Explicit Detail Retrieval - SSAT Upper Level Reading

1. Read the passage, then answer the question. In 1716, English writer Lady Mary Wortley Montagu traveled to the Ottoman Empire when her husband was appointed ambassador to Constantinople. While living there, she observed a local practice used to prevent smallpox. The method involved introducing material from a mild smallpox case into a healthy person, a procedure later called variolation. Montagu had personal reasons to pay attention to smallpox prevention. She had survived smallpox earlier and bore facial scars from the disease. In Constantinople, she arranged for her son to undergo variolation in 1718, under the supervision of local practitioners. After returning to England, Montagu promoted the procedure among aristocratic circles. In 1721, during a smallpox outbreak in London, variolation was tested more formally. Montagu also arranged for her daughter to be variolated in England, increasing public interest. Variolation carried risks, but it influenced later medical developments. In 1796, Edward Jenner introduced vaccination using cowpox, which proved safer and became the foundation of modern immunization. Question: According to the passage, in what year did Montagu arrange variolation for her son?
   Answer: 1718 This question tests SSAT Upper Level reading skills: locating explicit details in a text. This skill involves identifying information directly stated in the passage, which requires careful reading and comprehension of explicit details. In this passage, details such as the year Montagu arranged variolation for her son are clearly stated, helping readers understand the timeline of her promotion of the practice. The correct choice, B, is correct because it directly reflects the passage's information about the variolation occurring in 1718. A common distractor, A, is incorrect because it refers to her travel year of 1716, not the variolation date. To help students, emphasize strategies such as highlighting key details while reading, summarizing paragraphs to capture explicit information, and distinguishing between explicitly stated and inferred information. Encourage practice with passages that include both explicit and implicit information to strengthen detail retrieval skills.
2. Read the passage, then answer the question. Jane Addams was born on September 6, 1860, in Cedarville, Illinois. Her father, John H. Addams, served as a state senator, and her family valued public service. Addams attended the Rockford Female Seminary (later Rockford College) and graduated in 1881. After graduation, she traveled in Europe and read widely about poverty and labor conditions. In 1889, Addams and her friend Ellen Gates Starr founded Hull House in Chicago. They established it in a large, older home on Halsted Street. Hull House offered practical services: English classes for immigrants, a day nursery for working families, and clubs for youth. Addams also helped create public playgrounds and supported reforms in sanitation and housing. She wrote about her experiences in "Twenty Years at Hull-House," published in 1910. Addams became a prominent voice for peace during World War I. In 1915, she served as president of the Women's International League for Peace and Freedom. Her public opposition to war was controversial, yet she continued to argue for negotiation and international cooperation. In recognition of her work, Addams received the Nobel Peace Prize in 1931. Jane Addams died on May 21, 1935, but Hull House and her writings continued to influence social work and civic reform in the United States. What does the passage explicitly mention about the location of Hull House?
   Answer: It was on Halsted Street in Chicago This question tests SSAT Upper Level reading skills: locating explicit details in a text. This skill involves identifying information directly stated in the passage, which requires careful reading and comprehension of explicit details. In this passage, details such as the specific location of Hull House are clearly stated, helping readers understand where this important institution was established. The correct choice, A (It was on Halsted Street in Chicago), is correct because it directly reflects the passage's information about Hull House's location, as stated in 'They established it in a large, older home on Halsted Street.' A common distractor, C (It was in Cedarville, Illinois), is incorrect because it confuses Jane Addams' birthplace with the location of Hull House. To help students, emphasize strategies such as mapping different locations mentioned in biographical passages, distinguishing between birthplaces and work locations, and paying attention to prepositions that indicate location. Encourage practice with passages that mention multiple places to strengthen detail retrieval skills.
3. What specific percentages and time measurements does the passage provide regarding code-switching patterns and vocabulary incorporation in Llanito?
