Q5FunctionO

The following text is adapted from Adib Khorram’s 2018 novel Darius the Great Is Not Okay. The narrator, Darius, is a teenager visiting family in Iran. He and his friend Sohrab are at the entrance of the ruins of the ancient city of Persepolis.

“The Gate of All Nations,” Sohrab said. He gestured to the lamassus [sculptures] and pillars surrounding us. “That’s the name in English.”

It wasn’t much of a gate anymore, since anyone of any nation could have easily stepped around it instead of walking through. But it was still amazing.

Behind the lamassu, more columns sprouted from the ground like ancient trees in a petrified forest, forty feet tall, spindly but still miraculously upright. Giant stone slabs formed the remains of what must once have been a breathtaking structure.

Which choice best describes the function of the underlined portion of the text?

  • A

    It presents an image to illustrate what one part of the ruins looks like.

  • B

    It emphasizes that the narrator already knows a lot about the city.

  • C

    It suggests that the narrator had expected to visit a forest.

  • D

    It indicates the specific time in the past when the buildings became ruins.

Q6PurposeO

Though John Crowley, author of Engine Summer, is perhaps not as well known as the most commercially successful American writers of the past fifty years, influential figures have championed his work, including the poet James Merrill and the literary critic Harold Bloom. In his afterword to Crowley’s book Little, Big, Bloom praises the novel’s adroit blend of what playwright Friedrich Schiller termed the naive and sentimental modes—while Schiller thought works could be classified as either naive (seeking to describe reality) or sentimental (seeking to develop ideas), Little, Big demonstrates that a work can be both.

Which choice best states the main purpose of the text?

Can field mustard plants grow on Mars? Can pea plants? You might think the answer to these questions is obviously no, but researchers in the Netherlands recently showed that the seeds of many common plant species can germinate in soil designed to simulate Martian conditions as long as water is supplied. In fact, some species actually did better in Martian soil than in Earth soil: 30 percent of field mustard seeds sprouted when planted in simulated Martian soil, compared with 4 percent that did when planted in soil from their home planet.

Which choice best states the main purpose of the text?

Q8Main IdeaX

In a study by Mika R. Moran, Daniel A. Rodriguez, and colleagues, residents of Panama City, Panama, and Fortaleza, Brazil, were surveyed about parks in their cities. Of the 318 respondents from Panama City, 53.5% indicated that they use the city's parks, and of the 938 respondents from Fortaleza, 35.7% indicated using city parks. Given that the percentage of Panama City respondents who reported having access to other desired amenities near parks was much lower than that reported by Fortaleza respondents, the difference in park use can't be explained by Panama City residents having more access to desired nonpark amenities near parks.

Which choice best describes the main idea of the text?

  • A

    Even though the study found that parks in Fortaleza are more likely to be close to other amenities than parks in Panama City are, Panama City has more amenities overall than Fortaleza does.

  • B

    The study’s findings suggest that an increase in the number of amenities near city parks would likely increase park use in Panama City but not in Fortaleza. 

  • C

    The study’s finding that a greater proportion of residents use parks in Panama City than in Fortaleza is partly due to the greater prevalence of parks in Panama City.

  • D

    Although the study found that a greater proportion of residents use parks in Panama City than in Fortaleza, that difference isn’t due to greater access to amenities near parks in Panama City.

In an extensive review of existing literature, Léna de Framond and team cataloged the prevalence of broken-wing display—a defensive behavior observed in Haematopus longirostris (pied oystercatcher) and many other species—throughout the Aves class. Documentation of the display in 285 species across 52 families suggests the behavior likely evolved independently multiple times, prompting the team to consider ecological and life-history characteristics with hypothesized associations to the behavior’s emergence, including traits related to reproduction investment and future reproduction potential. Based on their review of those traits, the team concluded that ______

Which choice most effectively uses data from the table to complete the conclusion?

  • A

    Capacity for multiple broods, number of parental incubators, and incubation duration are equally associated with the use of broken-wing display.

