Ask what a sentence does here
A content description says what a sentence is about. A function description says why it appears at this point in the argument. “Describes tree roots” is content; “provides a mechanism explaining the earlier observation” is function. The same factual sentence could support one claim in one passage and challenge another in a different passage.
Read one sentence backward and forward. What earlier claim does it respond to? What later conclusion depends on it? Function often becomes clear through these relationships rather than through a single cue word. All passages and exercises below are original educational material.
ORIGINAL WORKED EXAMPLE
Mechanism after observation
Original passage: Street trees sometimes reduce nearby summer temperatures. Water evaporating from their leaves absorbs heat. The effect depends on adequate soil moisture. What is the second sentence’s function?
The first sentence states an observed cooling effect.
The second supplies a physical mechanism for that effect.
The third limits when that mechanism can operate effectively.
Calling the second sentence “a limitation” confuses it with the third.
Answer It explains a mechanism underlying the cooling effect stated in the first sentence.
02 / UNDERSTAND & APPLY
Use precise role labels
A premise gives a reason to accept another statement; a conclusion is supported by other statements. A hypothesis offers a possible explanation, while evidence bears on its plausibility. An illustration makes an already stated idea concrete. A concession grants a point to an opposing position without necessarily accepting that position overall.
An objection challenges a claim or the connection between evidence and claim. A qualification restricts scope, confidence or conditions. Background establishes a setting or problem. A sentence can perform more than one role, but a question usually asks for the role most relevant to the whole passage.
ORIGINAL WORKED EXAMPLE
Concession and rebuttal
Original passage: Automated catalogs undoubtedly speed up searches. Speed alone, however, cannot settle whether a document has been classified correctly. Human review remains necessary for disputed entries. What role does the first sentence play?
The author accepts a real advantage of automated catalogs.
The following “however” prevents that advantage from establishing complete reliability.
The final claim argues for retained human review.
The first sentence is a concession, not the author’s entire conclusion or an assertion the author later denies.
Answer It concedes a benefit before limiting what that benefit establishes.
03 / UNDERSTAND & APPLY
Map change across paragraphs
Give each paragraph a functional label, then connect the labels with a verb: paragraph 2 tests paragraph 1’s hypothesis; paragraph 3 narrows the resulting conclusion. “History, experiments, future” may identify topics but does not show their logical relationship.
Distinguish sequence from argument. A historical narrative may arrange events chronologically without claiming that each caused the next. A comparison may juxtapose two accounts before favoring one; the favored account need not occupy the most lines.
ORIGINAL WORKED EXAMPLE
A revision rather than a replacement
Original passage, paragraph 1: Early scholarship described the workshop as a single master’s enterprise because every surviving object bore the same mark. Paragraph 2: Wage records identify several skilled workers. The shared mark may therefore indicate the workshop rather than a single maker, though the master could still have directed production. Describe the relationship.
Paragraph 1 presents an earlier inference from the shared mark.
Paragraph 2 introduces a different kind of evidence: wage records.
The new evidence revises what the mark can establish.
The qualification retains a possible role for the master rather than excluding it.
Answer The second paragraph uses additional evidence to qualify the first paragraph’s interpretation.

A compact map of an argument
The diagram separates a reported interpretation from the author’s evidence and qualified alternative. Arrows indicate argumentative relationships, not chronology or mathematical implication. Notice that a qualification attaches to the new conclusion; it does not restore the old conclusion unchanged.
Use this map when several voices appear. Label the owner of the first claim and identify which evidence the author endorses. The map’s exact shape will change with the passage: descriptive passages may not have a single supported conclusion.

