Only candidates with a significant background in international relations were considered for the ambassadorial position. Ms. Vance was considered for the position. Thus, it is certain that Ms. Vance is fluent in at least three languages.
Several of the medieval manuscripts found in the northern monastery feature a unique dialect. This specific dialect was not written by any scribe native to the northern province. Hence, some of the manuscripts found in the northern monastery must have been transported there from outside the province.
If the regulatory bill passes, the cost of raw materials will rise. If the cost of raw materials rises, smaller production firms will be compelled to merge. Consequently, if the regulatory bill passes, there will inevitably be a subsequent drop in the sector's innovation metrics.

Cevap

The correct matches pair the ambassadorial argument with the rule connecting international background to fluency, the manuscript argument with the rule about non-native dialects implying outside transportation, and the regulatory bill argument with the rule linking firm mergers to innovation drops.
Each correct pair successfully identifies the unstated premise that mathematically guarantees the truth of the conclusion when added to the existing premises. The ambassadorial argument requires a direct link from background to fluency. The manuscript argument requires a universal rule linking non-native origins to outside transportation. The regulatory argument requires the final link in a conditional chain from merging to an innovation drop.

Adım Adım Çözüm

1
Analyze the ambassadorial argument (Argument 1).
Premises: Vance was considered, and considered candidates have an international relations background. Conclusion: Vance is fluent in three languages.
To identify the deductive gap, which is the missing link between 'international relations background' and 'fluency in three languages'.
2
Match the logical gap for Argument 1.
The assumption 'All persons possessing a significant background in international relations are fluent in at least three languages' correctly bridges this gap.
It acts as the universal sufficient condition to logically guarantee the conclusion about Ms. Vance.
3
Analyze the manuscript argument (Argument 2).
Premises: Manuscripts feature a dialect not written by native scribes. Conclusion: Manuscripts were transported from outside the province.
To identify the deductive gap, which is the rule stating that possessing non-native dialects implies the document was transported from outside.
4
Match the logical gap for Argument 2.
The assumption 'Any document featuring a dialect not written by native scribes of a given region must have been transported there from outside that region' provides the required universal rule.
It perfectly bridges the premise's facts to the conclusion's categorical claim.
5
Analyze the regulatory bill argument (Argument 3).
Premises form a chain: Bill passes -> Costs rise -> Firms merge. Conclusion: Bill passes -> Innovation drops.
To isolate the missing final link in the logical chain, which is 'Firms merge -> Innovation drops'.
6
Match the logical gap for Argument 3.
The assumption 'Whenever smaller production firms are compelled to merge, there is a subsequent drop in the sector's innovation metrics' supplies the missing link.
It completes the conditional chain, mathematically guaranteeing the conclusion.

The streaming service should not cancel the sci-fi series after its first season. Admittedly, the show's viewership numbers are far below the threshold typically required for renewal, and production costs are exorbitant. But the series has cultivated a small, intensely loyal fanbase that would likely cancel their subscriptions if the show is axed.

Cevabı ve açıklamayı göster

Cevap

The solar farm subsidy scenario pairs with the principle on allocating public funds; the honorary degree scenario pairs with the principle on withdrawing prestige; the infrastructure bill scenario pairs with the principle on blocking legislation; and the streaming service scenario pairs with the principle on sustaining an unprofitable product line.
Each scenario presents an argument with a logical gap between its premises and its normative conclusion. To justify each conclusion, a universal principle must establish a sufficient formal condition that guarantees the outcome based strictly on the provided premises. The correct pairings align the specific factual situations with highly abstract conditional rules that logically demand those precise outcomes.