  • B

    Incubation duration and capacity for multiple broods are more strongly associated with the use of broken-wing display than the number of parental incubators is.

  • C

    Broken-wing display is most often observed in species with less opportunity to reproduce in a year due to longer incubation periods.

Q11Command of Evidence · If trueO

Puerto Rico is an island in the Caribbean Sea. Indigenous people there started raising guinea pigs about 1,700 years ago. Guinea pigs had originally been domesticated much earlier in both Colombia and Peru. So were guinea pigs brought to Puerto Rico from Colombia or from Peru? Ancient Caribbean trade routes connected Puerto Rico with Colombia but not with Peru. Therefore, guinea pigs in Puerto Rico probably came from Colombia and descended from Colombian guinea pigs.

Which finding, if true, would most directly weaken the underlined claim?

  • A

    Guinea pigs are common in ancient Puerto Rican art, especially in pottery.

  • B

    Ancient guinea pigs in Puerto Rico were genetically less similar to ancient guinea pigs in Colombia than to ancient guinea pigs in Peru.

  • C

    The guinea pig population of ancient Colombia was much larger than the guinea pig population of ancient Peru.

Q13Command of Evidence · If trueX

Almost all works of fiction contain references to the progression of time, including the time of day when events in a story take place. In a 2020 study, Allen Kim, Charuta Pethe, and Steven Skiena claim that an observable pattern in such references reflects a shift in human behavior prompted by the spread of electric lighting in the late nineteenth century. The researchers drew this conclusion from an analysis of more than 50,000 novels spanning many centuries and cultures, using software to recognize and tally both specific time references—that is, clock phrases, such as 7 a.m. or 2:30 p.m.—and implied ones, such as mentions of meals typically associated with a particular time of day.

Which finding from the study, if true, would most directly support the researchers' conclusion?

  • A

    Novels published after the year 1800 include the clock phrase 10 a.m. less often than novels published before the year 1800 do.

  • B

    Among novels published in the nineteenth century, implied time references become steadily more common than clock phrases as publication dates approach 1900.

  • C

    The time references of noon (12 p.m.) and midnight (12 a.m.) are used with roughly the same frequency in the novels.

  • D

    Novels published after 1880 contain significantly more references to activities occurring after 10 p.m. than do novels from earlier periods.

As exemplified by Temiar songs about landforms and landmarks and Lakota songs about gathering mouse beans, ecological information can be transmitted in Indigenous songs, and in some instances is maintained only in this way. Kwaxsistalla Wathl’thla, a song keeper for the Kwakwaka’wakw people in Canada, collaborated with ethnobiologist Dana Lepofsky et al., sharing songs referencing terraced intertidal clam gardens the people implemented in the past to foster healthy development of a dietary staple. Drawing on archaeological evidence as well, Lepofsky et al. determined that the prevalence of the practice described in the songs corresponded with growth in clam size and abundance despite increased harvesting pressure—a finding that demonstrates that _____

Which choice most logically completes the text?

  • A

    representation of practical applications of ecological knowledge is the defining characteristic of the music of certain Indigenous peoples.

  • B

    the Kwakwaka’wakw people likely would not have detailed their creation of clam gardens in songs if their efforts had not produced significantly larger clams.

    the clams harvested from intertidal terraces by Kwakwaka’wakw people in the past likely were a different species than the clams found in those areas today.

Q4FunctionX

Vertical gene transfer involves the transmission of genetic material from a parent to offspring; horizontal gene transfer, on the other hand, involves the exchange of genetic material between organisms not in a parent-offspring relationship. While horizontal gene transfer is common among prokaryotes—single-celled organisms, such as the bacteria Brevundimonas diminuta and Massilia timonae—it has rarely been observed among eukaryotes (multicellular organisms). However, new studies suggest that horizontal gene transfer is more common in eukaryotes than originally thought.