Select a whole sentence by its role
For a select-in-passage task, the response is a sentence in the passage. First identify the requested role in your own words, then match it to a complete sentence. In these exercises sentences are numbered to make the selection unambiguous; the numbers are a teaching aid.
A sentence can contain both a concession and the claim that follows it. If the requested sentence introduces a limitation, choose the sentence doing that work, even if another sentence mentions the same subject. Do not select a neighboring sentence because it repeats a keyword.
ORIGINAL WORKED EXAMPLE
Find the limitation
Original passage: [1] The new survey reaches more coastal towns than the old one. [2] It still excludes inland settlements, where seasonal employment differs. [3] The findings should therefore not be treated as a complete national picture. Select the sentence that identifies a limitation in the sampling coverage.
Sentence 1 identifies an improvement.
Sentence 2 specifies the omitted population and its relevance.
Sentence 3 draws a conclusion from that limitation.
The question asks for the limitation itself rather than the resulting warning.
Answer Sentence 2.

Connectors guide; propositions decide
“However” signals a contrast, but you still must identify what is contrasted. “For example” usually introduces an illustration, yet the illustration might also function as a counterexample to an earlier universal claim. “Therefore” flags a conclusion, but it may be a conclusion attributed to a critic rather than endorsed by the author.
Track reporting verbs: argues, assumes, objects, concedes and suggests assign statements to speakers and indicate their status. Quotation does not equal endorsement. A passage may quote an assertion precisely to reject its basis.
ORIGINAL WORKED EXAMPLE
An opponent’s conclusion
Original passage: Critics argue that all digital editions are unreliable because files can be altered. The author replies that documented version histories can make alterations easier to detect than in unrecorded print revisions. What role does the critics’ conclusion play?
Identify the owner: critics, not the author.
Their universal unreliability claim is the target of the reply.
The reply does not deny that files can be altered; it challenges the implication that alteration makes all editions unreliable.
Answer It states the position the author challenges by distinguishing alterability from detectability.

Original practice: identify the sentence’s job
Select exactly one answer unless the question requests a sentence number.
ORIGINAL PRACTICE · 1
Original passage: Small ponds can support diverse insects. A survey of four ponds found species absent from the adjacent lake. Yet the survey cannot establish that every pond is more diverse than every lake. Function of the second sentence: A illustration/evidence; B universal conclusion; C policy recommendation.
Reveal answer & reasoning
A.
The survey supports the possibility introduced first. The final sentence limits generalization; the survey itself is not a universal conclusion.
ORIGINAL PRACTICE · 2
Original passage: [1] Scholars once dated the poem by its earliest printed edition. [2] A recently found letter quotes it twenty years earlier. [3] The earliest printed edition cannot identify the poem’s actual date of composition. Select the sentence supplying new evidence.
Reveal answer & reasoning
Sentence 2.
The letter quotation is the evidence. Sentence 1 reports the prior method, and sentence 3 draws the revised inference.
ORIGINAL PRACTICE · 3
Original passage: The device is costly to manufacture. Nevertheless, it may be economical over a long service life because repairs are rare. What is the first sentence’s function?
Reveal answer & reasoning
It acknowledges an initial disadvantage before presenting a different basis for economic evaluation.
The author does not deny high manufacturing cost. The contrast shifts from initial expense to lifetime cost.
ORIGINAL PRACTICE · 4
Paragraph 1 proposes that food supply explains a migration change. Paragraph 2 reports the same change where food supply did not change. What is paragraph 2 doing?
Reveal answer & reasoning
Presenting evidence that challenges the proposed explanation’s sufficiency or generality.
The second observation weakens an explanation intended to cover the change broadly. It does not prove that food is never relevant.
08 / UNDERSTAND & APPLY
Original practice: distinguish nearby roles
For each answer, identify the earlier or later sentence that makes your choice defensible.
ORIGINAL PRACTICE · 1
Original passage: [1] A larger archive might seem to guarantee a better historical account. [2] But many additional records repeat the same official viewpoint. [3] Expanding the range of perspectives may matter more than merely expanding the number of records. Select the sentence stating the author’s main conclusion.
Reveal answer & reasoning
Sentence 3.
Sentence 1 presents an expectation; sentence 2 challenges its assumption; sentence 3 offers the author’s comparative judgment.
ORIGINAL PRACTICE · 2
Original passage: The older model fits dry-season observations. It predicts wet-season behavior poorly. We therefore retain it for one season rather than abandon it entirely. Is the second sentence a conclusion, a limitation, or background?
Reveal answer & reasoning
A limitation of the model’s performance.
The final sentence is the decision supported by the contrast between success and failure. The second sentence supplies the negative boundary.
ORIGINAL PRACTICE · 3
Original passage: One critic calls the sculpture static. Its changing shadows, however, make the experience vary with the viewer’s position and the hour. Choose one description: A elaboration of the critic’s claim; B challenge to the critic’s characterization; C unrelated historical context.
Reveal answer & reasoning
B.
The second sentence provides a basis for questioning “static” as a description of the experience. It does not merely repeat or expand that characterization.
ORIGINAL PRACTICE · 4
Original passage: [1] The species can survive low temperatures. [2] Survival, however, does not establish successful reproduction. [3] Field studies must measure both. Select the sentence distinguishing two outcomes that might be confused.
Reveal answer & reasoning
Sentence 2.
Sentence 2 explicitly separates survival from reproduction. Sentence 3 recommends a measurement response to that distinction.

