before testing assumptions.
2
Apply the Negation Test to the central claim
Negate the statement: 'Even if livestock access were restricted, farmers would still NOT be capable of protecting young saplings.'
If the negated version is true, restricting grazing access would not help farmers protect saplings, undermining the claim that grazing rules are the primary constraint.
3
Select the option that matches the required necessary assumption
The statement asserting that farmers would be able to protect saplings if access were restricted is a required unstated assumption.
A necessary assumption must leave the argument intact when true and shatter the argument when negated.

Passage:
Recent excavations of Bronze Age slag heaps in Anatolia demonstrate that early metallurgists adapted their smelting furnaces to process complex chalcopyrite ores containing high concentrations of arsenic and antimony. Previous historical models assumed that arsenic-rich copper alloys were produced exclusively through deliberate co-smelting—the intentional addition of separate arsenical minerals to a refined copper melt. However, chemical analysis of slag residues at these Anatolian sites reveals that furnace temperatures were maintained below 1,150 degrees Celsius specifically to prevent the premature volatilization of arsenic already embedded within the raw chalcopyrite ore matrix. By sustaining these moderate thermal conditions, smelters achieved high arsenic retention in the resulting bronze without requiring supplemental mineral additives. Nonetheless, because antimony volatilizes at a significantly lower thermal threshold than arsenic under identical furnace atmospheres, any trace antimony present in the raw ore was entirely lost as vapor during this single-stage process.

Based on the passage premises, evaluate whether the following statement is True or False:
Anatolian metallurgists operating furnaces below 1,150 degrees Celsius would be unable to produce bronze containing antimony from raw chalcopyrite ore using the single-stage smelting process described.

Cevabı ve açıklamayı göster

Cevap: True

Cevap

True
The statement is logically true because the passage establishes that antimony volatilizes at a lower thermal threshold than arsenic under identical furnace conditions. Operating the furnace below 1,150 degrees Celsius causes all antimony in raw chalcopyrite ore to escape as vapor, making it impossible to yield antimony-containing bronze through this single-stage process.

Adım Adım Çözüm

1
Analyze the thermal conditions and chemical behavior stated in the passage.
Furnace temperatures under 1,150 degrees Celsius prevent arsenic volatilization, but antimony volatilizes at a significantly lower thermal threshold than arsenic.
Comparing the volatilization thresholds of arsenic and antimony reveals how each metal behaves during smelting.
2
Deduce the effect of these thermal conditions on antimony present in raw chalcopyrite ore.
Because antimony's threshold is lower than that of arsenic, any antimony in raw ore vaporizes and escapes entirely during single-stage smelting at these temperatures.
Directly applying the premise proves whether antimony remains in the processed alloy.
3
Determine the validity of the statement based on the deduction.
Smelters cannot produce antimony-bearing bronze from raw ore alone using this single-stage method, confirming the statement as True.
The logical conclusion derived from the premises matches the claim made in the statement.

Define variables and establish system equations from the given ratios and constraints.
Let AA, BB, and PP be the masses (in kg) of Formulation Alpha, Formulation Beta, and Pure Additive, respectively. Given A:B=2:1A : B = 2 : 1, we have A=2BA = 2B. The total mass equation is A+B+P=100A + B + P = 100.

Quantitative Data Reconciliation Across Sources
Soru 2050Soru

In municipal water utility governance, "capital-expenditure substitution bias" occurs when an operating authority systematically diverts routine maintenance funding toward high-visibility infrastructure expansion projects. Because public oversight bodies evaluate utility management primarily on tangible asset growth rather than subtle operational reliability metrics, utility directors face strong incentives to launch new construction. Over time, existing underground piping networks undergo unmonitored structural degradation. When minor leaks inevitably manifest, managers routinely absorb the localized repair costs using emergency contingency funds rather than addressing the systemic deferred maintenance. Consequently, while the utility's balance sheet reflects substantial physical asset accumulation, its core distribution grid incurs hidden, compounding risk of catastrophic failure—a failure that is eventually triggered not by an extraordinary environmental stressor, but by routine operational fluctuations that a properly maintained legacy system would easily withstand.

Which of the following scenarios is most structurally analogous to the capital-expenditure substitution bias described in the passage?

Cevabı ve açıklamayı göster

Cevap: A software company defers fundamental codebase refactoring to prioritize new user-facing features favored by investors, using emergency patches during minor glitches until routine user traffic triggers a total server failure.

