All questions
Question 1
(1) The invention of the printing press by Johannes Gutenberg in the mid-15th century was a pivotal moment in human history. (2) It allowed for the mass production of books, making knowledge far more accessible to the general public than ever before. (3) Many of the earliest books printed by Gutenberg were religious texts, including his famous 42-line Bible. (4) This revolution in communication fueled the Renaissance and the Reformation by enabling new ideas to spread with unprecedented speed across Europe.
The author wants to remove a sentence that is least relevant to the paragraph's main idea about the impact of the printing press. Which sentence should be removed?
- Sentence 1
- Sentence 2
- Sentence 4
- Sentence 3 (correct answer)
Explanation: When you encounter questions about paragraph coherence, focus on identifying the main idea and evaluating how well each sentence supports that central point.
This paragraph's main idea centers on the impact of Gutenberg's printing press—specifically how it transformed society by making knowledge more accessible and enabling the spread of ideas. Let's examine each sentence through this lens.
Sentence 3 provides specific details about what Gutenberg printed (religious texts and his 42-line Bible), but it doesn't explain how these publications created societal impact. While this information is historically accurate, it's more of a factual detail than evidence of the printing press's transformative effects. This makes it the least relevant to the paragraph's focus on impact.
Choice A is incorrect because Sentence 1 establishes the historical significance of Gutenberg's invention, setting up the impact discussion. Choice B is wrong because Sentence 2 directly explains a major impact—making knowledge accessible to the general public. Choice C is incorrect because Sentence 4 demonstrates the printing press's profound societal impacts by connecting it to major historical movements like the Renaissance and Reformation.
The key difference is that Sentences 1, 2, and 4 all address consequences and effects of the invention, while Sentence 3 merely describes the content of early printed materials without connecting that content to broader impacts.
Strategy tip: When evaluating paragraph unity, ask yourself: "Does this sentence answer the same question as the others?" Here, most sentences answer "What impact did this have?" while Sentence 3 answers "What did he print?"
Question 2
(1) Photosynthesis is the critical process through which green plants convert light energy into chemical energy. (2) During this process, plants use sunlight, water, and carbon dioxide to create glucose, which serves as their food. (3) Cellular respiration, on the other hand, is the process by which organisms break down glucose to release energy for their cells. (4) As a vital byproduct of photosynthesis, oxygen is released into the atmosphere, which most living organisms depend upon for survival.
Which sentence disrupts the paragraph's specific focus on the process of photosynthesis?
- Sentence 1
- Sentence 2
- Sentence 3 (correct answer)
- Sentence 4
Explanation: When you encounter questions about paragraph unity and focus, you need to identify which sentence strays from the main topic or organizational pattern. This paragraph is specifically focused on explaining the process of photosynthesis.
Looking at each sentence's role in the paragraph, you can see that most maintain this focus. Sentence 1 introduces photosynthesis as the main topic, defining it as the process that converts light energy to chemical energy. Sentence 2 continues explaining photosynthesis by detailing the specific inputs (sunlight, water, carbon dioxide) and output (glucose). Sentence 4 extends the photosynthesis discussion by mentioning oxygen as another product of this process.
However, Sentence 3 shifts away from photosynthesis entirely. It introduces cellular respiration, which is a completely different biological process that breaks down glucose rather than creating it. While cellular respiration is related to photosynthesis in the broader context of plant biology, it disrupts the paragraph's specific focus on explaining how photosynthesis works.
Choice A is incorrect because Sentence 1 establishes the main topic. Choice B is wrong because Sentence 2 directly explains the photosynthesis process with specific details. Choice D is incorrect because Sentence 4 discusses oxygen production, which is part of photosynthesis.
For paragraph unity questions on the SHSAT, always identify the paragraph's specific focus first, then look for the sentence that introduces a different topic or concept, even if it's related to the main subject. The key is staying within the established scope.
Question 3
(1) The Roman Colosseum, an iconic symbol of imperial power, was commissioned around A.D. 70-72 by Emperor Vespasian. (2) This massive stone amphitheater was designed to host spectacular public events, including gladiatorial contests, animal hunts, and mock sea battles. (3) Roman architecture is also known for its extensive use of arches, vaults, and domes. (4) Capable of holding an estimated 50,000 to 80,000 spectators, the Colosseum served as the primary entertainment venue in ancient Rome for centuries.
Which sentence is least relevant to the paragraph's description of the Roman Colosseum?
- Sentence 1
- Sentence 2
- Sentence 3 (correct answer)
- Sentence 4
Explanation: When you encounter questions about paragraph relevance, you need to identify the main focus and determine which sentence strays from that central topic. This paragraph is specifically about the Roman Colosseum itself—its construction, purpose, capacity, and historical significance.
