Main Idea and Summary guide
Main Idea and Summary questions ask for the single claim the passage is built to support, or the option that best summarises the whole passage rather than one vivid part of it.
The method
- Ask what claim every paragraph or sentence is there to serve — that is the main idea.
- A correct summary covers the whole passage, not just its most memorable detail.
- Reject options that are true but too narrow, and options that are broader than the passage supports.
- A summary reports the passage; it does not add a new judgement or recommendation.
Common mistakes
- Choosing a true-but-narrow detail as the main idea.
- Choosing a topic statement that is broader than the passage.
- First-sentence bias — assuming the opening line is the main point.
- Picking a summary that smuggles in an evaluation the passage never makes.
Worked example
A real question from this category, with the verified answer and the exact evidence that decides it.
The car park is free for the first two hours. After that, each extra hour costs three pounds.
Which option best captures the passage as a whole?
Verified answer: E — Parking is free for the first two hours and then costs three pounds for each extra hour.
The evidence
The car park is free for the first two hours. After that, each extra hour costs three pounds.
The highlighted text decides the answer.
What to notice
Two facts: a free period and a later charge.
The rule
The best summary keeps both, adding or reversing nothing.
Why the others are wrong
- A — All parking in the area is free of charge.: Too broad: not all parking is free, and there is a charge.
- B — Parking is free all day on Sundays.: Added claim: no Sunday rule is stated.
- C — Parking costs three pounds from the moment you arrive.: Contradicted: the first two hours are free.
- D — The notice explains where to display your parking permit.: Unsupported focus: permits are not mentioned.
Frequently asked questions
What's the difference between the main idea and a detail?
The main idea is the point the details exist to support. A detail can be accurate yet still be too small to be the passage's central claim.
