- It can be inferred that the use of money...
Answer: simplifies transactions between people who may not want each other's specific goods.
The correct answer is A. By highlighting the main limitation of bartering (the need for a "double coincidence of wants"), the passage implies that money, the alternative, solves this problem. Money acts as an intermediary, so you don't need to find someone who wants your specific goods. B is incorrect and nonsensical. C describes bartering, not the use of money. D is contradicted by the passage, which states bartering was the primary form of trade for "much of human history," implying it is the older system.
- It can be inferred from the passage that...
Answer: a person's expectations can affect their physical condition.
The correct answer is A. The passage attributes the health improvements to the patient's "belief in a cure," which is a type of expectation. B is directly contradicted by the definition of the placebo effect, which involves "real health improvements." C is too extreme; the passage calls belief a "powerful factor," not the "only factor." D is contradicted by the mention of "ongoing medical research," which implies the topic is not yet fully understood.
- What can be inferred about the previous barriers to festival attendance?
Answer: Younger people were unaware of the festival and needed convenient travel arrangements to participate, suggesting marketing and accessibility issues.
The success of both social media promotion (awareness) and hotel partnerships (accessibility) suggests these were the primary barriers. The dramatic increase with young families indicates interest existed but required better promotion and logistics. Choice A focuses only on entertainment value. Choice B emphasizes only accessibility. Choice D introduces cost issues not mentioned in the passage.
- What can be inferred about the relationship between performance type and audience preferences?
Answer: Certain performance genres align better with either formal, attentive viewing or casual, social experiences based on audience expectations.
When you encounter inference questions about patterns in data or behavior, focus on what the evidence directly supports rather than making broad generalizations or value judgments.
The passage presents clear evidence about audience preferences: drama and classical music audiences chose traditional orchestra seating and valued "focused attention," while comedy and contemporary music audiences preferred table seating and appreciated the "relaxed atmosphere." This pattern suggests that different performance types naturally align with different viewing experiences based on what audiences expect from each genre. Answer D captures this relationship accurately.
Answer A overgeneralizes by claiming "contemporary audiences prefer dining experiences...regardless of the type of performance." The passage shows this isn't true—drama audiences still chose traditional seating, proving performance type does matter.
Answer B focuses on profitability, but the passage provides no information about theater profits or revenue comparisons between seating types. This introduces information not supported by the text.
Answer C makes value judgments about art forms being "superior" or "less serious." The passage describes different audience preferences without ranking the artistic merit of different performance types. Inference questions test your ability to stick to what's actually stated or logically supported.
Remember: strong inferences stay close to the evidence provided. Avoid answers that make sweeping generalizations, introduce unsupported topics, or impose value judgments that weren't present in the original text. Look for patterns the data actually demonstrates.
- What can be inferred from the passage?
Answer: The effectiveness of a leadership style may be related to the nature of the team.
The correct answer is A. The passage states that introverted leaders can be more effective with proactive teams, which implies that the situation and the team's characteristics affect a leader's success. B is an overgeneralization; the passage says introverts can be more effective, not that they are always superior. C is an incorrect inference; stating that introverts are better listeners does not mean extroverts are bad listeners or don't value ideas. D is contradicted by the first sentence, which introduces a common belief that the passage then questions.
- What can be inferred about decision-making from this passage?
Answer: The quality of a person's choices can decline when they have to make many of them.
The correct answer is A. The passage defines decision fatigue as the deterioration of the ability to make good choices after a long session of decision-making, which is a direct paraphrase of this option. B is an incorrect limitation; shopping is used as an example, but the concept itself is more general. C is not supported; the passage describes the phenomenon but does not mention any way to prevent it. D is too absolute; the passage says a shopper might make a poor purchase, not that they always will.
- The passage suggests that before the printing press...
Answer: written knowledge was available to only a limited part of the population.
The correct answer is A. The passage states that books were "rare and expensive" and that the press made knowledge "more accessible to the common person," which implies that before the press, access was limited. B is not supported; the passage discusses the lack of access, not a lack of interest. C is unlikely and not stated; hand-copying is generally slow, and the text implies the press was a major improvement. D is contradicted; the fact that books were carefully copied in monasteries suggests they were considered very important.
- The passage implies that the main purpose of hibernation is...
Answer: to manage limited resources during challenging times.
The correct answer is A. The passage states that hibernation helps an animal "conserve energy" when "food is scarce," which is a way of managing limited resources. B is incorrect; hibernation is a response to scarcity (winter), not preparation for abundance (summer). C is directly contradicted by the statement "Not all bears truly hibernate." D is also contradicted; the passage clearly states that hibernation involves dramatic slowing of heart rate, breathing, and metabolism.
- What can be reasonably inferred about Maria's evening classes?
Answer: They provide her with mental stimulation that carries over positively to her work performance despite causing scheduling conflicts.
The passage indicates Maria arrives late on Tuesday and Thursday (suggesting Monday and Wednesday night classes) but is more energetic and creative on those same afternoons. This supports the inference that the classes provide mental stimulation that benefits her work. Choice A assumes the classes are accounting-related without evidence. Choice B incorrectly suggests she's tired when she's actually more energetic. Choice D contradicts the context that she chose to take these classes.
- The passage suggests that a key skill for a jazz musician is...
Answer: the ability to create new musical ideas while playing.
The correct answer is A. The passage's focus on "improvisation" and creating "spontaneous solos" directly points to the skill of creating music in the moment. B is the opposite of what is described; the passage states that no two performances are alike. C is not mentioned; while it might be helpful, the passage does not identify it as a key skill for jazz. D is contradicted by the mention of musicians who "interact with each other in the moment."
- The passage suggests that urban gardening...
Answer: offers social and environmental advantages to city dwellers.
