- Which evidence best supports the argument that environmental factors were the primary cause of Maya civilization's collapse?
Answer: Maya settlements in highland regions with different climate patterns continued to thrive long after lowland cities were abandoned.
When you encounter reading comprehension questions about cause-and-effect arguments, look for evidence that most directly supports the specific claim being made. Here, you need to identify which piece of evidence best supports environmental factors as the primary cause of Maya collapse.
Choice C provides the strongest evidence because it shows a clear pattern: Maya settlements in areas with different climates survived while those in drought-affected lowlands collapsed. This differential survival based on environmental conditions suggests that climate was indeed the primary factor. If political instability, warfare, or overpopulation were the main causes, you would expect both highland and lowland settlements to collapse regardless of their climate patterns.
Choice A is tempting because it establishes that severe drought occurred, but it only proves correlation, not causation. The timing could be coincidental. Choice B shows that people migrated during the drought, but this could indicate drought was just one factor among many rather than the primary cause. Choice D explains why the Maya were vulnerable to drought but doesn't prove environmental factors were more important than social or political issues.
The key insight is that C demonstrates what scientists call a "natural experiment" - when similar populations in different environmental conditions have different outcomes, it strongly suggests the environmental difference is the crucial variable. This type of comparative evidence is often the most compelling support for claims about primary causation.
Remember: when evaluating cause-and-effect arguments, look for evidence that shows differential outcomes based on the proposed causal factor, not just correlation or contributing factors.
- Which of the following details strengthens the author's claim about music training improving auditory attention?
The author concludes that learning an instrument can sharpen auditory attention, helping students distinguish important sounds from background noise. The passage argues that music practice requires sustained focus on pitch, rhythm, and timing, which may strengthen the brain's ability to process complex sound patterns. Although the author does not claim that music training guarantees higher grades, the author suggests it can support listening skills useful in classrooms.
The author cites a study comparing adolescents with at least 3 years of instrumental training to peers with no formal training. In a laboratory task, participants listened to overlapping voices and had to repeat a target sentence while ignoring distractions. The music-trained group performed more accurately and showed faster response times. Researchers also reported stronger neural responses to the target voice in noninvasive recordings, suggesting more efficient sound processing.
The author acknowledges that students who choose music may differ in motivation, which complicates interpretation. However, the author notes that the study controlled for several background factors, including age and baseline reading ability. Therefore, the author concludes that music training is plausibly linked to improved auditory attention, even if further research is needed.
Answer: Music-trained adolescents repeated target sentences more accurately amid overlapping voices and responded faster than peers.
This question tests ISEE Upper Level reading comprehension skills, specifically the ability to select evidence that supports a conclusion. In reading comprehension, identifying supporting evidence involves determining which details directly uphold the main argument or conclusion. This requires understanding the text's logical structure and the role of each piece of information. In the passage, the author presents the argument that music training sharpens auditory attention, and provides evidence such as the study's accuracy and speed results. The correct answer, Choice A, is correct because it directly supports the author's conclusion by showing better performance in trained adolescents. This choice aligns with the main argument by evidencing sound processing gains. Choice C is incorrect because it discusses motivation without direct links to attention. This error often occurs when students select caveats over core data. To help students: Encourage them to map the argument structure and note how each piece of evidence fits. Practice identifying evidence that directly supports conclusions in various texts. Watch for: focusing on irrelevant details or opinions instead of logical support.
- Which of the following details strengthens the author's claim about light pollution harming night ecosystems?
The author argues that artificial light at night, often called light pollution, can disrupt ecosystems even when it seems harmless to humans. The central conclusion is that reducing unnecessary nighttime lighting protects wildlife while preserving human safety. The passage explains that many species rely on darkness to navigate, hunt, and reproduce, and that constant illumination can alter these behaviors.
To support this argument, the author describes research on sea turtle hatchlings along coastal beaches. In controlled observations, hatchlings exposed to bright beachfront lighting were more likely to crawl inland rather than toward the moonlit ocean horizon. This misdirection increased dehydration and predation risk. The author also mentions studies of migrating birds that circle illuminated buildings, wasting energy and increasing collision rates.
Furthermore, the author notes that solutions can be practical. Shielded fixtures direct light downward, and warmer-colored bulbs reduce the blue wavelengths that many animals find especially disruptive. Several towns that adopted "dark-sky" lighting ordinances reported lower electricity use without increases in nighttime accidents. Therefore, the author concludes that thoughtful lighting design can protect ecosystems and still meet human needs.
Answer: Hatchlings exposed to bright beachfront lighting crawled inland more often, increasing dehydration and predation risks.