Sentence 3 is the least relevant because it shifts away from the Colosseum to discuss Roman architecture in general. While the information about arches, vaults, and domes is factually accurate and relates to Roman building techniques, it doesn't directly contribute to the paragraph's specific focus on the Colosseum's history, design purpose, or impact. The sentence feels like a tangent that would be better suited for a broader discussion of Roman architectural achievements.
Let's examine why the other options are wrong: Choice A (Sentence 1) is highly relevant because it establishes the Colosseum's historical context, identifying who commissioned it and when. Choice B (Sentence 2) directly supports the main topic by explaining the Colosseum's specific design purpose and the events it hosted. Choice D (Sentence 4) is essential because it provides concrete details about the structure's capacity and its role as Rome's primary entertainment venue.
When tackling relevance questions on the SHSAT, always identify the paragraph's specific focus first, then look for the sentence that introduces a related but distinct topic. The least relevant sentence often contains accurate information that simply belongs in a different discussion—watch for these subtle shifts in focus rather than factual errors.
Question 4
(1) Marie Curie's groundbreaking research on radioactivity had a profound and lasting impact on science and medicine. (2) Along with her husband, Pierre, she discovered two new elements, polonium and radium, which fundamentally altered our understanding of atomic structure. (3) Marie Curie was born in Warsaw, Poland, and later moved to France for her university education. (4) Her work laid the foundation for modern nuclear physics and led to the development of X-rays and radiation therapy for treating cancer.
Which sentence should be removed to maintain the paragraph's focus on the scientific impact of Marie Curie's work?
- Sentence 3 (correct answer)
- Sentence 2
- Sentence 1
- Sentence 4
Explanation: When you encounter questions about paragraph coherence, you need to identify the main focus and determine which sentences support that central idea versus which ones drift off-topic.
This paragraph's focus is clearly established in the opening sentence: the scientific impact of Marie Curie's research. Every sentence should connect to how her work influenced science and medicine.
Sentence 3 disrupts this focus because it provides biographical information about where Curie was born and educated. While this background might be interesting, it doesn't explain how her work impacted science. It's purely personal history that doesn't advance the paragraph's central argument about her scientific contributions.
Looking at why the other choices are wrong: Sentence 1 (choice C) establishes the main topic about scientific impact, so removing it would eliminate the paragraph's focus entirely. Sentence 2 (choice B) directly supports the main idea by explaining her specific discoveries and their impact on atomic theory. Sentence 4 (choice D) continues the scientific impact theme by describing practical applications in medicine and physics that resulted from her work.
Notice that sentences 1, 2, and 4 all contain words related to scientific impact: "profound impact," "fundamentally altered our understanding," and "laid the foundation for modern nuclear physics." Sentence 3 lacks any such language.
Strategy tip: When checking paragraph unity, scan each sentence for keywords that connect to the main topic. Sentences that lack these connecting words or introduce unrelated information are usually the ones that should be removed.
Question 5
(1) The Great Barrier Reef, located off the coast of Australia, is the world's largest coral reef system. (2) Composed of over 2,900 individual reefs and 900 islands, it is one of the most biodiverse ecosystems on the planet. (3) It is home to a stunning array of marine life, including countless species of fish, corals, mollusks, and sea turtles. (4) Many coastal areas around the world rely on fishing as a primary industry for their economy.
Which sentence should be removed from the paragraph to keep the focus on the Great Barrier Reef?
- Sentence 1
- Sentence 2
- Sentence 3
- Sentence 4 (correct answer)
Explanation: When you encounter questions about paragraph unity, you need to identify which sentence doesn't support the main topic. Every sentence in a well-written paragraph should relate directly to the central focus.
This paragraph focuses specifically on the Great Barrier Reef and its characteristics. Sentences 1, 2, and 3 all work together to build a complete picture of this particular reef system. Sentence 1 introduces the reef and establishes its significance as the world's largest coral reef system. Sentence 2 provides specific details about its size and biodiversity. Sentence 3 continues describing the reef by listing the types of marine life it supports.
Sentence 4, however, shifts away from the Great Barrier Reef entirely. While it mentions fishing and coastal economies, it makes a general statement about "many coastal areas around the world" rather than discussing the Great Barrier Reef specifically. This breaks the paragraph's focus and introduces an unrelated topic.
Looking at the wrong answers: Choice A eliminates the topic sentence that introduces the reef, which would leave readers confused about what's being discussed. Choice B removes crucial details about the reef's composition and biodiversity. Choice C takes away the specific examples of marine life that help readers understand what makes the reef special.
Remember that strong paragraphs maintain a single, clear focus throughout. When identifying sentences that don't belong, look for ones that introduce new topics or shift away from the main subject, even if they're loosely related to the general theme.
