Question 1
Origami, the Japanese art of paper folding, has a history as rich and complex as its intricate designs. The name itself comes from two Japanese words: ori, meaning "to fold," and kami, meaning "paper." While paper was invented in China, it was introduced to Japan by Buddhist monks in the sixth century. At first, paper was a rare and expensive luxury, so folded paper objects were used primarily for religious ceremonies and as special gifts.
Traditionally, origami is made from a single square sheet of paper without any cuts or glue. As paper became more affordable, origami evolved from a ceremonial art into a popular recreational activity. The crane is perhaps the most famous origami design, believed to grant a wish to anyone who folds one thousand of them.
In modern times, the principles of origami have been applied in surprising ways. Scientists and engineers use origami techniques to solve complex problems. For instance, these folding patterns have inspired the design of car airbags that deploy quickly and safely, solar panels for satellites that can be folded compactly for launch and then expanded in space, and tiny surgical instruments that can be inserted into the body and then unfolded to perform delicate operations.
The passage states that in its earliest days in Japan, origami was mainly used for
- creating popular recreational toys for children.
- religious events and as valuable presents. (correct answer)
- making the first forms of paper currency.
- teaching geometry concepts in local schools.
Explanation: The correct answer is B. The first paragraph states that because paper was a luxury, "folded paper objects were used primarily for religious ceremonies and as special gifts." Choice A describes what origami became later, once paper was more affordable. Choices C and D are plausible uses for paper or folding but are not mentioned in the passage.
Question 2
Bessie Coleman dreamed of flying when few women, and no African American women at all, were pilots. Born in Texas in 1892, she moved to Chicago as a young woman and heard exciting stories from pilots returning from World War I. Inspired, she decided she wanted to soar through the clouds, too. However, because she was both a woman and African American, no flight school in the United States would accept her.
Determined, Bessie did not give up. She saved her money, learned to speak French, and in 1920, she sailed to France. There, she was accepted into a well-known aviation school. In just seven months, she earned her international pilot's license, becoming the first woman of African American and Native American descent to do so.
Returning to the United States as a celebrity, "Queen Bess," as she was known, became a famous stunt pilot in airshows. She was known for her daring loops and dives. Yet, she used her fame for a purpose. She refused to perform anywhere that segregated Black and white audiences and dreamed of opening her own flight school to give other African Americans the chance to fly. Though her life was tragically cut short in a plane crash, her legacy of courage continues to inspire people today.
The passage states that Bessie Coleman made a rule for her airshow performances that she would not
- attempt the most dangerous stunts without more practice.
- fly in any planes that she considered to be unsafe.
- perform for audiences that were separated by race. (correct answer)
- appear in shows that were held in her home state of Texas.
Explanation: The correct answer is C. The last paragraph explicitly states, "She refused to perform anywhere that segregated Black and white audiences." Choices A and B are reasonable safety precautions for a stunt pilot but are not mentioned in the passage as her specific rule for performing. Choice D is not mentioned in the passage.
Question 3
Origami, the Japanese art of paper folding, has a history as rich and complex as its intricate designs. The name itself comes from two Japanese words: ori, meaning "to fold," and kami, meaning "paper." While paper was invented in China, it was introduced to Japan by Buddhist monks in the sixth century. At first, paper was a rare and expensive luxury, so folded paper objects were used primarily for religious ceremonies and as special gifts.
Traditionally, origami is made from a single square sheet of paper without any cuts or glue. As paper became more affordable, origami evolved from a ceremonial art into a popular recreational activity. The crane is perhaps the most famous origami design, believed to grant a wish to anyone who folds one thousand of them.
In modern times, the principles of origami have been applied in surprising ways. Scientists and engineers use origami techniques to solve complex problems. For instance, these folding patterns have inspired the design of car airbags that deploy quickly and safely, solar panels for satellites that can be folded compactly for launch and then expanded in space, and tiny surgical instruments that can be inserted into the body and then unfolded to perform delicate operations.
The passage provides an example of modern origami principles being used to design
- stronger building materials that resist earthquakes.
- more efficient engines for high-speed trains.
- compact satellite solar panels for space travel. (correct answer)
- artistic packaging for popular consumer products.
