Consider the following argument:

Urban Planner: Implementing high-density zoning regulations is unequivocally the most effective way to manage population growth in our city. We can be certain of this, because creating policies that mandate concentrated housing developments serves as the optimal strategy for handling urban demographic expansion.

The urban planner's argument is vulnerable to criticism on the grounds that it presupposes the truth of the conclusion it sets out to establish.

Cevabı ve açıklamayı göster

Cevap: True

Cevap

The statement is True.
The argument commits circular reasoning because the premise ('creating policies that mandate concentrated housing developments serves as the optimal strategy for handling urban demographic expansion') is logically identical to the conclusion ('Implementing high-density zoning regulations is unequivocally the most effective way to manage population growth'). Therefore, the statement accurately identifies the flaw.

Adım Adım Çözüm

1
Identify the main conclusion of the argument.
The conclusion is that 'Implementing high-density zoning regulations is unequivocally the most effective way to manage population growth in our city.'
Locating the conclusion is the first step in evaluating any logical flaw.
2
Identify the premises provided to support the conclusion.
The sole premise is that 'creating policies that mandate concentrated housing developments serves as the optimal strategy for handling urban demographic expansion.'
Understanding the evidence is necessary to see how the author attempts to prove the conclusion.
3
Analyze the relationship between the premise and the conclusion.
The phrase 'concentrated housing developments' is a direct definition of 'high-density zoning', and 'handling urban demographic expansion' means 'manage population growth'.
This reveals whether the premise provides independent support or merely repeats the conclusion.
4
Determine the nature of the logical flaw.
Because the premise simply restates the conclusion using synonymous terms without providing outside evidence, the argument commits circular reasoning.
Evaluating the structural relationship confirms that the argument presupposes what it sets out to prove.

Anahtar Kavram

Circular reasoning (begging the question) occurs when an argument's premise is substantially the same as its conclusion, offering no independent evidence to support the claim.

Cevap

Farm automation matches with the third variable flaw; frog coloration matches with reverse causation; solar panels and bird decline matches with coincidental trends; and back braces match with mitigating a pre-existing condition.
Each argument commits a specific variation of the correlation-causation fallacy. The agricultural argument overlooks an external third variable. The frog argument reverses the likely biological cause and effect. The bird argument forces a link between independent timelines. The back brace argument confuses a treatment for a condition with the cause of that condition.

Linguistic anthropologists analyzing digital communication trends found that online forums with the highest frequency of newly coined vocabulary also exhibit the lowest rates of user retention over a five-year period. The anthropologists conclude that the continuous introduction of novel terminology alienates casual participants, which in turn causes them to abandon these forums.

Which one of the following most accurately describes a flaw in the anthropologists' reasoning?

Cevabı ve açıklamayı göster

Cevap: It fails to exclude the possibility that a single independent factor is causally responsible for both of the phenomena that the anthropologists observed.

Cevap

The correct answer is the option stating that the argument fails to exclude the possibility that a single independent factor is causally responsible for both observed phenomena.
The argument observes a correlation between Phenomenon A (new vocabulary) and Phenomenon B (low user retention) and assumes that A causes B. The correct answer points out a classic flaw in this reasoning: it ignores the possibility that a third, underlying factor (such as the forums being dedicated to highly volatile, short-lived trends) might independently cause both the rapid generation of slang and the rapid departure of users.

Adım Adım Çözüm

1
Identify the argument's premises.
Premise: There is a correlation between high frequency of new vocabulary and low rates of user retention.
Deconstructing the argument is the first step to evaluating its logical soundness.
2
Identify the argument's main conclusion.
Conclusion: The introduction of novel terminology causes users to abandon the forums.
Understanding exactly what the author is trying to prove reveals the logical leap.
3
Evaluate the logical gap between the premise and conclusion.
The author moves directly from a statistical correlation to a definitive causal relationship (A causes B).
Whenever an author assumes causation from correlation, the argument is vulnerable to alternative explanations.
4
Anticipate the standard alternative explanations for causal flaws.
The correlation could be caused by reverse causality (B causes A), coincidence, or a third common variable (C causes both A and B).
Pre-phrasing the flaw helps bypass intentionally confusing language in the answer choices.
5
Evaluate the options against the anticipated flaws.
The correct option abstractly describes the 'third variable' flaw, pointing out that an independent factor could cause both the new vocabulary and the low retention.
This precisely identifies a glaring logical vulnerability in the author's reasoning.

