Supporting A ClaimQuestion 1 of 20

(1) The Roman Empire was renowned for its impressive engineering feats, but perhaps none were as vital as its aqueducts. (2) These structures were designed to transport fresh water from distant sources into cities and towns. (3) The true brilliance of the aqueducts lay in their use of a precise, continuous gradient. (4) By maintaining a slight downward slope over many miles, engineers harnessed the power of gravity to ensure a constant flow of water without the need for pumps. (5) This reliable water supply was essential for public baths, fountains, and sanitation, contributing significantly to Roman public health.

The author's claim in sentence 3 about the 'true brilliance' of the aqueducts is best supported by which sentence?

Sentence 1 makes a general statement about the Roman Empire's engineering skills.

Sentence 2 states the basic purpose of the aqueducts as water transportation systems.

Sentence 5 lists the various public amenities that the aqueducts' water supply made possible.

Sentence 4 explains how the use of a slight, consistent slope allowed for a pump-free system.

Question 1

The author's claim in sentence 3 about the 'true brilliance' of the aqueducts is best supported by which sentence?

Sentence 1 makes a general statement about the Roman Empire's engineering skills.
Sentence 2 states the basic purpose of the aqueducts as water transportation systems.
Sentence 5 lists the various public amenities that the aqueducts' water supply made possible.
Sentence 4 explains how the use of a slight, consistent slope allowed for a pump-free system. (correct answer)

Explanation: When you encounter questions asking which sentence "best supports" an author's claim, you need to identify what specific evidence directly backs up that claim. The author claims the "true brilliance" of Roman aqueducts was their "precise, continuous gradient." The correct answer is D because sentence 4 provides the concrete explanation of why this gradient was so brilliant. It shows how maintaining "a slight downward slope over many miles" allowed engineers to "harness the power of gravity to ensure a constant flow of water without the need for pumps." This directly explains what made the gradient system so ingenious—it was a pump-free solution that worked reliably across vast distances. Looking at the wrong answers: A is too general, discussing Roman engineering broadly rather than specifically supporting the gradient claim. B only describes the basic function of aqueducts (transporting water) without explaining what made their design brilliant. C focuses on the end results and benefits of having water supply, but doesn't address why the gradient system itself was clever. The key trap here is confusing related information with supporting evidence. Sentences 1, 2, and 5 all relate to aqueducts, but only sentence 4 actually explains and supports the specific claim about the gradient's brilliance. For SHSAT reading questions about textual support, always ask yourself: "Which piece of evidence directly explains or proves this specific claim?" Look for the sentence that provides the reasoning or mechanism behind the author's assertion, not just related background information.

Question 2

(1) In 1932, Australia faced an unusual opponent in what became known as the 'Great Emu War.' (2) A massive population of 20,000 emus migrated into the farming district of Campion in Western Australia after their breeding season. (3) The birds were causing widespread destruction, destroying crops and damaging fences. (4) In response, the military was deployed with machine guns to cull the emu population. (5) However, the emus proved to be surprisingly difficult targets, often scattering into small groups and outmaneuvering the soldiers, leading to a largely unsuccessful and widely ridiculed campaign.

Which sentence best supports the claim that the military campaign against the emus was 'largely unsuccessful' (sentence 5)?

Sentence 1 introduces the historical event and gives it a formal name.
Sentence 3 describes the extent of the damage caused by the emus to local farms.
Sentence 4 explains the official response taken by the government to address the problem.
Sentence 5 describes the emus' effective tactics and their ability to evade the soldiers. (correct answer)

Explanation: When you encounter a question asking which sentence "best supports" a specific claim, you need to look for evidence that directly proves or demonstrates that claim. The claim here is that the military campaign was "largely unsuccessful." The correct answer is D because sentence 5 provides concrete evidence of the campaign's failure. It explains exactly why the military efforts didn't work: the emus were "surprisingly difficult targets" that could "scatter into small groups" and "outmaneuver the soldiers." This directly demonstrates the unsuccessful nature of the campaign by showing how the emus consistently defeated the military's tactics. Let's examine why the other choices don't work. Choice A merely introduces the historical event and gives it a name, but doesn't provide any evidence about success or failure. Choice B describes the problem that prompted the military response (crop destruction and fence damage), but this actually happened before the campaign began, so it can't support claims about the campaign's results. Choice C explains what the government decided to do (deploy military with machine guns), but describing the response doesn't tell us whether that response was effective or not. On reading comprehension questions like this, always distinguish between sentences that describe the problem, the attempted solution, and the actual results. Only evidence about results can support claims about success or failure. Look for specific details that directly prove the claim rather than sentences that merely provide background information or describe the initial situation.

Question 3

(1) Cartography, the art and science of map-making, has a long and complex history. (2) Early maps were often more artistic than accurate, reflecting the philosophical or religious beliefs of their creators rather than precise geography. (3) A significant turning point came with the Age of Exploration in the 15th and 16th centuries. (4) As mariners charted new coastlines and trade routes, there was a growing demand for maps that were navigationally precise. (5) This necessity drove innovations in surveying and projection techniques, leading to maps that more faithfully represented the physical world.

The claim in sentence 3 that the Age of Exploration was a 'significant turning point' for cartography is best supported by which sentence?