   Answer: Code-switching occurs 12.3 times per minute, English comprises 40% of vocabulary, and borrowed words use English vowels 73% of the time When you encounter reading comprehension questions asking for specific numerical data, your task is to locate and match exact figures from the passage without getting confused by similar numbers or making assumptions. The passage provides three key measurements about Llanito's linguistic characteristics. First, code-switching occurs at a rate of 12.3 instances per minute in casual discourse. Second, English vocabulary comprises approximately 40% of Llanito. Third, phonetic analysis shows that 73% of borrowed vocabulary adopts English vowel sounds while maintaining Spanish consonant structures. Choice A correctly identifies all three statistics: 12.3 times per minute for code-switching, 40% English vocabulary, and 73% vowel adaptation in borrowed words. This matches the passage exactly. Choice B contains fabricated numbers not found anywhere in the text—14.2 times per minute, 45% vocabulary, and 75% phonetic adaptation. These are plausible-sounding figures designed to trap students who don't carefully verify each statistic. Choice C also uses invented data: 11.8 times per minute, 38% vocabulary, and 70% vowel modification. Again, these numbers seem reasonable but don't appear in the original passage. Choice D correctly states the code-switching rate (12.3 times per minute) and vowel adaptation percentage (73%), but incorrectly claims English vocabulary comprises 42% rather than the stated 40%. For numerical detail questions like this, always return to the passage to verify each figure rather than relying on memory. Wrong answers often use numbers that are close to but not identical to the correct data, testing your precision in reading comprehension.
4. Read the passage, then answer the question. In 1492, the Spanish monarchs King Ferdinand and Queen Isabella agreed to support the voyage of Christopher Columbus, an Italian navigator. Columbus sailed from Palos de la Frontera in Spain on August 3, 1492, with three ships: the Niña, the Pinta, and the Santa María. After weeks at sea, the expedition reached land on October 12, 1492. Columbus named the island San Salvador. The voyage continued through parts of the Caribbean, and the Santa María later ran aground. Columbus left some men at a settlement called La Navidad. Columbus returned to Spain in early 1493 and reported that he had reached islands near Asia. In later years, Europeans recognized that the voyages had connected Europe to the Americas in a sustained way. Columbus made additional voyages, but the first voyage remained the most famous because it marked the initial landing in 1492. Question: According to the passage, what were the names of Columbus's three ships?
   Answer: Niña, Pinta, and Santa María This question tests SSAT Upper Level reading skills: locating explicit details in a text. This skill involves identifying information directly stated in the passage, which requires careful reading and comprehension of explicit details. In this passage, details such as the names of Columbus's ships are clearly stated, helping readers understand the logistics of his voyage. The correct choice, A, is correct because it directly reflects the passage's information about the ships being Niña, Pinta, and Santa María. A common distractor, E, is incorrect because it replaces Santa María with La Navidad, which was a settlement, not a ship. To help students, emphasize strategies such as highlighting key details while reading, summarizing paragraphs to capture explicit information, and distinguishing between explicitly stated and inferred information. Encourage practice with passages that include both explicit and implicit information to strengthen detail retrieval skills.
5. What is the approximate size of the Sahara Desert?
   Answer: Approximately 3.6 million square miles across North Africa The passage clearly states that 'The Sahara Desert covers approximately 3.6 million square miles across North Africa.' Choice B (2.5 million) incorrectly uses the population figure. Choices C (4.2 million) and D (3.0 million) provide areas not mentioned in the passage.
6. Read the passage, then answer the question. In April 1970, the damaged spacecraft Apollo 13 became the focus of an urgent rescue effort led by NASA's Mission Control in Houston, Texas. The mission had launched from Kennedy Space Center on April 11, 1970, carrying three astronauts: James A. Lovell, John L. "Jack" Swigert, and Fred W. Haise. Their original goal was to land on the Moon near the Fra Mauro region. On the evening of April 13, 1970, about 56 hours into the flight, an oxygen tank in the service module exploded. The crew reported the emergency at 9:08 p.m. Houston time. The explosion caused a rapid loss of oxygen and electrical power, making a lunar landing impossible. Mission Control immediately directed the astronauts to use the lunar module, Aquarius, as a "lifeboat." To conserve power, the crew shut down most systems in the command module, Odyssey, and moved essential operations into Aquarius. Engineers on the ground developed procedures to reduce carbon dioxide buildup by adapting square filters to fit round openings. They also planned a return path that used a free-return trajectory around the Moon. Apollo 13 swung behind the Moon on April 15, 1970, and then fired its engines to adjust its course home. The spacecraft re-entered Earth's atmosphere on April 17, 1970, and the astronauts splashed down safely in the Pacific Ocean. Navy recovery forces reached the crew soon after landing. Although the mission did not land on the Moon, NASA later described Apollo 13 as a "successful failure" because the crew returned alive. Question: The passage clearly states that the oxygen tank exploded when?