Explanation: The correct answer is C. The final paragraph lists several modern applications of origami, including "solar panels for satellites that can be folded compactly for launch and then expanded in space." Choices A, B, and D are all plausible applications of engineering or design principles, but they are not the specific examples mentioned in the text.
Question 4
A student tests which paper towel absorbs more water. She pours 50 milliliters of water into a cup. She dips Towel A into the water for 10 seconds. Then she repeats the same step with Towel B. Next, she measures the water left in the cup each time. Towel A leaves 20 milliliters, so it absorbs 30 milliliters.
What process is described in the text?
- Testing towel absorbency by measuring leftover water (correct answer)
- Growing plants by changing the soil type
- Building a bridge with sticks and glue
- Sorting rocks by color and size

Choice A is correct because it matches the specific information given in the passage about testing towel absorbency and measuring leftover water, demonstrating comprehension of explicit content. Choices B, C, and D are incorrect because they describe completely different activities not mentioned in the passage - the text only discusses testing paper towels, not plants, bridges, or rocks. To help students: Encourage practices like identifying action words and sequence markers, and teach students to match the answer choices with the main activity described in the passage. Watch for: Students getting distracted by familiar science activities rather than focusing on what is actually described.
Question 5
A student watches how salt affects ice melting. She places two equal ice cubes on separate plates. She sprinkles one teaspoon of salt on one cube. The other cube gets no salt at all. After five minutes, the salted cube has a larger puddle. The student records that salt speeds up melting.
What does the passage say about the salted ice cube?
- It melts faster and makes a larger puddle (correct answer)
- It freezes harder and becomes more solid
- It stays the same size after five minutes
- It turns into snow and blows away
Explanation: This question tests ISEE Lower Level reading comprehension skills: finding information stated directly in a passage. The key to answering this question is to identify and retrieve specific details mentioned explicitly in the text. This involves finding what the passage states about the salted ice cube's behavior. In this passage, the sentence 'After five minutes, the salted cube has a larger puddle' clearly describes what happens to the salted ice, allowing students to locate this information without inference. Choice A is correct because it matches the specific information given in the passage about the salted cube melting faster and creating a larger puddle, demonstrating comprehension of explicit content. Choices B, C, and D are incorrect because they describe outcomes that contradict or are not mentioned in the passage - the text specifically states the salted cube melted more, not less. To help students: Encourage practices like underlining comparison words and results in experiments, and teach students to match answer choices with the specific outcomes described. Watch for: Students selecting answers based on what they think might happen rather than what the passage explicitly states happened.
Question 6
In 1889, the Eiffel Tower opened in Paris, France. It was built for the World's Fair that year. The engineer Gustave Eiffel's company designed and constructed it. The tower is made of iron and stands about 1,063 feet tall. At first, some people disliked its look. Later, it became a famous symbol of Paris.
What is the name of the engineer in the passage?

This involves finding the engineer's name mentioned in connection with the Eiffel Tower. In this passage, the third sentence clearly states 'The engineer Gustave Eiffel's company designed and constructed it,' allowing students to locate this information without inference. Choice B is correct because it matches the specific name given in the passage for the engineer who designed the Eiffel Tower, demonstrating comprehension of explicit content. Choices A, C, and D are incorrect because they name other famous French figures who are not mentioned anywhere in this passage. To help students: Encourage practices like circling or highlighting proper names when they appear with job titles or descriptions, and teach students to link names with their roles as stated in the text. Watch for: Students selecting familiar French names they recognize rather than the specific name mentioned in the passage.
Question 7
Mount Everest is in the Himalaya Mountains in Asia. It sits on the border between Nepal and China. Everest is 29,032 feet tall. The air near the top has less oxygen. Many climbers use bottled oxygen to breathe. The climbing season is often in May, when winds are calmer.
Where is Mount Everest located, according to the passage?
- On the border between Nepal and China (correct answer)
- On the border between India and Pakistan
- On the border between France and Spain
- On the border between Canada and the United States
Explanation: This question tests ISEE Lower Level reading comprehension skills: finding information stated directly in a passage.

