Command of Evidence Textual Flashcards

A student claims: 'The author believes that standardized testing fails to measure true student potential.' Which evidence from a passage would best support this claim?

Answer: 'Research shows that test scores correlate more strongly with family income than with students' actual cognitive abilities, suggesting the tests measure socioeconomic advantage more than innate potential.'

The correlation between scores and family income rather than cognitive ability directly supports the claim that tests fail to measure true potential.

Read this passage: 'In 1854, physician John Snow mapped cholera cases in London and found they clustered around a specific water pump. Removing the pump handle ended the outbreak. His work established that cholera spread through contaminated water, overturning the prevailing miasma theory that disease spread through bad air.' A student argues: 'Snow's work fundamentally changed the scientific understanding of how disease spreads.' Which evidence from the passage best supports this?

Answer: 'overturning the prevailing miasma theory that disease spread through bad air'

Overturning the prevailing theory is the most direct evidence of fundamentally changing scientific understanding — it shows an existing paradigm was replaced.

A student reads a story where a character named Dara always gives her lunch to classmates who forgot theirs, volunteers at a local shelter, and anonymously donates her allowance to her school's supply fund. The student claims: 'Dara is motivated by compassion rather than recognition.' Which detail from the story provides the strongest evidence?

Answer: Anonymously donating her allowance to the school fund

The anonymous donation is the strongest evidence of compassion without desire for recognition — anonymity specifically removes the possibility of social reward.

A passage about ocean acidification states: 'The ocean absorbs approximately 30% of human CO2 emissions. When CO2 dissolves in seawater, it forms carbonic acid, lowering the ocean's pH. Since industrialization began, ocean pH has fallen from 8.2 to 8.1 — a 26% increase in acidity. This threatens shellfish and coral by dissolving the calcium carbonate structures of their shells and skeletons.' A student claims: 'Ocean acidification poses a specific, measurable threat to marine organisms.' Which evidence best supports this?

Answer: 'This threatens shellfish and coral by dissolving the calcium carbonate structures of their shells and skeletons.'

The sentence identifying the specific organisms threatened (shellfish, coral) and the specific mechanism of harm (dissolving calcium carbonate structures) directly supports a 'specific, measurable threat to marine organisms.'

A student wants to find textual evidence that an author is using irony. The passage reads: 'The self-proclaimed champion of the working class arrived at the fundraiser in a $12,000 suit, stepped out of a rented limousine, and greeted the $500-per-plate dinner guests warmly.' What makes this passage function as evidence of irony?

Answer: The contrast between the 'champion of the working class' identity and the luxurious details creates ironic distance

Irony is created by the gap between the 'working class champion' identity claim and the lavish, wealthy lifestyle details — the two are in direct contradiction.

A passage about the printing press states: 'Before Gutenberg, a single Bible might take a monk three years to copy by hand. Within decades of the press's introduction, Venice alone had over 150 printing shops, and books that once cost a year's wages could be purchased for a few days' pay.' A student argues: 'The printing press dramatically increased access to written material.' Which part of the passage provides the most specific, quantifiable evidence?

Answer: 'books that once cost a year's wages could be purchased for a few days' pay'

The cost comparison (a year's wages to a few days' pay) provides the most specific economic evidence of dramatically increased accessibility.

A student reads this claim from a passage: 'While the new curriculum has been praised by administrators, teachers in the classroom have a different view.' The passage then quotes three teachers who each describe the curriculum as overwhelming and poorly sequenced. What is the purpose of the teacher quotes as evidence?

Answer: To provide specific, firsthand evidence that supports the claim of a disconnect between administrative praise and classroom experience

The teacher quotes provide firsthand classroom experience that evidences the gap between administrative perspective and on-the-ground reality — exactly what the claim announces.

Read this: 'The mayor argued that the new stadium would create 2,000 permanent jobs and generate $80 million annually for the local economy. An independent analysis commissioned by the city council found that comparable stadiums in similar cities had created an average of 340 permanent jobs and generated $12 million annually.' A student argues: 'The mayor's economic projections are not supported by evidence.' Which aspect of the independent analysis most effectively supports this argument?

Answer: The gap between 2,000 projected jobs and 340 actual average jobs, and between $80M and $12M actual revenue

The specific numerical gap — 2,000 vs. 340 jobs and $80M vs. $12M revenue — directly shows the mayor's projections exceed real-world comparables by a large margin.