   Answer: on April 13, 1970, about 56 hours into flight This question tests SSAT Upper Level reading skills: locating explicit details in a text. This skill involves identifying information directly stated in the passage, which requires careful reading and comprehension of explicit details. In this passage, details such as the date and time of the oxygen tank explosion are clearly stated, helping readers understand the timeline of the Apollo 13 mission crisis. The correct choice, B, is correct because it directly reflects the passage's information about the explosion occurring on April 13, 1970, about 56 hours into the flight. A common distractor, E, is incorrect because it alters a key detail by changing the time to 9:08 a.m. instead of 9:08 p.m. as stated in the passage. To help students, emphasize strategies such as highlighting key details while reading, summarizing paragraphs to capture explicit information, and distinguishing between explicitly stated and inferred information. Encourage practice with passages that include both explicit and implicit information to strengthen detail retrieval skills.
7. Read the passage, then answer the question. In December 1955, the Montgomery Bus Boycott began in Montgomery, Alabama, after the arrest of Rosa Parks. On December 1, 1955, Parks, a seamstress and NAACP member, refused to give up her seat to a white passenger on a city bus. Police arrested her, and she was charged with violating the city's segregation ordinance. Local leaders quickly organized a response. On December 5, 1955, the Montgomery Improvement Association (MIA) was formed to coordinate a boycott of the city bus system. That same day, a young minister, Martin Luther King Jr., was elected president of the MIA. The boycott relied on carpools, walking, and community fundraising. Many participants walked long distances to work and school, and churches served as meeting places for planning and updates. The boycott lasted 381 days. During that time, King's home was bombed, and several leaders were arrested, yet the organizers continued to insist on nonviolent protest. The legal challenge moved through federal courts. On November 13, 1956, the U.S. Supreme Court affirmed a lower court decision declaring bus segregation unconstitutional. The official order reached Montgomery soon after. On December 21, 1956, Montgomery's buses were integrated, and Black riders could sit where they chose. The boycott became a widely reported example of coordinated, nonviolent civil rights action and helped establish King as a national leader. The passage clearly states that the boycott lasted how many days?
   Answer: 381 days This question tests SSAT Upper Level reading skills: locating explicit details in a text. This skill involves identifying information directly stated in the passage, which requires careful reading and comprehension of explicit details. In this passage, details such as the specific duration of the Montgomery Bus Boycott are clearly stated, helping readers understand the timeline of this historic civil rights action. The correct choice, B (381 days), is correct because it directly reflects the passage's information about the boycott's duration, as stated in 'The boycott lasted 381 days.' A common distractor, A (365 days), is incorrect because it assumes the boycott lasted exactly one year, which is a reasonable but inaccurate approximation. To help students, emphasize strategies such as highlighting specific durations and time periods while reading, calculating time spans when given start and end dates, and distinguishing between approximate and exact figures. Encourage practice with passages that include various time measurements to strengthen detail retrieval skills.
8. According to the passage, what were the specific dates mentioned for key milestones in the World Wide Web's development?
   Answer: Berners-Lee's proposal was submitted in March 1989, the first web server activated December 25, 1990, and the first website launched August 6, 1991 When you encounter reading comprehension questions asking for specific dates or details, you're being tested on your ability to locate and accurately extract factual information from the passage. These questions require careful attention to precise wording and numbers. Looking at the passage systematically, you can find three key dates mentioned for major milestones: Berners-Lee's original proposal was "submitted in March 1989," the first web server "was activated on December 25, 1990," and "The first website, info.cern.ch, went online on August 6, 1991." Choice A correctly captures all three of these dates exactly as stated in the passage. Choice B changes the proposal month to February instead of March, alters the server activation date to December 20 instead of December 25, and shifts the website launch to August 8 instead of August 6. Choice C incorrectly states the proposal was submitted in April rather than March, moves the server activation to January 1, 1991 instead of December 25, 1990, and changes the website date to July 6 instead of August 6. Choice D keeps the proposal date correct but shifts both the server activation and website launch dates forward by exactly one year each—December 25, 1991 and August 6, 1992. For detail-oriented questions like this, always return to the passage to verify each piece of information rather than relying on memory. The incorrect choices often use plausible-sounding dates that are close to the actual ones, designed to catch students who skim or misremember specific details.