Cevap

The Literary Critic commits synonymic paraphrasing, the HR Director relies on a relational evidentiary loop, and the Sociologist uses definitional circularity.
Each argument represents a distinct archetype of begging the question. The Literary Critic uses synonymic circularity (repeating the conclusion using different words). The HR Director uses relational loop circularity (the evidence requires the conclusion to be true to be considered valid evidence). The Sociologist uses definitional circularity (using a definition to prove a substantive claim).

Adım Adım Çözüm

1
Analyze the Literary Critic's argument to identify the relationship between the premise and conclusion.
The argument uses the premise of 'intricately layered and sophisticated storytelling' to prove 'narrative complexity'.
This reveals that the premise and conclusion are identical in meaning, which points to synonymic paraphrasing.
2
Analyze the HR Director's argument to evaluate the source of credibility.
The argument trusts the protocol because top analysts made it, but trusts those analysts because the protocol identified them.
This establishes an evidentiary loop where the proof relies on the conclusion being true.
3
Analyze the Sociologist's argument regarding the requirements for a prosperous community.
The argument claims civic engagement is necessary because it defines a prosperous community as one with civic engagement.
This identifies definitional circularity, where a conclusion is guaranteed merely by the definition of terms.

Botanist: A recent survey of the Blackwood Forest revealed a consistent pattern regarding the Xanthoria lichen. Specifically, the areas of the forest with the highest concentration of this lichen on tree trunks are precisely the areas where the average pine tree bark is substantially thicker than in the rest of the forest. Therefore, it is clear that the presence of Xanthoria lichen stimulates the pine trees to produce thicker layers of bark as a protective response.

Which one of the following most accurately describes a flaw in the botanist's reasoning?

Cevabı ve açıklamayı göster

Cevap: It overlooks the possibility that trees possessing naturally thicker bark offer a more hospitable surface, which in turn encourages the heavy growth of the lichen.

Cevap

The argument overlooks the possibility that trees possessing naturally thicker bark offer a more hospitable surface, which in turn encourages the heavy growth of the lichen.
The correct answer accurately diagnoses the classic correlation-to-causation fallacy present in the stimulus. The botanist observes that two phenomena occur together (thick bark and lichen density) and hastily concludes that the lichen causes the thick bark. The correct answer highlights the possibility of reverse causality: the thick bark might actually be the cause of the dense lichen growth.

Adım Adım Çözüm

1
Analyze the structure of the argument.
Premise: High lichen concentration correlates with thicker tree bark. Conclusion: Lichen causes the trees to produce thicker bark.
Identifying the premise and the conclusion is required to evaluate the validity of the reasoning.
2
Identify the logical flaw connecting the premise to the conclusion.
The argument moves from a simple correlation to a definitive causal relationship (A causes B).
Recognizing this jump highlights the classic 'Correlation vs. Causation' flaw.
3
Determine alternative explanations for the correlation.
It is entirely possible that B causes A (reverse causality): the thicker bark might be the very reason the lichen is able to grow so densely in those areas.
Finding alternative explanations demonstrates why the author's strict causal conclusion is unwarranted.
4
Select the option that best describes this specific causal flaw.
The correct option points out the reverse causality scenario, exposing the vulnerability in the botanist's reasoning.

Urban Planner: To remain viable amidst shifting global climates, major coastal cities must undergo immediate and extensive adaptation. However, evolutionary biologists have conclusively demonstrated that genuine adaptation cannot be rushed; it is a gradual process requiring hundreds of generations of natural selection. Consequently, our coastal cities cannot realistically remain viable.

Which one of the following most accurately describes a flaw in the urban planner's argument?

Cevabı ve açıklamayı göster

Cevap: It relies on two distinct and incompatible meanings of the word 'adaptation'.

