Explanation
This question tests ISEE Upper Level reading comprehension skills, specifically the ability to locate and understand explicit information stated in a passage. Explicit information retrieval involves identifying details directly presented in the text without drawing inferences. It's essential for understanding the literal content of a text. In this passage, details about the Apollo 11 mission crew roles are clearly stated, providing a straightforward basis for retrieval questions. The correct answer is A because it is a direct restatement of information found in the passage, specifically "Armstrong and Aldrin traveled to the lunar surface in the Lunar Module, while Collins remained in lunar orbit in the Command Module." Common distractors, such as Collins walking on the Moon or serving as mission director, fail because they contradict the explicit statement about his role. To develop these skills, students should practice distinguishing between what is explicitly stated and what requires inference, focusing on identifying keywords and phrases that signal explicit information. Encourage close reading and annotation to track direct statements about individual roles and responsibilities.
Read the passage, then answer the question.
Volcanoes form when molten rock, called magma, rises from Earth’s interior and reaches the surface as lava. The passage states that magma contains dissolved gases, and as pressure decreases near the surface, these gases can expand rapidly. This expansion can drive explosive eruptions, especially when magma is thick and traps gas. By contrast, thinner, more fluid lava can flow more easily and may produce less explosive eruptions.
The passage explicitly notes that volcanoes are common near tectonic plate boundaries. At convergent boundaries, one plate can sink beneath another, producing magma that feeds volcanic arcs. At divergent boundaries, plates pull apart, and magma rises to fill the gap, creating volcanic activity along mid-ocean ridges. Hot spots, such as the one associated with Hawaii, can also create volcanoes away from plate boundaries.
Scientists monitor volcanoes using tools that measure earthquakes, ground deformation, and gas emissions. The passage states that increased seismic activity can indicate magma movement underground. Monitoring cannot prevent eruptions, yet it can improve warnings and reduce risk for nearby communities. Understanding eruption styles helps planners prepare for hazards such as ash fall and lava flows.
Question: What does the passage state about dissolved gases in magma?
They exist only in underwater volcanoes and are absent in land volcanoes.
They can expand as pressure decreases and can drive explosive eruptions.
They turn magma into solid rock instantly when it approaches the surface.
They prevent all eruptions by cooling magma before it reaches the surface.

Read the passage, then answer the question.
In Jane Austen’s Pride and Prejudice, Elizabeth Bennet is introduced as intelligent, observant, and willing to challenge social expectations. The novel is set in rural England, where marriage and property laws strongly influence family decisions. The passage states that the Bennet family estate, Longbourn, is entailed away from the daughters, meaning it will pass to a male relative. Because of this entailment, Mrs. Bennet is anxious to see her daughters married advantageously.
Mr. Darcy first appears as wealthy and reserved, and Elizabeth initially judges him as proud. Mr. Bingley, Darcy’s friend, is described as sociable and quickly interested in Jane Bennet. The passage explicitly notes that Darcy later writes a letter to Elizabeth explaining his actions, including his role in separating Bingley and Jane. This letter becomes a crucial moment in Elizabeth’s understanding of Darcy’s character.
As the story progresses, Elizabeth learns about George Wickham’s dishonesty and about Darcy’s efforts to address Lydia Bennet’s scandal. The passage states that Darcy arranges a marriage between Lydia and Wickham to reduce the family’s public disgrace. By the novel’s conclusion, Elizabeth and Darcy marry, and the passage presents their relationship as based on mutual respect rather than superficial attraction. Austen’s narrative voice is described as ironic, especially when discussing class and manners.
Question: What information is directly provided about the entailment of Longbourn?
Longbourn is inherited equally by all daughters under a modern legal code.
Longbourn is sold to pay the Bennet family’s gambling debts in London.
Longbourn will pass to a male relative rather than to the Bennet daughters.
Longbourn is promised to Mr. Darcy as part of a secret engagement contract.

Read the passage, then answer the question.
In 1935, the Social Security Act was signed into law in the United States as part of the New Deal era. The passage states that the act created a federal system of old-age benefits funded through payroll taxes. It also established unemployment insurance, which provided temporary payments to eligible workers who lost jobs. The law emerged during the Great Depression, when high unemployment and financial insecurity affected millions of families.
The passage explicitly notes that Social Security was designed as a contributory system, meaning workers and employers paid into it over time. Benefits were not described as automatic gifts; instead, they were connected to a history of contributions. Over the decades, the program expanded, and later amendments added benefits for survivors and people with disabilities. Administration of the program required recordkeeping to track earnings and determine eligibility.
The passage states that Social Security did not eliminate poverty entirely, yet it created a nationwide framework for income support in old age. It also notes that debates about funding and long-term sustainability have continued. Nevertheless, the act is presented as a major policy change in American government. Its creation marked a significant expansion of federal responsibility for economic security.
Question: What does the passage state about how old-age benefits were funded under the Social Security Act?
They were funded only by profits from federal land sales in western states.
They were funded by a one-time inheritance tax imposed on wealthy families.
They were funded entirely by voluntary donations collected by local charities.
They were funded through payroll taxes paid by workers and employers over time.