This question tests ISEE Upper Level reading comprehension skills, specifically the ability to select evidence that supports a conclusion. In reading comprehension, identifying supporting evidence involves determining which details directly uphold the main argument or conclusion. This requires understanding the text's logical structure and the role of each piece of information. In the passage, the author presents the argument that light pollution disrupts ecosystems, and provides evidence such as sea turtle hatchlings' misdirection. The correct answer, Choice A, is correct because it directly supports the author's conclusion by showing behavioral harm and risks from lighting. This choice aligns with the main argument by illustrating wildlife vulnerability. Choice B is incorrect because it defines pollution without harm evidence. This error often occurs when students choose definitions over specific impacts. To help students: Encourage them to map the argument structure and note how each piece of evidence fits. Practice identifying evidence that directly supports conclusions in various texts. Watch for: focusing on irrelevant details or opinions instead of logical support.
- Which piece of evidence best supports the author's main argument?
The author concludes that the Apollo program's legacy extends beyond the 1969 moon landing because it accelerated technological development and reshaped scientific management. While the dramatic image of Neil Armstrong stepping onto the lunar surface on July 20, 1969, is central to public memory, the author argues that the program's deeper impact lay in the systems created to meet unprecedented engineering challenges. These systems included rigorous testing protocols, complex supply chains, and new approaches to coordinating thousands of specialists.
The passage cites NASA reports describing how components were repeatedly tested under extreme conditions, from vibration to temperature swings. It also notes that contractors had to document failures and redesign parts quickly, creating a culture in which problems were expected and analyzed rather than hidden. Secondary sources quoted by the author point to spinoff technologies, such as improved materials and advances in computing, that later influenced civilian industries.
The author acknowledges that the program was expensive and that some innovations might have emerged eventually. However, the author argues that Apollo compressed decades of development into a shorter period by providing a clear goal and sustained funding. Therefore, the author concludes that Apollo should be understood as a catalyst for broader technological and organizational change, not only as a single historic event.
Answer: NASA reports describe repeated extreme-condition testing and documented redesigns that fostered rapid, accountable innovation.
This question tests ISEE Upper Level reading comprehension skills, specifically the ability to select evidence that supports a conclusion. In reading comprehension, identifying supporting evidence involves determining which details directly uphold the main argument or conclusion. This requires understanding the text's logical structure and the role of each piece of information. In the passage, the author presents the argument that Apollo accelerated innovation through systems, and provides evidence such as NASA reports on testing and redesigns. The correct answer, Choice A, is correct because it directly supports the author's conclusion by showing accountable progress. This choice aligns with the main argument by focusing on management impacts. Choice B is incorrect because it describes the landing without innovation links. This error often occurs when students choose iconic events over processes. To help students: Encourage them to map the argument structure and note how each piece of evidence fits. Practice identifying evidence that directly supports conclusions in various texts. Watch for: focusing on irrelevant details or opinions instead of logical support.
- Which of the following details strengthens the author's claim about practicing retrieval improving learning?
The author concludes that students learn more effectively when they practice retrieving information rather than repeatedly rereading notes. Although rereading can feel productive, it often creates an illusion of mastery because the material looks familiar. Retrieval practice, by contrast, forces the brain to reconstruct knowledge, revealing gaps that need attention. Therefore, the author argues that frequent low-stakes quizzes and self-testing are powerful study tools.
The passage describes a classroom experiment in which 2 groups studied the same science unit. One group spent extra time rereading the textbook, while the other group took short quizzes at the end of each lesson. A week later, both groups took a cumulative test that included questions requiring explanation, not just memorization. The quizzed group scored higher on average and was better at applying concepts to new examples.
The author adds that retrieval practice can feel harder, which may discourage students at first. However, this difficulty can be beneficial because it signals genuine mental effort. The author also notes that quizzes do not need to be graded harshly; the goal is feedback, not punishment. Consequently, the author concludes that students should replace some rereading time with structured self-testing.
Answer: The quizzed group later scored higher and applied concepts better on a cumulative test than the rereading group.
This question tests ISEE Upper Level reading comprehension skills, specifically the ability to select evidence that supports a conclusion. In reading comprehension, identifying supporting evidence involves determining which details directly uphold the main argument or conclusion. This requires understanding the text's logical structure and the role of each piece of information. In the passage, the author presents the argument that retrieval practice improves learning over rereading, and provides evidence such as the quizzed group's better test performance. The correct answer, Choice A, is correct because it directly supports the author's conclusion by showing higher scores and application in the quizzed group. This choice aligns with the main argument by contrasting methods' outcomes. Choice B is incorrect because it explains rereading's illusion without comparative data. This error often occurs when students choose explanatory mechanisms over experimental results. To help students: Encourage them to map the argument structure and note how each piece of evidence fits. Practice identifying evidence that directly supports conclusions in various texts. Watch for: focusing on irrelevant details or opinions instead of logical support.
