Topic-sentence test · eliminating detail-level headings
Topic & Why It Matters
Matching Headings questions ask you to connect each paragraph with the heading that best summarises its main idea. They are common in IELTS Reading because they test fast global understanding: you must see what a paragraph is doing without getting trapped in every detail.
Many learners lose marks because they read too slowly, focus on isolated vocabulary, or choose a heading that matches only one sentence. The skill is to move from detail to function: identify the paragraph's central purpose, then choose the heading that covers all of it.

What Matching Headings tests
Matching Headings asks you to choose the best title for each paragraph or section. It tests whether you can identify the controlling idea of a whole paragraph, not just recognise a repeated word or an interesting detail.
A heading must cover the whole paragraph
The correct heading usually summarises the paragraph's main function: problem, cause, result, comparison, solution, warning, or example. If a heading only matches one sentence, it is normally a distractor.
Topic sentences are useful but not absolute
Many IELTS paragraphs announce their main idea in the first or second sentence. However, some paragraphs begin with an example or background before shifting to the real point. Always check the final sentence as well, because it often states the conclusion or contrast.
Headings are deliberately broader than keywords
Correct headings often paraphrase the paragraph with abstract nouns such as limitation, consequence, explanation, response, or comparison. A heading that repeats a vivid keyword from the paragraph may be tempting but too narrow.
Options are not reused
In standard Matching Headings tasks, each heading can be used only once and there are usually more headings than paragraphs. Eliminating headings you have already used reduces the option pool for later paragraphs.
Step-by-Step Strategy
1
Read the heading list first
Quickly scan the headings and underline the main noun in each one: cause, effect, concern, solution, comparison, history, prediction. Do not try to memorise every word.
2
Read one paragraph for its function
Read the first and last sentence carefully, then skim the middle. Ask: What is this paragraph doing in the passage? Explaining a problem? Giving evidence? Describing a response?
3
Write a two- or three-word margin title
Before looking back at the options, create your own rough title such as 'unexpected cost' or 'new regulation'. This protects you from choosing a heading just because it shares vocabulary.
4
Match meaning, not wording
Choose the option that expresses your rough title in broader academic language. Check that every major sentence in the paragraph fits under that heading.
5
Reject detail-level headings
If a heading matches only one example, number, name, or minor explanation, cross it out for that paragraph. IELTS distractors often come from real details.
6
Use elimination at the end
After answering all paragraphs, revisit any uncertain items with the remaining headings. Compare close options by asking which one covers more of the paragraph.
Common Pitfalls
Mistake
Corrective Rule
Matching a repeated keyword
A shared word is not enough. The heading must summarise the whole paragraph's main idea.
Ignoring contrast markers
Words such as however, yet, although, and instead often signal the real direction of the paragraph. The heading should follow the contrast, not the setup.
Choosing an example as the main idea
Examples support the topic; they rarely are the topic. Ask what the example proves.
Reading every sentence at full speed
Matching Headings rewards selective reading. Focus on topic sentences, concluding sentences, and repeated abstract ideas.
Using the same heading twice
Unless the task explicitly says otherwise, each heading is used once only. Cross off used headings immediately.

The Changing Role of Public Libraries~405 words
A
For much of the twentieth century, public libraries were defined by the size of their printed collections. A successful library was one that could offer residents long shelves of novels, reference works, newspapers, and specialist magazines. In recent decades, however, the measure of success has begun to change. Many library systems now judge their value less by the number of books they store and more by the range of services they provide: internet access, language classes, homework support, job-search workshops, and community events.
B
This expansion has partly been driven by inequality in digital access. Although smartphones are widespread, many people still lack a reliable computer, a quiet workspace, or a stable broadband connection at home. For job applications, online government forms, remote interviews, and school assignments, a phone is often insufficient. Libraries have therefore become essential digital entry points, especially for older residents, recent migrants, students from crowded households, and people seeking work.
C
The changing role of libraries has also altered the skills expected of library staff. Traditional cataloguing knowledge remains useful, but staff are now frequently asked to troubleshoot printers, guide users through unfamiliar websites, support early literacy programmes, and manage public events. Some librarians describe their work as closer to social navigation than book management, because visitors often arrive with complex practical problems rather than simple requests for a title or author.
D
Not everyone welcomes this broader mission. Critics argue that libraries risk becoming underfunded substitutes for schools, employment agencies, and social services. When a library is asked to solve every local problem, they say, its original educational purpose can become blurred. Supporters reply that access to information has always been the library's core mission, and that helping people use digital systems is simply the modern version of that responsibility.
E
A further challenge is that library use is often measured in outdated ways. Counting book loans alone can make a busy library appear to be declining, even when study spaces are full and computer sessions are heavily booked. Some cities have started recording attendance at classes, use of meeting rooms, Wi-Fi sessions, and staff assistance with online forms. These broader indicators may offer a more accurate picture of how libraries serve communities today.

Why is matching a repeated keyword dangerous in Matching Headings questions?
Which two parts of a paragraph should you read especially carefully before choosing a heading?
How can writing your own short margin title help you avoid distractors?
Answers:
(1) A repeated keyword may come from a supporting detail rather than the paragraph's main idea. The correct heading must cover the whole paragraph.
(2) Read the first or second sentence and the final sentence especially carefully. Together they often reveal the paragraph's topic and conclusion or contrast.
(3) A rough margin title forces you to identify the paragraph's function before seeing the options again, so you match meaning instead of surface vocabulary.