Read the passage, then answer the question.
The Great Barrier Reef is a vast marine ecosystem located off the northeastern coast of Australia. The passage states that it is composed of thousands of individual reefs and hundreds of islands, and it stretches for over 2,000 kilometers. Reef-building corals are living animals that secrete calcium carbonate skeletons, which accumulate over time to form complex structures. These structures provide habitat for many species of fish, mollusks, and other marine organisms.
The passage explicitly notes that corals rely on symbiotic algae called zooxanthellae, which live in coral tissues and help provide energy through photosynthesis. When corals experience stress, such as unusually warm water, they can expel these algae, causing coral bleaching. Bleached corals are not necessarily dead, yet they are more vulnerable if stressful conditions persist. The passage states that scientists monitor reef health using surveys and satellite data.
The reef supports tourism and fishing, and it is also valued for biodiversity. The passage notes that conservation efforts include reducing water pollution and managing fishing practices. Because the reef is large and complex, protection requires cooperation among governments, researchers, and local communities. The passage presents the reef as both ecologically important and economically significant.
Question: What does the passage state about zooxanthellae in reef-building corals?
They are predators that eat coral polyps and cause reefs to collapse quickly.
They are deep-sea bacteria found only in waters below 5,000 meters.
They are mineral crystals that form the coral skeleton without any living process.
They are symbiotic algae that live in coral tissues and help provide energy.

Read the passage, then answer the question.
In Shakespeare’s tragedy Macbeth, the title character begins as a respected Scottish nobleman and a successful military leader. Early in the play, three witches predict that Macbeth will become king, and this prediction becomes a turning point in his thinking. Macbeth writes in a letter to his wife, Lady Macbeth, describing the prophecy and its implications. Lady Macbeth immediately urges him to seize the crown through decisive action rather than waiting for events to unfold.
King Duncan visits Macbeth’s castle, and Macbeth and Lady Macbeth plan Duncan’s murder. The passage states that Macbeth kills Duncan while Duncan is a guest in his home, an act that violates the social expectations of hospitality. After the murder, Macbeth experiences intense guilt and fear, and he begins to suspect others will discover his crime. To secure his power, he orders additional killings, including the murder of his former friend Banquo.
As Macbeth’s rule continues, Scotland suffers under his tyranny, and the play describes the nation as troubled and fearful. Lady Macbeth, who earlier appeared confident, later sleepwalks and speaks fragments of her guilt. Macbeth, increasingly isolated, relies on further prophecies, yet these predictions mislead him by giving a false sense of security. The play ends when Macbeth is defeated in battle and Malcolm, Duncan’s son, is declared king.
Question: What does the passage state about King Duncan’s death?
Duncan was poisoned by Lady Macbeth during a banquet at court.
Duncan survived the attack and later exiled Macbeth from Scotland.
Duncan was killed by Macbeth while visiting Macbeth’s castle as a guest.
Duncan died during a public rebellion led by Macbeth’s soldiers.

Read the passage, then answer the question.
In 1928, Alexander Fleming, a bacteriologist working in London, observed an unusual result while studying bacteria in petri dishes. One dish had been contaminated by a mold, and around the mold the bacteria failed to grow. Fleming identified the mold as belonging to the genus Penicillium and concluded that it released a substance that killed or inhibited bacteria. He named this substance penicillin, and he published his findings in 1929.
Although Fleming had identified penicillin’s antibacterial effect, he did not have the equipment to purify it into a stable medicine. In the late 1930s and early 1940s, a team at the University of Oxford, including Howard Florey and Ernst Chain, developed methods to isolate and concentrate penicillin. Their work required careful chemical processing and repeated testing to confirm that the substance could treat infections in living organisms. During World War II, large-scale production expanded, because governments and manufacturers recognized its value for treating wounded soldiers.
Penicillin represented a major shift in medicine because it provided an effective treatment for many bacterial diseases that had previously been difficult to manage. The passage states that penicillin does not treat viral infections, because viruses and bacteria are biologically different. It also states that widespread antibiotic use can contribute to antibiotic resistance, which occurs when some bacteria survive and adapt. For this reason, physicians later emphasized using antibiotics appropriately rather than indiscriminately.
Question: What information is directly provided about Fleming’s initial observation?
He noticed bacteria growing faster near a mold because the mold provided nutrients.
He proved that penicillin was effective against viruses as well as bacteria.
He discovered that a moldy dish showed bacteria failing to grow around the mold.
He immediately purified penicillin into a stable drug using advanced laboratory equipment.

