- What evidence best supports the statement that the Great Depression was "the most severe economic downturn in modern American history"?
Answer: Unemployment rose from 3% to 25% between 1929 and 1933.
Choice B provides the strongest statistical evidence of severity—unemployment jumping from 3% to 25% represents an unprecedented economic collapse affecting one in four Americans. Choice A shows the human impact but doesn't quantify the severity. Choice C describes banking failures but doesn't provide comparative data. Choice D shows industrial decline but doesn't demonstrate this was the most severe downturn in history.
- What evidence best supports the claim that antibiotics have "saved millions of lives"?
Answer: Antibiotics helped treat wounded soldiers during World War II and dramatically reduced deaths from infections.
Choice C provides the most direct evidence of lives saved by showing concrete results—antibiotics dramatically reduced deaths from infected wounds among soldiers. This demonstrates measurable life-saving impact. The other choices either describe the discovery process, conditions before antibiotics, or current benefits, but don't provide specific evidence of the millions of lives saved.
- Which evidence from the passage best demonstrates that dolphins are "among the most intelligent animals on Earth"?
Answer: They demonstrate self-awareness by recognizing themselves in mirrors like great apes and elephants do.
Choice C provides the strongest evidence of high intelligence because self-awareness is an extremely rare cognitive ability shared only with the most intelligent animals (great apes and elephants). This places dolphins in elite company. The other choices show impressive abilities but don't demonstrate the exceptional level of intelligence suggested by the phrase "among the most intelligent."
- Which evidence most effectively supports the claim that musical structure, rather than simple repetition, creates earworms?
Answer: Participants reported earworms most frequently after hearing songs with moderate complexity
When you encounter a question asking for evidence that supports a specific claim, you need to identify which piece of information most directly proves that particular point, not just relates to the general topic.
The passage claims that musical structure, rather than simple repetition, creates earworms. Choice C provides the strongest evidence because it shows that songs of "moderate complexity" - those that are "simple enough to remember but sophisticated enough to surprise" - most frequently become earworms. This directly demonstrates that structural sophistication matters more than basic repetition, since purely repetitive songs would be simple but not surprising.
Choice A describes how unexpected progressions followed by familiar resolutions create cognitive itch, but this explains the mechanism rather than providing evidence that structure trumps repetition. Choice B explains how our brains process musical patterns, which is background information about the process rather than evidence comparing structure to repetition. Choice D shows that musical training affects earworm experiences, but this finding about individual differences doesn't directly support the claim about what makes songs sticky in the first place.
The key distinction is between explanation and evidence. While A and B explain how musical structure works in our brains, only C provides concrete research findings that prove structure matters more than simple repetition by showing that moderately complex songs are most effective.
On reading comprehension questions about evidence and support, look for the choice that most directly proves the specific claim being made, rather than choices that simply relate to or explain the topic.
- Read this science explanation: Gravity is a force that pulls objects toward each other. The main idea is that gravity acts on all objects with mass, even when we do not notice it. In a simple test, Keisha drops a tennis ball and a textbook from the same height. Both hit the floor at nearly the same time, though air resistance slows the lighter ball slightly. A scientist explains, "On Earth, gravity gives all objects the same acceleration if air effects are small" (NASA, 2023). The passage adds that the objects fall faster from higher places. Which detail from the passage supports the conclusion that gravity affects different objects similarly?
Answer: Both objects hit the floor at nearly the same time when dropped together.
This question tests SSAT Middle Level skills in selecting evidence to support a given answer. The ability to identify supporting evidence involves recognizing details that directly affirm the main idea or specific claims within a text. In this passage, the author explains that gravity acts on all objects with mass and asks for evidence that gravity affects different objects similarly. Choice A is correct because it provides direct evidence that both a tennis ball and textbook hit the floor at nearly the same time when dropped, demonstrating that gravity affects objects of different masses in similar ways. Choice B is incorrect because it offers information about falling speed from different heights, which doesn't address how gravity affects different objects similarly. To help students: Teach strategies for identifying key ideas and associated evidence, such as looking for experimental results that directly demonstrate scientific principles. Practice distinguishing between evidence that supports the specific claim versus general information about the topic.
