Production of Writing: Purpose, Unity, and Cohesion
Production of Writing questions ask whether a passage does its job: whether a sentence belongs, whether a paragraph stays on topic, whether ideas flow in a logical order, and whether an introduction or conclusion actually does what it claims. Treat every passage as an argument with a job to do.
Concepts you must command
- Topic and purpose: identify the passage's main point in one sentence before judging any detail.
- Relevance: a sentence earns its place only if it supports the stated purpose. Interesting but off-topic details are wrong answers.
- Cohesion: transitions, pronouns, and repeated key terms must point backward and forward consistently.
- Organization: check chronology, cause and effect, general-to-specific, and problem-to-solution order.
- Adding, deleting, and revising: know what a specific addition or deletion accomplishes, not just that it changes length.
Traps
- True but irrelevant: an option that states a fact from the passage but doesn't serve the question's stated goal.
- Vague relevance: choices like "adds interesting detail" without connecting to purpose.
- Reversed transitions: "however" where the second sentence actually continues the first idea.
- Wrong-scope conclusions: a concluding sentence that introduces a brand-new topic.
Worked rule of thumb
A question asks whether to delete a sentence describing a scientist's childhood hobby. Ask: does the paragraph's purpose concern the scientist's research? If yes, the hobby is true but off-purpose-delete it. The justification must name the paragraph's purpose, not just say "it's unrelated."
When two answers both seem plausible, choose the one whose reasoning explicitly ties the change to the passage's stated goal.