9. Read the passage, then answer the question. In 2003, engineers completed the Three Gorges Dam on the Yangtze River in China as part of a long-term hydroelectric and flood-control project. Construction began earlier, but the passage of time is important: the dam's first generator began producing electricity in July 2003. The project was managed by the China Three Gorges Corporation, and the dam's power station was designed to supply electricity to major industrial regions. The dam spans the river near the city of Yichang in Hubei Province. It includes a large concrete wall, ship locks, and a ship lift intended to help vessels move past the dam. The reservoir created behind the dam extends upstream, and its water level is controlled to reduce flooding during heavy rain seasons. Engineers also planned for sediment management because the Yangtze carries significant silt. The hydroelectric station eventually included 32 main turbines, each rated at 700 megawatts, along with 2 smaller units that provide power for the dam's own operations. When all main turbines operate, the station's total main generating capacity is 22,400 megawatts. The electricity is transmitted through high-voltage lines to cities and factories. The project required relocating residents from areas that would be submerged by the reservoir. Government reports listed new housing developments and compensation policies, and the relocation occurred in stages. Supporters emphasized electricity production and flood control, while critics raised concerns about environmental change and the loss of cultural sites. According to the passage, how many main turbines were eventually included at the station?
   Answer: 32 main turbines This question tests SSAT Upper Level reading skills: locating explicit details in a text. This skill involves identifying information directly stated in the passage, which requires careful reading and comprehension of explicit details. In this passage, details such as the specific number of turbines at the Three Gorges Dam are clearly stated, helping readers understand the scale of this engineering project. The correct choice, B (32 main turbines), is correct because it directly reflects the passage's information about the turbine count, as stated in 'The hydroelectric station eventually included 32 main turbines.' A common distractor, C (34 main turbines), is incorrect because it adds the 2 smaller units mentioned for the dam's operations to the 32 main turbines. To help students, emphasize strategies such as distinguishing between different categories of items (main turbines vs. smaller units), paying attention to qualifying words like 'main' or 'additional,' and creating lists to organize different numerical details. Encourage practice with passages that include multiple related numbers to strengthen detail retrieval skills.
10. Read the passage, then answer the question. In 1905, author Upton Sinclair moved to Chicago to research the meatpacking industry for a novel. He spent seven weeks gathering information by visiting packinghouses and speaking with workers. Sinclair wrote much of the book while living in a small rented room, and he aimed to depict the harsh conditions faced by immigrant laborers. The resulting novel, "The Jungle," was published in 1906. The story follows Jurgis Rudkus, a Lithuanian immigrant who arrives in Chicago with his family and finds work in the stockyards. Sinclair described long hours, unsafe machinery, and a workplace where injuries were common. He also included explicit descriptions of contaminated meat and careless sanitation, details that alarmed many readers. Public reaction was swift. President Theodore Roosevelt read the book and ordered an investigation. In response to the findings and public pressure, Congress passed the Meat Inspection Act and the Pure Food and Drug Act, both in 1906. These laws increased federal oversight of meatpacking and required more accurate labeling of food and medicines. Sinclair later remarked that he had aimed at the public's heart but had hit its stomach instead, meaning that readers focused more on food safety than on workers' rights. Although the novel is fiction, its publication is often linked to major changes in American consumer protection. According to the passage, what was the name of the novel published in 1906?
    Answer: "The Jungle" This question tests SSAT Upper Level reading skills: locating explicit details in a text. This skill involves identifying information directly stated in the passage, which requires careful reading and comprehension of explicit details. In this passage, details such as the title of Sinclair's novel are clearly stated, helping readers understand the specific work being discussed. The correct choice, A ('The Jungle'), is correct because it directly reflects the passage's information about the novel's title, as stated in 'The resulting novel, "The Jungle," was published in 1906.' A common distractor, E ('Jurgis Rudkus'), is incorrect because it names the main character of the novel rather than the novel itself. To help students, emphasize strategies such as distinguishing between titles, character names, and other proper nouns, paying attention to quotation marks that indicate titles, and organizing different types of names mentioned in literary passages. Encourage practice with passages about books and authors to strengthen detail retrieval skills.
11. What specific workforce numbers and mortality statistics does the passage provide for both the French and American construction periods?