In this passage, the second sentence clearly states 'It sits on the border between Nepal and China,' allowing students to locate this information without inference. Choice A is correct because it matches the specific location given in the passage about Mount Everest being on the Nepal-China border, demonstrating comprehension of explicit content. Choices B, C, and D are incorrect because they name completely different border locations that are not mentioned in the passage. To help students: Encourage practices like paying attention to prepositions like 'between' that signal location information, and teach students to match geographic names exactly as they appear in the text. Watch for: Students selecting answers based on other famous mountain locations they may know rather than the specific information provided.
Question 8
In 1963, Dr. Martin Luther King Jr. led the March on Washington in Washington, D.C. The march happened on August 28, 1963, near the Lincoln Memorial. About 250,000 people attended to support civil rights. Dr. King gave his "I Have a Dream" speech that day. The march asked for equal rights and better jobs. It became a key moment in the civil rights movement.
Who is Dr. Martin Luther King Jr. mentioned in the passage?
- A scientist who discovered a new planet
- A leader who spoke at the March on Washington (correct answer)
- A singer who performed at a sports game
- A pilot who flew across the ocean alone
Explanation: This question tests ISEE Lower Level reading comprehension skills: finding information stated directly in a passage. The key to answering this question is to identify and retrieve specific details mentioned explicitly in the text. This involves understanding who Dr. Martin Luther King Jr. is based on the information provided. In this passage, the first sentence clearly identifies him as someone who 'led the March on Washington,' allowing students to locate this information without inference. Choice B is correct because it matches the specific information given in the passage about Dr. King being a leader who spoke at the March on Washington, demonstrating comprehension of explicit content. Choices A, C, and D are incorrect because they describe professions and achievements not mentioned in the passage - the text only discusses his role in the civil rights march. To help students: Encourage practices like identifying key verbs that describe what people did, and teach students to focus on the specific actions attributed to individuals in the passage. Watch for: Students selecting answers based on general knowledge about historical figures rather than the specific information provided.
Question 9
Honeybees live together in a hive with different jobs. One queen bee lays nearly all the eggs. Worker bees collect nectar and pollen from flowers. They also fan their wings to cool the hive. Drones are male bees that mate with the queen. A healthy hive can hold about 50,000 bees.
Based on the passage, how many bee types are named?
- Two
- Three (correct answer)
- Four
- Five
Explanation: This question tests ISEE Lower Level reading comprehension skills: finding information stated directly in a passage. The key to answering this question is to identify and retrieve specific details mentioned explicitly in the text. This involves counting the distinct types of bees mentioned in the passage. In this passage, three types are clearly named: 'queen bee' (sentence 2), 'Worker bees' (sentence 3), and 'Drones' (sentence 5), allowing students to count these without inference. Choice B is correct because it matches the specific count of three bee types explicitly named in the passage, demonstrating comprehension of explicit content. Choice C might seem tempting if students miscount, but only three distinct types are actually named. To help students: Encourage practices like making a quick list or tally marks while reading to keep track of items being counted, and teach students to look for specific naming words or phrases that introduce new categories. Watch for: Students counting individual bees or jobs rather than types, or missing one of the three categories mentioned.
Question 10
In 1903, Wilbur and Orville Wright tested a flying machine at Kitty Hawk, North Carolina. They chose this place because steady winds helped lift the plane. On December 17, 1903, their airplane made four short flights. The longest flight lasted 59 seconds and covered 852 feet. Five local men watched and helped move the plane between flights. The Wright brothers proved that powered flight could work.
According to the text, when did the flights happen?
- December 17, 1902
- December 17, 1903 (correct answer)
- July 4, 1903
- December 17, 1904
Explanation: This question tests ISEE Lower Level reading comprehension skills: finding information stated directly in a passage. The key to answering this question is to identify and retrieve specific details mentioned explicitly in the text. This involves scanning the passage for direct statements about the date of the Wright brothers' flights. In this passage, the date 'December 17, 1903' is clearly stated in the third sentence, allowing students to locate this information without inference. Choice B is correct because it matches the specific date given in the passage about when their airplane made four short flights, demonstrating comprehension of explicit content. Choice A is incorrect because it shows the wrong year (1902), which represents a common error of misreading dates or confusing similar numbers. To help students: Encourage practices like highlighting or underlining key facts such as dates and numbers, and teach students to focus on the exact wording in the passage to ensure accuracy. Watch for: Students assuming dates not present in the text or confusing similar-looking years.
