Dedicate one full body paragraph to discussing the view that increasing sports facilities is the best way to improve public health, and another separate paragraph to the opposing view that other measures are more effective. Your personal opinion should be clearly stated and developed in the conclusion, ensuring you don't become too one-sided or dismiss one view prematurely in the body paragraphs.

For the 'sports facilities' view, you could argue they promote active lifestyles and community engagement, citing examples like Singapore's ActiveSG initiative or the widespread availability of local leisure centres in the UK. For 'other measures', consider preventative healthcare campaigns (e.g., Finland's dietary guidelines success), mental health support, or urban planning that encourages walking and cycling.

The most common mistake students make on this question is narrowing 'public health' to just 'physical fitness' or 'obesity'. Public health is a much broader concept encompassing mental well-being, disease prevention, and access to healthcare. Ensure your arguments for 'other measures' reflect this wider scope, perhaps by discussing mental health services or vaccination programs, not just diet and exercise.

To effectively transition between the two contrasting views, use clear linking phrases. After discussing the benefits of sports facilities, you could introduce the opposing perspective with phrases like 'Conversely, proponents of alternative strategies argue that...' or 'While the merits of increased sports infrastructure are clear, others contend that...'. This signals a shift in argument to the examiner.

For a band 8-9 answer, examiners look for a sophisticated understanding of the nuances of 'public health' and a balanced, well-developed discussion of both sides before a clear, consistent opinion. This includes using precise topic-specific vocabulary (e.g., 'sedentary lifestyles', 'preventative healthcare'), complex grammatical structures, and a logical progression of ideas that avoids oversimplification of the issue.