Sentence 1 provides a broad definition of cartography and its history.
Sentence 2 describes the non-scientific nature of maps that were created before this era.
Sentence 5 lists some of the specific technical innovations that improved map-making.
Sentence 4 explains that exploration created a new, practical need for accurate maps. (correct answer)

Explanation: When you encounter questions about supporting evidence for claims, you need to identify which statement provides the most direct logical connection to the claim being made. The passage claims that the Age of Exploration was a "significant turning point" for cartography. To support this claim, you need evidence showing what changed and why this change was important. Choice D does exactly this by explaining that exploration "created a growing demand for maps that were navigationally precise." This directly explains why the Age of Exploration marked a turning point—it fundamentally changed what people needed from maps, shifting the entire purpose and direction of cartography. Choice A is incorrect because it only provides a general definition of cartography without connecting to the specific turning point claim. Choice B describes what maps were like before the Age of Exploration, which provides context but doesn't explain why this period was specifically a turning point—it just shows the "before" picture. Choice C discusses the technical innovations that resulted from this turning point, but these are consequences rather than the reason why the period was significant in the first place. The key distinction is between cause and effect. While choices B and C provide relevant context and consequences, only choice D identifies the underlying cause that made the Age of Exploration transformative for cartography. For evidence questions, look for the choice that creates the strongest logical bridge to the claim. Supporting evidence should explain why or how something happened, not just describe what came before or after.

Question 4

(1) The Pacific Ring of Fire is a vast, horseshoe-shaped area in the Pacific Ocean basin. (2) This region is notable for its intense geological activity. (3) The Ring of Fire is where a large number of earthquakes and volcanic eruptions occur. (4) This is because the area marks the meeting point of several tectonic plates that are constantly shifting, colliding, or sliding past one another. (5) Approximately 90% of the world's earthquakes and 75% of its active volcanoes are located along this dynamic geological boundary.

Which sentence provides the best evidence to support the claim in sentence 2 that the Ring of Fire has 'intense geological activity'?

Sentence 1 describes the shape and location of the geological region.
Sentence 5 quantifies the region's activity with specific global percentages. (correct answer)
Sentence 4 explains the underlying tectonic cause for the region's activity.
Sentence 3 specifies the types of geological events that happen in the region.

Explanation: When you encounter a question asking for the "best evidence" to support a claim, you need to identify which piece of information most directly and powerfully proves that claim. The key word here is "intense" - you're looking for evidence that shows the Ring of Fire has exceptionally high levels of geological activity. Sentence 5 provides the strongest evidence because it gives concrete, comparative data: "Approximately 90% of the world's earthquakes and 75% of its active volcanoes are located along this dynamic geological boundary." These specific percentages demonstrate that the Ring of Fire doesn't just have geological activity - it has an overwhelming concentration of the world's most dramatic geological events. This quantitative evidence directly proves the "intense" nature of the region's activity. Choice A is incorrect because describing the Ring of Fire's horseshoe shape and Pacific location doesn't prove anything about activity levels - it's purely geographical information. Choice C explains why the activity occurs (tectonic plate movements) but doesn't demonstrate the intensity level. Choice D identifies what types of events happen (earthquakes and eruptions) but doesn't show how frequent or intense they are compared to other regions. Remember that "best evidence" questions reward you for choosing the most compelling proof. Look for specific data, statistics, or concrete examples rather than general statements or background information. Numbers and comparisons often provide the strongest evidence because they allow readers to grasp the true scale or significance of a claim.

Question 5

(1) The coelacanth, a prehistoric-looking fish, was once known only through the fossil record. (2) Scientists believed it had gone extinct along with the dinosaurs about 66 million years ago. (3) This long-held belief was shattered in 1938 when a living specimen was caught off the coast of South Africa. (4) The discovery was a sensation in the scientific world, akin to finding a living dinosaur. (5) The fish is now considered a 'living fossil,' providing invaluable insights into the evolution of vertebrates.

Which sentence best supports the claim in sentence 4 that the discovery of the coelacanth was a 'sensation'?

Sentence 1 explains that the fish was previously only known from fossil evidence.
Sentence 3 describes the specific event that proved the scientific consensus was incorrect.
Sentence 2 states the long-held scientific consensus that the fish was extinct for millions of years. (correct answer)
Sentence 5 explains the fish's modern scientific importance as a source of evolutionary insight.

Explanation: When you encounter questions asking which sentence "best supports" a claim, you need to identify what evidence would make that claim most convincing. Here, sentence 4 claims the coelacanth discovery was a "sensation" - meaning it was shocking, surprising, and created excitement in the scientific community. The correct answer is C because sentence 2 establishes the crucial context that makes the discovery so sensational: scientists had believed for 66 million years that this fish was extinct. The longer and more firmly held a scientific belief is, the more shocking it becomes when that belief is proven wrong. This 66-million-year timeframe emphasizes just how dramatic and unexpected the discovery was. Let's examine why the other options don't provide the strongest support: A) mentions the fish was only known from fossils, but this alone doesn't convey the shock value - many species are known only from fossils without their discovery being sensational. B) describes the discovery event itself, but doesn't explain why it would be considered shocking rather than just interesting. D) discusses the fish's current scientific value, but this describes consequences of the discovery rather than explaining why the discovery itself was sensational. Remember that "best supports" questions require you to find the piece of evidence that most directly strengthens or validates the specific claim being made. Look for the answer choice that provides the strongest logical foundation for why the claim would be true, not just related information.