Question 6
(1) The Silk Road was not a single route but a vast network of trade routes connecting the East and West for more than 1,500 years. (2) It was instrumental in the exchange of goods like silk, spices, and precious metals between China, India, Persia, and the Roman Empire. (3) Beyond commerce, it also facilitated the transmission of ideas, religions, and technologies, profoundly shaping the cultures it connected. (4) The Great Wall of China was built over centuries primarily as a defensive fortification against invasions.
Which sentence should be removed because it deviates from the paragraph's focus on the Silk Road?
- Sentence 1
- Sentence 2
- Sentence 3
- Sentence 4 (correct answer)
Explanation: This question tests your ability to identify sentences that break paragraph unity - when all sentences should work together to develop one main topic.
When analyzing paragraph coherence, look at each sentence's relationship to the main subject. Sentences 1, 2, and 3 all directly discuss the Silk Road: sentence 1 defines what it was (a network of trade routes), sentence 2 explains its commercial purpose (exchanging goods between empires), and sentence 3 expands on its broader cultural impact (spreading ideas, religions, and technologies). These three sentences work together to paint a complete picture of the Silk Road's significance.
Sentence 4, however, shifts abruptly to discussing the Great Wall of China as a defensive fortification against invasions. While the Great Wall is also a famous Chinese landmark, it has no connection to the Silk Road's function as a trade network. This sentence disrupts the paragraph's focus and should be removed.
Looking at the wrong answers: Choice A is incorrect because sentence 1 introduces the main topic and provides essential context. Choice B is wrong because sentence 2 explains the Silk Road's primary commercial function, which directly supports the main topic. Choice C is incorrect because sentence 3 builds on sentence 2 by showing the Silk Road's broader cultural significance beyond just trade.
When you encounter paragraph unity questions, mentally summarize the main topic after reading, then check if each sentence contributes to developing that topic. Any sentence that introduces unrelated information, no matter how interesting, weakens the paragraph's focus.
Question 7
(1) Jazz music, which originated in African American communities of New Orleans in the late 19th century, is a uniquely American art form. (2) It is characterized by its use of improvisation, syncopation, and a swinging rhythm. (3) New Orleans is also famous for its annual Mardi Gras celebration, which attracts tourists from all over the world. (4) From its early days of ragtime and blues, jazz has evolved into a wide variety of styles, including swing, bebop, and fusion.
Which sentence does not contribute to the paragraph's description of jazz music?
- Sentence 1
- Sentence 2
- Sentence 3 (correct answer)
- Sentence 4
Explanation: When you encounter questions about paragraph unity, you need to identify which sentences support the main topic and which ones stray from it. This paragraph is clearly focused on describing jazz music as an art form.
Let's examine what each sentence contributes to this description. Sentence 1 establishes jazz's origins in African American communities of New Orleans and identifies it as a uniquely American art form. This directly supports the main topic by providing historical context and cultural significance. Sentence 2 describes jazz's defining musical characteristics: improvisation, syncopation, and swinging rhythm. This is essential information about what makes jazz distinctive as a musical style. Sentence 4 traces jazz's evolution from ragtime and blues through various styles like swing, bebop, and fusion, showing how the genre has developed over time.
However, sentence 3 discusses New Orleans' Mardi Gras celebration and its tourist appeal. While this sentence mentions New Orleans (which was referenced in sentence 1), it shifts the focus away from jazz music entirely to talk about a completely different cultural phenomenon. The fact that both jazz and Mardi Gras are associated with New Orleans doesn't make this sentence relevant to a paragraph specifically about describing jazz music.
Choice A is wrong because sentence 1 establishes jazz's origins and cultural identity. Choice B is incorrect since sentence 2 defines jazz's core musical elements. Choice D is wrong because sentence 4 traces jazz's stylistic evolution.
For paragraph unity questions, always ask: "Does this sentence directly support the main topic, or does it introduce unrelated information?" Even seemingly connected details can be distracting if they don't serve the paragraph's specific purpose.
Question 8
(1) The study of archaeology allows us to understand past human societies through the recovery and analysis of material culture. (2) Archaeologists excavate sites to find artifacts, such as tools, pottery, and jewelry, which provide clues about daily life in the past. (3) Geologists, in a different field, study the solid Earth, the rocks of which it is composed, and the processes by which they change. (4) By examining the remains of buildings and other structures, they can also reconstruct the physical environments and social organization of ancient civilizations.
Which sentence should be removed to maintain the paragraph's focus on the field of archaeology?
- Sentence 1
- Sentence 2
- Sentence 3 (correct answer)
- Sentence 4
Explanation: When you encounter questions about paragraph unity and focus, you need to identify which sentence disrupts the main topic and doesn't belong with the others.
This paragraph focuses specifically on archaeology as a field of study. Let's examine how each sentence relates to this central theme.