Cevap

The argument is flawed because it relies on two distinct and incompatible meanings of the word 'adaptation'.
The correct answer accurately identifies the fallacy of equivocation. The argument hinges on the word 'adaptation.' In the opening sentence, 'adaptation' means conscious, structural modifications (e.g., building seawalls). In the second sentence, 'adaptation' means the biological evolution of species through natural selection. By treating these two distinct concepts as identical, the argument draws an invalid conclusion.

Adım Adım Çözüm

1
Analyze the urban planner's first premise.
The planner states that coastal cities need 'adaptation' to survive climate shifts.
Understanding the context of the first premise reveals that 'adaptation' here refers to deliberate, structural, or policy modifications made by humans to urban environments.
2
Analyze the urban planner's second premise.
The planner states that 'adaptation' requires hundreds of generations of natural selection, according to evolutionary biologists.
Understanding the context of the second premise reveals that 'adaptation' here refers to a purely biological, genetic process occurring in living populations.
3
Evaluate how the premises combine to form the conclusion.
The planner concludes that cities cannot survive because they don't have hundreds of generations to wait.
The conclusion is logically flawed because it illegitimately applies the constraints of biological 'adaptation' to the structural 'adaptation' of a city. This is the fallacy of equivocation.

Cevap: takes for granted that one phenomenon is the cause of another simply because the two phenomena frequently occur together

Cevap

The correct answer identifies that the argument takes for granted that one phenomenon is the cause of another simply because the two phenomena frequently occur together.
The argument's fundamental error is concluding that iridium causes fungal growth merely because the two are found together in the same rock layers. It fails to consider that a third factor (such as a catastrophic event, like an asteroid impact) might have caused both the iridium deposition and an environment full of decaying matter that encouraged fungal growth. The correct answer accurately abstracts this logical flaw.

Adım Adım Çözüm

1
Analyze the premises of the argument.
The premise establishes a strong statistical correlation: high iridium concentrations and vast amounts of fossilized fungal spores are frequently found together in the same sediment layers.
Identifying the foundational evidence is the first step in evaluating the argument's logical structure.
2
Identify the argument's conclusion.
The conclusion claims that the presence of high levels of iridium directly promotes fungal proliferation (a causal relationship).
The conclusion reveals the author's main point and how they interpreted the evidence.
3
Evaluate the logical gap between the premise and the conclusion.
The argument jumps from a mere correlation (things happening together) to a definitive causal claim (one thing causes the other), ignoring alternative explanations such as a third factor causing both phenomena.
Finding the logical leap exposes the core vulnerability or flaw in the reasoning.
4
Select the option that accurately describes this structural gap.
The option stating that the argument assumes causation simply because two phenomena frequently occur together perfectly matches the observed flaw.

A city ordinance dictates that all "essential" businesses must remain open during the public health emergency. Since bookstores are essential to the cultural vitality of any city, they must be required to remain open. Additionally, the ordinance requires "fair" compensation for emergency workers. Because paying everyone exactly the same hourly wage is fair, the city must standardize the pay of all doctors and sanitation workers to the same flat rate.

The argument's reasoning is vulnerable to criticism on which of the following grounds? (Select all that apply)

Geçerli olan tümünü seçin

Cevabı ve açıklamayı göster

Cevap: It illicitly shifts the meaning of "essential" from "crucial for basic safety and infrastructure" to "highly valuable for cultural enrichment."; It relies on two different senses of the word "fair," conflating equitable remuneration for varied work with strictly identical payment amounts.

Cevap

The argument is flawed because it equivocates on two key terms, incorrectly shifting the definitions of both 'essential' and 'fair' midway through its reasoning.
The argument commits two distinct fallacies of equivocation. First, it conflates a practical, emergency-related definition of 'essential' with an abstract, cultural definition. Second, it shifts the meaning of 'fair' from its standard policy context of equitable compensation to a rigid definition of strictly identical pay. Both correct options accurately capture these specific semantic shifts.