Question 6

(1) The discovery of antibiotics revolutionized medicine in the 20th century. (2) Before their introduction, bacterial infections were a leading cause of death, and even a small cut could be fatal. (3) Alexander Fleming's accidental discovery of penicillin in 1928 marked the beginning of a new era. (4) For the first time, physicians had a powerful tool that could effectively kill harmful bacteria without harming the patient. (5) This led to a dramatic increase in life expectancy and made complex surgeries, which carry a high risk of infection, much safer.

Which sentence best supports the claim in sentence 1 that the discovery of antibiotics 'revolutionized medicine'?

Sentence 2 describes the dangerous state of medicine before antibiotics were available.
Sentence 3 gives the specific date and discoverer of the first major antibiotic.
Sentence 4 explains the specific mechanism of action for this new medical tool.
Sentence 5 points to major, society-wide health outcomes like increased life expectancy. (correct answer)

Explanation: When you encounter questions about supporting evidence, you need to identify which detail most directly proves or demonstrates the main claim being made. The claim in sentence 1 is that antibiotics "revolutionized medicine" — meaning they completely transformed medical practice and outcomes. To support this revolutionary impact, you need evidence of major, widespread changes that affected medicine as a whole. Sentence 5 provides exactly this type of evidence by describing two massive transformations: a "dramatic increase in life expectancy" (affecting entire populations) and making "complex surgeries much safer" (transforming surgical practice). These are society-wide changes that demonstrate how antibiotics fundamentally altered medicine's capabilities and outcomes. Let's examine why the other options fall short. Choice A describes the problems that existed before antibiotics, but showing what was wrong doesn't prove that antibiotics revolutionized anything — it just sets up the context. Choice B gives historical facts about Fleming's discovery, but knowing when and who discovered penicillin doesn't demonstrate revolutionary impact. Choice C explains how antibiotics work mechanically, but understanding their mechanism doesn't prove they revolutionized medicine — a tool can work effectively without being revolutionary. Remember that "support" questions ask you to find evidence that proves or demonstrates a claim, not just relates to it. Look for the answer choice that shows concrete results or outcomes that match the scope of the original claim. Revolutionary changes require revolutionary evidence — in this case, society-wide health improvements rather than just background information or technical details.

Question 7

(1) Crows are members of the corvid family, a group of birds known for their remarkable intelligence. (2) Their cognitive abilities are often compared to those of primates. (3) A key reason for their success as a species is their incredible adaptability, particularly their problem-solving skills. (4) For example, New Caledonian crows are famous for creating and using tools, such as shaping twigs into hooks to extract insects from logs. (5) This capacity to innovate and learn allows them to thrive in a wide range of environments, from dense forests to bustling urban centers.

The claim in sentence 3 about crows' 'problem-solving skills' is best supported by which sentence?

Sentence 1 identifies the scientific family to which crows belong.
Sentence 2 makes a general comparison between the intelligence of crows and primates.
Sentence 5 explains the positive outcome of their skills, such as being able to live anywhere.
Sentence 4 provides a specific, concrete example of crows making and using tools to get food. (correct answer)

Explanation: When you encounter questions asking which sentence "supports" a claim, you're being tested on your ability to identify evidence and examples. The key is distinguishing between general statements and specific evidence that proves the claim. The claim in sentence 3 states that crows' "problem-solving skills" are a key reason for their success. To support this claim, you need concrete evidence that demonstrates these problem-solving abilities in action. Sentence 4 provides exactly this type of support by offering a specific, detailed example: New Caledonian crows create tools by "shaping twigs into hooks to extract insects from logs." This directly demonstrates problem-solving skills through observable behavior. The crows identify a problem (getting insects from hard-to-reach places), devise a solution (modify twigs into tools), and execute their plan successfully. This concrete example proves the claim about their problem-solving abilities. Looking at the wrong answers: Choice A simply provides taxonomic classification, which tells us nothing about problem-solving skills. Choice B makes a general comparison to primates but doesn't actually demonstrate any specific problem-solving behavior - it's too vague to serve as evidence. Choice C describes the positive outcomes or benefits of their skills (thriving in various environments) but doesn't show the problem-solving skills themselves in action. Remember this pattern: when a question asks for support of a claim, look for specific examples, evidence, or concrete details rather than general statements or consequences. The best supporting evidence shows the concept in action, not just its results or classifications.

Question 8

(1) Between the 8th and 9th centuries, the Classic Maya civilization experienced a dramatic decline. (2) Major cities were abandoned, and the intricate systems of writing and calendars fell into disuse. (3) While the exact cause of this 'collapse' is still debated, most archaeologists believe it was not a single event but a combination of interrelated factors. (4) Evidence suggests that prolonged drought, exacerbated by widespread deforestation, placed immense strain on the region's resources. (5) This environmental stress likely led to increased warfare, political instability, and the eventual breakdown of the social order.

The claim in sentence 3 that the Maya collapse was caused by a 'combination of interrelated factors' is best supported by which sentence?

Sentence 1 establishes the time period during which the civilization's decline occurred.
Sentence 5 shows how one factor (environmental stress) likely triggered several other social and political problems. (correct answer)
Sentence 4 identifies a severe environmental problem that affected the civilization.
Sentence 2 lists some of the specific outcomes of the collapse, such as abandoned cities.