Question 11
The Great Wall of China is not a single, continuous wall but a system of fortifications built over centuries. Construction began more than 2,000 years ago. The earliest sections were built by smaller states and were made of rammed earth—soil and gravel packed tightly between wooden frames. When Qin Shi Huang, the first Emperor of China, united the country in 221 BC, he had many of these existing walls connected to form a more unified defense against invasions from the north.
Later dynasties, especially the Ming Dynasty (1368-1644), did the most extensive building and repair work. The Ming-era sections are the most famous today, constructed with more durable materials like brick and stone. Along the wall, watchtowers were built at regular intervals. These towers served as barracks for soldiers and storage for supplies, but their most important function was as part of a signal system. Using smoke by day and fire by night, guards in the towers could quickly relay messages about enemy movements along the wall's length.
The passage states that the main purpose of the watchtowers along the wall was to
- provide permanent housing for soldiers' families.
- serve as a way to send messages quickly. (correct answer)
- act as trading posts for northern tribes.
- be the primary storage place for food and water.
Explanation: The correct answer is B. The second paragraph states that the watchtowers' "most important function was as part of a signal system...guards in the towers could quickly relay messages." While the passage also mentions they served as barracks and for storage (related to choice D), it explicitly calls the signal system their "most important function." Choices A and C are not mentioned in the text.
Question 12
Deep in the ocean, where sunlight cannot reach, many creatures create their own light. This phenomenon is called bioluminescence, and it is the result of a chemical reaction inside an organism's body. Unlike a light bulb, this process produces light with very little heat, which is why it is often called "cold light."
Animals in the deep sea use bioluminescence for many reasons. The anglerfish, for example, has a fleshy growth on its head that dangles a glowing lure in front of its mouth. Smaller fish are attracted to the light, swimming straight into the anglerfish's waiting jaws. Other creatures use bioluminescence for defense. Some types of squid and shrimp can release a cloud of glowing liquid to confuse a predator, allowing them to make a quick escape. Still others use patterns of light to communicate with each other, helping them find mates or warn others of danger in the pitch-black darkness.
The passage explains that the anglerfish uses its glowing lure for what purpose?
- To see its surroundings in the dark.
- To confuse predators and escape.
- To attract prey close to its mouth. (correct answer)
- To find a mate in the deep ocean.
Explanation: The correct answer is C. The passage explicitly states, "Smaller fish are attracted to the light, swimming straight into the anglerfish's waiting jaws." This clearly indicates the lure is for attracting prey. Choice B describes a defensive use of bioluminescence by squid and shrimp, not the anglerfish. Choices A and D are other uses of light, but the passage specifies the anglerfish's lure is for attracting prey.
Question 13
Deep in the ocean, where sunlight cannot reach, many creatures create their own light. This phenomenon is called bioluminescence, and it is the result of a chemical reaction inside an organism's body. Unlike a light bulb, this process produces light with very little heat, which is why it is often called "cold light."
Animals in the deep sea use bioluminescence for many reasons. The anglerfish, for example, has a fleshy growth on its head that dangles a glowing lure in front of its mouth. Smaller fish are attracted to the light, swimming straight into the anglerfish's waiting jaws. Other creatures use bioluminescence for defense. Some types of squid and shrimp can release a cloud of glowing liquid to confuse a predator, allowing them to make a quick escape. Still others use patterns of light to communicate with each other, helping them find mates or warn others of danger in the pitch-black darkness.
According to the passage, what is one way some sea creatures use bioluminescence for defense?
- By creating a glowing cloud to distract an attacker. (correct answer)
- By using a bright light to search for hiding places.
- By mimicking the lights of a larger, more dangerous animal.
- By attracting smaller fish to fight the predator for them.
Explanation: The correct answer is A. The passage states that some squid and shrimp "can release a cloud of glowing liquid to confuse a predator, allowing them to make a quick escape." This is a direct description of a defensive use. The other choices describe plausible but unmentioned defense mechanisms.
Question 14
The Great Wall of China is not a single, continuous wall but a system of fortifications built over centuries. Construction began more than 2,000 years ago. The earliest sections were built by smaller states and were made of rammed earth—soil and gravel packed tightly between wooden frames. When Qin Shi Huang, the first Emperor of China, united the country in 221 BC, he had many of these existing walls connected to form a more unified defense against invasions from the north.
