SSAT Middle Level: Reading › Supporting Evidence
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?
Many students enjoy experiments that make loud sounds when items land.
The objects fall faster from higher places because they travel farther.
Both objects hit the floor at nearly the same time when dropped together.
Air resistance proves gravity only works on light objects in classrooms.
Explanation
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.
Read this current events report: A city library launches a “Read and Repair” program in 2025. The main idea is that libraries can support community learning beyond books. The program offers free weekly workshops on fixing small items like torn backpacks. In the first month, 120 residents attend, and 45 items get repaired. Maya, a librarian, says, “We are teaching skills people can use right away” (City Library News, 2025). A local teacher adds that students practice problem-solving when they mend things. The report also notes the library extends Saturday hours. What evidence does the author use to support the main idea?
Some residents think workshops are less useful than borrowing new items.
In the first month, 120 residents attend, and 45 items get repaired.
Libraries have always been quiet places for reading and studying.
The library extends Saturday hours to help families visit more often.
Explanation
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 main idea that libraries can support community learning beyond books through the "Read and Repair" program. Choice A is correct because it provides direct evidence that 120 residents attended and 45 items were repaired, demonstrating concrete community learning outcomes beyond traditional book services. Choice B is incorrect because extending Saturday hours relates to general library access rather than specifically supporting the idea of learning beyond books. To help students: Teach strategies for identifying key ideas and associated evidence, such as looking for specific examples and statistics that demonstrate the main claim. Practice distinguishing between general library improvements and evidence that specifically supports expanded learning services.
Which evidence best supports the claim that the Titanic's design was considered very safe?
The ship sank completely in less than three hours after the collision occurred.
The steel plates became brittle in freezing waters and cracked upon impact.
Engineers believed the ship could survive flooding in up to four compartments simultaneously.
The collision with the iceberg created openings in five separate watertight compartments.
Explanation
Choice C best supports the safety claim because it shows the engineers' confidence in the design's ability to survive significant damage (flooding in four compartments). This demonstrates why the ship was considered very safe. Choice A describes the sinking, which contradicts safety claims. Choice B describes the actual damage that caused the sinking. Choice D explains a design flaw that contributed to the disaster.
What evidence best supports the statement that the Library of Alexandria was "one of the greatest centers of learning"?
The library was located near the Mediterranean Sea in northern Africa.
The library was built in Egypt around 295 BCE during ancient times.
The library's decline began in the 3rd century and ended in the 7th century.
Scholars from across the Mediterranean region came there specifically to study.
Explanation
Choice C provides the best evidence because scholars traveling from across the Mediterranean specifically to study there demonstrates the library's reputation as a center of learning. Choice A only gives construction details. Choice B describes the library's decline, not its greatness. Choice D merely provides geographical information without supporting the claim about learning.
What evidence best supports the claim that exercise provides "numerous benefits for mental health"?
People who exercise regularly report lower levels of anxiety and depression than sedentary individuals.
Group fitness activities provide valuable social interaction and community support for all participants.
Physical activity releases endorphins, which are natural mood-improving chemicals in the brain.
Exercise improves sleep quality, which contributes to enhanced mental well-being and health overall.
Explanation
Choice B provides the strongest evidence for numerous mental health benefits by comparing exercisers to non-exercisers and showing measurable improvements in anxiety and depression. Choice A explains one mechanism (endorphins) but doesn't demonstrate multiple benefits. Choice C focuses on one specific benefit (social interaction) rather than numerous benefits. Choice D mentions one benefit (sleep improvement) but doesn't show the range of mental health benefits.
What evidence best supports the conclusion that wolves are crucial for healthy ecosystems?
Multiple positive changes occurred throughout the park after wolves returned to the ecosystem.
The wolf population effectively controlled and reduced the number of elk in the area.
Returning vegetation helped prevent soil erosion and improved the water quality significantly.
Wolves were successfully reintroduced to Yellowstone National Park in 1995.
Explanation
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.
Read this science explanation: Earth’s seasons happen because Earth’s axis tilts about 23.5 degrees. The main idea is that tilt changes sunlight angle and day length during the year. When the Northern Hemisphere tilts toward the Sun, it gets more direct sunlight and longer days. Yuki measures shadows at noon in June and December and finds the December shadow is much longer. A space science guide notes, “The tilt, not distance from the Sun, causes seasons” (European Space Agency, 2022). The passage adds that both hemispheres have opposite seasons at the same time. Which quote provides the strongest evidence that distance is not the main cause of seasons?
Many people feel summer is warmer, so the Sun must be closer then.
Yuki measures shadows at noon and notices they change between months.
Both hemispheres have opposite seasons at the same time during the year.
“The tilt, not distance from the Sun, causes seasons” (European Space Agency, 2022).
Explanation
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 Earth's tilt causes seasons and asks for evidence that distance from the Sun is not the main cause. Choice A is correct because it provides a direct quote from a space science guide explicitly stating "The tilt, not distance from the Sun, causes seasons," which directly addresses and refutes the distance misconception. Choice C is incorrect because while it mentions opposite seasons in different hemispheres, it doesn't explicitly address why distance isn't the cause. To help students: Teach strategies for identifying key ideas and associated evidence, such as looking for authoritative quotes that directly address common misconceptions. Practice distinguishing between evidence that implies a conclusion versus evidence that explicitly states it.
Which evidence from the passage best supports the claim that monarch butterfly migration is "remarkable"?
The butterflies are orange and black in color and travel during fall season.
The butterflies use the sun's position to help them navigate during their journey.
The migrating butterflies have never been to their destination before in their lives.
Scientists have studied these butterflies and their navigation methods extensively.
Explanation
Choice B provides the strongest evidence for why the migration is remarkable—the fact that butterflies navigate to a place they've never been before is truly extraordinary. Choice A merely describes physical characteristics and timing. Choice C mentions scientific study but doesn't explain what makes the migration remarkable. Choice D describes navigation methods but doesn't emphasize the remarkable nature of the journey.
What evidence from the passage best supports the claim that the immune system is "remarkably effective at protecting the body"?
The immune system has a sophisticated memory for previously encountered threats.
Vaccines work by training the immune system to recognize dangerous pathogens safely.
After recovering from illness, people often receive lifelong protection against that disease.
White blood cells patrol the bloodstream and identify foreign invaders like bacteria.
Explanation
Choice C provides the strongest evidence of remarkable effectiveness—lifelong protection after one encounter demonstrates the immune system's powerful and lasting protective abilities. Choice A describes immune function but not effectiveness. Choice B explains memory capabilities but doesn't demonstrate protection effectiveness. Choice D describes how vaccines work but doesn't prove the immune system's natural effectiveness.
Which evidence best supports the claim that Pompeii provides "unique insights into daily Roman life"?
Archaeologists have been studying and excavating the site for many years now.
The volcanic ash preserved the shapes of people and animals in their final moments.
Complete houses with furniture still in place and bread still in bakery ovens were found.
Mount Vesuvius erupted in 79 CE and buried the entire city under volcanic ash.
Explanation
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.