Read the passage, then answer the question.
The Harlem Renaissance was a cultural movement that flourished in the 1920s and early 1930s, centered in the Harlem neighborhood of New York City. The passage states that it involved literature, music, visual art, and intellectual debate, and it highlighted the creativity of African American communities. Writers such as Langston Hughes produced poems that drew on everyday speech and jazz rhythms. Zora Neale Hurston collected folklore and wrote fiction that emphasized regional voices and traditions.
The passage explicitly notes that jazz and blues were prominent musical forms during this period, and clubs in Harlem attracted diverse audiences. Artists and thinkers discussed racial identity, political rights, and cultural pride, often in magazines and public lectures. The movement was supported in part by publishers and patrons who funded artistic projects. However, the passage states that economic hardship during the Great Depression reduced opportunities for many artists.
The Harlem Renaissance influenced later generations by expanding the visibility of African American art in national culture. It also encouraged new approaches to portraying Black life with complexity and dignity. The passage presents the movement as both an artistic flowering and a social conversation. Its legacy is described as enduring in American literature and music.
Question: Which of the following is explicitly mentioned in the passage?
The movement began in the 1850s and focused mainly on industrial technology.
The movement was centered in Harlem, a neighborhood of New York City.
The movement ended because a single law banned jazz clubs throughout the nation.
The movement was directed by a government agency that assigned artists their themes.

The International Space Station (ISS) is a large research laboratory that orbits Earth and supports long-term human habitation in space. The passage states that the first module, Zarya, was launched in 1998, marking the beginning of on-orbit assembly. The station was built through cooperation among multiple space agencies, including NASA, Roscosmos, the European Space Agency, JAXA, and the Canadian Space Agency. Astronauts and cosmonauts have conducted experiments on the ISS in biology, physics, and materials science.
The ISS travels around Earth at high speed and completes multiple orbits each day. Because it is in microgravity, researchers can study phenomena that behave differently than they do on Earth. The passage explicitly notes that the ISS has been continuously occupied by humans since 2000. Supplies and crew members reach the station through spacecraft launches, and visiting vehicles dock to deliver cargo and equipment.
The station also serves as a testing ground for technologies needed for future missions. For example, the passage states that the ISS has supported studies on how long-term spaceflight affects the human body, including bone density and muscle loss. These findings are used to plan safer journeys for astronauts. The ISS is therefore presented as both a scientific platform and a symbol of international collaboration.
Question: Which of the following is explicitly mentioned in the passage?
The ISS has been continuously occupied by humans since the year 2000.
The ISS ended all research operations after its first decade of service.
The ISS orbits the Moon and serves primarily as a lunar communications relay.
The ISS was assembled entirely on Earth before being launched as a single structure.

Read the passage, then answer the question.
The process of photosynthesis allows plants and certain algae to convert light energy into chemical energy stored in sugars. The passage states that photosynthesis occurs primarily in chloroplasts, which contain the green pigment chlorophyll. In the first stage, called the light-dependent reactions, chlorophyll absorbs sunlight and helps split water molecules. This splitting releases oxygen gas as a byproduct, and it also generates energy-rich molecules used in the next stage.
In the second stage, commonly called the Calvin cycle, carbon dioxide from the air is incorporated into organic molecules. The passage explicitly notes that this stage does not require light directly, although it depends on energy produced earlier. Through a series of reactions, plants produce glucose and related sugars that can be used for growth and storage. Because photosynthesis removes carbon dioxide and releases oxygen, it influences Earth’s atmospheric composition.
The passage also states that photosynthesis is limited by factors such as light intensity, carbon dioxide concentration, and temperature. If one factor is insufficient, the overall rate can slow even when other conditions are favorable. Scientists measure photosynthetic rate to understand plant productivity in agriculture and ecosystems. This information is used to improve crop yields and manage environmental resources.
Question: Which statement is directly supported by the passage?
Oxygen is released when water molecules are split during light-dependent reactions.
The Calvin cycle requires bright sunlight because it occurs only at midday.
Photosynthesis takes place mainly in mitochondria, where respiration occurs.
Photosynthesis increases atmospheric carbon dioxide by producing it as a waste gas.