Adım Adım Çözüm

1
Analyze the first half of the argument regarding 'essential' businesses.
The ordinance uses 'essential' to mean necessary for surviving an emergency. The author then applies this rule to bookstores because they are 'essential' for cultural vitality.
Identifying semantic shifts requires comparing how a term is used in a premise versus how it is applied to reach the conclusion.
2
Analyze the second half of the argument regarding 'fair' compensation.
The ordinance requires 'fair' (equitable/just) pay for workers. The author concludes this means paying a doctor and a sanitation worker the exact same flat rate.
This highlights a second instance where a generally understood policy term is manipulated into a different literal meaning.
3
Evaluate the answer choices based on the identified semantic shifts.
The choices that describe the changing meanings of 'essential' and 'fair' accurately critique the logical vulnerabilities of the argument.
To correctly answer a Flaw question, the selected choices must describe an error that actually occurred in the text.

Urban Planner: A comprehensive review of our city's districts reveals a clear pattern. The neighborhoods boasting the highest concentration of community-funded street murals consistently experience the lowest rates of property crime. Therefore, to effectively combat property crime in our most vulnerable districts, the city council should allocate significant funding to commission new street murals in those areas.

Which of the following, if true, provides an alternative explanation for the observed correlation that exposes a flaw in the planner's causal reasoning? (Select all that apply)

Cevabı ve açıklamayı göster

Cevap: Neighborhoods with active neighborhood watch programs and strong civic participation are both highly effective at deterring property crime and more likely to successfully organize mural projects.; Community art organizations strongly prefer to initiate and fund street mural projects in neighborhoods that already boast exceptionally low property crime rates to protect their investments.

Cevap

The correct selections are the options indicating that civic participation drives both factors, and that art organizations intentionally choose low-crime areas for murals.
Both correct options successfully weaken the argument by providing alternative explanations for the observed correlation. One introduces a 'third variable'—active civic participation—that independently causes both high mural concentration and low crime rates. The other introduces 'reverse causality', suggesting that low crime rates attract murals, proving that adding murals to a high-crime area would not necessarily lower crime.

Adım Adım Çözüm

1
Identify the argument's core structure.
Premise: Correlation between street murals and low crime rates. Conclusion: Funding street murals will reduce crime.
Deconstructing the argument is necessary to evaluate the relationship between evidence and conclusion.
2
Identify the logical flaw.
The planner assumes a causal relationship (murals cause crime reduction) based solely on an observed correlation.
Recognizing the 'correlation vs. causation' flaw directs the search for alternative explanations.
3
Evaluate options for alternative causal pathways.
Identify options that explain the correlation through a third common cause or reverse causality.
Valid alternative explanations weaken the argument by showing the planner's assumed causal link is not the only reasonable interpretation of the data.

Cevap: fails to consider the possibility that a company's high productivity provides the financial resources and morale necessary to host frequent social events

Cevap

The argument is flawed because it ignores the possibility of reverse causation—that being highly productive causes the firm to host more social events, rather than the social events causing the productivity.
The correct option identifies the classic flaw of assuming causation from correlation. Specifically, it points out the possibility of reverse causality: instead of social events causing high productivity, the high productivity (and resulting financial success) might be the actual cause that allows the firm to afford frequent social events.

Cevap

The correct answer is the option stating that the argument conflates an observed, scientific regularity with a prescriptive rule of conduct.
The correct answer accurately identifies the equivocation flaw. The theorist uses the word 'law' in two entirely different senses: first as a descriptive scientific principle ('laws of physics'), and second as a prescriptive rule ('drafts and enforces'). By conflating these two distinct meanings, the argument falsely concludes that a scientific law inherently requires a conscious creator in the same way a legal statute does.

Adım Adım Çözüm

1
Analyze the argument's premises and main conclusion.
Premise 1: There are laws of physics. Premise 2: A law implies a lawmaker who drafts and enforces it. Conclusion: There must be a conscious lawmaker of the universe.
Deconstructing the argument structure is necessary to isolate how the premises relate to the conclusion.
2
Examine key terms that are repeated or central to bridging the premises to the conclusion.
The central term bridging the premises is 'law' (and 'laws').
Repeated terms are often the site of semantic shifts in flawed reasoning.
3
Determine if the meaning of the key term remains strictly consistent throughout its usages.
It does not. 'Laws of physics' refers to descriptive, observed regularities in nature. 'Drafts and enforces' refers to prescriptive, human-made rules of conduct. The meanings are fundamentally different.
Identifying a shift in meaning reveals an equivocation flaw, invalidating the logical deduction.