- Which evidence best supports the argument that the agricultural revolution created significant social stratification that didn't exist in earlier societies?
Answer: Archaeological sites show evidence of elaborate burials for certain individuals alongside simple graves for others in agricultural communities.
When you encounter reading comprehension questions asking for "evidence that supports" a specific argument, you need to identify which choice provides the most direct, concrete proof of the claim being made.
The passage argues that agriculture created "significant social stratification" - meaning distinct social classes or hierarchies - that didn't exist in hunter-gatherer societies. Choice C provides the strongest evidence for this claim because elaborate versus simple burials directly demonstrate different treatment based on social status. Archaeological burial practices are one of the most reliable indicators of social hierarchy that researchers use, as societies typically reserve expensive, complex burial rituals for high-status individuals while giving simpler burials to common people.
Choice A is wrong because it only tells us where and when agriculture developed - this geographic and temporal information doesn't address social stratification at all. Choice B describes technological and structural advances (storage, housing, tools) but doesn't indicate different social classes; these could simply represent general improvements available to everyone. Choice D mentions resource accumulation, which could lead to inequality, but it's more of a potential cause rather than concrete evidence of actual social stratification.
Remember that evidence-based questions require you to distinguish between causes, effects, and direct proof. While choice D describes a mechanism that might create inequality, choice C shows the actual archaeological remains that prove different social classes existed. Look for the most concrete, observable evidence rather than theoretical explanations when questions ask what "best supports" an argument.
- Which piece of evidence from the passage best supports the conclusion that Colony Collapse Disorder has a complex, multi-factorial cause?
Answer: Recent studies suggest that CCD results from a complex interaction of multiple stressors rather than a single factor.
When you encounter reading comprehension questions asking for evidence that "best supports" a conclusion, you need to find the statement that most directly backs up the specific claim being made.
The conclusion states that Colony Collapse Disorder has a "complex, multi-factorial cause." Choice A directly supports this by explicitly stating that "recent studies suggest that CCD results from a complex interaction of multiple stressors rather than a single factor." This sentence uses nearly identical language to the conclusion—"complex interaction of multiple stressors" clearly indicates multi-factorial causation.
Choice B is incorrect because it only tells us when CCD was discovered and that it puzzled researchers. While being "puzzled" might suggest complexity, this doesn't provide evidence about multiple causes. Choice C is wrong because it discusses factors contributing to general bee population decline, not specifically to CCD. The passage treats CCD as a distinct phenomenon within the broader decline. Choice D mentions one specific theory about varroa mites, but discussing a single potential cause doesn't support the idea of multi-factorial causation—if anything, it points toward one factor.
The key trap here is confusing evidence about bee decline in general with evidence about CCD specifically. The passage clearly distinguishes between the broader environmental factors affecting all bees and the mysterious, complex phenomenon of CCD.
For ISEE reading questions, always match the scope of the evidence to the scope of the conclusion. If the question asks about a specific phenomenon, make sure your evidence directly addresses that phenomenon, not a broader category.
- Which piece of evidence best supports the author's main argument?
The author argues that Florence Nightingale's impact on medicine came as much from statistics as from bedside care. While she is often remembered for nursing wounded soldiers during the Crimean War (1853–1856), the author concludes that her most lasting contribution was persuading governments to reform sanitation through data. The passage explains that poor ventilation, contaminated water, and overcrowding caused preventable deaths in military hospitals.
The author cites Nightingale's reports to British officials after the war, which included carefully organized mortality figures. She used visual charts, including the famous "coxcomb" diagrams, to show that disease killed far more soldiers than battlefield injuries. Secondary historians quoted in the passage argue that these clear comparisons made it difficult for policymakers to ignore the problem. As reforms were implemented, hospital death rates declined, supporting the author's claim that data-driven advocacy produced measurable change.
The passage also notes that Nightingale's approach influenced later public health efforts. By treating sanitation as a matter of evidence and administration, she helped establish a model for reforms that could be evaluated. Therefore, the author concludes that Nightingale should be understood as a pioneer of applied statistics in service of human welfare.
Answer: Nightingale's charts showed disease killed more soldiers than injuries, and reforms were followed by declining death rates.
This question tests ISEE Upper Level reading comprehension skills, specifically the ability to select evidence that supports a conclusion. In reading comprehension, identifying supporting evidence involves determining which details directly uphold the main argument or conclusion. This requires understanding the text's logical structure and the role of each piece of information. In the passage, the author presents the argument that Nightingale's statistical advocacy reformed sanitation, and provides evidence such as charts showing disease deaths and subsequent declines. The correct answer, Choice B, is correct because it directly supports the author's conclusion by linking data to reforms and outcomes. This choice aligns with the main argument by emphasizing statistics' impact. Choice C is incorrect because it describes causes without reform evidence. This error often occurs when students select problems over solutions. To help students: Encourage them to map the argument structure and note how each piece of evidence fits. Practice identifying evidence that directly supports conclusions in various texts. Watch for: focusing on irrelevant details or opinions instead of logical support.
