Which of the following are common vehicles for persuasion?

• A. Spokesperson, humor, weasel words
• B. Advertising, public relations, advocacy
• C. Editorial cartoons
• D. Public service announcements

Answer: (B)

The main idea here is understanding the channels and strategies used to influence what people think or do. Advertising, public relations, and advocacy are all broad, purposeful ways to persuade. Advertising uses paid messages to reach specific audiences with targeted appeals. Public relations shapes how the public sees an organization or issue by coordinating information, media coverage, events, and messaging to build a favorable image. Advocacy goes further by actively supporting a cause or policy, often mobilizing supporters and presenting arguments to persuade others to take action.

Other options show persuasive techniques or formats, but they aren’t as comprehensive for delivering persuasion across contexts. For example, a spokesperson, humor, or vague wording are tools or tactics used within persuasive efforts, not whole channels by themselves. Editorial cartoons are one format for persuasion, and public service announcements are a specific type of message, but the combination of advertising, public relations, and advocacy covers paid, earned, and grass-roots approaches that consistently aim to shape beliefs and actions.