Sentence 3 is the correct answer to remove because it shifts away from archaeology entirely to discuss geology. While it mentions that geologists work "in a different field," this acknowledgment actually highlights why it doesn't belong—it's introducing completely unrelated information about studying rocks and Earth processes that has no connection to archaeological methods or discoveries.
Looking at why the other options are wrong: Sentence 1 (A) establishes the paragraph's main focus by defining archaeology and its purpose, making it essential to keep. Sentence 2 (B) directly supports the topic by explaining specific archaeological methods and the types of artifacts archaeologists find. Sentence 4 (D) continues discussing archaeological work by describing how archaeologists analyze structural remains to understand past civilizations, which clearly relates to the field's goals mentioned in sentence 1.
The paragraph flows logically from defining archaeology, to explaining excavation methods and artifacts, to describing how archaeologists interpret structural evidence—except for the geology tangent in sentence 3.
Strategy tip: When checking paragraph unity, ask yourself if each sentence directly relates to the main topic. Watch for sentences that introduce new, unrelated subjects, even if they seem academically connected. Stay focused on the specific field or concept being discussed.
Question 9
(1) Harriet Tubman was a leading abolitionist and the most famous "conductor" on the Underground Railroad. (2) Born into slavery, she escaped and subsequently made some thirteen missions to rescue approximately seventy enslaved people, including family and friends. (3) The American Civil War was fought from 1861 to 1865 between the United States and the Confederacy. (4) Using the network of antislavery activists and safe houses known as the Underground Railroad, she guided the escapees to freedom in the North.
Which sentence is least relevant to the paragraph's description of Harriet Tubman's role in the Underground Railroad?
- Sentence 1
- Sentence 2
- Sentence 4
- Sentence 3 (correct answer)
Explanation: When you encounter a question asking which sentence is "least relevant," you're being tested on paragraph unity and coherence. You need to identify which sentence doesn't directly support the main topic or theme.
This paragraph focuses specifically on Harriet Tubman's role in the Underground Railroad. Let's examine how each sentence contributes to this central theme.
Sentence 3 provides general information about the Civil War's dates and participants, but it doesn't connect Tubman to the Underground Railroad or explain her role in it. While the Civil War is historically related to the abolition of slavery, this sentence stands alone without establishing any clear connection to Tubman's Underground Railroad activities. It disrupts the paragraph's flow and doesn't advance the discussion of her specific contributions.
Looking at the other options: Sentence 1 (A) directly introduces Tubman as the most famous Underground Railroad "conductor," establishing the paragraph's main focus. Sentence 2 (B) is highly relevant because it explains her personal experience with slavery and quantifies her rescue missions, showing the scope of her Underground Railroad work. Sentence 4 (C) directly describes how she used the Underground Railroad network to guide people to freedom, which is central to understanding her role.
The correct answer is D because sentence 3 provides background information that doesn't directly relate to Tubman's Underground Railroad activities.
Strategy tip: When identifying irrelevant sentences, ask yourself: "Does this sentence directly support or explain the main topic?" If it provides only loosely related background information without clear connection to the central theme, it's likely the least relevant.
Question 10
(1) The human brain is an incredibly complex organ responsible for controlling all of the body's functions. (2) It is divided into several distinct regions, each with specialized roles, such as the cerebrum for thought and the cerebellum for balance and coordination. (3) The average adult human heart beats approximately 72 times per minute. (4) This command center of the nervous system processes information from our senses, enabling us to learn, remember, and interact with the world.
Which sentence should be removed because it does not relate to the topic of the human brain?
- Sentence 3 (correct answer)
- Sentence 2
- Sentence 1
- Sentence 4
Explanation: This question tests your ability to identify irrelevant information that disrupts the unity and focus of a paragraph. When you encounter questions about removing sentences, look for the one that strays from the main topic or introduces unrelated information.
Let's examine what each sentence contributes to the passage's focus on the human brain. Sentence 1 introduces the brain as a complex organ controlling body functions, establishing the main topic. Sentence 2 builds on this by describing the brain's regions and their specialized roles like the cerebrum and cerebellum. Sentence 4 continues discussing the brain as the nervous system's command center, explaining how it processes sensory information for learning and memory.
However, sentence 3 suddenly shifts to discussing the human heart and its beating rate. This information about cardiovascular function has nothing to do with brain structure or function, making it completely off-topic and disruptive to the paragraph's coherence.
Looking at why the other choices are wrong: Choice B (sentence 2) is incorrect because it directly supports the main topic by explaining brain regions. Choice C (sentence 1) is wrong since it serves as the topic sentence introducing the brain. Choice D (sentence 4) is incorrect because it reinforces the brain's role in processing information and controlling bodily functions.
Strategy tip: When identifying sentences to remove, ask yourself: "Does this sentence directly relate to the main topic established in the first sentence?" If it introduces completely different subject matter, it likely needs to go.
