Command of Evidence Textual Flashcards

A student argues that the author of a passage views technological disruption as ultimately beneficial to workers. Which quotation from the passage would most effectively undermine this claim rather than support it?

Answer: 'The efficiency gains from new technologies accrue disproportionately to capital owners, leaving wage laborers with diminished bargaining power in perpetuity.'

Choice C directly contradicts the claim that the author views technological disruption as beneficial to workers by stating that efficiency gains go to capital owners and workers permanently lose bargaining power — a strongly negative assessment. Choices A, B, and D all, despite acknowledging problems, ultimately frame technological disruption as net positive for workers or society, which would support rather than undermine the student's claim.

A researcher claims that the passage supports the idea that coral reef degradation is primarily caused by ocean temperature rise rather than local pollution. The passage states: 'Elevated sea surface temperatures trigger mass bleaching events that can devastate entire reef systems within weeks, yet reefs adjacent to well-managed coastlines demonstrate measurably higher recovery rates even after severe thermal stress.' Which statement best evaluates this evidence?

Answer: The quotation weakly supports the researcher's claim because it confirms temperature causes bleaching but simultaneously implies local factors like pollution management affect outcomes.

Choice B is correct because the quotation does two things at once: it confirms temperature rise causes bleaching (supporting the claim) but the phrase 'well-managed coastlines demonstrate higher recovery rates' implies that local pollution management significantly influences reef survival — which complicates a 'primarily' attribution to temperature alone. The evidence thus only weakly supports the researcher's narrow claim. Choice A ignores the second clause entirely. Choice C incorrectly dismisses the causation element. Choice D overstates the quotation's challenge to the claim.

The following claim appears in a student's essay: 'The author implies that philosophical skepticism, taken to its logical conclusion, makes meaningful communication impossible.' Which passage excerpt, if genuine, would provide the WEAKEST support for this claim?

Answer: 'Skeptical inquiry remains indispensable as a corrective to dogmatism, even as practicing philosophers acknowledge they must operate within conventional linguistic frameworks.'

Choice C is the weakest support because it explicitly frames skepticism as a corrective tool that philosophers use while still operating within conventional language — suggesting meaningful communication remains possible alongside skeptical inquiry. This undermines rather than supports the claim. Choices A, B, and D all point toward skepticism eroding the foundations of communication: A questions shared reality, B notes that doubt undermines language itself, and D directly links denying other minds to destroying dialogue.

A passage argues that urban green spaces reduce violent crime. A student selects this sentence to support that argument: 'Studies correlating park density with reduced assault rates in Chicago neighborhoods controlled for income, policing levels, and population density, yet critics note that wealthier neighborhoods both invest in parks and experience less crime for reasons unrelated to greenery.' What is the most accurate characterization of this sentence as evidence?

Answer: It is moderate support because the controlled studies suggest correlation, but the critics' point raises a residual confounding concern that the controls may not have fully addressed.

Choice B correctly identifies the sentence as offering mixed, moderate support. The controlled studies provide meaningful evidence, but the critics raise a legitimate methodological concern — that wealth itself drives both park investment and lower crime, a confound that statistical controls may not entirely eliminate. Choice A overstates the conclusion (controlled correlation is not causation). Choice C wrongly dismisses geographic specificity as making evidence irrelevant. Choice D misreads the critics as 'definitively disproving' the link, when they only raise a concern.

A passage about Renaissance patronage includes: 'Medici commissions were rarely acts of disinterested aesthetic appreciation; contracts specified iconography, dimensions, and delivery dates with commercial precision, and patrons retained the right to reject work that deviated from agreed specifications.' A student claims this passage shows that Renaissance artists had complete creative autonomy. Which best describes the logical relationship between the evidence and the claim?

Answer: The evidence directly contradicts the claim because contractual control over iconography, dimensions, and rejection rights negates the premise of complete creative autonomy.

Choice C is correct. The passage explicitly states patrons dictated iconography (subject matter), dimensions (form), delivery dates (timeline), and held rejection rights — each element directly constrains what 'complete creative autonomy' would require. This is a direct contradiction, not a partial one. Choice A misreads 'negotiating terms' as autonomy when those terms restricted artists. Choice B incorrectly treats economic evidence as irrelevant to autonomy when contractual control is precisely what autonomy is defined against. Choice D inverts the passage's logic.

Two students debate a passage about memory consolidation during sleep. Student 1 claims the author concludes that REM sleep is more important than slow-wave sleep for memory formation. Student 2 claims the author deliberately avoids ranking the two phases. The passage reads: 'REM sleep has received the bulk of research attention regarding declarative memory, a focus that may reflect investigator bias as much as biological reality; slow-wave sleep's role in procedural and spatial memory consolidation remains, by most metrics, equally robust.' Which student does the evidence better support, and why?

Answer: Student 2, because the author explicitly attributes REM's prominence to possible investigator bias and describes slow-wave sleep's role as 'equally robust,' signaling deliberate equivalence rather than a ranking.

Choice B is correct. The author does two things that support Student 2: (1) attributes REM's dominance in research to possible investigator bias — actively undermining the idea that attention = biological importance — and (2) uses 'equally robust' to explicitly equate slow-wave sleep's role, signaling parity rather than ranking. Choice A commits the error of conflating research attention with the author's own conclusion. Choice C introduces an unsupported hierarchy of memory types not present in the passage. Choice D incorrectly treats absence of experiments as making all conclusions impossible.