Later dynasties, especially the Ming Dynasty (1368-1644), did the most extensive building and repair work. The Ming-era sections are the most famous today, constructed with more durable materials like brick and stone. Along the wall, watchtowers were built at regular intervals. These towers served as barracks for soldiers and storage for supplies, but their most important function was as part of a signal system. Using smoke by day and fire by night, guards in the towers could quickly relay messages about enemy movements along the wall's length.
According to the passage, the earliest parts of the wall were made primarily from what material?
- Packed soil and gravel. (correct answer)
- Large stones from nearby quarries.
- Durable bricks fired in kilns.
- Carved marble and granite.
Explanation: When you encounter reading comprehension questions asking about specific details, your job is to locate the exact information in the passage and match it to the answer choices without making assumptions.
The passage directly states that "The earliest sections were built by smaller states and were made of rammed earth—soil and gravel packed tightly between wooden frames." This clearly describes the construction material as packed soil and gravel, making choice (A) correct. The passage emphasizes these were the very first sections built over 2,000 years ago, before more advanced construction techniques were developed.
Let's examine why the other choices are wrong. Choice (B) mentions "large stones from nearby quarries," but the passage never mentions quarries or large stones for the earliest construction. Choice (C) refers to "durable bricks fired in kilns," but bricks are only mentioned in connection with the much later Ming Dynasty sections (1368-1644), not the earliest parts. Choice (D) suggests "carved marble and granite," which appears nowhere in the passage and would have been extremely expensive and impractical for ancient fortifications.
The passage actually creates a clear timeline contrast: early sections used simple rammed earth, while later dynasties like the Ming used "more durable materials like brick and stone."
Remember to pay attention to time markers in reading passages. Words like "earliest," "later," and "first" help you distinguish between different periods and avoid mixing up details from different time frames. Always match your answer to the specific time period the question asks about.
Question 15
The Great Wall of China is not a single, continuous wall but a system of fortifications built over centuries. Construction began more than 2,000 years ago. The earliest sections were built by smaller states and were made of rammed earth—soil and gravel packed tightly between wooden frames. When Qin Shi Huang, the first Emperor of China, united the country in 221 BC, he had many of these existing walls connected to form a more unified defense against invasions from the north.
Later dynasties, especially the Ming Dynasty (1368-1644), did the most extensive building and repair work. The Ming-era sections are the most famous today, constructed with more durable materials like brick and stone. Along the wall, watchtowers were built at regular intervals. These towers served as barracks for soldiers and storage for supplies, but their most important function was as part of a signal system. Using smoke by day and fire by night, guards in the towers could quickly relay messages about enemy movements along the wall's length.
Which leader, according to the passage, was responsible for connecting many of the earlier walls?
- A leader from the Ming Dynasty.
- A guard from a watchtower.
- A ruler of one of the smaller states.
- The first Emperor, Qin Shi Huang. (correct answer)
Explanation: When you encounter reading comprehension questions asking about specific historical facts or details, focus on scanning the passage for key names, dates, and actions rather than trying to remember everything.
The passage clearly states that "When Qin Shi Huang, the first Emperor of China, united the country in 221 BC, he had many of these existing walls connected to form a more unified defense against invasions from the north." This directly answers the question about which leader connected the earlier walls, making D) The first Emperor, Qin Shi Huang the correct answer.
Let's examine why the other choices don't work. A) A leader from the Ming Dynasty is incorrect because the passage explains that the Ming Dynasty (1368-1644) did "extensive building and repair work" but doesn't mention them connecting earlier walls—that happened much earlier with Qin Shi Huang in 221 BC. B) A guard from a watchtower is wrong because guards were mentioned only in relation to operating the signal system with smoke and fire, not connecting walls. C) A ruler of one of the smaller states is incorrect because these rulers built the original separate sections that later needed connecting—they didn't do the connecting themselves.
For ISEE reading comprehension questions like this, use the "scan and match" strategy: identify the key term in the question (in this case, "connecting walls"), then scan the passage for that specific action. Don't rely on your outside knowledge of history—stick strictly to what the passage tells you, and look for direct statements rather than making inferences.
