SAT Pastpaper with Solutions

While researching a topic, a student has taken the following notes:
· In a 2021 study, biologists Maria Chen and David Kim investigated the impact of organic fertilizer on the growth of Arabidopsis thaliana plants.
· The team tested 100 plants treated with organic fertilizer and monitored their growth over 60 days.

Researchers studied the defensive behaviors of cuttlefish when confronted by predators. They observed that 40% of cuttlefish in their experiments rapidly changed their skin color to bold, high-contrast patterns when approached by sharks. These patterns included alternating black-and-white stripes and pulsating spots. In some species, color changes were accompanied by the release of a cloud of ink. The researchers hypothesize that the sudden, vivid color displays in cuttlefish without ink release function primarily to confuse predators by disrupting their ability to track movement, rather than to camouflage or signal toxicity.

 Which finding, if true, would most directly support the researchers'hypothesis?

In Shakespeare's Macbeth, the relationship between Macbeth and Lady Macbeth deteriorates significantly after they commit regicide to seize the throne. Initially united in ambition, their partnership frays as guilt and paranoia consume them. This breakdown is particularly evident when___________.

The following text is adapted from a 1923 speech by suffragist Alice Paul.

When I stood in London in 1910, protesting for womens rights, I scarcely imagined that the tactics we devised there---hunger strikes, parades, and public petitions---would one day ignite a movement that reshaped the United States. This reflection underscores Pauls belief that strategies forged in one context can transcend borders and time.

Which choice best describes the function of the underlined sentence in the text as a whole?

Though less widely recognized than bestselling authors of her generation, Chilean writer Marta Vásquez has garnered profound admiration from prominent literary voices. Critic Elena Martínez, in her 2023 essay collection Voices of the Unseen, argues that Vásquez's novel The Salt of Memory "redefines the boundaries of magical realism" and deserves a place alongside the works of Gabriel García Márquez. Similarly, Nobel laureate Mario Vargas Llosa praised Vásquez's "unerring ability to fuse history with myth" during a 2021 interview, noting that he revisits her writing annually for inspiration. While Vásquez's novels have never topped sales charts, this acclaim underscores her unique position in contemporary literature.

In the early 20th century, many cities in Europe and North America experienced a boom in the popularity of vaudeville theater, a variety show that included acts like comedy, music, dance, and drama. These shows often catered to a wide audience and were performed in large urban theaters. Recently, historians have examined the role of vaudeville in shaping popular entertainment by looking at programs and reviews from the era. One key finding from this research is that vaudeville performances were often heavily influenced by the tastes of the audience, with performers adjusting their acts based on the reactions they received. This suggests that vaudeville performances were highly interactive and tailored to the specific interests of the audience in attendance.

Which statement, if true, would most strongly support the historians'argument?

Scientists have long been interested in how urban environments influence wildlife behavior. A recent study led by Dr. Elena Martinez focused on the adaptation of sparrows in metropolitan areas. Martinez's team observed sparrow populations in 10 major cities, tracking changes in nesting habits, feeding patterns, and vocal communication over five years. To assess the impact of noise pollution, the researchers compared urban sparrows to a control group in rural habitats. They discovered that urban sparrows developed shorter, higher-pitched songs compared to their rural counterparts, likely to overcome background noise from traffic and human activity.

Which choice best describes the overall structure of the text?

Consumers increasingly demand sustainable packaging for products, prompting companies to explore alternatives to traditional plastic. While compostable bioplastics and paper-based materials have emerged as promising solutions, they come with challenges. Many compostable materials require industrial rather than home composting conditions to break down properly, limiting their environmental benefits. Similarly, paper-based packaging, despite being recyclable, often requires additional coatings to maintain durability, complicating recycling efforts. Although researchers are developing novel materials to address these issues---such as bio-based films with improved decomposition rates---__________.

Japanese architect Kenzo Tange's work evolved significantly over the course of his career, spanning from the 1940s to the 1990s. Initially, he was deeply influenced by Le Corbusier's modernist principles, which emphasized functionalism, rigid geometric structures, and reinforced concrete, as seen in his early design for the Hiroshima Peace Memorial Museum. However, by the 1960s, Tange had embraced a more flexible, futuristic vision, incorporating modularity and organic, adaptable forms, as exemplified in his master plan for Tokyo Bay. This shift marked a departure from his earlier strict modernist approach toward a more experimental and dynamic architectural philosophy.

Information in the text best supports which statement about the design of the Hiroshima Peace Memorial Museum?

Text 1 Traditional studies on group cohesion have largely focused on established social units, such as families, workplaces, and long-term friendships. However, sociologist Mira Kandel and colleagues have shown that brief, spontaneous interactions---such as exchanging pleasantries with a fellow commuter---can also foster a sense of connection and belonging. Their study found that individuals who engaged in casual conversations with strangers reported greater overall satisfaction with their daily social experiences.

Text 2 Social network analysis often categorizes interpersonal connections based on frequency and depth of interaction. Strong ties, such as those with close friends and family members, are characterized by frequent, meaningful exchanges, while weak ties, such as acquaintances, involve less frequent but still recurring interaction. Connections that do not meet these criteria are typically classified as inconsequential for social bonding.

Based on the texts, what would Kandel and colleagues (Text 1) most likely say about the categorization in Text 2?

Despite the critical role of mycorrhizal fungi in facilitating nutrient exchange between plants, traditional agricultural practices emphasizing monoculture and synthetic fertilizers have led to a ______ of soil biodiversity, inadvertently destabilizing ecosystems. Recent agroecological studies, however, demonstrate that crop rotation and fungal inoculation can restore symbiotic networks, boosting resilience.

Which choice completes the text with the most logical and precise word or phrase?

Urban rooftop gardens are often promoted for their ability to reduce building energy consumption by providing natural insulation. However, data from thermal efficiency studies in City Y demonstrates that in high-rise buildings with extensive glass facades, the cooling costs during summer months remained unchanged or even increased. This implies that the widely recognized advantage of rooftop gardens is not always _______; researchers observed that the gardens' soil and vegetation retained heat, counteracting their insulating benefits.