Agricultural economists have tracked farming practices across various regions for the past decade. They discovered a strong statistical correlation: regions that most rapidly adopted new drought-resistant crop varieties also experienced the most significant declines in overall soil nutrient levels. The economists concluded that the cultivation of these newly developed drought-resistant crops actively depletes soil nutrients at a much faster rate than the cultivation of traditional crops.

Which of the following statements, if true, provide a valid alternative explanation for the observed correlation? Select all that apply.

Cevap: Severe, prolonged droughts prompted the shift to the new crops in these regions, and these droughts independently cause rapid soil nutrient degradation.; The drought-resistant crop varieties were primarily subsidized and distributed to regions that were already suffering from rapidly deteriorating soil conditions.

Cevap

The correct statements are the one identifying droughts as a common cause for both factors, and the one identifying pre-existing poor soil as the reason for distributing the crops to those regions.
The correct options both successfully provide alternative reasons for why drought-resistant crops and soil nutrient depletion are found together. One introduces a third variable (prolonged droughts cause both the adoption of the crops and the soil degradation). The other introduces a reverse causal relationship (the crops were brought to areas because the soil was already degrading). Both successfully sever the economists' assumed causal link.

Cevap: It bases its conclusion on the ambiguous use of the term 'independent' across different parts of the argument.; It conflates an auditor's lack of financial ties to a company with a personality trait characterized by nonconformity.

Cevap

The correct answers identify that the argument relies on the ambiguous use of the term 'independent', specifically conflating a lack of financial ties with a nonconformist personality.
The argument commits the fallacy of equivocation by using the word 'independent' in two entirely different senses. In the first premise, it means having no financial conflicts of interest. In the second premise, it describes a rebellious or nonconformist personality. The conclusion improperly relies on the second meaning to satisfy the condition established by the first meaning. The correct answers describe this shift both abstractly (ambiguous use) and concretely (conflating financial ties with nonconformity).

Adım Adım Çözüm

1
Analyze the core structure of the financial advisor's argument.
Premise 1 establishes that an 'independent' auditor (defined as having no financial ties) produces an objective analysis. Premise 2 states the new auditor is 'independent' (defined as having a nonconformist personality). The conclusion is that the new auditor will produce an objective analysis.
Breaking the argument into distinct premises and a conclusion helps expose logical gaps and shifts in terminology.
2
Evaluate the relationship between the premises and the conclusion.
The argument uses the word 'independent' to connect the new auditor to the guarantee of an objective analysis. However, the definition of the word shifts drastically between the general rule and the specific application.

Public Health Official: A recent ten-year study tracking thousands of adults found a strong statistical link between shopping at premium health-food retailers and a lower incidence of cardiovascular illness. The researchers noted that the more frequently participants shopped at these stores, the fewer cardiovascular issues they experienced. Clearly, consuming the specialized nutritional products sold at these retailers substantially improves cardiovascular health.

Which of the following most accurately describes a flaw in the public health official's reasoning?

Cevabı ve açıklamayı göster

Cevap: fails to consider that an underlying factor, such as a generally health-conscious lifestyle, could independently lead individuals both to shop at premium health-food retailers and to maintain better cardiovascular health

Cevap

The statement identifying that the argument fails to consider an underlying factor that independently leads to both behaviors.
The correct answer identifies a classic correlation-causation fallacy. The public health official observes a correlation between shopping at health-food stores and better cardiovascular health, immediately concluding that the food causes the health improvement. However, this ignores the possibility of a third factor (such as a preexisting health-conscious lifestyle or higher income level) that causes both the choice of where to shop and the improved health outcomes.

Adım Adım Çözüm

1
Analyze the structure of the argument.
Premise: There is a strong statistical link (correlation) between shopping at premium health-food stores and lower cardiovascular illness. Conclusion: Consuming these products improves cardiovascular health (causation).
Identifying the premises and conclusion is essential to isolating the logical gap.
2
Identify the logical flaw in moving from the premise to the conclusion.
The argument leaps from a correlation between two phenomena to a definitive causal relationship.
Recognizing standard LSAT flawed reasoning patterns helps anticipate the correct answer choice.
3
Evaluate the answer choices against the identified flaw.
The correct option points out the 'third variable' problem—a classic alternate explanation for a correlation, which weakens the causal conclusion.
The correct answer must accurately describe what the argument does wrong without bringing in irrelevant concepts.