Developed original passage: integrate the full argument
The following passage and question are original educational material. Read the whole passage before answering; the five options deliberately differ in scope, attribution or argumentative role.
[1] Researchers have often explained the uneven survival of village songs by their popularity: frequently sung pieces, they reason, were more likely to be remembered. [2] Popularity surely matters, but the surviving record also reflects how collectors worked. [3] One collector transcribed only songs that fit a particular musical notation, while another visited households recommended by local officials. [4] Their collections consequently may omit widely known songs that were hard to notate or common outside those social networks.
[5] This possibility does not show that neglected songs were necessarily more popular than preserved ones. [6] It means that survival in an archive cannot by itself establish a song’s standing in the larger community. [7] Comparing independent collections, oral recollections and descriptions of performances can help identify some of the omissions. [8] Even these comparisons will remain incomplete, since the alternative records have selection problems of their own. [9] A history of musical popularity should therefore treat archival survival as one kind of evidence whose limitations must be examined, rather than as a direct ranking of past preferences.
ORIGINAL WORKED EXAMPLE
A complete-passage worked analysis
Select exactly one description of the function of sentences 3–4: A They offer examples of collecting practices and explain how those practices could distort the surviving record. B They prove that all preserved songs were unpopular. C They retract the concession that popularity matters. D They present the author’s final recommendation without supporting evidence. E They describe independent sources that eliminate all archival uncertainty.
Sentence 2 introduces collector behavior as an additional influence on survival.
Sentence 3 makes that influence concrete through notation and social-network restrictions; sentence 4 draws the consequence for omission.
A identifies both the illustration and its inferential use.
B and C exaggerate the challenge: the author explicitly preserves a role for popularity and denies a reversed ranking in sentence 5.
D confuses intermediate support with the conclusion in sentence 9; E confuses collection biases with later proposed comparisons, which are themselves limited.
Answer A. In a select-in-passage variant asking for the sentence that cautions against reversing the popularity ranking, select sentence 5.

Review through removal and replacement
Try mentally removing a sentence. Does the argument lose a reason, an exception, an illustration or a necessary definition? This removal test can clarify function. It is not absolute: an author may repeat a claim, so a sentence can reinforce a conclusion without being strictly necessary.
Then replace a concrete example with a generic label such as “counterexample to the universal claim.” If the resulting skeleton is coherent, your functional map is probably useful. If it becomes only a sequence of topics, return to the supporting and challenging relationships.

Function is relational: identify what a sentence supports, challenges or qualifies.
Track whose claim is being stated before calling it the author’s conclusion.
A select-in-passage answer is the complete sentence that performs the requested role.