Q5PurposeX

During Rome’s republican period, which ended in the first century BCE, libraries were predominantly owned by wealthy individuals who tightly controlled access to their book collections. The first public library became available in Rome in 28 BCE and was soon followed by one commissioned by Emperor Augustus. As modern scholar Fabio Fernandes notes, however, these two traditions aren’t as distinct as they seem, as both the emperor and the private library owners viewed their libraries as extensions of their personal patronage, just on vastly differing scales.

Which choice best states the main purpose of the text?

  • A

    To call into question the notion that private Roman libraries disappeared during the first century BCE

  • B

    To contend that early imperial leaders in Rome wielded too much influence over libraries

  • C

My spirit swoons, and all my senses cry

For Ocean’s breast and covering of the sky.

Rock me to sleep, ye waves, and outward bound,

Just let me drift far out from toil and care,

Where lapping of the waves shall be the sound,

Which mingled with the winds that gently bear

Me on between a peaceful sea and sky,

To make my soothing slumberous lullaby.

Q7Cross-TextO

Text 1

Scholarship today overrepresents experimentally fragmented narrative structures, such as that of Flann O’Brien’s At Swim-Two-Birds, beyond the degree to which they actually influenced fiction in Britain and Ireland during the modernist period (roughly 1900–1945). Meanwhile, Elizabeth Bowen’s The Last September, whose coherent, linear narrative structure recalls the fiction of previous centuries, attracts woefully little attention from scholars of modernism.


Text 2

Distant reading, or computer-assisted quantitative analysis of massive collections of digitized texts, can reveal stylistic elements that have heretofore escaped notice, despite being shared by numerous texts from the modernist period. For too long, scholars have focused on narrative fragmentation versus coherence, inhibiting inquiry into other points of stylistic correspondence among works that would enrich our understanding of the modernist canon.


Based on the texts, both the author of Text 1 and the author of Text 2 would most likely agree with which statement about scholarship on works from the modernist period in Britain and Ireland?

  • A

    It must widen its focus to include aspects of modernist fiction beyond style, a productive but overrepresented site of inquiry.

  • B

    Without a major shift in focus, the vision that it presents of fiction written in the period will continue to be unnecessarily limited.

  • C

    Instead of engaging in unproductive debates, it should work to rehabilitate the reputations of neglected modernist works.

  • D

    Its primary methods for analyzing fiction written in the period are growing obsolete as computer technology advances.

Q8Direct ComprehensionX

Many artists associated with hyperpop, a movement in electronic music that emerged in the 2010s, conform to the model perfected by the American duo 100 gecs: bold synthesizer arrangements, propulsive beats, and electronically manipulated vocals. Yet the movement is hardly uniform: Swedish recording artist Namasenda incorporates hip-hop rhythms into the hyperpop sound, for example. Such stylistic diversity is encouraged in part by the music-streaming app Spotify, whose curated playlist of hyperpop songs balances cohesion with variety.

Which statement about Namasenda is best supported by the text?

  • A

    While some of her recordings conform to the model perfected by 100 gecs, others reject it outright.

  • B

    Her music diverges from the typical hyperpop sound but doesn’t abandon it.

  • C

    She developed her unique sound without being influenced by other artists on Spotify’s hyperpop playlist.

  • D

    Her inclusion on Spotify’s hyperpop playlist inspired established artists to embrace stylistic experimentation.

Q10Main IdeaX

Eighteenth-century economist Adam Smith is famed for his metaphor of the invisible hand, which he putatively used to illustrate a robust model of how individuals produce aggregate benefits by pursuing their own economic interests. Note “putatively”: as Gavin Kennedy has shown, Smith deploys this metaphor only once in his economic writings—to make a narrow point about the then-dominant economic theory of mercantilism—and it was largely ignored until some twentieth-century economists eager to secure an intellectual pedigree for their views elevated it to a fully-fledged paradigm.

Which choice best states the main idea of the text?

  • A

    Some twentieth-century economists gave Smith’s metaphor of the invisible hand a significance it does not have in Smith’s work, but it is nevertheless a useful model of how individuals produce aggregate benefits by pursuing their own economic interests.  

