Matching headings: how do I choose a heading?

A heading must express the main job of the paragraph: does it explain a problem, give reasons, show a change, or assess a solution?

For each paragraph, first write a short idea in your own words. Then compare it with the headings in the list. The first sentence can help, but the main idea is not always found there alone.

A word appearing in both a heading and the text is not enough for a match.

Paragraph: Early electric cars had limited range and few charging points. New batteries now allow longer journeys, while charging networks have expanded. These changes have made the cars more practical for daily use.

Suitable heading: Improvements that make electric cars easier to use.

Weak heading: The price of electricity.

Although electricity is related to the topic, the paragraph does not talk about price.

Paragraph: The new library has quiet rooms, shared desks and spaces for group discussion. Visitors can choose an area according to the kind of work they need to do.

A. Why libraries are becoming more expensive B. Spaces for different ways of working C. The history of library furniture
