What type of speech is typically used when advocating for a solution to a societal issue?

Advocating for a solution to a societal issue primarily aims to influence the audience's beliefs, attitudes, or behaviors regarding that issue. Persuasive speech is crafted specifically to sway the audience's opinions and encourage action or change. It typically involves presenting arguments, supporting evidence, and emotional appeals to engage the audience and motivate them to accept a perspective or act on a proposed solution.

In contrast, informative speech is primarily focused on providing information and educating the audience without necessarily trying to change their opinions or behaviors. Descriptive speech aims to create vivid imagery and convey details about a topic, while expository speech seeks to explain or clarify complex ideas. While these types of speech are important in their own contexts, they do not inherently aim to persuade the audience to adopt a particular viewpoint or take action regarding a societal issue, which is the primary objective of persuasive speech.