Explanation: When you encounter questions about supporting evidence, focus on finding which sentence directly demonstrates or proves the claim being made, rather than just providing related information. The claim in sentence 3 states that the Maya collapse resulted from a "combination of interrelated factors" - meaning multiple causes that influenced each other. To support this claim, you need evidence showing how different factors connected and triggered one another. Sentence 5 perfectly demonstrates this interconnected relationship. It shows how environmental stress (the drought and deforestation mentioned in sentence 4) "likely led to" a cascade of other problems: increased warfare, political instability, and social breakdown. This illustrates exactly what "interrelated factors" means - one problem causing multiple others in a chain reaction. Choice A is incorrect because sentence 1 only provides timing information about when the collapse occurred, not evidence about multiple interconnected causes. Choice C is wrong because sentence 4 identifies just one environmental factor, but doesn't show how it connected to other problems. Choice D fails because sentence 2 merely lists outcomes of the collapse (abandoned cities, lost writing systems) rather than explaining the interconnected causes that led to these results. Strategy tip: On evidence questions, distinguish between sentences that provide background information, describe effects, or list single factors versus those that demonstrate relationships between causes. Look for connecting words like "led to," "resulted in," or "caused by" that show how factors influence each other.

Question 9

(1) Cellophane is a thin, transparent sheet made from regenerated cellulose. (2) Its invention in the early 20th century by Swiss chemist Jacques Brandenberger was a direct result of a desire to solve a common problem. (3) Brandenberger was trying to create a waterproof coating for tablecloths to protect them from spills. (4) His initial attempts to apply a liquid viscose coating were unsuccessful as it made the cloth stiff, but he noticed that the coating could be peeled off as a clear film. (5) He immediately recognized the potential of this new transparent material for packaging, and after a decade of development, he perfected the manufacturing process.

Which sentence best supports the claim that the invention of cellophane was accidental?

Sentence 4 describes how he observed an unexpected outcome when his initial experiment failed. (correct answer)
Sentence 3 specifies the original, intended purpose of Brandenberger's experiment.
Sentence 2 states that the invention was the result of trying to solve a different problem.
Sentence 5 explains how the inventor shifted his focus to a new application for the material he created.

Explanation: When you encounter questions about whether an invention was "accidental," you need to identify evidence of an unexpected discovery that occurred while trying to achieve something else entirely. Answer choice A is correct because sentence 4 describes the key moment of accidental discovery. Brandenberger's experiment failed at its intended purpose (the coating made tablecloths stiff), but he noticed an unexpected result: the coating could be peeled off as a clear film. This unplanned observation of a useful byproduct from a failed experiment is the essence of an accidental invention. Let's examine why the other choices don't demonstrate an accident. Choice B describes Brandenberger's original goal (waterproof tablecloth coating), but stating an intended purpose doesn't show that the actual invention was accidental. Choice C mentions he was solving "a different problem," but this doesn't indicate accident—many inventors deliberately tackle various problems. Choice D explains how he later recognized the material's potential for packaging, but changing applications after discovery doesn't prove the discovery itself was accidental. The key distinction is between intention and observation. Sentences 2, 3, and 5 all describe intentional actions and decisions, while only sentence 4 captures that crucial moment when an unexpected outcome revealed something valuable that wasn't being sought. For SHSAT reading questions about cause and effect or invention stories, focus on identifying the specific moment when something unplanned or unexpected occurred. Look for words like "noticed," "observed," or descriptions of failed experiments that led to surprising discoveries.

Question 10

(1) Composting is a natural process that transforms organic waste into a rich, soil-like material. (2) This process offers significant environmental benefits. (3) One key advantage is the reduction of waste sent to landfills. (4) In landfills, organic matter decomposes anaerobically, releasing methane, a potent greenhouse gas that contributes to climate change. (5) By composting this material instead, we not only avoid these emissions but also create a valuable soil amendment that improves soil health and fertility.

The claim in sentence 3 that composting reduces landfill waste is an 'advantage' is best supported by which sentence?

Sentence 4 explains the negative environmental consequence of putting organic waste in landfills. (correct answer)
Sentence 2 makes a general claim that the process has environmental benefits.
Sentence 1 defines composting as a process that transforms organic waste.
Sentence 5 describes the dual benefits of avoiding emissions and creating a useful product.

Explanation: When you encounter questions about supporting evidence, you need to identify which sentence provides the most direct logical support for a specific claim. The question asks which sentence best supports why reducing landfill waste is an "advantage." Sentence 4 provides the strongest support because it explains exactly why sending organic waste to landfills is problematic. It details that organic matter in landfills decomposes anaerobically, releasing methane—a potent greenhouse gas that contributes to climate change. This directly explains why reducing landfill waste is beneficial: it prevents harmful environmental consequences. By showing the negative effects of the alternative (landfills), sentence 4 makes the strongest case for why composting's waste reduction is truly advantageous. Looking at the wrong answers: Choice B is too general—sentence 2 simply states that composting has environmental benefits without explaining why waste reduction specifically matters. Choice C only defines what composting does but doesn't explain why reducing landfill waste is good. Choice D describes additional benefits of composting but doesn't focus on supporting why landfill waste reduction itself is advantageous. Remember that the best supporting evidence directly addresses the specific claim being made. When a question asks you to support why something is an "advantage" or "benefit," look for the sentence that explains the negative consequences of not doing that thing, or the positive effects that result from it. Don't be distracted by sentences that are related to the topic but don't directly support the specific claim in question.

