Critical Reading and Inference Questions Flashcards

"The town council approved the new zoning ordinance by a 5–2 vote despite a packed public hearing at which the majority of speakers opposed the measure." Which of the following can be most reasonably inferred from the statement above? (A) The council members were influenced by speakers at the public hearing (B) The council acted without considering public input (C) The council's vote did not reflect the sentiment expressed at the public hearing (D) Public hearings are ineffective because officials ignore them

Answer: The council's vote did not reflect the sentiment expressed at the public hearing

The passage states most speakers opposed the measure, yet the council passed it 5–2. The most direct inference is that the vote did not reflect the hearing's sentiment.

"Studies consistently show that countries with higher rates of newspaper readership also have higher levels of civic participation. Researchers have concluded that reading newspapers causes greater civic engagement." Which logical flaw does this argument contain? (A) It ignores the sample size of the studies (B) It assumes correlation implies causation (C) It fails to define civic participation (D) It relies on surveys rather than direct observation

Answer: It assumes correlation implies causation

The studies show a correlation between newspaper readership and civic participation. Concluding causation from correlation is a classic logical fallacy.

"The wildlife preserve was established in 1985 to protect the endangered salt marsh harvest mouse. In 1995, the mouse population within the preserve stood at 12,000. By 2010, the population had grown to 38,000." Which conclusion is best supported by this information? (A) The preserve is the most effective tool ever created to protect endangered species (B) The salt marsh harvest mouse has fully recovered as a species (C) Population growth of the mouse occurred within the protected area during this period (D) Predators were removed from the preserve during this period

Answer: Population growth of the mouse occurred within the protected area during this period

The only thing directly stated is the population within the preserve grew from 12,000 to 38,000. All other conclusions go beyond the evidence.

A public health official states: "If we do not mandate mask-wearing in schools, we will definitely see a spike in flu cases this winter." Which of the following, if true, most weakens this argument? (A) Some students are unable to wear masks due to medical conditions (B) Last winter, mask mandates in neighboring districts did not prevent a flu spike (C) Flu vaccines are widely available and have 70% effectiveness (D) Teachers have expressed support for mask mandates

Answer: Last winter, mask mandates in neighboring districts did not prevent a flu spike

If mask mandates did not prevent flu spikes elsewhere, this directly undermines the claim that mandates will prevent a spike here.

Passage: "Ocean acidification occurs when seawater absorbs carbon dioxide from the atmosphere, forming carbonic acid. Marine biologists warn that this threatens shellfish populations because acid dissolves the calcium carbonate that forms their shells. Some economists argue that market forces will adapt: shellfish prices will rise, reducing demand, and producers will shift to other seafood." The economists' argument assumes which of the following? (A) Shellfish are not nutritionally important to human diets (B) Market adjustments can compensate for ecological damage (C) Carbon dioxide emissions will stabilize in the near future (D) Shellfish producers already have plans to diversify

Answer: Market adjustments can compensate for ecological damage

The economists argue that market shifts (price changes, product substitution) will handle the problem — this assumes economic adaptation can address ecological harm.

"Professor Chen argued that Shakespeare did not write his own plays because he lacked sufficient formal education and had no documented access to the books cited in the plays. However, historical records from Elizabethan England are notoriously incomplete." The final sentence most likely serves to: (A) Provide a definitive rebuttal to Professor Chen's argument (B) Suggest that absence of evidence is not evidence of absence (C) Confirm that Shakespeare's education was limited (D) Indicate that historical research is generally unreliable

Answer: Suggest that absence of evidence is not evidence of absence

Chen argues from lack of documentation; the final sentence notes records are incomplete, suggesting the absence of documents doesn't prove the books weren't accessed.

A restaurant review reads: "The service was prompt, the ambiance was pleasant, and the wine list was impressive. The entrées, however, were disappointing — overpriced, underseasoned, and served cold." A reader can most reasonably conclude that the reviewer would: (A) Recommend the restaurant for dinner (B) Not recommend the restaurant primarily based on the food quality (C) Recommend the restaurant primarily for its wine and ambiance (D) Give the restaurant a mixed but overall positive review

Answer: Not recommend the restaurant primarily based on the food quality

For a restaurant, the food quality is central. The entrées — the main course — were 'disappointing, overpriced, underseasoned, cold,' making a primary recommendation difficult despite other positives.

