SAT Command of Evidence — Textual
Pick the finding or quotation that best supports (or weakens) a claim.
How to score it
- Break the claim into its parts — the answer must hit every part, not just one.
- Match the attribute and the direction: right thing measured, right way.
- For weaken questions, find the choice that directly contradicts the conclusion, not just a tangent.
Common traps
- Evidences one clause of a multi-part claim and ignores the rest.
- Right attribute, wrong direction.
- On-topic and true, but doesn't bear on the specific hypothesis.
The 2 question types, with real examples
Supporting / weakening finding
“Which finding, if true, would most strongly support the researchers' hypothesis?”
In a 2019 study, environmental scientists analyzed the foraging behavior of bumblebees in urban gardens. Researcher Maria Gonzalez and her team claim that bumblebees demonstrate remarkable adaptability by modifying their flower preferences based on the density of competing pollinators in their immediate environment.
Which finding from the study most effectively illustrates the claim?
- ABumblebees were observed visiting an average of 47 flowers per hour across all garden sites monitored during the study period.
- BIn gardens with high honeybee populations, bumblebees shifted their attention to flower species that honeybees typically avoided, despite those flowers offering slightly less nectar.✓
- CBumblebees exhibited consistent flower preferences across different seasons, returning to the same plant species regardless of changes in garden composition.
- DThe bumblebee population in urban gardens increased by 12 percent over the two-year study period.
Choice B is the best answer because it directly demonstrates adaptability through modified behavior. The finding shows bumblebees changing their flower preferences specifically in response to the density of competing pollinators, which is exactly what the claim describes.
Illustrative quotation
“Which quotation from the work most effectively illustrates the claim?”
Historian Erika Lee has examined the implementation of the Chinese Exclusion Act of 1882 in the United States. In an essay about Lee's work, a student claims that Lee demonstrates how immigration officials applied the law inconsistently, leading to arbitrary enforcement that varied by location.
Which quotation from Lee's writing best supports the student's claim?
- A"The Chinese Exclusion Act represented the first time the United States restricted immigration based on nationality, marking a significant shift in American immigration policy."
- B"While officials in San Francisco routinely denied entry to Chinese laborers claiming merchant status, those same claims were often accepted at ports in Seattle and Portland, creating vastly different outcomes for immigrants with identical documentation."✓
- C"Chinese immigrants developed sophisticated strategies to navigate exclusion laws, including the creation of detailed coaching books to prepare for interrogation by immigration officials."
- D"Immigration officials at Angel Island processed thousands of Chinese arrivals each year, subjecting them to extensive questioning about their background and reason for entry."
Choice B is the best answer because it most effectively supports the claim about inconsistent and arbitrary enforcement varying by location. The quotation provides a specific example of how identical merchant status claims were treated differently in San Francisco versus Seattle and Portland, directly illustrating location-based variation in enforcement.