Cevap

The scenario in which a software company defers codebase refactoring to build user-facing features, relies on emergency patches, and eventually suffers a total server failure under normal traffic conditions.
The correct option captures the exact functional structure of capital-expenditure substitution bias: external evaluation metrics (investor demands) incentivize visible expansion (new user features) over critical backend upkeep (code refactoring). This leads to temporary containment of minor failures (emergency bug patches) until routine operational stress (standard user traffic) triggers systemic failure.

Adım Adım Çözüm

1
Abstract the core functional mechanism from the passage.
The mechanism involves: (1) an incentive structure that rewards visible expansion over routine core maintenance, (2) hidden degradation of existing core systems, (3) temporary emergency patching of minor symptoms, and (4) ultimate catastrophic collapse triggered by routine operational demands.
Mapping the abstract structural relationships allows for accurate transfer to a novel domain.
2
Evaluate candidate scenarios against all structural components of the abstracted concept.
The scenario involving software development mirrors all four structural components: investor preferences drive visible feature expansion, core codebase maintenance is deferred, minor glitches are patched temporarily, and normal user load causes catastrophic failure.
An accurate parallel scenario must match the systemic cause, management incentives, intermediate coping mechanism, and final outcome.

Which of the following is an assumption on which the management's argument depends?

Cevabı ve açıklamayı göster

Cevap: The expenses involved in maintaining continuous flow equipment will not equal or exceed the cost savings gained from eliminating vessel sterilisation and re-validation downtime.

Cevap

The argument relies on the assumption that the expenses involved in maintaining continuous flow equipment will not equal or exceed the cost savings gained from eliminating sterilisation and re-validation downtime.
The author concludes that transitioning to continuous flow manufacturing will reduce unit production costs by at least 20 percent based on eliminating cleaning and re-validation downtime. For this conclusion to hold, the financial benefit of eliminating downtime must not be neutralized by new costs inherent to continuous flow manufacturing. If maintenance or operational expenses specific to continuous flow equipment equal or exceed the savings gained from eliminating downtime, the overall cost per unit will not fall by 20 percent. Therefore, the assumption that continuous flow maintenance costs will not offset downtime savings is necessary for the conclusion to stand.

Adım Adım Çözüm

1
Identify the premise and conclusion of the argument.
Premise: Continuous flow manufacturing eliminates multi-day downtime needed for vessel cleaning and re-validation between batches. Conclusion: Transitioning to continuous flow manufacturing will reduce overall unit production costs by at least 20 percent.
Deconstructing the argument isolates the evidence from the primary claim.
2
Identify the logical leap between premise and conclusion.
The argument assumes that eliminating downtime savings directly translates to net cost reductions without introducing offsetting expenses.
Gross savings in one operational area only yield net savings if new costs elsewhere do not absorb those savings.
3
Apply the Negation Test to evaluate candidate assumptions.
Negating the statement regarding maintenance costs reveals that if continuous flow maintenance costs equal or exceed downtime savings, unit costs cannot drop by 20 percent. The argument collapses.
A required assumption must shatter the conclusion when logically negated.

Consider the following argument regarding marine conservation policies:

Marine biologist: 'Proponents of establishing large-scale marine protected areas (MPAs) argue that prohibiting commercial fishing within these reserves allows depleted fish populations to recover. However, some local fishing cooperatives contend that MPAs simply displace fishing effort to adjacent unprotected waters, intensifying overfishing outside the reserve boundaries. Nevertheless, recent empirical data from multi-decade MPAs demonstrate that the spillover effect—where mature fish migrate out of the protected zone into surrounding waters—substantially increases total fish biomass and catch yield in adjacent areas over the long term. Therefore, the implementation of well-enforced MPAs ultimately benefits both conservation goals and local fishing economies.'

Management consultant: Many corporate boards have recently mandated that IT departments adopt continuous automated cybersecurity audits to reduce data breach risks. However, installing continuous auditing software requires exposing internal system logs to third-party cloud vendors, creating secondary security vulnerabilities. Thus, adopting automated continuous auditing is unlikely to achieve a net improvement in overall data security unless companies also implement strict zero-trust encryption for all outbound log streams.

Which of the following best describes the logical relationship between the claim that installing continuous auditing software exposes internal system logs to third-party cloud vendors and the claim that adopting automated continuous auditing is unlikely to achieve a net improvement in overall data security unless zero-trust encryption is implemented?

Cevabı ve açıklamayı göster

Cevap: The first claim functions as a premise that identifies a vulnerability, which supports the second claim by justifying why an additional safeguard is necessary for a net benefit.

Cevap

The statement regarding the exposure of system logs acts as a supporting premise that establishes a specific security flaw, thereby providing the necessary logical support for the conclusion that zero-trust encryption must be added to realize a net security improvement.
The correct answer accurately states that the exposure of system logs functions as a premise describing a security drawback. This drawback justifies the conclusion's assertion that continuous auditing alone will not yield a net improvement unless zero-trust encryption is also used.