Question 11
(1) The Impressionist art movement, which emerged in the late 19th century, sought to capture the immediate sensory effect of a scene. (2) Artists like Claude Monet focused on the changing qualities of light and color, often painting the same subject multiple times in different conditions. (3) They employed visible brushstrokes and an open composition to convey a sense of spontaneity and movement. (4) The Renaissance period, which preceded Impressionism by several centuries, was characterized by a focus on realism and humanism.
Which sentence is least relevant to the paragraph's description of the Impressionist movement?
- Sentence 4 (correct answer)
- Sentence 2
- Sentence 3
- Sentence 1
Explanation: When you encounter questions about paragraph relevance, you need to identify the main topic and determine which sentences support it versus which ones stray from that focus.
This paragraph is specifically about the Impressionist art movement. Let's examine how each sentence relates to this central topic. Sentence 1 introduces Impressionism and its core philosophy of capturing immediate sensory effects. Sentence 2 provides a concrete example with Claude Monet, showing how Impressionist artists worked with light and color. Sentence 3 describes specific Impressionist techniques like visible brushstrokes and open composition.
However, sentence 4 abruptly shifts to discussing the Renaissance period, which occurred "several centuries" before Impressionism. While it mentions that Renaissance art focused on "realism and humanism," this information doesn't help explain what Impressionism was about or how it worked. The sentence feels like it was pulled from a different paragraph entirely.
Looking at the wrong answers: B (sentence 2) is highly relevant because it gives a specific example of an Impressionist artist and his methods. C (sentence 3) directly supports the main topic by explaining key Impressionist techniques. D (sentence 1) serves as the topic sentence that establishes what the entire paragraph will discuss.
The correct answer is A because sentence 4 disrupts the paragraph's focus on Impressionism by introducing an unrelated historical period.
Strategy tip: For relevance questions, first identify the paragraph's main topic, then ask yourself: "Does this sentence help explain, support, or develop that topic?" Any sentence that feels like it belongs in a different discussion is likely your answer.
Question 12
(1) How volcanoes are formed is a direct result of tectonic plate movement. (2) When plates collide or pull apart, magma from the Earth's mantle can rise to the surface. (3) Earthquakes are also commonly caused by the movement of tectonic plates along fault lines. (4) Over time, repeated eruptions of lava and ash build up, creating the cone-shaped structure we recognize as a volcano.
Which sentence disrupts the paragraph's explanation of volcano formation?
- Sentence 1
- Sentence 2
- Sentence 3 (correct answer)
- Sentence 4
Explanation: When you encounter questions about paragraph unity, you're being tested on whether you can identify sentences that don't support the main topic or logical flow of ideas.
This paragraph focuses specifically on how volcanoes are formed. Let's trace the logical sequence: Sentence 1 introduces the main idea that volcano formation results from tectonic plate movement. Sentence 2 explains the mechanism—when plates move, magma rises to the surface. Sentence 4 describes how repeated eruptions build up the volcanic structure over time. These three sentences work together to create a clear, focused explanation of volcano formation.
Sentence 3, however, shifts the discussion to earthquakes and fault lines. While earthquakes are also caused by tectonic plate movement, this information doesn't contribute to explaining how volcanoes form. It's a related but separate geological phenomenon that disrupts the paragraph's focused explanation.
Looking at the wrong answers: Choice A (Sentence 1) is incorrect because it establishes the paragraph's main topic. Choice B (Sentence 2) is wrong because it directly explains the mechanism of volcano formation introduced in Sentence 1. Choice D (Sentence 4) is incorrect because it logically continues the explanation by describing how volcanic structures develop over time.
When tackling paragraph unity questions on the SHSAT, always identify the main topic first, then check whether each sentence directly supports or develops that specific topic. Any sentence that introduces a different concept—even a related one—likely disrupts the paragraph's focus.
Question 13
(1) Jane Austen's novels are celebrated for their sharp wit, social commentary, and insightful character development. (2) Works like Pride and Prejudice and Sense and Sensibility explore the concerns and relationships of the English gentry at the turn of the 19th century. (3) She masterfully used irony and satire to critique the social conventions and expectations placed upon women during her time. (4) The Victorian Era, which followed Austen's Regency period, saw a different set of literary themes and styles emerge.
Which sentence is least relevant to the paragraph's focus on Jane Austen's literary work?
- Sentence 1
- Sentence 2
- Sentence 3
- Sentence 4 (correct answer)
Explanation: When you encounter questions about paragraph relevance, you need to identify the main focus and determine which sentence doesn't support that central theme.
This paragraph focuses specifically on Jane Austen's literary work and her contributions to literature. Let's examine how each sentence relates to this focus.