Question 16
A dog's tail is much more than just an appendage; it is a vital tool for balance and communication. When a dog runs and needs to make a sudden, sharp turn, its tail acts as a counterbalance, much like a tightrope walker's pole. By throwing its tail in the opposite direction of the turn, the dog can maintain its stability and prevent itself from spinning out. In the water, a dog's tail functions like a rudder on a boat, helping it to steer as it paddles.
Beyond its physical uses, the tail is a key part of a dog's language. The speed and position of its wag can signal different emotions. A high, gently wagging tail often shows a dog is relaxed and happy. A tail held high and stiff might indicate alertness or aggression. In contrast, a low tail tucked between the legs is a clear sign of fear or submission. By observing a dog's tail, we can get a better understanding of what it is feeling.
What does the passage identify as a sign of fear communicated by a dog's tail?
- A high, stiffly held tail.
- A gently wagging tail.
- A tail pointing straight out.
- A tail tucked between the legs. (correct answer)
Explanation: When you encounter reading comprehension questions about specific details, your goal is to locate the exact information in the passage rather than making inferences or relying on general knowledge.
The passage explicitly states that "a low tail tucked between the legs is a clear sign of fear or submission." This directly matches answer choice D, making it the correct answer. The key word "tucked" describes the specific position that indicates fear.
Let's examine why the other options are incorrect. Choice A describes "a high, stiffly held tail," but the passage says this "might indicate alertness or aggression" — the opposite of fear. Choice B mentions "a gently wagging tail," which the passage associates with a dog that is "relaxed and happy," again not fear. Choice C refers to "a tail pointing straight out," but this position isn't mentioned anywhere in the passage as communicating any emotion.
Notice how each wrong answer either represents a different emotion described in the passage or introduces information not found in the text at all. This is a common pattern in reading comprehension questions — distractors often mix up details from the passage or add plausible-sounding but incorrect information.
For detail questions like this one, always scan the passage for the specific information being asked about rather than trying to remember what you think you know about the topic. Circle or underline key phrases when you find them to confirm your answer matches the text exactly.
Question 17
In 79 AD, the bustling Roman city of Pompeii was frozen in time. The nearby volcano, Mount Vesuvius, erupted violently, burying the city and its inhabitants under a thick blanket of volcanic ash and pumice. The eruption was so sudden that most people were caught in the middle of their daily lives. For nearly 1,700 years, the city lay hidden and forgotten.
When archaeologists began to excavate Pompeii in the 18th century, they found a remarkably preserved city. Buildings, artwork, and everyday objects were all intact, providing a unique snapshot of Roman life. One of the most fascinating discoveries was made by noticing voids in the hardened ash layers. As the bodies of victims decomposed over time, they left hollow spaces. Archaeologists carefully poured liquid plaster into these cavities. Once the plaster hardened, they chipped away the surrounding ash to reveal detailed casts of the people of Pompeii, capturing their final moments.
The passage states that Pompeii was preserved for centuries under layers of what material?
- Slow-moving lava and rock.
- Packed dirt from a landslide.
- Thick mud and floodwater.
- Volcanic ash and pumice. (correct answer)
Explanation: This question tests your ability to locate specific factual information directly stated in a passage. When you encounter detail-oriented questions like this, you should scan the text for key terms from the question.
The passage explicitly states that Mount Vesuvius "burying the city and its inhabitants under a thick blanket of volcanic ash and pumice." This direct quote gives you the exact materials that preserved Pompeii for centuries.
Looking at why the incorrect answers don't work: Choice A mentions "slow-moving lava and rock," but the passage never mentions lava at all, and there's no indication the materials moved slowly. Choice B suggests "packed dirt from a landslide," but the passage clearly identifies this as a volcanic eruption, not a landslide, and specifies ash and pumice rather than dirt. Choice C proposes "thick mud and floodwater," but again, the passage describes a volcanic event with dry materials (ash and pumice), not water-related materials.
The correct answer is D because it matches the passage's exact wording about the volcanic materials that buried and preserved the city.
For reading comprehension questions asking for specific details, always look for direct textual evidence rather than making inferences. The ISEE often includes wrong answers that sound plausible but aren't supported by the text. Train yourself to find the exact words or phrases that answer the question, just like "volcanic ash and pumice" appears word-for-word in this passage.
