Common trap
Only writing that older people increase healthcare cost ignores experience, volunteering, or later retirement.
This IELTS Task 2 question should not start with memorising a model essay. First decide who the prompt concerns, what it compares, and whether it asks for cause, evaluation, or trade-off.
Diagnose the prompt before writing the full essay.
Only writing that older people increase healthcare cost ignores experience, volunteering, or later retirement.
If the essay only has cost and no active ageing, the position is thin.
First decide whether the prompt asks about financial burden, family responsibility, employment, or social value.
Write one ageing chain: age group -> need or contribution -> social effect -> policy response.
