Many archaeologists assume that large-scale engineering projects in ancient societies required an elite class to plan and direct the necessary labor. However, recent discoveries, such as the excavation of an ancient canal near the Gulf Coast of Alabama, have complicated this picture. Using radiocarbon dating, a team of researchers concluded that the 1.39kilometer-long canal was most likely constructed between 576 and 650 CE by an Indigenous society that was relatively free of social classes.

Michelene Pesantubbee, a historian and citizen of the Choctaw Nation, has identified a dilemma inherent to research on the status of women in her tribe during the 1600s and 1700s: the primary sources from that era, travel narratives and other accounts by male European colonizers, underestimate the degree of power conferred on Choctaw women by their traditional roles in political, civic, and ceremonial life. Pesantubbee argues that the Choctaw oral tradition and findings from archaeological sites in the tribe’s homeland supplement the written record by providing crucial insights into those roles.

Musician Joni Mitchell, who is also a painter, uses images she creates for her album covers to emphasize ideas expressed in her music. For the cover of her album Turbulent Indigo (1994), Mitchell painted a striking self-portrait that closely resembles Vincent van Gogh’s Self-Portrait with Bandaged Ear (1889). The image calls attention to the album’s title song, in which Mitchell sings about the legacy of the postimpressionist painter. In that song, Mitchell also hints that she feels a strong artistic connection to Van Gogh—an idea that is reinforced by her imagery on the cover.

Part of the Atacama Desert in Peru has surprisingly rich plant life despite receiving almost no rainfall. Moisture from winter fog sustains plants once they’re growing, but the soil’s tough crust makes it hard for seeds to germinate in the first place. Local birds that dig nests in the ground seem to be of help: they churn the soil, exposing buried seeds to moisture and nutrients. Indeed, in 2016 Cristina Rengifo Faiffer found that mounds of soil dug up by birds were far more fertile and supported more seedlings than soil in undisturbed areas.

By combining Indigenous and classical music, Cree composer and cellist Cris Derksen creates works that reflect the diverse cultural landscape of Canada. For her album Orchestral Powwow, Derksen composed new songs in the style of traditional powwow music that were accompanied by classical arrangements played by an orchestra. But where an orchestra would normally follow the directions of a conductor, the musicians on Orchestral Powwow are led by the beat of a powwow drum.

The following text is adapted from Paul Laurence Dunbar’s 1902 novel The Sport of the Gods. Joe and some of his family members have recently moved to New York City.

[Joe] was wild with enthusiasm and with a desire to be a part of all that the metropolis meant. In the evening he saw the young fellows passing by dressed in their spruce clothes, and he wondered with a sort of envy where they could be going. Back home there had been no place much worth going to, except church and one or two people’s houses.

Early in the Great Migration of 1910–1970, which involved the mass migration of Black people from the southern to the northern United States, political activist and Chicago Defender writer Fannie Barrier Williams was instrumental in helping other Black women establish themselves in the North. Many women hoped for better employment opportunities in the North because, in the South, they faced much competition for domestic employment and men tended to get agricultural work. To aid with this transition, Barrier Williams helped secure job placement in the North for many women before they even began their journey.

Archeological excavation of Market Street Chinatown, a nineteenth-century Chinese American community in San Jose, California, provided the first evidence that Asian food products were imported to the United States in the 1800s: bones from a freshwater fish species native to Southeast Asia. Jinshanzhuang—Hong Kong–based import/export firms—likely coordinated the fish’s transport from Chinese-operated fisheries in Vietnam and Malaysia to North American markets. This route reveals the (often overlooked) multinational dimensions of the trade networks linking Chinese diaspora communities.

Using NASA’s powerful James Webb Space Telescope (JWST), Mercedes López-Morales and colleagues measured the wavelengths of light traveling through the atmosphere of WASP-39b, an exoplanet, or planet outside our solar system. Different molecules absorb different wavelengths of light, and the wavelength measurements showed the presence of carbon dioxide (CO₂) in WASP-39b’s atmosphere. This finding not only offers the first decisive evidence of CO₂ in the atmosphere of an exoplanet but also illustrates the potential for future scientific breakthroughs held by the JWST.

Which choice best describes the overall structure of the text?

Correct Answer: B

Rationale

Choice B is the best answer. The text begins by describing how the researchers used the JWST to detect CO₂ in WASP39b’s atmosphere. Then the text discusses the significance of this finding, both as the first evidence of CO₂ in an exoplanet’s atmosphere and as an illustration of the JWST’s potential for making new discoveries in general.

Choice A is incorrect. The text doesn’t compare two different methods, but rather focuses on one study that used the JWST. Choice C is incorrect. The text doesn’t present a hypothesis, but rather reports on the findings of a study. Choice D

is incorrect. The text doesn’t mention any scientists challenging the conclusion reached by López-Morales and colleagues.

The following text is from Joseph Conrad’s 1907 novel The Secret Agent: A Simple Tale. Mr. Verloc is navigating the London streets on his way to a meeting.

Before reaching Knightsbridge, Mr. Verloc took a turn to the left out of the busy main thoroughfare, uproarious with the traffic of swaying omnibuses and trotting vans, in the almost silent, swift flow of hansoms [horse-drawn carriages]. Under his hat, worn with a slight backward tilt, his hair had been carefully brushed into respectful sleekness; for his business was with an Embassy. And Mr. Verloc, steady like a rock—a soft kind of rock—marched now along a street which could with every propriety be described as private.

In 1973, poet Miguel Algarín started inviting other writers who, like him, were Nuyorican—a term for New Yorkers of

Puerto Rican heritage—to gather in his apartment to present their work. The gatherings were so well attended that Algarín soon had to rent space in a cafe to accommodate them. Thus, the Nuyorican Poets Cafe was born. Moving to a permanent location in 1981, the Nuyorican Poets Cafe expanded its original scope beyond the written word, hosting art exhibitions and musical performances as well. Half a century since its inception, it continues to foster emerging Nuyorican talent.

The following text is from the 1923 poem “Black Finger” by Angelina Weld Grimké, a Black American writer. A cypress is a type of evergreen tree.

I have just seen a most beautiful thing,

Slim and still,

 Against a gold, gold sky,

 A straight black cypress,

Sensitive,

Exquisite,

A black finger

Pointing upwards.

Why, beautiful still finger, are you black?

And why are you pointing upwards?

The following text is adapted from Charles Dickens’s 1854 novel Hard Times. Coketown is a fictional town in England. [Coketown] contained several large streets all very like one another, and many small streets still more like one another, inhabited by people equally like one another, who all went in and out at the same hours, with the same sound upon the same pavements, to do the same work, and to whom every day was the same as yesterday and tomorrow, and every year the counterpart of the last and the next.

Horizontal gene transfer occurs when an organism of one species acquires genetic material from an organism of another species through nonreproductive means. The genetic material can then be transferred “vertically” in the second species—that is, through reproductive inheritance. Scientist Atma Ivancevic and her team have hypothesized infection by invertebrate parasites as a mechanism of horizontal gene transfer between vertebrate species: while feeding, a parasite could acquire a gene from one host, then relocate to a host from a different vertebrate species and transfer the gene to it in turn.