Adım Adım Çözüm

1
Analyze the structural role of the first claim.
The claim stating that continuous auditing software requires exposing internal logs to third-party vendors describes a drawback/risk inherent to the software.
Identifying the functional content of the premise is essential before assessing how it relates to subsequent claims.
2
Analyze the structural role of the second claim.
The claim following 'Thus' states that adopting automated auditing will not produce a net security improvement unless zero-trust encryption is implemented, which represents the argument's main conclusion.
Transition words like 'Thus' signal the main assertion or recommendation of the argument.
3
Evaluate the inter-claim relationship.
The exposure of system logs creates a new risk; that new risk explains why simply adopting auditing software is insufficient and why an additional security layer (zero-trust encryption) is required for a net security gain.
Connecting the drawback premise to the conditional recommendation demonstrates how the argument flows logically from evidence to conclusion.

Passage:
In industrial ecology, eco-industrial parks (EIPs) are designed so that the waste products of one facility serve as raw material inputs for another, creating closed-loop systems. A primary challenge in establishing stable EIPs lies in the contractual alignment between co-dependent firms. While traditional bilateral supply contracts rely on flexible delivery schedules and market-indexed pricing to cushion external demand shocks, inter-firm byproduct exchanges require rigid physical synchronicity: if a primary manufacturing facility halts production due to a market downturn, its adjacent downstream recipient immediately loses its primary thermal energy or feedstock source.

To mitigate this vulnerability, early EIP designs favored anchoring networks around large, highly stable anchor tenants—typically municipal utility plants or petroleum refineries—whose continuous operations guaranteed an uninterrupted supply of waste heat and chemical byproducts. However, recent economic analyses demonstrate that over-reliance on a single anchor tenant creates a systemic vulnerability known as 'monopsonistic inertia.' If the anchor tenant restructures, upgrades to a zero-waste technology, or faces regulatory curtailment, all secondary facilities tied to its waste stream suffer severe operational disruptions. Consequently, modern EIP frameworks increasingly advocate for multi-node modular networks, wherein secondary facilities maintain auxiliary, secondary connections to regional utility grids, even though operating these backup systems incurs higher baseline overhead costs.

Based on the passage, which of the following can be logically inferred regarding secondary facilities operating within modern multi-node modular eco-industrial parks?

Cevap: They incur higher baseline operating expenses than they would if they relied exclusively on a primary anchor tenant's byproduct stream.

Cevap

Secondary facilities operating in modern multi-node modular networks incur higher baseline operating expenses than they would if they relied exclusively on a primary anchor tenant's byproduct stream.
The passage states that modern multi-node modular networks involve secondary facilities maintaining auxiliary grid connections as backup systems, and explicitly confirms that 'operating these backup systems incurs higher baseline overhead costs.' It directly follows that facilities maintaining these backup systems incur higher baseline operating expenses than they would if relying solely on an anchor tenant without such backup systems.

Adım Adım Çözüm

1
Identify the premises regarding modern multi-node modular networks in the passage.
The final paragraph notes that modern EIP frameworks advocate for multi-node modular networks where secondary facilities maintain auxiliary connections to regional utility grids.
Understanding the specific operational features of modern multi-node modular networks is necessary to evaluate the options.
2
Analyze the stated economic consequence of maintaining these auxiliary connections.
The passage explicitly states that 'operating these backup systems incurs higher baseline overhead costs.'
Direct premise statements dictate what logically must be true about the overhead expenses of facilities with backup systems.
3
Deduce the logical inference.
Because operating auxiliary backup systems adds baseline overhead costs compared to relying solely on a primary anchor tenant without backup systems, operating within the modern framework increases baseline operating expenses.

Consider the following argument: A deep-sea oceanographic research institute plans to replace its fleet of battery-powered autonomous gliders with thermal-gradient gliders for long-term polar climate monitoring. The battery-powered gliders require frequent, expensive ship-based retrieval trips to replace depleted batteries. Because thermal-gradient gliders harvest energy from oceanic temperature differences, they can remain deployed indefinitely, thereby eliminating retrieval trips. The institute concludes that this transition will significantly lower its total operating cost per oceanographic data point collected over a five-year period.

Statement: For the institute's conclusion to hold, it must be assumed that the capital and maintenance costs unique to operating thermal-gradient gliders over five years will not exceed the financial savings achieved by eliminating ship-based battery replacement trips.