- Which evidence best supports the argument that extremophiles demonstrate life's potential to exist in previously unimaginable conditions?
Answer: These organisms have been discovered in environments previously thought to be completely inhospitable to any life forms.
When you encounter a reading comprehension question asking for "best evidence" to support an argument, you need to identify which choice most directly and comprehensively proves the main claim.
The argument here is that extremophiles show life can exist in "previously unimaginable conditions." Choice C perfectly captures this by stating that extremophiles "have been discovered in environments previously thought to be completely inhospitable to any life forms." This directly addresses the core idea that these discoveries have revolutionized our understanding of where life is possible—moving from "unimaginable" or "inhospitable" to reality.
Choice A provides a specific example of thermophiles surviving high temperatures, but it's just one type of extreme condition rather than evidence of the broader paradigm shift in thinking about life's possibilities. Choice B offers another specific example with radiation-resistant bacteria, but again focuses on just one extreme rather than the overall expansion of what we consider habitable. Choice D discusses the implications for finding life elsewhere, but this represents future possibilities rather than evidence of what extremophiles have already demonstrated about life's adaptability on Earth.
The key trap here is confusing specific examples with comprehensive evidence. While A and B provide compelling details about particular extremophiles, they don't capture the fundamental shift in scientific thinking that the question asks about. C encompasses the entire concept by emphasizing how these discoveries challenged previous assumptions about habitability.
Remember: when a question asks for evidence supporting a broad argument, look for the choice that addresses the argument's central premise rather than getting distracted by vivid but narrow examples.
- Which of the following details strengthens the author's claim about urban trees reducing summer heat?
The author argues that planting and maintaining urban trees is one of the most cost-effective strategies for reducing dangerous summer heat in cities. This conclusion rests on the idea that trees cool neighborhoods through shade and evapotranspiration, lowering surface and air temperatures. In many cities, heat is intensified by dark pavement and dense buildings, which absorb sunlight and release it slowly at night. Consequently, residents in areas with few trees often face higher health risks during heat waves.
To support the argument, the author cites a 2019 study comparing two nearby neighborhoods with similar building density but different canopy coverage. The neighborhood with greater tree canopy had notably cooler afternoon temperatures and fewer heat-related emergency calls. Additionally, satellite images showed that shaded streets had lower surface temperatures than adjacent unshaded blocks. These findings suggest that the cooling effect is not merely theoretical but measurable across real city landscapes.
Furthermore, the author notes that trees can reduce energy demand. When trees shade buildings, air conditioners run less frequently, which can lower electricity use during peak hours. Utility reports from several U.S. cities indicate that peak demand often occurs during the hottest afternoons, when grids are most stressed. By reducing demand at those times, trees can indirectly decrease the likelihood of power outages.
Critics sometimes claim that tree planting is too slow to address immediate heat threats. However, the author responds that cities can prioritize fast-growing species and protect existing mature trees, which provide the strongest cooling. Moreover, targeted planting in the hottest neighborhoods can improve equity by directing benefits to communities that face the greatest heat exposure. Therefore, while trees are not the only solution, the author concludes they are an essential component of a comprehensive heat strategy.
Answer: A 2019 comparison found cooler afternoons and fewer heat-related emergency calls in the higher-canopy neighborhood.
This question tests ISEE Upper Level reading comprehension skills, specifically the ability to select evidence that supports a conclusion. In reading comprehension, identifying supporting evidence involves determining which details directly uphold the main argument or conclusion. This requires understanding the text's logical structure and the role of each piece of information. In the passage, the author presents the argument that urban trees are a cost-effective way to reduce summer heat, and provides evidence such as the 2019 study comparing neighborhoods. The correct answer, Choice A, is correct because it directly supports the author's conclusion by providing measurable data on cooler temperatures and fewer emergencies in tree-covered areas. This choice aligns with the main argument by demonstrating real-world cooling effects. Choice B is incorrect because it describes heat intensification without linking to trees' benefits. This error often occurs when students select general background information instead of targeted support. To help students: Encourage them to map the argument structure and note how each piece of evidence fits. Practice identifying evidence that directly supports conclusions in various texts. Watch for: focusing on irrelevant details or opinions instead of logical support.
- What evidence most effectively supports the claim that volcanic eruptions can cause significant short-term global cooling?
Answer: The 1991 Mount Pinatubo eruption released 20 million tons of sulfur dioxide and reduced global temperatures by 0.5°C for two years.
