n ounce of prevention is worth a pound of cure" It means doing things ahead of time is better than leaving it to last minute.. Take a car for example. Routine maintenance is better than scrambling to fix it in a hurry when it breaks down from lack of attention. Same for houses, relationships. The words can be applied in a huge variety of areas.

Since the word "cure" is used, it sounds medical. However, this prompt could also be taking in direction of mental illness or physical illness. You could write on anything from suicide (better to prevent depression and suicidal thoughts than to lose a person) or cancer (better to have drugs or something that can prevent cancer than to go through chemotherapy). But you could also stretch the prompt to talk about other things like better to take steps to prevent crime than to have a high incarceration rate.

Or sone kind of disaster like.. building in japan is equipped anti earthquake device so that ut will not collapse with certain scale of earthquake.. It's a prevention act as well, and cure is the fixing of building without such device. . Just another example. . Good luck!

It could also be for drug..

It can be both medical and in general .. But since it's said cure I guess it's preventing diseases but ask ur friend for more details
Good luck Eva ^^ ❤️