Question 11

(1) The discovery of the double helix structure of DNA in 1953 is one of the most significant scientific achievements of the 20th century. (2) James Watson and Francis Crick are famously credited with this discovery, but their work relied heavily on the contributions of others. (3) Rosalind Franklin, a chemist and X-ray crystallographer, produced a crucial piece of evidence. (4) Her high-resolution X-ray image of a DNA molecule, known as 'Photograph 51,' provided definitive proof of its helical shape. (5) This photograph was essential for Watson and Crick to build their accurate model of the DNA molecule.

The claim in sentence 2 that Watson and Crick's work 'relied heavily on the contributions of others' is best supported by which sentence?

Sentence 1 establishes the overall importance of the discovery of DNA's structure.
Sentence 3 introduces Rosalind Franklin as another scientist involved in DNA research.
Sentence 5 explicitly states that Franklin's work was 'essential' for the creation of their final model. (correct answer)
Sentence 4 describes the specific content and significance of Franklin's X-ray image.

Explanation: When you encounter questions about textual evidence and support, you need to identify which sentence most directly proves or strengthens the given claim. The key is finding the strongest logical connection between the evidence and the assertion. The claim states that Watson and Crick's work "relied heavily on the contributions of others." To support this claim, you need evidence showing that other people's work was not just helpful, but actually necessary for their success. Sentence 5 provides the strongest support because it explicitly states that Franklin's photograph was "essential" for Watson and Crick to build their accurate model. The word "essential" means absolutely necessary—without Franklin's contribution, they couldn't have succeeded. This directly proves they relied heavily on others' work. Looking at the wrong answers: Choice A is incorrect because sentence 1 only establishes the general importance of the DNA discovery, not who contributed to it. Choice B is wrong because sentence 3 merely introduces Franklin as another scientist—it doesn't demonstrate how crucial her work was to Watson and Crick's success. Choice D fails because sentence 4 describes what Franklin's photograph showed, but doesn't establish that this evidence was necessary for Watson and Crick's model. Remember that evidence questions require you to find the most direct and powerful support for a claim. Look for key words like "essential," "crucial," or "necessary" that establish strong causal relationships, rather than sentences that simply provide background information or descriptions.

Question 12

(1) The relationship between humans and cats began thousands of years ago in the Near East. (2) Unlike dogs, which were domesticated for hunting and protection, cats seem to have domesticated themselves. (3) The invention of agriculture led to large stores of grain, which in turn attracted rodents like mice and rats. (4) Wild cats were drawn to these early farming settlements by the abundant prey. (5) Farmers valued the cats for their natural pest-control abilities, creating a mutually beneficial relationship that led to their eventual domestication.

The claim in sentence 2 that 'cats seem to have domesticated themselves' is best supported by which sentence?

Sentence 1 establishes the geographical origin of cat domestication.
Sentence 3 explains the agricultural development that created a new food source for rodents.
Sentence 5 describes the two-sided benefits that cemented the long-term human-cat relationship.
Sentence 4 states that the cats initiated the contact with humans by moving into their settlements. (correct answer)

Explanation: When you encounter a question asking which sentence "best supports" a specific claim, you need to find the sentence that provides the most direct evidence for that particular statement. The claim that "cats seem to have domesticated themselves" suggests that cats, rather than humans, initiated and drove the domestication process. To support this claim, you need evidence showing cats taking the active role in establishing the relationship with humans. Choice D is correct because it directly demonstrates cats taking initiative: "Wild cats were drawn to these early farming settlements by the abundant prey." This sentence shows cats actively seeking out and moving into human settlements on their own, which perfectly supports the idea that they "domesticated themselves" rather than being actively domesticated by humans. Choice A is wrong because simply stating where cat domestication began doesn't explain how it happened or who initiated it. Choice B is incorrect because it only describes agricultural changes that created conditions for rodent populations—it doesn't mention cats at all. Choice C is wrong because while it describes the mutually beneficial relationship, it focuses on the farmers valuing the cats and the eventual outcome, not on cats taking the initial action that started the process. For SHSAT reading questions about textual support, always look for the most direct connection between the evidence and the claim. The supporting sentence should contain specific details that logically prove or demonstrate the statement in question, not just provide related background information.

Question 13

(1) The Rosetta Stone is one of the most famous artifacts in the world, but its importance lies in what it unlocked. (2) Discovered in 1799, the stone is inscribed with a decree issued in 196 BC. (3) Crucially, the same text is presented in three different scripts: Ancient Egyptian hieroglyphs, Demotic script, and Ancient Greek. (4) Because Ancient Greek was well understood by scholars, they were able to use it as a key to decipher the other two unknown scripts. (5) This breakthrough, primarily by Jean-François Champollion, was the first step in understanding the language and culture of ancient Egypt.

Which sentence best supports the claim in sentence 1 that the Rosetta Stone's importance lies in 'what it unlocked'?

