SAT Reading and Writing Quiz: Transitions

Scientists expected the comet's tail to brighten as it neared the sun, and early models predicted it would be visible even from brightly lit cities.  , dust shed from the comet absorbed sunlight, leaving the tail far dimmer than predicted and forcing astronomers to revise public viewing guides.

Which choice completes the text with the most logical and precise transition?

While studying a family archive, a historian uncovered letters that trace a migration from a rural village to a port city, offering vivid accounts of wages, crowded boardinghouses, and the slang of dockside markets; the correspondence spans three generations and reveals how names, foods, and holidays changed as relatives settled in new neighborhoods.   she cataloged hundreds of photographs that document festivals, storefronts, and street scenes, allowing readers to visualize the transformations the writers describe over decades.

A nutrition study found that people who ate more legumes tended to have lower LDL cholesterol, but the researchers cautioned that the data were correlational and could reflect broader dietary patterns.   they ran a smaller randomized trial and observed a modest LDL reduction when legumes replaced refined grains, strengthening the case for a causal effect.

Sociologists studying volunteerism found that people are more likely to donate time when asked directly by someone they know than when they see a general advertisement.   organizations often recruit "community captains" who make personal requests, even though this approach requires more coordination than mass messaging.

A river restoration team removed an obsolete dam to improve fish migration and restore sediment flow to downstream wetlands.   within two years, native fish counts increased and the wetlands began rebuilding naturally as seasonal floods deposited new layers of silt.

When a river is straightened to speed drainage, water often flows faster and erodes the channel bed, which can reduce habitat complexity for aquatic species.   restoration projects sometimes reintroduce meanders and floodplain connections, slowing the current and creating pools and wetlands that support greater biodiversity.

Urban ecologists note that planting diverse native species can increase a park's resilience to pests, since no single insect can easily devastate every tree.   the same diversity can complicate maintenance, because crews must learn different pruning schedules and soil requirements rather than applying one uniform plan across the entire site.

Researchers analyzing ice cores observed that atmospheric carbon dioxide levels rose sharply during periods when global temperatures also increased.   this correlation alone does not establish which variable initiated each change, so scientists use multiple lines of evidence to infer causal mechanisms.

Which choice completes the text with the most logical transition?

A company replaced its open-plan office with smaller shared rooms after employees reported frequent interruptions and difficulty concentrating.   surveys conducted six months later showed higher reported focus, but they also revealed lower cross-team communication, suggesting a trade-off rather than a simple improvement.

A historian argues that the rise of inexpensive printed pamphlets in the eighteenth century broadened political participation by making arguments accessible beyond elite salons.   this expansion did not automatically produce informed debate, since many pamphlets relied on sensational claims designed to provoke outrage rather than careful reasoning.

Which choice completes the text with the most logical transition?

Literary critics often describe the narrator of a novel as "reliable" when the account seems consistent and well supported by events in the story, encouraging readers to accept the narrator's judgments.   in some modernist works, the narrator's precise details can coexist with subtle omissions, so the voice appears trustworthy even as it steers readers away from alternative interpretations.

Some economists argue that raising the minimum wage can increase consumer spending because low-wage workers are likely to spend additional income quickly.   if businesses respond by cutting hours or positions, total earnings for the affected group may not rise as much as the higher wage rate alone would suggest.

In controlled experiments, participants who slept at least seven hours performed better on tasks requiring sustained attention than those who slept less.   the researchers cautioned that sleep duration was self-reported, so measurement error could partially inflate the apparent advantage of longer sleepers.

Geologists explain that river deltas grow when sediment deposition outpaces erosion, gradually building new land at the river's mouth.   when upstream dams trap sediment, the delta may begin shrinking even if the river's water flow remains steady, because less material reaches the coast to replace what waves remove.

Which choice completes the text with the most logical transition?

In physics, simplifying assumptions—such as treating a pendulum's string as massless—can make a model solvable while still yielding useful predictions for many situations.   when the same assumptions are applied to very long pendulums or large swing angles, the model's errors can grow, because neglected factors like air resistance and nonlinearity become more influential.

In a study of urban heat islands, researchers found that neighborhoods with more tree canopy had lower daytime surface temperatures even when building density was similar.   the same neighborhoods also showed reduced nighttime cooling, likely because dense vegetation can trap longwave radiation and slow the release of stored heat after sunset.

A company's internal survey reported high employee satisfaction with remote work, citing flexibility and fewer commuting hours as major advantages.   the same survey also noted that newer employees struggled to find mentors, since casual interactions that once happened in hallways were harder to replicate online.

In physics, increasing the temperature of a gas in a sealed container typically raises its pressure because faster-moving molecules collide with the container walls more often.   if the container can expand, the pressure may remain nearly constant as volume increases instead.

A robotics lab improved a drone's obstacle avoidance by training its navigation model on a larger and more varied set of simulated environments, including different lighting and weather conditions.   field tests revealed that the drone still struggled near reflective glass surfaces, where sensor readings became ambiguous and the simulation data had not captured the same optical artifacts.

A climate modeler emphasized that improving resolution can help simulations capture local rainfall patterns influenced by mountains and coastlines.   higher resolution also requires substantially more computing power, which can limit the number of scenarios researchers can run when exploring uncertainty.
