SECTION 1: Logical Reasoning - Argument Analysis and Flaw Identification
Questions 1-25 | Flaw identification, argument structure, assumption identification
A prominent philosopher argues that free will must exist because humans are capable of making genuine choices. She supports
this by noting that people routinely deliberate between alternatives and act on their decisions. Since deliberation presupposes
the ability to have chosen otherwise, she concludes, free will is real.
Q1. The philosopher's reasoning is most vulnerable to criticism because it:
A. presumes that the act of deliberation necessarily implies the existence of free will, without establishing that
deliberation cannot occur in a deterministic framework [CORRECT]
B. fails to consider that some choices people make are influenced by unconscious biological processes beyond their
control
C. takes for granted that genuine choices exist simply because people believe they are making choices
D. relies on anecdotal evidence of deliberation rather than controlled scientific studies of decision-making
Correct Answer: A
Rationale:
The argument commits circular reasoning: it assumes free will to prove free will. The philosopher claims that deliberation presupposes
free will (genuine alternatives), but this is precisely what needs to be proven. Deliberation could occur in a deterministic framework where
one simply follows causal chains. Answer A correctly identifies this circularity. Answer B introduces an alternative explanation but misses
the core logical flaw. Answer C misidentifies the circularity as a presumption about genuine choices based on belief. Answer D
incorrectly focuses on evidence quality rather than the argument's internal structure.
Dr. Thornton, a well-known climate scientist, recently published a study concluding that global temperatures will rise by at
least 3 degrees Celsius by 2100 under current emission trends. A blogger critical of climate action argues that Dr. Thornton's
conclusions should be dismissed because she once accepted research funding from an environmental advocacy group, and
therefore her findings are biased.
Q2. The blogger's argument is flawed because it:
A. fails to provide any scientific evidence contradicting Dr. Thornton's specific temperature projections
B. attacks Dr. Thornton's character and funding sources rather than engaging with the substance of her
research methodology [CORRECT]
C. assumes that all scientists who receive funding from advocacy groups produce biased results
D. overlooks the possibility that Dr. Thornton's study was peer-reviewed by independent experts before publication
Correct Answer: B
Rationale:
The blogger commits the ad hominem fallacy, attacking the person (Dr. Thornton) rather than the argument itself. By focusing on funding
sources rather than the study's methodology, data, or reasoning, the blogger avoids engaging with the actual scientific claims. Answer B
precisely identifies this ad hominem reasoning. Answer A is true but describes a different weakness (lack of counter-evidence) rather than
identifying the specific fallacy. Answer C describes a hasty generalization but the blogger targets one specific scientist. Answer D raises a
valid point but is not the primary logical flaw in the argument's structure.
A study found that cities with more public parks per capita have lower rates of depression among residents. The city council of
Millfield, which has the fewest parks per capita in the state, concludes that building five new parks will significantly reduce
depression rates in the city.
Q3. The city council's reasoning is most vulnerable to which of the following criticisms?
2
, LSAT Practice Prep Exam 2026 | 100 Questions | Verified Answers
A. It fails to consider that depression rates may be influenced by multiple factors such as economic conditions, social
support networks, and access to healthcare
B. It assumes that the correlation between parks and lower depression in other cities implies a causal relationship
C. It overlooks the possibility that people with lower depression rates may choose to live in cities with more parks
D. Both A and B describe significant flaws in the council's reasoning [CORRECT]
Correct Answer: D
Rationale:
The council's argument exhibits two major flaws. First, it commits causal oversimplification by assuming parks alone cause lower
depression, ignoring confounding variables like economic conditions, healthcare access, and social support (Answer A). Second, it
confuses correlation with causation; the study only shows an association, not that parks cause lower depression (Answer B). Additionally,
the reverse causality in Answer C (people with better mental health choosing greener cities) is also a valid concern. Since both A and B
independently identify major flaws, Answer D is the strongest response.
A school board member argues: 'We must either increase class sizes to thirty-five students per room or eliminate the music
program entirely. Since eliminating music would be devastating to students' creative development, we have no choice but to
increase class sizes.'
Q4. The argument is flawed because it:
A. assumes that the music program is the only program that contributes to students' creative development
B. presents only two options when other alternatives, such as reducing administrative costs or seeking
additional funding, may exist [CORRECT]
C. fails to establish that increasing class sizes would actually generate sufficient savings to maintain the music program
D. takes for granted that the school district faces a budget deficit that requires any cuts at all
Correct Answer: B
Rationale:
The argument commits the false dichotomy fallacy by presenting only two extreme options (increase class sizes or eliminate music) while
ignoring other possibilities like reducing administrative overhead, increasing revenue through taxes, or making smaller cuts across
multiple programs. Answer B correctly identifies this false dichotomy. Answer A mischaracterizes the argument. Answer C raises a
practical concern but not a logical flaw. Answer D incorrectly challenges a premise that the argument does, in fact, establish (the need for
some response to a budget constraint).