Sentence 2 provides historical context about when the stone was found and when its text was written.
Sentence 3 describes the physical characteristic of the stone having three different scripts.
Sentence 4 explains the specific method by which scholars were able to translate the unknown scripts.
Sentence 5 states the broad cultural and historical impact of the stone's translation. (correct answer)

Explanation: When you encounter questions about supporting evidence, you need to identify which sentence most directly reinforces the specific claim being made. The key phrase here is "what it unlocked" — this metaphor suggests the stone opened access to something previously inaccessible. Sentence 5 best supports this claim because it describes the ultimate outcome: the stone unlocked understanding of "the language and culture of ancient Egypt." This directly connects to the metaphor of unlocking — the stone served as a key that opened up an entire civilization's knowledge that had been lost for centuries. The phrase "first step in understanding" shows how the translation breakthrough led to accessing previously unknown information. Let's examine why the other options fall short. Choice A describes when the stone was discovered and dated, which provides background but doesn't explain what was "unlocked." Choice B mentions the three scripts, which is a physical description but doesn't show how this feature led to unlocking knowledge. Choice C explains the translation method scholars used, which describes the process but not the broader significance of what was ultimately revealed. The distinction is crucial: while sentences 3 and 4 describe the stone's features and how it was used, only sentence 5 captures the transformative result — unlocking access to an entire lost civilization's language and culture. For text analysis questions, always look for the choice that most directly addresses the specific language used in the question. Here, focus on what "unlocked" means metaphorically rather than getting distracted by supporting details.

Question 14

(1) Bioluminescence is the production and emission of light by a living organism. (2) This fascinating natural phenomenon is the result of a chemical reaction, during which chemical energy is converted into light energy. (3) For many deep-sea creatures, this ability is not just a beautiful display but a critical tool for survival in the dark ocean depths. (4) For instance, the anglerfish uses a lighted lure to attract unsuspecting prey in the pitch-black environment. (5) Other species use flashes of light to startle predators or to communicate with potential mates.

The claim in sentence 3 that bioluminescence is a 'critical tool for survival' is best supported by which sentence?

Sentence 1 provides the scientific definition of the term bioluminescence.
Sentence 2 explains the chemical process that creates the light.
Sentence 4 gives a specific example of an animal using light to hunt for food. (correct answer)
Sentence 5 mentions that some species use light for communication purposes.

Explanation: When you encounter questions asking which sentence "best supports" a claim, you're being tested on your ability to identify evidence that directly backs up an assertion. Look for concrete examples or specific details that prove the claim is true. The claim in sentence 3 states that bioluminescence is a "critical tool for survival" for deep-sea creatures. To support this claim, you need evidence showing how bioluminescence actually helps these organisms survive. Sentence 4 provides exactly this type of evidence by giving a specific, concrete example: the anglerfish uses its bioluminescent lure to attract prey for food. Since obtaining food is essential for survival, this directly demonstrates how bioluminescence serves as a critical survival tool. Looking at the incorrect options: Answer A simply defines bioluminescence but doesn't explain how it helps with survival. Answer B describes the chemical process behind the light production, which is interesting scientifically but doesn't connect to survival benefits. Answer D mentions communication purposes, which could be related to survival, but it's much more vague than the hunting example and doesn't clearly establish the "critical" nature of this ability for survival. When you see "best supported by" questions on the SHSAT, remember that the strongest support comes from specific examples and concrete evidence, not general definitions or vague statements. Look for the sentence that provides the clearest, most direct illustration of the claim being made.

Question 15

(1) The ancient Library of Alexandria in Egypt was one of the largest and most significant libraries of the ancient world. (2) It was more than just a repository for scrolls; it was a major center of scholarship. (3) The library's mission was to collect a copy of every book ever written. (4) Scholars from across the Mediterranean world were invited to study there, where they had access to an unparalleled collection of knowledge. (5) It was at the Library of Alexandria that fundamental principles of mathematics, astronomy, and medicine were established by figures like Euclid and Eratosthenes.

Which sentence provides the best evidence for the claim in sentence 2 that the library was a 'major center of scholarship'?

Sentence 1 makes a general claim about the library's size and significance.
Sentence 5 lists specific, foundational academic achievements that occurred at the library. (correct answer)
Sentence 4 explains that scholars were actively recruited to come and study at the library.
Sentence 3 describes the ambitious goal of the library's collection policy.

Explanation: When you encounter questions asking for "evidence" to support a claim, you need to find the sentence that most directly demonstrates or proves that claim through concrete examples or facts. The claim in sentence 2 is that the library was a "major center of scholarship." To support this, you need evidence that scholars actually did important scholarly work there. Sentence 5 provides exactly this type of evidence by naming specific scholars (Euclid and Eratosthenes) and explaining that "fundamental principles of mathematics, astronomy, and medicine were established" at the library. This directly proves the library was a center where significant scholarly achievements happened. Let's examine why the other options fall short: Choice A is incorrect because sentence 1 only makes general statements about the library's "significance" without specifically mentioning scholarship or scholarly activities. Choice C is wrong because sentence 4 describes scholars coming to study at the library, but studying somewhere doesn't necessarily make it a center of scholarship—that requires producing new knowledge or breakthroughs. Choice D is incorrect because sentence 3 describes the library's collection goals, which relates to being a repository of knowledge rather than a place where new scholarly work is conducted. Remember that evidence questions require you to distinguish between related information and direct proof. Look for specific examples, concrete achievements, or measurable outcomes rather than general descriptions or related activities. The strongest evidence will show the claim in action, not just describe circumstances around it.