Sentence 4 is the correct answer because it shifts away from discussing Austen's work to mention the Victorian Era and its different literary themes. While this information might be historically interesting, it doesn't contribute to understanding Austen's novels, her writing techniques, or her literary significance. The paragraph is about Austen herself, not the broader literary periods.
Choice A is wrong because sentence 1 directly introduces the main topic by highlighting what makes Austen's novels celebrated—their wit, social commentary, and character development. This sets up the entire paragraph's focus.
Choice B is incorrect because sentence 2 provides specific examples of Austen's works and explains what themes she explored, directly supporting the paragraph's focus on her literary contributions.
Choice C is wrong because sentence 3 elaborates on Austen's specific literary techniques (irony and satire) and explains how she used them to critique social conventions, which directly relates to the social commentary mentioned in sentence 1.
For relevance questions, identify the paragraph's main purpose first, then ask yourself: "Does this sentence help explain, support, or develop the main idea?" Any sentence that introduces unrelated information or shifts focus to a different topic is likely your answer.
Question 14
(1) The Articles of Confederation represented the first constitutional agreement made between the 13 original American states. (2) Ratified in 1781, this document established a weak central government, granting most powers to the individual states. (3) This structure soon proved ineffective, as the federal government lacked the authority to tax or regulate commerce, leading to economic turmoil. (4) The Declaration of Independence, written in 1776, announced the colonies' separation from Great Britain.
Which sentence should be removed to maintain the paragraph's focus on the Articles of Confederation?
- Sentence 1
- Sentence 2
- Sentence 4 (correct answer)
- Sentence 3
Explanation: This question tests your ability to identify sentences that disrupt paragraph unity and coherence. When evaluating whether a sentence belongs in a paragraph, you need to check if it directly supports the main topic and flows logically with the surrounding content.
The paragraph's clear focus is the Articles of Confederation - what it was, when it was ratified, and why it failed. Sentences 1, 2, and 3 all directly relate to this topic. Sentence 1 introduces the Articles as the first constitutional agreement. Sentence 2 explains when it was ratified and its key characteristic of creating weak central government. Sentence 3 discusses the problems this weakness caused, explaining why the Articles proved ineffective.
Sentence 4, however, shifts abruptly to the Declaration of Independence from 1776. While both documents are historically important, the Declaration of Independence is a completely different topic - it was about declaring independence from Britain, not about governing the new nation. This sentence breaks the paragraph's focus and creates confusion for readers expecting to learn about the Articles of Confederation.
Looking at the wrong answers: (A) Sentence 1 correctly introduces the main topic, so removing it would eliminate the paragraph's foundation. (B) Sentence 2 provides essential details about ratification and the document's structure. (D) Sentence 3 explains the consequences and problems, which directly supports the paragraph's purpose.
Strategy tip: When identifying irrelevant sentences, ask yourself: "Does this sentence advance the main topic, or does it introduce new information that belongs elsewhere?" Stay focused on the paragraph's central theme.
Question 15
(1) Hibernation is a state of inactivity and metabolic depression in endotherms, often used to survive cold winter months. (2) During hibernation, an animal's heart rate, breathing, and body temperature drop significantly to conserve energy. (3) Many bird species migrate to warmer climates during the winter to find food. (4) Animals such as bears, groundhogs, and some bats enter this dormant state, living off of fat reserves they stored during the autumn.
Which sentence is least relevant to the paragraph's explanation of hibernation?
- Sentence 1
- Sentence 2
- Sentence 3 (correct answer)
- Sentence 4
Explanation: When you encounter questions about paragraph unity and relevance, you need to identify the main topic and determine which sentences support that central idea.
This paragraph focuses specifically on hibernation - what it is, how it works physiologically, and which animals use this survival strategy. Let's examine each sentence's connection to this main topic.
Sentence 3 is the correct answer because it discusses bird migration, which is a completely different winter survival strategy. While migration and hibernation are both ways animals cope with winter, migration involves active travel to warmer locations, whereas hibernation involves remaining in place and entering a dormant state. This sentence breaks the paragraph's focus and introduces an unrelated survival method.
Here's why the other choices are wrong: Sentence A provides the foundational definition of hibernation and establishes the paragraph's main topic, making it highly relevant. Sentence B explains the specific physiological changes that occur during hibernation (heart rate, breathing, temperature drops), directly supporting the main topic with crucial details. Sentence D gives concrete examples of hibernating animals and explains how they prepare (storing fat reserves), which reinforces the hibernation concept with real-world applications.
For paragraph unity questions on the SHSAT, always identify the main topic first, then check whether each sentence directly relates to and develops that specific concept. Watch out for sentences that discuss related but distinct topics - they're often the irrelevant choice, even if they seem thematically connected.