When you encounter questions asking for the "best evidence" to support a claim, you need to distinguish between explanations of how something works versus concrete proof that it actually happened.
The claim here is that volcanic eruptions can cause "significant short-term global cooling." To support this claim effectively, you need specific, measurable evidence that demonstrates this cooling actually occurred, not just the theoretical mechanism behind it.
Choice B provides the strongest evidence because it gives you concrete, quantifiable data: Mount Pinatubo released a specific amount of sulfur dioxide (20 million tons) and caused a measurable temperature drop (0.5°C) for a defined time period (two years). This is direct proof that volcanic eruptions can indeed cause significant short-term cooling.
Choice A explains the mechanism of how cooling occurs but doesn't prove that significant cooling actually happens. It's the "how" but not the "evidence that it works." Choice C mentions dramatic consequences (crop failures, famine) but doesn't provide specific temperature data to quantify the cooling effect. Choice D discusses factors that influence climate effects but doesn't support the cooling claim at all—it's more about variability than evidence.
Remember on reading comprehension questions that ask for evidence: look for specific data, measurements, or documented outcomes rather than explanations of processes. The strongest evidence typically includes numbers, timeframes, and observable results that directly demonstrate the phenomenon in question.
- Which piece of evidence best supports the author's main argument?
The author argues that the success of the Montgomery Bus Boycott (1955–1956) depended on organized community networks as much as on a single dramatic moment. While Rosa Parks's arrest on December 1, 1955, is often highlighted, the author concludes that sustained planning, communication, and alternative transportation enabled the boycott to last more than a year. The passage emphasizes that leadership groups coordinated carpools, raised funds, and kept participants informed despite intimidation.
The author references primary sources, including meeting notes from local churches and announcements published in community newsletters. These records show scheduled pickup routes, volunteer driver lists, and collections for gasoline and vehicle repairs. Secondary historians cited in the passage argue that such logistical details transformed moral protest into a durable campaign. Without reliable transportation, many workers would have been forced to return to the buses quickly.
The passage also notes the legal outcome: in November 1956, the U.S. Supreme Court decision in Browder v. Gayle effectively ended bus segregation in Montgomery. However, the author maintains that the court ruling was reached only because the boycott endured long enough to keep national attention focused. Therefore, the author concludes that collective organization was the boycott's decisive strength.
Answer: Meeting notes and newsletters listed carpool routes and fundraising plans that kept the boycott functioning daily.
This question tests ISEE Upper Level reading comprehension skills, specifically the ability to select evidence that supports a conclusion. In reading comprehension, identifying supporting evidence involves determining which details directly uphold the main argument or conclusion. This requires understanding the text's logical structure and the role of each piece of information. In the passage, the author presents the argument that the boycott succeeded through organization, and provides evidence such as meeting notes on carpools and fundraising. The correct answer, Choice B, is correct because it directly supports the author's conclusion by showing logistical sustainment. This choice aligns with the main argument by emphasizing networks over single events. Choice C is incorrect because it highlights the initial arrest without ongoing support. This error often occurs when students focus on triggers over sustainers. To help students: Encourage them to map the argument structure and note how each piece of evidence fits. Practice identifying evidence that directly supports conclusions in various texts. Watch for: focusing on irrelevant details or opinions instead of logical support.
- Which evidence from the passage best supports the argument that jazz represented a fundamental break from European musical conventions?
Answer: Jazz emphasized improvisation and spontaneous musical conversation between performers rather than formal written structures.
When you encounter questions asking for evidence that "best supports" an argument, you need to identify which piece of evidence most directly proves the central claim. Here, the argument is that jazz represented a "fundamental break" from European musical conventions.
Choice A provides the strongest evidence because it establishes a direct contrast between jazz and European classical traditions. The passage explicitly states that classical music "relied heavily on written notation and formal structure" while jazz "emphasized improvisation and spontaneous musical conversation." This comparison shows the fundamental philosophical difference between the two musical approaches - one rigid and predetermined, the other fluid and creative in real-time.
Choice B is incorrect because while syncopated rhythms were innovative, this detail describes a specific technical element rather than proving a fundamental philosophical departure from European traditions. Choice C is wrong because geographic spread doesn't demonstrate how jazz differed from European conventions - it only shows where jazz traveled. Choice D fails because describing jazz's evolution into different formats doesn't prove it broke from European traditions; orchestral arrangements might actually suggest some similarity to European practices.
The key trap here is confusing supporting details with primary evidence. Choices B, C, and D all provide interesting information about jazz, but they don't directly contrast jazz with European musical traditions.
When you see "best supports" questions, look for the evidence that most directly addresses the specific claim being made. Often, the strongest evidence will contain explicit comparisons or contrasts that prove the argument rather than just describing related details.
