Matching headings: find the main idea, not a keyword

Here you're given a list of headings and must match one to each paragraph. The headings always outnumber the paragraphs, so some are never used - and several are deliberately built to trap word-matchers. The skill being tested is main idea, not vocabulary spotting. A heading that repeats a striking word from the paragraph is, more often than not, the wrong answer.

What a "main idea" actually is

Every well-written paragraph has one controlling point, and the supporting sentences merely illustrate it. Your job is to name that controlling point. A useful question to ask: "If this paragraph had to keep only one sentence, which one would it be?" The heading should match that sentence, not the colourful example next to it.

The method, step by step

1. Skim each paragraph and, in your own words, write a 5-7 word summary of its overall point - not its first sentence, its whole point.
2. Read all the headings once before matching anything, so you know the full field and can spot near-duplicate headings designed to split your decision.
3. Match the easy ones first. Confident pairs reduce the options for the hard ones - matching headings is partly a process of elimination.
4. For a tricky paragraph, ask: "Which heading covers the WHOLE paragraph, not just one sentence?" Cross out a heading once it's used (unless the rubric says options may repeat - they almost never do here).
5. Cover the early sentences and read the rest. Writers often hide the true topic in the middle or the conclusion, while the opening is just a hook or a claim that will be overturned.
6. Leave near-twin headings until last. When two headings look similar, the difference between them is usually one word (causes vs effects, benefits vs risks). Decide which word the paragraph actually argues.

Worked example 1 - keyword bait

Paragraph: It is tempting to assume the printing press spread literacy overnight. In fact, for the first century after Gutenberg most printed books were religious works read aloud to congregations who could not read themselves. Only as cheaper paper and vernacular titles appeared did private, silent reading slowly take hold.

Candidate headings:

• i. The invention of the printing press
• ii. Why literacy rose more slowly than expected
• iii. Religious texts of the medieval church

The paragraph mentions the press (i) and mentions religious books (iii) - both are keyword bait. But the whole point is that literacy spread gradually, contrary to the "overnight" assumption. The answer is ii. Headings i and iii each grab a single detail, not the argument.

Worked example 2 - telling near-twin headings apart

Paragraph: Early commuter railways were celebrated for freeing workers from the slums beside the factories. Yet the same lines hollowed out city centres: those who could afford a fare moved to new suburbs, leaving the poorest behind in increasingly neglected districts. The railway did not so much solve overcrowding as relocate its consequences.

Candidate headings:

• i. How railways improved workers' housing
• ii. An unintended social cost of commuter railways
• iii. The engineering behind early railways

Heading i is the hook the paragraph opens with - but it then argues the opposite. Heading iii is never discussed. The controlling point is the final sentence: the railway "relocated" its problems. That is a social cost, so the answer is ii. The trap is stopping at the cheerful first sentence.

Useful paraphrase tactic

Because headings restate the paragraph in fresh words, practise turning concrete details into abstract labels:

• a paragraph full of dates and inventors → "The development of X over time"
• a paragraph weighing pros and cons → "Assessing the value of X"
• a paragraph describing a problem then a fix → "A solution to X"

Train your eye to convert examples into categories - that conversion is exactly what the heading has already done.

Common mistakes

• Keyword magnets. A heading repeating a word from the paragraph's first line is usually a distractor. The press is named, but the paragraph isn't about the invention.
• First-sentence trap. Topic sentences can be a hook or even a claim the paragraph goes on to reject ("It is tempting to assume..."). Read past it before deciding.
• Too narrow / too broad. Reject headings that cover only part of the paragraph, and those so general they'd fit three paragraphs equally well.
• Picking between twins on a single word. When two headings are close, don't choose on gut feel - locate the sentence that decides between cause and effect, benefit and drawback.
• Leaving the example. When a sample answer is shown for one paragraph, that heading is used up - strike it off your list immediately.

Try it

On a passage at /ielts/reading, cover the headings and write your own one-line title for each paragraph first. Then match your titles to the closest official heading, doing the confident ones before the hard ones. You'll pick the idea, not the word.