Question 18
In 79 AD, the bustling Roman city of Pompeii was frozen in time. The nearby volcano, Mount Vesuvius, erupted violently, burying the city and its inhabitants under a thick blanket of volcanic ash and pumice. The eruption was so sudden that most people were caught in the middle of their daily lives. For nearly 1,700 years, the city lay hidden and forgotten.
When archaeologists began to excavate Pompeii in the 18th century, they found a remarkably preserved city. Buildings, artwork, and everyday objects were all intact, providing a unique snapshot of Roman life. One of the most fascinating discoveries was made by noticing voids in the hardened ash layers. As the bodies of victims decomposed over time, they left hollow spaces. Archaeologists carefully poured liquid plaster into these cavities. Once the plaster hardened, they chipped away the surrounding ash to reveal detailed casts of the people of Pompeii, capturing their final moments.
What did archaeologists pour into the hollow voids in the ash, according to the passage?
- A special type of clear resin.
- Liquid plaster that would harden. (correct answer)
- Hot wax to make molds.
- A chemical to preserve the space.
Explanation: The correct answer is B. The second paragraph states, "Archaeologists carefully poured liquid plaster into these cavities." The other choices are plausible materials for making casts or preserving things, but the passage specifically names plaster as the substance used.
Question 19
The Atacama Desert in Chile is one of the most extreme environments on Earth. It is known as the driest non-polar desert in the world. Scientific evidence suggests that some weather stations in the Atacama have never recorded rainfall, and certain riverbeds appear to have been dry for 120,000 years. This extreme dryness is caused by two main factors: it sits in the "rain shadow" of the Andes Mountains to the east, which blocks moisture from the Amazon basin, and a cold ocean current offshore creates conditions that prevent rain from forming.
Despite these harsh conditions, life finds a way. Some plants and animals have adapted to get moisture from a thick coastal fog, known as the camanchaca, that rolls in from the Pacific Ocean. Hardy microorganisms also live in the soil, surviving on the smallest traces of water.
The Atacama's unique environment makes it valuable for scientists. Its clear, unpolluted skies and high altitude provide perfect conditions for astronomy. Major observatories with some of the world's most powerful telescopes are located there, allowing astronomers to peer deep into the universe.
According to the passage, the Atacama's suitability for astronomy is due to its
- minimal rainfall and hardy microorganisms.
- valuable soil and unique coastal fog.
- high elevation and cloudless, clean air. (correct answer)
- position in a rain shadow and offshore ocean currents.
Explanation: The correct answer is C. The last paragraph explicitly states, "Its clear, unpolluted skies and high altitude provide perfect conditions for astronomy." Choices A and B mention details from the passage (microorganisms, fog) that are true of the desert but are not related to why it is good for astronomy. Choice D lists the reasons for the desert's dryness, not its value for astronomy, which is a subtle distinction designed to trap readers who don't read the question carefully.
Question 20

In contrast, a low tail tucked between the legs is a clear sign of fear or submission. By observing a dog's tail, we can get a better understanding of what it is feeling.
The passage mentions that a dog's tail helps with balance particularly when the dog is
- standing still on a slippery surface.
- jumping over a high obstacle.
- digging a hole in the ground.
- making a quick turn while running. (correct answer)
Explanation: When you encounter reading comprehension questions that ask about specific details, your job is to locate the exact information in the passage and match it to the answer choices.
The passage clearly states that when a dog "runs and needs to make a sudden, sharp turn, its tail acts as a counterbalance, much like a tightrope walker's pole." It explains that by throwing its tail in the opposite direction of the turn, the dog maintains stability and prevents spinning out. This directly supports answer choice D - the tail helps with balance when making a quick turn while running.
Let's examine why the other options are incorrect. Choice A suggests standing still on a slippery surface, but the passage specifically discusses the tail's role during movement, not stationary positions. Choice B mentions jumping over obstacles, which isn't addressed anywhere in the text. Choice C refers to digging holes, which also has no connection to the balance function described in the passage.
The passage focuses on two specific scenarios where the tail aids balance: sharp turns while running (like a tightrope walker's pole) and steering while swimming (like a boat's rudder). Only answer choice D matches one of these explicitly mentioned situations.
For reading comprehension questions like this, always return to the text to find the specific evidence that supports your answer. Don't rely on outside knowledge about dogs - stick to what the passage actually tells you. Look for key phrases that directly connect to the answer choices.