- Read the passage, then answer: Which example from the text best illustrates the main idea?
In many novels, a character's private choices reveal broader themes about integrity. In Harper Lee's 1960 novel To Kill a Mockingbird, the author argues that Atticus Finch represents moral courage because he acts ethically even when his community disapproves. This courage is not shown through dramatic battles, but through steady decisions that carry social consequences.
First, Atticus agrees to defend Tom Robinson, a Black man falsely accused of assault, despite knowing the case is unpopular. He tells his daughter Scout that he could not "hold up [his] head in town" if he refused. This statement suggests that conscience, not applause, guides his actions.
Second, the narrative emphasizes that Atticus speaks to others with deliberate respect. He instructs Scout to consider life "from [another person's] point of view," urging empathy rather than quick judgment. In a tense community, this advice offers a disciplined alternative to anger.
Third, Atticus accepts that doing the right thing may not bring immediate success. During the trial, he presents evidence that challenges the accusation, yet the jury still convicts Tom. The outcome underscores the author's theme: moral courage can involve persistence without guaranteed victory.
Even outside the courtroom, Atticus remains consistent. When faced with criticism, he avoids retaliation and continues to model restraint. As a result, Scout learns that bravery can be quiet, principled, and difficult.
Therefore, the passage concludes that Atticus's character teaches readers a demanding definition of courage. True integrity, the author suggests, requires ethical action under pressure, not merely confident words.
Answer: Atticus says he could not hold up his head in town if he refused the defense.
This question tests ISEE Upper Level reading comprehension skills, specifically the ability to select evidence that supports a conclusion. In reading comprehension, identifying supporting evidence involves determining which details directly uphold the main argument or conclusion.

In the passage, the author presents the argument that Atticus Finch represents moral courage through ethical actions despite community disapproval, and provides evidence such as Atticus saying he couldn't hold up his head if he refused the defense. The correct answer, Choice A, is correct because it directly supports the author's conclusion by showing Atticus's personal ethical standard driving his decision to defend Tom Robinson despite unpopularity. This choice aligns with the main argument by demonstrating that conscience, not social approval, guides his actions. Choice C is incorrect because while it shows an unfair outcome, it doesn't illustrate Atticus's moral courage but rather the injustice he faces. This error often occurs when students select related information that doesn't directly support the specific claim. To help students: Encourage them to map the argument structure and note how each piece of evidence fits. Practice identifying evidence that directly supports conclusions in various texts. Watch for: focusing on irrelevant details or opinions instead of logical support.
- What evidence most strongly supports the conclusion that the placebo effect involves genuine physiological changes rather than just psychological perception?
Answer: Brain imaging studies reveal that placebo treatments can trigger endorphin release and activate the same neural pathways as medications.
When you encounter reading comprehension questions asking for evidence that "most strongly supports" a conclusion, you need to identify which piece of information provides the most direct, concrete proof of the claim being made.
The question asks what evidence best proves that placebo effects involve actual physiological changes, not just psychological perception. Answer choice A provides the strongest evidence because brain imaging studies offer objective, measurable proof of biological processes. When the passage states that "placebo treatments can trigger the release of endorphins and activate the same neural pathways as actual medications," this demonstrates real, observable changes in brain chemistry and function—not just patients feeling better psychologically.
Answer choice B describes how personal attention affects placebo strength, but this doesn't prove the changes are physiological rather than psychological. Answer choice C explains that treatment credibility influences placebo effects, which could still be explained by psychological factors alone—patients might simply feel better because they believe the treatment is more legitimate. Answer choice D discusses cultural expectations affecting responses, but again, this points more toward psychological influences rather than proving genuine biological changes.
The key distinction here is between correlation and direct evidence. While B, C, and D show factors that influence placebo effects, only A provides concrete biological evidence that measurable physiological processes are actually occurring.
For ISEE reading questions asking for "strongest evidence," always look for the most direct, objective proof rather than supporting details or correlational information.
- How does the evidence in paragraph 2 support the main conclusion?
The author argues that the printing press accelerated the spread of scientific ideas in early modern Europe by lowering costs and standardizing texts. Before widespread printing, scholars copied manuscripts by hand, and errors accumulated with each new copy. As a result, even careful readers could not be sure whether two versions of a text matched. The author concludes that printing made it easier for scientists to build on one another's work because they could consult the same information.
In paragraph 2, the author describes the publication of Nicolaus Copernicus's De revolutionibus in 1543 and later editions that circulated across universities. The passage notes that printed diagrams and tables could be reproduced consistently, allowing astronomers in different cities to compare calculations. Secondary historians cited by the author argue that this consistency reduced disputes caused by copying mistakes. Consequently, debates could focus more on evidence and less on which version of a diagram was accurate.