The correct answer is A. The passage states that urban gardening can "strengthen community bonds" (a social advantage) and "improve the local environment" (an environmental advantage). B is an extreme claim not supported by the text. C is not mentioned; the passage doesn't discuss the required skill level or cost. D makes a comparison to traditional farming that is not present in the passage.
- What can be inferred about the relationship between sleep and different types of cognitive performance during stressful periods?
Answer: Sleep deprivation enhances certain cognitive functions like memorization while impairing others like analytical thinking and stress management.
When you encounter reading comprehension questions about research studies, focus on what the data actually shows rather than making assumptions beyond the evidence presented.
Looking at Dr. Martinez's study results, we can see a clear pattern: Group A (normal sleep) performed better on memorization tasks, while Group B (extra sleep) excelled at problem-solving and analytical questions. This suggests that different sleep amounts affect cognitive functions differently. Since Group A had less sleep during exam week (maintaining "normal" schedules during a stressful period likely means insufficient sleep), this indicates that sleep deprivation may actually enhance memorization while impairing analytical thinking. The fact that Group B reported less stress also supports that adequate sleep improves stress management.
Answer choice A is wrong because the study shows extra sleep doesn't improve all aspects—Group B actually performed worse on memorization questions. Choice B incorrectly assumes Group B had "altered sleep schedules" that created stress, but the passage indicates they felt less stressed. Choice C makes an unsupported claim about overconfidence and suggests Group B was "less focused," when their superior performance on complex reasoning shows they were quite focused.
Answer D correctly captures what the evidence demonstrates: sleep deprivation (Group A's situation during stressful exam week) enhanced memorization but impaired analytical thinking and stress management.
For inference questions on research passages, stick closely to what the data shows. Avoid answer choices that make claims beyond the study's scope or contradict the presented evidence. Look for patterns in the results rather than making assumptions about underlying causes.
- What can be inferred about the project manager's strategy for meeting the deadline?
Answer: The manager plans to compensate for delays in one section by accelerating work in areas where original methods can still be used.
The passage indicates soil problems were specific to the downtown section, and the manager plans to hire more crews and work extended hours on 'remaining sections,' suggesting acceleration where original methods work. Choice A assumes problems will spread without evidence. Choice C introduces safety concerns not mentioned. Choice D suggests scope reduction not indicated in the passage.
- Based on the passage, what is the most important factor in defining a desert?
Answer: The amount of moisture an area receives.
The correct answer is A. The passage defines deserts by "low rainfall" and gives polar regions as an example due to "extremely low" precipitation. This shows that moisture is the key factor. B is incorrect because the passage explicitly contrasts hot deserts with "cold deserts." C is incorrect as the passage states "not all are hot and sandy." D is incorrect because the passage mentions "the few life forms that have adapted to survive there," indicating life is present.
- What can be inferred from the passage?
Answer: Modern technology may have changed what we consider a normal sleep schedule.
The correct answer is A. The passage contrasts the modern idea of sleep with a historical pattern that existed before "artificial lighting," a modern technology. This implies a link between the technology and the change in sleep norms. B is not stated; the passage doesn't mention the total hours slept. C makes a health claim ("healthier") that the passage does not support; it only says the pattern was "common." D is too absolute; "common" does not mean "everyone."
- It can be inferred from the passage that a good approach to reading poetry is to...
Answer: be open to finding meaning through feelings and interpretation.
The correct answer is A. The passage says poetry aims to "evoke emotions and ideas" and that its meaning is "felt and interpreted." This implies that a reader should be open to this less direct way of finding meaning. B is contradicted by the contrast with prose that aims for direct clarity. C is contradicted by the word "interpreted," which suggests that multiple valid readings are possible. D is illogical; ignoring the unconventional language would mean missing the metaphors and symbolism that the passage identifies as central to poetry.
- What does the passage imply?
Answer: A lease contains important rules that can affect a tenant's finances and lifestyle.
The correct answer is A. The passage mentions penalties (affecting finances) and guest policies/rules for changes (affecting lifestyle) as important details. This supports the inference that the document has significant consequences. B is directly contradicted by the advice to "read the entire document carefully." C is incorrect because the passage lists several other important details besides rent. D is implied to be false, as the advice to read carefully suggests that leases can differ in their specific clauses.
- Based on the information provided, what can be inferred about the lighthouse keeper's approach to his duties?
Answer: He prioritized consistent safety protocols over resource conservation, maintaining readiness regardless of seasonal patterns.
The passage shows the keeper lit the beacon every night despite knowing ships needed guidance more in certain months, indicating he prioritized consistent safety over resource efficiency. Choice A judges his efficiency negatively without considering safety priorities. Choice C is wrong because he clearly tracked weather patterns in his journal. Choice D contradicts the fact that he maintained the beacon year-round.
- What can be inferred about the nature of the bookstore's previous financial difficulties?
Answer: The store had valuable merchandise but insufficient exposure to reach customers willing to pay for specialized items.
The immediate success after social media exposure, especially from distant customers, suggests the store had desirable products but lacked visibility to reach its target market. Choice A is wrong because the inventory was already valuable before being featured. Choice B is contradicted by the successful online sales. Choice D introduces customer service issues not mentioned in the passage.
- What can be inferred about the different usage patterns between the two types of locations?
Answer: Office building stations serve commuters with predictable round-trip patterns, while recreational stations serve leisure users with more varied routes.
The evidence supports different user types: office workers with routine commute patterns (same pickup/return stations, rush hour timing) versus recreational users with varied destinations (different return stations, all-day usage). Choice B confuses steady usage with popularity. Choice C makes value judgments about responsibility not supported by the data. Choice D assumes success based on predictability without evidence.