  • B

    Smith’s metaphor of the invisible hand has been interpreted as a model of how individuals acting in their own interest produce aggregate benefits, but it was intended as a subtle critique of the economic theory of mercantilism.

  • C

    The reputation of Smith’s metaphor of the invisible hand is not due to the importance of the metaphor in Smith’s work but rather to the promotion of the metaphor by some later economists for their own ends.

  • D

    Although Smith is famed for his metaphor of the invisible hand, the metaphor was largely ignored until economists in the twentieth century came to realize that the metaphor was a robust model that anticipated their own views.

Q12Command of Evidence · If true어려움X

Early Earth is thought to have been characterized by a stagnant lid tectonic regime, in which the upper lithosphere (the outer rocky layer) was essentially immobile and there was no interaction between the lithosphere and the underlying mantle. Researchers investigated the timing of the transition from a stagnant lid regime to a tectonic plate regime, in which the lithosphere is fractured into dynamic plates that in turn allow lithospheric and mantle material to mix. Examining chemical data from lithospheric and mantle-derived rocks ranging from 285 million to 3.8 billion years old, the researchers dated the transition to 3.2 billion years ago.

Which finding, if true, would most directly support the researchers’ conclusion?

  • A

    Mantle-derived rocks older than 3.2 billion years show significantly more compositional diversity than lithospheric rocks older than 3.2 billion years do.

  • B

    There is a positive correlation between the age of lithospheric rocks and their chemical similarity to mantle-derived rocks, and that correlation increases significantly in strength at around 3.2 billion years old.

  • C

    Mantle-derived rocks younger than 3.2 billion years contain some material that is not found in older mantle-derived rocks but is found in older and contemporaneous lithospheric rocks.

  • D

    Among rocks known to be older than 3.2 billion years, significantly more are mantle-derived than lithospheric, but this difference decreases in rocks younger than 3.2 billion years.

Scholars are increasingly exploring the communication and preservation of ecological knowledge through Indigenous songs (e.g., Temiar songs about landforms and landmarks and those of the Tlingit people about wildlife encounters). In one study, ethnobiologist Dana Lepofsky et al. received insight from Kwaxsistalla Wathl'thla, a song keeper for the Kwakwaka’wakw people in Canada, into songs referencing the people’s use of terraced gardens in intertidal zones along the Pacific Northwest coast for the cultivation of clams for consumption.

    there is greater corroboration in the archaeological record of ecological practices described in Kwakwaka’wakw songs than of those described in Temiar and Tlingit songs.

Q15Inference · SyllogismX

For its 1974 work Instant Mural, the Chicano art collective Asco taped members Patssi Valdez and Humberto Sandoval to an outdoor wall in East Los Angeles. The work is manifestly a commentary on constraint, but many critics focus on Valdez and the social constraints women faced at the time, which is understandable but leaves the presence of Valdez’s male collaborator Sandoval unexplained. We should instead consider that in 1974, the art establishment’s recognition of Chicano artists was (and had long been) restricted to sociohistorical muralists, leaving nonmuralist Chicano artists—like Asco’s members—struggling to even exhibit their work; attending to this context opens an interpretation that accounts for all the evidence, allowing us to conclude that ______

Which choice most logically completes the text?

  • A

    while Valdez’s presence in Instant Mural represents the social constraints placed on women at the time, Sandoval’s presence represents Chicano muralists’ frustration at their lack of recognition by the art establishment.

  • B

    the main subject of Instant Mural is female Chicano artists’ experience of being doubly constrained by gender-role expectations and the marginalization of certain types of art.

  • C

    Instant Mural is best understood not as a critique of the social constraints placed on women but rather as a critique of sociohistorical muralists’ depictions of Chicano culture.

  • D

    Instant Mural is a reflection on the constraining aesthetic expectations placed on Chicano artists in general rather than on the social constraints placed on women specifically.