A political commentator states: 'The government has no right to interfere with personal liberty. Taxes interfere with personal
liberty by taking away money that individuals earned. Therefore, all taxes are violations of fundamental rights.' However, in
political philosophy, 'liberty' in the phrase 'personal liberty' typically refers to bodily autonomy and freedom of conscience, not
freedom from taxation.
Q5. The commentator's argument is flawed because it:
A. equivocates on the meaning of 'liberty,' using it in the broad sense of 'freedom from government interference' in the
premise and the narrower sense of 'bodily autonomy' in the conclusion
B. assumes that all forms of government interference are equivalent in severity and moral significance
C. fails to distinguish between negative liberty (freedom from interference) and positive liberty (freedom to achieve
one's potential)
D. relies on a definition of liberty that is inconsistent with how the term is used in the political philosophy
referenced [CORRECT]
Correct Answer: D
Rationale:
The commentator uses 'personal liberty' in a broad colloquial sense (freedom from any government interference, including taxes) but the
philosophical context defines 'personal liberty' more narrowly (bodily autonomy and freedom of conscience). This is equivocation,
shifting the meaning of a key term mid-argument. Answer D correctly identifies this definitional inconsistency. Answer A reverses the
3
, LSAT Practice Prep Exam 2026 | 100 Questions | Verified Answers
direction of the equivocation. Answer B describes a different fallacy. Answer C, while philosophically relevant, doesn't capture the
specific equivocation at play.
A nutritionist claims that a diet consisting entirely of raw vegetables is the healthiest possible diet. When challenged with
evidence that such a diet can cause nutrient deficiencies, the nutritionist responds: 'Dr. Hartwell, a Nobel laureate in medicine,
endorsed raw vegetable diets in his book, so the diet must be healthy.'
Q6. The nutritionist's response is flawed because it:
A. cites an authority figure whose expertise in nutrition is not established by winning a Nobel Prize in medicine
B. appeals to authority rather than addressing the specific evidence about nutrient deficiencies [CORRECT]
C. assumes that Dr. Hartwell's endorsement was based on rigorous scientific evidence rather than personal opinion
D. fails to consider that nutritional science may have advanced since Dr. Hartwell's book was published
Correct Answer: B
Rationale:
The nutritionist commits the appeal to authority fallacy. Instead of responding to the specific evidence about nutrient deficiencies with
counter-evidence, the nutritionist deflects by citing a prestigious name. Answer B identifies this core flaw. While Answers A and D raise
valid concerns about the authority's relevance and timeliness, they elaborate on why the appeal is weak rather than identifying the
fundamental reasoning error. Answer C makes an unsupported assumption about the authority's reasoning process.
The CEO of TechCorp argues that the company should not invest in developing an artificial intelligence division because no
AI startup has ever achieved sustained profitability. Therefore, TechCorp's investment in AI would also fail to be profitable.
Q7. The CEO's argument depends on which of the following assumptions?
A. That TechCorp lacks the financial resources to sustain losses during the initial years of an AI division
B. That the conditions that prevented AI startups from achieving profitability would also apply to TechCorp's
AI division [CORRECT]
C. That artificial intelligence technology has not advanced significantly enough to create profitable applications
D. That TechCorp's current management team lacks the expertise to run an AI division successfully
Correct Answer: B
Rationale:
The CEO draws a conclusion about TechCorp based on evidence about AI startups. For this inference to be valid, the CEO must assume
that the conditions causing startup failures would similarly affect TechCorp, despite their differences in size, resources, and market
position. This is a necessary assumption because if TechCorp's situation were fundamentally different from startups, the startup evidence
would not support the conclusion about TechCorp. Answer B identifies this critical assumption. Answers A, C, and D describe possible
contributing factors but are not required for the argument's logic.
A doctor tells a patient: 'If you take this medication daily, your blood pressure will improve. Since your blood pressure has
improved, you must have taken the medication daily.'
Q8. The doctor's reasoning is flawed because it:
A. confuses a sufficient condition with a necessary condition, concluding from the result that the condition must
have been met when other factors could have produced the same result [CORRECT]
B. fails to consider that the medication may have side effects that could worsen other aspects of the patient's health
C. assumes that the medication is the only treatment available for high blood pressure
D. does not account for the possibility that the patient's blood pressure improved temporarily but may worsen again
Correct Answer: A