    Answer: The French period resulted in 22,000 deaths, while Americans employed 56,000 workers and achieved mortality reduction from 176 to under 6 per 1,000 When you encounter detail-heavy reading passages on the SSAT, questions often test your ability to locate and accurately combine specific facts scattered throughout the text. This question requires you to identify precise workforce numbers and mortality statistics from both construction periods. The passage provides clear data for both phases: The French attempt (1881-1889) resulted in approximately 22,000 deaths, primarily from disease. The American effort employed a peak workforce of 56,000 workers representing 97 nationalities. Dr. Gorgas's revolutionary disease control measures reduced mortality rates from 176 deaths per 1,000 workers annually to fewer than 6 deaths per 1,000 workers by 1906. Answer choice D correctly captures all these specific figures. Answer A omits the crucial French death toll of 22,000, providing incomplete information about the French period. Answer B contains multiple factual errors: it changes the American workforce from 56,000 to 52,000 and alters the final mortality rate from "fewer than 6" to "below 8." Answer C also introduces inaccuracies, reducing French deaths from "approximately 22,000" to "about 20,000" and inflating the initial mortality rate from 176 to "exceeding 180." On SSAT reading comprehension, pay close attention to precise numerical details when they appear prominently in passages. The test makers often create wrong answers by slightly altering these figures or omitting key data points. Always double-check that your chosen answer includes all the specific information requested in the question stem.
12. Read the passage, then answer the question. In 1911, Norwegian explorer Roald Amundsen led an expedition to become the first person to reach the South Pole. Amundsen kept his plans unusually secret at first. Although he had previously discussed traveling to the North Pole, he changed his goal after learning that other explorers claimed to have arrived there. On June 3, 1910, Amundsen's ship, the Fram, departed from Oslo, Norway, carrying supplies, sledges, and a large number of dogs intended for pulling. The expedition established its main base, Framheim, on the Ross Ice Shelf in January 1911. Amundsen chose this location because it was closer to the Pole than some rival bases. During the Antarctic winter, the team prepared equipment and mapped routes. They also created supply depots at measured distances so the return journey would not depend on luck. Amundsen insisted that each depot be clearly marked with tall flags so it could be found even in poor visibility. On October 19, 1911, Amundsen set out for the Pole with four companions: Olav Bjaaland, Helmer Hanssen, Sverre Hassel, and Oscar Wisting. They traveled with five sledges and fifty-two dogs. The route crossed the Transantarctic Mountains through a glacier that Amundsen named Axel Heiberg Glacier, honoring a supporter of the expedition. The party moved steadily, measuring distances and checking their compass readings. On December 14, 1911, the team reached the South Pole and planted the Norwegian flag. Amundsen left a tent and a letter in case another expedition arrived later. The group returned to Framheim without losing a man, arriving back at base on January 25, 1912. Amundsen announced his success after returning to civilization, and the achievement immediately became a milestone in polar exploration. According to the passage, what was the name of Amundsen's Antarctic base?
    Answer: Framheim This question tests SSAT Upper Level reading skills: locating explicit details in a text. This skill involves identifying information directly stated in the passage, which requires careful reading and comprehension of explicit details. In this passage, details such as the name of Amundsen's base 'Framheim' are clearly stated, helping readers understand the specific locations and terminology used in the expedition. The correct choice, A (Framheim), is correct because it directly reflects the passage's information about Amundsen's main base, as stated in 'The expedition established its main base, Framheim, on the Ross Ice Shelf in January 1911.' A common distractor, C (Axel Heiberg Camp), is incorrect because Axel Heiberg was the name of a glacier, not a base or camp. To help students, emphasize strategies such as underlining proper nouns and location names while reading, creating lists of key terms mentioned in the passage, and distinguishing between different types of locations (bases, glaciers, cities). Encourage practice with passages that include multiple geographic references to strengthen detail retrieval skills.
13. Read the passage, then answer the question. In September 1666, the Great Fire of London destroyed large sections of the city. The fire began in a bakery on Pudding Lane in the early hours of Sunday, September 2, 1666. The bakery belonged to Thomas Farriner, who supplied bread to the king's navy. A strong wind helped the flames spread quickly through wooden buildings and narrow streets. The fire burned for four days, moving westward from the area near London Bridge. Many residents fled on foot or by boat, carrying what belongings they could. The fire destroyed St. Paul's Cathedral, along with thousands of houses, shops, and churches. Contemporary estimates reported that about 13,200 houses were lost. Despite the enormous property damage, official records listed only a small number of deaths. After the fire, London faced the task of rebuilding. New regulations encouraged the use of brick and stone instead of wood. The architect Sir Christopher Wren proposed ambitious redesigns for the city, though many streets were rebuilt along older lines because property boundaries were difficult to change. By the late 1660s and into the following decades, London gradually recovered. The disaster, however, remained a defining event in the city's history and influenced building practices for generations. Question: According to the passage, the Great Fire began in a bakery on which street?