"The graph shows that as income rises, happiness initially increases rapidly, but above $75,000 annual income, additional income produces diminishing gains in happiness." Which of the following is an inference supported by the graph's description? (A) Money cannot buy happiness (B) People earning over $75,000 are always happier than those earning less (C) The marginal benefit of income on happiness decreases above a certain threshold (D) Happiness depends entirely on factors unrelated to income

Answer: The marginal benefit of income on happiness decreases above a certain threshold

The description explicitly states 'diminishing gains' above $75,000 — this is the economic concept of diminishing marginal returns.

"Despite decades of research, scientists have not identified a single gene responsible for intelligence. Instead, studies of twins suggest that hundreds of genes each contribute small effects, and that environment accounts for roughly half the variance in intelligence." Which of the following is most consistent with the passage? (A) Intelligence cannot be measured accurately (B) Genes are irrelevant to intelligence (C) Intelligence is influenced by both heredity and environment (D) Twin studies are the most reliable method for measuring genetic influence

Answer: Intelligence is influenced by both heredity and environment

The passage says hundreds of genes contribute and environment accounts for roughly half the variance — both genetics and environment play significant roles.

A senator argues: "We should not cut the defense budget. Every time we have cut defense spending in the past, our adversaries have become more aggressive." Which of the following, if true, most seriously undermines the senator's argument? (A) Defense contractors are significant campaign donors (B) The most recent cut in defense spending was followed by improved diplomatic relations (C) Other countries spend less on defense than the United States (D) Reduced defense spending could fund domestic programs

Answer: The most recent cut in defense spending was followed by improved diplomatic relations

If the most recent cut led to improved (not worsened) relations, this directly provides a counter-example to the senator's historical claim.

"The Romantic poets valued emotional authenticity and individual experience over the rationalism of the Enlightenment. Yet Byron, Shelley, and Keats were all highly educated in classical literature, philosophy, and political theory." What is the primary purpose of the second sentence? (A) To contradict the characterization of Romanticism (B) To show that the Romantics were hypocrites (C) To add nuance by showing that rejecting rationalism did not mean rejecting learning (D) To prove that the Romantic movement was part of the Enlightenment tradition

Answer: To add nuance by showing that rejecting rationalism did not mean rejecting learning

The second sentence doesn't contradict the first — it adds nuance: the Romantics could value emotion while still being deeply learned.

"Numerous studies have linked sitting for more than 8 hours a day to increased risk of cardiovascular disease, diabetes, and early mortality. These risks were not significantly reduced by exercising for 30 minutes daily." Which conclusion is most strongly supported by this information? (A) Exercise is ineffective for maintaining good health (B) A single 30-minute workout cannot undo the harm from prolonged sitting (C) Office workers are inevitably doomed to poor health (D) Standing desks eliminate the risks of prolonged sitting

Answer: A single 30-minute workout cannot undo the harm from prolonged sitting

The passage specifically states that 30 minutes of exercise did not reduce the sitting risks — this directly supports Option B.

"The school district reported that students at schools using tablet computers scored 12% higher on standardized tests than students at schools without tablets." Which of the following is the most important limitation to consider before accepting this finding? (A) Tablets may damage students' eyesight over time (B) The schools with tablets may differ from schools without tablets in ways that also affect scores (C) 12% is not a statistically significant difference (D) Teachers may not be trained to use tablet technology effectively

Answer: The schools with tablets may differ from schools without tablets in ways that other factors also affect scores

Without random assignment, schools with tablets may be wealthier, better-staffed, or serve higher-income students — confounding variables make causation unclear.

Philosopher A argues: "Free will is impossible because every thought we have is the product of prior neurological states, which are themselves determined by genetics and environment." Philosopher B most effectively counters this argument by saying: (A) "Neuroscience is an imprecise science." (B) "Some people clearly make choices that contradict their genetic predispositions." (C) "Determinism and free will may be compatible if free will means acting on one's own desires, even if those desires have prior causes." (D) "Many cultures believe in free will, which provides strong evidence for its existence."