Defense Attorney: My client cannot be held liable for the damages. The relevant statute dictates that a person is liable only if their actions were deliberate. However, leading cognitive scientists have demonstrated that all human actions are ultimately driven by subconscious neural mechanisms over which individuals exert no conscious control. Because our actions are determined by these subconscious mechanisms, no human action is ever truly deliberate. Therefore, my client is exempt from liability.

Which of the following most accurately describes a flaw in the defense attorney's reasoning?

Cevabı ve açıklamayı göster

Cevap: It relies on two different and incompatible senses of the word 'deliberate'.

Cevap

The argument is flawed because it relies on two different and incompatible senses of the word 'deliberate'.
The argument's logical breakdown hinges on the word 'deliberate'. In the first premise, 'deliberate' is used in a standard legal sense, meaning an action taken intentionally or purposefully. In the second premise, 'deliberate' is used in a rigid scientific or philosophical sense, meaning an action completely free from prior physical causes or subconscious determinants. Because the term drastically changes meaning, the conclusion that the client is exempt from legal liability does not logically follow.

Adım Adım Çözüm

1
Analyze the attorney's argument structure.
Premise 1: Liability requires deliberate action. Premise 2: Human actions are driven by subconscious mechanisms, so actions are never truly deliberate. Conclusion: The client is not liable.
Deconstructing the argument is necessary to identify logical gaps or linguistic shifts between the premises and the conclusion.
2
Evaluate the use of key terminology across the premises.
The term 'deliberate' in the first premise means 'intentional' or 'willful' (its legal sense). In the second premise, it means 'completely free from subconscious physical determinism' (a metaphysical sense).
Arguments that appear structurally valid but reach highly questionable conclusions often rely on subtle semantic shifts.
3
Identify the logical flaw based on the evaluation.
The argument is flawed because it equivocates on the term 'deliberate', changing its meaning midway to bridge the gap to the conclusion.
For a logical deduction to be valid, key terms must retain a consistent meaning throughout the argument.

Öğeler

Editorial: The mayor has vetoed the city council's proposal to increase downtown parking fees to fund public transit. It is obvious, then, that the mayor simply does not care about improving our public transportation system.
Political Commentator: The administration's diplomatic sanctions have not forced the regime to completely dismantle its weapons program. Therefore, the sanctions are useless and we must immediately resort to military intervention.
School Board Member: We must either mandate that all high school students take four years of advanced mathematics, or resign ourselves to graduating students who are completely unprepared for the modern workforce.
Financial Advisor: Since you cannot afford to put 20 percent of your income into savings every month as I recommended, you might as well not bother trying to save for retirement at all.

Cevap

Editorial pairs with rejecting a specific method. Political Commentator pairs with extreme measure vs. partial success. School Board pairs with strict policy vs. disaster. Financial Advisor pairs with maximum target vs. no progress.
Each argument contains a False Dilemma flaw but manifests it differently. The Editorial restricts options to one specific policy or total apathy. The Commentator restricts options to total success or military action. The School Board Member restricts options to a strict mandate or total failure. The Financial Advisor restricts options to a maximum savings rate or zero savings.

Adım Adım Çözüm

1
Analyze the Editorial's argument
The argument assumes that without the parking fee increase, public transit won't be funded.
To identify that it equates rejecting one specific method with rejecting the overall goal.
2
Analyze the Political Commentator's argument
The argument jumps from the incomplete success of sanctions directly to military intervention.
To recognize the flaw of assuming an extreme measure is the only alternative when a less extreme one isn't perfectly successful.
3
Analyze the School Board Member's argument
The argument presents only two outcomes: four years of advanced math or total lack of workforce preparation.
To spot the presumption that a specific strict policy is the only way to avoid a disastrous outcome.
4
Analyze the Financial Advisor's argument
The argument claims that if a 20 percent savings rate isn't possible, saving anything is worthless.
To identify the false equivalence between missing a maximum target and making no progress at all.

