Paragraph: “The first public parks were not created for exercise. In nineteenth-century industrial cities, reformers argued that open spaces would act as the city’s ‘lungs’, clearing the polluted air that was then blamed for disease. Sports facilities came much later, and many early parks actually banned ball games on their lawns.”
Headings: i The rise of team sports · ii An unexpected original purpose · iii Designing parks for children · iv The health risks of industrial cities
Answer: ii. The paragraph is about why parks were first created, and the opening sentence signals that the reason is surprising (“not created for exercise”). Heading iv picks up one supporting detail (pollution and disease). Heading i matches the words sports and ball games, but the paragraph says sport came later. A heading must cover the whole paragraph.