Adım Adım Çözüm

1
Deconstruct the solar farm argument to isolate the logical gap.
The premises state there are no local economic benefits, leading to the conclusion that the subsidy is unjustified. The required principle must connect a lack of local economic benefit to an illegitimate action.
Identifying the exact premise-to-conclusion flow is necessary before evaluating abstract principles.
2
Evaluate the principles to find a sufficient condition for the solar farm argument.
The principle stating that allocating public funds is illegitimate 'unless it provides tangible financial or occupational advantages' matches perfectly.
The 'unless' formulation means that if the advantages are NOT present, the allocation MUST be illegitimate, logically guaranteeing the conclusion.
3
Analyze the honorary degree and streaming service arguments.
The degree argument requires a rule that attacking an expert permits revoking an honor. The streaming argument requires a rule that causing loyal patrons to leave forbids cancellation.
Determining the directionality of the required rules prevents falling for illegal reversals.
4
Match the remaining arguments to their respective highly abstract principles.
The degree argument matches the rule on withdrawing a 'symbol of prestige' due to attacks on a 'professional reputation.' The streaming argument matches the rule on sustaining an 'unprofitable product line' to avoid losing a 'minority of consumers.' The infrastructure bill matches the rule on a leader blocking a 'legislative package.'
Mapping the specific vocabulary of the scenarios to the generalized categorical terms of the principles confirms the structural alignment.

The correct pairings link each specific scenario to the broad conditional rule that connects its premises directly to its conclusion, ensuring the conclusion logically follows.
Each correct pair successfully provides a sufficient bridging principle. A 'justify the conclusion' question requires a rule that, when added to the premises, makes the conclusion 100% valid. The matched principles act as universal rules that logically guarantee the specific conclusions drawn in their respective scenarios.

Eşleşmeler

Cevabı ve açıklamayı göster

Cevap

The open-plan office argument matches the correlation/causation flaw; the zoning regulation argument matches the sufficient/necessary flaw; the campaign promise argument matches the equivocation flaw; and the beverage market share argument matches the proportion/quantity flaw.
Each flawed argument exhibits a classic LSAT logical vulnerability. The open-plan office argument commits a causal flaw. The zoning law argument commits a conditional logic flaw. The political promise argument equivocates on a word's meaning. The beverage company argument confuses percentages with absolute numbers.

Adım Adım Çözüm

1
Analyze the first argument regarding open-plan offices.
Identifies that a simultaneous occurrence (open plans and increased productivity) is used to claim a direct cause.
This aligns with the classic flaw of confusing correlation with causation.
2
Analyze the second argument regarding building approval.
Identifies conditional logic where 'designed by architect (sufficient) -> approved' is reversed to 'approved -> designed by architect (necessary)'.
This represents treating a sufficient condition as a necessary one, an illegal reversal.
3
Analyze the third argument regarding political transparency.
Identifies that 'transparency' means political openness in the premise, but physical see-through material in the conclusion.
This matches the definition of equivocation, or shifting the meaning of a key term.
4
Analyze the fourth argument regarding market share.
Identifies that market share (a percentage) does not guarantee absolute sales volume (a number), since the total market size could have shrunk.
This demonstrates the flaw of confusing proportions with absolute quantities.

Cevap

The utilitarian argument pairs with the legislation failing to maximize happiness. The avian argument pairs with the ground-weaver bird nesting on the ground. The startup argument pairs with NovaTech lacking consistent growth. The artifact argument pairs with the shield not being forged before the collapse.
Each correct match successfully bridges the logical gap between the argument's premises and its conclusion. By formally linking the 'rogue' subject introduced in the conclusion to the conditional rules provided in the premises, the assumptions validate the inferences (often by satisfying the sufficient condition or triggering the contrapositive).

Adım Adım Çözüm

1
Analyze the formal logic of each argument's premise to identify sufficient and necessary conditions.
Identified conditional rules such as 'Morally Justified → Maximizes Happiness' and 'Nests on Ground → Susceptible to Predation'.
Supporter assumptions often rely on completing conditional chains or triggering contrapositives.
2
Examine the conclusion of each argument to determine what new element has been introduced.
Identified specific subjects in the conclusions: 'healthcare legislation', 'ground-weaver bird', 'NovaTech', and 'copper shield'.
The new subject in the conclusion must be explicitly linked to the rule established in the premise.
3
Formulate the missing link (supporter assumption) that legally connects the new subject to the established conditional rule.
Generated the required bridging statements to validate the argument.
This guarantees the truth of the conclusion based on the premise.

