• B. To persuade the audience to take action
• C. To provide the audience with unknown information
• D. To summarize existing knowledge

Answer: (C)

The primary design purpose of informative speeches is to provide the audience with unknown information. Informative speeches aim to enhance the audience's understanding of a topic by presenting facts, data, and insights that they may not be aware of. This type of speech focuses on educating the audience, ensuring they leave with a deeper knowledge or understanding of the subject matter.

While summarizing existing knowledge can be part of an informative speech, since it can reinforce what the audience might already know, the key aspect remains the introduction of new information. Additionally, entertaining the audience or persuading them to take action aligns more closely with the goals of other types of speeches, such as persuasive or entertainment speeches which focus on engaging or convincing rather than just informing.