    Answer: Pudding Lane This question tests SSAT Upper Level reading skills: locating explicit details in a text. This skill involves identifying information directly stated in the passage, which requires careful reading and comprehension of explicit details. In this passage, details such as the street where the Great Fire began are clearly stated, helping readers understand the origin of the disaster. The correct choice, C, is correct because it directly reflects the passage's information about the fire starting in a bakery on Pudding Lane. A common distractor, A, is incorrect because it invents a street name not mentioned in the passage. To help students, emphasize strategies such as highlighting key details while reading, summarizing paragraphs to capture explicit information, and distinguishing between explicitly stated and inferred information. Encourage practice with passages that include both explicit and implicit information to strengthen detail retrieval skills.
14. According to the passage, what was the total duration and cost of the Sistine Chapel ceiling restoration project?
    Answer: The restoration required fourteen years of work and cost approximately $4.2 million to complete When you encounter reading comprehension questions asking for specific factual details, your success depends on careful attention to exact wording and precise information retrieval from the passage. This question tests your ability to locate and accurately report numerical data. The passage explicitly states two key facts: "The restoration process took fourteen years and cost approximately $4.2 million." This information directly supports answer choice A, which correctly identifies both the fourteen-year duration and the approximate $4.2 million cost. Let's examine why the other options are incorrect: Answer B provides inaccurate figures on both counts—it claims twelve years (not fourteen) and $3.8 million (not $4.2 million). This represents a common trap where test makers alter multiple details slightly. Answer C also contains dual errors: sixteen years instead of fourteen, and $4.5 million instead of $4.2 million. Again, this tests whether you're reading carefully or making assumptions. Answer D appears close but contains a critical error in precision. While it correctly states fourteen years and $4.2 million, it says "exactly $4.2 million" when the passage specifies "approximately $4.2 million." The word "exactly" changes the meaning and contradicts the passage's language. Remember that reading comprehension questions often include distractors with partially correct information or subtle word changes. Always verify that every detail in your chosen answer matches the passage exactly, paying special attention to qualifying words like "approximately," "nearly," or "about" versus "exactly" or "precisely."
15. How much more active does the glymphatic system become during sleep?
    Answer: The system becomes 60% more active during rest The passage clearly states that the glymphatic system 'becomes 60% more active during rest periods.' Choice A (90%) incorrectly uses a number from the REM sleep cycle information. Choices C (75%) and D (45%) provide percentages not mentioned in the passage.
16. Based on the information provided, what specific temperature and time requirements are mentioned for quantum computing operations?
    Answer: Processors require near-absolute-zero conditions (-273°C) and showed 200-second completion times for specific calculations When you encounter reading comprehension questions asking for specific details, you need to carefully distinguish between information that's directly stated versus information that might be implied or confused with other details in the passage. Looking at the passage, two key pieces of information are mentioned: qubits must be maintained at temperatures "approaching absolute zero (approximately -273°C)" and quantum computers completed specific calculations "in 200 seconds." However, these are separate facts about different aspects of quantum computing operations—temperature requirements for maintaining quantum states and processing time for particular calculations. Wait—I notice the question shows options A through D, but indicates the correct answer is E. Since option E isn't provided in the choices shown, there appears to be a formatting issue with this question. Looking at the given options: Choice A incorrectly suggests all quantum computers must complete calculations in 200 seconds. Choice B similarly links the temperature requirement directly to achieving 200-second processing times, when these are independent specifications. Choice C uses "exactly -273°C" (too precise) and "under 200 seconds" (not what the passage states). Choice D gives the wrong temperature (-270°C instead of approximately -273°C). Each wrong choice either misrepresents the precision of the measurements, incorrectly connects unrelated specifications, or provides inaccurate numbers. The passage presents the temperature and time as separate technical requirements, not as causally linked performance metrics. For reading comprehension questions about technical details, always distinguish between correlation and causation—just because two facts appear near each other doesn't mean they're directly related.
