A decision before an answer
- A sentence can mention a failed attempt because it introduces a problem, qualifies a claim or illustrates a pattern. Its topic alone does not tell you its function.
- Your goal: Identify how a passage develops its central point.
Read the relationship
- Summarise each part with an action: introduces a problem, describes an approach, presents evidence or notes a limitation. The ordered actions describe structure more precisely than a list of subject nouns. Look for a shift where the author moves from background to a claim or from a claim to a qualification.
- Explain a sentence’s role in the larger argument.
Original passage: “The method is fast. However, it misses small details. A second inspection can address that limitation.” What does the middle sentence do?
It limits the speed advantage by noting a weakness.
Use the defining rule
- For the function of a marked sentence, compare what comes before and after. If it contradicts an earlier expectation and the next sentence explains that surprise, its role may be to introduce an unexpected result. It is not automatically the author’s conclusion just because it appears late.
- Distinguish a text’s purpose from its subject matter.
A passage explains why two classification methods differ. Its purpose is chiefly to:
The described explanatory action matches the purpose.
Check the conditions
- Purpose states what the author is trying to do with the information: explain a distinction, challenge an assumption, evaluate a method or describe a response. An option that merely names the topic is incomplete. An option that says persuade readers to take action needs actual advocacy, not an informative description alone.
- Distinguish a text’s purpose from its subject matter.
Original passage: “Catalogues once grouped these objects by the material from which they were made. That approach placed tools with different uses together. The revised catalogue therefore adds a function label to each entry.” Structure: describe an existing approach, identify its limitation, then explain a response. The middle sentence supplies the limitation motivating the revision; it does not claim material is irrelevant.
A detail narrowing an earlier claim is a ____.
It limits the claim rather than simply repeating it.
Apply the task format
- Distinguish an objection the author presents from a view the author endorses. Reported claims, examples and hypothetical situations can serve an argument without becoming the author’s final position. Use the passage’s wording and relationship markers to assign roles rather than imposing a favourite argument structure.
- Distinguish a text’s purpose from its subject matter.
Do not confuse what a sentence is about with what it does, or turn a described method into a recommendation without textual support.
Which answer fits this case?

Every view quoted in a passage is endorsed by its author.

- qualification 限定 — A restriction that narrows or conditions a claim.
- Identify how a passage develops its central point.
- Explain a sentence’s role in the larger argument.
- Distinguish a text’s purpose from its subject matter.