Cevabı ve açıklamayı göster

Cevap: True

Cevap

True. The claim represents a necessary unstated assumption because if the unique capital and maintenance costs of thermal-gradient gliders exceed the savings from eliminated ship trips, the overall operating cost per data point over five years will not decrease.
The statement is correct (True) because an argument concluding that overall cost will decrease after eliminating one expense implicitly relies on the assumption that no new expenses equal to or greater than the savings will be introduced. Applying the Negation Test confirms that if new costs exceed saved costs, the conclusion fails.

Adım Adım Çözüm

1
Deconstruct the core argument components.
Premise: Battery replacement requires costly ship trips. Premise: Thermal gliders eliminate ship trips by harvesting oceanic energy. Conclusion: Transitioning to thermal gliders will reduce total operating cost per data point over five years.
Isolating the premise-to-conclusion link clarifies the gap between eliminating one specific expense and reducing overall cost.
2
Identify the logical shift or gap.
The premises show a reduction in ship retrieval expenses, but the conclusion makes a broad claim about total operating cost over a five-year timeframe.
Total cost includes all expenses (capital acquisition, maintenance, payload integration), not just retrieval logistics.
3
Apply the Negation Test to the statement.
Negated statement: The capital and maintenance costs unique to thermal-gradient gliders DO exceed the savings from eliminating ship trips.
Testing the logical contradiction determines whether the assumption is strictly necessary.
4
Evaluate the impact of the negated statement on the conclusion.
If extra equipment costs outweigh retrieval savings, the total operating cost per data point will increase or stay equal, completely invalidating the institute's conclusion.
Since negating the statement breaks the argument, the statement is a required unstated assumption.

Passage:
In mid-nineteenth-century Europe, two contrasting philosophies dominated the restoration of medieval architecture. Eugène Viollet-le-Duc advocated 'stylistic restoration,' arguing that restoring a building meant not merely repairing it, but reinstating it to a state of ideal completeness that might never actually have existed at any given time. To achieve this aesthetic unity, Viollet-le-Duc frequently replaced damaged original features with newly crafted elements designed in what he deemed the building’s purest historical style, sometimes removing authentic additions made during later centuries.

Conversely, British critic John Ruskin and his follower William Morris rejected stylistic restoration as a destructive falsification of history. Ruskin asserted that a building’s historical integrity resided precisely in the cumulative physical traces of time, including wear, decay, and subsequent alterations. Rather than attempting to recreate an idealized past, Ruskin argued for minimal intervention, advocating continuous physical maintenance to arrest decay while preserving all existing historic fabric intact.

Although Viollet-le-Duc’s approach gained initial popularity across continental Europe for creating visually cohesive monuments, it later faced harsh criticism for erasing genuine historical evidence. Critics noted that by stripping away post-medieval modifications, stylistic restorers created synthetic historical constructs that reflected nineteenth-century romanticized ideals rather than authentic medieval craftsmanship. Nevertheless, Viollet-le-Duc’s rigorous structural documentation of Gothic monuments provided foundational techniques that modern architectural conservationists still utilize today.

According to the passage, all of the following were characteristic of Eugène Viollet-le-Duc’s approach to architectural restoration EXCEPT:

Cevap: the prioritization of minimal intervention and continuous physical maintenance over stylistic replacement

Cevap

The option stating that Viollet-le-Duc prioritized minimal intervention and continuous physical maintenance over stylistic replacement is correct because this approach was championed by John Ruskin, whereas Viollet-le-Duc advocated for stylistic restoration.
The passage attributes the philosophy of minimal intervention and continuous physical maintenance specifically to British critic John Ruskin in the second paragraph. Viollet-le-Duc, by contrast, advocated for active stylistic restoration and replacement of building elements. Therefore, this option is NOT true of Viollet-le-Duc's approach and is the correct answer to the EXCEPT question.

An urban planning board evaluated a two-year trial of intelligent adaptive street lighting across 50 municipal districts. Districts equipped with the adaptive lighting recorded a 30% reduction in electrical power consumption and a concurrent 15% decrease in nighttime pedestrian accidents. Critics of the initiative argue that the reduction in pedestrian accidents was not caused by the improved visibility from adaptive lighting, but rather by a simultaneous increase in police foot patrols deployed in those same districts during the trial period.

Which of the following joint selections correctly pairs one statement that, if true, most strongly supports the critics' argument with one statement that, if true, most strongly weakens the critics' argument?

Cevap: Supports Critics: Nighttime pedestrian accidents decreased exclusively during hours when police foot patrols were actively present on the streets. | Weakens Critics: Districts that received an identical increase in police foot patrols but no adaptive lighting upgrades saw no reduction in nighttime pedestrian accidents.