- What evidence best supports Rodriguez's argument that native language maintenance enhances rather than interferes with English acquisition?
Answer: Students in maintenance programs scored higher on English standardized tests by middle school
When you encounter reading questions about scientific arguments, focus on distinguishing between evidence (concrete data) and explanations (theories about why the data exists). The question asks what evidence "best supports" Rodriguez's argument, so you need actual measurable results, not just methodology or reasoning.
Rodriguez argues that maintaining native language skills enhances English learning rather than interfering with it. The strongest evidence for this claim comes from the concrete test results: students in maintenance programs scored higher on English standardized tests by middle school (A). This directly contradicts the assumption that native language use hurts English acquisition—if that assumption were true, these students should have scored lower, not higher. The fact that they outperformed peers in English-only programs provides measurable proof of Rodriguez's theory.
Let's examine why the other choices don't work as well. Choice (B) describes the study's methodology (tracking 500 students over eight years), which establishes credibility but isn't evidence for the specific argument about language maintenance. Choice (C) presents the negative outcome for transitional programs, which supports part of Rodriguez's findings but doesn't directly prove that native language maintenance helps English acquisition. Choice (D) offers Rodriguez's theoretical explanation for why the pattern exists, but this is her interpretation of the evidence, not the evidence itself.
Remember: on reading comprehension questions about research studies, distinguish between the data (what researchers observed) and the conclusions (what they think the data means). Evidence questions typically want the observable results, not the researcher's explanations.
- Which piece of evidence best supports the claim that Petra's deterioration is accelerating due to human activity rather than natural causes alone?
Answer: The fact that over one million visitors annually has accelerated structural deterioration
When you encounter a question asking for evidence that supports a specific claim, you need to identify which piece of information directly proves the stated cause-and-effect relationship. Here, you're looking for evidence that human activity, not just natural forces, is accelerating Petra's deterioration.
Choice B provides the strongest evidence because it explicitly connects human activity (over one million annual visitors) to accelerated structural deterioration. This directly demonstrates that human presence is causing faster damage than would occur naturally, making it the best support for the claim about human-caused acceleration.
Let's examine why the other choices don't work as well. Choice A describes climate change causing flash floods, but this represents a natural phenomenon rather than direct human activity at the site. While climate change has human origins globally, the rainfall and floods themselves are natural processes. Choice C gives Dr. Chen's timeline warning about potential loss, but this is a prediction about future consequences rather than evidence of current human-caused acceleration. Choice D mentions UNESCO's threat, which is a response to the deterioration problem but doesn't provide evidence about what's causing the acceleration.
The key strategy here is to distinguish between evidence of the problem itself versus evidence of its specific cause. When a question asks you to support a claim about causation, look for the choice that most directly links the proposed cause (human activity) to the stated effect (accelerated deterioration). Don't get distracted by responses to the problem or related but indirect evidence.
- Which evidence from the passage best supports the claim that the telescope "revolutionized astronomy"?
Answer: Galileo's discoveries challenged existing beliefs about the cosmos and universe.
Choice C provides the best evidence for revolution in astronomy—challenging existing beliefs about the cosmos demonstrates a fundamental transformation in the field. Choice A gives the timeline but not the revolutionary impact. Choice B describes one specific discovery but not the revolutionary nature. Choice D mentions an important discovery but doesn't emphasize how it revolutionized the entire field of astronomy.
- Which evidence best supports the claim that Pompeii provides "unique insights into daily Roman life"?
Answer: Complete houses with furniture still in place and bread still in bakery ovens were found.