Cevabı ve açıklamayı göster

Cevap

The correct pairings match each specific argument with its corresponding causal flaw: temporal sequence to post hoc, wheelchair use to reversed causality, umbrellas/rainboots to a common third factor, and sugar/weight gain to assuming a sole cause.
Each argument perfectly demonstrates one specific causal fallacy. Matching them requires identifying the structural gap between the evidence provided and the causal conclusion drawn.

Adım Adım Çözüm

1
Analyze the first argument regarding the software update.
Identify that the only evidence provided for causation is that the update happened immediately before the crash.
This matches the flaw of assuming causation based solely on a temporal sequence.
2
Analyze the second argument regarding wheelchair use.
Recognize that physical disability leads to wheelchair use, but the argument claims the opposite.
This represents the flaw of reversing the actual direction of cause and effect.
3
Analyze the third argument regarding umbrellas and rainboots.
Identify that rainy weather causes people to use both umbrellas and rainboots.
This matches the flaw of ignoring a common third factor that causes both phenomena.
4
Analyze the fourth argument regarding sugar and weight gain.
Note that while sugar causes weight gain, other factors can also cause weight gain.
This demonstrates the flaw of treating one possible cause as the only possible cause.

Cevap

The correct pairings successfully map the specific factual premises of each argument to a generalized, abstract rule that functions as a sufficient assumption, conclusively guaranteeing the stated conclusion.
Each abstract principle functions as a perfect sufficient bridge. By substituting the concrete terms from the scenarios (e.g., 'CEO', 'wind shear', 'tariff') into the abstract logical variables of the corresponding principles (e.g., 'leadership capacity', 'unforeseeable environmental anomalies', 'economic directive'), the arguments are transformed into valid deductive syllogisms.

Adım Adım Çözüm

1
Analyze the Corporate Argument
Identify the gap: Action boosted share prices but depleted cash reserves -> Must terminate CEO. Match with the Fiduciary principle.
The Fiduciary principle provides the exact conditional rule needed: If you compromise foundational security (reserves) for transient enhancement (stock spike), you must be relieved of leadership (terminated).
2
Analyze the Drone Argument
Identify the gap: Compliant algorithms + unpredictable wind shear -> Manufacturer blameless. Match with the Liability principle.
The Liability principle formally establishes that functioning within guidelines (compliant algorithms) + unforeseeable environmental anomalies (wind shear) equates to no culpability (blameless).
3
Analyze the Ethics Argument
Identify the gap: Deceptive techniques used + groundbreaking insights gained -> Must sanction. Match with the Ethical Breach principle.
The Ethical Breach principle mandates penalties for ethical breaches (deception) regardless of the magnitude of benefits (groundbreaking insights).
4
Analyze the Tariff Argument
Identify the gap: Protects local jobs + increases construction costs -> Sound economic policy. Match with the Economic principle.
The Economic principle explicitly states that preventing domestic employment loss justifies a directive, even if it escalates material expenses.

Mayor matches with the port modernization; Transit Advocate matches with tradespeople needing vehicles; Financial Advisor matches with asset liquidation differences; Environmental Critic matches with municipal boundary expansion.
Each correct pairing links a specific logical flaw in the speaker's argument to a factual statement that perfectly exploits that gap. The Mayor's causal flaw is attacked by an alternate cause (the port). The Transit Advocate's assumption of feasibility is attacked by a practical barrier (need to haul equipment). The Financial Advisor's equivocation is attacked by separating failure rate from financial loss magnitude. The Environmental Critic's use of raw numbers is attacked by shifting the baseline population.