Question 16
(1) The Wright brothers, Orville and Wilbur, are credited with inventing, building, and flying the world's first successful motor-operated airplane. (2) On December 17, 1903, at Kitty Hawk, North Carolina, they made their first flight, forever changing the course of transportation. (3) The brothers' success was the culmination of years of meticulous research and experimentation with gliders. (4) The invention of the automobile in the late 19th century also had a profound impact on society.
Which sentence should be removed from the paragraph because it does not directly relate to the Wright brothers' achievement?
- Sentence 1
- Sentence 4 (correct answer)
- Sentence 3
- Sentence 2
Explanation: When you encounter questions about paragraph unity, you need to identify which sentences support the main topic and which ones stray from it. This paragraph is clearly focused on the Wright brothers and their historic flight achievement.
Let's examine how each sentence relates to this central theme. Sentence 1 introduces the Wright brothers as airplane inventors, establishing the main topic. Sentence 2 provides the specific details of their historic flight—the date, location, and significance. Sentence 3 explains the background work that led to their success, showing how years of research with gliders prepared them for this achievement. All three of these sentences directly connect to the Wright brothers' airplane invention.
However, sentence 4 shifts to discussing the automobile's invention in the late 19th century. While this might seem related because both airplanes and automobiles are transportation innovations, it doesn't directly support the paragraph's focus on the Wright brothers' specific achievement.
Looking at the wrong answers: Choice A (sentence 1) is incorrect because this sentence introduces the main topic. Choice C (sentence 3) is wrong because it provides essential background about their preparatory work with gliders. Choice D (sentence 2) is incorrect since it gives the crucial details of their historic first flight.
The correct answer is B because sentence 4 introduces an entirely different invention that, while historically significant, doesn't relate to the Wright brothers' story.
Strategy tip: When checking paragraph unity, ask yourself: "Does this sentence directly support or explain the main topic?" If it introduces unrelated information, it likely needs to be removed.
Question 17
(1) The Rosetta Stone, discovered in 1799, was the crucial key to deciphering ancient Egyptian hieroglyphs. (2) The stone features a decree inscribed in three different scripts: hieroglyphic, Demotic, and ancient Greek. (3) The British Museum in London, where the stone is displayed, attracts millions of visitors each year. (4) Because scholars could read ancient Greek, they were able to use that portion of the text to unlock the meaning of the previously incomprehensible hieroglyphic symbols.
Which sentence is least relevant to the paragraph's explanation of the Rosetta Stone's significance?
- Sentence 1
- Sentence 2
- Sentence 4
- Sentence 3 (correct answer)
Explanation: When you encounter questions about paragraph relevance, you need to identify the main focus and determine which details support that central idea versus which ones drift off-topic.
This paragraph's main purpose is explaining the Rosetta Stone's significance in deciphering hieroglyphs. Let's trace how each sentence contributes to this theme.
Sentence 1 establishes the stone's importance as "the crucial key to deciphering ancient Egyptian hieroglyphs" - this is the central claim. Sentence 2 explains why it was so valuable: it contained the same text in three scripts, including readable ancient Greek. Sentence 4 completes the logical chain by showing how scholars used the Greek text to decode the mysterious hieroglyphs.
However, sentence 3 shifts focus entirely. While it mentions where the stone is currently displayed and visitor numbers, this information doesn't help explain how or why the stone was significant for deciphering hieroglyphs. The British Museum's location and tourism statistics are interesting facts about the stone's present status, but they're irrelevant to understanding its historical breakthrough in linguistics.
Looking at the wrong choices: (A) Sentence 1 introduces the main topic, (B) Sentence 2 explains the stone's unique trilingual feature that made decipherment possible, and (C) Sentence 4 describes the actual process scholars used. All three directly support the paragraph's explanatory purpose.
For relevance questions, always ask yourself: "Does this sentence advance the paragraph's main argument or explanation?" Details about current museum displays, while factually accurate, often represent irrelevant tangents from the core academic focus.
Question 18
(1) Deserts are arid regions characterized by extremely low rainfall, receiving less than 10 inches per year. (2) Despite the harsh conditions, many specialized plants and animals have adapted to survive in these environments. (3) Cacti, for instance, have evolved to store water in their stems, while many desert animals are nocturnal to avoid the daytime heat. (4) Tropical rainforests, in contrast, receive heavy rainfall throughout the year and support immense biodiversity.
Which sentence should be removed to maintain the paragraph's focus on desert ecosystems?
- Sentence 1
- Sentence 2
- Sentence 3
- Sentence 4 (correct answer)
Explanation: When you encounter questions about paragraph unity and focus, you need to identify which sentence disrupts the main topic and doesn't belong with the others.