Question 16

(1) Geothermal energy is a powerful and sustainable source of power that originates from the Earth's core. (2) This heat is a byproduct of the planet's formation and the radioactive decay of minerals. (3) To harness this energy, power plants drill deep wells into underground reservoirs to access steam and hot water. (4) This steam is then used to drive turbines connected to electricity generators. (5) Unlike fossil fuels, geothermal plants produce minimal greenhouse gas emissions and have a small physical footprint on the land.

Which sentence best supports the claim in sentence 1 that geothermal energy is 'sustainable'?

Sentence 2 explains the natural origins of the Earth's internal heat.
Sentence 3 describes the process of drilling wells to access geothermal reservoirs.
Sentence 5 contrasts geothermal energy with fossil fuels, highlighting its low emissions. (correct answer)
Sentence 4 explains how steam from the Earth is used to generate electricity.

Explanation: When you encounter questions about supporting evidence, you need to identify which sentence directly backs up the specific claim being made. Here, sentence 1 claims geothermal energy is "sustainable," so you're looking for evidence that proves this particular characteristic. Sentence 5 provides the strongest support for sustainability by contrasting geothermal energy with fossil fuels, emphasizing that geothermal plants "produce minimal greenhouse gas emissions and have a small physical footprint." This directly addresses sustainability by showing geothermal energy's environmental advantages—low emissions and minimal land use are key indicators of a sustainable energy source. Let's examine why the other options fall short. Choice A describes the natural origins of Earth's heat, but explaining where geothermal energy comes from doesn't prove it's sustainable. Choice B details the drilling process to access geothermal reservoirs, which is about extraction methods rather than sustainability. Choice D explains how steam generates electricity, focusing on the conversion process rather than environmental impact. The key distinction is that sustainability refers to an energy source's ability to meet current needs without compromising future generations' ability to meet their needs. This involves environmental impact, resource depletion, and long-term viability. Only sentence 5 addresses these sustainability concerns by highlighting geothermal energy's minimal environmental footprint. Remember: when questions ask for supporting evidence, match the evidence directly to the specific claim. Don't be distracted by sentences that provide background information or describe processes—focus on which sentence actually proves the particular point being made.

Question 17

(1) The QWERTY keyboard layout is the most common layout used today, but its design was not based on efficiency. (2) Early mechanical typewriters had a problem: if a user typed too quickly, the metal arms, or 'typebars,' would jam together. (3) To solve this, inventor Christopher Sholes designed a layout that deliberately separated frequently used letter pairs, such as 'th' or 'st.' (4) This arrangement slowed typists down just enough to prevent the keys from clashing. (5) Though modern computers do not have this mechanical limitation, the QWERTY layout persists due to its widespread adoption.

Which sentence best supports the claim in sentence 1 that the QWERTY layout was 'not based on efficiency'?

Sentence 2 describes a mechanical problem that existed with early models of typewriters.
Sentence 4 states that the design's intended purpose was to make typing slower. (correct answer)
Sentence 3 explains the inventor's strategy for arranging the letters on the keyboard.
Sentence 5 discusses why the layout continues to be used despite technological advances.

Explanation: When you encounter a question asking which sentence "best supports" a specific claim, you're being tested on your ability to identify the most direct evidence for that claim. Here, you need to find which sentence most clearly demonstrates that QWERTY was "not based on efficiency." The correct answer is B because sentence 4 directly contradicts the idea of efficiency. It explicitly states that the QWERTY design was intended "to slow typists down" - the exact opposite of what an efficiency-focused design would do. This sentence provides the clearest evidence that efficiency was not the goal; in fact, deliberate inefficiency was the goal. Let's examine why the other choices don't work as well: A) Sentence 2 only describes the problem that needed solving, but doesn't explain how the solution was inefficient. C) Sentence 3 explains the strategy of separating letter pairs, but this could potentially be seen as efficient problem-solving rather than proof of inefficiency. D) Sentence 5 discusses why QWERTY persists today, which is about modern usage rather than the original design intent. When analyzing supporting evidence questions on the SHSAT, look for the sentence that most directly proves or demonstrates the claim being made. Don't get distracted by sentences that provide related information or context - focus on which one offers the strongest, most explicit support for the specific assertion in question.

Question 18

(1) The Viking longship was the vessel that enabled Norse expansion across Europe and the North Atlantic. (2) Its design was a technological marvel for its time, perfectly suited to the Vikings' needs for trade, exploration, and warfare. (3) The longship's most critical feature was its shallow draft, which meant the boat did not sit deep in the water. (4) This allowed the Vikings to navigate not only open seas but also shallow rivers, enabling them to travel far inland to raid or trade in areas inaccessible to other ships. (5) This versatility gave them a significant strategic advantage.

Which sentence best supports the claim in sentence 5 that the longship's design gave the Vikings a 'significant strategic advantage'?

Sentence 2 makes the general claim that the ship's design was a 'technological marvel.'
Sentence 4 explains that the design allowed them to access inland areas that other ships could not reach. (correct answer)
Sentence 3 identifies the specific design feature of a shallow draft.
Sentence 5 repeats the claim about the strategic advantage of the ship's versatility.

