Passage
Honeybees are essential to global agriculture, pollinating roughly one-third of all food crops consumed by humans, including apples, almonds, blueberries, and cucumbers. A single colony can contain up to 60,000 bees during peak summer months. Worker bees, all of which are female, perform specialized roles including foraging, nursing larvae, and defending the hive. The queen bee, whose sole function is reproduction, can lay up to 2,000 eggs per day during peak season.
According to the passage, which of the following is a role performed by worker bees?
2Easy
Passage
The Great Wall of China, one of the most remarkable architectural achievements in human history, was not built all at once. Construction began as early as the 7th century BCE, and different sections were built by different Chinese states and dynasties over more than two millennia. The wall as most tourists see it today was largely constructed during the Ming Dynasty (1368–1644 CE). At its greatest extent, the wall stretched over 13,000 miles, incorporating watchtowers, garrison stations, and signaling capabilities using smoke and fire.
According to the passage, which dynasty was primarily responsible for constructing the Great Wall as it appears to most tourists today?
3Easy
Passage
The human brain contains approximately 86 billion neurons, each capable of forming thousands of connections with other neurons through structures called synapses. The brain consumes roughly 20% of the body's total energy despite accounting for only about 2% of body weight. Different regions of the brain are associated with different functions: the prefrontal cortex handles reasoning and planning, the hippocampus is crucial for memory formation, and the amygdala processes emotional responses, particularly fear.
Based on the passage, which part of the brain is primarily associated with memory formation?
4Easy
Passage
The Renaissance, which flourished primarily in Italy between the 14th and 17th centuries, represented a profound cultural rebirth after the Middle Ages. It was characterized by a renewed interest in classical Greek and Roman texts, a focus on humanism (the idea that humans, not divine forces, are the center of intellectual life), and remarkable advances in art, literature, architecture, and science. Key figures of the Renaissance include Leonardo da Vinci, Michelangelo, Galileo Galilei, and Niccolò Machiavelli.
According to the passage, which of the following best describes humanism as defined in the passage?
5Easy
Passage
Photosynthesis is the process by which green plants, algae, and some bacteria convert light energy — typically from the sun — into chemical energy stored in glucose. The process takes place primarily in the chloroplasts, organelles found in plant cells that contain a green pigment called chlorophyll. Chlorophyll absorbs mainly red and blue light wavelengths while reflecting green light, which is why plants appear green to the human eye. The overall equation for photosynthesis is: 6CO₂ + 6H₂O + light energy → C₆H₁₂O₆ + 6O₂.
According to the passage, why do most plants appear green?

Passage
The Harlem Renaissance, spanning roughly from the 1920s to the mid-1930s, was an intellectual and cultural explosion centered in the Harlem neighborhood of New York City. African American writers, artists, musicians, and intellectuals produced works that challenged racial stereotypes, asserted Black identity, and engaged with the political demands of the time. Langston Hughes's poetry celebrated ordinary Black life with warmth and dignity; Zora Neale Hurston's anthropological fiction rooted itself in Southern Black folk traditions; Aaron Douglas's visual art fused African iconography with modernist geometric forms. Though these figures disagreed about the best strategies for racial advancement — Hughes was more politically radical, while Alain Locke favored cultivating a "talented tenth" of Black intellectuals — they shared a conviction that artistic and cultural expression was inseparable from the struggle for civil rights.
Which of the following details from the passage best supports the claim that Harlem Renaissance figures disagreed about strategy even while sharing a common goal?
7Medium
Passage
Recent studies of sleep deprivation have revealed effects far more wide-ranging than simple fatigue. After just one night of fewer than six hours of sleep, subjects show measurable declines in working memory, reaction time, and emotional regulation. The immune system is also compromised: sleep-deprived individuals produce fewer natural killer cells, which play a key role in fighting infections and surveilling the body for cancerous cells. Perhaps most surprisingly, chronic sleep deprivation — defined in most research as consistently getting fewer than seven hours per night — has been linked to accelerated cognitive decline and a significantly elevated risk of Alzheimer's disease, potentially because sleep is when the brain flushes out amyloid proteins that, when accumulated, are associated with the disease.
According to the passage, what is one proposed mechanism by which chronic sleep deprivation may increase the risk of Alzheimer's disease?

Passage
The construction of the transcontinental railroad, completed in 1869, fundamentally transformed the United States. Before its completion, travel from New York to California took several months by wagon or ship. The railroad reduced this journey to about a week. The project was built by two companies working toward each other: the Union Pacific, which laid tracks westward from Omaha, Nebraska, and the Central Pacific, which built eastward from Sacramento, California. The workforce was strikingly diverse: Union Pacific relied heavily on Irish immigrants and Civil War veterans, while Central Pacific employed approximately 10,000 to 20,000 Chinese laborers who performed some of the most dangerous work, including blasting through the Sierra Nevada mountains. The two lines met at Promontory Summit, Utah, on May 10, 1869, an event celebrated with the ceremonial driving of a golden spike.
Which detail from the passage best illustrates the hardships faced by workers building the transcontinental railroad?
9Hard
Passage
The philosopher Hannah Arendt, in her 1963 report on the trial of Nazi war criminal Adolf Eichmann, introduced one of the twentieth century's most controversial and enduring concepts: the "banality of evil." Arendt observed that Eichmann, who had coordinated the logistics of deporting millions of Jews to extermination camps, was not a monster or a fanatic. He was, she argued, a strikingly ordinary bureaucrat — neither sadistic nor ideologically driven by virulent anti-Semitism, but rather disturbingly thoughtless. He followed orders, used bureaucratic language, and seemed incapable of genuine moral reflection. The evil he facilitated was not the product of demonic will but of the absence of thought — of a failure to ask what he was actually doing and to whom. Critics, most notably political philosopher Gideon Hausner (who prosecuted Eichmann) and historian Deborah Lipstadt, have disputed Arendt's portrait, arguing that she underestimated Eichmann's ideological commitment and that her thesis, however philosophically provocative, risks diminishing the moral responsibility of perpetrators.
Which detail from the passage most directly supports Arendt's claim that Eichmann's evil was rooted in thoughtlessness rather than ideology?
10Hard
Passage
In ecology, the concept of a "keystone species" refers to an organism whose impact on its ecosystem is disproportionately large relative to its abundance. The removal of a keystone species triggers a cascade of changes — often called a "trophic cascade" — that restructures the entire ecological community. The reintroduction of gray wolves into Yellowstone National Park in 1995 is a frequently cited illustration. Before wolves returned, elk populations had grown unchecked and heavily grazed river banks, preventing vegetation recovery and leading to soil erosion. After wolf reintroduction, elk behavior changed: they avoided lingering near rivers, allowing willows, aspens, and cottonwoods to regenerate. This vegetation stabilized riverbanks, altered water flow, and created habitat for beavers, otters, songbirds, and fish. The wolves, through a combination of direct predation and induced behavioral change in elk, had altered the rivers themselves — a phenomenon researchers termed a "behaviorally mediated trophic cascade."
According to the passage, which specific detail most directly demonstrates that the wolves' impact on Yellowstone was mediated through elk behavior rather than through direct predation alone?