17. What is the maximum trunk diameter that redwood trees can develop?
    Answer: Redwood trunks can exceed 24 feet in diameter The passage clearly states that redwoods 'develop trunk diameters exceeding 24 feet.' Choice B (12 feet) incorrectly uses the bark thickness measurement. Choice C (380 feet) incorrectly uses the tree height. Choice D (450 feet) incorrectly uses the coastal range length.
18. At what elevation does Mount Everest's 'death zone' begin?
    Answer: The death zone starts at 26,000 feet elevation The passage explicitly states that 'The mountain's death zone begins at 26,000 feet.' Choice A (29,032 feet) incorrectly uses Mount Everest's total height. Choice B (24,000 feet) and Choice D (28,000 feet) provide elevations not mentioned in the passage.
19. Read the passage, then answer the question. In 1947, the United States announced the Marshall Plan, a program designed to help rebuild European economies after World War II. The plan was proposed by U.S. Secretary of State George C. Marshall in a speech at Harvard University on June 5, 1947. Marshall argued that economic recovery was necessary for political stability. Congress approved funding the following year, and the program officially began in 1948. Over the next several years, the United States provided financial aid and supplies to participating countries. The plan supported the rebuilding of infrastructure, the purchase of raw materials, and the modernization of industry. Sixteen European nations took part in the program. The aid was administered through an organization called the Organization for European Economic Cooperation (OEEC). By the early 1950s, many economies had improved, and trade levels increased. The Marshall Plan ended in 1952, but it remained influential as an example of large-scale international economic assistance. Question: According to the passage, where did George C. Marshall deliver the speech proposing the plan?
    Answer: Harvard University This question tests SSAT Upper Level reading skills: locating explicit details in a text. This skill involves identifying information directly stated in the passage, which requires careful reading and comprehension of explicit details. In this passage, details such as the location of Marshall's speech are clearly stated, helping readers understand the announcement of the Marshall Plan. The correct choice, B, is correct because it directly reflects the passage's information about the speech being delivered at Harvard University. A common distractor, A, is incorrect because it confuses the speech location with Congress's later approval in Washington, D.C. To help students, emphasize strategies such as highlighting key details while reading, summarizing paragraphs to capture explicit information, and distinguishing between explicitly stated and inferred information. Encourage practice with passages that include both explicit and implicit information to strengthen detail retrieval skills.
20. Read the passage, then answer the question. In 1962, marine biologist Rachel Carson published Silent Spring, a book that examined the environmental effects of certain pesticides. Carson had worked for the U.S. Fish and Wildlife Service and was known for earlier writings about the ocean. In Silent Spring, she described how chemicals such as DDT could accumulate in food chains and harm wildlife, including birds whose eggshells became dangerously thin. The book first appeared in serialized form in The New Yorker in the summer of 1962 and was released as a full volume later that year. Carson's writing combined scientific evidence with clear explanations intended for general readers. She also emphasized that the issue was not merely insects, but the broader consequences of widespread chemical use. Silent Spring drew intense public attention. Chemical companies criticized Carson's conclusions, while many scientists and citizens supported her call for stricter oversight. In 1963, Carson testified before a U.S. Senate subcommittee, urging careful evaluation of pesticide safety. Carson died on April 14, 1964, but her work continued to influence policy discussions. In the following years, the United States established the Environmental Protection Agency (EPA) in 1970. The EPA later banned most uses of DDT in the United States in 1972. Question: According to the passage, in what year was the Environmental Protection Agency established?
    Answer: 1970 This question tests SSAT Upper Level reading skills: locating explicit details in a text. This skill involves identifying information directly stated in the passage, which requires careful reading and comprehension of explicit details. In this passage, details such as the year the EPA was established are clearly stated, helping readers understand the long-term impact of Rachel Carson's work. The correct choice, D, is correct because it directly reflects the passage's information about the EPA being established in 1970. A common distractor, A, is incorrect because it refers to the publication year of Silent Spring in 1962, not the EPA's founding. To help students, emphasize strategies such as highlighting key details while reading, summarizing paragraphs to capture explicit information, and distinguishing between explicitly stated and inferred information. Encourage practice with passages that include both explicit and implicit information to strengthen detail retrieval skills.
