Question

what three elements have to be present for an attempt at persuasion to succeed?
hook, line, and sinker
appeal to reason, appeal to emotion, conclusion
introduction, support, call to action
messenger, message, and audience

Explanation:

In the study of persuasion in Social - Science (specifically related to communication and rhetoric), the three fundamental elements for a successful persuasion attempt are the messenger (who delivers the message), the message (the content being communicated), and the audience (the target of the persuasion). The other options do not comprehensively cover the essential aspects of persuasion. For example, "hook, line, and sinker" is a fishing - related idiom and not relevant to persuasion elements. "Appeal to reason, appeal to emotion, conclusion" focuses more on the types of appeals and a part of the structure rather than the core elements. "Introduction, support, call to action" is more about the structure of a persuasive piece rather than the elements.

Answer:

messenger, message, and audience