The author then acknowledges that printing also spread incorrect ideas, since printers sometimes favored popular works. However, the author maintains that the overall effect still supported scientific progress by enabling broader critique. When many readers had access to the same text, errors were more likely to be identified publicly. Therefore, the author concludes that printing's standardization was a crucial condition for cumulative science.
Answer: It shows that consistent printed tables let scholars compare calculations, reducing disputes caused by copying errors.
This question tests ISEE Upper Level reading comprehension skills, specifically the ability to select evidence that supports a conclusion. In reading comprehension, identifying supporting evidence involves determining which details directly uphold the main argument or conclusion. This requires understanding the text's logical structure and the role of each piece of information. In the passage, the author presents the argument that the printing press accelerated science through standardization, and provides evidence such as consistent tables reducing disputes. The correct answer, Choice A, is correct because it directly supports the author's conclusion by explaining how printing enabled reliable comparisons. This choice aligns with the main argument by highlighting standardization's benefits. Choice B is incorrect because it focuses on spreading errors, which counters the positive impact. This error often occurs when students select acknowledgments of flaws as main support. To help students: Encourage them to map the argument structure and note how each piece of evidence fits. Practice identifying evidence that directly supports conclusions in various texts. Watch for: focusing on irrelevant details or opinions instead of logical support.
- What evidence most strongly supports the conclusion that photosynthesis was responsible for Earth's major atmospheric transformation?
Answer: Initially released oxygen was absorbed by ocean iron, creating banded iron formations that geologists use as evidence for photosynthetic activity.
When you encounter questions asking for evidence that "most strongly supports" a conclusion, you're being tested on your ability to distinguish between different types of evidence and identify which provides the most direct, concrete proof.
The correct answer is C because banded iron formations represent physical, geological evidence that directly demonstrates photosynthesis occurred and produced oxygen. These formations show that oxygen was being produced (through photosynthesis) and then immediately absorbed by iron in the oceans, creating distinctive rock layers that scientists can still observe today. This is tangible proof that links photosynthetic activity to atmospheric change.
Let's examine why the other choices are weaker evidence: A describes Earth's atmospheric conditions before photosynthesis but doesn't prove that photosynthesis caused the change—it only establishes the starting point. B explains the biochemical process of photosynthesis but doesn't provide evidence that this process actually occurred on a scale large enough to transform the atmosphere. D describes the consequences of atmospheric change (the oxygen catastrophe) but doesn't directly prove that photosynthesis was the cause—other factors could theoretically have produced similar effects.
Remember that "evidence" questions require you to identify concrete, observable proof rather than descriptions of processes or effects. Look for answer choices that describe physical traces, measurable data, or direct observations that scientists can point to as proof. The strongest evidence is usually something tangible that can be studied and verified, like the geological formations mentioned in choice C.
- Read the passage, then answer: Which of the following details strengthens the author's claim about urban trees?
Many city planners now argue that planting and protecting urban trees is a practical way to improve everyday life. Their central argument is that trees do more than beautify streets; they can lower surface temperatures, reduce stormwater runoff, and support public well-being. Because cities often contain large areas of pavement and dark roofs, they can heat up quickly during warm months.
First, trees provide shade, which can reduce how much sunlight reaches sidewalks and building walls. When less solar energy is absorbed by concrete and asphalt, nearby air temperatures can drop. In addition, trees release water vapor through transpiration, a natural process that can further cool the surrounding area.
Second, trees can help manage heavy rain. Leaves and branches slow falling water, and roots absorb moisture that might otherwise rush into storm drains. Therefore, neighborhoods with more tree cover may experience fewer problems from sudden downpours, especially when drainage systems are old or undersized.
Public health researchers also study how green spaces affect people. Several surveys report that residents living near trees and parks describe lower stress and greater satisfaction with their neighborhoods. While these surveys cannot prove that trees alone cause happiness, they do suggest a meaningful connection between greenery and well-being.
City forestry programs, however, require planning. Young trees need watering, and older trees require pruning to remain safe. For that reason, the author concludes that urban tree policies should be treated as essential infrastructure, not as optional decoration.
Overall, the passage argues that urban trees provide measurable environmental benefits and deserve consistent funding. The author emphasizes that long-term maintenance is necessary, but the advantages can extend across entire communities.
Answer: Trees can lower temperatures through shade and transpiration, reducing heat absorbed by pavement.
