Explanation:

The most common topics of public service advertisement are health and safety. The purpose of such ads is to inform the general audience about matters that usually require some change in behavior. For instance, decades ago, it was common for Brazilian television channels to run an ad about cholera.

The purpose was to prevent cholera from spreading by educating people so that they would change their behavior.

explanation:

different strategies reach different people based on their ability to understand the material.