Cevap

The option selecting 'Supports Critics: Nighttime pedestrian accidents decreased exclusively during hours when police foot patrols were actively present on the streets' paired with 'Weakens Critics: Districts that received an identical increase in police foot patrols but no adaptive lighting upgrades saw no reduction in nighttime pedestrian accidents.'
The correct answer provides a valid supporting statement and a valid weakening statement for the critics' argument. The statement indicating that accidents dropped exclusively during active patrol hours strengthens the claim that patrols were responsible for the drop. The statement showing that control districts with increased patrols but no new lighting saw no accident reduction isolates the patrol variable, demonstrating that patrols alone did not cause the decrease and thereby weakening the critics' argument.

Adım Adım Çözüm

1
Analyze the critics' causal argument
Critics claim that Increased Police Foot Patrols → Lower Pedestrian Accidents (and that Adaptive Lighting is not the true cause).
To support the critics, a statement must show that police patrols are directly tied to the accident decline. To weaken the critics, a statement must show police patrols did not cause the decline (or that lighting did).
2
Evaluate candidate statements for supporting the critics
The statement asserting that accidents dropped exclusively during active patrol hours ties the effect strictly to police presence, strongly supporting the critics' claim.
Showing tight temporal concurrency between the candidate cause and the effect strengthens a causal link.
3
Evaluate candidate statements for weakening the critics
The statement showing that control districts with increased patrols but no lighting upgrades experienced no accident reduction isolates the police variable and demonstrates it was insufficient to cause the effect.
If the proposed cause (patrols) occurs without the effect (accident reduction) in control settings, the causal hypothesis is weakened.

Passage:
In strategic management, the concept of "preemptive capability redundancy" describes a defensive framework wherein established enterprise firms intentionally construct and maintain duplicate, non-core operational capacities. Rather than aiming to enhance immediate operational efficiency or expand product lines, the primary objective of this strategy is to systematically monopolize specialized external inputs—such as niche engineering talent, specialized hardware, or proprietary logistical channels—thereby erecting high entry barriers that prevent emerging rivals from securing the resources necessary to scale. By absorbing surplus capacity in adjacent technical domains, the incumbent firm effectively neutralizes potential market threats before competitors can establish an operational foothold.

However, organizational theorists emphasize that this insulation comes at a significant structural cost. Because these auxiliary capacities are maintained primarily for competitive foreclosure rather than active commercial output, they inevitably consume substantial capital reserves and management attention while yielding negligible direct returns. Over time, this dynamic generates severe structural inertia. When the broader industry subsequently encounters a disruptive technological pivot—one that renders both traditional core operations and the stockpiled auxiliary assets obsolete—firms encumbered by preemptive redundancy demonstrate far less agility than leaner, unencumbered market entrants. Consequently, the defensive apparatus explicitly engineered to shield the firm from external rivalry ultimately undermines its internal capacity to pivot toward genuinely novel innovations.

Based on the passage, which of the following scenarios is most structurally analogous to the mechanism and long-term consequence of preemptive capability redundancy?

Cevap: A real estate developer purchases adjacent parcels of land that it does not intend to build on, solely to prevent competing firms from constructing rival commercial complexes. While this preserves the developer's local retail dominance in the short term, ongoing holding costs deplete its reserves, leaving it unable to redevelop its core shopping center when consumer habits shift toward online retail.

Cevap

The scenario involving a real estate developer purchasing adjacent land strictly to block competitors, which subsequently leads to capital depletion and an inability to adapt to online retail trends, is most structurally analogous.
The correct answer accurately maps both stages of the passage concept: (1) acquiring non-essential assets (undeveloped land parcels) strictly to deny inputs/space to potential competitors rather than for immediate productive use, and (2) suffering structural inertia and resource depletion (holding costs) that leave the organization unable to pivot when an external market disruption (shift to online retail) occurs.

1
Identify the core mechanism described in the passage.
An entity acquires or maintains excess, non-core capacity not for productive output, but to lock up critical inputs and prevent rivals from scaling.
Establishing the functional intent of the action is required to match parallel scenarios.
2
Identify the core long-term consequence described in the passage.
The auxiliary capacity drains resources without yielding revenue, creating structural inertia that prevents the entity from pivoting when a major external shift occurs.
The analogy must reflect both the strategic cause and the ultimate negative operational outcome.
3
Evaluate the options for parallel structural alignment across both mechanism and consequence.
The real estate developer scenario mirrors both elements: holding unneeded land parcels to block rival developments (mechanism) and incurring holding costs that prevent pivoting when online retail disrupts the market (consequence).
A valid GMAT RC analogy must match the underlying logical framework rather than surface subject matter.