Choice B provides the best evidence for unique insights into daily life—finding houses with furniture in place and bread in ovens shows perfectly preserved everyday activities. Choice A explains how the preservation occurred but not what insights it provides. Choice C describes preserved human and animal shapes but focuses on death rather than daily life. Choice D mentions ongoing study but doesn't specify what unique insights were gained.
- Which evidence best demonstrates the effectiveness of the Underground Railroad network?
Answer: An estimated 100,000 people successfully escaped slavery through these routes between 1810 and 1850.
Choice C provides the most concrete evidence of effectiveness—the specific number of 100,000 successful escapees over 40 years demonstrates the network's success quantitatively. Choice A describes the method but not the results. Choice B clarifies the name but doesn't show effectiveness. Choice D explains the roles of helpers but doesn't quantify the success rate.
- Read this science explanation: Photosynthesis lets plants make sugar using light, water, and carbon dioxide. The main idea is that light intensity affects how fast photosynthesis happens. In a classroom test, Jamal puts pondweed under lamps. He counts oxygen bubbles for one minute at different distances. At 10 cm, he counts 28 bubbles; at 20 cm, 17 bubbles; at 30 cm, 9 bubbles. A textbook states, "More light energy can drive more reactions, up to a limit" (National Geographic Society, 2020). The passage adds that temperature stayed the same during the test. Which detail from the passage supports the conclusion that brighter light increases photosynthesis?
Answer: At 10 cm, Jamal counts 28 bubbles, but only 9 bubbles at 30 cm.
This question tests SSAT Middle Level skills in selecting evidence to support a given answer. The ability to identify supporting evidence involves recognizing details that directly affirm the main idea or specific claims within a text. In this passage, the author presents the conclusion that brighter light increases photosynthesis, and the experiment measures oxygen bubble production at different distances from a light source. Choice A is correct because it provides direct evidence showing that bubble count decreases as distance from light increases (28 bubbles at 10 cm versus 9 bubbles at 30 cm), demonstrating the relationship between light intensity and photosynthesis rate. Choice D is incorrect because while it mentions temperature control, it illogically concludes that light couldn't affect bubble counts, contradicting the experimental results. To help students: Teach strategies for identifying key ideas and associated evidence, such as looking for numerical data that supports scientific conclusions. Practice distinguishing between experimental results and background information in scientific texts.
- Which piece of evidence best supports the conclusion that Maria's hypothesis was incorrect?
Answer: Plants under red light averaged 8.2 inches while blue light plants averaged 6.4 inches.
Choice B provides the concrete numerical evidence that contradicts Maria's hypothesis—the red light plants grew taller than the blue light plants, opposite to her prediction. Choice A shows her methodology was sound but doesn't prove the hypothesis wrong. Choice C gives timing information but no evidence about the hypothesis. Choice D shows Maria's attitude toward the results but doesn't provide the supporting evidence.
- What evidence best supports the conclusion that wolves are crucial for healthy ecosystems?
Answer: Multiple positive changes occurred throughout the park after wolves returned to the ecosystem.
Choice D provides the best evidence because it encompasses the chain reaction of positive ecosystem changes that resulted from wolf reintroduction, demonstrating their crucial role. Choice A simply states the reintroduction fact. Choice B describes one specific effect (elk control) but not the broader ecosystem impact. Choice C mentions specific benefits but doesn't connect them to the wolves' crucial role.
- What evidence best supports the claim that rising ocean temperatures harm coral reefs?
Answer: When temperatures rise 2-3 degrees above normal, corals become stressed and turn white.
Choice C provides the most direct evidence linking temperature rises to coral harm—it specifies the exact temperature increase that causes coral stress and visible damage (turning white). Choice A gives examples of bleaching events but doesn't explain the temperature connection. Choice B describes normal coral conditions but not the harm. Choice D makes a general statement about climate change but doesn't specifically link temperature to harm.
- What evidence best supports the conclusion that teenagers have different natural sleep patterns than adults?
Answer: Melatonin hormone is released two hours later in teenagers compared to adults.
