an exhibition is designed which showcases different categories of audio compilations that are associated with the how-can question. There are five categories: film clips, YouTube videos, music, poetry, and the recorded audio messages from phase 2. Each has a playlist, which will be played on a smart device (e.g. tablet or phone) at its designated area at the exhibition. The audiences will be first interviewed on the how-can question, before and after, listening to the categories of their most interest.