Answer: Determinism and free will may be compatible if free will means acting on one's own desires, even if those desires have prior causes.

Option C introduces compatibilism — the philosophical position that determinism and free will can coexist. It directly engages with Philosopher A's argument at the conceptual level.

"The city's recycling rate has climbed steadily from 22% in 2010 to 58% in 2023. Officials credit the success to a financial incentive program launched in 2012 that rewards households for recycling." Which of the following would most strengthen the claim that the incentive program caused the increase? (A) A similar city without the program saw no change in recycling rates from 2010 to 2023 (B) Recycling infrastructure in the city improved significantly between 2012 and 2023 (C) Survey data show that residents are aware of the incentive program (D) The program received national media attention in 2015

Answer: A similar city without the program saw no change in recycling rates from 2010 to 2023

A control comparison — a similar city without the program that showed no improvement — would strongly support causation by ruling out broader trends.

"More than 70% of doctors surveyed said they would recommend Drug X for certain chronic conditions. However, the survey was sponsored by the pharmaceutical company that manufactures Drug X." Which of the following is the most appropriate response to this information? (A) Disregard the survey entirely since it is sponsored by the manufacturer (B) Accept the finding since doctors are medical experts (C) Consider the finding but note that the survey's funding source creates a potential bias (D) Assume that the manufacturer manipulated the results

Answer: Consider the finding but note that the survey's funding source creates a potential bias

Funding source can create bias without outright manipulation. The appropriate response is critical consideration, not blanket dismissal or acceptance.

"Studies show that children who read for pleasure before age 8 tend to score higher on reading comprehension tests throughout school." Which of the following would most WEAKEN the inference that early pleasure reading causes better reading scores? (A) Schools with strong reading programs also encourage pleasure reading at home (B) Many children who don't read for pleasure also score highly on comprehension tests (C) Children who score highly on reading tests often come from households where adults read frequently (D) Reading comprehension tests may not fully measure all aspects of literacy

Answer: Children who score highly on reading tests often come from households where adults read frequently

If household reading environment predicts both pleasure reading AND test scores, it could be the real cause — pleasure reading would be a correlate, not the cause.

"The author argues that urbanization has made society more atomized and lonely, pointing to rising rates of social media use, declining club memberships, and smaller household sizes." Which of the following, if true, would most CHALLENGE the author's conclusion? (A) Social media use has also increased in rural areas (B) People in large cities report higher average life satisfaction than rural residents in multiple surveys (C) Club membership has declined in part because of online communities that provide similar social functions (D) Smaller household sizes reflect lifestyle choices rather than involuntary isolation

Answer: People in large cities report higher average life satisfaction than rural residents in multiple surveys

If urban residents report higher life satisfaction than rural residents, this directly contradicts the claim that urbanization makes society lonelier.

A passage states: "Although consumption of red meat has been linked to cardiovascular disease in some epidemiological studies, other research suggests that processed red meat (such as hot dogs and bacon) drives the risk, while unprocessed red meat poses minimal additional risk." This passage implies that: (A) All red meat should be avoided to prevent cardiovascular disease (B) Epidemiological studies are unreliable for studying diet (C) The relationship between red meat and cardiovascular disease may depend on processing method (D) Unprocessed red meat is definitively safe to eat in large quantities

Answer: The relationship between red meat and cardiovascular disease may depend on processing method

The passage distinguishes between processed and unprocessed red meat and their different risk profiles, implying that processing method matters.

"The company's new CEO was hired specifically to cut costs and restructure operations. In the first year of her tenure, operating costs fell by 18%, though employee headcount decreased by 12%." Which of the following can be inferred from this information? (A) The CEO's cost-cutting was achieved entirely through layoffs (B) The remaining employees became more productive (C) The cost reduction occurred while a significant reduction in workforce also occurred (D) The CEO was successful because she cut more costs than employees

Answer: The cost reduction occurred while a significant reduction in workforce also occurred

The passage states both an 18% cost reduction and a 12% headcount decrease in the same period. The only safe inference is that both occurred simultaneously.