Choice C provides the most direct biological evidence for different sleep patterns—the delayed release of melatonin explains why teenagers naturally stay up and wake up later. Choice A shows academic benefits of later start times but doesn't explain the biological difference. Choice B describes the study methodology but not the findings about sleep patterns. Choice D shows behavioral benefits but doesn't address the natural sleep pattern differences.
- Which evidence from the passage best supports the claim that Amelia Earhart was a "pioneering aviator"?
Answer: She became the first woman to fly solo across the Atlantic Ocean in 1932.
Choice B provides the strongest evidence of pioneering achievements—being the first woman to accomplish a major aviation milestone demonstrates she was breaking new ground. Choice A describes her disappearance but not her pioneering accomplishments. Choice C shows her advocacy work but not specifically her aviation pioneering. Choice D gives flight details but doesn't emphasize the pioneering nature of the achievement.
- What evidence from the passage best supports the statement that honeybees are "essential pollinators"?
Answer: Honeybees pollinate approximately one-third of everything humans eat for food.
Choice C provides the strongest evidence of essential status—pollinating one-third of human food directly demonstrates how crucial honeybees are to our food supply. Choice A describes their work ethic but not their essential role. Choice B shows their activity level but not their essential nature. Choice D describes consequences of pollinator loss but doesn't specifically emphasize honeybees' essential role.
- Which evidence best supports the conclusion that wolf reintroduction had indirect effects beyond simply controlling deer populations?
Answer: Increased vegetation stabilized riverbanks and changed stream channel geography
When you encounter reading comprehension questions about "evidence that supports a conclusion," you need to distinguish between direct effects and indirect, cascading consequences that extend far beyond the initial change.
The correct answer is D because it describes the most removed, indirect consequence of wolf reintroduction. The passage traces a complex chain: wolves changed deer behavior → vegetation recovered → this led to riverbank stabilization and altered stream geography. This physical transformation of the landscape represents the furthest-reaching indirect effect mentioned, demonstrating how predator reintroduction can reshape entire ecosystems in unexpected ways.
Let's examine why the other choices don't work as well. Choice A simply states a historical fact about when wolves returned—this provides context but doesn't demonstrate indirect effects. Choice B describes what scientists initially expected, which actually represents the most direct effect possible (wolves eating deer), not indirect consequences. Choice C describes an important intermediate step where wolves changed deer behavior, but this behavioral change, while significant, is still relatively direct compared to the complete geographical transformation of waterways.
The key distinction is that choice D represents the end result of multiple cascading effects—wolves affecting deer, deer changes affecting plants, plant recovery affecting beavers, and beaver activity ultimately reshaping the physical landscape itself.
For reading comprehension questions asking for the "best evidence," look for the choice that most completely fulfills the specific criteria mentioned in the question. Here, "indirect effects beyond simply controlling deer populations" points you toward the most far-removed consequence in the ecological chain.
- Which evidence from the passage best supports the claim that video games can have "positive effects on cognitive development"?
Answer: Action video games improve visual attention and spatial reasoning skills in players.
Choice C provides the most direct evidence of positive cognitive effects—specifically mentioning improved visual attention and spatial reasoning skills demonstrates cognitive development benefits. Choice A gives recommendations but doesn't provide evidence of positive effects. Choice B mentions that research exists but doesn't state the positive findings. Choice D describes multiplayer coordination but doesn't explicitly connect it to cognitive development.
- What evidence from the passage most strongly supports calling the platypus "one of the world's strangest animals"?
Answer: The platypus is a mammal that lays eggs, which only one other mammal species does.
Choice B provides the strongest evidence because being a mammal that lays eggs is extremely unusual—only two mammal species in the world do this. This biological anomaly makes the platypus genuinely strange. Choice A mentions habitat but not strange characteristics. Choice C describes a practical adaptation that's not particularly strange. Choice D describes unusual physical features but they're less remarkable than the egg-laying trait.
