SAT Reading & Writing Practice Questions

Question 1

The phenomenon of bioluminescence—the production and emission of light by living organisms—has fascinated scientists for centuries. While fireflies are perhaps the most familiar bioluminescent creatures, the majority of organisms that produce light actually live in the ocean. Deep-sea fish, jellyfish, and certain species of bacteria use chemical reactions to generate light, typically through the interaction of a light-emitting molecule called luciferin with an enzyme called luciferase. This ability serves various purposes: some fish use bioluminescence to attract prey, while others employ it as a defense mechanism to startle predators or to camouflage themselves against the faint light filtering down from the surface. Recent research has revealed that bioluminescence evolved independently at least forty different times across various species, suggesting that the ability to produce light offers significant evolutionary advantages in diverse environments.
Which finding, if true, would most directly support the claim that bioluminescence provides significant evolutionary advantages?
A. Bioluminescent organisms are found in both shallow and deep ocean waters across all major ocean basins.
B. The chemical structure of luciferin varies considerably among different bioluminescent species.
C. Species that developed bioluminescence showed higher survival and reproduction rates compared to closely related non-bioluminescent species in similar environments.
D. Scientists have successfully replicated the bioluminescent chemical reaction in laboratory settings.

Question 2

In her 1962 book Silent Spring, marine biologist Rachel Carson warned of the environmental dangers posed by synthetic pesticides, particularly DDT. Her work has often been characterized as alarmist by critics who point to her dire predictions about ecosystem collapse. However, this characterization misrepresents Carson's actual approach. Rather than making absolute proclamations, Carson carefully qualified her statements with phrases such as 'evidence suggests' and 'studies indicate,' and she consistently acknowledged uncertainties in the scientific data available at the time. Her primary goal was not to incite panic but to advocate for more rigorous testing and regulation of chemical pesticides before their widespread use. By examining the nuanced language Carson employed throughout Silent Spring, readers can see that she was calling for precautionary measures based on emerging evidence, not issuing apocalyptic warnings based on speculation.
Which choice best describes the function of the underlined sentence in the text as a whole?
A. It introduces a perspective that the remainder of the text will challenge and refute.
B. It provides historical context for understanding Carson's influence on environmental policy.
C. It presents the main argument that the text will develop through additional examples.
D. It acknowledges a limitation in Carson's methodology that subsequent research has addressed.

Question 3

Urban planners in Copenhagen have implemented an innovative approach to reducing traffic congestion and carbon emissions. The city has invested heavily in cycling infrastructure, creating over 390 kilometers of dedicated bike lanes. This investment has yielded impressive results. Today, approximately 62% of Copenhagen residents commute to work or school by bicycle daily. The city has also seen a significant decrease in air pollution levels. Healthcare costs related to respiratory illnesses have declined. These outcomes demonstrate that prioritizing sustainable transportation can produce multiple benefits for urban communities.
The writer wants to add a sentence after the underlined sentence to provide a logical transition and strengthen the connection between ideas. Which choice most effectively accomplishes this goal?
A. In addition, many residents report enjoying their bicycle commutes more than driving.
B. Moreover, the environmental benefits have been accompanied by improvements in public health.
C. Cycling has become an integral part of Copenhagen's cultural identity and tourism appeal.
D. The bike lanes are carefully designed to separate cyclists from motor vehicle traffic.

Question 4

The ancient Library of Alexandria, established in the third century BCE, was one of the largest and most significant libraries of the ancient world. Scholars from across the Mediterranean region traveled to Alexandria to study its vast collection of texts, which reportedly numbered in the hundreds of thousands. The library's destruction, however, remains shrouded in mystery. Some historians attribute its demise to Julius Caesar's fire in 48 BCE, others point to various later incidents, including religious conflicts in the third and fourth centuries CE. Despite the uncertainty surrounding its end, the Library of Alexandria's legacy as a center of learning and knowledge preservation continues to inspire modern institutions dedicated to scholarship and education.
Which choice completes the text so that it conforms to the conventions of Standard English?
A. BCE, others
B. BCE; others
C. BCE. Others
D. BCE others

Question 5

Economist Raj Chetty and his research team have conducted extensive studies on economic mobility in the United States, examining how children's economic outcomes compare to those of their parents. Using data from millions of families, Chetty's research has revealed significant geographic variation in upward mobility: children growing up in some cities have much better chances of earning more than their parents than children in other cities. The research identifies several factors associated with higher mobility, including less residential segregation, lower income inequality, better schools, stronger family structures, and higher levels of social capital. Interestingly, these factors affect not only poor children but all children in a community, suggesting that the characteristics of one's childhood environment have broad impacts on economic outcomes regardless of individual family income.
Based on the text, what can most reasonably be concluded about Chetty's findings regarding economic mobility?
A. Geographic location is the sole determinant of whether children will earn more than their parents.
B. Children from wealthy families are unaffected by the characteristics of their surrounding community.
C. The community-level factors that promote economic mobility benefit children across different income levels.
D. Residential segregation has a stronger impact on economic mobility than school quality does.
