Reference 8: Function and Cross-Text Relationships

Part A: Content and Function

A sentence’s content and its job in the passage are two separate questions. Paraphrasing the content answers only the first one.

Sentence	What it says	What it does
A later study found the effect only half as large.	A study reported a smaller effect.	Limits an earlier, larger claim.
Consider the 1918 outbreak, which killed more in a single year than the war had in four.	A fact about the 1918 outbreak.	Introduces a specific case supporting a broader claim about scale.
The lab could not rule out contamination.	Contamination was not excluded.	Acknowledges a limitation in the study’s own findings.
None of this explains why the pattern reversed after 1990.	Something remains unexplained.	Shifts from settled background into the passage’s actual open question.

One sentence can support two different, compatible functions at once. “The bridge outlived every engineer who doubted it” can supply evidence for a claim about the bridge’s durability, and it can also supply a note of irony about the skeptics. Which function is the relevant one depends on what the question is actually asking the sentence to do, not on which function is more interesting.

Part B: Cross-Text Relationships

Two authors agreeing on a fact does not mean they agree on anything else. Find the exact place the agreement stops.

Same fact, different cause. A marine biologist reports that a kelp forest declined sharply after a spike in the local sea urchin population, and attributes the decline to urchins overgrazing the kelp directly. A second researcher confirms the same urchin spike and the same kelp decline, but attributes both to an earlier collapse in the sea otter population, since otters are the urchins’ main predator. Both texts agree on what happened. They disagree on what actually drove it.

Same evidence, different interpretation. An economist points to a rise in remote-work job postings as evidence that companies are permanently moving away from office space. A second economist, examining the same postings, argues they reflect a temporary hiring tactic used to attract talent during a competitive market, not a lasting structural shift. Both texts are reading identical data. They are not reading it the same way.

Same direction, different strength. A nutritionist states that a diet higher in fiber is linked to modestly better long-term health outcomes in the population studied. A second nutritionist reviewing similar data argues that fiber intake is one of the single strongest predictors of long-term health outcomes. Both texts report the same direction of effect. One claims far more about its size than the other does.

Partial agreement, different reach. A historian argues that a canal’s construction transformed the regional economy within a decade. A second historian agrees the canal mattered locally but argues its effect never reached the wider region, only the towns directly on its route. Both texts agree the canal had a real effect. They disagree entirely about how far that effect actually traveled.

Before answering a cross-text question, name the exact point where the two texts stop agreeing. It is almost never “everything.”
