Explain why an author includes a detail
Identify what a detail does in a passage: illustrate a change, support an explanation, or establish a contrast. Practice with original short texts.
Before you begin
Useful foundation: Identify a paragraph's topic and understand the sentences around a quoted detail.
Your goal: Explain a detail's function in context without inventing the author's private motives.
For a purpose question, ask what the detail helps the reader understand. Look at nearby claims and transitions. An answer about what the detail says may be accurate but still fail to explain why it is included.
Work through an example
The town's first bus timetable fit on a single card. Today, the route map fills a wall at the station. That contrast reflects decades of expansion as new neighborhoods connected to the center. Why mention the single card?
- Read beyond the quoted detail. The next sentence describes a much larger current map.
- The phrase “That contrast” explicitly links the card and the wall map.
- The following explanation names the point of the contrast: the network expanded over decades.
- The card detail establishes a small starting point so the reader can understand the scale of later growth. It does not prove that the old service was better.
Try a question yourself
The repair café does more than fix broken objects. On Saturday, a volunteer showed a visitor how to replace a loose switch, then watched as the visitor completed the repair herself. Such exchanges turn a quick repair into a chance to learn a reusable skill.
Choose an answer, then check your reasoning. This public practice is not saved.
Read all answer explanations
illustrate how the café helps visitors learn through a repair. — correct answer: The opening claim says the café does more than fix objects, and the final sentence names learning as the added benefit. The switch example illustrates that point.
explain every technical step needed to replace a switch.: The passage gives no step-by-step wiring instructions. Its focus is the teaching exchange rather than the technical procedure.
show that visitors no longer need help with any repair.: One visitor completing one repair with guidance does not support independence on all future repairs.
argue that replacing an object always costs more than repairing it.: The passage makes no price comparison. An economic argument would require evidence not included here.
What to do next
For another paragraph, label a detail as an example, contrast, definition, or evidence. Explain how it connects to the surrounding sentences.
Revisit the idea in a week using a different question. Repeating this example can help you understand it, but remembering its answer is not evidence of learning a new problem.