Explanation: When you encounter questions asking which sentence "supports" a claim, you're being tested on your ability to identify evidence that directly backs up a statement with specific details or examples. The claim in sentence 5 states that the longship's design gave Vikings a "significant strategic advantage." To support this claim, you need evidence that shows how this advantage worked in practice. Sentence 4 provides exactly that evidence by explaining the practical benefit: the shallow draft design "allowed the Vikings to navigate not only open seas but also shallow rivers, enabling them to travel far inland to raid or trade in areas inaccessible to other ships." This sentence demonstrates the strategic advantage by showing how the design feature gave Vikings unique access that their enemies and competitors lacked. Choice A mentions the ship was a "technological marvel," but this is too general and doesn't explain what strategic advantage this gave them. Choice C identifies the shallow draft feature, but simply naming a design element doesn't show how it created an advantage. Choice D doesn't support the claim at all—it is the claim, just restated using "versatility" instead of "design." Only choice B explains the cause-and-effect relationship: specific design → unique capability → strategic advantage over others. Remember that "support" questions require concrete evidence or examples, not general statements or restatements of the claim. Look for the answer that shows how or why the claim is true through specific details.

Question 19

(1) Mycelium is the intricate root-like network of a fungus. (2) While often hidden underground, this complex web plays a vital role in forest ecosystems by breaking down organic matter. (3) Recently, however, scientists and designers have begun to explore its potential as a sustainable material. (4) Mycelium can be grown into specific shapes and then dried to create a substance that is lightweight, strong, and completely biodegradable. (5) It is now being used to make everything from packing materials that replace Styrofoam to building insulation and even textiles.

The claim in sentence 3 that mycelium has 'potential as a sustainable material' is best supported by which sentence?

Sentence 1 provides a basic definition of what mycelium is in the natural world.
Sentence 2 describes the natural ecological function of mycelium in forests.
Sentence 4 lists the specific physical properties that make mycelium a useful and eco-friendly substance. (correct answer)
Sentence 5 provides a series of diverse examples of products currently being made from the material.

Explanation: When you encounter a question asking which sentence "best supports" a claim, you're being tested on your ability to identify the most direct and relevant evidence for that specific assertion. The claim in sentence 3 states that mycelium has "potential as a sustainable material." To support this claim, you need evidence that demonstrates why mycelium would actually work well as an eco-friendly material option. Sentence 4 provides exactly this evidence by listing mycelium's key physical properties: it's "lightweight, strong, and completely biodegradable." These three qualities directly explain why mycelium has potential as a sustainable material—it performs well functionally while being environmentally friendly. Choice A is incorrect because simply defining what mycelium is doesn't explain why it would make a good sustainable material. Choice B describes mycelium's natural role in breaking down organic matter, which relates to ecosystems but doesn't directly support its potential as a manufactured material. Choice D lists current applications of mycelium, but this shows that the potential has already been realized rather than supporting why the potential exists in the first place. The key distinction is between evidence that explains the reasoning behind a claim versus evidence that simply provides related information. When looking for support for a claim about "potential," focus on sentences that explain the underlying qualities or characteristics that create that potential, rather than background information or examples of the potential being fulfilled.

Question 20

(1) Mangrove forests are unique coastal ecosystems found in tropical and subtropical regions. (2) With their dense tangle of prop roots, these forests act as a natural barrier. (3) This structure is incredibly effective at protecting coastlines from erosion and storm surge. (4) The roots dissipate wave energy, reducing the impact of storms on coastal communities and stabilizing the shoreline. (5) They also provide critical nursery habitats for a wide variety of marine life.

The claim that mangroves protect coastlines (sentence 3) is best supported by the details in which sentence?

Sentence 1 identifies the geographical locations where mangrove forests are typically found.
Sentence 4 explains the specific mechanism by which the roots reduce wave energy and stabilize land. (correct answer)
Sentence 2 introduces the idea of the forests' roots acting as a type of natural barrier.
Sentence 5 describes an additional ecological benefit related to marine animal habitats.

Explanation: When you encounter questions asking which sentence "supports" a claim, you're being tested on your ability to identify evidence and distinguish between different types of textual support. The claim in sentence 3 states that mangrove structure is "incredibly effective at protecting coastlines from erosion and storm surge." To support this claim, you need evidence that explains how or why this protection works—not just related information about mangroves. Choice B is correct because sentence 4 provides the specific mechanism behind the protection: "The roots dissipate wave energy, reducing the impact of storms on coastal communities and stabilizing the shoreline." This directly explains why mangroves are effective protectors, offering concrete evidence for the effectiveness claim. Now let's examine why the other choices fall short. Choice A simply tells us where mangroves are located geographically, but location doesn't support the claim about protective effectiveness. Choice C introduces the concept of roots as barriers, but this is more of a setup than support—it doesn't explain why or how well they work as barriers. Choice D describes a completely different benefit (marine habitats) that doesn't relate to coastal protection at all. Remember: when questions ask what "supports" a claim, look for the choice that provides evidence, explanation, or proof of that specific claim. Avoid choices that merely provide background information, introduce related concepts, or discuss entirely different topics. The strongest support explains the "how" or "why" behind the claim.