Music Critic: A comprehensive analysis of major symphony orchestras over the last twenty years shows a strong statistical correlation between the frequency of an orchestra playing contemporary compositions and an increase in their annual subscription renewals. Therefore, it is clear that scheduling more contemporary pieces causes audiences to become more loyal and renew their subscriptions.

Which of the following, if true, provide a valid alternative explanation for the correlation that weakens the critic's argument? (Select all that apply)

Cevabı ve açıklamayı göster

Cevap: Orchestras that experience an increase in subscription renewals enjoy larger budgets, which allows them to afford the high licensing fees required to perform contemporary compositions.; A renewed cultural interest in local arts initiatives in certain cities has simultaneously driven both higher orchestra subscription rates and a public demand for avant-garde, contemporary programming.

Cevap

The correct options are the one describing orchestras with increased renewals affording licensing fees (reverse causality) and the one citing a renewed cultural interest driving both factors (third variable).
The argument incorrectly assumes that because two phenomena are correlated, one must cause the other. To weaken this causal claim, one must provide an alternative explanation for the correlation. The correct answers do this by providing a reverse causality scenario (increased renewals lead to more contemporary pieces because of larger budgets) and a third-variable scenario (a general cultural interest causes both).

Adım Adım Çözüm

1
Analyze the argument's structure.
Premise: Correlation between contemporary compositions and subscription renewals. Conclusion: Contemporary compositions cause increased subscription renewals.
Identifying the premise and conclusion is necessary to understand the core reasoning flaw.
2
Identify the logical flaw.
The argument assumes causation based solely on correlation.
Recognizing that correlation does not imply causation allows us to anticipate how to weaken the argument.
3
Determine what would weaken the causal claim.
An alternative explanation for the correlation, such as reverse causality or a third common cause, would weaken the conclusion.
The question asks for valid alternative explanations that undermine the stated cause-and-effect relationship.
4
Evaluate the options against the anticipated weakeners.
The option about larger budgets causing orchestras to afford contemporary pieces shows reverse causation. The option about renewed cultural interest shows a third common cause.
Selecting the options that successfully demonstrate these alternative explanations fulfills the requirements of the question.

Corporate Strategist: Our main competitor has launched a highly successful marketing campaign that is steadily eroding our market share. To survive this competitive threat, we must either launch an equally expensive counter-campaign or resign ourselves to a permanent reduction in our customer base. Since our current cash reserves cannot support a massive new marketing expenditure, we have no choice but to accept a permanently smaller customer base.

The strategist's argument is vulnerable to criticism on the grounds that it illicitly takes for granted that there are no alternative strategies available to address the competitor's threat other than the two explicitly mentioned.

Cevap: True

Cevap

True. The given statement accurately describes a false dilemma, which is the exact logical flaw present in the strategist's argument.
The statement accurately captures the core logical flaw of the argument. A false dilemma (or false dichotomy) occurs when an author artificially limits the available options to a binary choice, eliminates one, and concludes the other must inevitably be true. The strategist fails to consider any alternative business strategies outside of the two extremes provided.

Adım Adım Çözüm

1
Identify the argument's explicit premises.
Premise 1: The company must either launch an expensive counter-campaign or accept a permanent reduction in customers. Premise 2: The company cannot afford the expensive counter-campaign.
Deconstructing the argument into its foundational claims is necessary to evaluate its internal logic.
2
Identify the argument's main conclusion.
Conclusion: The company has no choice but to accept a permanently smaller customer base.
Isolating the conclusion allows us to test if the premises provide sufficient and absolute support for it.
3
Evaluate the link between the premises and the conclusion for unstated assumptions.
The conclusion strictly relies on the first premise being an exhaustive list of all possible realities. The argument assumes no third option exists.
Identifying missing information or gaps in reasoning reveals the logical flaw.
4
Compare the identified flaw with the provided evaluation statement.
The statement correctly points out that the argument ignores alternative strategies. This accurately describes the false dichotomy used by the strategist.
This comparison directly determines whether the statement provided in the prompt is true or false.
