Describe a good advertisement that you think is useful: IELTS cue card with sample answer

I recently came across a public service advertisement while waiting for the underground in London, specifically at King’s Cross station. It was a digital poster for a campaign called 'Small Acts, Big Impact', designed to encourage people to donate their unused seasonal clothing to local shelters. The visual was striking; it showed a split screen, with one side featuring a cold, shivering individual on a park bench and the other side showing a vibrant, colourful pile of winter coats, scarves, and gloves. There was no aggressive sales pitch, just a simple QR code at the bottom that directed viewers to a map of nearby drop-off points. I find this advertisement particularly useful because it bridges the gap between intention and action. Often, people want to help those less fortunate but simply do not know the logistics of how or where to donate. By providing an immediate, accessible solution in a high-traffic area, it converts passive sympathy into tangible community support. Personally, I feel quite touched whenever I see it. In a city where we are constantly bombarded with commercial ads trying to sell us luxury goods or fast food, this particular campaign stands out because it appeals to our collective sense of empathy rather than our vanity. It serves as a gentle reminder that we have the power to improve someone’s quality of life with items we no longer require. It makes the hectic daily commute feel a little more meaningful, and it actually motivated me to clear out my own wardrobe last weekend.