1
Analyze the Mayor's argument.
Identified a causal claim: Tax abatements caused the drop in vacancy rates.
To find the weak point, which in causal arguments is often an alternate explanation for the observed effect.
2
Match the Mayor's argument to a weakening statement.
Matched with the port modernization statement.
The port modernization provides a compelling alternate cause for the industrial real estate boom, directly undermining the conclusion that tax abatements were responsible.
3

Identified a practical assumption: The 40,000 drivers can and will switch to the new bus lane.
To weaken a proposed solution, one must show why it is unfeasible or why the intended users cannot adopt it.
4
Match the Transit Advocate's argument to a weakening statement.
Matched with the tradespeople statement.
If 80% of the drivers require their vehicles for bulky equipment, they cannot switch to a bus, rendering the proposed solution ineffective.
5
Analyze the Financial Advisor's argument.
Identified a gap in terminology: Equating failure rate with total financial exposure.
To weaken arguments that shift terms between the premise and conclusion, find evidence that distinguishes the two concepts.
6
Match the Financial Advisor's argument to a weakening statement.
Matched with the asset liquidation statement.
This shows that a higher failure rate does not equate to higher financial exposure, as tech failures allow for capital recovery while hospitality failures do not.
7
Analyze the Environmental Critic's argument.
Identified a numbers vs. proportions flaw: Using a total volume increase to claim a per-capita efficiency program failed.
To weaken claims relying on total raw numbers to judge a rate or proportion, find a factor that skews the baseline, such as population growth.
8
Match the Environmental Critic's argument to a weakening statement.
Matched with the municipal boundaries statement.
A 20% population increase easily accounts for a 5% increase in total waste, indicating the per-capita waste actually decreased, meaning the ban likely succeeded.

The correct pairings connect each argument's specific premise to its novel conclusion: the archaeology argument pairs with the assumption about native individuals and strontium; the economics argument pairs with the job stimulation assumption; the biology argument pairs with the marmot hibernation assumption; and the ethics argument pairs with the assumption about personal recognition.
Each correct assumption functions as a deductive bridge. By connecting the disconnected terminology in the premise to the novel terminology introduced in the conclusion, the assumption closes the logical gap and allows the argument's inference to be validly drawn.

Adım Adım Çözüm

1
Analyze each stimulus to identify the premise and the conclusion.
Isolated the evidence provided and the final claim made for each argument.
Understanding the structure of the argument is necessary to spot the logical gap.
2
Identify the 'rogue' terms in each argument's conclusion.
Found new concepts in the conclusions (e.g., 'moral justification', 'not born in the local region') that did not appear in the premises.
Supporter assumptions must bridge the logical gap by connecting these rogue terms back to the premise evidence.
3
Match the rogue terms to the assumptions that logically connect them to the premises using formal conditional logic.
Successfully paired each argument with the assumption that guarantees the conclusion when added to the premise.
This validates the argument, fulfilling the definition of a necessary and sufficient supporter assumption.

A recent study found that employees who take frequent short walks during the workday report significantly lower levels of stress. Therefore, to decrease overall employee stress, the corporation should mandate daily short walks for all staff.
The number of traffic accidents involving electric scooters in the city has tripled this year compared to last year. Clearly, riding an electric scooter has become significantly more dangerous for the individual rider.
A survey of readers of 'Peak Athletics' magazine revealed that 80% of respondents prefer plant-based protein supplements over whey protein. Thus, a vast majority of the general athletic population is shifting toward plant-based diets.
The municipal government can either expand the downtown highway system or suffer from continuously worsening traffic congestion. Since expanding the highway would completely exhaust the municipal budget, the city will inevitably suffer from worsening traffic.

Cevap

Argument 1 (stress) matches with the evidence regarding high-pressure project assignments. Argument 2 (scooters) matches with the evidence of the sixfold increase in total miles traveled. Argument 3 (survey) matches with the evidence of subscription bias among plant-based consumers. Argument 4 (traffic) matches with the evidence regarding neighboring municipalities optimizing bus networks.
Each argument contains a distinct, classic logical flaw. The correct counter-evidence directly exploits the specific gap in that argument. The workplace stress argument assumes causality from a correlation, which is weakened by showing reverse causality. The scooter argument confuses absolute numbers with proportional rates, which is weakened by a massive increase in total riders. The magazine survey argument relies on an unrepresentative sample, which is weakened by showing the sample is inherently biased. The traffic argument restricts the possibilities to a false dilemma, which is weakened by demonstrating a successful alternative option.