This question tests ISEE Upper Level reading comprehension skills, specifically the ability to select evidence that supports a conclusion. In reading comprehension, identifying supporting evidence involves determining which details directly uphold the main argument or conclusion. This requires understanding the text's logical structure and the role of each piece of information. In the passage, the author presents the argument that urban trees provide practical benefits beyond beautification by lowering temperatures, reducing stormwater runoff, and supporting well-being, and provides evidence such as trees providing shade and releasing water vapor through transpiration. The correct answer, Choice A, is correct because it directly supports the author's conclusion by explaining the specific mechanisms (shade and transpiration) through which trees lower urban temperatures. This choice aligns with the main argument by providing scientific explanation for the claimed benefits. Choice B is incorrect because it focuses on aesthetic preferences rather than practical environmental benefits. This error often occurs when students select details that are tangentially related but don't support the main claim. To help students: Encourage them to map the argument structure and note how each piece of evidence fits. Practice identifying evidence that directly supports conclusions in various texts. Watch for: focusing on irrelevant details or opinions instead of logical support.
- Read the passage, then answer: How does the evidence in paragraph 4 support the main conclusion?
The U.S. National Park idea is often praised as a decision that protected landscapes for future generations. The author's central argument is that early park policies, though imperfect, created a lasting model for conservation by setting aside land under federal protection. This model influenced later environmental planning by showing that preservation could be a public responsibility.
The passage points to Yellowstone, established in 1872, as an early example of this approach. Congressional debates and newspaper articles from the time describe the park as a place of unusual natural features that should not be sold for private development. Although tourism was expected, the key decision was to keep the land in public hands.
Next, the author explains that the park system expanded over time. Yosemite became a national park in 1890, and other sites followed. Secondary sources, such as historians' summaries, argue that each new park strengthened the precedent that certain places could be protected by law.
In paragraph 4, the author cites the Organic Act of 1916, which created the National Park Service. The law directed the agency to conserve scenery and wildlife while allowing public enjoyment in ways that would leave parks "unimpaired" for the future. This wording provided a clear standard that managers could apply across many different parks.
The passage acknowledges that early policies sometimes excluded Indigenous communities and ignored their land claims. Nevertheless, the author maintains that the legal framework for preservation endured and later reforms attempted to address earlier harms.
Ultimately, the author concludes that the national park system shaped conservation by institutionalizing preservation. Even with serious limitations, the early laws and agencies established an enduring structure that later generations could improve.
Answer: It gives a legal standard—keeping parks "unimpaired"—that institutionalized preservation across many sites.
This question tests ISEE Upper Level reading comprehension skills, specifically the ability to select evidence that supports a conclusion. In reading comprehension, identifying supporting evidence involves determining which details directly uphold the main argument or conclusion. This requires understanding the text's logical structure and the role of each piece of information. In the passage, the author presents the argument that early park policies created a lasting model for conservation by institutionalizing preservation, and provides evidence such as the Organic Act establishing legal standards for park management. The correct answer, Choice A, is correct because it directly supports the author's conclusion by showing how the Organic Act provided a legal framework (keeping parks "unimpaired") that could be applied systematically across many sites. This choice aligns with the main argument by demonstrating how preservation became institutionalized through law. Choice B is incorrect because it misinterprets the evidence - tourism was expected but not the primary purpose, and this doesn't support the institutionalization argument. This error often occurs when students misread the relationship between evidence and conclusion. To help students: Encourage them to map the argument structure and note how each piece of evidence fits. Practice identifying evidence that directly supports conclusions in various texts. Watch for: focusing on irrelevant details or opinions instead of logical support.
- What evidence most effectively supports the claim that mirror neurons play a fundamental role in social understanding and empathy?
Answer: Children with autism, who struggle with social interaction and empathy, show reduced mirror neuron activity compared to neurotypical children.
When you encounter questions asking for evidence that "most effectively supports" a claim, you need to distinguish between basic descriptions and compelling proof. The claim here is that mirror neurons are fundamental to social understanding and empathy.
The strongest evidence comes from comparing populations with different social abilities. Choice B provides this by showing that children with autism—who have documented difficulties with social interaction and empathy—demonstrate reduced mirror neuron activity compared to neurotypical children. This correlation between impaired social function and decreased mirror neuron activity strongly suggests these neurons are crucial for social understanding.
Choice A simply describes what mirror neurons do (firing during both action and observation) but doesn't prove they're fundamental to empathy—it's just basic functionality. Choice C about musicians shows mirror neurons can be enhanced through experience, but this relates more to skill development than to proving their role in empathy and social understanding. Choice D mentions researchers' proposals about cultural learning and language, but these are theoretical suggestions rather than evidence.
The key difference is that B provides comparative evidence: when social abilities are impaired (autism), mirror neuron activity is also reduced. This type of correlation offers much stronger support for the claim than basic descriptions of function or theoretical proposals.
Remember that on reading comprehension questions asking for "evidence that supports," look for data that shows relationships or comparisons rather than simple definitions or hypotheses. The most convincing evidence often comes from studying what happens when the system doesn't work normally.