This paragraph's main focus is desert ecosystems - how they're defined and how life adapts to desert conditions. Sentence 4 breaks this focus by suddenly shifting to tropical rainforests, which are the complete opposite of deserts. While it creates a contrast, this comparison isn't developed or connected back to the desert theme, making it feel like an abrupt topic change that weakens the paragraph's coherence.
Let's examine why the other sentences belong: Sentence A establishes what deserts are by defining their key characteristic (low rainfall), which is essential for introducing the topic. Sentence B directly builds on this by explaining that despite harsh desert conditions, life has found ways to survive - this sets up the adaptation theme. Sentence C provides specific examples of these desert adaptations (water-storing cacti and nocturnal animals), which supports and illustrates the point made in sentence B.
Each of sentences A, B, and C works together to create a logical flow: definition → general adaptation concept → specific examples. Sentence D about tropical rainforests interrupts this flow and introduces information that doesn't advance the discussion of desert ecosystems.
For paragraph unity questions, always ask yourself: "Does this sentence support the main topic, or does it introduce a new, undeveloped idea?" Remove sentences that derail the focus, even if they contain interesting or related information.
Question 19
(1) The Industrial Revolution, which began in Great Britain in the late 18th century, was a period of major technological and socioeconomic change. (2) Key innovations, such as the steam engine and the power loom, transformed manufacturing processes from manual labor to machine-based production. (3) This shift led to the rise of the factory system and mass urbanization as people moved from rural areas to cities in search of work. (4) The agricultural revolution of the Neolithic period also dramatically changed human societies.
Which sentence is least relevant to the paragraph's topic of the Industrial Revolution?
- Sentence 1
- Sentence 4 (correct answer)
- Sentence 3
- Sentence 2
Explanation: When you encounter questions about paragraph relevance or unity, you need to identify the main topic and determine which sentences support that central theme versus which ones drift away from it.
This paragraph focuses specifically on the Industrial Revolution of the late 18th century. Let's examine how each sentence relates to this topic. Sentence 1 introduces the Industrial Revolution directly, establishing when and where it occurred and its significance. Sentence 2 provides concrete examples of Industrial Revolution innovations (steam engine, power loom) and explains how they changed manufacturing. Sentence 3 continues discussing the Industrial Revolution's effects, specifically the factory system and urbanization that resulted from these technological changes.
However, sentence 4 jumps to a completely different time period and event - the Neolithic agricultural revolution, which occurred thousands of years before the Industrial Revolution. While both were periods of significant change, the agricultural revolution is not relevant to a paragraph specifically about the Industrial Revolution of the late 18th century.
Choice A is wrong because sentence 1 directly introduces the paragraph's main topic. Choice C is incorrect because sentence 3 describes important consequences of the Industrial Revolution. Choice D is wrong because sentence 2 provides specific examples and mechanisms of Industrial Revolution changes.
When answering paragraph unity questions, look for the sentence that introduces a different time period, location, or concept that doesn't directly support the main topic. Often, these irrelevant sentences contain information that might be interesting or related to the general subject area, but they break the paragraph's focus.
Question 20
(1) The Supreme Court of the United States is the highest judicial body in the country and heads the judicial branch of government. (2) It consists of the Chief Justice and eight Associate Justices, who are nominated by the President and confirmed by the Senate. (3) The White House, where the President resides and works, is a major symbol of the executive branch. (4) The Court's primary function is to interpret the Constitution and federal law, and its decisions are final and binding on all other courts.
Which sentence should be removed to maintain the paragraph's specific focus on the Supreme Court?
- Sentence 1
- Sentence 3 (correct answer)
- Sentence 2
- Sentence 4
Explanation: This question tests your ability to identify sentences that don't belong in a focused paragraph. When evaluating paragraph unity, you need to determine the main topic and eliminate any sentences that stray from that central focus.
The paragraph's main topic is clearly the Supreme Court of the United States. Looking at each sentence, you can see that sentences 1, 2, and 4 all directly discuss the Supreme Court: sentence 1 introduces what it is, sentence 2 explains its composition and appointment process, and sentence 4 describes its primary function. These three sentences work together to provide a complete overview of the Supreme Court.
Sentence 3, however, shifts focus entirely to "The White House, where the President resides and works" and describes it as "a major symbol of the executive branch." While the President is mentioned earlier in the context of nominating justices, sentence 3 doesn't connect back to the Supreme Court at all—it's purely about the executive branch and the White House as a building and symbol.
Looking at the wrong answers: Choice A (sentence 1) is incorrect because it provides the essential introduction to the Supreme Court. Choice C (sentence 2) is wrong because it gives crucial information about the Court's composition. Choice D (sentence 4) is incorrect because it explains the Court's most important function.
When you encounter paragraph unity questions, identify the main topic first, then look for the sentence that introduces completely new information unrelated to that focus. The odd one out usually stands out clearly once you've established what the paragraph is truly about.