Adım Adım Çözüm

1
Analyze the workplace stress argument to identify its logical gap.
The argument relies on a correlation-to-causation jump, assuming walks cause reduced stress rather than the reverse.
Identifying the causal flaw directs you to look for evidence that suggests reverse causation or a third variable.
2
Select the evidence that attacks the causal flaw in the stress argument.
The evidence stating highly stressed employees are prohibited from taking breaks perfectly exploits this gap.
It shows that stress levels determine the ability to walk, completely undermining the recommendation to mandate walks to cure stress.
3
Evaluate the electric scooter argument's reasoning.
The argument commits a numbers-to-percentages error, assuming an increase in total accidents means an increase in individual risk (rate).
To weaken a numbers-to-rates argument, you must find evidence altering the baseline or total population.
4
Select the evidence that addresses the baseline for the scooter argument.
The evidence regarding the sixfold increase in total scooter miles directly attacks this flaw.
If use increased 6x but accidents only increased 3x, the danger per rider has actually dropped, destroying the conclusion.
5
Examine the survey argument and the traffic argument.
The survey argument relies on an unrepresentative sample, while the traffic argument relies on a false dilemma (only two options).
Identifying these specific structural flaws makes the remaining matches clear.
6
Match the remaining arguments to their respective weakeners.
The survey argument matches the evidence showing magazine subscribers are disproportionately plant-based (exposing the sample bias). The traffic argument matches the evidence showing bus optimization as a third option (breaking the false dilemma).
Each piece of evidence surgically targets the distinct vulnerability of its paired argument.

Match the university scenario to subgroup aggregation (Simpson's Paradox), the bear encounter scenario to baseline population distribution, the software plug-in scenario to self-selection bias, and the CEO scenario to shifting denominators (fractional share vs. absolute quantity).
Each correct pairing accurately links a specific statistical phenomenon to its underlying structural reality. The university scenario requires recognizing how weighted averages behave across uneven groups. The bear scenario requires understanding how base rates dictate raw outcome volumes. The software scenario requires spotting selection bias in observational data. The executive compensation scenario requires distinguishing relative proportions from absolute figures.

Adım Adım Çözüm

1
Analyze the university admissions paradox.
Identify that a rate can be higher in all subgroups but lower overall only if the group sizes and baseline success rates differ drastically.
This is a classic manifestation of Simpson's Paradox, matched with the resolution describing 'subgroups of disparate sizes'.
2
Evaluate the bear encounter conclusion.
Recognize that comparing raw counts (or percentages of total outcomes) without accounting for the number of people in each area creates a logical flaw.
The resolution must point out the missing 'baseline population distribution'—there are simply more people near trails.
3
Examine the software optimizer correlation.
Identify that the two variables (optimizer use and crashes) are correlated, but the cause and effect are likely reversed due to who chooses to use the software.
The 'self-selection bias' resolution perfectly explains why the affected demographic actively seeks the intervention.
4
Assess the CEO's compensation claim.
Spot the discrepancy between a decreasing percentage (5% to 3%) and an increasing absolute amount.
This requires the structural rule that a smaller fraction of a much larger whole can yield a larger absolute quantity.

Cevap

The correct pairings are: the Sports Physiologist commits a correlation-causation error, the Software Developer makes an ad hominem attack, the Acoustics Engineer commits a composition (part-to-whole) error, and the Chief Financial Officer relies on a false dilemma.
Each argument stimulus perfectly demonstrates a classic logical fallacy. The Sports Physiologist jumps from correlation to causation. The Software Developer attacks the speaker's motives instead of the argument. The Acoustics Engineer applies properties of individual parts to the collective whole. The Chief Financial Officer creates a false dichotomy.

Adım Adım Çözüm

1
Analyze the Sports Physiologist's argument to identify the gap between the premise and conclusion.
The premise is a correlation ('found that athletes who... are significantly less likely'), and the conclusion is causal ('directly prevents'). This maps to the correlation-causation flaw description.
Identifying the shift from association to causation is key to recognizing this archetype.
2
Examine the Software Developer's rebuttal of the lead engineer.
The rebuttal focuses entirely on the engineer's emotional state regarding a promotion, rather than addressing the technical claim about rate limiting. This matches the source/motive attack description.
An ad hominem flaw requires noting when an argument's substance is ignored in favor of attacking the speaker.
3
Evaluate the Acoustics Engineer's reasoning regarding the sound system.
The argument moves from the characteristics of an 'individual acoustic panel' to the 'soundproofing system as a whole'. This perfectly aligns with the composition flaw description.
Structural flaws often involve improper leaps between parts and wholes.
4
Deconstruct the Chief Financial Officer's conclusion.
The CFO sets up an 'either/or' scenario and eliminates one extreme option to force the other. It ignores the possibility of moderate limits, matching the false dilemma description.
When a conclusion depends on a strict binary choice, the flaw usually involves overlooking middle-ground alternatives.

The chef argument matches the necessary/sufficient flaw description; the commuter argument matches the correlation/causation flaw; the architect argument matches the part-to-whole flaw; and the transit system argument matches the equivocation flaw.
Each correct pairing accurately links a specific, flawed argument to its formal abstract logical description. The first argument exhibits a conditional logic flaw by treating a requirement as a guarantee. The second demonstrates a causal flaw by assuming a correlation implies causation. The third shows a fallacy of composition by assuming the firm will inherit the traits of its individual designers. The fourth displays equivocation by using the term 'reliable' in two different ways.

Adım Adım Çözüm

1
Analyze the first argument regarding the master chef to identify its structural flaw.
Identified as confusing a necessary requirement with a sufficient guarantee.
Conditional logic errors are a primary category of logical flaws, often confusing what is required with what is enough.
2
Examine the second argument about commuters and classical music.
Identified as assuming causation from a mere correlation.
Observational studies often present correlated variables that do not necessarily have a direct causal link, as other factors could be involved.
3
Evaluate the third argument concerning the architectural firm.
Identified as inappropriately applying characteristics of individuals to the group they form.
Properties of parts do not automatically transfer to the whole, which is known as the fallacy of composition.
4
Assess the fourth argument about the public transit system.
Identified as shifting the meaning of the word 'reliable' mid-argument.
Logical consistency requires key terms to maintain the exact same definition throughout the premises and conclusion; shifting meanings creates an equivocation flaw.

Cevap

The archives argument pairs with the equivocation flaw; the taxonomy argument pairs with the sufficient-necessary confusion; the quantum processor argument pairs with the composition flaw; and the civic theater argument pairs with the false dilemma.
Each argument exhibits a distinct structural flaw that corresponds to a specific abstract description. The archives argument shifts the meaning of a key term. The taxonomy argument illegitimately reverses a conditional statement. The quantum argument assumes the whole shares the exact property of its parts. The theater argument ignores alternative explanations, presenting a false dichotomy.

Adım Adım Çözüm

1
Analyze the historical archives argument to identify its structural flaw.
The term 'accessible' changes meaning from conceptual availability to physical entry.
Identifying shifted terminology is necessary to match it with the ambiguity/equivocation description.
2
Evaluate the taxonomy argument to determine the logical error in its conditional reasoning.
The argument affirms the necessary condition (central nervous system) to falsely conclude the sufficient conditions (bilateral symmetry).
This reveals a classic illegal reversal, matching the description of confusing necessary and sufficient conditions.
3
Examine the quantum processor argument for flaws relating to the scope of its conclusion.
The argument wrongly attributes the property of the individual parts (qubits) directly to the complex whole (the processor).
This fits the structural definition of a composition flaw.
4
Analyze the civic theater argument to spot the error in its disjunctive conclusion.
The argument ignores other potential causes for the initiative's failure beyond funding and disinterest.
This confirms the presence of an unwarranted assumption that the stated alternatives are exhaustive, which is a false dilemma.
